直流屏充电模块N+1中的N为模块个数，1为备用模块。 直流屏的调试,接通交流电源测试交流双电源切换装置是否工作正常，双电源切换装置的下口电压是否正常。交流部分测试正常后，依次闭合充电模块的交流开关，观察模块是否正常启动并测量模块输出电压和极性。充电模块启动正常并输出电压和极性正确后，接通电池组开关及各母线开关，测量电池组开关下口、合母、控母电压和极性是否正确，并观察电压表计是否方向打翻。 特点 高可靠性： 采用开关电源的模块化设计，N+1热备份。 充电模块可以带电热插拔，平均维护时间大幅度减少。 动力母线和控制母线可以由充电模块单独直接供电，可以通过降压装置热备份。 硬件低差自主均流技术，模块间输出电流大不平衡度优于5%。
