Abstract

The invention provides a power supply system of a railway vehicle. The power supply system comprises a power battery arranged on the railway vehicle, a first controllable switch connected between a current collector of the railway vehicle and a power supply end of the railway vehicle in series, a solar power supply device arranged on the railway vehicle, a second controllable switch connected between the solar power supply device and the power supply end of the railway vehicle in series, a station charging device arranged in a charging station, and a control device used for controlling on andoff of the first controllable switch and the second controllable switch, wherein one end of the station charging device is connected with a municipal electric network, and the other end of the stationcharging device is used for connecting the current collector when the railway vehicle stops beside the charging station. The power supply system can power the power battery through both the station charging device and the solar power supply device, thereby relieving power consumption pressure of railway vehicles and saving power.

Description

technical field [0001] The invention relates to the technical field of rail vehicle power supply, in particular to a rail vehicle power supply system. Background technique [0002] At present, photovoltaics, as a clean energy source, are gradually being recognized and promoted. Compared with other energy sources, photovoltaic technology has many advantages: it does not require mechanical components such as thermal power generation and hydropower generation; it does not require any fuel except sunlight; solar energy is renewable and pollution-free. [0003] In recent years, my country's rail transit technology has developed rapidly, and most rail vehicles (such as high-speed rail, Yunba, etc.) are used outdoors with little or no shelter, which creates good conditions for the use of solar photovoltaic power generation. [0004] Therefore, how to combine solar photovoltaic power generation with rail transit construction and use solar energy to provide electric energy to rail t...
