According to the grid-connected and off-grid bidirectional direct-current pile provided by the invention, the fan system is connected with the second power supply output of the direct-current power supply module, so that the fan system can directly take power from the second power supply output of the direct-current power supply module, and the power of the part does not need to be converted by the alternating-current power supply module; only the direct-current power supply module is arranged to reserve the power conversion capability of the corresponding part, and the power redundancy of the corresponding part of the alternating-current power supply module is reduced.

    本发明提供一种并离网双向直流桩,通过将风扇系统与直流供电模块的第二路供电输出相连接,以使风扇系统能够直接从直流供电模块的第二路供电输出取电,进而无需交流供电模块对这一部分的功率进行转换,仅设置直流供电模块保留相应部分的功率转换能力即可,减少了交流供电模块相应部分的功率冗余。
