[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The battery repair method provided in the embodiment of the present application can be applied to an application environment where the battery of a vehicle is repaired when the battery is low on power. The battery repair method provided in the embodiment of the present application can be executed by a computer device, which can be a controller in a vehicle.

[0053] In one embodiment, Figure 1 As shown, a battery repair method is provided, which is described by taking the method applied to a controller as an example, and specifically includes the following steps:

[0054] S101: If it is detected that the battery of the target vehicle is low on power, a battery repair inquiry message is output to the target user.

[0055] The target user is any user who uses the target vehicle. The repair inquiry information is information used to inquire the target user whether to repair the battery.

[0056] Optionally, the status of the battery can be monitored by a battery monitoring device installed in the target vehicle. If a battery low power event sent by the battery monitoring device is received, it can be determined that the battery of the target vehicle is detected to be low on power; further, according to preset rules, battery repair inquiry information is generated, and the generated repair inquiry information is sent to a display device in the target vehicle, such as a vehicle-mounted screen.

[0057] S102: When the feedback information of the received repair inquiry information is confirmation of repair, determining repair reference data of the battery according to the attribute information of the battery.

[0058] Among them, the attribute information of the battery is information that characterizes the inherent attributes and performance of the battery. In the embodiment of the present application, the attribute information of the battery includes but is not limited to battery capacity, discharge current, voltage, operating temperature, etc. The repair reference data is the parameters required in the process of repairing the battery. In the embodiment of the present application, the repair reference data includes but is not limited to voltage step size, current lower limit value, current upper limit value and voltage upper limit value.

[0059] Optionally, when the feedback information of the received repair inquiry information is confirmation of repair, the repair reference data in the process of repairing the battery can be determined according to the attribute information of the battery, such as battery capacity, discharge current, voltage, operating temperature, etc. Exemplarily, the voltage upper limit value in the repair reference data can be determined according to the voltage in the attribute information, and the voltage step size, current lower limit value and current upper limit value can be determined according to the battery capacity.

[0060] S103, controlling the DC conversion power supply in the target vehicle to repair the battery according to the repair reference data and the actual state information of the battery.

[0061] Among them, the actual status information of the battery is the status information of the battery during the charging process; in this embodiment of the application, the actual status information includes but is not limited to the real-time current value of the battery.

[0062] Optionally, in the embodiment of the present application, the battery repair process is a process of adjusting the battery charging current. Therefore, the battery charging current can be adjusted by controlling the DC conversion power supply in the target vehicle according to the repair reference data and the actual state information of the battery during the repair process to achieve the battery repair process.

[0063] In the above-mentioned battery repair method, if it is detected that the battery of the target vehicle is low on power, a repair inquiry information for the battery is output to the target user; when the feedback information of the received repair inquiry information is to confirm the repair, the repair reference data of the battery is determined according to the attribute information of the battery; according to the repair reference data and the actual state information of the battery, the DC conversion power supply in the target vehicle is controlled to repair the battery. In the above-mentioned scheme, when the battery of the target vehicle is low on power, the battery of the target vehicle is repaired without affecting the use of the vehicle based on the feedback information of the repair inquiry information of the target user, thereby improving the use experience of the target user and the safety of the target vehicle during use; at the same time, according to the attribute information of the battery, the accuracy of the determined repair reference data of the battery is guaranteed; further, according to the repair reference data and the actual state information of the battery, the DC conversion power supply in the target vehicle is controlled to repair the battery, thereby ensuring the safety and effectiveness of the repair process, and realizing that the battery can be repaired without disassembling the battery.

[0064] Optionally, since the target vehicle will automatically lose power after a power failure, the battery monitoring device will not be able to continue working due to the vehicle power failure, and therefore may not be able to accurately monitor the power failure of the target vehicle. Figure 2 As shown, a method for detecting a battery power failure of a target vehicle is provided, which specifically includes the following steps:

[0065] S201, when it is detected that the target vehicle changes from a power-off state to a power-on state, determining whether battery low power information is stored in a non-volatile storage unit of the target vehicle.

