PURPOSE:To accurately and stably quickly charge a battery to a predetermined voltage by feeding back a voltage to a controller of a charger through a signal line extended between the charger and an automatic coupler. CONSTITUTION:Signal lines 60P, 60N are extended between an automatic connector unit 30 and a charger 40, connected at one ends to the movable connectors 31P, 31N of the connector 30 and at the other to positive and negative input terminals of a voltage detector 42. Accordingly, a voltage to be fed back to the controller of a charger 41 becomes a voltage between the connectors 31P and 31N, and is compared with a set voltage. Since the voltage drop of a passage from the connectors 31P, 31N to a battery 20 is so small in the degree as to be ignored, the battery 20 can be stably charged to the set voltage. |
