The conventional battery pack of the electric vehicle is generally arranged in a fixed type or a replaceable type, wherein the fixed type battery pack is generally fixed on the vehicle, and the vehicle is directly used as a charging object during charging. The replaceable battery pack is generally fixed to the vehicle by means of a removable mounting. The battery pack can be removed for individual replacement or recharging operations. And after the replaced battery pack is charged, the battery pack is installed on the vehicle again. At present, the rapid replacement technology of small passenger cars is developed most mature, and the batteries of the passenger cars are all fixed on the chassis of the car, so when the battery pack is replaced, a special battery replacement device is required to be moved to the bottom of the car for battery removal or installation. Moreover, the weight of the passenger car is small, the volume of the battery pack is relatively small, and the operability of battery replacement is very convenient.

However, for large vehicles, such as heavy trucks or light trucks, the weight of the vehicle body and the cargo is large, so that the capacity requirement of the battery pack for the large vehicle is high, and a large enough electric energy is needed to support the large vehicle for hundreds of kilometers.

For example, a chassis type battery replacement mode of a passenger car is adopted. And in the chassis type battery replacement mode, the battery pack can be mounted on the battery replacement vehicle through the battery replacement shuttle vehicle. However, in the process of replacing the battery, the battery replacing shuttle vehicle is easy to move, so that the battery replacing shuttle vehicle cannot safely take and place the battery pack or normally take and place the battery pack, the battery replacing efficiency is influenced, the battery pack can be damaged, and potential safety hazards are generated.
