Definitions

  • the disclosure relates generally to vehicles, and in particular to electric/hybrid vehicles that have a rechargeable battery that can operate/propel the vehicle.
  • Electric and/or hybrid vehicles often include some form of energy storage, such as a rechargeable battery, that provides the vehicle a source of energy for operating the vehicle. Because the temperature of the battery is often critical to safety and performance, electric and/or hybrid vehicles may have a heating/cooling system for the battery that may be enabled or disabled in order to heat or cool the battery to a target temperature. In addition, depending on the current temperature of the battery, electric or hybrid vehicles may adjust the limits for how much (and/or how quickly) energy may be withdrawn from or recouped to the battery during a vehicle maneuver or how much (and/or how quickly) energy may be discharged to or supplied from a charging station. However, it may not be optimal to base the activation of the heating/cooling and/or the limits to the energy consumption/recoup on the temperature of the battery alone.
  • FIG. 1 shows an example of a battery management system with context-aware battery temperature management that may generate instructions for heating/cooling the battery and/or for limiting the power consumption/recoup from/to the battery that may take into account the driving situation and/or operational configuration of the vehicle;

  • Autonomous vehicles may also include vehicles that control only some aspects of vehicle navigation, such as steering (e.g., to maintain a vehicle course between vehicle lane constraints) or some steering operations under certain circumstances, but may leave other aspects of vehicle navigation to the driver during other circumstances (e.g., braking under certain circumstances).
  • Autonomous vehicles may also include vehicles that share the control of one or more aspects of vehicle maneuver implementation/planning under certain circumstances (e.g., hands-on, such as responsive to a driver input) and vehicles that control one or more aspects of vehicle maneuvering under certain circumstances (e.g., hands-off, such as independent of driver input).

  • SAE level may have a value ranging from a minimum level, e.g. level 0 (illustratively, substantially no driving automation), to a maximum level, e.g. level 5 (illustratively, full driving automation).
  • Hybrid and electric vehicles may connect to charging stations in order to replenish their energy storage (e.g., one or more batteries), where energy may be withdrawn from the energy grid through the charging station to replenish the energy storage (e.g., recharge the battery).
  • charging stations may be bidirectional, meaning that energy could be offloaded (e.g., dispensed) to the energy grid from the energy storage of the electric vehicle.
  • Hybrid and electric vehicles may have the capability to generate their own power (e.g., through solar panels on the roof) or to recoup power from changes in motion (e.g., a braking system may recoup energy to the battery by transferring energy of motion into electrical energy that may be returned to the battery).
  • the temperature of the battery may be critical to its safe operation and to its overall performance.
  • electric vehicles often have a heating/cooling system that may be enabled depending on the temperature of the battery.
  • electric vehicles may adjust, depending on the temperature of the battery, the limits for how much (and/or how quickly) energy may be withdrawn from or recouped to the battery during a vehicle maneuver or how much (and/or how quickly) energy may be discharged to or supplied from a charging station. This means that if the battery temperature is very hot, the vehicle may limit the energy withdrawal to only a small trickle of energy. This may mean that the acceleration, velocity, or other high-energy consumption actions of the vehicle may be limited.
  • conventional systems that base the activation of the heating/cool system or base the energy limits simply on a battery temperature may not provide optimal, overall performance and safety of the battery and vehicle.
  • the temperature of the battery may need to be maintained at a target temperature to ensure that the battery is capable of supplying energy and to prevent battery degradation.

  • driving performance e.g., decrease in acceleration, velocity, driving range, etc.
  • battery performance may also degrade effective available output power and driving performance.
  • Battery temperature is not only influenced by external temperatures (e.g., ambient temperatures of the environment in which the vehicle may be operating), but also the amount of energy being withdrawn from the battery (e.g., by usage, by discharging to a charging station, etc.) or the amount of energy being supplied to the battery (e.g., while recouping energy from vehicle motion (e.g. through braking), by charging the battery from a charging station, etc.).
