The disclosure relates to a direct-current charging pile and a direct-current charging pile flexible capacity expansion method. The direct-current charging pile comprises a converter being connected with an alternating-current power supply and being used for converting an alternating current into a direct current, a charging gun being used for providing direct currents for an electric vehicle, a parallel port for being connected with other direct-current charging piles, a plurality of direct-current buses for providing a current path for the charging gun and the parallel port, and a power distribution controller for controlling the distribution of direct currents between the charging gun and the parallel port. According to the direct-current charging pile and the flexible capacity expansion method of the direct-current charging pile, the charging efficiency and the equipment utilization rate can be improved on the premise that the charging pile can charge multiple electric vehicles having different types and different power levels at the same time.
