(JP8180905-A)      The charger (A) is equipped with a charging section (11) which supplies an electric current to the secondary cell (B) through a connector (6) and a charge control section (10) which controls the charging section (11). The cell (B) is provided with a temperature sensor (5) which is connected to the DC power source of the charger (A) through the connector (6). The control section (10) is connected to either of the terminals of the sensor (5) and stores the range of the voltage applied by the sensor (5) when the cell (B) and charger (A) are connected to each other.    When the voltage applied to the control section (10) is out of the range, the section (10) judges that the cell (B) and charger (A) are not connected to each other.    USE/ADVANTAGE -   E.g. for electric vehicle, or motor vehicle with auxiliary motive power. Does not use any special wiring.
