[0002] With technological advancements, automobiles are becoming increasingly versatile, providing technical support for safe, comfortable, and convenient travel. Cars are equipped with numerous functional components to operate these diverse functions, and these components must be activated to access their corresponding functions. Current automotive technologies typically require drivers or passengers to activate these components one by one. This requires familiarity with the specific operating procedures of each component, preventing them from accessing the corresponding functions. Furthermore, the user experience is cumbersome and can easily lead to users giving up on the process, effectively preventing them from using the function. Furthermore, these components typically require electric power to operate and provide their functions. However, electric vehicles have limited energy storage capacity, and the operation of some high-powered components will deplete the energy storage capacity of driving-related components, such as the motor, resulting in reduced range.

[0055] In this embodiment, the electric vehicle control method can be applied to Figure 1 In the vehicle system shown. Figure 1 The vehicle-mounted system includes a control module, a power module, a battery management system (BMS), a power battery, and n vehicle function modules. The vehicle-mounted system can be installed in an electric vehicle, which can be a pure electric vehicle or a hybrid electric vehicle. This embodiment uses a pure electric vehicle as an example.

[0056] Reference Figure 1 The automotive functional modules are power-consuming components installed in electric vehicles to perform various specific functions, such as the motor for driving the electric vehicle, the audio and video entertainment system for entertainment, ambient lighting for climate control, windshield wipers for windshield cleaning, and windows and motors for adjustable windows. In this embodiment, two typical components with high power consumption are used as specific examples of automotive functional modules: a battery heating module (automotive functional module 1) for heating and maintaining the power battery, and an air conditioner (automotive functional module 2) for regulating the cabin temperature.

[0057] In this embodiment, refer to Figure 1 The power module includes an external connection interface that allows it to be connected to an external charging device, such as a charging station. The power module has functions such as switching, voltage conversion, current limiting, and frequency conversion. For example, it can split the current (power supply energy) provided by the charging station into two paths: one path forms charging power and is provided to the battery management system, which then charges the power battery; the other path forms functional power and is provided to various vehicle functional modules, thereby driving the vehicle functional modules to operate and realize their corresponding functions.

[0058] In this embodiment, each step in the electric vehicle control method can be executed by the control module. Figure 2 , the electric vehicle control method includes the following steps:

[0059] S1. Obtain at least one vehicle function usage task;

[0060] S2. Detect charging ready signal;

[0061] S3. When a charging ready signal is detected, power is obtained from an external charging device;

[0062] S4 responds to the charge ready signal, executes each vehicle function using the task;

[0063] S5. Use the supplied electrical energy to power functional components of the vehicle and charge the power battery.

[0064] In step S1, the vehicle function usage task is a task executed by the control module calling the corresponding vehicle function component. For example, in this embodiment, step S1 can set the following vehicle function usage tasks:

[0065] Vehicle function usage task 1: The battery heating module (vehicle function module 1) performs heating and heat preservation on the power battery

[0066] Vehicle Function Usage Task 2: Use the air conditioner (vehicle function module 2) to adjust the temperature in the cockpit

[0067] When executing step S1 , various automobile function usage tasks manually set by the automobile user may be obtained through the human-computer interaction module, or the automobile function usage tasks that need to be executed may be automatically determined by the control module.

[0068] In this embodiment, when executing step S1, that is, obtaining at least one automobile function usage task, the following steps may be specifically performed:

[0069] S101. Obtain travel plan information;

[0070] S102. Determine at least one vehicle function usage task based on the travel plan information.

[0071] The process of steps S101-S102 is as follows: Figure 3 As shown. Figure 3 , you can automatically set the usage tasks of various car functions through the "Smart Travel" function.

[0072] In step S101, the travel plan information is information related to a future trip (e.g., 30 minutes or 1 hour from now) that the vehicle user intends to take in an electric vehicle. This travel plan information may include the departure point, destination, route, departure time, estimated arrival time, and weather conditions along the way. Specifically, the vehicle user may set navigation information, and the control module may then query information such as weather conditions along the way from sources such as the internet based on the navigation information to obtain the travel plan information.

