In one exemplary embodiment, a system in a vehicle includes two or more battery packs. Each of the two or more battery packs corresponds to a battery monitoring system (BMS) that monitors charge and voltage of the battery pack. The system also includes three or more switches coupled to the two or more battery packs and a vehicle controller that controls the three or more switches to operate in a plurality of modes. In one of the plurality of modes, the three or more switches are controlled by a vehicle controller to charge only one of the two or more battery packs with a charger external to the vehicle to equalize a voltage between the two or more battery packs.
在一个示例性实施例中,车辆中的系统包括两个或更多个电池组。所述两个或更多个电池组中的每一个对应于监测电池组的电荷和电压的电池监测系统(BMS)。该系统还包括耦合到两个或更多个电池组的三个或更多个开关和控制所述三个或更多个开关在多种模式下操作的车辆控制器。在多种模式之一中,所述三个或更多个开关由车辆控制器控制,以利用车辆外部的充电器对所述两个或更多个电池组中的仅一个进行充电,以均衡所述两个或更多个电池组之间的电压。
