Abstract: A relay device provided in vehicle having a battery, converting control signal formats, and relaying same between: a first communications unit that sends and receives control signals in a first format relating to charging; and second communications unit that supplies DC voltage, is provided in a charging station that charges battery, and sends and receives control signals in a second format relating to charging. The relay device includes: a limiting unit that limits power supplied between charging station and battery, regardless of vehicle side control performed on control signals' basis; an acquisition unit that obtains DC voltage supplied by charging station and obtains the battery's voltage; a determination unit that determines whether the voltage difference between each obtained voltage is less than threshold value; and a release unit that releases the limits by limiting unit if a determination has been made that the voltage difference is less than threshold value.
