Smart parking garages are unmanned, enclosed facilities. After a car enters the parking garage, the driver leaves the cab, and the car is automatically transferred to a parking space by a transport trolley. The entire process is automated and unmanned. How to achieve charging and connection for electric vehicles during this process is a problem that needs to be solved on-site. Existing commercially available are mature AC direct-plug charging devices for electric vehicle charging. These AC direct-plug connectors consist of male and female electrode modules. The female electrode module connects to the charging port... The power transmission lines are fixedly connected together, the male electrode module is plugged into the female electrode module, the male electrode module is connected to one end of the charging gun, and the other end of the charging gun is plugged into the charging socket on the electric vehicle, thus forming a charging path for the electric vehicle. Given the relationship between the transport trolleys and equipment in the intelligent parking garage, there are limitations to the use of charging connectors. It is necessary to ensure the scope and requirements of their use. How to effectively combine the parking and charging of electric vehicles with the parking process, and how to effectively and safely combine the existing mature male and female electrode module plugging methods with the parking process, has become a problem for electric vehicle charging in mechanical intelligent automated parking garages.
