Background

The electric vehicle (BEV) is a vehicle which takes a vehicle-mounted power supply as power and drives wheels by a motor, and meets various requirements of road traffic and safety regulations. The automobile has a small influence on the environment, so that the prospect is widely seen, but the current technology is not mature.

For the convenience of replenishing electric energy, the manufacturer generally can fill electric pile for installation of private car parking stall or garage, and the rifle that charges through filling electric pile charges, and the rifle that charges need insert electric automobile's the mouth that charges with the rifle that charges, and is similar with the nozzle at filling station. However, the non-professional driver often forgets to pull out the gun and gets on the vehicle to drive, which causes damage to the charging gun or the charging port and increases the maintenance cost. Severe can cause the charging port or the charging gun electrodes to buckle, which can pose a fire risk if shorted. The contact closeness degree of the charging port can influence the conductive effect to a great extent, and if the charging port is external, the position of the vehicle is not the same every time when the vehicle is parked every time, so that the charging head and the charging port cannot correspond accurately.