[0073] Reference Figure 3 After executing step S101 to obtain the travel plan information, the control module can estimate the remaining time T from the current departure time based on the departure time in the travel plan information. go , based on the route in the travel plan information, estimate the specified amount of electricity required for the electric vehicle to complete the journey, and then estimate the time T required to charge the power battery to the specified amount of electricity 充电 The control module can estimate the optimal temperature in the cockpit to ensure safe and comfortable driving of the electric vehicle based on the weather along the way in the travel plan information, and then estimate the time T required to heat or cool the cockpit to the optimal temperature. 空调 ; and take T 计时 =max{T 充电 , T 空调}, if T go <T 计时 , indicating that it is not enough to charge the power battery to the specified power before the electric vehicle sets off, nor is it enough to heat or cool the cabin to the optimal temperature, then no car usage task can be set; if T go ≥T 计时 , indicating that before the electric vehicle sets off, the power battery can be charged to a specified amount of power and the temperature in the cockpit can be heated or cooled to an optimal temperature, so the vehicle usage task 1 and the vehicle usage task 2 are set.

[0074] After step S1, step S2 is executed. The charge-ready signal detected in step S2 indicates that the power module has found a reliable external power source and has met the hardware requirements for receiving external power. When the charge-ready signal is detected, the power module enters a ready state and temporarily stops receiving external power. It continues to wait for instructions and only receives external power after receiving instructions.

[0075] For example, a sensor can be installed in the charging gun interface of the power module to detect whether the charging gun is inserted (the sensor outputs a signal if the charging gun is inserted, and no signal if the charging gun is not inserted). Insertion of the charging gun into the charging gun interface of the power module indicates that the power module is connected to the external charging device (charging pile) and meets the hardware requirements for receiving external power. However, it is not currently receiving power from the external charging device (charging pile) and can wait for further instructions to start receiving power. Therefore, in this embodiment, the signal output by the charging gun sensor can be used as the charging ready signal to be detected. The charging ready signal is detected when the charging gun is inserted into the charging gun interface of the power module.

[0076] In step S2, if the charge ready signal is not detected, steps S3-S5 are not triggered, but step S2 is continuously executed in a loop until the charge ready signal is detected, and then the process jumps to step S3 and other steps.

[0077] In case the charge ready signal is detected, steps S3 and S4 are executed.

[0078] In step S3, the control module may send an instruction to the power module, thereby turning on a switch in the power module, so that the power provided by the external charging device (charging pile) can be input into the power module.

[0079] The power module decomposes the supplied electrical energy into charging energy and functional electrical energy. It transmits the charging energy to the battery management system and transmits the functional electrical energy to the vehicle functional modules that need to perform vehicle functional tasks.

[0080] In steps S4-S5, the control module sends instructions to the battery heating module (automobile function module 1), and the battery heating module (automobile function module 1) obtains the drive of functional electrical energy, thereby executing automobile function usage task 1 and heating and keeping the power battery warm; the control module sends instructions to the air conditioner (automobile function module 2), and the air conditioner (automobile function module 2) obtains the drive of functional electrical energy, thereby executing automobile function usage task 2 and adjusting the temperature of the cockpit; the control module sends instructions to the battery management system, and the battery management system charges the charging energy into the power battery.

[0081] In this embodiment, by executing steps S1-S5, at least one vehicle function usage task that needs to be executed before the electric vehicle travels can be set through functions such as "Smart Travel", and the execution of each vehicle function usage task can be triggered by a charging ready signal (specifically, the insertion of a charging gun). The vehicle functional components that execute the vehicle function usage tasks can share the power supply energy from the external charging device with the charging process of the power battery; on the one hand, it is realized that the execution of a series of vehicle function usage tasks is triggered by the common vehicle usage actions such as plugging in the charging gun, and the batch call of multiple vehicle functional components is realized, which simplifies the operation process of the vehicle functional components and improves the convenience of vehicle use; on the other hand, the "Smart Travel" function can be used to set the functions that need to be pre-set before driving. The vehicle function usage tasks that are executed first (for example, the battery heating module heats the power battery in advance, the air conditioner heats or cools the cockpit in advance, etc.) can create a suitable driving environment in advance, so that the driver can obtain safe and comfortable driving conditions when driving, reducing waiting time; thirdly, the vehicle function usage tasks with high energy consumption of the vehicle function module can be arranged to be executed, so that the power supply provided by the external charging equipment (charging pile) can provide the necessary power supply for the vehicle function module to execute the vehicle function usage tasks. When the usage of the vehicle function usage tasks is the same, the time for the power battery to supply energy to the vehicle function module is reduced, which is beneficial to reduce the discharge loss of the power battery, protect the service life of the power battery, and ensure the endurance performance of the electric vehicle.

