Electric vehicles rely on one or more electrical energy storage devices to provide power and provide power to some or all of the vehicle systems, such as electric bicycles. The electrical energy storage device can have a plurality of thermal sensors that provide information indicative of the overall and/or local electrical energy storage device temperature to the controller. In order to maintain the electrical energy storage device in the desired thermal operating range or distribution, the controller can selectively change or control the power distributed or distributed to one or more vehicle systems. The controller can make this change or control of the power distribution based on the assessed vehicle system criticality.
Electric energy storage device heat distribution adjustment controller, method and electric vehicle system thereof
The present disclosure is directed to a vehicle that uses an electric prime mover or motor that drives the electric prime mover or motor by providing at least one chargeable power cell with at least a portion of the power required to propel the vehicle.
Hybrid and electric vehicles have become more common. This vehicle can achieve some advantages over conventional internal combustion engine vehicles. For example, a hybrid or electric vehicle can be more fuel efficient and has only a little or no tailpipe emissions. In particular, all electric vehicles not only have zero tailpipe emissions, but also reduce overall pollution in densely populated areas. For example, one or more renewable energy sources (eg, solar, wind, geothermal, hydro) may provide some or all of the electrical utilization to charge an electric vehicle power cell. Similarly, for example, a power plant that burns relative to "completely combusting" fuel (eg, natural gas) is more efficient than an internal combustion engine and/or uses a pollution control or removal system (eg, an industrial air scrubber) that provides some Or all of the power is used to charge the electric vehicle power battery, and for individual vehicles, the pollution control or removal system is too large or expensive.
Personal transport vehicles, such as gasoline-powered treadmills and/or motorcycles, are ubiquitous in many places, such as densely populated areas in many large cities in Asia. particular Compared to automatic cars, cars or trucks, the acquisition, registration and maintenance of these treadmills and/or motorcycles are becoming less expensive. Cities with many internal combustion engine treadmills and/or motorcycles are also increasingly exposed to severe air pollution, resulting in a decline in air quality for people living and working in metropolitan areas. Many new internal combustion engine treadmills and/or motorcycles provide personal transportation with relatively low pollution sources. For example, these treadmills and/or motorcycles may have a higher mileage rating than larger vehicles. Some treadmills and/or motorcycles may even have basic pollution control devices (eg, catalytic converters). Unfortunately, when the treadmill and/or the motorcycle is old and unmaintained and/or when the owner modifies the treadmill and/or the motorcycle, for example intentionally or unintentionally removing the catalytic converter, it quickly overtakes the factory. Specific emissions. Typically, the owner or operator of a motorcycle and/or motorcycle lacks the source of money or the power to maintain its vehicle.
Air pollution and the resulting deterioration in air quality have a negative impact on human health, causing various diseases (for example, many reports of air pollution and emphysema, asthma, pneumonia and cystic fibrosis, and various cardiovascular diseases) or The disease is getting worse. These diseases take many lives and seriously reduce the quality of life of countless lives.
The reduction of emissions from hybrid electric vehicles and all-electric vehicles is very helpful in air quality in densely populated areas and thus improves the health of a large population.
Even though the advantages of zero-tail tube emissions from all-electric vehicles and their improved quality of life in many urban areas have been well understood, the adoption of all-electric vehicles for a large population is still slow. One of the reasons hindering greater acceptance and the use of hybrid and electric vehicles is that the range of effectiveness provided by the electrical energy storage devices carried by the vehicle is limited. The electrical energy storage device can include any device that can store or generate electrical charge that can provide at least a portion of the power consumed by the vehicle's prime mover. Thus, the electrical energy storage device can include batteries such as lead/acid, lithium ion, nickel cadmium, and the like. The electrical energy storage device may also include a capacitive charging storage device, such as a super battery Container or ultra high capacitor. The electrical energy storage device can also include emergency electrochemical techniques, such as fuel cell technology using membranes or similar techniques using hydrolysis to generate electrical current.