  • electric vehicles may use a Battery Temperature Management System (BTMS) to ensure that the temperature of the battery remains at a target temperature or within a target temperature range.
  • BTMS Battery Temperature Management System
  • a BTMS may include an active or passive cooling/heating system that may be enabled or disabled in order to set/maintain a target temperature or target temperature range. If the cooling/heating system is an active system (e.g., a liquid heat exchanger, a fan, a heater, etc.), activating the system may itself expend energy of the battery. In addition to or as an alternative to activating a cooling/heating system, a BTMS may also limit the amount of power extracted from or delivered to the battery. Limiting the amount of power consumed/recouped, may, in turn, limit the vehicle operation (e.g., limited acceleration, limited velocity, limited air-conditioning, etc.).
  • the vehicle operation e.g., limited acceleration, limited velocity, limited air-conditioning, etc.
  • the battery management system disclosed in more detail below may be able to improve the overall battery performance by taking into account the actual/predicted driving situation and/or vehicle operation.
  • the battery temperature management system may be enhanced to not only consider the current temperature of the battery but also to consider the specific driving situation, the specific operational configuration, and/or other factors that may be used to optimize the management of the battery temperature.
  • the disclosed battery management system might set a limit to the maximum power consumptions during accelerations, which may reduce the battery temperature and save energy.
  • the disclosed battery management system might prioritize safety over energy savings and provide higher limits (e.g., no limit) to the vehicle’s power consumption for accelerations, braking, etc. while also expending more energy on the battery’s active cooling system.
  • the disclosed battery management system might provide context- aware braking.
  • an electric vehicle may be equipped with an energy-recovery braking system, where the motors that drive the wheels may also spin in the opposite direction to decelerate the vehicle while harvesting energy from the deceleration (also called energy recoup, recouping, recoupment, or recuperation).
  • energy recoup, recouping, recoupment, or recuperation also called energy recoup, recouping, recoupment, or recuperation.
  • the disclosed battery management system may detect an emergency braking situation that, to prioritize driving safety, the vehicle may need to use all possible deceleration capabilities of the vehicle, so the disclosed battery management system may enable energy recoup from the braking system, even at this particular temperature range.
  • the disclosed battery management system may consider more than battery temperature when determining whether to enable/disable the heating/cooling system and/or whether to limit vehicle operation.
  • the disclosed battery management system may provide instructions to the vehicle systems (e.g., the heating/cooling system and/or the driving system) that provides optimal battery temperature management for the given situation.
  • the disclosed battery management system may take into account static environment information such as road slope, distance to junctions, the destination, etc., to precondition the battery temperature for energy harvesting on descents and smarter deceleration (e.g., adaptive energy recuperation) when approaching intersections.
  • the disclosed battery management system may also take into account dynamic environment information such as weather forecasts, the current traffic situation, the predicted traffic situation, etc. so that, for example, the disclosed battery management system may optimize battery temperature control settings to prioritize improved deceleration in emergency situations or improved energy recuperation when considering the right-of-way at intersections.

Description

ENERGY SUPPLY- AND DEMAND-BASED CONFIGURATION AND OPERATION OF ELECTRIC VEHICLES
Technical Field
[0001] The disclosure relates generally to vehicles, and in particular to electric/hybrid vehicles that have a rechargeable battery that can operate/propel the vehicle.
Background
[0002] In recent years, consumers and manufacturers have been moving from combustion engine vehicles to electric vehicles or hybrid vehicles. Electric and/or hybrid vehicles often include some form of energy storage, such as a rechargeable battery, that provides the vehicle a source of energy for operating the vehicle. Because the temperature of the battery is often critical to safety and performance, electric and/or hybrid vehicles may have a heating/cooling system for the battery that may be enabled or disabled in order to heat or cool the battery to a target temperature. In addition, depending on the current temperature of the battery, electric or hybrid vehicles may adjust the limits for how much (and/or how quickly) energy may be withdrawn from or recouped to the battery during a vehicle maneuver or how much (and/or how quickly) energy may be discharged to or supplied from a charging station. However, it may not be optimal to base the activation of the heating/cooling and/or the limits to the energy consumption/recoup on the temperature of the battery alone.

