The invention provides a vehicle storage battery charging method, device and equipment and a vehicle. A charging gun is determined to be connected, and the voltage of a vehicle storage battery is obtained; in response to the fact that the voltage of the storage battery is smaller than the vehicle starting voltage, a charging control system is awakened and controlled to enter a rescue mode, and the rescue mode is a mode that the storage battery is powered through the charging control system, and a vehicle battery management system is forbidden to be powered on; and charging the storage battery in the rescue mode. According to the rescue mode, power is supplied to the storage battery through the charging control system so that the vehicle can be successfully started subsequently, a user does not need to use another battery for rescue power connection, and the problem that the vehicle is damaged due to reverse power connection is solved. Meanwhile, the vehicle battery management system is forbidden to be powered on in the rescue mode, and the situation that the vehicle still cannot be started due to the fact that the battery management system is powered on and the storage battery is distributed to other modules of the vehicle is avoided.

    本公开提供了一种车辆蓄电池充电方法、装置、设备及车辆,确定连接充电枪,获取车辆蓄电池电压;响应于所述蓄电池电压小于车辆启动电压,唤醒充电控制系统,并控制充电控制系统进入救援模式,其中所述救援模式为通过充电控制系统为蓄电池供电,且禁止车辆电池管理系统上电的模式;在所述救援模式下为所述蓄电池充电。所述救援模式为通过充电控制系统为蓄电池供电,以供后续实现车辆成功启动,无需用户使用另一块电池进行救援搭电,避免搭电反接造成车辆损坏的问题。同时,救援模式下禁止车辆电池管理系统上电,避免因电池管理系统上电,使得蓄电池电量分配至车辆其他模块,导致车辆仍然无法启动。
