摘要： An object of the present invention is to provide a flexible-grouping current sharing method for a bus sharing charger system. By analyzing information of the charger system (including a power distribution unit (PDU) and a charging module), a charging control unit (CCU) automatically distributes a certain amount of PDU and charging modules for serving as a specific charging group to achieve charging operation to a charging object (battery). During the process, each of the charging modules in the groups automatically achieves within-group current sharing by data filtering, and out-group module is not involved in the current sharing. When the capacity or quantity of the charging objects (battery) changes, the system distributes one or more specific charging group again to achieve charging operation on different charging objects (battery) simultaneously or with time interval.
