A battery pack includes a voltage bus, a first subset, and a second subset. The second subset includes a plurality of modules. The battery pack may be configured in a first configuration in which the first subset and the second subset are connected in parallel across the bus and the modules are connected in series within the second subset. The battery pack may also be configured in a second configuration in which the first subset and the second subset are connected in series across the bus and the modules are connected in parallel within the second subset. The battery pack then switches between a first configuration and a second configuration when the voltage of the battery pack passes a first threshold.
一种电池组,其包括电压总线、第一子组和第二子组。第二子组包括多个模块。电池组可配置成第一配置,其中第一子组和第二子组跨总线并联连接并且模块在第二子组内串联连接。电池组还可配置成第二配置,其中第一子组和第二子组跨总线串联连接,并且模块在第二子组内并联连接。当电池组的电压经过第一阈值时,电池组然后在第一配置与第二配置之间切换。
