The present invention relates to an electric vehicle charging apparatus for cutting off standby power when an electric vehicle is not charged. The present invention includes an insulated transformation device connected to a power system on a primary side and including the primary side and a secondary side which are electrically insulated from each other, and a charging station connected to the secondary side of the insulated transformation device and charging the electric vehicle, wherein the insulated transformation device includes an insulated transformer for supplying power applied from the power system to the charging station and a switching unit connected between the power system and the insulated transformer and cutting off the standby power when the charging station does not charge the electric vehicle. Accordingly, the present invention can remarkably reduce the standby power leaked from the power system.
본 발명은 전기자동차를 충전하지 않을 때 대기전력을 차단하는 전기자동차 충전장치에 관한 것이다. 본 발명은 1차측에 전력계통이 연결되며 1차측과 2차측이 전기적으로 절연된 절연변압장치, 및 상기 절연변압장치의 2차측에 연결되어 전기자동차를 충전하는 충전스테이션을 포함하고, 상기 절연변압장치는 전력계통에서 인가되는 전력을 충전스테이션에 공급하는 절연변압기, 및 전력계통과 절연변압기 사이에 연결되며 충전스테이션이 전기자동차를 충전하지 않을 때 대기전력을 차단하는 스위칭부를 포함한다.
