An attachment module constructed to enable a vehicle charging robot to attach to a vehicle and to thereafter insert its charging connector into the vehicle's charging socket. Once the vehicle is charged and the charging connector is disconnected from the charging socket, the attachment module is further constructed to enable the robot to detach from the vehicle.

A charging pile, and a device, system and method for testing a charging pile are provided. An inner side of a port of one of the gun bases is connected to an inner side of the same port of the other of the gun bases. An outer side of each port of each gun base connected to a port of a charging gun connected to the gun base, so that the two charging guns are connected. In addition, one of the two charging guns operates in the forward output state and serves as tested gun to be tested. The other of the two charging guns operates in the reverse conversion state and serves as a testing gun to test the tested gun. The gun base controller saves and exports the communication data on the communication bus between the two charging guns.
