The invention relates to a balance control system and a balance control method for a vehicle battery module. A balance control system for a battery module includes a plurality of battery modules each including a battery outputting a battery voltage, a first DC/DC converter connected in parallel with the battery, and an inverter converting the battery voltage into an AC module voltage and outputting the AC module voltage, and a controller, the controller controls each of the plurality of battery modules. First DC/DC converters included in the plurality of battery modules are connected in parallel with each other, and the controller is configured to monitor a battery state including at least one of a state of charge of the battery or a battery voltage, and control the first DC/DC converters to an on state or an off state based on the battery state.

    本发明涉及用于车辆电池模块的平衡控制系统和平衡控制方法。用于电池模块的平衡控制系统包括多个电池模块和控制器,每个电池模块包括输出电池电压的电池、与电池并联连接的第一直流/直流转换器、以及将电池电压转换为交流模块电压并输出交流模块电压的逆变器,所述控制器控制多个电池模块的每个电池模块。多个电池模块包括的第一直流/直流转换器彼此并联连接,并且控制器配置为监控包括电池的电量状态或电池电压的至少一个的电池状态,并且基于电池状态将第一直流/直流转换器控制为接通状态或断开状态。