[0012] As used herein, “memory” is understood as a computer-readable medium (e.g., a non- transitory computer-readable medium) in which data or information can be stored for retrieval. References to “memory” included herein may thus be understood as referring to volatile or nonvolatile memory, including random access memory (RAM), read-only memory (ROM), flash memory, solid-state storage, magnetic tape, hard disk drive, optical drive, 3D XPoint™, among others, or any combination thereof. Registers, shift registers, processor registers, data buffers, among others, are also embraced herein by the term memory. The term “software” refers to any type of executable instruction, including firmware.
[0013] Unless explicitly specified, the term “transmit” encompasses both direct (point-to- point) and indirect transmission (via one or more intermediary points). Similarly, the term “receive” encompasses both direct and indirect reception. Furthermore, the terms “transmit,” “receive,” “communicate,” and other similar terms encompass both physical transmission (e.g., the transmission of radio signals) and logical transmission (e.g., the transmission of digital data over a logical software-level connection). For example, a processor or controller may transmit or receive data over a software-level connection with another processor or controller in the form of radio signals, where the physical transmission and reception is handled by radio-layer components such as radio frequency (RF) transceivers and antennas, and the logical transmission and reception over the software-level connection is performed by the processors or controllers. The term “communicate” encompasses one or both of transmitting and receiving, i.e., unidirectional or bidirectional communication in one or both of the incoming and outgoing directions. The term “calculate” encompasses both “direct” calculations via a mathematical express! on/formula/relationship and ‘indirect’ calculations via lookup or hash tables and other array indexing or searching operations.
[0014] A “vehicle” may be understood to include any type of driven object. By way of example, a vehicle may be a driven object with a combustion engine, a reaction engine, an electrically driven object, a hybrid driven object, or a combination thereof. A vehicle may be or may include an automobile, a bus, a mini bus, a van, a truck, a mobile home, a vehicle trailer, a motorcycle, a bicycle, a tricycle, a train locomotive, a train wagon, a moving robot, a personal transporter, a boat, a ship, a submersible, a submarine, a drone, an aircraft, or a rocket, among others. As used herein, references to an “electric vehicle,” “EV,” and “hybrid vehicle” include any type of vehicle with an energy storage (e.g., a battery) that is capable of operating (e.g. propelling) the vehicle, irrespective of other sources of energy, if any, from which the vehicle may be alternatively or additionally operated (e.g., sources such as a combustion engine, solar panels, etc.).
[0015] The term “autonomous vehicle” may describe a vehicle capable of implementing at least one vehicle maneuver without driver input. A vehicle maneuver may describe or include a change in one or more of steering, braking, acceleration/deceleration, etc. of the vehicle. A vehicle may be described as autonomous even where the vehicle is not fully automatic (for example, is fully operational with driver input or without driver input). Autonomous vehicles may include those vehicles that can operate under driver control during certain time periods and without driver control during other time periods. Autonomous vehicles may also include vehicles that control only some aspects of vehicle navigation, such as steering (e.g., to maintain a vehicle course between vehicle lane constraints) or some steering operations under certain circumstances, but may leave other aspects of vehicle navigation to the driver during other circumstances (e.g., braking under certain circumstances). Autonomous vehicles may also include vehicles that share the control of one or more aspects of vehicle maneuver implementation/planning under certain circumstances (e.g., hands-on, such as responsive to a driver input) and vehicles that control one or more aspects of vehicle maneuvering under certain circumstances (e.g., hands-off, such as independent of driver input). Autonomous vehicles may also include vehicles that control one or more aspects of vehicle navigation under certain circumstances, such as under certain environmental conditions (e.g., spatial areas, roadway conditions). In some aspects, autonomous vehicles may handle some or all aspects of braking, speed control, velocity control, and/or steering of the vehicle.
