## Title
Systems and methods for powering electric vehicles using a single or multiple power cells

## Abstract

Electric vehicles such as scooters can have a first operating mode in which energy is supplied by a single electrical energy storage device and a second operating mode in which energy is supplied by multiple electrical energy storage devices. A circuit element can be included in the circuit connecting the electrical energy storage devices to a prime mover such as a traction motor. The circuit element has a first, electrically conductive, state that couples only the single electrical energy storage device to a traction motor and a second, electrically non-conductive, state that couples the multiple electrical energy storage devices to the prime mover. The transition of the circuit element from the first state to the second state can occur by irreversibly fracturing the circuit element upon installation of multiple electrical energy storage devices or by a controller transitioning the circuit element from the first state to the second state.

## Background
BACKGROUND
Technical Field
The present disclosure generally relates to vehicles using an electric prime mover or motor powered by one or more rechargeable power cells providing at least a portion of the motive force needed to propel the vehicle.
Description of the Related Art
Gasoline-electric hybrids and all electric vehicles are becoming increasingly common. Such vehicles may achieve a number of advantages over traditional internal combustion engine vehicles. For example, hybrid or electric vehicles may achieve higher fuel economy and have little or even zero tail pipe emissions. In particular, all electric vehicles may not only have zero tail pipe emissions, but may be associated with reducing the overall pollution in densely populated areas. For example, one or more renewable energy sources (e.g., solar, wind, geothermal, hydroelectric) may provide some or all of the electric power used to charge electric vehicle power cells. Also for example, generation plants that burn relatively “clean burning” fuels (e.g., natural gas) which have higher efficiency than internal combustion engines, and/or which employ pollution control or removal systems (e.g., industrial air scrubbers) which are too large, costly or expensive for use with individual vehicles may provide some or all of the electric power used to charge electric vehicle power cells.
Personal transportation vehicles such as gasoline powered scooters and/or motorbikes are ubiquitous in many places, for example in the densely populated areas found in many large cities of Asia. Such scooters and/or motorbikes tend to be relatively inexpensive to acquire, register, and maintain, particularly when compared to automobiles, cars or trucks. Cities with high numbers of combustion engine scooters and/or motorbikes also tend to suffer from high levels of air pollution leading to reduced air quality for all who live and work in the metropolitan area. When new, many combustion engine scooters and/or motorbikes provide a relatively low polluting source of personal transportation. For instance, such scooters and/or motorbikes may have higher mileage ratings than larger vehicles. Some scooters and/or motorbikes may even be equipped with basic pollution control equipment (e.g., catalytic converter). Unfortunately, factory specified emissions levels are quickly exceeded as the scooters and/or motorbikes age and either not maintained and/or as the scooters and/or motorbikes are modified by owners, for example by intentional or unintentional removal of catalytic converters. Often owners or operators of scooters and/or motorbikes lack the financial resources or the motivation to maintain their vehicles.
Air pollution and the resultant reduction in air quality have a negative effect on human health, being associated with causing or exacerbating various diseases (e.g., numerous reports tie air pollution to emphysema, asthma, pneumonia, and cystic fibrosis, as well as various cardiovascular diseases). Such diseases take large numbers of lives and severely reduce the quality of life of countless others.
BRIEF SUMMARY
The reduced emissions associated with gasoline-electric hybrid vehicles and all-electric vehicles would greatly benefit air quality in densely populated urban areas, and hence tend to improve health of large populations.
Even with the zero tail pipe emissions benefit of all-electric vehicles well understood and their ability to improve the quality of life in large urban areas appreciated, adoption of all-electric vehicles by large populations has been slow. A factor that has hindered a more widespread acceptance and use of hybrid and electric vehicles is the perception that the effective range provided by the electrical energy storage devices carried by the vehicle is limited. Electrical energy storage devices can include any device capable of storing or generating an electrical charge that can provide at least a portion of the power consumed by a vehicular prime mover. Thus, electrical energy storage devices can include batteries such as lead/acid, lithium ion, nickel cadmium, and the like. Electrical energy storage devices can also include capacitive charge storage devices such as supercapacitors or ultracapacitors. Electrical energy storage devices can also include emergent electrochemical technologies, for example fuel cell technologies using membrane or similar technologies using hydrolysis to generate an electric current.
