Beschreibung
Zusammenfassung:	The utility model discloses a direct-current charging system capable of distributing power, which comprises a direct-current bus, a plurality of power conversion units, a plurality of charging piles and a plurality of relays, the power conversion units are electrically connected with one another through the relays, the input end of each power conversion unit is electrically connected with the direct-current bus, and the input end of each charging pile is electrically connected with the direct-current bus. The number of the power conversion units is equal to that of the charging piles, each charging pile corresponds to one power conversion unit, the same power conversion unit corresponds to at most one charging pile, and the charging piles are electrically connected with the output ends of the corresponding power conversion units. Therefore, during output, different numbers of power conversion units can be started through the switch relay for combined output, and when one power conversion unit cannot meet the
