별도의 부품이나 장치의 추가 없이 기설치된 차량 탑재형 충전기를 활용하여 낮은 직류 충전 전압을 승압하여 더 높은 전압의 배터리를 충전할 수 있고, 충전 뿐만 아니라 V2G, V2L 등과 같은 다양한 활용이 가능한 멀티 포트 충전기가 개시된다.
Disclosed is a multi-port charger that can charge a higher voltage battery by boosting a low direct current charging voltage by using a pre-installed vehicle-mounted charger without additional parts or devices, and can be used for various purposes such as V2G, V2L, etc. in addition to charging. The multi-port charger, according to various embodiments, can easily convert the voltage provided from a charging facility or the magnitude of the voltage of a battery by appropriately utilizing a decoupling circuit provided for decoupling without adding a circuit such as a separate converter, etc., and can reduce the cost for building additional conversion devices or new infrastructure required to charge electric vehicles equipped with newly released 800V batteries by utilizing existing 400V charging facilities.
