Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, apparatus, vehicle, and storage medium for distributing electrical energy from a vehicle battery. Background Technology

[0002] With the further development of the new energy vehicle market, the penetration rate of various new energy vehicles is increasing. Advances in power battery technology, automotive energy-saving and consumption-reducing technology, fast charging technology, and clean energy technology have provided more possibilities for energy-saving optimization of new energy vehicle models. Intelligent vehicles possess increasingly more new functions, and their electrical architecture is more complex than that of traditional vehicles, with more controllers and electrical components. New energy vehicles typically have more than two energy storage devices, most notably high-voltage batteries and low-voltage batteries. High-voltage batteries are mainly used to drive the vehicle and supply power to electrical loads after the vehicle starts, while also replenishing the low-voltage batteries. Low-voltage batteries are mainly used to supply power to all vehicle controllers and low-voltage loads when the vehicle is not running, preparing the vehicle for startup.

[0003] In response to the increasing situation where vehicles rely solely on low-voltage batteries to power the load when parked for extended periods or when unused, leading to battery depletion, a smart DC-DC (Direct Current) charging solution can be adopted to reduce the likelihood of vehicle battery depletion. This technology involves periodically waking up the vehicle after it has been locked for a certain period and charging the battery via DC-DC output from the high-voltage battery, based on the battery's different voltage values. The charging time varies depending on the battery's voltage gradient.

[0004] However, the relevant technology cannot detect the battery's charge level in real time, nor can it accurately estimate the battery's charge level during charging, making it impossible to determine whether the battery is fully charged. Furthermore, periodically waking up the vehicle to measure the battery voltage will also consume the battery's charge, increasing the possibility of the battery running out of power.

Conversely, if sunlight is abundant, the battery is used to charge the DC-DC high-voltage battery. Furthermore, the system protects the battery's safe charge level based on weather conditions. This addresses the problem of related technologies being unable to accurately estimate battery charge and the increased likelihood of battery depletion due to periodic vehicle wake-ups, ensuring the most efficient use of battery energy and preventing battery depletion.

[0037] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0038] The following description, with reference to the accompanying drawings, describes a vehicle battery power distribution method, apparatus, vehicle, and storage medium according to embodiments of this application. Addressing the issues mentioned in the background art, such as the inability to accurately estimate battery capacity and the increased likelihood of battery depletion due to periodic vehicle wake-ups, this application provides a vehicle battery power distribution method. This method utilizes a controller to estimate the power of low-voltage loads or detect actual power, avoiding the need for periodic vehicle wake-ups to measure battery power consumption and optimizing battery depletion management during extended parking periods. Simultaneously, it coordinates solar energy and high-voltage battery power, prioritizing solar charging when sunlight conditions are good. Towards the end of the trip, DC-DC power supply is reduced, utilizing solar energy to power the vehicle load and battery. If the battery has sufficient charge, it can also replenish the high-voltage battery. When parked, if sunlight conditions are good, the battery is charged via the DC-DC high-voltage battery. Furthermore, the method protects the battery's safe charge level based on weather conditions, optimizing power distribution and addressing battery depletion issues to a certain extent, improving battery efficiency, and extending battery life.

[0039] Specifically, Figure 1 This is a schematic flowchart illustrating a power distribution method for a vehicle battery provided in an embodiment of this application.

[0040] like Figure 1 As shown, the energy distribution method of the vehicle battery includes the following steps:

[0041] In step S101, the current working status of the vehicle is obtained.

[0042] The vehicle's operating status can be driving, stopped, powered off, or powered on.

[0043] For example, if the current vehicle is in a driving state, then the obtained current vehicle operating state is the driving state; if the current vehicle is in a power-off state, then the obtained current vehicle operating state is the power-off state. To avoid redundancy, this will not be elaborated on in detail here.

[0044] In step S102, when the working state is the power-off state, at least one load that needs to be kept in the power-on state in the power-off state is obtained, and the first available power of the current vehicle battery is determined. Based on at least one load and the first available power of the battery, it is determined whether the current battery meets the preset charging conditions.

