The invention provides a battery pack connecting device which comprises a connecting rod, a heater and colloid, the connecting rod is connected to a battery pack and is provided with a connecting part connected with a vehicle through the colloid, and the heater is arranged on the connecting rod. When thermal runaway of the battery occurs, the heater is connected with a power supply, the heater heats the connecting part of the connecting rod, so that the temperature of the connecting part of the connecting rod rises, the connecting part of the connecting rod enables the temperature of the colloid to rise through heat transfer, and when the temperature of the colloid reaches a melting point, the colloid is changed from a solid state to a liquid state. And the connecting part of the connecting rod is separated from the slotted hole in the vehicle. When the connecting parts of all the connecting rods are separated from the corresponding groove holes, the battery pack is separated from the vehicle, potential safety hazards caused by the battery pack to passengers on the vehicle naturally are prevented, meanwhile, rescue personnel can cool and extinguish the battery pack more easily, the fire extinguishing efficiency of the battery pack is improved, and the life and property safety of a user is ensured.

    本申请提供了一种电池包连接装置,包括连接杆、加热器和胶体,连接杆连接于电池包,并设有通过胶体与车辆连接的连接部,加热器设置在连接杆上。当电池发生热失控时,加热器与电源导通,加热器对连接杆的连接部进行加热,使连接杆的连接部的温度上升,连接杆的连接部通过热传递使胶体的温度上升,当胶体的温度达到熔点时,胶体由固态变化为液态,在电池包重力作用下,连接杆的连接部会脱离车辆上的槽孔。当所有连接杆的连接部脱离对应的槽孔时,电池包与车辆实现分离,防止电池包自然对车辆上的乘员造成安全隐患,同时救护人员更加容易对电池包进行降温灭火,提高对电池包的灭火效率,确保用户的生命财产安全。