Oftentimes, vehicles may have the ability to accept a number of electrical energy storage devices. For example, some vehicles may operate on a single electrical energy storage device when only one electrical energy storage device is coupled to the vehicle and on two or more electrical energy storage devices when a number of such devices are coupled to the vehicle. The electrical coupling between the electrical energy storage devices installed in a vehicle affects the amount of energy provided by the electrical energy storage devices to the vehicle prime mover. For example, two 12 volt, 50 ampere-hour cells may be connected in series to provide a 24 volt, 50 ampere-hour “stack.” Alternatively, two such cells connected in parallel would provide a 12 volt, 100 ampere-hour “stack.” Thus, the electrical connection between two or more electrical energy storage devices can determine whether the devices provide access to a greater quantity of power at the potential expense of vehicle range (i.e., electrical energy storage devices connected in electrical series with the prime mover) or to a greater quantity of energy/vehicle range at the potential expense of vehicle power (i.e., electrical energy storage devices connected in electrical parallel with the prime mover).
In some instances, it is advantageous to offer to those consumers having relatively light duty requirements single electrical energy storage device plans that place a vehicle in a first operating mode in which energy stored in a single electrical energy storage device is made available to one or more vehicular systems. Similarly, it is advantageous to offer to those consumers having heavier duty requirements multiple electrical energy storage device plans that place the vehicle in a second operating mode in which energy stored in the multiple electrical energy storage devices is made available to one or more vehicular systems. In at least some implementations, the coupling of the second electrical energy storage device to the vehicle can beneficially place the vehicle in the second operating mode. In at least some implementations, once placed in the second operating mode, the vehicle is precluded from entering or re-entering the first operating mode (i.e., a vehicle using two electrical energy storage devices is precluded from using only a single electrical energy storage device).
The approaches described herein may address some of the issues which have limited adoption of zero tailpipe emission technology, particularly in densely crowded cities, and in populations with limited financial resources. In particular, the approaches discussed herein address issues related to operation of vehicles powered by one or more electrical energy storage devices.
A power delivery system to deliver electric power to an electric vehicle prime mover may be summarized as including a prime mover; a circuit that electrically couples the prime mover to one or more electrical energy storage devices; and at least one circuit element having a number of operational states, including at least: a first state in which an electric vehicle is placed in a first operating mode where energy is supplied by a single electrical energy storage device to the electric vehicle prime mover; and a second state in which an electric vehicle is placed in a second operating mode where energy is supplied by a plurality of electrical energy storage devices to the electric vehicle prime mover; wherein the first state does not preclude a subsequent transition by the at least one circuit element to the second state; and wherein the second state does preclude a subsequent transition by the at least one circuit element to the first state.

The power delivery method may further include receiving at a controller communicably coupled to the at least one circuit element a signal including data indicative of a state of the at least one circuit element.
The power delivery method may further include responsive to the receipt of data indicative that the at least one circuit element has entered the second mode, selectively placing the vehicle in a first operating configuration in which at least a portion of the plurality of electrical energy storage devices are coupled in electrical series with the vehicular prime mover or in a second operating configuration in which at least a portion of the plurality of electrical energy storage devices are coupled in electrical parallel with the vehicular prime mover.

FIG. 1 shows an electric vehicle 100. In at least some implementations, the electric vehicle 100 can include a vehicle that is partially powered using electric energy stored in an electrical energy storage device (e.g., a gasoline/electric hybrid vehicle) or completely powered using electric energy stored in an electrical energy storage device (e.g., an electric vehicle). In at least some implementations, the electric vehicle 100 can include a personal transportation vehicle such as the electric scooter shown in FIG. 1.
As previously noted, combustion engine scooters and motorbikes are common in many large cities, for example in Asia, Europe and the Middle East. The ability to address performance or efficiency issues related to the use of electrical energy storage devices (e.g., secondary batteries) as the main or primary energy source for a vehicle may foster the use of all-electric scooters and motorbikes 108 in place of internal combustion engine scooters and motorbikes, thereby alleviating air pollution, as well as reducing noise.
The electric vehicle 100 includes a frame 102, wheels 104a, 104b (collectively 104), and handle bar 106 with user controls such as throttle 108, brake levers 110, turn indicators switches 112, etc., all of which may be of conventional design. The electric vehicle 100 may also include a power transmission system that operably couples a traction motor 116 to at least one of the wheels 104b. Electrical energy supplied by any number of electrical energy storage devices (two shown, 118a and 118b, collectively “electrical energy storage devices 118” and singly “electrical energy storage device 118”) can be provided to the power transmission system to drive the vehicle 100. The vehicle 100 can further include one or more control circuits 120 that control the allocation or distribution of energy from the electrical energy storage devices 118 and any number of vehicular systems. For example, between the electrical energy storage devices 118 and the prime mover 116.
