The invention relates to an electric vehicle storage battery charging method and device, a medium and a product, and relates to the technical field of electric vehicles. The method comprises the steps that when the electric vehicle is powered off and stands still, the voltage of a storage battery is monitored; judging whether the voltage of the storage battery is smaller than a threshold value or not; if the voltage of the storage battery is smaller than a threshold value, sending a charging instruction; calculating the to-be-charged time of the storage battery to obtain the to-be-charged time of the storage battery; and performing high-voltage charging on the storage battery by using a battery pack based on the charging instruction. The problem that ignition cannot be achieved due to the fact that the storage battery is lack of electricity when a user does not use the vehicle for a long time can be solved.

    本公开涉及一种电动汽车蓄电池补电方法、装置、介质及产品,涉及电动汽车技术领域。其中,该方法包括:在电动汽车下电静置时,对蓄电池的电压进行监控;判断所述蓄电池的电压是否小于阈值;如果所述蓄电池的电压是小于阈值,则发送补电指令;对所述蓄电池的拟补电时间进行计算,得到蓄电池拟补电时间;基于所述补电指令使用电池包对所述蓄电池进行上高压补电。本公开能避免用户在长时间不使用车辆时出现蓄电池亏电导致无法点火的问题。
