Problems solved by technology
Due to the large power supply and high working voltage required by electric locomotives in tunnel engineering, a large number of modules are required to be used in series or in parallel, and the working environment of electric locomotives is relatively complicated. As the working power supply of electric locomotives, the performance of supercapacitors will be affected. The impact of the surrounding environment, too high and too low temperature will affect the life and capacity of the battery; the application technology of supercapacitors in the field of electric vehicles is difficult to apply to tunnel engineering electric locomotives

The invention discloses a high-power super capacitor module matching tunnel engineering electric locomotives. The high-power super capacitor module is formed by connecting N end-to-end super capacitormodules in series. Each super capacitor module is formed by connecting M super capacitor modules in parallel, of which each includes K single super capacitors connected in series. Each super capacitor module is equipped with a BMS node, and each super capacitor module is equipped with a module equalization controller. The beneficial effects of the invention are as follows: the high-power super capacitor module can match tunnel engineering electric locomotives or other equipment requiring different voltage and current levels; and the terminal voltages of the single super capacitors and the working currents of the super capacitor modules can be dynamically and intelligently balanced in the charging and discharging process, so that the service life of the super capacitors can be prolonged, and the energy needs of tunnel engineering locomotives under different working conditions can be well satisfied.
Description
technical field [0001] The invention relates to a supercapacitor module management system, in particular to a high-power supercapacitor module for matching electric locomotives in tunnel engineering. Background technique [0002] my country has a long history of tunnel engineering construction. With the development of various construction undertakings, a large number of tunnel projects have been built, and construction technology and equipment have also been greatly improved. At present, roadheaders are widely used in tunnel construction in our country; the shield tunneling method used in underground excavation has a high technical level.
