    • A system for balancing charge within a battery pack with a plurality of cells connected in series, including a capacitor; a processor configured to select a combination of donor cells and receiver cells from the plurality of cells in one of the following two modes: (1) a first mode where the number of donor cells is equal to the number of receiver cells, and (2) a second mode where the number of donor cells is greater than the number of receiver cells; and a plurality of switches that electrically connect the capacitor to the donor cells to charge the capacitor, and that electrically connected the capacitor to the receiver cells to discharge the capacitor. The transfer of charge between cells in the plurality of cells through the capacitor balances the charge within the battery pack.
    • 一种用于平衡电池组中的电荷的系统,其中多个单元串联连接,包括电容器; 处理器,其被配置为以下述两种模式之一从所述多个单元中选择供体单元和接收器单元的组合:(1)第一模式,其中供体单元的数量等于接收器单元的数量,以及(2 )第二模式,其中供体细胞的数量大于接收器细胞的数量; 以及多个开关,其将所述电容器电连接到所述施主单元以对所述电容器充电,并且将所述电容器电连接到所述接收器单元以对所述电容器进行放电。 通过电容器在多个电池中的电池之间的电荷转移平衡了电池组内的电荷。
