The present invention relates to an electric vehicle charging device with a removable relay board, and more particularly to an electric vehicle charging device capable of multichannel configuration of the charging device through a three-phase, four-wire power supply using a bus bar or bus duct means capable of carrying large currents by modularizing a relay configured in the electric vehicle charging device. More particularly, the present invention relates to a relay board detachable electric vehicle charging device, which has the convenience of modularizing relays with a high relative failure probability in electric vehicle charging devices into a separate board (relay board), so that in the event of a failure of an electric vehicle charging device installed in the field, a non-expert can quickly repair it by removing and replacing the relay board without the help of the charging device manufacturer, and which has the expandability to increase the power of a charger by attaching and installing a relay board larger than the capacity of the existing relay of the electric vehicle charging device, and which can reduce additional costs by placing a bus bar (horizontal) or bus duct (vertical) that can flow large currents supplied by three-phase four-wire power inside the charger to increase the capacity of the charger and expand the number of channels (basic 1 channel ⇒ 2 channels ⇒ 3 channels) by removing and attaching the relay board.
본 발명은 릴레이보드 탈부착형 전기자동차 충전장치에 관한 것으로서, 상세하게는 전기자동차 충전장치에 구성되는 릴레이(Relay)를 모듈(Module)화하는 것과 대전류를 흘릴 수 있는 Bus bar 또는 Bus duct 수단을 사용하여 3상 4선식 전원 공급을 통해 충전장치를 다채널로 구성할 수 있는 전기자동차 충전장치로서, 보다 상세하게는 전기자동차 충전장치에서 상대적 고장 확률이 높은 Relay를 별도의 보드(Relay Board) 형태로 Module화하여 현장에 설치된 전기차 충전장치의 고장 발생 시, 충전장치 제조사의 도움없이 비전문가 누구나 Relay Board를 탈부착 교체하여 신속하게 수리하는 편리성과, 전기차 충전장치의 기존 릴레이의 용량보다 큰 Relay Board를 탈부착하여 설치함으로서 충전기의 전력을 증설할 수 있는 확장성과, 3상 4선식으로 전원을 공급받아 대전류를 흘릴 수 있는 Bus Bar(수평) 또는 Bus Duct(수직) 등을 충전기 내부에 배치하여 Relay Board의 탈부착을 통한 충전기 용량 증설과 다채널 확장(기본1채널 ⇒ 2채널 ⇒ 3채널) 시, 추가적 비용이 절감될 수 있는 릴레이보드 탈부착형 전기자동차 충전장치에 관한 것이다.
