The invention relates to a battery pack management system, a battery pack, a vehicle and a management method. A dynamic parallel operation management method for multiple battery packs is applied to a first battery pack and comprises the steps that a BMS monitors the states of the first battery pack and other battery packs, and the states of the first battery pack and the other battery packs comprise the disconnection state and the connection state; when the BMS judges that the difference value between the electric quantity of the first battery pack and the electric quantity of the other battery packs in the connection state is within a preset threshold range, the first battery pack is controlled to be switched from the disconnection state to the connection state based on the judgment, and the first battery pack is connected with the other battery packs in parallel. The connection state comprises a charging state and a discharging state, and the first battery pack is charged in the charging state and discharged in the discharging state.

    本申请涉及电池包管理系统、电池包、车辆及管理方法。一种多个电池包动态并机管理方法,应用于第一电池包,所述方法包括:所述BMS监测第一电池包和其它电池包的状态,所述第一电池包和其它电池包的状态包括断路状态和连接状态;所述BMS判断当所述第一电池包的电量和处于连接状态的其它电池包的电量差值处于预设阈值范围时,基于上述判断,控制所述第一电池包从所述断路状态切换至所述连接状态,所述第一电池包和所述其它电池包并联;其中,所述连接状态包括充电状态和放电状态,所述第一电池包在所述充电状态时被充电以及在所述放电状态时放电。
