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.
L'invention concerne un chargeur à ports multiples qui peut charger une batterie à tension supérieure par amplification d'une tension de charge à courant continu faible à l'aide d'un chargeur monté sur véhicule pré-installé sans parties ou dispositifs supplémentaires, et peut être utilisé à diverses fins telles que V2G, V2L, etc. en plus de la charge. Le chargeur à ports multiples, selon divers modes de réalisation, peut facilement convertir la tension fournie par une installation de charge ou l'amplitude de la tension d'une batterie en utilisant de manière appropriée un circuit de découplage prévu pour le découplage sans ajouter un circuit tel qu'un convertisseur séparé, etc, et peut réduire le coût de construction de dispositifs de conversion supplémentaires ou d'une nouvelle infrastructure requise pour charger des véhicules électriques équipés des nouvelles batteries 800V en utilisant des installations de charge 400V existantes.
별도의 부품이나 장치의 추가 없이 기설치된 차량 탑재형 충전기를 활용하여 낮은 직류 충전 전압을 승압함으로써 더 높은 전압의 배터리를 충전할 수 있고, 충전뿐만 아니라 V2G, V2L 등과 같은 다양한 활용이 가능한 멀티 포트 충전기가 개시된다. 상기 멀티 포트 충전기의 여러 실시예에 따르면, 별도의 컨버터 등과 같은 회로의 추가 없이 디커플링을 위해 마련된 디커플링 회로를 적절하게 활용하여 충전 설비에서 제공되는 전압 또는 배터리의 전압의 크기를 용이하게 변환할 수 있고, 기존에 갖추어진 400V 충전 설비를 활용하여 신규 출시되는 800V 배터리를 구비한 전기 차량을 충전하기 위해 요구되는 추가적인 변환 장치 또는 새로운 인프라 구축 등에 소요되는 비용을 절감할 수 있다.
