A direct current charging pile charging control circuit and a direct current charging pile, the direct current charging pile charging control circuit comprises a switch unit having a first connection end and a second connection end, the first connection end is connected with an adjustable charging module in the direct current charging pile, and the second connection end is connected with a to-be-charged device through a charging gun; the driving circuit is used for driving the switch unit to act so as to adjust connection and disconnection between the first connecting end and the second connecting end; the detection unit is used for detecting the voltage between the first connecting end and the second connecting end; and the control unit is respectively connected with the driving circuit, the detection unit and the adjustable charging module. According to the invention, active cut-off and cut-off between the adjustable charging module in the charging gun and the external charging equipment can be realized, so that the switch unit can be switched on to complete charging of the external charging equipment only when the voltage between the first connecting end and the second connecting end is determined to be within a safe range; therefore, the problems of slow charging and overlarge charging current are avoided.

    一种直流充电桩充电控制电路及直流充电桩,直流充电桩充电控制电路包括开关单元,具有第一连接端、第二连接端,第一连接端与直流充电桩内的可调充电模块连接,第二连接端通过充电枪与待充电设备连接;驱动电路,用于驱动开关单元动作以调整第一连接端和第二连接端之间的通断;检测单元,用于检测第一连接端和第二连接端之间的电压;控制单元,分别与驱动电路、检测单元和可调充电模块连接。本发明可以实现对充电枪内可调充电模块与外部充电设备之间的主动切断和断开,进而可以在确定第一连接端和第二连接端之间电压处于安全范围内时,才会接通开关单元以完成对外部充电设备的充电,以达到避免充电缓慢和充电电流过大的问题出现。