The prime mover 116 may take any of a variety of forms, but typically will be a traction motor or similar permanent magnet induction motor capable of outputting sufficient power (Watts or horsepower) and torque to drive the expected load at desirable speeds and acceleration. In some instances, the prime mover 116 may be a conventional electric motor capable of operating in a drive mode, as well as operating in a regenerative braking mode. In the drive mode, the prime mover 116 consumes electrical energy to drive the wheel 104. In the regenerative braking mode, the prime mover 116 operates as a generator, producing electric current in response to rotation of the wheel 104 and produces a braking effect to slow the vehicle 100.
The electrical energy storage devices 118 powering the electric vehicle 100 may take a variety of forms, for example one or more batteries (e.g., array of battery cells); one or more super-capacitors (e.g., array of super-capacitor cells); one or more ultracapacitors (e.g., array of ultracapacitor cells), or the like. For example, the electrical energy storage devices 118 may take the form of rechargeable batteries (i.e., secondary cells or batteries). Rechargeable batteries may include any current or future developed energy storage device including, but not limited to, lead/acid storage cells, nickel/cadmium storage cells, lithium ion storage cells, thin film lithium storage cells, nickel/metal hydride storage cells, and the like. In at least some implementations, the electrical energy storage devices 118 may be sized to physically fit, and electrically power, personal transportation vehicles 100, such as scooters or motorbikes, and may be portable to allow easy replacement or exchange. Given the relatively high demands imposed by many transportation applications, the electrical energy storage devices 118 are likely to take the form of one or more secondary (i.e., rechargeable) chemical battery cells.
The electrical energy storage devices 118 may include a number of electrical lugs, spades, contacts, and/or terminals (two illustrated, 122a, 122b, collectively “terminals 122”), accessible from an exterior of the electrical energy storage device 118. In at least some implementations, a displaceable slide or door that is closed to prevent inadvertent contact with either or both terminals while the electrical energy storage device 118 is removed from the vehicle 100 can cover all or a portion of the terminals 122. The terminals 122 provide the electrical contacts allowing the delivery of energy from the electrical energy storage devices 118 when the electrical energy storage device discharges. The terminals 122 also provide the electrical contacts allowing the delivery of energy to the electrical energy storage device 118 when the electrical energy storage device charges.
While illustrated in FIG. 1 as posts, the terminals 122 may take any other form accessible from an exterior of the electrical energy storage device 118, including terminals 122 positioned within slots in the electrical energy storage device housing. In at least some implementations, the terminals 122 may be disposed in recesses such as cups or slots within the exterior of the electrical energy storage device 118 to reduce the likelihood of an accidental shorting of the electrical terminals 122 during handling.
As better illustrated and described below, the control circuit 120 includes various components for transforming, conditioning and controlling the distribution and flow of electrical energy from one or more electrical energy storage devices 118 to the various vehicular systems included on on-board the vehicle 100. In particular, the control circuit 120 can control the flow of energy between the electrical energy storage device 118 and the prime mover 116. In at least some implementations, the control circuit 120 can monitor any number of electrical energy storage device parameters including, but not limited to voltage, current, temperature, charge level, cycles, temperature, etc. of some or all of the electrical energy storage devices 118. The control circuit 120 can alter, adjust, or control the flow and/or distribution of energy from the electrical energy storage devices 118 to various vehicular systems. The control circuit 120 can perform such energy distribution in a defined manner that is responsive to the one or more measured or sensed electrical energy storage device parameters.
One or more switching devices 124 are disposed in, on, or about the vehicle 100. The one or more switching devices can include any current or future developed device capable of manually or automatically providing a selectable electrically continuous pathway for the flow of current therethrough or an electrically discontinuous pathway interrupting the flow of current therethrough. The one or more switching devices 124 can have at least two states. In the first state the plurality of electrical energy storage devices 118 are placed in a first operating configuration in which some or all of the electrical energy storage devices 118 are coupled in an electrical series configuration with the prime mover 116. When the one or more switching devices 124 are in the second state the plurality of electrical energy storage devices 118 are placed in a second operating configuration in which some or all of the electrical energy storage devices 118 are coupled in an electrical parallel configuration with the prime mover 116.