[0016] An autonomous vehicle may include those vehicles that can operate without a driver. The level of autonomy of a vehicle may be described or determined by the Society of Automotive Engineers (SAE) level of the vehicle (e.g., as defined by the SAE, for example in SAE J30162018: Taxonomy and definitions for terms related to driving automation systems for on road motor vehicles) or by other relevant professional organizations. The SAE level may have a value ranging from a minimum level, e.g. level 0 (illustratively, substantially no driving automation), to a maximum level, e.g. level 5 (illustratively, full driving automation).
[0017] Hybrid and electric vehicles may connect to charging stations in order to replenish their energy storage (e.g., one or more batteries), where energy may be withdrawn from the energy grid through the charging station to replenish the energy storage (e.g., recharge the battery). In addition, charging stations may be bidirectional, meaning that energy could be offloaded (e.g., dispensed) to the energy grid from the energy storage of the electric vehicle. Hybrid and electric vehicles may have the capability to generate their own power (e.g., through solar panels on the roof) or to recoup power from changes in motion (e.g., a braking system may recoup energy to the battery by transferring energy of motion into electrical energy that may be returned to the battery).
[0018] As noted above, the temperature of the battery may be critical to its safe operation and to its overall performance. As such, electric vehicles often have a heating/cooling system that may be enabled depending on the temperature of the battery. In addition, electric vehicles may adjust, depending on the temperature of the battery, the limits for how much (and/or how quickly) energy may be withdrawn from or recouped to the battery during a vehicle maneuver or how much (and/or how quickly) energy may be discharged to or supplied from a charging station. This means that if the battery temperature is very hot, the vehicle may limit the energy withdrawal to only a small trickle of energy. This may mean that the acceleration, velocity, or other high-energy consumption actions of the vehicle may be limited. However, conventional systems that base the activation of the heating/cool system or base the energy limits simply on a battery temperature may not provide optimal, overall performance and safety of the battery and vehicle.
[0019] Generally, the temperature of the battery may need to be maintained at a target temperature to ensure that the battery is capable of supplying energy and to prevent battery degradation. For example, if the temperature of a typical rechargeable vehicle battery drops below freezing (e.g., below 0 °C or 32 °F), electrochemical reactions slow with a corresponding decrease in effective available output power and thus driving performance (e.g., decrease in acceleration, velocity, driving range, etc.). In addition, at below-freezing temperatures, there is an increased risk of battery damage during a charging operation. At temperatures above 30 °C (86 °F), for example, battery performance may also degrade effective available output power and driving performance. These high temperatures are additionally problematic because there may already be high power demands on the battery because, for example, at high temperatures, there may be a need to operate the in-cabin air conditioner. If the battery temperature reaches about 40 °C (104 °F), irreversible damage to the battery may occur. At between 70 and 100 °C, thermal runaway may occur, causing a chain reaction that may destroy one or more cells and may spread to adjacent cells, eventually destroying the entire battery.