[0045] Optionally, in some embodiments, determining whether the current battery meets the preset charging conditions based on at least one load and the first available charge of the battery includes: calculating the current consumption and power consumption of the current vehicle after power-off based on at least one load; calculating the maximum available time of the battery based on the current consumption, power consumption and the first available charge of the battery; obtaining the current power-off time of the current vehicle, and determining that the current battery meets the preset charging conditions when the current power-off time reaches the maximum available time.

[0046] Specifically, the electrical load during sleep mode is estimated, and the available time for low-voltage power consumption to reach the battery's safety threshold is calculated. A timer is then set to wake the vehicle system and charge the battery. Specifically, the controller should have the capability to monitor the current of all power ports when powered on. After the vehicle is locked, the controller enters the post-operation phase. Based on the total current of all loads that still need to operate during sleep mode, and the estimated available battery power based on the battery voltage, the maximum available battery power during sleep mode is calculated. Then, considering an increased safety threshold, a timer is set, and the timer control unit is responsible for waking the vehicle network and issuing a power request. During timer operation, if remote control or other conditions activate vehicle wake-up, the timer is recalculated and corrected.

[0047] In actual implementation, such as Figure 2 As shown, Figure 2 This is a flowchart illustrating the pre-power-down load estimation and post-power-down timing wake-up of the vehicle, according to an embodiment of this application.

[0048] S201 When the system receives a power-down request, it first determines whether the battery power is less than the minimum safe power. If it is less, it directly sends a power-up request. If it is not less, it determines the list of loads that need to continue working after power-down.

[0049] S202, calculate the power after power-off based on the load list.

[0050] S203 then estimates the wake-up time after power-off based on the current battery charge and the load power after power-off.

[0051] S204, set timer, power-off sleep mode.

[0052] S205: If the timer expires, the vehicle will be woken up to start charging. During the process, other functions that wake up the vehicle will also determine whether the battery level has reached the required level for charging and will then perform the charging operation.

[0053] S206, power off after completing the charging process.

[0054] Optionally, in some embodiments, determining whether the current battery meets the preset charging conditions based on at least one load and the first available charge of the battery further includes: detecting the real-time current and real-time load power of all electrical loads in the current vehicle power-off state; calculating the real-time available charge of the battery based on the first available charge of the battery and the real-time current and real-time load power of all electrical loads; and determining that the current battery meets the preset charging conditions if the real-time available charge is less than a preset available charge threshold.

[0055] Specifically, for controllers with port current detection functionality after power-off, the controller monitors the load current of the controlled ports in real time after power-off to calculate the vehicle's power consumption and estimate the time it takes for the battery to reach a safe charge threshold, thus determining whether to wake the vehicle to charge the battery. Specifically, the controller should have the capability to monitor the current of all power ports during power-off sleep mode. After the vehicle is locked, the controller enters a post-operation phase, estimating the available charge based on the battery voltage. After sleep mode, it calculates the remaining available battery charge in real time based on the sum of all collected load currents. If the charge falls below the threshold, the vehicle is woken up and a charging request is sent to the network. If the vehicle is woken up by remote control or other conditions while in sleep mode, all conditions for this function are recalculated.

[0056] In actual implementation, such as Figure 3 As shown, Figure 3 This is a flowchart for determining whether to wake up the vehicle by monitoring the current in real time based on the load after power-off.

[0057] S301: When the system receives a power-down request, it will send a power-up request directly if the battery power is less than the minimum safe power level, based on the real-time estimated battery power.

[0058] S302: If the battery charge is not less than the minimum safe charge, it will enter power-off hibernation mode.

[0059] S303, the central controller calculates the load power in real time based on the current of each electrical load obtained in the power-off state, thereby obtaining the change in battery power.

[0060] S304: If the battery level is lower than the minimum safe level, the vehicle will be woken up and the battery level will be re-estimated. After confirmation, a power-up request will be sent. Other functions that wake up the vehicle follow the same power-down judgment process as above.

[0061] S305, target value for power replenishment.

