[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] This application provides a control method for battery charging. Please refer to... Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: a BCM (body control module) 11, an IBS (Intelligent Battery Management System) 12, a microswitch 13, a VCU (Vehicle Control Unit) 14, and an EBS (Electronic Braking System) 15.

[0028] Optionally, IBS12 is used to acquire the battery's SOC, voltage, and operating status and send them to BCM11; IBS12 can also send its own status indication feedback information to BCM11 for BCM11 to determine the operating status of IBS. Microswitch 13 is used to acquire the opening and closing status of the hood and send it to BCM11. VCN14 is used to receive charging requests and stop charging requests sent by BCM11, and control the charging and discharging of the power battery according to the charging and discharging requests.

[0029] For example, EBS15 is used to disable the automatic wake-up function when at least one of the following conditions is met: the number of times the third detection result indicates that the battery has been recharged is greater than the first threshold; or the number of times the fourth detection result indicates that the vehicle is in a state where recharging is prohibited is greater than the second threshold. This prevents the vehicle from falling asleep due to continuous recharging requests. BCM11, IBS12, microswitch 13, VCN14, and EBS15 establish a communication connection via a wired or wireless network.

[0030] Based on the above Figure 1 The implementation environment shown in this application provides a control method for battery charging, such as... Figure 2 As shown, taking the application of this method to BCM as an example, the method includes steps 201-205.

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

[0032] In one possible implementation, the first detection result indicates whether the vehicle's battery needs recharging. The BCM acquires the first detection result, including: acquiring the battery's SOC (State of Charge) and battery voltage; in response to at least one of the following: the battery's SOC is lower than a second SOC threshold for a first duration, or the battery voltage is lower than a voltage threshold for a second duration, the first detection result indicating that the battery needs recharging is acquired.

[0033] For example, the BCM can obtain the battery's SOC and voltage via IBS. After determining the battery's SOC and voltage, the battery's SOC is compared with a second SOC threshold, and the battery's voltage is compared with a voltage threshold. If the battery's SOC is lower than the second SOC threshold, the duration for which the battery's SOC is lower than the second SOC threshold is recorded; if the battery's voltage is lower than the voltage threshold, the duration for which the battery's voltage is lower than the voltage threshold is recorded.

[0034] Optionally, if at least one of the following conditions is met: the battery's SOC is below a second SOC threshold for a duration greater than or equal to a first duration, or the battery's voltage is below a voltage threshold for a duration greater than or equal to a second duration, the BCM obtains a first detection result indicating that the battery needs recharging. For example, the second SOC threshold, voltage threshold, first duration, and second duration can be set empirically.

[0035] In step 202, in response to the first detection result indicating that the battery needs to be recharged, the BCM obtains a second detection result, which indicates whether the vehicle meets the conditions for starting recharge.

[0036] In one possible implementation, if a first detection result indicates that the battery needs recharging, the BCM wakes up the vehicle network and obtains a second detection result, wherein the second detection result indicates whether the vehicle meets the conditions for starting recharging. Optionally, the BCM obtains the second detection result by: acquiring the battery's operating status, the IBS's operating status, and the hood's open / closed status. The battery's operating status includes battery normal and battery abnormal; the IBS's operating status includes IBS normal and IBS abnormal; and the hood's open / closed status includes hood open and hood closed. In response to the battery's operating status being battery normal, the IBS's operating status being IBS normal, and the hood's open / closed status being hood closed, the second detection result indicates that the vehicle meets the conditions for starting recharging.

[0037] Optionally, the BCM can obtain the battery's operating status via the IBS, whereby the battery operating status includes normal and abnormal battery conditions. The BCM can also determine the IBS's operating status by obtaining IBS status indication feedback information, whereby the IBS operating status includes IBS normal and IBS abnormal conditions. The BCM can also obtain the hood's open / closed status via a microswitch. For example, the microswitch is installed on the hood, and the BCM can determine whether the hood is closed by reading the microswitch's status. For instance, when the current switch is closed, it indicates the hood is closed; when the current switch is open, it indicates the hood is open.

[0038] In one possible implementation, after determining the battery's operating status, the IBS's operating status, and the hood's open / closed status, if the battery's operating status is "battery normal," the IBS's operating status is "IBS normal," and the hood's open / closed status is "hood closed," the BCM obtains a second detection result indicating that the vehicle meets the conditions for starting charging.

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

[0040] For example, if the second detection result indicates that the vehicle meets the charging start conditions, the BCM controls the power battery to charge the storage battery, including: the BCM sending a first charging request to the VCU, and after receiving the first charging request, the VCU controlling the power battery to discharge to the storage battery, thereby realizing the charging of the storage battery by the power battery.

[0041] In one possible implementation, in response to the second detection result indicating that the vehicle does not meet the charging start condition, the BCM obtains a fourth detection result indicating whether the vehicle is in a state where charging is prohibited; in response to the fourth detection result indicating that the vehicle is not in a state where charging is prohibited, the BCM controls the power battery to charge the storage battery.

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

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

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

[0045] In step 204, the BCM obtains a third detection result, which indicates whether the battery has been recharged.

[0046] In one possible implementation, after the power battery begins charging the storage battery, the BCM acquires a third detection result, wherein the third detection result indicates whether the charging of the storage battery is complete. Optionally, the BCM acquires the third detection result by: counting the duration of the power battery charging the storage battery; and in response to at least one of the following: the duration of the power battery charging the storage battery reaches a preset duration, or the storage battery's SOC is greater than or equal to a third SOC threshold, acquiring a third detection result indicating that the charging of the storage battery is complete, wherein the third SOC threshold is greater than a second SOC threshold.