In at least some instances, the one or more switching devices 124 can include one or more manual switches, such as one or more selector or toggle switches. In other instances, the one or more switching devices 124 can include one or more electrical or electromechanical switches, such as one or more relays. In yet other instances, the one or more switching devices 124 can include one or more semiconductor switches, such as one or more insulated gate bipolar transistors (IGBTs).
One or more circuit elements 130 may be disposed in the circuit electrically coupling some or all of the electrical energy storage devices 118 to the prime mover 116. In at least some instances, the one or more circuit elements 130 include one or more frangible or otherwise physically disruptable switching devices, systems, and/or elements. An example of such a frangible or physically disruptable switching device includes an electrical shunt that enters in a non-conductive electrical state upon coupling the second electrical energy storage device 118 to the vehicle 100. In other instances, the one or more circuit elements 130 can include a number of mechanical, electrical, electronic, or electromechanical switching devices, systems, and/or elements. In yet other instances, the one or more circuit elements 130 include one or more solid-state or semiconductor electrical switching devices, systems, and/or elements.
FIG. 2 shows the portions of the electric vehicle 100, according to one illustrated embodiment. As illustrated, the prime mover 116 can be operably coupled to a power transmission device such as a shaft 202, which is operably coupled either directly or indirectly to drive at least one wheel 104b of the electric vehicle 100. Although FIG. 2 depicts an example shaft 202, other types of power transmission devices such as belts and sheaves or chains and sprockets are possible.
The control circuit 120 may take any of a large variety of forms, and will typically include a controller 204, one or more power converters 206a-206d (four illustrated), and/or sensors STB, SVB, SIB, STC, SVC, SIC, STM, SVM, SIM, SRM.
As illustrated in FIG. 2, the control circuit 120 may include a first DC/DC power converter 206a that in a drive mode or configuration supplies energy from the electrical energy storage device 118 to the prime mover 116. The first DC/DC power converter 206a may step up a voltage of electrical energy from the electrical energy storage device 118 to a level sufficient to drive the prime mover 116. The first DC/DC power converter 206a may take a variety of forms, for example an unregulated or a regulated switch mode power converter, which may or may not be isolated. For instance, the first DC/DC power converter 206a may take the form of a regulated boost switch mode power converter, or buck-boost switch mode power converter.
The control circuit 120 may include a DC/AC power converter 206b, commonly referred to as an inverter that in the drive mode or configuration supplies energy from the electrical energy storage device 118 to the prime mover 116 via the first DC/DC converter 206a. The DC/AC power converter 206b may invert electrical power from the first DC/DC converter 206a into an AC waveform suitable to drive the prime mover 116. The AC waveform may be single phase or multi-phase, for example two or three phase AC power. The DC/AC power converter 206b may take a variety of forms, for example an unregulated or a regulated switch mode power converter, which may or may not be isolated. For instance, the DC/AC power converter 206b may take the form of a regulated inverter.
Control signals C1, C2 supplied by the controller 204 control one or more operational aspects of the first DC/DC power converter 206a and the DC/AC power converter 206b, respectively. For example, the controller 204, or some intermediary gate drive circuitry, may supply pulse width modulated gate drive signals to control operation of switches (e.g., metal oxide semiconductor field effect transistors or MOSFETs, bipolar insulated gate transistors or IGBTs) of the first DC/DC and/or DC/AC power converters 206a, 206b. 
As further illustrated in FIG. 2, the control circuit 120 may include an AC/DC power converter 206c, commonly referred to as a rectifier that in braking or regenerative braking mode or configuration couples the prime mover 116 to supply power generated thereby to the electrical energy storage device 118. The AC/DC power converter 206c may rectify an alternating current waveform produced by the prime mover 116 to a direct current suitable for charging at least the electrical energy storage device 118. The AC/DC power converter 206c may take a variety of forms, for example a full bridge passive diode rectifier or a full bridge active transistor rectifier.
The control circuit 120 may also include a second DC/DC power converter 206d that electrically couples the prime mover 116 to the electrical energy storage device 118 via the AC/DC power converter 206c. The second DC/DC power converter 206d may step down a voltage of the electrical power generated by the prime mover 116 to a level suitable for the electrical energy storage device 118. The second DC/DC power converter 206d may take a variety of forms, for example an unregulated or regulated switch mode power converter, which may or may not be isolated. For instance, the second DC/DC power converter 206d may take the form of a regulated buck switch mode power converter, synchronous buck switch mode power converter, or buck-boost switch mode power converter.
