At present, after the vehicle is parked and powered off, many electronic control units on the vehicle still have dormant power consumption. If the vehicle is parked for too long, the battery used to power the electronic control unit will always be in a feeding state, eventually leading to a battery power shortage problem, which will cause the vehicle to be unable to start normally, and then cause the vehicle to be unable to work. Summary of the invention

When the charging request of the intelligent charging system is not received within a period of time, it is considered that the intelligent charging system is abnormal and cannot send a charging request to the vehicle-mounted controller. At this time, the control module controls the vehicle-mounted controller to control the power battery system to charge the battery.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0038] The current battery charging method is to automatically wake up the intelligent charging controller at a predetermined period. When in the wake-up period, the battery voltage is monitored. When the battery voltage is less than the battery charging start voltage, the intelligent charging controller starts working and controls the power battery to charge the battery. However, if the intelligent charging controller fails abnormally, it is impossible to control the power battery to charge the battery, so that the battery still has the risk of power feeding.

[0039] This application adopts a mutually redundant approach between the intelligent charging system and the vehicle-mounted controller. In the event of an abnormal failure of the intelligent charging system, the vehicle-mounted controller directly controls the power battery system to charge the battery, and the battery charging control can still be completed, thereby reducing the risk of battery power feeding, increasing the battery service life, and improving the user experience.

[0040] For the convenience of explanation, the following embodiments are combined Figure 1 The vehicle charging control method of the present application is described.

[0041] Reference Figure 1 The battery charging control method of the vehicle in the present application may include the following steps:

[0042] S101, when the onboard controller of the vehicle is in the awake state, obtaining parameters of the battery.

[0043] S102: When it is determined according to the battery parameters that a preset charging condition is met and no charging request from the vehicle's intelligent charging system is received, it is determined that a fault occurs in the intelligent charging system.

[0044] S103, when the intelligent charging system fails, the power battery system of the vehicle is controlled to charge the battery according to the parameters of the battery.

[0045] Specifically, the vehicle's on-board controller is in an automatic wake-up state when a certain period of time is reached. The smart charging system can be awakened according to the acquired time interval or by hardware triggering. The hardware triggering method can be to output a high-level signal when the battery voltage is less than the charging voltage value to put the smart charging system in an awake state.

[0046] When the vehicle's onboard controller is in the awake state, the battery parameters are obtained, where the battery parameters may include the battery voltage value, the battery power, etc. When the battery is judged to meet the preset charging conditions based on the battery parameters, it is considered that the battery needs to be recharged. However, when the network management message sent by the intelligent charging system is not received within a period of time, that is, the onboard controller has not received the charging request sent by the intelligent charging system within the preset time, it can be considered that the intelligent charging system is abnormal and cannot send a charging request to the onboard controller. The onboard controller wakes up the power battery system, completes the high-voltage power-on, and then outputs the charging voltage required by the battery through the DCDC conversion module to recharge the battery. Therefore, when the intelligent charging system fails abnormally, the onboard controller can control the power battery system to recharge the battery, thereby realizing redundant charging control and reducing the risk of battery feeding.

[0047] It should be noted that the DCDC conversion module can be integrated in the power battery system or can be a separate voltage conversion module, which is not limited here. In addition, the battery is a low-voltage battery in the vehicle, and its charging voltage is generally 12V / 24V.

[0048] In some embodiments, the battery parameters include power value and / or voltage value, and the preset charging condition includes: the battery power value is less than a preset power threshold; and / or the battery voltage value is less than a preset voltage threshold. The preset power threshold and the preset voltage threshold can be calibrated and adjusted according to actual conditions.

[0049] That is to say, whether the battery needs to be recharged is determined according to the battery power value, wherein when the battery power value is less than the preset power threshold, it is considered that the battery needs to be recharged; when the battery power value is greater than or equal to the preset power threshold, it is considered that the battery does not need to be recharged. It is also possible to determine whether the battery needs to be recharged according to the battery voltage value, wherein when the battery voltage value is less than the preset voltage threshold (recharge voltage), it is considered that the battery needs to be recharged; when the battery voltage value is greater than or equal to the preset voltage threshold, it is considered that the battery does not need to be recharged. It is also possible to determine whether the battery needs to be recharged according to the battery power value and voltage value, wherein when the battery power value is less than the preset power threshold and the battery voltage value is less than the preset voltage threshold, it is considered that the battery needs to be recharged; when the battery power value is greater than or equal to the preset power threshold and the battery voltage value is greater than or equal to the preset voltage threshold, it is considered that the battery does not need to be recharged. Thus, it is possible to determine whether the battery meets the preset recharge conditions according to a variety of parameters, thereby improving the accuracy of the judgment result.