[0047] Optionally, after the power battery begins charging the storage battery, the BCM (Battery Management Center) tracks the duration of the power battery charging the storage battery and continuously monitors the storage battery's State of Charge (SOC). The BCM then compares the duration of the power battery charging the storage battery with a preset duration and compares the storage battery's SOC with a third SOC threshold. For example, if at least one of the following conditions is met: the duration of the power battery charging the storage battery is greater than or equal to the preset duration, or the storage battery's SOC is greater than or equal to the third SOC threshold, the BCM obtains a third detection result indicating that the battery charging is complete. The third SOC threshold can be set empirically and must be greater than a second SOC threshold.

[0048] For example, during the process of the power battery replenishing the storage battery, the BCM obtains a fifth detection result, which is used to indicate whether the 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 storage battery.

[0049] In one possible implementation, obtaining the fifth detection result includes: obtaining the SOC of the power battery, the operating status of the IBS, and the opening / closing status of the front hood, wherein the operating status of the IBS includes IBS normal and IBS abnormal, and the opening / closing status of the front hood includes front hood open and front hood closed; in response to at least one of the following: the SOC of the power battery is less than the first SOC, the operating status of the IBS is IBS abnormal, or the opening / closing status of the front hood is front hood open, the fifth detection result is obtained to indicate the conditions for triggering the termination of the charging.

[0050] Optionally, during the process of the power battery replenishing the storage battery, the BCM continuously monitors the power battery's SOC, IBS operating status, and the opening / closing status of the hood. If the power battery's SOC is less than the first SOC, the IBS operating status is IBS abnormal, or the hood opening / closing status is at least one of the following, the BCM obtains a fifth detection result indicating the conditions for triggering the termination of the replenishment.

[0051] For example, after obtaining the fifth detection result indicating that the charging termination condition has been triggered, the BCM controls the power battery to stop charging the storage battery, including: the BCM sends a first stop charging request to the VCU, and after receiving the first stop charging request, the VCU controls the power battery to stop discharging to the storage battery, controls the vehicle to power down and enter a dormant state.

[0052] In step 205, in response to the third detection result indicating that the battery has been recharged, the BCM controls the power battery to stop recharging the battery.

[0053] For example, if the third detection result indicates that the battery has been recharged, the BCM controls the power battery to stop recharging the battery, including: the BCM sends a second stop recharging request to the VCU, and after receiving the second stop recharging request, the VCU controls the power battery to stop discharging to the battery, controls the vehicle to power down and enter a dormant state.

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

[0055] For example, after the power battery begins to charge the storage battery, the number of times the third detection result indicates that the battery charging is complete and the number of times the fourth detection result indicates that the vehicle is in a state where charging is prohibited are counted. The number of times the third detection result indicates that the battery charging is complete is compared with a first threshold, and the number of times the fourth detection result indicates that the vehicle is in a state where charging is prohibited is compared with a second threshold.

[0056] Optionally, if at least one of the following conditions is met: the number of times the third detection result indicates that the battery has been recharged is greater than the first threshold, or the number of times the fourth detection result indicates that the vehicle is in a state where recharging is prohibited is greater than the second threshold, the BCM controls the EBS wake-up function to be turned off. The first and second thresholds can be set empirically; for example, both the first and second thresholds can be set to 3 times.

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

[0058] In summary, with Figure 3 The following is an example of a control logic diagram for battery charging. Optionally, the execution entity can be a BCM. Step 301: Obtain the battery's SOC and voltage. Step 302: Determine whether at least one of the following conditions is met: the battery's SOC is lower than a second SOC threshold for a duration greater than or equal to a first duration, or the battery's voltage is lower than a voltage threshold for a duration greater than or equal to a second duration. If at least one of these conditions is met, proceed to step 303. If neither of these conditions is met, return to step 302.

[0059] Step 303: Wake up the vehicle network and check the charging start conditions. Step 304: Determine if the vehicle meets the charging start conditions. If the vehicle meets the charging start conditions, proceed to step 305; if the vehicle does not meet the charging start conditions, proceed to step 306. Step 306: Determine if 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: The BCM sends the first charging request to the VCU. Step 308: The VCU controls the power battery to discharge to the battery.

[0060] Step 309: Determine if the vehicle has triggered the battery charging termination condition. If the vehicle has triggered the battery charging termination condition, proceed to step 311; if the vehicle has not triggered the battery charging termination condition, proceed to step 310. Step 311: Stop charging the battery; Step 310: Determine if 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.

[0061] This embodiment of the application determines whether the battery needs recharging by obtaining a first detection result; when the first detection result indicates that the battery needs recharging, a second detection result is obtained to determine whether the vehicle meets the conditions for starting recharging; when the second detection result indicates that the vehicle meets the conditions for starting recharging, the power battery is controlled to recharge the battery, and a third detection result is obtained to determine whether the recharging is complete; when the third detection result indicates that the recharging of the battery is complete, the power battery is controlled to stop recharging the battery. This achieves control over the battery's recharging needs, avoids situations where the battery is depleted, ensures that recharging can be stopped in time when specific conditions are encountered during the recharging process, avoids ineffective recharging and safety hazards, and thus ensures the normal operation of battery recharging.