Electrical energy storage devices typically include batteries that are coupled in series and/or in parallel to provide the desired storage capacity and delivery voltage. For example, two 12 volt, 50 amp-hour batteries can be connected in series to provide a "stack" of 24 volts, 50 amp-hours. Four such stacks can be connected in parallel to provide an electrical energy storage device with a 24 volt output and a 200 amp-hour capacitor. While manufacturers of electrical energy storage devices are committed to making each battery the same "standard," the variation between voltage and capacitance of each battery is inevitable. In this example, a battery having a relatively low voltage or relatively low capacitance can serve as the "weakest link" in the storage device, limiting the available power delivered by the electrical energy storage device.
In addition, most electrical energy storage devices rely on some form of reversible electrochemical reaction to generate current in a discharged state and to accept current in a charged state. Many such electrochemical reactions are exothermic and release thermal energy equivalent to or proportional to the current produced by the electrical energy storage device. In order to protect an electrical energy storage device from physical damage, theft, and environmental conditions that are unfavorable, such as in rainy tropical and subtropical environments, the electrical energy storage device carried by the vehicle is typically partially or completely covered by the housing. When a physical and environmental protection is provided, the coated housing captures at least a portion of the thermal energy released during the electrical energy storage device discharge, resulting in a rapid and significant increase in the internal and/or external temperature of the electrical energy storage device. In many metropolitan areas, high temperature environmental conditions can exacerbate this thermal growth.
Many states can adversely affect the performance of the electrical energy storage device, such as the amount of current being charged, the temperature and history of use, including the number of years the primary electrical energy storage device has been used and the number of recharge cycles. The range can also vary based on many other factors or states. For example, vehicle related conditions may affect range, such as size, weight, torque, top speed, and drag coefficient. Likewise, for example, the driving or operator status can affect the range, such as whether the driver or operator is driving at a high speed or rapid acceleration (i.e., violent acceleration). Furthermore, for example, environmental conditions can affect ranges such as ambient temperature and terrain (eg, flat, mound Mausoleum).
The power available to electrical energy storage devices typically decreases with temperature. Thus, a vehicle powered by an electrical energy storage device and operating at a higher ambient temperature has a range that is less than the same vehicle operating in the same manner at a lower ambient temperature using the same electrical storage device. Compared to surrounding batteries, these weakened cells typically deplete faster and produce larger heat output by-products, which is more important when the electrical energy storage device contains one or more weakened cells. In the first step of promoting the popularization of electric vehicles, it is important to confirm an appropriate and predictable range. This is especially true when it is possible to replace or supplement a primary power or electrical energy storage device, assuming that the vehicle can reach a replacement or supplemental location.
The methods described here can address some of the problems of limiting the use of zero tailpipe emissions technologies, particularly in densely populated cities and populations with limited financial resources. In particular, the methods discussed herein deal with problems with thermal monitoring of electrical energy storage devices and adjustment of one or more operational parameters of one or more vehicle systems.
For example, some of the methods described herein may limit vehicle operation (eg, speed, acceleration), effectively increasing the operating range of the vehicle in response to thermal distribution of the electrical energy storage device, which is indicative of reduced charge capacity or power transfer. In addition, the operation of electric vehicle equipment (eg, air conditioning, heating, defrost, lighting, sound systems, power windows, electric locks, seat heaters, global positioning systems, wireless communication systems, and the like) may be compromised or The operating range of the vehicle is increased in response to a thermal storage of the electrical energy storage device indicating a reduced amount of charge or power transfer.
The operation of one or more vehicle systems is compromised or limited based on the heat distribution of the electrical energy storage device providing the vehicle electrical power, providing an opportunity for the operator to use the remaining stored energy to reach a location where the electrical energy storage device is available. In one example, the controller can control operation of one or more power converters to limit current and/or voltage supplied to the power motor of the vehicle or vehicle accessory to confirm that power is reached for charging the current electrical energy storage device Supply position Enough range. In another example, the controller can control operation of one or more power converters to limit current and/or voltage supplied to the power motor of the vehicle or vehicle accessory for confirmation of replacement for the current electrical energy storage device. There is a sufficient range to replace the power supply location.
