The embodiment of the invention discloses a charging device, a charging method and a charging system, the charging device comprises three charging modules, the first charging module receives a first path of voltage of an AC power grid, converts the first path of voltage into a first output voltage and provides the first output voltage to a first to-be-charged device for charging; the second charging module receives a second path of voltage of the alternating current power grid, converts the second path of voltage into a second output voltage and provides the second output voltage to a second device to be charged for charging; the third charging module receives a third path of voltage of the alternating current power grid, converts the third path of voltage into a third output voltage and provides the third output voltage to a third device to be charged for charging; wherein the first voltage, the second voltage and the third voltage have the same frequency and amplitude, and the phase difference is 120 degrees; and the three charging modules are used for controlling three paths of voltage of the alternating current power grid to charge the first to-be-charged equipment, the second to-be-charged equipment and the third to-be-charged equipment at the same time. Therefore, the charging efficiency can be improved while the cost is reduced.

    本公开实施例公开了一种充电装置、充电方法以及充电系统,该充电装置包括三个充电模块,第一充电模块接收交流电网的第一路电压,将第一路电压转换为第一输出电压并提供给第一待充设备进行充电;第二充电模块接收交流电网的第二路电压,将第二路电压转换为第二输出电压并提供给第二待充设备进行充电;第三充电模块接收交流电网的第三路电压,将第三路电压转换为第三输出电压并提供给第三待充设备进行充电;其中,第一路电压、第二路电压和第三路电压的频率和幅值相同,且相位互差120度;且三个充电模块用于控制交流电网的三路电压为第一待充设备、第二待充设备和第三待充设备进行同时充电。如此可以在降低成本的同时,还能够提高充电效率。
