The invention provides a charging pile and a charging method thereof. The method comprises the steps: an external three-phase AC power grid 380V is connected to an AC interface, a voltage regulation control module carries out rectification and voltage regulation of the current and voltage of the external three-phase AC power grid by controlling a silicon controlled rectifier module to a charging voltage value of a to-be-charged device, and signals are transmitted to the to-be-charged equipment for charging through the output interface. A boost circuit and a step-down circuit arranged in the prior art are removed, the phenomenon that heating is serious when the boost circuit and the step-down circuit conduct voltage regulation is overcome, a passive rectification module in the prior art is replaced by the silicon controlled rectifier module, rectification and voltage regulation can be conducted, and therefore power consumption is reduced, and the charging efficiency is improved.
本申请提供一种充电桩及其充电方法,其方法包括:外部三相交流电网380V接入交流电接口,调压控制模块通过控制可控硅整流模块对外部三相交流电网的电流电压进行整流调压到待充电设备的带充电电压值,并通过输出接口输送至待充电设备进行充电。去除了现有技术中设置的升压电路和降压电路,克服了升压电路和降压电路进行调压时出现发热严重的现象,并且将现有技术中无源整流模块换成可控硅整流模块,既可以进行整流还可以调压,从而降低功耗,提高充电效率。
