The present invention relates to a mutual charge control device of an electric vehicle for a disabled person between a main battery of the electric vehicle for the disabled person and a battery for an electric wheelchair which is placed inside an electric vehicle. The mutual charge control device of an electric vehicle for a disabled person is formed of; the main battery of the electric vehicle for the disabled person; a pair of first and second relays installed between the main battery of the electric vehicle for the disabled person and the battery for the electric wheelchair; and a mutual charge control unit which turns on the first relay and charges the battery for the electric wheelchair from the main battery of the electric vehicle when it is determined that the electric vehicle is driving after the driving of the electric vehicle is determined. The mutual charge control unit turns on the second relay and charges the main battery of the electric vehicle from the battery for the electric wheelchair when it is determined that the main battery of the electric vehicle is discharged less than a predetermined voltage. During the driving of the electric vehicle for the disabled person, the battery for the electric wheelchair placed in the electric vehicle is charged from the main battery of the electric vehicle. Therefore, a current is periodically supplied to the electric wheelchair. If the main battery of the electric vehicle for the disabled person is discharged, the main battery is charged using the battery of the electric wheelchair or an auxiliary battery of the electric vehicle for the disabled person, and then the current is supplied.
