The invention discloses a storage battery power shortage prevention control method, system and device and a storage medium, and the method comprises the steps: when an electric vehicle enters a static state after a key is closed, a VCU, a BMS and a DCDC respectively enter a dormant state; after the VCU enters the dormant state, regularly waking up the VCU, and judging whether a storage battery is about to enter a power-lack state or not after waking up the VCU; and when the VCU judges that the storage battery is about to enter the power shortage state, the BMS and the DCDC are awakened, so that the BMS and the DCDC are utilized to charge the storage battery.

    本发明公开了一种蓄电池防亏电控制方法、系统、设备及存储介质,其方法包括:当电动车辆关钥匙进入静止状态时,VCU、BMS以及DCDC分别进入休眠状态;在所述VCU进入休眠状态之后进行定期唤醒,并在唤醒后判断蓄电池是否即将进入亏电状态;当所述VCU判断蓄电池即将进入亏电状态时,对所述BMS和所述DCDC进行唤醒,以便利用所述BMS和所述DCDC为所述蓄电池进行补电。