In at least some examples, reducing the temperature of the electrical energy storage device causes the vehicle prime mover to obtain additional energy. Additional energy obtained by varying the heat distribution of the electrical energy storage device can be distributed or distributed to one or more vehicle systems. This use may include, but is not limited to, changing the torque/power curve of the prime mover to provide enhanced vehicle performance, enabling one or more systems, and the like.

In at least some examples, control variable signal output 406 can change the power consumption of one or more safety critical systems 410, performance critical systems 412, range critical systems 414, and/or non-critical systems 416. In some examples, the power consumption adjustment can be performed by controller 304 to maintain one or more temperatures in electrical energy storage device 118 within a desired operating range, which maximizes the range available for electrical energy storage device 118. Chemical.
The need for each of the safety critical system 410, the performance critical system 412, the range critical system 414, and/or the non-critical system 416 for the electrical energy storage device 118 is cumulative. Since the temperature level of the electrical energy storage device 118 depends on the temperature of the storage battery 202, the ideal temperature range exists for the maximum power delivered by the electrical energy storage device 118. The controller 304 can control the temperature of the electrical energy storage device 118 by changing the demand of the vehicle system for the electrical energy storage device 118. In at least some embodiments, controller 304 can adjust or down regulate the power consumption of one or more vehicle systems in a series of step changes, resulting in a corresponding upward or downward change in temperature in electrical energy storage device 118. In this manner, the controller 304 can compensate various states of the interior and exterior of the electrical energy storage device 118 while maintaining the temperature of the electrical energy storage device 118 within a defined preferred temperature range for storage in the electrical energy storage device 118. The maximum energy possible.
In at least some examples, controller 304 can change, control, adjust, or vary electrical energy storage devices based on at least partial assessment of whether the vehicle system is safety critical system 410, performance critical system 412, range critical system 414, and/or non-critical system 416 118 provides energy to one or more vehicle systems. For example, in response to the detected increase in temperature of the electrical energy storage device, controller 304 may adjust the power consumption of the vehicle system downwardly in the following order: first, non-critical system 416; second, performance critical system 412; third, range Critical system 414; and finally, safety critical system 410. In another example, in response to the detected temperature drop of the electrical energy storage device 118, the controller 304 can adjust the power consumption of the vehicle system upwards in the following order: first, the safety critical system 410; second, the range critical system 414; Third, the performance critical system 412; and finally, the non-critical system 416.
Safety critical system 410 may include, but is not limited to, any vehicle system associated with the safety of the vehicle user or occupant, as well as vehicle systems that are required to comply with local, regional, or federal regulations.

Residual Vehicle Range For example, the system can include a regenerative braking system and a power converter for providing charging current to the electrical energy storage device 118.
Non-critical systems 416 may include, but are not limited to, any vehicle system that does not belong to the other three systems. For example, such systems may include, but are not limited to, entertainment systems, non-standard lights, and the like.
In at least some examples, is the specific system critical or critical? The assessment of the nature, scope, or non-criticality may be in the form of a state assessment by controller 304. For example, during the daytime, the status assessment of controller 304 may determine that no headlights are needed and are therefore non-critical; however, at night or when visibility is reduced, headlamps are necessary for user safety or compliance. Likewise, when there is an environmental deposit, the state assessment of the controller 304 can determine that the windshield wiper is safety critical; however, when there is no environmental deposit, the windshield wiper is considered non-critical. In at least some examples, the state assessment of controller 304 can be based on the overall or partial information and/or environmental data directly obtained by controller 304 (eg, by using the sensor being used). In other examples, the state assessment of controller 304 may be based on controller 304 (eg, by using one or more external systems or devices communicatively coupled to provide one or more external systems or devices) to provide overall or partial information and/or Environmental information.