[0050] In some embodiments, the above-mentioned vehicle power replenishment control method also includes: when it is determined according to the parameters of the battery that the preset power replenishment conditions are not met, determining the wake-up interval of the vehicle controller according to the parameters of the battery, and controlling the vehicle controller to enter a sleep state; wherein, the larger the parameters of the battery, the longer the wake-up time interval, and the smaller the parameters of the battery, the shorter the wake-up time interval.

[0051] Specifically, in the event of an abnormal failure of the intelligent charging system, it is determined whether the preset charging conditions are met based on the parameters of the battery. When it is determined that the preset charging conditions are not met based on the parameters of the battery (voltage value and / or power value), it is considered that the battery has sufficient power to meet the needs of the vehicle. At this time, there is no need to control the power battery system to charge the battery, and the on-board controller is controlled to enter a dormant state to reduce the energy loss of the on-board controller. At the same time, the wake-up time interval of the on-board controller is dynamically adjusted according to the parameters of the battery, that is, the time for the next wake-up of the on-board controller is adjusted. The larger the battery parameters, the longer the wake-up time interval, and the smaller the battery parameters, the shorter the wake-up time interval. By dynamically adjusting the wake-up time interval, the loss of power can be reduced.

[0052] For example, when the battery parameter includes the power value, when the power value of the battery is larger, it indicates that the available time of the battery is longer, and the wake-up time interval can be increased; when the power value of the battery is smaller, it indicates that the available time of the battery is shorter, and the wake-up time interval can be shortened. For example, when the battery power is 50%, the wake-up time interval of the vehicle controller is shorter than the wake-up time interval of the vehicle controller when the battery power is 70%.

[0053] It should be noted that when the battery parameter includes a voltage value, its logic is the same as that of the power value, which will not be described here. In addition, when the vehicle is stationary, the onboard controller needs to be awakened, and when the vehicle is in motion, the onboard controller is always awakened.

[0054] In some embodiments, the above-mentioned vehicle charging control method further includes: when the intelligent charging system is not faulty, if the battery parameters meet the preset charging conditions, receiving a charging request issued by the intelligent charging system; and controlling the power battery system to charge the battery according to the charging request.

[0055] That is to say, when the intelligent charging system wakes up by itself, or wakes up at a fixed time interval, or when the wake-up time interval determined by the parameters of the battery detected last time is reached, it is determined based on the parameters of the battery that the battery needs to be recharged. At this time, the intelligent charging system will send a charging request to the vehicle controller, and the charging request will carry the battery's power value and / or voltage value, charging voltage, charging rate, charging time, etc. When the vehicle controller receives the charging request from the intelligent charging system, it will wake up the power battery system, complete the high-voltage power-on instruction, and output the charging voltage required by the battery to recharge the battery. In this way, when the intelligent charging system is working normally, the intelligent charging system can send a charging request without excessive involvement of the vehicle controller, thereby improving the operating rate of the vehicle controller.

[0056] It should be noted that regardless of whether the vehicle is in a driving state or a stopped state, the intelligent charging system needs to be awakened. When the battery does not need to be charged, the intelligent charging system is in a dormant state, which can reduce energy consumption.

[0057] In some embodiments, the above-mentioned vehicle charging control method further includes: when the battery parameters do not meet the preset charging conditions, controlling the intelligent charging system to enter a dormant state.

[0058] That is to say, when there is no abnormal failure in the intelligent charging system, it is determined based on the battery parameters that the battery does not meet the preset charging conditions, which means that the battery can meet the needs of the vehicle and no charging is required. At this time, the intelligent charging system is controlled to enter a sleep state, thereby reducing the energy consumption of the intelligent charging system.