The AC/DC power converter 206c and the second DC/DC power converter 206d are controlled via control signals C3, C4, respectively, supplied via the controller 204. For example, the controller 204, or some intermediary gate drive controller, may supply pulse width modulated gate drive signals to control operation of switches (e.g., MOSFETs, IGBTs) of the AC/DC and/or the second DC/DC power converters 206c, 206d. 
The controller 204 may take a variety of forms that may include one or more integrated circuits, integrated circuit components, analog circuits or analog circuit components. As illustrated the controller 204 includes a microcontroller 220, non-transitory computer- or processor readable memory such as a read only memory (ROM) 222 and/or random access memory (RAM) 224, and may optionally include one or more gate drive circuits 326. In at least some implementations, one or more circuits communicably couple the controller 204 to the circuit element 130. Such a communicable coupling provides the controller 204 with the ability to monitor the state of the circuit element 130. In some instances, such a communicable coupling provides the controller 204 with the ability to change or otherwise alter the state of a mechanical, electromechanical, electronic, solid-state, or semiconductor circuit element 130.
The microcontroller 220 executes one or more machine executable instruction sets or logic to alter, adjust, or control one or more operational aspects of the power system, and may take a variety of forms. For example, the microcontroller 220 may take the form of a microprocessor, programmed logic controller (PLC), programmable gate array (PGA) such as a field programmable gate array (FPGS), and application specific integrated circuit (ASIC), or other such microcontroller device. The ROM 222 may take any of a variety of forms capable of storing processor executable instructions and/or data to implement the control logic. The RAM 224 may take any of a variety of forms capable of temporarily retaining processor executable instructions or data. The microcontroller 220, ROM 222, RAM 224 and optionally gate drive circuit(s) 226 may be coupled by one or more buses (not shown), including power buses, instructions buses, data buses, address buses, etc. Alternatively, circuits in some instances one or more analog may implement at least a portion of the control logic.
The gate drive circuit(s) 226 may take any of a variety of forms suitable for driving switches (e.g., MOSFETs, IGBTs) of the power converters 206 via drive signals (e.g., PWM gate drive signals). While illustrated as part of the controller 204, one or more gate drive circuits may be intermediate the controller 204 and the power converters 206.
The controller 204 may receive process variable signals STB, SVB, SIB, STC, SVC, SIC, STM, SVM, SIM, SRM from one or more sensors. The controller 204, via one or more sets of control logic, may use data included in at least some of the signals as process variable input(s) useful for generating one or more control variable signal output(s) CS1-CSN. Such control variable signal output(s) CS1-CSN may be useful for controlling the energy consumption, energy distribution, and/or energy allocation to one or more vehicular systems. For example, responsive to the receipt of a process variable signal STB indicative of a temperature in an on-board electrical energy storage device 118 that exceeds a defined threshold value, the controller 204 may generate one or more control variable signal output(s) CS1-CSN. The control variable signal outputs can reduce energy demand placed on the electrical energy storage devices 118 by altering, adjusting, controlling, or limiting the energy allocated to one or more vehicular systems.

A rotational sensor positioned to sense a rotation speed of the prime mover 116 can generate and transmit the process variable signal SRM that includes data indicative of the sensed rotational speed (e.g., in revolutions per minute or “RPM”) of the prime mover 116.
As discussed herein, the controller 204 can use data provided by one or more of the process variable signals STB, SVB, SIB, STC, SVC, SIC, STM, SVM, SIM, SRM to control one or more operational aspects of one or more vehicular systems. In particular, responsive to a detected or sensed change in the electrical energy storage device temperature process variable signal that exceeds one or more defined threshold values, the controller 204 can alter, adjust or control a power consumption operational aspect of one or more vehicular systems.
For example, responsive to the receipt of data indicative of an increase in electrical energy storage device temperature, the controller 204 can generate one or more control variable output signals to reduce an operational aspect such as the power consumption of one or more vehicular systems. In some instances, such reduction in the power consumption operational aspect may be in the form of a limitation on the energy made available to the particular vehicular system. In some instances, such energy limitations and/or changes in power allocation may be in the form of a step change in which the energy made available to and/or the power consumption of the vehicular system is reduced in discrete steps dependent upon the magnitude of the deviation between the sensed electrical energy storage device temperature and one or more defined threshold values. By reducing the energy made available to and/or the power consumption of one or more vehicular systems, the load on the electrical energy storage device is decreased and consequently, the temperature of the electrical energy storage device will decrease.