[0020] Battery temperature is not only influenced by external temperatures (e.g., ambient temperatures of the environment in which the vehicle may be operating), but also the amount of energy being withdrawn from the battery (e.g., by usage, by discharging to a charging station, etc.) or the amount of energy being supplied to the battery (e.g., while recouping energy from vehicle motion (e.g. through braking), by charging the battery from a charging station, etc.). As such, electric vehicles may use a Battery Temperature Management System (BTMS) to ensure that the temperature of the battery remains at a target temperature or within a target temperature range. A BTMS may include an active or passive cooling/heating system that may be enabled or disabled in order to set/maintain a target temperature or target temperature range. If the cooling/heating system is an active system (e.g., a liquid heat exchanger, a fan, a heater, etc.), activating the system may itself expend energy of the battery. In addition to or as an alternative to activating a cooling/heating system, a BTMS may also limit the amount of power extracted from or delivered to the battery. Limiting the amount of power consumed/recouped, may, in turn, limit the vehicle operation (e.g., limited acceleration, limited velocity, limited air-conditioning, etc.). In a conventional BTMS, activation of the heating/cool system or placing limits of the vehicle operation is based solely on battery temperature and may not be optimum for the overall situation. [0021] In contrast to conventional systems, the battery management system disclosed in more detail below may be able to improve the overall battery performance by taking into account the actual/predicted driving situation and/or vehicle operation. In particular, the battery temperature management system may be enhanced to not only consider the current temperature of the battery but also to consider the specific driving situation, the specific operational configuration, and/or other factors that may be used to optimize the management of the battery temperature. For example, if an electric vehicle is driving on an empty highway and needs to reduce battery temperature, the disclosed battery management system might set a limit to the maximum power consumptions during accelerations, which may reduce the battery temperature and save energy. On the other hand, if an electric vehicle is driving in dense traffic and may be frequently overtaking other vehicles, braking, and reaccelerating, the disclosed battery management system might prioritize safety over energy savings and provide higher limits (e.g., no limit) to the vehicle’s power consumption for accelerations, braking, etc. while also expending more energy on the battery’s active cooling system.
[0022] As another example, the disclosed battery management system might provide context- aware braking. As noted earlier, an electric vehicle may be equipped with an energy-recovery braking system, where the motors that drive the wheels may also spin in the opposite direction to decelerate the vehicle while harvesting energy from the deceleration (also called energy recoup, recouping, recoupment, or recuperation). If the vehicle’s battery is operating within a particular temperature range where energy recoup from the braking system would normally be disabled, the disclosed battery management system may detect an emergency braking situation that, to prioritize driving safety, the vehicle may need to use all possible deceleration capabilities of the vehicle, so the disclosed battery management system may enable energy recoup from the braking system, even at this particular temperature range.
[0023] In sum, the disclosed battery management system may consider more than battery temperature when determining whether to enable/disable the heating/cooling system and/or whether to limit vehicle operation. By considering the particular driving situation, the preferences of the driver, the safety needs of the vehicle, etc., the disclosed battery management system may provide instructions to the vehicle systems (e.g., the heating/cooling system and/or the driving system) that provides optimal battery temperature management for the given situation. For example, the disclosed battery management system may take into account static environment information such as road slope, distance to junctions, the destination, etc., to precondition the battery temperature for energy harvesting on descents and smarter deceleration (e.g., adaptive energy recuperation) when approaching intersections. The disclosed battery management system may also take into account dynamic environment information such as weather forecasts, the current traffic situation, the predicted traffic situation, etc. so that, for example, the disclosed battery management system may optimize battery temperature control settings to prioritize improved deceleration in emergency situations or improved energy recuperation when considering the right-of-way at intersections.
[0024] FIG. 1 shows a battery management system 100 with a context-aware battery temperature management system 110 that may generate instructions for heating/ cooling the battery and/or for limiting the power consumption/recoup from/to the battery that may take into account not only temperature but also the driving situation and/or operational configuration of the vehicle. The context-aware battery temperature management system 110 may receive information about the ambient temperature 104 (e.g., from an air temperature sensor that senses the environment in which the vehicle is operating), the battery temperature 108 (e.g., from a temperature sensor of the battery), or any other parameters related to the state of the battery (e.g., the amount of current being drawn/injected from/to the battery, the power density, the voltage, etc.). As should be understood, the temperatures or other battery state parameters may be the current values or forecasted values for later point(s) in time. The context-aware battery temperature management system 110 may also receive information about the driving situation 114 of the vehicle. This may include, for example, information about the road geometries along a planned route (e.g., distances, changes in elevation (inclines/declines), curvature, traction), traffic along the planned route (e.g., current/ expected traffic density, timings of traffic lights, average speeds along roads, etc.), weather along the planned route, the status of a safety system (e.g., a driver assistance system, an automated driving system, an advanced driver assistance system) that may maintain the current and predicted safety of the vehicle (e.g., its static and dynamic relationship to other objects within the environment), etc. As should be appreciated, the driving situation, traffic situation, weather information, etc. may be received from internal or external sensors, or received via messages received by the battery management system 100 (e.g., wirelessly via a receiver/transceiver). For example, the battery management system 100 may receive such information from an extemal/cloud-based server.
