Automatic charging system

An automatic charging system comprising:

• a vehicle, which is driven by power supplied from a power storage device;
• a charger, which is equipped with a charging cable having a charging connector;
• a position information acquisition device for obtaining position information of a charging port of the vehicle located in a parking space;
• a charging robot having a robot arm, which grasps the charging connector and automatically insert and remove the charging connector into and from the charging port;
• and
• a detection device, which detects an operation of the charging port displaced in a vertical direction, wherein
• the charging robot is configured to insert the charging connector into the charging port based on the position information to supply power from the charger to the power storage device for charging,
• and wherein in a case where the detection device detects the operation of the charging port displaced in the vertical direction during a time period from when the position information acquisition device acquires the position information to when the insertion of the charging connector into the charging port is completed, the acquisition of the position information by the position information acquisition device is newly done again.
