BACKGROUND
It is well-known to provide a vehicle with an energy storage system available to supply power for propulsion (transport) of the vehicle. For example, it is well-known to provide an electric vehicle (EV) with a propulsion system powered by electrical energy. A typical EV will be provided with an energy storage system in the form of a battery system comprising at least one battery (e.g. one battery module) and a drive system (e.g. comprising at least one electric motor) coupled to the battery system. The EV is powered by the supply of electrical energy from the battery system to the drive system (e.g. electric motors acting through at least one wheel having traction with the road surface) and can remain in operation until the energy storage system no longer has sufficient electrical energy (e.g. until the battery system is drained to below a certain level). Energy is typically supplied by recharging and/or replacing energy storage modules such as battery modules.
It is also known to provide a hybrid-electric vehicle (HEV) that includes at least two separate systems to provide energy for vehicle propulsion. One common type of HEV is provided with both a battery system with accompanying drive system (e.g. motors operated using electrical energy) as one propulsion system and an internal combustion engine (ICE) powered by a fuel such as gasoline with an accompanying drive system (such as a drive shaft, transmission/axle or transaxle, etc.) as another propulsion system. A hybrid vehicle may comprise any type of hybrid system to a parallel system with generally separate power plants/drive systems and a series/serial system with at least some shared components/systems for propulsion of the vehicle.
It is known to provide an EV or HEV with a battery system comprising a battery pack or battery modules. The battery pack or battery modules for the battery system are typically rechargeable. The capability (e.g. type, capacity, performance) and configuration of the battery pack or battery module is typically a design consideration of an EV or HEV. Battery modules are an important component of the battery system of an EV or HEV.
It is known to use instrumentation to acquire data from components of vehicle systems to monitor and/or control the operation of vehicle systems. For example, the battery system in an EV or HEV may include a management system to manage and monitor the use and operation of the battery/battery module during operation of the vehicle. The management system may include a processor functioning as a controller with a control program coupled to instrumentation on the battery system; the management system operates the program to provide signals that can be used to manage and monitor the battery system in use and operation. See, for example, U.S. Patent Application Publication No. 2011/0184677A1.
It is also known to provide on a vehicle (such as a work vehicle) a network or data bus that is connected to one or more vehicle systems, for example, as indicated in U.S. Pat. No. 7,206,672 (data bus in motor vehicle shown as automobile) and U.S. Pat. No. 6,665,601 (data bus in work vehicle shown as tractor). A network (or data bus) on a vehicle allows for communication of data and information between vehicle systems for use and management of the vehicle. Vehicle networks are provided in a variety of forms for a variety of different types of vehicles.
It is further well-known to provide computing devices such as smart phones/mobile telephones that are able to be connected to networks such as the internet and/or local area networks, etc. to share and access data. Such devices (which are becoming ubiquitous in large segments of society) are able to access a variety of types and content of data from a variety of network-accessible sources. Data and information available over the internet and other networks may have direct and/or indirect relation to the operation and performance of a vehicle and vehicle systems and components. Network-connectivity capability of such systems and devices is expanding; with the expansion of network-connectivity capability comes an expansion of access to data/data sources available to manage network-connected systems and devices including vehicles and vehicle systems.
Vehicles and vehicle systems are not typically operated and managed using data and information that could be accessed from data sources by means of network connectivity or configured to use the wide range of data and information that may be accessible. Vehicles and vehicle systems are typically configured and operated using a reduced or limited set of data/information from a reduced or limited set of data sources. As a result, such vehicles may not be configured or operated/managed in a manner that is optimal for performance of duties to be performed by the vehicle.

According to an exemplary embodiment, data sources will be provided to interchange data with (e.g. make data available from-to) the battery management system; data sources will comprise various sets of updated/recorded and stored data records associated with the battery system in the management of the battery system. According to an exemplary embodiment, the data records available on the network can be used at a data center for an analytics function to manage the use of battery modules in vehicles, for example, to facilitate life-cycle management of each battery module in a battery system or inventory (e.g. the life-cycle for the battery module is managed according to data records to suggest recommended use of each battery module). Data records available on the network may be used to optimize use of battery modules in vehicles according to battery type, based on state of charge of the battery module, state of health of the battery module, operation history of the battery module; the battery module recommended by the management plan/system for a battery system configuration for a vehicle performing duty following a route may be based on predicted needs in consideration of corresponding data records for each installed/available battery module (e.g. type, rate of energy charge and discharge, energy storage capacity, depth of charge and discharge or number of charge-discharge cycles, etc.).

Predictive Controller Implementation
According to a preferred embodiment, the management system (shown schematically in FIGS. 1A-1B, 2A-2B and 13) will comprise a predictive control system configured to use data from network-connected data sources (see TABLES A-J) to operate a management/control program through a management plan (implemented through a computing system, see FIG. 5). FIG. 16 is a schematic flow diagram of the method of operation of a management system with predictive control for an energy storage system for a vehicle according to an exemplary embodiment. (FIG. 17 shows the use of data from the method to update the data model of a component such as a battery module used by the predictive controller of a battery system.)
According to a preferred embodiment, the management system is configured to employ program and routines that implement a predictive controller (e.g. operating program or routine) to enhance system performance and optimize operation for a system configuration in the operating conditions; the predictive controller of the system may be configured to use stored/available data and information to plan and predict and anticipate and evaluate conditions and then implement control routines for the system in operations as to optimize performance against specified or selected criteria (or according to a selected mode of operation in the conditions of operation (e.g. in real-time). See FIGS. 13-14 and 16, 18. See also TABLES A-J.
According to an exemplary embodiment, the predictive controller routine of the management system will be configured to use data and information including the current battery system configuration to manage (e.g. optimize) energy storage and energy discharge for the battery system. According to a preferred embodiment the management system will be programmable to manage wide variety of battery system configurations that will comprise packs/battery modules of a wide variety of types over a wide variety of conditions (e.g. use/demand, operating, environmental, etc.). See FIGS. 10 and 16.