In another example, responsive to the receipt of data indicative of a decrease in electrical energy storage device temperature, the controller 204 may generate one or more control variable output signals to increase the energy allocation to and/or power consumption operational aspect of one or more vehicular systems. In some instances, such an increase in the energy allocation and/or power consumption operational aspect may be in the form of a step change in which the energy made available to and/or the power consumption of the vehicular system is increased in discrete steps dependent upon the magnitude of the deviation between the sensed electrical energy storage device temperature and one or more defined threshold values. By increasing the power consumption of one or more vehicular systems, the load on the electrical energy storage device is increased and the temperature of the electrical energy storage device will increase.
In some instances, the controller 204 can alter, adjust, or otherwise control one or more aspects of the power delivery profile of the electrical energy storage devices 118 coupled to the vehicle 100 based at least in part on one or more signals received from an external source. For example, the controller 204 may receive one or more signals that cause the controller 204 to limit one or more of: a voltage delivery profile of the one or more electrical energy storage devices 118, a current delivery profile of the one or more electrical energy storage devices 118, or some combination thereof. In some instances, such may take the form of a vehicle performance profile that is logically associated with a particular user of the vehicle. In other instances, such may take the form of a subscription under which a supplier and/or distributor leases electrical energy storage devices 118 to vehicle users.
In one example, a user having a two electrical energy storage device 118 subscription may select between several performance plans. Such performance plans may include a “RANGE” plan in which the user is unable to adjust the energy flow from the electrical energy storage devices 118 to the motor (i.e., a fixed speed plan that maximizes available range). Such performance plans may include a “RANGE/PERFORMANCE” plan in which the user is able to change the electrical configuration of the batteries between a first configuration that maximizes available range and a second configuration that maximizes the available acceleration and/or velocity achievable by the vehicle 100.
The controller 204 includes either separate transmitter and receiver systems or a combined transmitter/receiver or transceiver 228. In at least some instances, the transceiver 228 may provide wired and/or wireless communications with components, systems, or devices that are remote from the scooter 100. The transceiver 228 may take a large variety of forms suitable to provide wired or wireless communications. For example, the transceiver 228 may take the form of a cellular phone chipset (also referred as a radio) and antenna(s) to carry on communications with a remote system via a cellular service provider network. The transceiver 228 may implement wireless communications approaches other than cellular based communications. Communications may include receiving information and/or instructions from a remote system or device, as well as transmitting information and/or instructions or queries to a remote system or device.
In at least some instances, the transceiver 228 may include one or more devices capable of communicably coupling with a cellular communications device (e.g., a cell phone or smartphone) carried by a user. Examples of such devices include, but are not limited to any current or future developed radio frequency communications devices such as Bluetooth® devices, near field communications (NFC) devices, and the like. In at least some instances, the transceiver 228 can communicably couple to one or more external systems or devices via a Bluetooth or NFC connection to a cellular device carried by the user.
The controller 204 may include a global positioning system (GPS) receiver 230, which receives signals from GPS satellites allowing the controller 204 to determine a current location of the scooter 100. In at least some implementations, the GPS receiver 230 may include a GPS chipset without provision of a user display on the scooter 100. Any of a large variety of commercially available GPS receivers may be employed. The present location or position may be specified in coordinates, for example a longitude and latitude that is accurate to within 3 meters. Alternatively, other techniques may be employed for determining the present location or position of the scooter 100, for example triangulation based on three or more cellular towers or base stations.
Elevation at a present location may be discernible or determined based on the GPS coordinates. Likewise, elevation changes between a current location and one or more other locations or destinations may be determined using a topographical mapping or other structured format that relates GPS coordinates with elevations. Such may be advantageously employed in better estimating a range of the scooter 100. Alternatively, or additionally, the scooter 100 may include an altimeter that detects elevation, or other sensors, for example an accelerometer, that detects changes in elevation. Such may allow potential energy associated with a relative position of the scooter 100 with respect to hills (e.g., top of hill, bottom of hill) to be taken into account when determining an estimate range. Such may advantageously produce more accurate or estimated range, preventing unnecessary limiting of operational performance. For example, knowledge that the scooter 100 is at or proximate a top of a large hill may lead to an increase in the determined estimated range, bringing a replacement or replenishment location within the range, and preventing the need to limit operational performance. Alternatively, knowledge that the scooter 100 is at or proximate a bottom of a large hill may lead to a decrease in the determined estimated range, indicating that a nearest replacement or replenishment location is outside the estimated range, and causing the limiting of operational performance to occur earlier than otherwise, ensuring that the scooter 100 will reach the replacement or replenishment location.
