The invention relates to the technical field of charging terminals, in particular to a direct-current charging terminal and a control method thereof, and the direct-current charging terminal comprises a charging gun, an input switching device and an output switching device; the DC/DC module is respectively connected with one end of the input switching device and one end of the output switching device, the other end of the input switching device is connected to the direct current bus, the other end of the output switching device is connected with the charging gun, the DC/DC module is used for converting the voltage of the direct current bus into a vehicle-side required voltage, and the output switching device outputs the vehicle-side required voltage; and the controller is used for acquiring the charging demand of the target vehicle after the charging gun is connected with the target vehicle, controlling the input switch device, the output switch device and the DC/DC module to output the vehicle side demand voltage based on the charging demand, and charging the target vehicle based on the vehicle side demand voltage. Therefore, the problems that in the prior art, direct interconnection with green power equipment cannot be achieved, no power conversion module exists in the terminal, and the flexibility and efficiency of energy interconnection are limited are solved.

    本申请涉及充电终端技术领域,特别涉及一种直流充电终端及其控制方法,其中,包括:充电枪、输入开关器件和输出开关器件;DC/DC模块分别与输入开关器件的一端和输出开关器件的一端相连,输入开关器件的另一端接入直流母线,输出开关器件的另一端与充电枪相连,DC/DC模块用于将直流母线的电压变换为车辆侧需求电压,输出开关器件输出车辆侧需求电压;控制器,用于在充电枪与目标车辆连接后,获取目标车辆的充电需求,基于充电需求控制输入开关器件、输出开关器件和DC/DC模块输出车辆侧需求电压,基于车辆侧需求电压为目标车辆进行充电。由此,解决了现有技术中无法与绿电设备直接互联以及终端内部无功率转换模块,限制了能源互联的灵活性与效率等问题。
