[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0027] The present application provides a method for controlling battery charging. Figure 1 , which shows a schematic diagram of the implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: BCM (body control module) 11, IBS (Intelligent Battery Management System) 12, micro switch 13, VCU (Vehicle Control Unit) 14 and EBS (Electronic Braking System) 15.

[0028] Optionally, IBS12 is used to obtain the SOC, voltage and working status of the battery and send them to BCM11; IBS12 can also send its own status indication feedback information to BCM11 for BCM11 to judge the working status of IBS. Micro switch 13 is used to obtain the opening and closing status of the front hood and send it to BCM11. VCN14 is used to receive the charging request and stop charging request sent by BCM11, and control the charging and discharging of the power battery according to the charging request and stop charging request.

[0029] Exemplarily, EBS15 is used to turn off the automatic wake-up function when at least one of the following conditions is met: the third detection result indicates that the number of times the battery charging is completed is greater than the first number threshold, or the fourth detection result indicates that the number of times the vehicle is in a state where charging is prohibited is greater than the second number threshold, so as to avoid the problem that the whole vehicle cannot sleep due to continuous triggering of charging requests. Among them, BCM11, IBS12, micro switch 13, VCN14 and EBS15 establish a communication connection through a wired or wireless network.

[0030] Based on the above Figure 1 In the implementation environment shown in the figure, the present application embodiment provides a control method for battery charging. Figure 2 As shown, taking the method applied to BCM as an example, the method includes steps 201 to 205.

[0031] In step 201 , the BCM obtains a first detection result, which indicates whether the battery of the vehicle needs to be recharged.

[0032] In one possible implementation, the first detection result indicates whether the vehicle's battery needs to be recharged, and the BCM obtains the first detection result, including: obtaining the battery's SOC (State of Charge) and the battery's voltage; in response to at least one of the battery's SOC being lower than a second SOC threshold and lasting for a first period of time, or the battery's voltage being lower than a voltage threshold and lasting for a second period of time, obtaining the first detection result indicating that the battery needs to be recharged.

[0033] Exemplarily, the BCM may obtain the SOC of the battery and the voltage of the battery through the IBS. After determining the SOC of the battery and the voltage of the battery, the SOC of the battery is compared with the second SOC threshold, and the voltage of the battery is compared with the voltage threshold. If the SOC of the battery is lower than the second SOC threshold, the duration of the SOC of the battery being lower than the second SOC threshold is counted; if the voltage of the battery is lower than the voltage threshold, the duration of the voltage of the battery being lower than the voltage threshold is counted.

[0034] Optionally, if at least one of the following conditions is met: the duration during which the battery's SOC is lower than the second SOC threshold is greater than or equal to the first duration, or the duration during which the battery's voltage is lower than the voltage threshold is greater than or equal to the second duration, the BCM obtains the first detection result indicating that the battery needs to be recharged. Exemplarily, the second SOC threshold, the voltage threshold, the first duration, and the second duration can be set based on experience.

[0035] In step 202 , in response to obtaining a first detection result indicating that the battery has a need for recharging, the BCM obtains a second detection result indicating whether the vehicle meets a recharging start condition.

[0036] In a possible implementation, if the first detection result is obtained indicating that the battery needs to be recharged, the BCM wakes up the vehicle network and obtains the second detection result, wherein the second detection result indicates whether the vehicle meets the conditions for starting recharge. Optionally, the BCM obtains the second detection result, including: obtaining the working state of the battery, the working state of the IBS, and the opening and closing state of the front hood, the working state of the battery includes the normal battery and the abnormal battery, the working state of the IBS includes the normal IBS and the abnormal IBS, and the opening and closing state of the front hood includes the front hood open and the front hood closed; in response to the working state of the battery being the normal battery, the working state of the IBS being the normal IBS, and the opening and closing state of the front hood being the front hood closed, obtaining the second detection result indicates that the vehicle meets the conditions for starting recharge.

[0037] Optionally, the BCM may obtain the working state of the battery through the IBS, wherein the working state of the battery includes the normal state of the battery and the abnormal state of the battery. The BCM may also determine the working state of the IBS by obtaining the state indication feedback information of the IBS, wherein the working state of the IBS includes the normal state of the IBS and the abnormal state of the IBS. The BCM may also obtain the opening and closing state of the front hood through a micro switch. Exemplarily, the micro switch is installed on the front hood, and the BCM may determine whether the front hood is closed by reading the state of the micro switch. For example, when the front switch is closed, it indicates that the front hood is closed; when the front switch is disconnected, it indicates that the front hood is open.

