<p>PURPOSE:To enhance a facility efficiency while charging various storage batteries having different voltages and capacities. CONSTITUTION:One rectifier 21 is provided as a common DC power source for a plurality of chargers 221-223, and switched to an individual operation mode for supplying charging currents individually controlled to loads of secondary cells of an electric road vehicle in the chargers or to a high voltage or high current operation mode for supplying output-controlled high-voltage or high-current charging currents to the vehicle, etc., by switching the outputs of the chargers to a series or parallel connection. Thus, various loads which place storage batteries having various voltage classes and capacities can be charged. Further, an apparent capacity is reduced in a single charger.</p> |