[0062] S306, power off after performing a power-up.

[0063] In step S103, if the current battery meets the preset charging conditions, the light intensity at the current location of the vehicle and the available output power of the high-voltage battery pack are obtained, and the battery is charged according to the light intensity and / or the available output power of the high-voltage battery pack.

[0064] Optionally, in some embodiments, replenishing the battery based on the light intensity and / or the available output power of the high-voltage battery pack includes: calculating a first available output power and a first future available duration of solar energy based on the light intensity; if the first available output power is greater than a first preset output power and the first future available duration is greater than the first preset duration, then powering the battery with solar energy; otherwise, determining whether the available output power of the high-voltage battery pack is greater than a second preset output power and whether the available charge of the high-voltage battery pack is greater than a first preset charge; if the available output power of the high-voltage battery pack is greater than the second preset output power and the available charge of the high-voltage battery pack is greater than the first preset charge, then replenishing the battery with the high-voltage battery pack; otherwise, pushing a charging reminder to a preset mobile terminal to remind the user to charge.

[0065] Specifically, based on future sunlight conditions, the available duration of solar energy is determined in real time, and the minimum safe battery capacity threshold is determined comprehensively based on this available duration. In particular, when the vehicle is awake, the available sunlight duration conditions for future weather are received in real time, and the available sunlight duration is calculated. The minimum safe battery capacity threshold is determined based on the available sunlight duration; the longer the available duration, the lower the safe battery capacity threshold, and vice versa.

[0066] In actual implementation, such as Figure 4 As shown, Figure 4 This is a flowchart for calculating the minimum safe capacity of a battery based on certain conditions.

[0067] S401 sets a timer to update periodically, updating the minimum safe battery charge only between sunrise and sunset.

[0068] S402, based on the lighting conditions obtained from environmental perception and the current minimum safe battery charge value obtained.

[0069] S403, obtain future weather conditions.

[0070] S404 calculates the percentage of available light over a future period.

[0071] S405, look up the table to obtain the minimum safe power correction value.

[0072] S406, revised minimum safe power limit.

[0073] S407 provides minimum limit protection for the minimum safe power limit.

[0074] S408, if sunset time is reached, the limit update will stop.

[0075] Optionally, in some embodiments, after obtaining the current vehicle's operating state, the method further includes: when the operating state is driving, obtaining the current vehicle's current location, target location, a second available duration of solar energy determined by the current location and target location, a third available duration of solar energy after reaching the target location, the vehicle's average load power, and the second available battery power; if the second available battery power is greater than a second preset battery power, the second available duration is greater than a second preset duration, the third available duration is greater than a third preset duration, and the difference between the first available average power of solar energy and the vehicle's average load power within a first preset time period is greater than a first preset threshold, then the solar energy is used to power the current vehicle. The vehicle's load is powered and / or the battery is recharged; otherwise, the battery is recharged simultaneously via solar energy and a high-voltage battery pack. When the vehicle's load is powered and / or the battery is recharged via solar energy, if the second available power is greater than the third preset power, the third available duration is greater than the fourth preset duration, the third available duration is greater than the fifth preset duration, and the difference between the first available average power of solar energy and the average power of the vehicle's load within the second preset time period is greater than the second preset threshold, then the high-voltage battery pack is recharged via solar energy and the battery, wherein the fourth preset duration is greater than the second preset duration, the fifth preset duration is greater than the third preset duration, and the second preset threshold is greater than the first preset threshold.

[0076] Specifically, when the vehicle's destination is known and sunlight conditions are sufficient, the DC-DC converter stops working, prioritizing solar power for low-voltage loads. Any remaining solar power is used to charge the battery. During vehicle operation, real-time navigation information is acquired. Once the distance from the current location to the destination and weather conditions are known, the DC-DC converter stops working again, prioritizing solar power for low-voltage loads. If the solar power output is sufficient, it can also charge the battery until the vehicle reaches its destination and stops. If the solar power output decreases during this process and is insufficient to maintain the vehicle's low-voltage loads, the battery can then provide low-voltage power.