In at least some embodiments, to reduce current flow from the electrical energy storage device 118, the controller 304 can selectively reduce the energy available to one or more non-critical, range critical or performance critical vehicle systems. Generally, reducing the current from the electrical energy storage device 118 reduces the heating of the electrical energy storage device 118. In at least some embodiments, reducing the temperature of the electrical energy storage device 118 can increase the energy available for storage in the electrical energy storage device 118.
In an embodiment, the controller 304 can gradually reduce the energy available to the vehicle system. For example, controller 304 may use a fixed ratio of loads (eg, a non-critical vehicle system that presents 100 watts (W) may be reduced by 10 W per step to 90 W, 80 W, etc.) while controlling or limiting one or more non-critical, range critical Or the energy available to a critical vehicle system. In some examples, controller 304 may selectively disable non-critical, range critical or performance critical vehicle systems, rather than having the system gain energy to compromise or compromise the performance, reliability or longevity of the vehicle system. For example, if the power available to the system is reduced to less than 60 W, the above non-critical 100 W load may be damaged. In this example, controller 304 can simply invalidate the non-critical vehicle system, rather than reducing power to less than 60W.
In an embodiment, the controller 304 is selectable based on the needs presented by the system. The energy provided to one or more vehicle systems is reduced. This power reduction mode can advantageously minimize the amount of energy from the electrical energy storage device 118 while limiting the impact of the reduction on the minimum number of vehicle systems. For example, if five non-critical systems present loads of 100w, 80W, 60W, 40W, and 20W, the controller 304 selectively steps down the energy available to the system that presents the maximum load to the electrical energy storage device 118 (ie, selectivity). Ground the 100W load to 80W). Between the two or more systems that present the maximum load to the electrical energy storage device 118, the controller 304 can share the subsequent reduction in energy available to the vehicle system (ie, the reduction in the two 80W load systems is the same as 60W), And so on.
In at least some embodiments, some or all of the thermal data collected by thermal sensor 210 can be stored in the form of heat distribution 430 in non-transitory storage device 220. Additionally, an instant clock or similar timer internal or external to the electrical energy storage device 118 can provide information representative of the date stored in each of the temperature readings in the non-transitory storage device 220. Moreover, the geographic coordinates of the electric vehicle 100 generated or provided by a global positioning system (GPS) network or other terrestrial geographic location or triangulation network and/or system can be logically stored with each of the non-transitory storage devices 220. A temperature read value is associated. In some examples, controller 304 provides all or part of the date information. Additionally, parameter data representative of operational parameters of one or more vehicle systems may also be stored in non-transitory storage device 220 in the form of thermal performance profile 432, which in at least some instances may be logically non-reproducible Some or all of the temperature data stored in the temporary storage medium is associated. In a typical operating state, the logical association of vehicle parameter data with the thermal state in electrical energy storage device 118 can provide an important insight into electrical energy storage device 118. The logical association of the vehicle profile data with the thermal state in the electrical energy storage device 118 provides an important insight into the electrical energy storage device 118 for each user. The thermal distribution of the electrical energy storage device 118 is associated with a particular user, based on at least a portion of the assessment, providing the ability of a particular user to sell products and services. Associating the thermal distribution of the electrical energy storage device 118 with a particular user, based on at least a portion of the assessment, provides the ability for a particular user to provide rental conditions for the electrical energy storage device 118.
FIG. 5 illustrates an environment including a station, rack or kiosk 502 that replaces the depleted electrical energy storage device 118 with an inventory 504 of an at least partially charged electrical energy storage device. In at least some embodiments, the kiosk 502 is communicatively coupled 510 to one or more backend systems 530 via one or more networks 520.