[0025] The context-aware battery temperature management system 110 may also receive information about the vehicle configuration 118, which may include, for example driver preferences for vehicle operation (e.g., a preferred driving mode (e.g., a “sport” mode that prioritizes acceleration over energy consumption efficiency, a “green” mode that prioritizes energy saving over speed/acceleration)), operational limits of the vehicle (e.g., safety-related limits from a safety system (e.g., limits to acceleration/deceleration for current road conditions, limits to velocity when rounding a curve, limits to braking force in icy conditions, etc.).
[0026] Based on the received information, the context-aware battery temperature management system 110 may determine an optimized temperature action plan that contains the operational parameters for controlling, at battery heating/cooling control 120, the temperature of the battery (e.g., operational parameters for when, how, and what extent to activate the battery cooling/heating system (e.g., a heater, an air conditioner, a liquid heat exchanger, etc.)). The temperature action plan may also include power control 130 that may adjust/place limits on the amount of energy that may be withdrawn from or supplied to the battery at a given time, where the power control 130 may be associated with vehicle instructions that may adapt the driving configuration of the vehicle so as to satisfy the limits. In this manner, the context-aware battery temperature management system 110 may optimize the received inputs into a dynamic plan that is not simply a static controller based solely on the temperature of the battery.
[0027] The schematic flow diagram 200 of FIG. 2 shows exemplary inputs and outputs for analyzing driving situations, which may be used and/or determined by the battery management system (e.g., battery management system 100). For example, the battery management system may use information about the driving situation of the vehicle (e.g., at driving situation 114) to estimate driving distances, heights, velocities, etc. and expected energy consumption corresponding thereto. As one example, the battery management system may receive information about the planned path of the vehicle, such as the height/elevations along the driving path 201, traffic information 203, driving distances, speed limits, etc., and use this information to perform battery-related road/path analysis 250. Based on this information, the battery management system may predict an expected velocity for the vehicle along each segment in the planned path, where each segment is defined by a series of waypoints along the planned path to a destination. Then, from the change in height along each segment, combined with the expected velocity for the segment, the battery management system may predict an estimated requirement 253 (e.g., the energy consumption/recoupment required from/to the battery to travel the planned path). As should be appreciated, any information about the driving situation may be used by the battery management system to estimate the expected requirements for the vehicle’s energy consumption/recoupment along the planned path.
[0028] In addition to road/path analysis 250, the battery management system may perform a battery-related situational analysis 260 to estimate relevant operational limits/requirements 265 associated with the current/predicted situation 205. As one example, the situational analysis may be safety-related, where the vehicle’s relationship to other objects in the environment may be analyzed for safety. For example, the current or predicted road conditions, road curvature, nearby pedestrians, and/or vehicle density, as examples, may suggest limits or requirements for acceleration, braking, velocity, etc., each of which, when limited or when a minimum level is required, may impact the battery energy consumption. Using acceleration as an example, the situational analysis 260 may determine how demanding the current driving situation is and how aggressive the vehicle should accelerate/decelerate to be able to safely maneuver in the current situation. This acceleration/deceleration may be understood as an acceleration aggressiveness requirement or score that may be used by the battery management system to plan the controls for operating the heating/cooling and for the energy consumption/recoup of the battery. As should be appreciated, any information about the driving situation may be used by the battery management system to estimate the expected operational limits/requirements 265. [0029] One example of how an analysis of the driving situation may impact the battery management system is where a vehicle approaches an intersection (e.g. a round-about) with good visibility. If there is a large amount of traffic at the intersection, there is a high likelihood that the vehicle will need to slow down and yield the right-of-way to other vehicles before entering the intersection. In such a situation, the battery management system may prioritize energy recuperation settings by setting the recuperation requirement to maximum and setting the maximum allowed acceleration to a minimum. In the opposite situation, where there is a low amount of traffic at the intersection, the battery management system may prioritize acceleration by setting the recuperation requirement to a minimum (e.g., only a small amount of deceleration may be needed to slow the vehicle just enough to safely traverse through the intersection), but acceleration operations may be unlimited. This type of operation of the disclosed battery management system is in contrast to conventional systems, where the recuperation and available acceleration would be independent of the situation and set to static values based on the battery temperature. Thus, in a conventional system, the vehicle may decelerate too quickly (e.g., too much recuperation) or too slowly (e.g., too little recuperation). This may be improved by the disclosed battery management system, which may dynamically adapt the operational limits to the driving situation.