[0077] In actual implementation, such as Figure 5 As shown, Figure 5 A flowchart for coordinating solar power replenishment and high-voltage battery power replenishment.

[0078] S501, when the system determines that it has received a request for power replenishment, the system needs to obtain the illumination conditions of the environmental sensing unit, calculate the available output power of solar energy, and estimate the future available duration of solar energy based on weather conditions.

[0079] S502, simultaneously based on vehicle load power, current battery charge, and target battery charge.

[0080] S503 also requires information on the high-voltage battery pack charge and available output power.

[0081] S504, if the available output power of solar energy is greater than a certain threshold (such as the low-voltage load power of the vehicle within a certain period of time or a fixed value of 1kW), and the future available duration threshold of solar energy is greater than a certain threshold (such as 6 hours).

[0082] S505 If the available output power of solar energy is greater than a certain threshold (such as the low-voltage load power of the vehicle within a certain period of time or a fixed value of 1kW), and the future available duration of solar energy is greater than a certain threshold (such as 6 hours), then solar energy will be used for supplementary power generation.

[0083] S506 If the conditions are not met, it is determined that the available power of the high-voltage battery is greater than a certain threshold (such as the low-voltage load power of the vehicle within a certain period of time or a fixed value of 5kw), and the available power of the high-voltage battery pack is greater than the threshold (such as 20%).

[0084] S507: If the conditions are not met, it is determined that the available power of the high-voltage battery is greater than a certain threshold (such as the vehicle's low-voltage load power within a certain period of time or a fixed value of 5kW), and the available charge of the high-voltage battery pack is greater than a threshold (such as 20%). In this case, the high-voltage battery pack is used for recharging.

[0085] If the requirements are not met, the S508 will send a charging reminder to the owner. The charging process will end once the available battery power exceeds the target charging level.

[0086] Under the condition that the vehicle's destination is known, and that there will be sufficient sunlight and battery charge in the near future, the high-voltage battery pack is replenished via a reversible DC-DC converter. After parking, low-voltage power is supplied by solar energy. During the vehicle's journey, real-time navigation information is acquired. If the destination and weather conditions are known, and the weather conditions are favorable, the high-voltage battery pack is replenished using solar energy and the existing battery before the trip ends. Upon arrival at the destination and parking, solar energy is used to power the vehicle's low-voltage load and charge the battery.

[0087] In actual implementation, such as Figure 6 As shown, Figure 6 This is a flowchart illustrating how solar energy and batteries can be used to replenish the high-voltage battery pack during operation.

[0088] S601, the vehicle is currently in motion.

[0089] S602 obtains current lighting conditions, battery level, solar power conditions, load power, etc.

[0090] S603, obtain the duration of illumination at the destination and upon arrival at the destination.

[0091] S604 determines the battery charge, the difference between the average available solar power output and the average vehicle load power, the available solar power duration during the current trip, and the sunshine duration after arriving at the destination. If the above conditions are not met, a hybrid power supply method using solar energy and high-voltage battery pack is used.

[0092] If S605 is met, the DC-DC converter will stop working and only use solar power for supplemental power if the current trip does not involve solar power replenishment.

[0093] S606, at this point, further determine the current battery charge, the difference between the average available solar power output and the average vehicle load power, the available solar power duration for the current trip, and the sunshine duration after arriving at the destination.

[0094] S607, if the conditions are still met, then enter the DC-DC startup mode to use solar energy and batteries to compensate the high-voltage battery pack. This function can only be entered once per cycle.

[0095] S608, if the charging conditions are not met, exit.