Although FIG. 5 only depicts kiosk 502, for example, a geographic area of a city or town, or another area of a county, may include any number of kiosks 502. The kiosk 502 can automatically collect, charge, and distribute the electrical energy storage device 118. Alternatively, the individual can operate the kiosk 502 while manually collecting, charging, and distributing the electrical energy storage device 118. Typically, each kiosk 502 retains an inventory of energy or power storage devices 504 for various states of charge and/or conditions. The kiosk 502 provides an exchange point, and the user can replace the discharged or depleted electrical energy storage device 118 with a fully charged electrical energy storage device 118. The network of the kiosk 502 can advantageously increase the user's confidence in the reliability and availability of an electric vehicle, such as an electric vehicle 100 or a similar electric vehicle. By increasing the user's confidence in the reliability of the electric vehicle, it is advantageous to increase the acceptance of such vehicles.
Environment 500 includes one or more backend systems 530 that include one or more backend servers 532a (only one shown) that are used to track kiosks 502 that can replace or supplement electrical energy storage devices 118. The backend system 530 includes non-transitory media 534 (e.g., a hard drive) that retains a repository or other repository 536 of various kiosks 502. This information may include geographic coordinates of various kiosks 502, such as expressed in longitude and latitude and/or in street addresses. This information may also include the current inventory 504 of the electrical energy storage device 118 stocked in each kiosk 502. In some examples, database 536 can include data indicative of the number of electrical energy storage devices 118 available at a particular kiosk 502. In some examples, database 536 can include information indicative of the state of charge of electrical energy storage device 118 available at a particular kiosk 502.
In some examples, database 536 can include information indicative of heat distribution 430 or thermal performance profile 432 of electrical energy storage device 118 available at a particular kiosk 502. It is important that the availability of the heat distribution 430 information can advantageously cause the kiosk 502 and/or the backend system 530 to recognize electrical energy. An electrical energy storage device 118 with a reduced amount of storage. By identifying the electrical energy storage device 118 with impaired electrical energy storage, one or more privileges (eg, a rental discount, a free "rental" or other cash or promotional offer) may be provided to the user of the damaged device. Thus, the acceptance of the trading environment of the electrical energy storage device 118 is improved (i.e., by changing the value of the damaged electrical energy storage device, the value of the user receiving the damaged electrical energy storage device is improved).
In other examples, the heat distribution 430 or thermal performance profile 432 stored in the backend system 530 can be used to evaluate individual vehicle operating habits. This assessment may cause the backend system 530 to generate user-specific promotions and offers based on how the user operates the vehicle in a "real world" situation. For example, the user may prefer full throttle activation (ie, high speed start), causing the electrical energy storage device 118 to run out of high current. In an operating environment (ie, an urban environment) in which multiple such activations are unavoidable, the user may receive a promotional offer for the second electrical energy storage device after the kiosk 502 replaces the discharged electrical energy storage device. Alternatively, if the full throttle activation is found to be detrimental to the expected life of the electrical energy storage device 118, based on driving habits, the user may have to pay a higher rental cost to reflect the shortened life expectancy of the electrical energy storage device 118.
Environment 500 can include a communication infrastructure or network 520 that facilitates communication between various components, such as various kiosks 502 and/or one or more electric vehicles in which back-end system 530 and switching, replacing, or supplementing electrical energy storage device 118 are located. Between 100. Network 520 can take a variety of forms and can include various components and systems, such as wired or fiber optic components or systems and/or wireless components or systems. For example, network 520 can include a cellular communication network provided by a cellular service provider with a base station. This may enable data communication over the wireless infrastructure, such as communicating with the electric vehicle 100. Some of these components are communicatively coupled to a wired network, such as a traditional telephone service (POTS) network. In at least some examples, fixed elements such as backend system 530 and a plurality of kiosks 502 can be communicatively coupled via conventional telephone lines. Alternatively, the backend system 530 and the plurality of kiosks 502 can be connected via the Internet or other network. (e.g., an external network, an internal network) communicatively coupled, the network may use a combination of wired, wireless, and/or wired and wireless communication paths or channels.
