ABSTRACT:
A signal indicative of the remaining capacity of a storage battery for propelling an electric vehicle is transmitted and received between a portable control unit and a communication unit on the electric vehicle. A display request signal for displaying the remaining capacity of the storage battery is transmitted from the portable control unit which has a plurality of indicator lamps corresponding to respective ranges of a rated capacity of the storage battery, to the communication unit. When the display request signal is received by the communication unit, one of the ranges to which the remaining capacity of the storage battery belongs is determined by the communication unit, and a remaining capacity display signal representing the determined range is transmitted from the communication unit to the portable control unit. The remaining capacity display signal is received by the portable control unit, and one of the indicator lamps which corresponds to the range to which the remaining capacity of the storage battery belongs is turned on based on the received remaining capacity display signal for a predetermined period of time.