[0096] Optionally, in some embodiments, after obtaining the current vehicle's operating state, the method further includes: when the operating state is a parked state, if the current vehicle is woken up, obtaining the current vehicle's current location, current average load power, fourth available duration of solar energy at the current location, second available average power of solar energy, and third available charge of the battery; when the third available charge is greater than a fourth preset charge, the difference between the second available average power and the current average load power is greater than a third preset threshold, and the fourth available duration is greater than a sixth preset duration, replenishing the battery with solar energy; when the third available charge is greater than a fifth preset charge, the difference between the second available average power and the current average load power is greater than a fourth preset threshold, and the fourth available duration is greater than a seventh preset duration, replenishing the high-voltage battery pack with solar energy and the battery, wherein the fifth preset charge is greater than the fourth preset charge, the fourth preset threshold is greater than the third preset threshold, and the seventh preset duration is greater than the sixth preset duration.

[0097] Specifically, when the vehicle is parked and in good lighting conditions, if a battery recharging request is needed, solar power will be used first. In low lighting conditions, the high-voltage battery pack will be used first. When the vehicle is in sleep mode, if a battery recharging request is received, solar power will be used first in good lighting conditions. In low lighting conditions, the high-voltage battery pack will be used in addition.

[0098] When the vehicle is parked and there is sufficient sunlight, the solar power supply is sufficient to power the low-voltage load, and the DC-DC converter stops operating. If the sunlight is exceptionally good and the battery has sufficient charge, the high-voltage battery pack can be replenished via the reversible DC-DC converter. When the vehicle is parked, if the battery has sufficient charge and the solar conditions are favorable for a period of time, the solar charging power can be sufficient to power the vehicle's low-voltage load. Solar energy and the battery can then be used to replenish the high-voltage battery pack via the reversible DC-DC converter.

[0099] In actual implementation, such as Figure 7 As shown, Figure 7 This is a flowchart illustrating the operation of the DC-DC converter and the feedback of the high-voltage battery pack in a stopped state.

[0103] S704, Current location's solar energy availability time

[0104] The S705 determines the available solar power output by analyzing the difference between the battery charge, the average available solar power output, and the average power output of the vehicle load, as well as the available solar power duration at the current location. If these conditions are not met, the system maintains the hybrid charging mode.

[0105] S706: If the conditions are met, the DC-DC converter will stop working and enter the solar power supplement mode.

[0106] The S707 further assesses factors such as battery charge, the difference between the average available solar power output and the average power output per vehicle load, and the duration of available solar power at the current location.

[0107] S708, if the conditions are still met, then enter the DC-DC reverse compensation high voltage battery pack function.

[0108] S709 If the conditions are not met, the power replenishment process will be terminated.

[0109] Optionally, in some embodiments, the above-described vehicle battery power distribution method further includes: determining the current timing duration and judging whether the current time is sunrise; if the current time is sunrise, obtaining the light intensity at the current location, the minimum safe power value of the battery, and / or the target replenishment power value of the battery; receiving the available light duration conditions of future weather in real time, and calculating the available light ratio within a preset future time period based on the light intensity at the current location and the available light duration conditions of future weather; obtaining the minimum safe power correction value from a preset light ratio-safe power correction value table based on the available light ratio, and / or, based on the available light ratio from a preset... The minimum replenishment power correction value is obtained from the light ratio-safe power correction value table; the minimum safe power value is corrected according to the minimum safe power correction value, and / or the target replenishment power value is corrected based on the minimum replenishment power correction value, and it is determined whether the current timeout duration has been reached after the correction; if the current timeout duration has not been reached, it is re-determined whether the current time is sunrise, otherwise, it is determined whether the current time is sunset; if the current time is sunset, the minimum safe power value of the battery is restored to the first preset value and / or the target replenishment power value of the battery is restored to the second preset value, otherwise, the current timeout duration is re-determined until the current time is sunset.

[0110] Specifically, based on future sunlight conditions, the available duration of solar energy is determined in real time, and the target battery charging capacity is comprehensively determined based on this available duration. Specifically, when the vehicle is awake, the available sunlight duration conditions for future weather are received in real time, and the available sunlight duration is calculated. The target battery charging capacity is determined based on the available sunlight duration; the longer the available duration, the lower the target battery charging capacity threshold; conversely, the shorter the duration, the higher the target battery charging capacity threshold.

[0111] In actual implementation, such as Figure 8 As shown, Figure 8 This is a flowchart for calculating the target replenishment capacity of the battery based on certain conditions.

