Ev Charging/Discharging System

Abstract: Provided is an EV charging/discharging system comprising: a plurality of charging/discharging stands that are detachably connected to an EV so as to perform charging and discharging of a power storage device mounted on the connected EV; a plurality of bidirectional converters that are provided to correspond to the plurality of charging/discharging stands and perform bidirectional power conversion in a direction in which a power storage device of an EV connected to a corresponding charging/discharging stand is charged and a direction in which the power storage device of the EV connected to the corresponding charging/discharging stand is discharged; and a control device for controlling the operation of the plurality of bidirectional converters. The control device controls the operation of the plurality of bidirectional converters such that the EV connected to each of the plurality of charging/discharging stands has a target charging rate at the end of parking. Accordingly, provided is an EV charging/discharging system with which it is possible to more effectively utilize an EV power storage device while further increasing the convenience of an EV user.