[0066] Among them, the battery low power information is generated when the gateway device in the target vehicle detects that the battery's charge state is 0.

[0067] Optionally, when the vehicle battery is low on power, the response is usually to start the vehicle through an external power source (such as using a forced start or other vehicle fire). After the vehicle is successfully powered up, the low-voltage power source is switched from the previously used external power source to a DC power supply. Before the external power source is connected, the vehicle is in a low-power state and cannot supply power to the entire vehicle. The battery sensor is reset and cannot record information. After the external power source is connected, the battery sensor is powered on and starts working. At this time, the voltage and current obtained are the states after the external power source is connected. Before self-learning is completed, the battery power cannot be accurately estimated, and it is impossible to know whether the battery is low on power.

[0068] Therefore, in an embodiment of the present application, a non-volatile storage unit is reserved in the controller. Before the vehicle runs out of power, the controller monitors the battery information by reading the battery sensor signal, and records the battery power loss information in the non-volatile storage unit after the battery power drops to 0 (the battery still has power, but the rated capacity has been discharged).

[0069] S202, if the non-volatile storage unit stores battery low power information, and it is determined that the battery state of charge has suddenly changed according to the battery state of charge change information, it is determined that the battery of the target vehicle is low in power.

[0070] Optionally, if the vehicle charges the low-voltage battery by applying high voltage before the vehicle is completely powered off, and the battery charge rises above 0, it is judged that the battery is not depleted, and the battery depletion record in the non-volatile storage unit of the controller is cleared; conversely, if the battery charge increases before the vehicle is powered on (generally manifested as a sudden change), it is judged that the vehicle is connected to an external low-voltage power supply. If a depletion event is recorded in the non-volatile storage unit, the event will be reported and the vehicle will be judged to be depleted.

[0071] In the embodiment of the present application, by introducing a non-volatile storage unit and fully considering the charge state change information of the battery, the problem of failure of reading and inability to identify historical power-loss events due to battery sensor reset after the battery is low on power is effectively solved, and the power-loss phenomenon of the battery of the target vehicle can be accurately detected.

[0072] Optionally, the repair reference data includes a voltage step size, a current lower limit value, a current upper limit value, and a voltage upper limit value; in one embodiment, Figure 3 As shown, a method for repairing a battery is provided, which specifically includes the following steps:

[0073] S301, determining a current initial voltage value of a current repair round according to a voltage step size, a current upper limit value, a voltage upper limit value, and the last actual state information and the last initial voltage value of a last repair round.

[0074] Among them, the voltage step is the battery voltage increased in each repair round; the current upper limit value is the upper limit value of the battery charging current; the voltage upper limit value is the upper limit value of the battery voltage during the charging process; and the previous initial voltage value is the battery voltage in the previous repair round.

[0075] Optionally, the voltage change of the battery during repair of the battery in the current repair round can be determined based on the current upper limit value, the previous actual state information of the previous repair round, and the previous initial voltage value, and the current initial voltage value of the current repair round can be determined based on the voltage change and the voltage upper limit value and according to the voltage step.

[0076] Optionally, in order to ensure the accuracy of the determined current initial voltage value, the current initial voltage value of the current repair round can also be determined based on the size relationship between the previous real-time current value and the current upper limit value, and the size relationship between the previous initial voltage value and the voltage upper limit value.

[0077] Specifically, if the last real-time current value is less than the current upper limit value, and the last initial voltage value is less than the voltage upper limit value, the sum of the last initial voltage value and the voltage step size is used as the current initial voltage value. In other words, if the last real-time current value does not reach the current upper limit value, and the last initial voltage value does not reach the voltage upper limit value, the voltage step size is continued to be accumulated on the last initial voltage value to be used as the current initial voltage value.

[0078] If the last real-time current value is equal to the current upper limit value, and the last initial voltage value is less than the voltage upper limit value, the last initial voltage value is used as the current initial voltage value. In other words, if the last real-time current value reaches the current upper limit value, and the last initial voltage value does not reach the voltage upper limit value, the current cannot increase at this time, so the last initial voltage value needs to be maintained, that is, the last initial voltage value is used as the current initial voltage value.

