The invention discloses a vehicle storage battery charging method and system, a vehicle and a storage medium, and the vehicle storage battery charging method is applied to the vehicle storage battery charging system and comprises the following steps: when it is detected that a high-voltage power supply of the vehicle is disconnected, obtaining a first current voltage value of a storage battery; determining target wake-up time corresponding to the first current voltage value; when the timing reaches the target wake-up time, generating a power supply demand; and controlling a high-voltage power supply of the vehicle to be connected based on the charging demand, and charging the storage battery. The technical problem that in the prior art, the feeding risk of a low-voltage storage battery is large is solved.

    本申请公开了一种车辆蓄电池补电方法、系统、车辆及存储介质,所述车辆蓄电池补电方法应用于车辆蓄电池补电系统,包括以下步骤:当检测到车辆的高压电源断开时,获取蓄电池的第一当前电压值;确定所述第一当前电压值对应的目标唤醒时间;在计时到达所述目标唤醒时间时,生成补电需求;基于所述补电需求控制车辆的高压电源连通,对所述蓄电池进行补电。本申请解决了现有技术低压蓄电池的馈电风险较大的技术问题。
