The invention discloses a method, a device and equipment for correcting the state of charge of a vehicle battery, and a storage medium. The method comprises the following steps: acquiring the number of vehicle charging and discharging cycles accumulated from the last SOC correction to the current time period of the vehicle battery; in response to the fact that the vehicle charge-discharge cycle number is larger than a cycle number threshold value, the actual voltage of a vehicle battery is obtained; and in response to the fact that the actual voltage is smaller than the full-charge cut-off voltage, starting an engine and a generator to charge a vehicle battery, and ending charging until the actual voltage of the vehicle battery reaches the full-charge cut-off voltage. According to the method, under the state of not depending on external equipment, when the vehicle charging and discharging cycle index is larger than the cycle index threshold value and the actual voltage of the vehicle battery is smaller than the full-charge cutoff voltage, the transmitter and the generator are started to charge the vehicle battery, the battery voltage leaves the platform area, and full-charge correction is completed; and the whole vehicle anchoring risk caused by the SOC deviation of the battery is effectively reduced.

    本发明公开了一种车辆电池的荷电状态修正方法、装置、设备及存储介质,方法包括:获取车辆电池从上次进行SOC修正到当前时间段内累计的车辆充放电循环次数;响应于所述车辆充放电循环次数大于循环次数阈值,获取车辆电池的实际电压;响应于所述实际电压小于满充截至电压,启动发动机和发电机,对车辆电池进行充电,直至车辆电池的实际电压达到所述满充截至电压,结束充电。该方法可以在不依赖外部设备的状态下,在车辆充放电循环次数大于循环次数阈值,且车辆电池的实际电压小于满充截至电压时,启动发送机和发电机对车辆电池进行充电,让电池电压离开平台区完成满充修正,有效降低电池SOC偏差带来的整车抛锚风险。