[0082] In this embodiment, when executing step S4, that is, executing each vehicle function usage task, the following steps may be specifically performed:

[0083] S401 obtains each vehicle function usage task corresponding to the vehicle function usage power consumption;

[0084] S402. Determine the execution order of each vehicle function using the power consumption of each vehicle function;

[0085] S403. Execute each vehicle function usage task in sequence according to the determined execution order.

[0086] In step S401, the vehicle function usage power consumption is the power consumption of the vehicle function components performing the corresponding vehicle function usage tasks during operation. The vehicle function usage power consumption can be expressed in the form of power (units such as kW) or the amount of energy consumed over a certain period of time (units such as kWh).

[0087] In step S401, the vehicle function usage power consumption can be expressed as the average power or rated power of the vehicle function components. For example, in this embodiment, vehicle function usage task 1 is performed by the battery heating module (vehicle function module 1), and the average power of the battery heating module (vehicle function module 1) may be 0.1kW. Therefore, the vehicle function usage power consumption corresponding to vehicle function usage task 1 is 0.1kW. Vehicle function usage task 2 is performed by the air conditioning (vehicle function module 2), and the average power of the air conditioning (vehicle function module 2) may be 3kW. Therefore, the vehicle function usage power consumption corresponding to vehicle function usage task 2 is 3kW.

[0088] In this embodiment, it is assumed that the following vehicle function usage tasks are also performed in step S1:

[0089] Car function usage task 3: Cooking is performed by the car cooking module (car function module 3)

[0090] In step S401 , the average power of the vehicle cooking module (vehicle function module 3 ) may be 5 kW, so the vehicle function usage power consumption corresponding to vehicle function usage task 3 is 5 kW.

[0091] In step S402, the execution order of each vehicle function usage task can be determined in descending order of the power consumption of each vehicle function. For example, in the above-mentioned vehicle function usage task 1, vehicle function usage task 2, and vehicle function usage task 3, the execution order determined according to the descending order of the power consumption of the vehicle functions is:

[0092] Vehicle function usage task 3 (5kW), vehicle function usage task 2 (3kW), vehicle function usage task 1 (0.1kW)

[0093] In step S403, the vehicle function usage tasks can be executed sequentially in the order of vehicle function usage task 3, vehicle function usage task 2, and vehicle function usage task 1. Specifically, the control module can call the in-vehicle cooking module (vehicle function module 3) to execute vehicle function usage task 3 to complete cooking. It can then call the air conditioning module (vehicle function module 2) to execute vehicle function usage task 2, heating or cooling the cabin temperature to the target temperature, thereby completing vehicle function usage task 2. Finally, it can call the battery heating module (vehicle function module 1) to execute vehicle function usage task 1.

[0094] In this embodiment, when executing step S402 , in addition to comparing the power consumption of each vehicle function individually, the power consumption of multiple vehicle functions may be combined for comparison.

[0095] For example, in step S402, a maximum power (for example, 5kW) can be set based on factors such as the hardware performance or safety limitations of the power module, and the power consumption of each of the vehicle function usage task 3, the vehicle function usage task 2, and the vehicle function usage task 1 can be combined, and the power consumption combination obtained does not exceed the maximum power.

[0096] Among them, since the car function usage power consumption (5kW) corresponding to car function usage task 3 has reached the maximum power, the car function usage power consumption (5kW) corresponding to car function usage task 3 can only form a power consumption combination alone; while the car function usage power consumption (0.1kW) corresponding to car function usage task 1 and the car function usage power consumption (3kW) corresponding to car function usage task 2 can form a power consumption combination, the size of which is the sum of the car function usage power consumptions in the power consumption combination, that is, 3.1kW.

[0097] Thus, in step S402, the ranking is performed based on the power consumption combination, and the resulting ranking is:

[0098] Vehicle function usage task 3 (5kW), [vehicle function usage task 2 (3kW) and vehicle function usage task 1 (0.1kW)]

[0099] Thus, when executing step S403, vehicle function usage task 3 corresponds to a single power consumption combination, and its power consumption is the highest and ranked first. Therefore, the control module can first call the in-vehicle cooking module (vehicle function module 3) to execute vehicle function usage task 3. After vehicle function usage task 3 is completed, the control module calls the next power consumption combination, which corresponds to two vehicle function usage tasks, namely vehicle function usage task 2 and vehicle function usage task 1. The control module can simultaneously call the battery heating module (vehicle function module 1) and the air conditioning module (vehicle function module 2) to execute vehicle function usage tasks 1 and 2.

