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.

    本公开涉及一种直流充电桩及直流充电桩柔性扩容方法。该直流充电桩包括:变换器,与交流电源连接,用于将交流电转换为直流电;充电枪,用于为电动汽车提供直流电;并机口,用于连接其他直流充电桩;多个直流母线,用于为所述充电枪和所述并机口提供电流通路;以及功率分配控制器,用于控制直流电在所述充电枪和所述并机口之间的分配。本公开涉及的直流充电桩及直流充电桩柔性扩容方法,能够使充电桩在满足多台不同类型不同功率等级的电动车同时充电的基础上,提高充电效率和设备利用率。
