A New Automatic Charging System for Electric Vehicles

With the continuous advancement of new energy technologies, although the market share of electric vehicles has gradually increased in recent years, due to the problem of charging time, it is difficult to charge electric vehicles. So far, there are no robots on the market that can automatically complete the charging process for different models, because a single robotic arm can only insert and remove the charging gun at a fixed position, and the charging port position of different models is different. This paper proposes a mobile robot charging system based on computer vision, which consists of a rail and a mobile robot equipped with a mechanical arm. First, the vehicle model is judged by the camera mounted on the mobile robot, the corresponding position of the charging port is found on the track, and then the robot is moved to this position, and the insertion and removal of the charging gun is completed through the camera and the mechanical arm. This system has verified the feasibility and the robustness of the algorithm through visual recognition and prototype testing.
