Abstract

The present invention proposes a power supply system for a rail vehicle, comprising: a power battery arranged on the rail vehicle; a first controllable switch connected in series between the current collector of the rail vehicle and the power supply end of the rail vehicle The solar power supply device, the solar power supply device is arranged on the rail vehicle; the second controllable switch, the second controllable switch is connected in series between the solar power supply device and the power supply end of the rail vehicle; the platform charging device arranged on the charging station, One end of the station charging device is connected to the city grid, and the other end of the station charging device is used to connect the current collector when the rail vehicle stops at the charging station; the control device is used to control the first controllable switch and the Closing and closing of the second controllable switch. The power supply system can not only charge the power battery through the platform charging device, but also charge the power battery through the solar power supply device, thereby alleviating the power consumption pressure of rail vehicles and saving energy.

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...
