The invention relates to a DC charging pile and a control method thereof, and the DC charging pile comprises a power distribution module, a DC-to-DC module, an energy storage module, an AC-to-DC module, and a charging terminal. A first end of the power distribution module is connected with the energy storage module through the DC-to-DC module, a second end of the power distribution module is connected with an AC power grid through the AC-to-DC module, and a third end of the power distribution module is connected with the charging terminal; the charging terminal is used for obtaining the temperature of the power battery and controlling the power distribution module according to the temperature so that the working mode of the power battery can be switched among a heating mode, a charging mode and a heating and charging synchronous mode. Therefore, by additionally arranging the power distribution module and controlling the power distribution module according to the temperature of the power battery, the heating and charging synchronous mode of the power battery is realized, the time required in the whole charging process is shortened, and the charging speed of the power battery at a low temperature is greatly improved.

    本公开关于一种直流充电桩及其控制方法,所述直流充电桩,包括:功率分配模块、直流转直流模块、储能模块、交流转直流模块和充电终端;功率分配模块的第一端通过直流转直流模块与储能模块连接,功率分配模块的第二端通过交流转直流模块与交流电网连接,功率分配模块的第三端与充电终端连接;充电终端用于获取动力电池的温度,并根据温度,对功率分配模块进行控制以使动力电池的工作模式在加热模式、充电模式、加热和充电同步模式中进行切换。由此,通过增设功率分配模块,并根据动力电池的温度,通过对功率分配模块进行控制,使得动力电池实现加热和充电同步进行模式,缩短了整个充电过程中所需时间,大大提升了动力电池在低温下的充电速度。
