The invention provides a direct current charging pile which comprises a docking station, a power conversion module and a charging gun, and the power conversion module is detachably connected with the docking station. The docking station comprises a heat dissipation device, the power conversion module can be installed in the docking station to work, the docking station is connected with an alternating-current power grid, the power conversion module is connected with the docking station, and the power conversion module converts alternating current output by the alternating-current power grid into direct current needed by the electric vehicle. The heat dissipation device in the docking station takes away heat generated by the power conversion module. The power conversion module can also be detached from the docking station and connected with an alternating current power grid under the condition that no docking station exists, the power conversion module converts alternating current output by the alternating current power grid into direct current needed by the electric vehicle, and the power conversion module can be suitable for an electric vehicle charging scene without a charging pile or an OBC on the vehicle.

    本申请提供一种直流充电桩,直流充电桩包括扩展坞、功率变换模块和充电枪,其中,功率变换模块与扩展坞可拆卸式连接。扩展坞包括散热装置,功率变换模块可以安装于扩展坞中工作,扩展坞连接交流电网,功率变换模块连接扩展坞,功率变换模块将交流电网输出的交流电转化为电动汽车所需要的直流电,扩展坞中的散热装置将功率变换模块产生的热量带离。功率变换模块也可以从扩展坞内拆下,在无扩展坞的情形下连接交流电网,功率变换模块将交流电网输出的交流电转化为电动汽车所需要的直流电,能够适用于无充电桩或者无车上OBC的电动汽车充电场景。
