A battery balancing method for balancing a voltage of a battery pack on a busbar of a utility vehicle is disclosed. The method includes determining, by a control system, a state of charge of a first battery pack and a second battery pack of the utility vehicle; in response to the state of charge of the first battery pack being greater than the state of charge of the second battery pack by more than a first threshold amount, initiating, by the control system, converter battery balancing to discharge the first battery pack to the second battery pack through the DC-DC converter; and in response to the state of charge of the first battery pack being less than a first threshold amount higher than the state of charge of the second battery pack, initiating, by the control system, direct battery balancing to discharge the first battery pack to the second battery pack.
公开了一种用于在多用途车的母排上平衡电池包的电压的电池平衡方法。该方法包括:由控制系统确定多用途车的第一电池包和第二电池包的荷电状态;响应第一电池包的荷电状态比第二电池包的荷电状态高超过第一阈值量,由控制系统发起转换器电池平衡以通过DC‑DC转换器将第一电池包向第二电池包放电;以及响应于第一电池包的荷电状态比第二电池包的荷电状态高小于第一阈值量,由控制系统发起直接电池平衡以将第一电池包向第二电池包放电。
