Abstract

本申请涉及一种电池模块、电池组、装置及失效处理方法，电池模块包括：多个用于串联的电池单元，当电池模块失效后，多个电池单元包括失效电池单元和至少一个与失效电池单元相邻的非失效电池单元；和第一连接片，用于连接失效电池单元与至少一个非失效电池单元，第一连接片包括第一连接部和与第一连接部相连的导电部，第一连接部用于与失效电池单元的外壳电气连接，导电部用于与至少一个非失效电池单元电气连接，以使电池模块恢复工作。该电池模块中，无需增设其他部件，仅通过对电池模块原有的连接片进行相应的操作即可，从而减少电池模块的部件数量，降低电池模块结构的复杂性，并能够使得该电池模块具有较高的能量密度。