According to an exemplary embodiment as indicated in FIG. 16, the predictive controller of the management system will use (among other data) monitored/internal configuration and state of charge/health information as to each battery module from the battery system in combination with external/acquired information such as driver identity, anticipated duty/use, vehicle driving patterns, location/route, time of day, traffic and weather, regulations and restrictions, local energy/fuel cost and availability, other programming or user input information (e.g. as to preferences, usage, duty/load, etc.) to manage the operation of the battery system according to a management plan or program. The management plan is based on predicted conditions of operation (see TABLES E, G, H, I) for the battery system and vehicle and objectives for the system operation (see TABLE J) in view of the configuration (see TABLES B, C). The predicted conditions may comprise operating conditions of the vehicle expected in the duty, such as environmental conditions in which the vehicle is expected to operate, route topography and grade, etc.
According to an exemplary embodiment, the management system will be configured to implement (predictive) energy transfer to allow control and optimization of the installed battery system configuration in anticipated operating conditions for the duty/route of the vehicle according to considerations and objectives. See TABLE J. The management plan may comprise the plan for the entire route or duty to be performed by the vehicle and contingent plans or routines for stages or segments of the route in the operating conditions. For example, if the route includes travel along a variety of segments having varied road conditions such as uphill grades and downhill grades and/or in segments in varied traffic conditions such as city and highway operation, the management system will be configured to create and operate plan segments as to manage the battery system (e.g. charge, discharge and transfer of energy) for each segment of the plan.
The management plan will be created in accordance with the conditions predicted to be encountered by the vehicle in the duty/route according to the capability of the vehicle as configured. For example, with a battery system configured with a battery pack comprising high-rate battery modules, operation of the vehicle by the plan may be directed as follows: (a) advance of anticipated periods of available energy from the regenerative braking system such as on downhill grades or in stop-and-go traffic conditions the battery system will discharge high-rate battery modules so that regenerative power can be accepted and used for charging; (b) in advance of anticipated increased demand such as on uphill grades or entering an expressway from an on-ramp the system will charge the high-rate battery modules so that power is available for discharge and acceleration of the vehicle; (c) identified available periods of reduced intensity of use can be used for management operations such as voltage-level shifting or cell balancing between battery modules. According to an exemplary embodiment, if the vehicle comprises alternative systems/sources of energy supply (such as a waste heat recovery system or a solar panel array configured to provide energy for recharging battery modules), the management system can use route/direction and weather and time of day to plan optimize utilization of the system/source to charge the battery system.
According to an exemplary embodiment, if any battery module monitored is determined to be exhibiting a problem or potential malfunction, the management system can be configured to adapt to the condition, for example, to adjust the determined capacity of the module, to limit use of the module (e.g. pending further evaluation), to run a set of diagnostic tests, to perform a re-conditioning operation on the module, etc. The predictive control system can evaluate components of the battery system in an effort to prevent serious malfunction while not comprising functionality (when possible) by adapting the management plan. In operation, the management system will provide a communication to the operator (and others), will adjust the program/routine for the route or duty and will adjust demand on the other battery modules in the battery system in the operating conditions. For example, if a battery module is determined to have developed an increased internal resistance or impedance (a condition likely to cause potentially higher operating temperatures) the management system can direct the thermal management system to attempt to maintain proper/desired operating temperatures in the battery system (e.g. cooling the battery compartment) while limiting the use of the battery module so that the risk from the battery module is reduced (e.g. the module is used only at or within a reduced ambient or environmental temperature range and is used in a reduced-demand manner such as for backup capacity rather than as high-rate battery module). According to an exemplary embodiment, a battery module that is otherwise susceptible to overheat conditions can be managed to reduce the risk of serious malfunction of the system (e.g. a risk of failure or fire/hazard); a battery module that is at a reduced capacity can be managed to reduce the risk of serious malfunction of the system (e.g. a risk of anticipated energy called upon by the vehicle not being available).
According to an exemplary embodiment, the array of battery modules in the battery system can be managed during use so that after a use event such as sudden braking and supply of regenerative energy to high-rate modules in the battery system a routine can be performed to balance the voltage levels of the battery modules (e.g. to reset voltage levels for the battery modules to a pre-determined system baseline voltage level); for example, on a route that may comprise intermittent periods of relatively intense high-rate charge and discharge of energy and then reduced intensity of energy demand/use, the management system may be programmed to perform a periodic voltage-leveling operation during use of the battery system.
The system may be configured to coordinate management of the battery system with operation of other vehicle systems. For example, the management plan may predict (based on energy cost and use/demand) when a power plant or other energy source can or should be used for recharging the battery system.

For example, a vehicle system may have a user interface provided in the vehicle instrument panel (e.g. within the standard vehicle user interface), in a separate control panel (e.g. on or associated with the vehicle system), in a restricted-access area (e.g. for a rental vehicle with the control panel/user interface in a restricted-access location such as a vehicle trunk that is not intended to be accessed by the operator but only by an authorized service attendant of the dedicated interface). According to an exemplary embodiment, the user interface can be provided over a network (e.g. in a manner used for network-connected devices of a variety of type) so that data access and updates as well as system/data operations (such as status review and data/firmware/program maintenance and updates) can be provided from external computing locations (e.g. with a standard program/computer interface or other application including an application program (e.g. such as a “mobile app” or program available for a mobile device such as a smart phone or tablet computer).
Information provided at a user interface for the system may include regular (or on-demand) real-time reporting and communication of operator status (e.g. monitoring of selected systems), system capacity and availability, usage history, use suggestions/recommendations, current forecast conditions, reminders, cautions/warnings, maintenance suggestion/recommendations, messaging (e.g. text or email), GPS data/maps, facility/resource locations and types, current operating mode, system help, etc. Options provided for a vehicle to a user/operator (e.g. driver of vehicle or fleet manager or data center) may include driver identification/preferences, data storage operations (save/store/open/load/etc.), GPS (e.g. routing, display, etc.), operating modes (e.g. power/efficiency/balanced/custom/etc.), operating programs (for management systems), network access options, internet/browser access, communications options (e.g. device/network interface and connectivity), emergency/911 contact, trip plans and profiles, resource/facility use plans, maintenance and service plans, condition report format, status report format, etc. Data communications at a user interface may be presented in any form such as visual, audio, audio-visual, etc.
