The invention provides a direct current charging pile and a charging control method. In the direct current charging pile, a charging unit supplies power to a first charging gun, the first charging gun can be connected with a to-be-charged vehicle with a charging interface meeting a first preset standard, and thus the direct current charging pile has a charging function meeting the first preset standard; moreover, the charging unit supplies power to the switching unit, and the switching unit can be connected with the to-be-charged vehicle with the charging interface meeting the second preset standard through the second charging gun so that the direct current charging pile also has a charging function meeting the second preset standard; therefore, the direct current charging pile can be compatible with the charging function of the first preset standard and the charging function of the second preset standard; besides, the switching unit is arranged in the DC charging pile so that the requirement on the electric power safety level of the switching unit is lower than that of an adapter in the prior art, and the compatible transformation cost of the DC charging pile is reduced.

    本申请提供了一种直流充电桩和充电控制方法。在该直流充电桩中,充电单元为第一充电枪供电、第一充电枪可以与充电接口符合第一预设标准的待充车辆相连,从而该直流充电桩具有第一预设标准的充电功能;并且,由于充电单元为转接单元供电、转接单元通过第二充电枪可以与充电接口符合第二预设标准的待充车辆相连,所以该直流充电桩还具有第二预设标准的充电功能;因此,该直流充电桩可以兼容第一预设标准的充电功能和第二预设标准的充电功能;另外,由于转接单元设置于该直流充电桩内部,所以对该转接单元的电力安全等级要求低于现有技术中的适配器,因此该直流充电桩使得自身的兼容改造成本降低。