FIG. 6 illustrates a thermal compensation method 600 in accordance with one or more embodiments. Since the electric vehicle 100 is powered by the electrical energy storage device 118, the temperature of the electrical energy storage device 118 will rise. If there is a weak or damaged storage battery 202 in the electrical energy storage device 118, this heating will raise the temperature of the entire electrical energy storage device 118. This heating is at least partially related to the current demand of the various vehicle systems coupled to the electrical energy storage device 118. If there is a weak or damaged storage battery 202 in the electrical energy storage device, in addition to the overall temperature rise of the electrical energy storage device 118, the local temperature increase will be greater than the overall electrical energy storage device 118 in the vicinity of the weak or damaged storage battery 202. The temperature increases. In at least some examples, the network of thermal sensors 210 can be located throughout the electrical energy storage device to detect an increase in the temperature of the electrical energy storage device as a whole and any localized heating that occurs in the electrical energy storage device 118. The method 600 begins at step 602.
At step 604, the temperature of the electrical energy storage device 118 is measured using any number of thermal sensors 210. These thermal sensors 210 measure any number of individual or point temperatures that represent the overall temperature of the electrical energy storage device 118 and/or the local temperature of the individual electrical energy storage cells, locations, points, zones or regions that are different within the electrical energy storage device 118. . One or more algorithms can be used to combine or analyze data representative of the measured temperature. For example, some or all of the measured points or individual temperatures may provide an overall electrical energy storage device 118 temperature. In another example, the measured temperatures of some of the thermal sensors proximate to one or more of the storage cells 202 or the storage battery stack 204 can be combined to provide a heat distribution for the location, point, zone or region, corresponding to one Or the temperature of multiple batteries or battery stacks.
At step 606, controller 304 determines one or more first differences between the measured temperature and the defined threshold. In at least some embodiments, the first difference can be determined using data indicative of one or more measured or determined temperatures in the electrical energy storage device 118 and one or more individually defined thresholds. In at least some embodiments, the one or more defined thresholds are All or part of it is stored in non-transient read only memory 322 and/or non-transitory random access memory 324.
In step 608, controller 304 generates control variable signal output 406 based at least in part on the first difference determined at step 606. Controller 304 generates a control variable signal output 406 using a defined control algorithm to limit the first difference to an acceptable range. In at least some examples, the control algorithm can include proportional control, integral control, differential control, or a combination thereof. In some examples, this control algorithm may include time constants and other factors to improve the responsiveness of controller 304.
At step 610, controller 304 communicates control variable signal output 406 to at least one vehicle system. Control variable signal output 406 causes power consumption adjustment of the at least one vehicle system. The current demand for the electrical energy storage device 118 and the heat output of the electrical energy storage device 118 are reduced by reducing the power consumption of the at least one vehicle system. The method 600 ends at step 612.
FIG. 7 illustrates a thermal compensation method 700 that is based on a rate of temperature change in electrical energy storage device 118, in accordance with one or more embodiments. Generally, as shown in FIG. 6 and above, as the current demand for the electrical energy storage device 118 increases, the temperature of the electrical energy storage device 118 is readily increased. When this current demand is relatively constant, the temperature slowly increases throughout the process. When the current demand is intermittently large (for example, in response to fast, full throttle, and current demand due to acceleration), the temperature increases rapidly throughout the process. Thus, although an increase of 5 °C for 20 minutes is an acceptable increase based on constant current demand, in terms of the charge availability retained in the critical electrical energy storage device 118, it is not possible to rise by the same 5 ° C in a one minute interval. accept. Thus, in some examples, the rate of temperature change (eg, C or degree F per time interval) may provide another insight into the charge retentivity retained in the electrical energy storage device 118.
In at least some embodiments, method 700 can be combined with method 600 described above to provide a control method in response to changes in electrical energy storage device temperature and electrical energy storage device 118 The rate at which the temperature changes. The method begins in step 702.