[0100] In this embodiment, by executing steps S401-S403, high-power vehicle function modules are prioritized to execute corresponding vehicle function tasks. This fully utilizes the power provided by external charging equipment (charging piles) and reduces the power consumption of the power battery by these high-power vehicle function modules, thereby protecting the power battery's service life and ensuring the electric vehicle's endurance. Furthermore, when the maximum power is limited, multiple vehicle function modules corresponding to different power consumption combinations can be simultaneously invoked to execute multiple vehicle function tasks, improving the efficiency of executing vehicle function tasks while ensuring safety.

[0101] In this embodiment, when the control module executes step S5, that is, the step of supplying power to the functional components of the vehicle and charging the power battery, the control module may specifically execute the following steps:

[0102] S501A. Obtain the respective automobile function use power consumption of each automobile function use task;

[0103] S502A. Determine the function power consumption according to the sum of the respective automobile function use power consumption;

[0104] S503A. Decompose the power supply power into function power consumption and charging power;

[0105] S504A. Power the automobile function components with the function power consumption, and charge the power battery with the charging power.

[0106] Steps S501A-S504A are a first execution manner of step S5.

[0107] Step S501A is the same as step S401.

[0108] In step S502A, the sum of the respective automobile function use power consumption is determined as the function power consumption, that is, the power (power or energy) that the power supply module needs to provide to all automobile function modules.

[0109] In steps S503A-S504A, the control module controls the power supply module to decompose the power supply power into function power consumption and charging power through switching and other operations. Moreover, the power supply module preferentially allocates the power supply power to the function power consumption, so that the size of the function power consumption reaches the value determined in step S502A, and the remaining part of the power supply power that is not allocated to the function power consumption is delivered to the battery management system as charging power, and is charged into the power battery by the battery management system.

[0110] In this embodiment, by executing steps S501A-S504A, the charging power provided by the external charging device (charging pile) can be preferentially guaranteed for each automobile function module to execute the automobile function use task, so that each automobile function module executes the automobile function use task more using the power provided by the external charging device (charging pile), reduces the use of the power battery, is beneficial to protect the service life of the power battery, and guarantees the endurance performance of the electric vehicle.

[0111] In this embodiment, when the control module executes step S5, that is, the step of powering the automobile function components with the power supply power and charging the power battery, the following steps can be executed:

[0112] S501B. Obtain the travel plan information;

[0113] S502B. Determine the decomposition ratio according to the travel plan information;

[0114] S503B according to the decomposition ratio, the power supply is decomposed into functional power energy and charging power;

[0115] S504B. Use functional electrical energy to power functional components of the vehicle, and use charging electrical energy to charge the power battery.

[0116] Steps S501B-S504B are a second execution method of step S5.

[0117] Step S501B is the same as step S101.

[0118] In step S502B, the decomposition ratio can be determined based on information such as the route and weather conditions along the way in the travel plan information. Specifically, the control module can estimate the amount of power required for the electric vehicle to complete the journey based on the route, thereby determining the first amount of power. The control module can also estimate the appropriate target power battery temperature and target cabin air temperature based on the weather along the way, and estimate the amount of power required to operate the battery heating module (vehicle functional module 1) and the air conditioning module (vehicle functional module 2) to achieve the target power battery temperature and cabin air temperature, thereby determining the second amount of power.

[0119] In step S502B, the formula

[0120] k1=first charge / (first charge + second charge)

[0121] k2=second charge / (first charge + second charge)

[0122] To determine the decomposition ratios k1 and k2.

[0123] In step S503B, the formula

[0124] Charging energy = power supply energy × k1

[0125] Functional power consumption = power supply energy × k2

[0126] Thus, the amount of charging energy and functional power can be calculated.

[0127] In steps S503B-S504B, the control module controls the power module and decomposes the power supply energy into functional power energy and charging power energy through operations such as switches. The functional power energy is used to drive vehicle functional modules such as the battery heating module (vehicle functional module 1) and the air conditioner (vehicle functional module 2), and the power supply energy is charged into the power battery by the battery management system.

[0128] In this embodiment, by executing steps S503B-S504B, the charging demand of the power battery and the power demand of each vehicle functional module can be determined according to the travel plan information, so as to determine the decomposition ratio to decompose the power supply energy into charging power and functional power, so that the charging demand of the power battery and the power demand of each vehicle functional module can be met at the same time, avoiding the situation where the power battery is not charged due to the charging time of the external charging equipment (charging pile) being too short.