[0059] In some embodiments, the parameters of the battery include the charging voltage, and the vehicle's power battery system is controlled to replenish the battery according to the battery parameters, including: determining the target output voltage of the power battery system according to the charging voltage to replenish the battery, thereby adapting the charging voltage of the battery, increasing the service life of the battery, and improving the stability of the battery output current.

[0060] In some embodiments, when the battery power value is greater than a certain power level or is fully charged, or when the battery charging time reaches a set time, the battery charging is stopped to avoid overcharging the battery and reducing the battery service life.

[0061] As a specific example, Figure 2 As shown, the intelligent charging system is connected to the battery (low-voltage battery) through a low-voltage signal line, the on-board controller is connected to the intelligent charging system, the power battery system and the DCDC converter through the CAN signal line, and is connected to the battery at a low voltage. The power battery system is connected to the DCDC converter through a high-voltage signal line, and the DCDC converter is connected to the battery at a low voltage. The intelligent charging system collects the parameters of the battery, and when it determines that the battery needs to be charged based on the parameters of the battery, it sends a charging request to the on-board controller. After receiving the charging request, the on-board controller wakes up the power battery system and the DCDC converter, completes the high-voltage power-on, and instructs the DCDC converter to output the charging voltage requested for charging the battery. When the intelligent charging system determines that the battery does not need to be charged based on the parameters of the battery, it does not need to send a charging request to the on-board controller and enters a dormant state.

[0062] In the event of an abnormal failure of the intelligent charging system, the on-board controller determines that the battery needs to be charged based on the battery parameters, wakes up the power battery system and DCDC converter, completes high-voltage power-up, and instructs the DCDC converter to output the charging voltage requested for charging to charge the battery. When the on-board controller determines that the battery does not need to be charged based on the battery parameters, it enters a dormant state.

[0063] Combine the following Figure 3 Describe the power supply control method of the intelligent power supply system of the present application when it is working normally, such as Figure 3 As shown, the intelligent charging system wakes up automatically when the vehicle is in a dormant state, wherein the self-wake-up method includes one of scheduled wake-up, triggered wake-up, and the current wake-up time determined according to the battery power level at the last wake-up. Then, it is identified whether the battery power level is lower than the set threshold, wherein if the battery power level is lower than the set threshold, the intelligent charging system sends a network management message to the on-board controller to wake up the on-board controller and send a charging request at the same time. After receiving the intelligent charging request, the on-board controller wakes up the power battery system and the DCDC converter, completes the high-voltage power-on, and controls the DCDC converter to output the charging voltage requested for charging. At this time, the DCDC is enabled and starts to charge the battery. After the intelligent charging system wakes up, if the battery power level is higher than the set threshold, the intelligent charging system is controlled to enter a dormant state.

[0064] Combine the following Figure 4 Describe the control method of the vehicle controller for charging control when the intelligent charging system of the present application works abnormally, such as Figure 4 As shown, when the intelligent power replenishment system fails, the on-board controller wakes itself up, and the wake-up method may include one of scheduled wake-up and determination based on the battery charge value at the last wake-up. The on-board controller monitors the battery charge value, and when the battery charge value is lower than the set value, wakes up the power battery system and the DCDC converter to complete the high-voltage power-on, and at the same time controls the DCDC converter to output the set voltage (battery charging voltage) to replenish the battery. After the on-board controller wakes up, if the battery charge value is higher than the set value, the on-board controller enters a dormant state. In addition, after each wake-up of the on-board controller, the time interval for waking up the on-board controller next time is dynamically adjusted according to the battery charge value. When the battery charge value is higher, the wake-up time interval of the on-board controller is set to be longer; when the battery charge value is lower, the wake-up time interval of the on-board controller is set to be shorter. When there is no failure in the intelligent power replenishment system, follow Figure 3 The process shown is to control the battery charging.

