The invention provides an integrated battery replacement system and method for a battery replacement type excavator, and relates to the technical field of battery replacement of excavators. Comprising a power battery pack, a power battery pack, a main relay and a charging relay are arranged in the power battery pack, the power battery pack, the main relay and the charging relay are used for supplying power to the battery changing type excavator and are connected through wires to form a charging loop, and the main relay and the charging relay are used for jointly controlling connection or disconnection of the charging loop; the charging relay is externally connected with a charging socket which is used for being connected with an external power supply to charge the power battery pack. The integrated part is integrally taken out when the battery is replaced and taken down, the power battery pack is charged at a time, only the integrated part needs to be integrally assembled when the power battery pack is assembled, the battery pack is assembled and taken once in the whole process, the battery pack does not need to be disassembled and assembled for multiple times, the number of times of disassembling the battery pack when the battery is replaced by the battery replacing excavator is reduced, and the problem that the battery replacing time is long is solved.

    本发明提出换电式挖掘机集成式换电系统及方法,涉及挖掘机换电技术领域。包括动力电池包,动力电池包内设置有为换电式挖掘机供电的动力电池组、总继电器和充电继电器,动力电池组、总继电器和充电继电器之间通过导线相连接,构成充电回路,总继电器和充电继电器用于共同控制充电回路的导通或断开;充电继电器外接充电插座,充电插座用于连接外接电源为动力电池组充电。本发明换电取下时将集成部分整体取出,实现一次性给动力电池组充电,装上时也只需要整体装上集成部分即可,整个过程只取一次装一次,不需要多次拆分和安装电池包,减少换电挖掘机换电时拆分电池包的次数,解决换电耗时长的问题。