According to an exemplary embodiment, the management system can be configured to provide a user interface/display through a dedicated display/device or to allow display/communication and access through existing or installed/other systems in the vehicle or other computing devices available on the network through an application/program or by an internet/web browser (or by other means). According to an exemplary embodiment, the management system will be configured so that data and information (including as to real-time status and operation) can be accessed by network when network access is available by designated users (e.g. at work/home computing devices, by mobile devices/smart phones/tablets, at data centers, at fleet management centers, at other vehicles, etc.). See FIGS. 1A-1B, 3 and 4A-4C.

For example, a first battery pack may be configured to provide a type of battery module that allows a relatively higher rate of discharge and charge acceptance (e.g. high rate module); a second battery pack may be configured to provide a type of battery module that has a relatively higher energy storage capacity (e.g. high capacity module); a third battery pack may be configured to provide a type of battery module that allows relatively deeper discharge of total energy in operation (e.g. deep discharge module); a fourth battery pack may be configured to provide a type of battery module that allows relatively more use cycles or total energy throughput during useful life (e.g. high cycle life module). Expected characteristics and performance of the battery system (and the vehicle in duty) can be modified to match or suit conditions by selective configuration of the battery pack/battery modules. Referring to FIGS. 9A-9C, configurations of battery packs for the battery system of a vehicle are shown schematically according to an exemplary embodiment. FIGS. 11A-11D each show schematically a vehicle with a battery system providing a battery pack with different configurations of battery modules according to exemplary embodiments. According to a preferred embodiment, the battery system will comprise at least two battery packs with each battery pack comprising at least two battery modules. As indicated schematically in FIGS. 9A-9C, 10A-10G and 11E, the battery system/pack may comprise a variety of types of battery modules or battery cells (e.g. component batteries/cells and modules of different structure and components/capability, chemistry, etc.).
As shown schematically in FIG. 11E, interchangeable battery modules for the vehicle may be categorized in inventory (available for installation in a vehicle and/or selected and installed in a battery system/pack for in-vehicle use) according to type and various other characteristics such as age, performance, remaining life, phase of life-cycle, etc. For example, as indicated in FIG. 11E, interchangeable battery modules may comprise multiple types; type A is a high-rate charge/discharge battery module; type B is a high-capacity battery module; type C is a battery module designed to withstand harsh environmental conditions (e.g. temperature extremes, shock/vibration, etc.); inventory may comprise various other types of battery modules indicated such as a “standard” type designed for standard use considerations. For a planned duty or route predicted to involve a relatively wide range of operating conditions, the vehicle may be configured with a composite battery pack having one battery module of each type (A, B, C) as shown schematically in FIG. 11A; for a duty or route involving travel or a long distance or high energy demand with reduced ability to recharge, the vehicle may be configured with a battery pack having a multiple battery module of a high-capacity type (type B) as shown schematically in FIG. 11B; for a duty or route involving harsh environmental conditions, the vehicle may be configured with a battery pack having multiple battery modules of a type (type C) designed/manufactured to withstand harsh conditions as shown schematically in FIG. 11C.
Referring to FIG. 19, a method of configuring an energy storage system such as a battery system with interchangeable components such as battery modules is shown schematically according to an exemplary embodiment. Data from data sources (see e.g. TABLES B-I and FIGS. 2A, 3 and 15A-15B) is used to determine the anticipated use/duty for the vehicle/system and to determine available configurations of the system (e.g. based on the vehicle design and/or on available inventory of components such as battery modules); a recommended configuration of the system is provided in the form of a report/recommendation of components to install (e.g. a selective combination of interchangeable battery modules of type/phase/condition); the vehicle/system can be configured as recommended and the recommended configuration can be validated for use and operation (e.g. by testing to ensure that the system and components operate as planned/intended); override of the recommended configuration may be permitted at or during installation (e.g. based on factors identified by persons such as service center workers or operators that may not have been identified by the system). The vehicle/system with the recommended or directed configuration of the energy storage system is then ready for use/operation; according to an exemplary embodiment, as indicated, use/operation of the vehicle with the battery system as configured may provide data that can be acquired/stored and made available for future use according to the method and system.
Referring to FIGS. 20A-20C, where the energy storage system is a battery system with interchangeable battery modules, different configurations of the battery system may be recommended and installed/implemented for different anticipated operating conditions through installation of different types of battery modules in the vehicle. See also FIGS. 11A-11E. For example, where battery types comprise a high energy type (e.g. with enhanced range/capacity) and a high power type (e.g. with enhanced rate of power delivery/energy transfer), the vehicle may be configured with an objective to enhance performance in the corresponding anticipated conditions of operation: for typical commuting, two high power modules and four high energy modules (FIG. 20A); for a long trip (accepting reduced acceleration but increased range), six high energy modules (FIG. 20B); for intensive recreation activity such as street racing or mountain driving, five high power modules and one high energy module (FIG. 20C). As indicated, with various other (interchangeable) battery modules of various other type/phase/condition, the battery system can be configured to provide a wide range of performance characteristics adapted or adaptable to suit intended specialization/optimization objectives or requirements comprising or according to any of a wide variety of other objectives and considerations such as energy efficiency, total cost, life-cycle management, components availability, etc. See TABLE J.
As shown schematically in FIGS. 21A and 21B, the vehicle may be designed to facilitate the use of specialized components; for example, the battery system of the vehicle may be adapted to accommodate different types of battery packs/modules to permit specialization/optimization. See e.g. FIG. 7C. As indicated in FIG. 21A, a bay or receptacle for a battery pack/module may be configured for a specific type or category of battery pack/module; for a high power module the bay may be provided with an enhanced physical and electrical interface as well as with enhanced instrumentation and monitoring/management (e.g. thermal management and circuit protection system); a standard bay may have a standard interface with a standard instrumentation and monitoring/management arrangement. As indicated in FIG. 21B, a specialized component such as a super high power battery pack/module may fit for installation and use in the high-power bay of the battery system/vehicle; standard components may fit interchangeably in each standard bay. (As indicated in FIG. 9D, according to an exemplary embodiment, the battery system may be configured to be operated with an empty bay or with a disabled battery module.)
