电池测试系统在废旧动力电池模组回收中应用

Application of battery testing system in recycling used power battery modules

针对现有的废旧动力电池火法回收工艺中单体电池放电时间过长的问题,将一段式电池单体放电方式改为先采用电池测试系统对电池模组进行放电至3.2V,再采用常规的放电设备进行放电至安全电压的方式。通过实验得出,采用电池测试系统进行放电可使整体放电效率提高40%以上,同时能将模组内的残余电量回收68%。

In order to solve the problem that the discharge time of single battery is too long in the existing uesed power battery recovery process,the one-stage single battery discharge method is changed into the method that the battery test system is used to discharge the battery module to 3.2 V,and then the conventional discharge equipment is used to discharge to a safe voltage.The experimental results show that the overall discharge efficiency can be increased by more than 40%and the residual power in the module can be recovered by 68%.
