Mobile charging device and charging method thereof

A charging method adapted to charge a vehicle, the charging method comprising:

• providing a mobile charging device comprising:
• a charging host, comprising at least one first electrode block and at least one second electrode block, wherein the at least one first electrode block and the at least one second electrode block have different electrical properties, and the charging host is adapted to provide electricity;
• at least two charging plates, respectively corresponding to and being in contact with the at least one first electrode block and the at least one second electrode block;
• a mobile parking plate, comprising a parking plate body and at least two conductive contact blocks, wherein the parking plate body has a first surface and a second surface that are opposite to each other, the first surface is adapted to park the vehicle, the at least two conductive contact blocks are disposed on the second surface, and the mobile parking plate is adapted to move relative to the charging host to be in one of a first position and a second position, wherein the at least two conductive contact blocks are respectively in contact with the at least two charging plates when the mobile parking plate is in the first position, and the at least two conductive contact blocks respectively get away from the at least two charging plates when the mobile parking plate is in the second position;
• and
• a charging gun, disposed on the parking plate body and electrically connected with the at least two conductive contact blocks;
• and
• driving the vehicle onto the first surface of the parking plate body;
• controlling the mobile parking plate with the vehicle parked to move to the first position, so that at least two conductive contact blocks of the mobile parking plate are in contact with the at least two charging plates, respectively, the charging gun, the at least two conductive contact blocks, the at least two charging plates and the charging host are conducted with each other, and the electricity provided by the charging host charges the vehicle parked on the parking plate body through the charging gun;
• and
• when the charging of the vehicle is completed, controlling the mobile parking plate to move away from the first position.