Inventory Management System
According to an exemplary embodiment, a system can be implemented for managing the inventory and use/deployment of components of vehicle systems such as the energy storage system. As shown schematically in FIGS. 11E and 22-26, according to an exemplary embodiment where the energy storage system is a battery system comprised of components in the form of interchangeable battery modules an inventory management system (IMS) may be provided. As indicated in FIGS. 22-26, the inventory management system (using data available from data sources) can be provided to manage the use and deployment of battery modules from the supply chain and/or inventory/stock according to considerations relating to the battery modules and other considerations such as the vehicle, duty, climate/condition, maintenance, etc. See also FIGS. 3, 4A-4C and 11E and TABLES A through J (data categories and sources).
Referring to FIG. 11E, a center for servicing and configuring battery systems for vehicles is shown schematically according to an exemplary embodiment. As indicated in FIG. 11E, the vehicle service center or location for service/maintenance of a vehicle may maintain an inventory of battery modules of different types for configuring a battery pack for a vehicle. Categories of battery/battery module type may include a high capacity, high power, high energy, deep discharge, extended cycle life, high efficiency and rapid recharge, etc. As indicated in FIG. 11E, the battery pack for a battery system can be configured and reconfigured with various combinations of battery modules of different types depending upon the situation and planned/predicted use of the vehicle from inventory of interchangeable battery modules: for example, type A is a high-rate charge/discharge battery module; type B is a high-capacity battery module; type C is a battery module designed to withstand harsh environmental conditions (e.g. temperature extremes, shock/vibration, etc.); type D is a “standard” battery module for standard/typical use. Interchangeable battery modules for the vehicle may be categorized in inventory (and selected and installed in a battery system/pack for in-vehicle use) according to type and various other characteristics such as age, performance, remaining life, etc. For planned duty or route predicted to involve a range of operating conditions, the vehicle may be configured with a composite battery pack having one battery module of a different type (A, B, C) as shown schematically in FIG. 11A; for a duty or route involving travel or a long distance or high energy demand with reduced ability to recharge, the vehicle may be configured with a battery pack having a multiple battery module of a high-capacity type (type B) as shown schematically in FIG. 11B; for a duty or route involving harsh environmental conditions, the vehicle may be configured with a battery pack having multiple battery modules of a type (type C) designed/manufactured to withstand harsh conditions as shown schematically in FIG. 11C. In standard or typical use conditions, the vehicle may be configured with a battery pack of all standard type (e.g. type D).
As indicated in FIG. 22, battery modules from a local inventory (e.g. at a service location) or remote inventory (e.g. available to a service location upon delivery) can be located and installed in battery system for vehicles in a manner intended to optimize performance of the battery systems in which the battery module is installed. As indicated in FIGS. 23-24, the inventory management system performs a set of functions in the management of an inventory of battery modules; each battery module in the system may be categorized by type and status and availability to an outlet (among other considerations). As indicated, data as to type may relate to performance characteristics and classifications (as well as chemistry/design, etc.); data as to status may relate to age/phase of life-cycle, condition (e.g. state of charge/state of health), use history (e.g. events and prior use/performance) and current location (e.g. information as to availability). See also TABLE B.
As indicated in FIGS. 22, 24 and 25, according to an exemplary embodiment, the inventory management system may be configured to manage and deploy inventory of components according to a wide variety of considerations using data available to a data center (and/or other computing systems); inventory may be available as local inventory at a local site such as a service center/outlet where battery systems are configured and installed in vehicles or are available as remote inventory from various other sites such as storage locations, warehouses, etc. (e.g. sites within a particular region), as indicated schematically in FIG. 22. Inventory may be shared and managed within a region, within an entity (e.g. company, enterprise, institution, cooperative, etc.) or according to other arrangements (e.g. managed by a vendor/supplier, etc.); according to an exemplary embodiment, data as to inventory composition and availability is made available to vehicles, vehicle operators, service centers, managers/fleet managers, etc. over a network (see FIGS. 18 and 22). As shown schematically in FIGS. 11A-11E, 20A-20C and 22, according to an exemplary embodiment in operation of the inventory management system, vehicles may have a battery system installed in any of a wide variety of configurations of battery modules using available inventory of battery modules (e.g. access at a service center or similar facility for installation).
A method of implementing an inventory management system according to an exemplary embodiment, is shown schematically in FIG. 25; as indicated, the method uses data from data sources including battery module data and other data (see FIGS. 14, 15A-15B and 23 and TABLES A and B). The vehicle (e.g. vehicle type, vehicle system configuration, etc. see TABLE C) is determined; in addition the anticipated duty of the vehicle (e.g. available resources, route, activities, duration, operator, etc., see TABLE D) as well as conditions of operation (e.g. time of day, weather, traffic, etc., see TABLES E, F, G, H and I) can be considered (among other considerations) in allocation and development of inventory of components such as battery modules for a battery system of a vehicle as indicated in FIGS. 11A-11E and 22-25. According to an exemplary embodiment, there will be an assessment of available local inventory of components and recommendation of a system configuration; there is an option for override of the recommended system configuration (e.g. the configuration is not considered to be optimal, acceptable, possible, etc. due to identified factors or considerations) and can be an alternative assessment of remote/regional inventory of components that can be made available (e.g. in combination with local inventory of components) for installation in a vehicle. According to an exemplary embodiment, data from data sources available over a network can be accessed in operation of the method/system (e.g. in real time). The vehicle as configured is then able to be put into service in order to perform the duty under the conditions of operation (and performance of vehicle systems and components in actual operation can be monitored), as indicated in FIGS. 1A-1C and 2A-2B.
