The invention relates to the technical field of power supply control, and discloses a voltage conversion system control method and device, a controller and a vehicle, a voltage conversion system is connected between a power battery and a charging pile, and the charging pile charges the power battery through the voltage conversion system; the method comprises the steps that a power battery and a voltage conversion system are connected based on a power-on instruction; performing voltage platform matching detection on the power battery and the charging pile to obtain a first matching result; if the first matching result shows that the voltage platforms of the power battery and the charging pile are not matched, obtaining a first conversion proportion according to respective maximum voltages, and controlling a voltage conversion system to perform voltage conversion according to the first conversion proportion, so that the charging pile charges the power battery; and based on the power-off instruction, controlling the voltage conversion system to stop working, and disconnecting. The beneficial effects of the invention are that the method achieves the technical effects of enabling devices configured with different voltage platforms to be compatible with each other through voltage conversion, and optimizing the charging efficiency.

    本申请涉及电源控制技术领域,公开了一种电压转换系统控制方法、装置、控制器及车辆,电压转换系统连接于动力电池和充电桩之间,充电桩通过电压转换系统对动力电池进行充电;该方法包括:基于上电指令连通动力电池和电压转换系统;对动力电池和充电桩进行电压平台匹配检测,得到第一匹配结果;若第一匹配结果表示动力电池和充电桩的电压平台不匹配,根据各自的最大电压得到第一转换比例,并根据第一转换比例控制电压转换系统进行电压转换,使得充电桩对动力电池进行充电;基于下电指令,控制电压转换系统停止工作,并断开连接。其有益效果是,实现了通过电压转换,使得配置不同电压平台的设备之间能够相互兼容,并优化充电效率的技术效果。
