Abstract:
1. A stationary charging system for charging a battery mounted in a vehicle using direct-current charging power generated on the basis of alternating-current input power, the system comprising: a power unit for generating the direct-current charging power on the basis of 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 first CAN communication line for allowing data exchange between the control unit and the charging units, wherein, each of the charging units receives control command data transmitted by the control unit, and creates charging unit status data concerning the status of the charging unit, and the control unit divides the charging units into a plurality of charging unit groups, and sets times at which to transmit the control command data such that transmission to at least one of the charging unit groups occurs at a different time from transmission to the other charging unit groups, whereby the charging unit status data from the charging units is received at varying times.