[0038] In one possible implementation, after determining the working status of the battery, the working status of the IBS, and the opening and closing status of the hood, if the working status of the battery is that the battery is normal, the working status of the IBS is that the IBS is normal, and the opening and closing status of the hood is that the hood is closed, the BCM obtains a second detection result indicating that the vehicle meets the conditions for starting recharging.

[0039] In step 203 , in response to obtaining the second detection result indicating that the vehicle meets the charging start condition, the BCM controls the power battery to charge the storage battery.

[0040] Exemplarily, if the second detection result obtained indicates that the vehicle meets the conditions for starting power replenishment, the BCM controls the power battery to replenish the storage battery, including: the BCM sends a first power replenishment request to the VCU, and after receiving the first power replenishment request, the VCU controls the power battery to discharge to the storage battery, thereby realizing power battery replenishment of the storage battery.

[0041] In one possible implementation, in response to obtaining a second detection result indicating that the vehicle does not meet the conditions for starting power replenishment, the BCM obtains a fourth detection result, and the fourth detection result indicates whether the vehicle is in a power replenishment prohibited state; in response to obtaining the fourth detection result indicating that the vehicle is not in a power replenishment prohibited state, the power battery is controlled to replenish the storage battery.

[0042] Optionally, the BCM obtains a fourth detection result, including: the BCM obtains the SOC of the power battery; in response to the SOC of the power battery being less than the first SOC threshold, obtaining the fourth detection result indicating that the vehicle is in a state where power replenishment is prohibited; in response to the SOC of the power battery being greater than or equal to the first SOC threshold, obtaining the fourth detection result indicating that the vehicle is not in a state where power replenishment is prohibited.

[0043] For example, the BCM can obtain the SOC of the power battery through the IBS, and then compare the SOC of the power battery with the first SOC threshold. In a possible implementation, if the SOC of the power battery is less than the first SOC threshold, the BCM obtains the fourth detection result indicating that the vehicle is in a state where charging is prohibited; if the SOC of the power battery is greater than or equal to the first SOC threshold, the BCM obtains the fourth detection result indicating that the vehicle is not in a state where charging is prohibited.

[0044] Optionally, if the fourth detection result obtained indicates that the vehicle is not in a state where power replenishment is prohibited, the BCM controls the power battery to replenish the storage battery, including: the BCM sends a second power replenishment request to the VCU, and after receiving the second power replenishment request, the VCU controls the power battery to discharge to the storage battery, thereby realizing power battery replenishment of the storage battery.

[0045] In step 204 , the BCM obtains a third detection result, which indicates whether the battery charging is completed.

[0046] In a possible implementation, after the power battery starts to recharge the storage battery, the BCM obtains a third detection result, wherein the third detection result indicates whether the recharging of the storage battery is completed. Optionally, the BCM obtains the third detection result, including: counting the duration of the power battery recharging the storage battery; in response to the duration of the power battery recharging the storage battery reaching a preset duration, or the SOC of the storage battery is greater than or equal to at least one of a third SOC threshold, obtaining the third detection result indicating that the recharging of the storage battery is completed, and the third SOC threshold is greater than the second SOC threshold.

[0047] Optionally, after the power battery starts to recharge the battery, the BCM counts the duration of the power battery recharging the battery and continuously monitors the SOC of the battery. The BCM then compares the duration of the power battery recharging the battery with the preset duration, and compares the SOC of the battery with a third SOC threshold. Exemplarily, if at least one of the duration of the power battery recharging the battery is greater than or equal to the preset duration, or the SOC of the battery is greater than or equal to the third SOC threshold, the BCM obtains a third detection result indicating that the recharging of the battery is completed. The third SOC threshold can be set based on experience, and the third SOC threshold must be greater than the second SOC threshold.

[0048] Exemplarily, during the process of the power battery replenishing the battery, the BCM obtains a fifth detection result, which is used to indicate whether a replenishment termination condition is triggered; in response to obtaining the fifth detection result indicating that the replenishment termination condition is triggered, the power battery is controlled to stop replenishing the battery.

[0049] In a possible implementation, obtaining the fifth detection result includes: obtaining the SOC of the power battery, the working state of the IBS, and the opening and closing state of the front hood, the working state of the IBS includes the IBS normal and the IBS abnormal, and the opening and closing state of the front hood includes the front hood opened and the front hood closed; in response to the SOC of the power battery being less than the first SOC, the working state of the IBS being the IBS abnormal, or the opening and closing state of the front hood being the front hood open, obtaining the fifth detection result indicates the condition for triggering the termination of the power replenishment.

