A vehicle includes an electrical system for balancing a state of charge in a battery pack. An electrical system includes a plurality of module groups. The switch array includes a plurality of switches. Each switch is coupled to a respective group of modules. The switch may be in one of a first state in which the module group is connected to the first low voltage bus, a second state in which the module group is connected to the second low voltage bus, and a third state in which the module group is disconnected from both the first low voltage bus and the second low voltage bus. The array is placed in a first phase of an operational mode in which at least one switch is in one of a first state and a second state, and is cycled through the phase of the mode to balance charging between the plurality of module groups.
车辆包括用于平衡电池组中的充电状态的电气系统。电气系统包括多个模块组。开关阵列包括多个开关。每个开关耦合到相应的模块组。开关可以处于将模块组连接到第一低压总线的第一状态、将模块组连接到第二低压总线的第二状态以及模块组与第一低压总线和第二低压总线两者断开连接的第三状态中的其中一种状态。阵列被置于操作模式的第一阶段,其中至少一个开关处于第一状态和第二状态中的其中一个状态,并且通过所述模式的阶段循环以平衡多个模块组之间的充电。
