The invention discloses a DCDC converter and a control method. The DCDC converter comprises one or more DCDC conversion modules which are arranged in parallel and are connected between a battery pack of which the rated voltage is a first value and a DC charging pile of which the output voltage is a second value; the DCDC converter is also connected with the main control chip; wherein the first value is greater than the second value; the direct current charging pile is used for charging the battery pack; the first transceiving end of the DCDC conversion module is used for being connected with a direct current charging pile, and the second transceiving end of the DCDC conversion module is used for being connected with a battery pack; wherein the DCDC conversion module is used for reducing the voltage flowing to the direct current charging pile and boosting the voltage flowing to the battery pack. In this way, the direct current output of the direct current charging pile can be converted through the DCDC converter, and then the battery pack is charged.

    本发明公开了一种DCDC变换器及控制方法,包括:连接在额定电压为第一值的电池包与输出电压为第二值的直流充电桩之间的一个或多个并联设置的DCDC变换模块;所述DCDC变换器还与主控芯片连接;其中,所述第一值大于所述第二值;所述直流充电桩用于给所述电池包充电;所述DCDC变换模块的第一收发端用于连接直流充电桩,所述DCDC变换模块的第二收发端用于连接电池包;其中,所述DCDC变换模块用于对流向直流充电桩的电压进行降压,对流向电池包的电压进行升压。这样本发明便能使直流充电桩的直流输出通过DCDC变换器的转换,进而向电池包进行充电。
