Abstract:
1. A stationary charging system for charging a battery mounted in a vehicle with direct-current charging power generated from alternating-current input power, comprising: a power unit for generating the direct-current charging power from the alternating-current input power; a plurality of charging units that constitute the power unit; a control unit for controlling the charging units; and a CAN communication line for allowing data exchange between the control unit and the charging units, wherein, the direct-current charging power is a sum of output power provided by the charging units, the charging units conduct fault diagnosis on themselves to create charging unit status data concerning results of the fault diagnosis, and transmit the charging unit status data to the control unit, and the control unit classifies the charging units into a plurality of charging unit groups, and changes output statuses of the charging units for each of the charging unit groups upon reception of the charging unit status data indicative of a fault.
