Stationary charging system

Provided is a stationary charging system that is capable of battery charging even when a charging unit has a fault. A stationary charging system 1 for charging a battery mounted in a vehicle includes a power unit 2 for generating direct-current charging power, a plurality of charging units 3 (CHG1 to CHG9) that constitute the power unit 2, a control unit (MCU) 5, and a first CAN communication line 6 for allowing data exchange between the control unit 5 and the charging units 3, the charging units 3 create charging unit status data concerning results of fault diagnosis on themselves, and transmit the data to the control unit 5, and the control unit 5 classifies the charging units 3 into a plurality of charging unit groups 4-1, 4-2, and 4-3, and changes output statuses of the charging units 3 for each of the charging unit groups upon reception of charging unit status data indicative of a fault.
