The electric automobile is a vehicle which takes a vehicle-mounted power supply as power and drives wheels to run by using a motor, and meets various requirements of road traffic and safety regulations. Because the influence on the environment is smaller than that of the traditional automobile, the prospect is widely seen. Electric vehicles are classified into pure electric vehicles, hybrid electric vehicles, and fuel cell vehicles. With the development of electric vehicles, the related art of battery modules has been increasingly advanced, and nowadays, battery modules have been applied to heavy trucks.
However, due to the limitations of the capacity and volume of the corresponding battery, and the like, a single battery module is not sufficient to support the heavy truck to travel a sufficient distance, so engineers have developed a battery replacement mode for electric vehicles, i.e., a centralized charging station is used to store, charge and distribute a large number of batteries in a centralized manner, and a battery replacement service or a battery charging, logistics deployment and battery replacement service is performed on the electric vehicle in a battery distribution station.
