The present invention provides a DC charging system. The charging system includes a DC bus for forming a DC voltage; N (N is a natural number of 2 or more) charging terminals which are installed in the outdoors without an awning, share the DC bus, perform DC/DC conversion on the power supplied from the DC bus, and supply the converted power to a vehicle; and a central power device which is installed in a facility for an awning, performs AC/DC conversion to convert AC power into DC power, supplies the converted power to the DC bus, and has available processing power less than a sum of the available processing power of the N charging terminals. It is possible to manufacture a DC charging system having high charging power at low costs.

    본 발명은, 직류전압이 형성되는 직류버스; 차양이 없는 야외에 설치되고, 상기 직류버스를 공유하며 상기 직류버스로부터 공급되는 전력을 DC/DC 변환하여 차량으로 공급하는 N(N은 2 이상의 자연수)대의 충전단말; 및 차양이 가능한 시설에 설치되고, 교류전력을 직류전력으로 AC/DC 변환하여 상기 직류버스로 공급하며, 상기 N대의 충전단말의 가용처리전력량의 합보다 적은 가용처리전력량을 가지는 중앙전력장치를 포함하는 직류충전시스템을 제공한다.