At step 704, the controller 304 determines the rate of temperature change of some of the thermal sensors 210 in the electrical energy storage device 118. These thermal sensors 210 measure the rate of temperature change for any number of individual or point temperatures that represent the overall temperature of the electrical energy storage device 118 and/or different individual electrical energy storage batteries, locations within the electrical energy storage device 118. The local temperature of a point, zone or zone. Controller 304 may combine or analyze data representative of the measured rate of temperature change using one or more defined algorithms, which are controller readable, machine executable code. For example, an average of some or all of the measured points or individual temperature change rates may provide a rate of temperature change for the overall electrical energy storage device 118. In another example, the measured rate of temperature change of one or more of the storage cells 202 or some of the thermal sensors that store the battery stack 204 can be combined to provide a battery or stack temperature change rate.
At step 706, controller 304 determines one or more second differences, and in at least some embodiments, data indicative of a rate of temperature change indicative of one or more determinations in electrical energy storage device 118 and one or more individually defined The threshold is determined and the second difference is determined. In at least some embodiments, the one or more defined thresholds may be stored in whole or in part in non-transient read only memory 322 and/or non-transitory random access memory 324.
At step 708, controller 304 generates control variable signal output 406 based at least in part on the second difference determined at step 706. Controller 304 generates a control variable signal output 406 using a defined control algorithm to limit the second difference to an acceptable range. In at least some examples, the control algorithm can include proportional control, integral control, differential control, or a combination thereof. In some examples, this control algorithm may include time constants and other factors to improve the responsiveness of controller 304. The method 700 ends at step 710.
FIG. 8 illustrates a thermal compensation method 800 in which controller 304 measures power consumption and assesses the criticality of the vehicle system. In electric vehicles or hybrid vehicles, various vehicle systems have current (or power) requirements for the electrical energy storage device 118. In order to control the electrical energy storage device 118 Temperature or rate of temperature change For various vehicle load, controller 304 must: (a) know which vehicle system is being operated; (b) determine the power consumption of each operating vehicle system; and (c) evaluate each vehicle system Critical. The method begins in step 802.
At step 804, controller 304 determines or measures power consumption and/or current draw for each of the vehicle systems having current demand for electrical energy storage device 118. For example, an galvanometer or similar current measuring device can be placed in the power circuit of some or all of the vehicle systems to directly determine or measure system current (or power) demand. For example, system current (or power) demand can be determined or measured indirectly by measuring the pulse width and/or frequency of a pulse width modulation (PWM) signal provided to one or more power converters.
At step 806, controller 304 evaluates each vehicle system to determine if the system is critical to user safety or compliance. In at least some embodiments, the controller 304 performs a status assessment that the criticality of a particular vehicle for safety or regulatory compliance may vary with location, jurisdiction, season, or even daily time. In at least some embodiments, the controller 304 performs this evaluation based at least in part on data or other information obtained by the read-only memory 322 and/or the random access memory 324. In other embodiments, the controller 304 performs this status assessment based at least in part on data or other information obtained from one or more external sources coupled by the communication. In addition, the source can be communicatively coupled to the controller 304 via one or more intermediate networks, the Internet, and/or a cellular communication network, the intermediate network including global positioning or similar geographic location services.
At step 808, controller 304 evaluates each vehicle system to determine if the system is critical to vehicle performance. In at least some embodiments, the controller 304 performs a state assessment that the criticality of a particular vehicle system for vehicle performance can vary with location, jurisdiction, season, or even daily time. In at least some embodiments, the controller 304 performs this evaluation based at least in part on data or other information obtained by the read-only memory 322 and/or the random access memory 324. In other embodiments, the controller 304 is based at least in part on data or other information obtained from external sources coupled by one or more communications. And this status assessment is performed. In addition, the source can be communicatively coupled to the controller 304 via one or more intermediate networks, the Internet, and/or a cellular communication network, the intermediate network including global positioning or similar geographic location services.