FIG. 3A shows a schematic diagram of an electric vehicle 100 such as a scooter having two electrical energy storage device receivers 304a, 304b (collectively “receivers 304”), according to one illustrated embodiment. As shown in FIG. 3A, only one electrical energy storage device 118a installed in receiver 304a powers the vehicle 100. With a single electrical energy storage device 118 coupled to the vehicle 100, the vehicle is in a first mode of operation or first operating mode in which the single electrical energy storage device 118 provides energy to the prime mover 116.
Also as shown in FIG. 3A, a frangible shunt type element 302 can provide the circuit element 130. The frangible shunt type element 302 can have an electrically conductive first state in which the frangible element 302 supports the flow of current therethrough and an electrically non-conductive second state in which the frangible element 302 does not support the flow of current therethrough. In at least some implementations, insertion of a second electrical energy storage device 118b into the second electrical energy storage device receiver 304b can change, disrupt, or otherwise place the frangible element 302 in the electrically non-conductive second state. In at least some instances, a protrusion or physical feature 306 on the second receiver 304b or on the electrical energy storage device 118b can fracture the frangible element 302 thereby placing the frangible element 302 in the second, electrically non-conductive, state when the second electrical energy storage device 118b is coupled to the vehicle 100. The use of the frangible element 302 beneficially provides a simple and robust system for converting the vehicle 100 from the first operating mode to the second operating mode.
In at least some instances, the frangible element 302 can include one or more vehicle user replaceable components. For example, the frangible element 302 may include spades, lugs, or threads that permit a user to replace an electrically non-conductive frangible element 302 with an electrically conductive replacement frangible element 302. In other instances, the frangible element 302 can include one or more non-user replaceable components. For example, the frangible element 302 may include one or more components, devices, or systems requiring replacement or resetting by qualified service personnel.
One or more sets of terminals, contacts, or the like 308a, 308b, 310a, 310b (collectively “terminals 308” and “terminals 310”) may be disposed in the second electrical energy storage device receiver 304b. The terminals 308 and 310 in the second electrical energy storage device receiver 304b electrically couple the second electrical energy storage device 118b to the vehicle 100 via the terminals 122 on the second electrical energy storage device 118b. 
One or more circuits 328 communicably couple the controller 120 to the one or more switching devices 124. In at least some instances, the one or more circuits 328 communicate information between the controller 120 and the one or more switching devices 124. In at least some instances, such information may include data indicative of the position of the one or more switching devices 124. In at least some instances, such information may include data indicative of one or more control variable output signals generated by the controller 120. Using such control variable output signals, the controller 120 changes the state of the one or more switching devices 124. The controller 120 can communicate such control variable output signals to the one or more switching devices 124 via the one or more circuits 328.
FIG. 3B shows a schematic diagram of an electric vehicle 100 such as a scooter having two electrical energy storage device receivers 304a, 304b (collectively “receivers 304”), according to one illustrated embodiment. As shown in FIG. 3B, receivers 304a, 304b each contain a single electrical energy storage device 118a, 118b, respectively. Placing the second electrical energy storage device 118b in the second electrical energy storage device receiver 304b causes the physical feature 306 to fracture or otherwise place the circuit element 130 in a non-electrically conductive state. With a plurality of electrical energy storage devices 118 coupled to the vehicle 100, the vehicle is in a second mode of operation or second operating mode in which the plurality of electrical energy storage devices 118 provide energy to the prime mover 116.
In an implementation such as that depicted in FIG. 3B, the at least one switching device 124 is shown in a first state that selectively places the two electrical energy storage devices 118 in a first operating configuration in which the electrical energy storage devices 118 are in an electrical series arrangement with the prime mover 116. Such an arrangement can provide energy to the prime mover 116 for a longer duration but at a higher voltage than a parallel arrangement of the electrical energy storage devices 118 with the prime mover 116.
In at least some instances, the vehicle operator can manually place or otherwise change the state of the at least one switching device 124 to the first state to place the electrical energy storage devices 118 in electrical series with the prime mover 116. In other instances, the controller 120 can autonomously place or otherwise position the at least one switching device 124 in the first state to place the electrical energy storage devices 118 in electrical series with the prime mover 116. Placing the at least one switching device 124 in the first state may increase one or more vehicle performance characteristics, such as the torque and/or power developed by prime mover 116.