Life-Cycle Management
According to an exemplary embodiment, the system/method can be implemented to manage the life-cycle of components of vehicle systems. According to an exemplary embodiment the vehicle system may be an energy storage system such as a battery system with battery modules as components, as indicated schematically in FIGS. 24A-24B. For example, a battery module may be characterized with a data set that indicates (among other data) the status including age/phase, condition and use history of the battery module, as indicated in FIG. 23.
In the management of the life-cycle of a battery module, operating parameters (such as categories of use) may be correlated to data as to the status/phase of life-cycle of the battery module. According to an exemplary embodiment, as indicated in FIGS. 24A-24B, a new battery module is indicated as A phase; a mid-life battery module is indicated as B phase; an end-of-life battery module is indicated as C phase. A battery module may be classified as in a phase based on evaluation of data such as age, time in service, charge-recharge cycles, energy throughput, service/maintenance records, use/event history, etc. as well as measurements of performance and condition (e.g. state of health, impedance, capacity, etc.); periodic reclassification of the battery module may occur during the life-cycle of an interchangeable reusable component such as a battery module. As indicated, the cost (e.g. pricing, use fee, etc.) and warranty terms (e.g. length and conditions) may vary for a battery module during each phase of a managed life-cycle; for a battery type, a battery module at new phase (A phase) will allow or command a different value (e.g. higher price/use rate) than a battery module at mid-life phase (B phase), for example. As also indicated, the maintenance plan (e.g. reconditioning method and frequency etc.) may vary during each phase of a managed life-cycle for a component such as a battery module.
As indicated schematically in FIGS. 24A-24B, categories of operating parameters for a component of a vehicle system may include the vehicle type, the duty type, climate and conditions, etc. Vehicle types may include heavy-duty work vehicles to unoccupied light-duty vehicles as well as other vehicles in of a wide range, generally indicative of the anticipated demand on the vehicle system and components. Duty types may be characterized by the intensity and frequency of demand as well as the frequency/availability of servicing and level of monitoring; duty types may also be characterized by fault/failure tolerance and redundancy as well as safety considerations. Climate conditions and environmental conditions may be characterized by temperature extremes (e.g. excessive heat or cold), humidity and precipitation, types of use (e.g. land, marine, road, agriculture, mining/excavation, etc.), shock/vibration, etc.
As shown schematically in FIGS. 24A-24B, according to an exemplary embodiment, each category of operating parameters can be given a classification (or class) of A or B or C (as corresponding to the life-cycle phase of the battery module most suited for use under the classification of operating parameter). As indicated schematically in FIG. 9D, a battery system may comprise a set of battery packs having battery modules of a different type or age/stage of life-cycle. See also FIGS. 26A and 26B.
Referring to FIGS. 24A-24B, use under operating parameters in the A classification would be characterized by greater relative demand for performance and need of capability/reliability as would be expected from a battery module in the A phase of life-cycle; use under operating parameters in the B classification would be characterized by moderate relative demand for performance and need of capability/reliability as would be expected from a battery module in the B phase of life-cycle; use under operating parameters in the C classification would be characterized by moderate relative demand for performance and need of capability/reliability as would be expected from a battery module in the C phase of life-cycle. As indicated, a battery module in each respective phase of life-cycle could be managed according to a maintenance plan for the phase of life-cycle. As the battery module advances along the life-cycle, the level of demand/intensity of the recommended operating parameters of use are able to be reduced; the cost and warranty of the battery module may also be reclassified (e.g. reduced) as the battery module advances along the life-cycle.
According to an exemplary embodiment, the inventory management system will classify available battery modules by phase as well as type and other data available through data source. As indicated, according to an exemplary embodiment, in the A (new) phase of life-cycle, the battery module would be capable of performing to standard or specification under operating parameters of use in the A or B or C classification (or class), for example, in an A or B or C class duty type in an A or B or C class vehicle type in climate/conditions in an A or B or C class (see FIG. 24B). At the mid-life phase (B), the battery module is considered to be capable of performing to a reduced standard and specification of operating parameters in the B class (e.g. less demanding than the A class) (see FIG. 24B). As the battery module reaches the end-of-life phase (C), the battery module is not considered to be capable of performing to a standard or specification other than the C class of operating parameters (e.g. a less demanding class of duty in a less demanding type of vehicle/system in a less demanding climate and less demanding conditions than the B class) (see FIG. 24B). As indicated, according to an exemplary embodiment, a battery module can be deployed for use in a manner that matches the class of use (e.g. operating parameters) with the present condition of the battery module to be installed which will allow for more reliable performance of the battery module during the life-cycle of the battery module.
As indicated, according to an exemplary embodiment, a battery module in a managed life-cycle will be expected to pass through each phase of life-cycle and be expected to perform according to the operating parameters of each phase/class in each phase of the life-cycle. Data for a battery module (or types of battery modules) can be acquired (e.g. from testing or from operating vehicles/vehicle systems) to determine what conditions of operation accelerate aging or deterioration of performance of a battery module; data then can be (stored in a database and) used to enhance the accuracy of performance of the life-cycle management systems for battery modules. See e.g. FIGS. 27B-27C and 30A-30B.
As indicated in FIGS. 11E, 15B and 17, according to an exemplary embodiment, the battery module can be provided with an identifier device such as a tag configured to provide, store and/or interchange data relating to the battery module (e.g. identifier, RFID tag, serial number, etc.). According to an exemplary embodiment, as shown schematically in FIG. 17E, the tag or identification may provide current/updated condition and phase of life-cycle that can be used and/or stored in data records for the battery module (see FIG. 15B) along with current (updated) data model to reflect predicted performance at the current life-cycle phase (see FIG. 17); other data sources may also contain the operational/acquired data for each battery module (e.g. for a period of time or for the time of service to date). According to an exemplary embodiment, as indicated schematically in FIG. 24B, a method of life-cycle management, monitoring of the battery module (e.g. according to standards and specifications) will indicate when a battery module is to be considered in the next phase of life-cycle; an event of misuse or abuse or other history event (e.g. thermal/high temperature exposure of overheating, physical impact or accident, overcharge or drain, etc.) may cause or indicate that a battery module be reclassified to another phase (e.g. from phase A to phase C, subject to reconditioning).