[0129] In this embodiment, when the control module executes step S504A or S504B, that is, the step of powering the functional components of the vehicle with functional power energy and charging the power battery with charging power energy, the control module may specifically execute the following steps:

[0130] S50401. Obtain standard performance curve and standard charging curve;

[0131] S50402. Obtain the actual performance curve and the actual charging curve;

[0132] S50403. According to the actual performance curve and the actual charging curve, the standard performance curve and the standard charging curve are corrected to obtain a corrected performance curve and a corrected charging curve;

[0133] S50404. According to the modified performance curve, the functional electric energy is used to drive the functional components of the vehicle to work;

[0134] S50405. Charge the power battery with the charging energy according to the modified charging curve.

[0135] In steps S50401-S50402, the obtained standard performance curve and actual performance curve are in the form of Figure 4 As shown, the obtained standard charging curve and actual charging curve are in the form of Figure 5 shown.

[0136] In this embodiment, Figure 4 and Figure 5 The time axis in the diagram can unify the origin and scale. The origin can be the start-up time of the vehicle functional module, or the time when the battery management system starts charging the power battery.

[0137] Taking air conditioning (automotive functional module 2) as an example, refer to Figure 4The standard performance curve represents the correspondence between the target performance parameters (e.g., cooling temperature) of the air conditioner (automotive functional module 2) and time. A point on the standard performance curve represents the ideal temperature to which the cockpit is regulated by the air conditioner (automotive functional module 2) through cooling at the time corresponding to that point. The actual performance curve represents the correspondence between the actual performance parameters and time generated by the air conditioner (automotive functional module 2) during past operation. For example, the actual temperature to which the cockpit was regulated by cooling at each point in time during the last operation of the air conditioner (automotive functional module 2).

[0138] Similarly, refer to Figure 5 The standard charging curve represents the corresponding relationship between the target state of charge (SOC) of the power battery and time. A point on the standard performance curve represents the SOC value that the power battery would be charged to at the time corresponding to this point under ideal conditions. The actual performance curve represents the corresponding relationship between the actual state of charge (SOC) reached by the power battery during previous charging and time. For example, the SOC value that the power battery was actually charged to at each time point during the last charging.

[0139] In this embodiment, the actual performance curve and the standard performance curve generally do not overlap, but there is a deviation. Figure 4 The actual performance curve achieved by the air conditioner (automotive functional module 2) during cooling is generally higher than the standard performance curve. This is because the air conditioner (automotive functional module 2) deviates from the ideal performance due to aging and other reasons, resulting in the actual temperature reached in the cockpit through cooling at each time point being higher than the ideal temperature.

[0140] Similarly, the actual charging curve and the standard charging curve are generally not coincident, but there is a deviation. Figure 5 The actual charging curve reached when the power battery is charged is generally lower than the standard charging curve. This is because the power battery deviates from the ideal performance due to aging and other reasons, resulting in the state of charge (SOC) being lower than the ideal state of charge (SOC) at each time point.

[0141] Due to the aging of automotive functional modules, it is not appropriate to directly control their operation according to the standard performance curve. Instead, the standard performance curve can be modified to obtain a modified performance curve, and the automotive functional modules can be controlled according to the modified performance curve. Similarly, due to the aging of power batteries, it is not appropriate to directly charge them according to the standard charging curve. Instead, the standard charging curve can be modified to obtain a modified charging curve, and the power batteries can be charged according to the modified charging curve.

[0142] In this embodiment, when executing step S50403, that is, correcting the standard performance curve and the standard charging curve based on the actual performance curve and the actual charging curve to obtain the corrected performance curve and the corrected charging curve, the following steps may be performed:

[0143] S5040301. According to the actual performance curve and the standard performance curve, determine the first offset value;

[0144] S5040302. Determine a second offset value based on the actual charging curve and the standard charging curve;

[0145] S5040303. Determine a third offset value based on the first offset value and the second offset value; the third offset value is positively correlated with the first offset value and negatively correlated with the second offset value;

[0146] S5040304. Determine a fourth offset value based on the first offset value and the second offset value; the fourth offset value is positively correlated with the second offset value and negatively correlated with the first offset value;

[0147] S5040305. Correct the standard performance curve according to the third offset value to obtain a corrected performance curve;

[0148] S5040306. Correct the standard charging curve according to the fourth offset value to obtain a corrected charging curve.

