The present disclosure provides battery balancing based on cell capacity. A vehicle includes a traction battery and a controller. The controller is responsive to some of the battery cells of the traction battery reaching a first state of charge threshold. Other cells of the traction battery, each having a capacity greater than each of the some of the cells, are discharged to a second state of charge threshold greater than the first state of charge threshold without discharging the some of the cells. The controller then simultaneously charges all of the battery cells such that the some of the battery cells and the others of the battery cells simultaneously reach the same predetermined target state of charge.

    本公开提供“基于电池单元容量的电池组平衡”。一种车辆包括牵引电池和控制器。所述控制器响应于所述牵引电池的一些电池单元达到第一荷电状态阈值,在不使所述电池单元中的所述一些放电的情况下将每个都具有大于所述电池单元中的所述一些中的每个的容量的所述牵引电池的其它电池单元放电到大于所述第一荷电状态阈值的第二荷电状态阈值。所述控制器然后同时对全部所述电池单元充电,使得所述电池单元中的所述一些和所述电池单元中的所述其它同时达到相同的预定目标荷电状态。