[0112] S801 sets a timer to update the target battery charge level periodically, only updating it between sunrise and sunset.

[0122] Battery 901 is responsible for supplying power to the electronic control unit that requires functions after the vehicle is started or locked, or for supplying power to the electronic control unit before high voltage is applied after the vehicle is unlocked.

[0123] The reversible DC-DC902 is responsible for the mutual conversion of high-voltage and low-voltage power supply energy through internal switching circuits;

[0124] The high-voltage battery pack 903 is responsible for storing and outputting high-voltage power.

[0125] Power module 904 is responsible for rectifying, modulating, and processing the output power of the solar panel;

[0126] Solar panel 905 is responsible for converting solar energy into electrical energy and outputting it to the power module;

[0127] The solar panel control unit 906 is responsible for communicating with the vehicle control system and for real-time monitoring and control of the solar panel actuators.

[0128] The remote control unit 907 is mounted on the vehicle and communicates with the cloud platform, while also being responsible for activating remote functions;

[0129] Cloud platform 908 is responsible for processing and transmitting backend information, connecting mobile terminals and remote control units;

[0130] Mobile terminal 909 is responsible for providing information to the vehicle owner and inputting settings for remote functions;

[0131] The central control unit 910 is responsible for the functional management and coordination of all controllers in the vehicle;

[0132] The intelligent driving domain control unit 911 is responsible for the functional control of the vehicle's intelligent driving domain and communicates with the central controller.

[0133] Navigation map unit 912 is responsible for obtaining customer navigation information, such as customer destination and travel time;

[0134] The intelligent cockpit domain control unit 913 is responsible for the functional control of the vehicle's intelligent cockpit domain and communicates with the central controller.

[0135] The environmental sensing unit 914 is responsible for acquiring information about conditions such as weather or lighting.

[0136] Vehicle low-voltage load 915 includes all low-voltage electrical loads of the vehicle, including modules, actuators, sensors, etc.

[0137] The power domain control unit 916 is responsible for the functional control of the power domain and communicates with the central controller.

[0138] The intelligent power distribution unit 917 is responsible for distributing and managing all power supplies for the vehicle's load.

[0139] The DC-DC control unit 918 is responsible for detecting the working status and controlling the function of the reversible DC-DC converter.

[0140] The high-voltage battery pack control unit 919 is responsible for controlling the input and output and status detection of the high-voltage battery pack according to instructions.

[0141] Therefore, this application seems to eliminate the need for a battery current sensor; it uses the controller port to monitor the current of its own and the interface's electrical load in real time, estimates the battery charge change trend after the vehicle is powered off, and sets a timer to wake up the vehicle for recharging. (If the controller port has E-fuse functionality, it can still monitor the port current in real time after power-off, eliminating the need for a timer to wake it up); simultaneously, through the coordination of solar recharging and high-voltage recharging functions, it intelligently allocates the vehicle's energy consumption from the battery; it also considers that when solar recharging conditions are good, the battery is prioritized for consumption before parking, and after power-off, solar recharging becomes the main low-voltage power supply for the vehicle, in order to save vehicle energy; during driving and parking, if the battery and its energy are sufficient, the battery is used to recharge the high-voltage battery.

[0142] According to the vehicle battery power distribution method proposed in this application, by acquiring the current operating status of the vehicle, the method coordinates the use of solar energy and high-voltage battery power under different operating conditions. When sunlight conditions are good, solar energy is prioritized for supplementing power, reducing DC-DC power supply. Solar energy powers the vehicle load and battery. Simultaneously, if the battery has sufficient charge, it can also supplement the high-voltage battery. If sunlight conditions are good, the battery is charged through the DC-DC high-voltage battery. Furthermore, the method protects the battery's safe charge level based on weather conditions. This solves the problems of related technologies that cannot accurately estimate battery charge and that periodically waking the vehicle increases the possibility of battery depletion, thus maximizing the efficiency of battery energy utilization and preventing battery depletion.
