The invention provides an implementation method of a battery-changing type new energy freight traction locomotive, which is characterized in that a core high-voltage circuit topology can realize dual-source power supply of two energy storage devices with different voltage levels, namely a motor vehicle-mounted energy storage device and a battery vehicle energy storage device, and output contactors of the motor vehicle-mounted energy storage device and the battery vehicle energy storage device can be closed at the same time; the high-voltage topology and the matched battery vehicle-mounted energy storage device battery replacement mode belong to key innovation points to be protected, and the high-voltage topology and the matched battery vehicle-mounted energy storage device battery replacement mode belong to the key innovation points to be protected.

    本发明提供一种换电式新能源货运牵引机车实现方法,其核心的高压电路拓扑可以实现动力车车载储能装置和电池车储能装置两种不同电压等级的储能装置双源供电,动力车车载储能装置和电池车储能装置的输出接触器可同时闭合,共同为动力车高压母线供电(因电池车储能装置电压高,实际动力车储能装置处于热备状态),这种高压拓扑以及配套的电池车车载储能装置换电方式属于本案想要保护的关键创新点。
