The invention discloses a battery pack anti-theft system and a power battery pack anti-theft device and method.The battery pack anti-theft system comprises a detection device, a locking device and a controller, the detection device is connected with the controller, and the controller is connected with the detection device and the locking device. The locking device is positioned at the tail part of the battery pack mounting bolt with the slotted tail part; and the detection device is used for sending a detection signal to the controller when detecting that the axial movement amount of the battery pack mounting bolt of which the tail part is slotted exceeds a movement threshold value. Whether the bolt is withdrawn or not is sensed through the detection device, if the bolt is unscrewed and withdrawn, a detection signal is sent out for anti-theft early warning, when the controller receives the detection signal to inform a user and a vehicle owner sends a vehicle locking command, the controller sends a locking signal to the locking device, the locking device controls the spring bolt to stretch out after receiving the locking signal, and active locking is achieved. The bolt is prevented from being unscrewed continuously.

    本发明公开了一种电池包防盗系统、电动汽车用动力电池包防盗装置和方法,电池包防盗系统包括:检测装置、锁定装置和控制器,其中,所述检测装置与所述控制器连接,所述控制器分别连接所述检测装置和所述锁定装置,所述锁定装置位于所述尾部开槽的电池包安装螺栓的尾部;检测装置,用于在检测到尾部开槽的电池包安装螺栓的轴向移动量超过移动阈值时,发送检测信号给所述控制器。通过检测装置感知螺栓是否退出,若出现拧松退出,则发出检测信号进行防盗预警,控制器接收到检测信号通知用户,车主发出锁车命令时,控制器发出锁定信号给锁定装置,锁定装置收到锁定信号后控制锁舌伸出,实现主动锁止,防止螺栓继续拧松。
