One or more embodiments of the invention provide an electric quantity management method and device for a battery pack. The method comprises the following steps: acquiring a first endurance mileage which is set by a user and needs to be reserved when a battery pack of a vehicle supplies power to an external power grid; and based on the first endurance mileage, calculating to obtain a target SOC required to be reserved by the battery pack, so as to stop the battery pack from supplying power to an external power grid when the residual electric quantity of the battery pack reaches the target SOC. Therefore, after discharging of the battery pack is finished, the battery pack can still meet the vehicle using requirement of a user.

    本说明书一个或多个实施例提供一种电池包的电量管理方法及装置。该方法包括:获取用户设定的在车辆的电池包对外部电网进行供电时所需要保留的第一续航里程;基于所述第一续航里程,计算得到所述电池包所需要保留的目标SOC,以在所述电池包的剩余电量达到所述目标SOC时,停止电池包对外部电网进行供电。据此,可以使电池包在结束放电后,仍能够满足用户的用车需求。