[0050] Optionally, during the process of the power battery replenishing the battery, the BCM continuously monitors the SOC of the power battery, the working state of the IBS, and the opening and closing state of the front hood. If the SOC of the power battery is less than the first SOC, the working state of the IBS is the IBS abnormality, or the opening and closing state of the front hood is the front hood open, the BCM obtains a fifth detection result indicating a condition for triggering the termination of the replenishment.

[0051] Exemplarily, after obtaining the fifth detection result indicating the triggering condition for termination of power replenishment, the BCM controls the power battery to stop replenishing the storage battery, including: the BCM sends a first stop power replenishment request to the VCU, and after receiving the first stop power replenishment request, the VCU controls the power battery to stop discharging to the storage battery, controls the high voltage of the entire vehicle to power off and enter a sleep state.

[0052] In step 205 , in response to obtaining the third detection result indicating that the battery charging is completed, the BCM controls the power battery to stop charging the battery.

[0053] Exemplarily, if the third detection result indicates that the battery charging is completed, the BCM controls the power battery to stop charging the battery, including: the BCM sends a second stop charging request to the VCU, and after receiving the second stop charging request, the VCU controls the power battery to stop discharging to the battery, controls the high voltage of the entire vehicle to power off and enter a sleep state.

[0054] In one possible implementation, in response to obtaining at least one of a third detection result indicating that the number of times the battery has been recharged is greater than a first count threshold, or a fourth detection result indicating that the number of times the vehicle is in a state where recharging is prohibited is greater than a second count threshold, the BCM controls the EBS wake-up function to be turned off.

[0055] Exemplarily, after the power battery starts to recharge the storage battery, the number of times the third detection result indicating that the recharging of the storage battery is completed and the number of times the fourth detection result indicating that the vehicle is in a state where recharging is prohibited are counted. The number of times the third detection result indicating that the recharging of the storage battery is completed is compared with the first number threshold, and the number of times the fourth detection result indicating that the vehicle is in a state where recharging is prohibited is compared with the second number threshold.

[0056] Optionally, if the third detection result indicates that the number of times the battery charging is completed is greater than the first number threshold, or the fourth detection result indicates that the number of times the vehicle is in the charging prohibition state is greater than the second number threshold, at least one of the following is satisfied, the BCM controls the EBS wake-up function to be turned off. The first number threshold and the second number threshold can be set based on experience, for example, both the first number threshold and the second number threshold can be 3 times.

[0057] By controlling the EBS wake-up function to be turned off when at least one of the following conditions is met: the third detection result indicates that the number of times the battery has been recharged is greater than the first number threshold, or the fourth detection result indicates that the number of times the vehicle is in a state where recharging is prohibited is greater than the second number threshold, the problem of the vehicle being unable to sleep due to continuous triggering of recharging requests is avoided, thereby ensuring that the vehicle can enter sleep mode normally.

[0058] In summary, Figure 3 A control logic diagram of battery charging is provided as an example for illustration. Optionally, the execution subject can be BCM. Step 301, obtain the SOC of the battery and the voltage of the battery. Step 302, determine whether at least one of the following conditions is met: the duration of the battery SOC being lower than the second SOC threshold is greater than or equal to the first duration, or the duration of the battery voltage being lower than the voltage threshold is greater than or equal to the second duration. If at least one of the following conditions is met: the duration of the battery SOC being lower than the second SOC threshold is greater than or equal to the first duration, or the duration of the battery voltage being lower than the voltage threshold is greater than or equal to the second duration, proceed to step 303. If both the duration of the battery SOC being lower than the second SOC threshold is greater than or equal to the first duration, and the duration of the battery voltage being lower than the voltage threshold is greater than or equal to the second duration, are not met, return to step 302.

[0059] Step 303, wake up the vehicle network and detect the conditions for starting the power replenishment. Step 304, determine whether the vehicle meets the conditions for starting the power replenishment. If the vehicle meets the conditions for starting the power replenishment, proceed to step 305; if the vehicle does not meet the conditions for starting the power replenishment, proceed to step 306. Step 306, determine whether the vehicle is in a charging prohibited state. If the vehicle is in a charging prohibited state, proceed to step 307; if the vehicle is not in a charging prohibited state, proceed to step 305. Step 307, prohibit charging the battery. Step 305, BCM sends a first power replenishment request to VCU. Step 308, VCU controls the power battery to discharge to the battery.

[0060] Step 309, determine whether the vehicle triggers the charging termination condition. If the vehicle triggers the charging termination condition, proceed to step 311; if the vehicle does not trigger the charging termination condition, proceed to step 310. Step 311, stop charging the battery; Step 310, determine whether the vehicle has completed charging the battery. If the vehicle has completed charging the battery, proceed to step 312. Step 312, stop charging the battery.