[0065] In summary, in the technical solution of the embodiment of the present application, when the vehicle-mounted controller of the vehicle is in the awake state, the parameters of the battery are obtained, wherein the parameters of the battery may include the voltage value of the battery, the power of the battery, etc. When the battery is judged to meet the preset charging conditions according to the parameters of the battery, it is considered that the battery needs to be charged. When the charging request of the intelligent charging system is not received within a period of time, it is considered that the intelligent charging system is abnormal and cannot send a charging request to the vehicle-mounted controller. At this time, the vehicle-mounted controller directly controls the power battery system to charge the battery. Therefore, when the intelligent charging system fails abnormally, the vehicle-mounted controller can control the power battery system to charge the battery, thereby realizing redundant charging control and reducing the risk of battery feeding.

[0066] Corresponding to the above-mentioned embodiment, the present application also proposes a vehicle power replenishment control device.

[0067] like Figure 5 As shown, the vehicle charging control device 100 of the present application may include: an acquisition module 110, which is used to acquire the parameters of the battery when the vehicle-mounted controller of the vehicle is in an awake state; a determination module 120, which is used to determine that the intelligent charging system has a fault when it is determined according to the parameters of the battery that the preset charging conditions are met and no charging request from the vehicle's intelligent charging system is received; and a control module 130, which is used to control the vehicle's power battery system to charge the battery according to the battery parameters when the intelligent charging system has a fault.

[0068] Specifically, the vehicle's on-board controller is in an automatic wake-up state when a certain period of time is reached. The smart charging system can be awakened according to the acquired time interval or by hardware triggering. The hardware triggering method can be to output a high-level signal when the battery voltage is less than the charging voltage value to put the smart charging system in an awake state.

[0069] When the vehicle's onboard controller is in the awake state, the acquisition module 110 acquires the parameters of the battery, where the battery parameters may include the battery voltage value, the battery power, etc. When the determination module 120 determines that the battery meets the preset charging conditions based on the battery parameters, it is considered that the battery needs to be recharged. However, when the network management message sent by the intelligent charging system is not received within a period of time, that is, the onboard controller does not receive the charging request sent by the intelligent charging system within the preset time, it can be considered that the intelligent charging system is abnormal and cannot send a charging request to the onboard controller. The control module 130 controls the onboard controller to wake up the power battery system, complete the high-voltage power-on, and then output the charging voltage required by the battery through the DCDC conversion module to recharge the battery. Therefore, when the intelligent charging system fails abnormally, the onboard controller can control the power battery system to recharge the battery, thereby realizing redundant charging control and reducing the risk of battery feeding.

[0070] In some embodiments, the battery parameters include power value and / or voltage value, and the preset charging condition includes: the battery power value is less than a preset power threshold; and / or the battery voltage value is less than a preset voltage threshold. The preset power threshold and the preset voltage threshold can be calibrated and adjusted according to actual conditions.

[0071] That is to say, the determination module 120 determines whether the battery needs to be recharged according to the battery power value, wherein when the battery power value is less than the preset power threshold, it is considered that the battery needs to be recharged; when the battery power value is greater than or equal to the preset power threshold, it is considered that the battery does not need to be recharged. It is also possible to determine whether the battery needs to be recharged according to the battery voltage value, wherein when the battery voltage value is less than the preset voltage threshold (recharge voltage), it is considered that the battery needs to be recharged; when the battery voltage value is greater than or equal to the preset voltage threshold, it is considered that the battery does not need to be recharged. It is also possible to determine whether the battery needs to be recharged according to the battery power value and voltage value, wherein when the battery power value is less than the preset power threshold and the battery voltage value is less than the preset voltage threshold, it is considered that the battery needs to be recharged; when the battery power value is greater than or equal to the preset power threshold and the battery voltage value is greater than or equal to the preset voltage threshold, it is considered that the battery does not need to be recharged. Thus, it is possible to determine whether the battery meets the preset recharge conditions according to a variety of parameters, thereby improving the accuracy of the judgment result.

[0072] In some embodiments, the determination module 120 is also used to determine the wake-up interval of the vehicle controller according to the parameters of the battery when it is determined that the preset charging conditions are not met according to the parameters of the battery; wherein, the larger the parameters of the battery, the longer the wake-up time interval, and the smaller the parameters of the battery, the shorter the wake-up time interval; the control module 130 is also used to control the vehicle controller to enter a sleep state.

