The residual power retention capacity is calculated from deteriorating conditions and discharging conditions. The battery managing means confirms a utility rate, an administration cost and an owner. The battery managing means is connected from the transceiver apparatus and a position information terminal using a GPS to a charging stand information providing system through the communication line, and guides the charging stand information providing system.
