The vehicle includes two or more battery packs configured to supply power to the motor. The controller is configured to dynamically activate an operating mode during operation. The operating mode is one of a plurality of possible operating modes including a first operating mode defining a series connection between two or more battery packs and a second operating mode defining a parallel connection between two or more battery packs. Connection between the battery packs is controlled by a first plurality of switches. The plurality of low voltage loads are connected to a subset of the battery packs such that power outputs of the subset of the battery packs provide full power to the plurality of low voltage loads. In both the first mode of operation and the second mode of operation, the plurality of low voltage loads are connected to only the subset of the battery packs.
车辆包括被配置为向马达供电的两个或更多个电池组。控制器被配置为在操作期间动态地激活操作模式。操作模式是多种可能的操作模式中的一种,所述多种可能的操作模式包括限定两个或更多个电池组之间的串联连接的第一操作模式和限定两个或更多个电池组之间的并联连接的第二操作模式。电池组之间的连接由第一多个开关控制。多个低电压负载连接到电池组中的电池组的子集,使得电池组的子集的功率输出向多个低电压负载提供全功率。在所述第一操作模式和所述第二操作模式两者中,所述多个低电压负载仅连接到所述电池组的所述子集。
