The invention discloses a novel lithium battery double-gun charging system and a charging method. The system is characterized by comprising a lithium battery BMS slave, a lithium battery external output control module, a lithium battery thermal management module, a lithium battery pack, a lithium battery fault information acquisition and display module, current acquisition equipment, a lithium battery power supply management module, a lithium battery power-on and power-off control module and a lithium battery double-gun charging module, wherein the lithium battery thermal management module, the lithium battery external output control module and the current acquisition equipment are electrically connected with the lithium battery pack respectively. A structure in which one high-voltage box is provided with two battery boxes is adopted, and two parallel modules are arranged in each of the two battery boxes. Once one battery box goes wrong, the battery box can be replaced, so that the maintainability is improved. The two MSDs can be pulled up during maintenance so as to avoid danger during maintenance.

    本发明公开了一种新型锂电池双枪充电系统及充电方法,其特征在于包括锂电池BMS从机、锂电池对外输出控制模块、锂电池热管理模块、锂电池组、锂电池故障信息采集及显示模块、电流采集设备、锂电池电源管理模块、锂电池电源管理模块、锂电池上下电控制模块、锂电池双枪充电模块,锂电池热管理模块、锂电池对外输出控制模块及电流采集设备分别与锂电池组电连接。采用一个高压箱带两个电池箱结构,两个电池箱内分别有两并模组,一旦其中有一个电箱有问题,则可以更换其中一个电箱,增加可维护性,两个MSD可在维修时拔掉,以免在维修时发生危险。