[0030] Another example is an alpine road that has long ascents/descents. By analyzing the route and the road profile (e.g., elevation changes along segments of the road along the path) within the battery management system, the battery temperature management system may begin configuring settings to preconditioning the battery so as to maximize energy recuperation in the corresponding road segments of descent (or minimize energy loss in the corresponding road segments of ascent). This may mean that the battery management system may limit the possible acceleration on the last portion of an ascending road segment so that the battery will be properly conditioned for recoupment on the decent. Or, the battery management system may activate the cooling system to cool the temperature of the battery so that it is at an optimum value when the vehicle starts the descent.
[0031] Another example is an emergency situation. The battery management system may detect as part of the driving situation analysis that an emergency situation requires configuration settings that prioritize safety over battery health (e.g., an emergency override). Such an emergency situation may occur, for example, where a vehicle is overtaking another vehicle and an unexpected object appears in the vehicle’s overtaking path. In such a situation, the battery management system may configure the acceleration so as to allow for faster acceleration (e.g., to allow the vehicle to quickly overtake the other vehicle to avoid a collision) than would be normally allowed for the current battery temperature and/or configure the breaking to allow for more forceful, higher-recoup braking (e.g., to allow the vehicle to quickly brake and end the overtake to avoid a collision) than would be normally allowed for the current battery temperature. A battery management system with such a feature would enhance the safety of the vehicle beyond conventional battery management systems, where there would be a fixed limit to the acceleration/braking based solely on the temperature of the battery.
[0032] FIG. 3 shows a battery management system 300 with a context-aware battery temperature management system 310 that may generate instructions for heating/ cooling the battery and/or for limiting the power consumption/recoup from/to the battery that may take into account not only temperature but also the driving situation and/or operational configuration of the vehicle. The battery management system 300 may be similar to battery management system 100 (e.g., context-aware battery temperature management system 310 may correspond to context-aware battery temperature management system 110, ambient temperature 304 may correspond to ambient temperature 104, battery temperature 308 may correspond to battery temperature 108, driving situation 314 may correspond to driving situation 114, driver preference/vehicle operation configuration 318 may correspond to vehicle configuration 118), and the description of battery management system 100 and schematic flow diagram 200 may also apply to battery management system 300. For simplicity, corresponding features described above may not be repeated below. As should be appreciated, while battery management system 300 may show features in additional detail as compared to battery management system 100, this is not intended to limit battery management system 100.
[0033] The context-aware battery temperature management system 310 may include a parameter optimizer 380 that may, based on the estimated energy requirements, operational limits/requirements, driver-based requirements/limits from the analysis of the driving situation 314 and/or the driver preference/vehicle operational configuration 318, optimize a temperature action plan for the vehicle. The temperature action plan may include instructions for controlling, at 320, the battery’s heading/cooling system and/or instructions for power control 330 that may adjust/place limits on the amount of energy that may be withdrawn from or supplied to the battery at a given time, where the power control 330 may be associated with vehicle instructions that may adapt the driving configuration of the vehicle so as to satisfy the limits. Thus, the optimization may be designed to optimize a cooling/heating power parameter for controlling, at 320, the heating/cooling system and a power restriction parameter for the power control 330.
