A charge-status display system which is suitable for use with an electric vehicle. In the charge-status display system, a plurality of detecting means detect the conditions of charging of the electric vehicle, and a determining means determines the results of that detection by the plurality of detecting means. A wireless transmitting means transmits the results of the detection and the results of the determination. Then, a receiving means in a portable remote unit receives therein the results of the detection and the results of the determination, which are transmitted from the transmitting means, and a display means displays the received information thereon. Thus, a charging operator can obtain information about the status of charging of the electric vehicle while at a location remote from the electric vehicle.