At step 810, controller 304 evaluates each vehicle system to determine if the system is critical to the vehicle range. In at least some embodiments, the controller 304 performs a state assessment that the criticality of a particular vehicle system for a vehicle range can vary with location, jurisdiction, season, or even daily time. In at least some embodiments, the controller 304 performs this evaluation based at least in part on data or other information obtained by the read-only memory 322 and/or the random access memory 324. In other embodiments, the controller 304 performs this status assessment based at least in part on data or other information obtained from one or more external sources coupled by the communication. In addition, the source can be communicatively coupled to the controller 304 via one or more intermediate networks, the Internet, and/or a cellular communication network, the intermediate network including global positioning or similar geographic location services.
At step 812, the controller 304 identifies any remaining vehicle systems that are not critical to safety criticality, performance criticality, or range critical as a "non-critical" vehicle system. Such systems typically include, for example, entertainment systems, headlight systems, and the like. The method 800 ends at step 814.
9 illustrates a thermal compensation method 900 and begins at step 902, in which the controller 304 adjusts one or more vehicle systems downwardly in response to the measured or determined temperature or a temperature increase rate that exceeds one or more thresholds. power consumption. In at least some embodiments, the controller 304 can arrange or configure the order of downward adjustment of power available to various vehicle systems based on the assessed criticality of the individual vehicle systems. In at least some embodiments, the controller 304 partially or completely eliminates the power available to adjust some or all of the vehicle systems critical to the user's safety critical or regulatory compliance. In other embodiments, the controller 304 reduces the power available to one or more vehicle systems based at least in part on the criticality of the evaluated vehicle system.
At step 904, controller 304 may adjust the energy available to one or more vehicle systems in response to the detected temperature or rate of temperature change outside of the defined threshold. In at least some embodiments, the controller 304 can adjust the available energy based on a prioritized definition of vehicle system criticality. For example, controller 304 may first perform energy availability adjustments for non-critical vehicle systems. Second, the controller 304 can make energy availability adjustments to performance critical vehicle systems. Third, the controller 304 can make energy availability adjustments for a range of critical vehicle systems. Finally, controller 304 may or may not perform power conditioning for a safety or regulatory compliance critical vehicle system. End at step 906.
For all vehicle systems, the energy availability reduction caused by controller 304 can be the same or different. For example, controller 304 may selectively reduce the available energy allocated to the entertainment system prior to reducing the available energy allocated to the headlight system. In another example, the controller may selectively reduce the available energy of the headlights (generally considered to be safety critical vehicle systems) during the daytime while reducing the available energy of the entertainment system. Thus, the order and extent of energy reduction or available to each vehicle system presents some operational and environmental factors.
Moreover, in at least some embodiments, the vehicle user can influence the vehicle system assessment performed by the controller 304. For example, in one embodiment, a mobile phone application or "app" can interface with at least a portion of the controller 304 interface. Via this interface, the controller 304 can enable the user to obtain vehicle system evaluation results. In at least some embodiments, the app causes the user to again obtain the degree of criticality that the controller 304 assigns to a particular vehicle system.
10 illustrates a thermal compensation method 1000 in which controller 304 adjusts the energy available to one or more vehicle systems in response to a measured or determined temperature or a rate of temperature increase below one or more thresholds. In at least some embodiments, the controller 304 can be arranged or configured for various vehicle systems based on the assessed criticality of the individual vehicle systems. The order in which the obtained power is adjusted upwards. In at least some embodiments, the controller 304 increases the energy available to one or more vehicle systems based at least in part on the criticality of the evaluated vehicle system and/or the needs of the vehicle user for the system. Method 1000 begins in step 1002.
At step 1004, controller 304 may adjust or increase the energy available to one or more vehicle systems in response to the detected temperature or rate of temperature change outside of the defined threshold. In at least some embodiments, the controller 304 can adjust the available energy based on a prioritized definition of vehicle system criticality. For example, first, controller 304 may increase energy availability for a safety critical vehicle system. Second, controller 304 can increase the energy availability of a range of critical vehicle systems. Third, controller 304 can increase the energy availability of a performance critical vehicle system. Finally, controller 304 can increase the energy availability of non-critical vehicle systems. The method 1000 ends at step 1006.