[0034] The parameter optimizer 380 may utilize a vehicle model 381 to predict the required power for the given set of inputs for the driving situation 314 and/or driver preference/vehicle operational configuration 318. For example, the parameter optimizer 380 may receive estimated energy requirements for a given driving path (e.g., changes in height along with a velocity for road segments along the driving path) and operational limits/restrictions (e.g., an acceleration aggressiveness). Once suitable parameter setting(s) are determined, the parameter optimizer 380 may send the parameter setting(s) to the battery model 390 that generates instructions for battery conditioning (e.g., using the battery heating/cooling control 320 to heat, cool and/or using power control 330 to limit energy withdrawn from or recuperated to the battery, etc.). One example of the determined parameter settings is shown in table 385, where the determined cooling power (e.g., a cooling/heating power parameter) and the determined driving power (e.g., a power restriction parameter) are shown for the different road segments (delta 1, delta2, delta3).
[0035] The battery model 390 may include a state prediction modeler that makes predictions for the estimated battery conditioning (e.g., estimated target temperatures for the battery 395) at future points in time. Such battery conditioning predictions may be helpful for avoiding continuously changing parameters (e.g., where the instructions for battery conditioning change from one time step to the next and may not be effective over a longer time horizon). Thus, the battery conditioning predictions may be provided back to the parameter optimizer 380 so that the parameter optimizer 380 may take them into account during optimization, so that it may consider the impact of its determined parameter setting(s) on future battery conditions. For example, after the estimated the parameter optimizer 380 receives the predictions for the estimated battery conditioning (e.g., estimated temperatures), it may check to see whether quality requirements/goals (e.g., predefined criterion associated with a parameter) have been reached and/or whether the determined parameter(s) were the optimal parameters, including, for example, whether the predictions for estimated temperatures fulfills the requirements of the expected temperature rage, whether the acceleration profile (e.g., acceleration limits) meets the driver’s preferences for acceleration, whether the cooling power has been minimized, etc.
[0036] The context-aware battery temperature management system 310 may also include a memory 388 (e.g., a database) for storing past parameter setting(s) along with the given set of inputs that led to the determined parameter setting(s). The parameter optimizer 380 may utilize past parameter setting(s) from memory 388 to accelerate finding parameter setting(s) for the current set of inputs. The memory 388 may be understood as a long- short-term memory (LSTM), where short term decisions avoid that the parameter optimizer 380 toggles between multiple states of parameter setting(s) and long term decisions are used to accelerate finding new solutions for the current set of inputs. As should be appreciated, the memory 388 may also include data from other vehicles (e.g., received from an external server/cloud-based platform). For example, the memory 288 may communicate with an external server (e.g., wirelessly via a receiver/transceiver) to receive a database of context-specific power management decisions and the inputs they were based on. In this manner, the parameter optimizer 380 may utilize the experience of other vehicles in its optimization algorithm. In addition, the battery management system may transmit (e.g., wirelessly via a transmitter/transceiver), information it collects in memory 388 to the external database of context-specific power management decisions and corresponding inputs. By sharing such data, the context awareness of the parameter optimizer 380 may be improved over time.
[0037] As should be appreciated, the parameter optimizer 380 may use any type of algorithm to determine the parameter setting(s) based on the inputs. For example, the optimizer may prioritize competing goals with a weighting system, select parameter setting(s) based on a mixed- integer program solver (linear or non-linear), an iterative solver such as simulated annealing, a leam-based model that utilizes a trained set of parameter setting(s) and inputs, etc.
[0038] As should be understood, the battery management systems discussed above are not necessarily limited to situations where the vehicle is actively in use (e.g., traveling toward a destination). The battery management systems discussed above may also apply to idle times where the vehicle is connected to a charging station. For example, the battery management system may set power control limits the transfer of power between the vehicle’ s battery and the charging station while charging/discharging the battery based on the received information. For example, if the weather at the charging station is expected to change while the vehicle is connected, the battery management system may wait to begin transferring power from/to the charging station until after the weather even occurs, when the battery may be in a better condition to charge/discharge.