After the end-of-life phase, the battery module is expected to be recycled; according to a particularly preferred embodiment, the inventory management system can work to relocate battery modules for use in vehicles or in inventory at a location nearer recycling facilities at the end-of-life phase as to reduce the distance and cost of shipping to recycling facilities. According to an exemplary embodiment, prior to being removed from service and transported to a facility for recycling, battery modules may be reconditioned and used in non-vehicle applications such as stationary power (or backup) under suitable monitoring conditions to extend further the life-cycle of usefulness performance of the battery module.
Data Analytics
The system may provide a data analytics system for vehicle systems and components. See FIGS. 13, 16-17, 27A-27D, 28, 29 and 30A-30B. As indicated schematically in FIGS. 16 and 17, data acquired from data sources can be processed for a data analytics function; the data analytics function/system can be used to improve the detail or accuracy of data sets and data models for components of the vehicle systems. For example, actual performance data for a particular type of battery module may be processed in an analytics function to improve the accuracy of the data model associated with a battery module; an updated data model may be made available to management systems for vehicles using the battery module in a battery system. See FIGS. 27A-27D, 28-29 and 30A-30B.
Referring to FIGS. 27A-27D, 28-29 and 30A-30B (see also FIG. 13), a data analytics function (e.g. system and method) for vehicle systems and components is shown schematically according to an exemplary embodiment.

The database may also include a library of stored operating programs or plans that have been used, developed, created or otherwise made available to a management system for vehicle system such as the battery management system of a battery system. See FIGS. 12B, 13 and 16 (e.g. management plan developed for a vehicle system). According to an exemplary embodiment, the analytics system is able to use and access the data acquired and aggregated and stored in the database to perform an analytics function for one or more components of the vehicle system and/or for data sets used in the management and operation of the vehicle.
Referring to FIG. 27C, the analytics system is shown schematically and representationally by functions according to an exemplary embodiment; the functions of analytics system are performed by one or more computing systems (see FIGS. 5 and 28) using programs or routines (e.g. algorithms, models, applications, application program interfaces/APIs, tools, etc.).

According to an exemplary embodiment, the analytics system may also be configured to distribute/share and commercialize data such as by performing or allowing data mining and/or by packaging and monetizing data records (e.g. by sale, license, etc.).
Referring to FIG. 27D, according to an exemplary embodiment, the analytics system is configured to provide enhanced functionality for management and operation of vehicles and vehicle systems (including vehicle fleet management, see e.g. FIGS. 1A-1C, 2A-2B, 12A-12B, 28 and 31), for inventory management systems for components including for life-cycle management (see FIGS. 23-25 and 26A-26B), for data centers and other computing systems/computing devices connected to various networks that allow sharing of data sources (see, e.g. FIGS. 3, 4A-4C, 12A-12B, 18 and 23), and for other technical/commercial systems uses and services (e.g. component developers, designers, manufacturers, vendors, etc., see e.g. FIGS. 29 and 30A-30B). According to an exemplary embodiment (as shown in FIGS. 27A-27D), the analytics system provides data, data sets and data models to the vehicle in the form of updated data models for components of vehicle systems such as battery modules of a battery system (see also FIGS. 15A-15B and 17), data sets and operating programs for management/control systems for vehicle systems such as the battery management system/controller for the battery system (see also FIGS. 13, 16 and 18).

According to an exemplary embodiment, a fleet management system (FMS) is provided for a group or fleet (F) of multiple vehicles having vehicle systems such as an energy storage system. See FIGS. 12A-12B and 31.
Referring to FIG. 12A, a set or fleet of vehicles each with a management system with a data center connected by network through a computing device is shown schematically according to an exemplary embodiment. See also FIG. 12B (showing fleet of vehicles with identified battery systems). According to an exemplary embodiment, the systems and methods for configuration, management, operation, etc. of an individual vehicle having an energy storage system such as a battery system with interchangeable components such as battery modules will apply to a fleet comprising one or more such vehicles.
The fleet of vehicles is connected by network to a computing system at a facility from which fleet management operations (or some portion of fleet operations) may be performed; according to an exemplary embodiment as shown schematically, the computing system comprises a computing device C with a network interface/adapter N and a user interface UI. See FIGS. 4A-4C and 12A-12B. At computing device C, a person will be able to access the management system of a network-accessible vehicle in the fleet and perform operations such as programming of certain vehicle systems, uploading and downloading data and information, diagnostic tests and monitoring, etc. Data records available may be accessed from information from a mobile device, such as a smart phone, a mobile phone, a tablet, etc. See FIG. 18.
Referring to FIG. 31, system and data operations for a fleet management system comprising a fleet of vehicles with vehicle systems, such as an energy storage system comprising a battery system with components such as battery modules, is shown schematically according to an exemplary embodiment (see also FIGS. 1A-1C, 2A-2B and 12A). The fleet of vehicles comprises each of the vehicles with vehicle systems as installed and/or configured/configurable with components to perform functions and duties such as travel on designated routes for designated activities under the operation of drivers/operators: data and information as to the fleet and functions/duties is provided to the computing system and database for the fleet management system along with data and information as to vehicle systems and components (e.g. type and status, see FIGS. 14, 15A-15B, 22 and 26A). According to an exemplary embodiment, the fleet management system uses data and objectives (e.g. criteria, objectives, considerations, weighting, etc. for operation of the fleet such as cost efficiency, reducing total cost, extending component life, etc. as determined and implemented) in an operating program/algorithm to manage fleet operations; the fleet management system identifies options (among other considerations) for configuration of vehicles and vehicle systems and for routes/duties for vehicles in the fleet. See also TABLES A-J. According to an exemplary embodiment, the fleet operations comprise (among other functions) assignment of route/duty to specific vehicles in the fleet, configuration of vehicles and vehicle systems with components for the duty (see e.g. FIGS. 11E, 19, 20A-20B, 21A-21B, 23, 25 and 26A-26B), loading of a program/plan for management and operation of each of the vehicles and vehicle systems (see e.g. FIGS. 3, 4A-4C, 13 and 16-17) and monitoring of the fleet of vehicles.