FIG. 3C shows a schematic diagram of an electric vehicle 100 such as a scooter having two electrical energy storage device receivers 304, according to one illustrated embodiment. As shown in FIG. 3C, receivers 304a, 304b each contain a single electrical energy storage device 118a, 118b, respectively. Placing the second electrical energy storage device 118b in the second electrical energy storage device receiver 304b causes the fracture or placement of the circuit element 130 into a non-electrically conductive state. Responsive to coupling the plurality of electrical energy storage devices 118 to the vehicle 100, the vehicle is placed in a second mode of operation or second operating mode in which the plurality of electrical energy storage devices 118 provide energy to the prime mover 116.
In an implementation such as that depicted in FIG. 3C, the at least one switching device 124 is shown in a second state that selectively places the two electrical energy storage devices 118 in a second operating configuration in which the electrical energy storage devices 118 are in an electrical parallel arrangement with the prime mover 116. Such an arrangement can provide energy to the prime mover 116 at a lower voltage but for a longer duration than a serial arrangement of the electrical energy storage devices 118 with the prime mover 116.
In at least some instances, the vehicle operator can manually place or otherwise change the state of the at least one switching device 124 to the second state to place the electrical energy storage devices 118 in electrical parallel with the prime mover 116. In other instances, the controller 120 can autonomously place or otherwise position the at least one switching device 124 in the second state to place the electrical energy storage devices 118 in electrical parallel with the prime mover 116. Such an autonomous adjustment may be made by the controller 120 to increase the operating range of the vehicle 100 in response to a detected low remaining charge in one or more electrical energy storage devices 118.
FIG. 4 shows a schematic diagram of an electric vehicle 100 such as a scooter having two electrical energy storage device receivers 304a, 304b (collectively “receivers 304”), according to one illustrated embodiment. As shown in FIG. 4, receivers 304a, 304b each contain a single electrical energy storage device 118a, 118b, respectively. Also as shown in FIG. 4, a mechanical, electromechanical, electronic, or semiconductor switch (“switching device 402”) can provide the circuit element 130 in lieu of the frangible shunt type circuit element 130 depicted in FIGS. 3A-3C.
The use of the switching device 402 beneficially provides the ability to reset the vehicle 100 from the second operating mode (i.e., a two electrical energy storage device mode) to the first operating mode (i.e., a one electrical energy storage device mode) without requiring the physical replacement or restoration of the circuit element 130. In some instances, the vehicle operator can reset the operating mode of the vehicle 100, for example by providing a defined code or password to the controller 120. In some instances, one or more remote devices (e.g., one or more backend systems communicably coupled to the vehicle 100, the electrical energy storage device 118, or similar vehicular components) can reset the operating mode of the vehicle by changing the state of the circuit element 130. In one example, the backend system can wirelessly communicate (e.g., via a smartphone communicably coupled to the vehicle 100, or directly via GSM or CDMA to the transceiver 228 in the vehicle 100) one or more commands or executable instruction sets to the controller 120 that cause the controller 120 to transition the circuit element from the second state to the first state. In another example, a nontransitory storage media communicably coupled to the vehicle 100 can store one or more commands or executable instruction sets provided by the backend system that cause the controller 120 to transition the circuit element from the second state to the first state.
In at least some instances, the switching device 402 can include one or more mechanical switches. For example, the switching device 402 can include a single-pole, single-throw (“SPST”) selector or toggle switch having a first, electrically continuous, state and a second, electrically discontinuous, state. In some instances, the mechanical switch can include an integrated lock or other feature that prevents an unintended transition from the first state to the second state. In other instances, the mechanical switch can include one or more actuators capable of positioning the switch in the first and second states. In such instances, the controller 120 can automatically control the position of the mechanical switch using electrical signals communicated to the actuator via the one or more circuits 326.
In other instances, the switching device 402 can include one or more electromechanical switches. For example, the switching device 402 can include one or more solenoid actuated relays having a first, electrically continuous, state and a second, electrically discontinuous, state. In at least some instances, the state of the electromechanical switch can change based on the presence or absence of an electrical current flowing through the solenoid. In some instances, the vehicle operator can manually control the electrical current supplied to the pilot solenoid. In other instances, the controller 120 can automatically control the electrical current supplied to the pilot solenoid via the one or more circuits 326.
In yet other instances, the switching device 402 can include one or more semiconductor switches. For example, the switching device 402 can include one or more transistors such as an insulated gate bipolar transistor (“IGBT”). In at least some instances, the controller 120 can automatically control the electrical the state of the semiconductor switch via the one or more circuits 326.
