The invention provides a battery pack locking state monitoring system. The battery pack locking state monitoring system comprises a locking mechanism, a battery pack locking state monitoring mechanism, a battery pack and a vehicle control unit, the battery pack is provided with a battery edge covering beam, and a through hole is formed in the battery edge covering beam; the locking mechanism comprises a lock body and a lock cylinder, the lock body is arranged on the vehicle chassis, the lock cylinder penetrates through the through hole to be matched with the lock body, and the battery pack isdetachably connected to the vehicle chassis; the battery pack locking state monitoring mechanism is electrically connected with the vehicle control unit; the battery pack locking state monitoring mechanism is used for monitoring displacement information of the lock cylinder relative to the lock body, generating loosening state information when the displacement information meets a preset conditionand sending the loosening state information to the vehicle control unit, and the loosening state information is used for reflecting a locking position where the lock cylinder is separated from the lock body; the vehicle control unit is used for generating alarm information according to the loosening state information; the installation firmness of the locking mechanism on the battery pack is judgedaccording to the displacement information of the lock cylinder relative to the lock body, and the method is simple and convenient.
本发明提供一种电池包锁紧状态监测系统,包括锁紧机构、电池包锁紧状态监测机构、电池包和整车控制器;电池包设有电池包边梁,电池包边梁上设有通孔;锁紧机构包括锁体和锁芯,锁体设置在车辆底盘上,锁芯穿过通孔与锁体配合,将电池包可拆卸连接于车辆底盘;电池包锁紧状态监测机构与整车控制器电连接;电池包锁紧状态监测机构用于监测锁芯相对于锁体的位移信息,当位移信息满足预设条件时生成松脱状态信息,并将松脱状态信息发送至整车控制器,松脱状态信息用于反映锁芯脱离与锁体配合的锁紧位置;整车控制器用于根据松脱状态信息生成报警信息;本发明通过对锁芯相对于锁体的位移信息来判断锁紧机构对电池包的安装牢固性,方法简单便捷。