[0149] In step S5040301, refer to Figure 4 , the area enclosed by the actual performance curve and the standard performance curve (i.e. Figure 4 In the shaded portion, if the actual performance curve and the standard performance curve are not connected end to end, the area S1 between the actual performance curve and the standard performance curve on the vertical axis can be calculated as the first offset value.

[0150] Similarly, in step S5040302, refer to Figure 5 , the area enclosed by the actual charging curve and the standard charging curve (i.e. Figure 5 The shaded portion in FIG. 5 is used as the second offset value S2. In this embodiment, the first offset value S1 and the second offset value S2 are both absolute values.

[0151] In steps S5040303-S5040304, a third offset value S3 and a fourth offset value S4 are calculated based on the first offset value S1 and the second offset value S2, and the third offset value S3 is positively correlated with the first offset value S1 and negatively correlated with the second offset value S2, and the fourth offset value S4 is positively correlated with the second offset value S2 and negatively correlated with the first offset value S1. In this embodiment, the third offset value S3 and the fourth offset value S4 can be calculated using the following formula:

[0152] S3 = S1 / (S1 + S2)

[0153] S4 = S2 / (S1 + S2)

[0154] In step S5040305, the standard performance curve is modified according to the third offset value S3 to obtain a modified performance curve. Specifically, since the purpose of the modified performance curve is to reduce the performance requirement on the automobile functional module, with reference to the target performance parameter, if the target performance parameter is a performance parameter such as "cooling temperature" whose value is lower and whose performance requirement is higher, each value on the standard performance curve can be multiplied by the third offset value S3 to obtain a new larger value to form the modified performance curve. If the target performance parameter is a performance parameter such as "heating temperature" whose value is higher and whose performance requirement is higher, each value on the standard performance curve can be divided by the third offset value S3 to obtain a new smaller value to form the modified performance curve. Figure 6

[0155] Similarly, in step S5040306, the standard charging curve is modified according to the fourth offset value S4 to obtain a modified charging curve. Specifically, since the purpose of the modified charging curve is to reduce the performance requirement on the power battery, with reference to the target performance parameter, if the target performance parameter is a performance parameter such as "cooling temperature" whose value is lower and whose performance requirement is higher, each value on the standard charging curve can be divided by the fourth offset value S4 to obtain a new smaller value to form the modified charging curve. Figure 7

[0156] After the modified performance curve and the modified charging curve are obtained in step S50403, steps S50404-S50405 are performed to drive the automobile functional components using the functional electric energy according to the modified performance curve, that is, to control the performance release of the automobile functional components to meet the requirement of the modified performance curve, and to charge the power battery according to the modified charging curve, that is, to control the charging speed of the power battery to meet the requirement of the modified charging curve.

[0157] ​​In this embodiment, the principle of executing steps S5040301-S5040306 is: taking the correction of the standard performance curve as an example, the third offset value S3 used to correct the standard performance curve is positively correlated with the first offset value S1, that is, the greater the deviation of the actual performance curve from the standard performance curve (indicating that the degree of aging of the functional components of the automobile is greater), the greater the correction amplitude of the standard performance curve (in the direction of reducing the performance requirements), thereby making the performance margin of the functional components of the automobile greater and being able to adapt to the current status of performance aging of the functional components of the automobile; at the same time, the third offset value S3 used to correct the standard performance curve is negatively correlated with the second offset value S2, that is, the greater the deviation of the actual charging curve from the standard charging curve (indicating that the degree of aging of the power battery is greater, the charging control of the power battery is greater). , the greater the performance tolerance for the power battery), the smaller the correction range of the standard performance curve (in the direction of reducing performance requirements), thereby making the performance tolerance for automobile functional components smaller; the correction of the standard charging performance curve is also based on a similar principle, that is, the greater the degree of aging of the power battery, the greater the performance tolerance for the power battery, which can adapt to the current status of power battery performance aging, but the greater the degree of aging of automobile functional components, the more limited the performance tolerance for the power battery; in this way, it is possible to achieve adaptation between the functional use of automobile functional components and the current status of charging and performance aging of the power battery, and the performance tolerance for automobile functional components and the performance tolerance for power batteries can be mutually restrained, so as to avoid the performance tolerance for automobile functional components and the performance tolerance for power batteries being too large and affecting the performance of the entire vehicle.
