Ev Charging Facility And Operation Method

Abstract: Provided is an EV charging facility comprising: a plurality of charging stands that, by being attachably/detachably connected to EVs, charge power storage devices mounted to the connected EVs; a plurality of power supply circuits that convert power fed from a power system side into DC power corresponding to the EVs and feed the converted DC power to any of the charging stands; a charging and discharging stand that, by being attachably/detachably connected to an EV, charges and discharges a power storage device mounted to the connected EV; and a bidirectional converter that performs bidirectional power conversion in a direction in which the power storage device of the EV connected to the charging and discharging stand is charged and a direction in which the power storage device of the EV connected to the charging and discharging stand is discharged. Accordingly, it is possible to provide an EV charging facility which comprises a plurality of charging stands and which can reduce contracted power with a simpler configuration, and an operation method therefor.