As indicated in FIGS. 4A-4C (and 12B), vehicles may be operated individually (e.g. as a personal/family or small-business vehicle) or may be operated in fleets (e.g. by entities such as commercial entities, rental agencies, governmental/municipal entities, etc.). According to an exemplary embodiment, multiple individual or fleet vehicles may be aggregated or associated in one or more groups or fleets (e.g. fleets or groups according to common or shared attributes such as type, manufacturer, model, location, service center/pattern, component configuration, driver/operator association or type, use or use history, etc.); data/network connectivity and data operations for groups (formal, informal, or selective) may be configured based on the needs, interests or capabilities of the group/fleet and network/user interfaces and nodes developed or configured for vehicles (and operators of vehicles) in the group or fleet. For example, a group of vehicles sold by or serviced at a vehicle dealer, from a particular manufacturer, registered with an association or club (e.g. automobile association/club, etc.) or otherwise affiliated in some manner or with a collective interest/purpose may be provided with shared network and data connectivity (e.g. operated under a fleet management system and with shared use of related data/information access).
As indicated schematically in FIGS. 2A-2B, 3, 4A-4C, 12A-12B and 31, the management system for a vehicle or fleet of vehicles may be configured to allow network-connected access from various other computing systems, such as mobile devices, home/office computers, fleet/service center, data center, etc.
According to an exemplary embodiment, vehicles within a fleet may also be operated according to a management plan/program and with a configuration modified for a particular operator/driver or use/duty.

Fleet management operations may be coordinated with an analytics function to use data to build, share and update databases (e.g. data sets, data models, etc. using actual performance data from components in operation vehicles in conditions or test data) that can be used by multiple vehicles and vehicle systems (both within a fleet and outside a fleet of vehicles).
SCENARIOS/EXAMPLES
The operation and practice of the methods/systems and components can be further described with reference to various scenarios/examples in various conditions for vehicle systems such as an energy storage system shown as a battery system for a vehicle. See e.g. FIGS. 1A-1B and 2A-2B.
Example A—Personal Vehicle Configuration/Reconfiguration
Data sources make data available to the vehicle and operator as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data inputs comprise anticipated vehicle use/duty and available battery configurations for the vehicle.
For a battery system with interchangeable battery modules, different configurations of the battery system may be recommended and installed/implemented for different anticipated operating conditions through installation of different types of battery modules in the vehicle.
In operation according to an exemplary embodiment, the system provides direction for configuration of the battery system based on data available from data sources. As indicated, with various other (interchangeable) battery modules of various other type/phase/condition, the battery system can be configured to provide a wide range of performance characteristics adapted or adaptable to suit intended specialization/optimization objectives or requirements comprising or according to any of a wide variety of other considerations such as energy efficiency, total costs, etc. See TABLE J. Battery types comprise a high energy type (e.g. with enhanced range/capacity) and a high power type (e.g. with enhanced rate of power delivery/energy transfer). The vehicle may be configured with an objective to enhance performance in anticipated conditions of operation: for typical commuting, two high power modules and four high energy modules (see FIG. 20A); for a long trip (accepting reduced acceleration but increased range), six high energy modules (see FIG. 20B); for intensive recreation activity such as street racing or mountain driving, five high power modules and one high energy module (see FIG. 20C).
Actual use and performance data will be provided to a database and data center for data analytics.
Example B—Single Vehicle Use/Management
Data sources make data available to the vehicle as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data inputs comprise predicted route (e.g. based on prior GPS history or user input) plus topographic/road information plus predicted ambient temperatures (cold weather) plus battery capacity and capacity versus discharge rate, plus battery charge state, etc.
Data analysis determines that the intended route has steep slopes which in cold ambient conditions will drain batteries at high rate, reducing overall capacity sufficiently to require early recharge (before end-of-route).
In operation according to an exemplary embodiment, the management system provides that recommended plan for control output is to limit maximum sustained power drain (and therefore limit uphill speed) until battery internal temperature has risen to a higher value. The system may also activate a battery heater (consuming some stored energy) to raise battery temperature before encountering high-drain part of the route.
If battery modules are interchangeable (swappable) modules, the system may recommend or select installation of high-power batteries versus high-energy batteries. The system will provide alerts and communication to advise the user/operator to either limit total distance traveled (provide a message “don't run extra errands today”) or to recharge the battery module during the day. Communications may be provided to the user/operator at a user interface in the vehicle as well as to computing devices such as a home computer, table computer and smart phones.
Actual use and performance data will be provided to a database and data center for data analytics.
Example C—Single Vehicle Use/Management
Data sources make data available to the vehicle as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data inputs comprise predicted route, traffic prediction (e.g., heavy traffic due to a scheduled sports event at/or along the route), battery capacity and regenerative charge efficiency, battery charge state, driver habits (tendency of the operator to be impatient in traffic and use of abrupt acceleration
Data analysis determines that there is a significant probability that the vehicle will be caught in stop-and-go traffic with low battery charge state at end of day; resultant in frequent heavy discharge/charge cycles at low charge will tend to decrease battery life (and use history will be recorded on data/ID tag on battery module as data record).
In operation according to an exemplary embodiment, the management system provides that recommended plan for control output (in addition to other measures, e.g., limiting maximum discharge rate) should include exceeding normally optimum recharge rate during a mid-day charging stop so that battery charge state will be higher at the end of the day.
In operation according to an exemplary embodiment, the system provides that recommended plan for configuration with interchangeable modular batteries is to select at least one module with high cycle life to accommodate stop-and-go conditions.
Actual use and performance data will be provided to a database and data center for data analytics.
