Abstract
In a charging fee billing system according to the invention, a preferential card having preferential information stored thereon is issued, the preferential information allowing for an investor having borne costs required for power storage facilities for use in a commercial power system to receive a discount for electricity fees involved in the charging of an electric automobile. When charging is performed for an electric automobile that is equipped with a preferential card, a charging unit set up at a charging stand acquires preferential information from the preferential card. The charging unit bills a charging fee to which a preferential rate has been applied based on the preferential information acquired from the preferential card.