[0079] If the last real-time current value is less than the current upper limit value, and the last initial voltage value is equal to the voltage upper limit value, the voltage upper limit value is used as the current initial voltage value. In other words, if the last real-time current value does not reach the current upper limit value, and the last initial voltage value reaches the voltage upper limit value, the voltage cannot be increased at this time, so the voltage upper limit value needs to be used as the current initial voltage value.

[0080] S302, in the current repair round, controlling the DC converter to supply power to the battery at the current initial voltage value, and obtaining current actual state information of the battery.

[0081] The current actual state information includes the current real-time current value.

[0082] Optionally, in the current repair round, the DC converter is controlled to supply power to the battery at the current initial voltage value, and during the power supply process, the current actual state information of the battery is obtained through the monitoring device.

[0083] S303, determining whether the battery meets the repair completion condition according to the magnitude relationship between the current real-time current value and the current lower limit value, and the magnitude relationship between the current initial voltage value and the voltage upper limit value.

[0084] Optionally, if the current real-time current value is less than the current lower limit value, and the initial voltage value is equal to the voltage upper limit value, it can be determined that the battery meets the repair completion condition.

[0085] S304, ending the battery repair process.

[0086] S305, taking the current repair round as the previous repair round, and returning to execute S301.

[0087] The embodiment of the present application repairs the battery in different repair rounds, and repairs the battery in the current repair round according to the repair result of the previous repair round, thereby realizing staged repair of the battery, that is, ensuring the safety and effectiveness of the repair process according to the actual status information of the battery.

[0088] Figure 4 FIG. 2 is a flow chart of a battery repair method in another embodiment. Based on the above embodiment, this embodiment provides an optional example of a battery repair method. Figure 4 The specific implementation process is as follows:

[0089] S401: If it is detected that the battery of the target vehicle is low on power, a battery repair inquiry message is output to the target user.

[0090] Optionally, when it is detected that the target vehicle changes from a power-off state to a power-on state, it is determined whether battery low power information is stored in the non-volatile storage unit of the target vehicle; wherein the battery low power information is generated when the gateway device in the target vehicle monitors that the battery's state of charge is 0; if the battery low power information is stored in the non-volatile storage unit, and it is determined that the battery's state of charge has suddenly changed based on the battery's state of charge change information, then it is determined that the battery of the target vehicle has been detected to be low in power.

[0091] S402: When the feedback information of the received repair inquiry information is confirmation of repair, the voltage step length, the current lower limit value, the current upper limit value and the voltage upper limit value of the battery are determined according to the attribute information of the battery.

[0092] S403: Using the preset voltage value as the last initial voltage value, and using the preset current value as the last actual state information.

[0093] S404, determining a current initial voltage value of a current repair round according to the voltage step size, the current upper limit value, the voltage upper limit value, and the last actual state information and the last initial voltage value of the last repair round.

[0094] Optionally, if the previous real-time current value is less than the current upper limit value, and the previous initial voltage value is less than the voltage upper limit value, then the sum of the previous initial voltage value and the voltage step is used as the current initial voltage value; if the previous real-time current value is equal to the current upper limit value, and the previous initial voltage value is less than the voltage upper limit value, then the previous initial voltage value is used as the current initial voltage value; if the previous real-time current value is less than the current upper limit value, and the previous initial voltage value is equal to the voltage upper limit value, then the voltage upper limit value is used as the current initial voltage value.

[0095] S405, in the current repair round, controlling the DC converter to supply power to the battery with the current initial voltage value, and obtaining the current real-time current value of the battery.

[0096] S406, determine whether the battery meets the repair completion conditions based on the size relationship between the current real-time current value and the current lower limit value, and the size relationship between the current initial voltage value and the voltage upper limit value; if so, execute S407; if not, execute S408.

[0097] Optionally, if the current real-time current value is less than the current lower limit value, and the initial voltage value is equal to the voltage upper limit value, it is determined that the battery meets the repair completion condition.

[0098] S407, ending the battery repair process.