Example D—Small-Fleet Management (e.g., Delivery Trucks, Buses)
Data sources make data available to the vehicle as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data is available to a data center to perform fleet management operations for a fleet of vehicles with battery systems.
Routes and battery usage are predictable and are normally set up for efficient use of battery modules; e.g., battery packs with new (highest-capacity) battery modules are installed in vehicles with most demanding routes. However, a predicted weather event (very high temperatures) will make most demanding routes exceed the energy capacity of the best battery packs, due to air conditioning loads and battery losses at high temperature (as predicted and based on data/computation models).
In operation according to an exemplary embodiment, the management system provides that recommended plan for control output is to identify vehicles with battery systems comprising at-risk battery modules and assign special routes, modified to reduce demand; plan will also recommend swapping vehicles partway through the day between high and low demand routes, or otherwise provide additional support resources for possible in-field events/failures.
In operation according to an exemplary embodiment, the system provides that recommended plan for a fleet is to deliberately assign highest-capacity battery packs to less demanding routes that can be completed on one charge and low-capacity batteries to high demand routes with vehicles swapped out (e.g., use “reserve” vehicle to replace a “depleted” vehicle halfway through the day).
Additional inventory of new high-capacity battery modules is ordered from a regional center as needed; failed battery modules are designated in life-cycle management system and reconditioned or recycled.
Actual use and performance data will be provided to a database and data center for data analytics. Data models for battery module types will be updated to reflect actual performance data in the demanding route/weather conditions. Data will be shared with subscribers including other fleet managers and component/vehicle producers.
Example E—Large-Fleet Management (e.g., Delivery Trucks, Buses)
Data sources make data available to the vehicle as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data is available to a data center to perform fleet management operations for a fleet of vehicles with battery systems.
Vehicles are in operation under the direction of a fleet management system. Vehicles are in operation at multiple locations. At one location the duty to be performed by the vehicles is demanding and requires more energy to be used.
Routes and battery usage are predictable and are normally set up for efficient use of battery modules; e.g., battery packs with new (highest-capacity) battery modules are installed in vehicles with most demanding routes. As battery modules are used the effects of age and use reduce the capacity and other performance characteristics of the battery modules.
In operation according to an exemplary embodiment, the management system will transfer battery modules from one location to the other location so that the battery system in the vehicles of the fleet of vehicles based at the location where the duty to be performed is more demanding each have installed higher-capacity/newer battery modules. Later in life-cycle the battery modules are used in the battery system of vehicles in the fleet of vehicles at the location where the duty to be performed is not as demanding.
In operation according to an exemplary embodiment, the system provides that recommended plan for a fleet is to assign highest-capacity battery packs (e.g. with new battery modules) to more vehicles in operation in more demanding duty stations. Use of battery modules is monitored regularly and as battery modules age and have reduced capacity/performance the battery modules are transferred for installation in other vehicles in the fleet that perform standard duty.
Additional inventory of new high-capacity battery modules is ordered from regional center as needed; failed battery modules are designated in life-cycle management system and reconditioned or recycled.
Actual use and performance data will be provided to a database and data center for data analytics. Data models for battery module types will be updated to reflect actual performance data in the demanding route/weather conditions. Data will be shared with subscribers including other fleet managers and component/vehicle producers.
Example F—Single Vehicle Use/Management (Deterministic) (Alternative)
Data sources make data available to the vehicle as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data inputs comprise predicted route (e.g. based on prior GPS history or user input) plus topographic/road information plus predicted ambient temperatures (cold weather) plus battery capacity and capacity versus discharge rate, plus battery charge state, etc.
The vehicle is a hybrid-electric vehicle (with a fuel combustion power plant and electric motors each providing propulsion for the vehicle).
Data analysis determines that the intended route has steep slopes which in cold ambient conditions will drain batteries at high rate, reducing overall capacity sufficiently to require early recharge (before end-of-route).
In operation according to an exemplary embodiment, the management system provides that recommended plan for control output is to limit maximum sustained power drain (and therefore limit uphill speed) until battery internal temperature has risen to a higher value. The system may also command the fuel combustion engine to provide power when encountering high-drain part of the route.
If battery modules are interchangeable (swappable) modules, the system may recommend or select installation of high-power batteries versus high-energy batteries. The system will provide alerts and communication to advise the user/operator to either limit total distance traveled (provide a message “refuel the fuel combustion system”) or to recharge the battery module during the day. Communications may be provided to the user/operator at a user interface in the vehicle as well as to computing devices such as a home computer, table computer and smart phones.
Actual use and performance data will be provided to a database and data center for data analytics.
Example G—Single Vehicle Use/Management (Probabilistic) (Alternative)
Data sources make data available to the vehicle as indicated in FIGS. 2A-2B, 3 and 4A-4C. Data inputs comprise predicted route, traffic prediction (e.g., heavy traffic due to a scheduled sports event at/or along the route), battery capacity and regenerative charge efficiency, battery charge state, driver habits (tendency of the operator to be impatient in traffic and use of abrupt acceleration).
The vehicle is a hybrid-electric vehicle (with a fuel combustion power plant and electric motors each providing propulsion for the vehicle).
Data analysis determines that there is a significant probability that the vehicle will be caught in stop-and-go traffic with low battery charge state at end of day; resultant in frequent heavy discharge/charge cycles at low charge will tend to decrease battery life (and use history will be recorded on data/ID tag on battery module as data record).
In operation according to an exemplary embodiment, the management system provides that recommended plan for control output (in addition to other measures, e.g., limiting maximum discharge rate) should include exceeding normally optimum recharge rate during a mid-day charging stop so that battery charge state will be higher at the end of the day. The fuel combustion engine will be used if the battery system capacity is reduced below a designated threshold value (and/or periodically for a generator to recharge the battery system).
In operation according to an exemplary embodiment, the system provides that recommended plan for configuration with interchangeable modular batteries is to select at least one module with high cycle life to accommodate stop-and-go conditions.
Actual use and performance data will be provided to a database and data center for data analytics.