[0073] Specifically, when the intelligent charging system fails abnormally, the determination module 120 determines whether the preset charging conditions are met based on the parameters of the battery. When the determination module 120 determines that the preset charging conditions are not met based on the parameters of the battery (voltage value and / or power value), it is considered that the battery has sufficient power to meet the needs of the vehicle. At this time, there is no need to control the power battery system to charge the battery. The control module 130 controls the vehicle controller to enter a sleep state to reduce the energy loss of the vehicle controller. At the same time, the control module 130 also dynamically adjusts the wake-up time interval of the vehicle controller according to the parameters of the battery, that is, adjusts the time for the next wake-up of the vehicle controller. The larger the battery parameters, the longer the wake-up time interval, and the smaller the battery parameters, the shorter the wake-up time interval. By dynamically adjusting the wake-up time interval, the loss of power can be reduced.

[0074] For example, when the battery parameter includes the power value, when the power value of the battery is larger, it indicates that the available time of the battery is longer, and the wake-up time interval can be increased; when the power value of the battery is smaller, it indicates that the available time of the battery is shorter, and the wake-up time interval can be shortened. For example, when the battery power is 50%, the wake-up time interval of the vehicle controller is shorter than the wake-up time interval of the vehicle controller when the battery power is 70%.

[0075] In some embodiments, the control module 130 is also used to receive a charging request from the intelligent charging system and control the power battery system to charge the battery according to the charging request if the battery parameters meet the preset charging conditions when the intelligent charging system is not faulty.

[0076] That is to say, when the intelligent charging system wakes up by itself, or wakes up at a fixed time interval, or when the wake-up time interval determined by the parameters of the battery detected last time is reached, the determination module 120 determines that the battery needs to be recharged based on the parameters of the battery. At this time, the intelligent charging system will send a recharge request to the vehicle controller, and the recharge request will carry the battery power value and / or voltage value, charging voltage, charging rate, charging time, etc. When the vehicle controller receives the recharge request from the intelligent charging system, the control module 130 controls the vehicle controller to wake up the power battery system, complete the high-voltage power-on instruction, and output the charging voltage required by the battery to recharge the battery. In this way, when the intelligent charging system is working normally, the intelligent charging system can send a recharge request without excessive involvement of the vehicle controller, thereby improving the operating rate of the vehicle controller.

[0077] In some embodiments, the control module is further used to control the intelligent charging system to enter a dormant state when the battery parameters do not meet the preset charging conditions.

[0078] That is to say, when there is no abnormal failure in the intelligent charging system, the determination module 120 determines that the battery does not meet the preset charging conditions based on the battery parameters, indicating that the battery can meet the needs of the vehicle and no charging is required. At this time, the control module 130 controls the intelligent charging system to enter a sleep state, thereby reducing the energy consumption of the intelligent charging system.

[0079] In some embodiments, the parameters of the battery include the charging voltage, and the control module is also used to determine the target output voltage of the power battery system based on the charging voltage to replenish the battery, thereby adapting the charging voltage of the battery, increasing the service life of the battery, and improving the stability of the battery output current.

[0080] In some embodiments, when the battery power value is greater than a certain power level or is fully charged, or when the battery charging time reaches a set time, the battery charging is stopped to avoid overcharging the battery and reducing the battery service life.

[0081] It should be noted that for details not disclosed in the vehicle power replenishment control device of the embodiment of the present application, please refer to the details disclosed in the vehicle power replenishment control method of the embodiment of the present application, and the details will not be repeated here.

[0082] In summary, when the vehicle's onboard controller is in the awake state, the acquisition module acquires the battery parameters, where the battery parameters may include the battery voltage value, the battery power, etc. When the determination module determines that the battery meets the preset charging conditions based on the battery parameters, it is considered that the battery needs to be charged. When the charging request of the intelligent charging system is not received within a period of time, it is considered that the intelligent charging system is abnormal and cannot send a charging request to the onboard controller. At this time, the control module controls the onboard controller to control the power battery system to charge the battery. Therefore, when the intelligent charging system fails abnormally, the onboard controller can control the power battery system to charge the battery, thereby realizing redundant charging control and reducing the risk of battery feeding.
