Abstract

The invention provides a power supply battery and a power supply system for high-speed maglev trains. The power supply battery comprises an electrolyte tank, a plurality of liquid flow pumps and a plurality of aluminum-air battery reactors. The aluminum-air battery reactors are sequentially connected in series. The electrolyte tank comprises a plurality of strip-shaped electrolyte grooves. One liquid flow pump corresponds to one aluminum-air battery reactor and one electrolyte groove. The power supply battery and the power supply system for high-speed maglev trains provided by the embodiment of the invention have the advantages of long-term storage without power loss, high energy density, high safety, abundant resources, low manufacturing cost and cleanliness and easy recovery by adoptingaluminum-air batteries as the power supply of an on-board energy storage system of a high-speed maglev train. Moreover, high voltage of the whole power supply battery can be ensured, self-discharge isreduced, high integration of the aluminum-air battery is facilitated, the installation space is reduced, continuous work is realized, and energy can be continuously provided for maglev train loads.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted power supply for maglev trains, in particular to a high-speed maglev train power supply battery and a power supply system. Background technique [0002] At present, the highest test operating speed of domestic high-speed maglev trains has reached 503km / h, and the highest actual operating speed can reach 430km / h. With the passage of time and technological innovation and research and development, there will be higher-speed maglev trains above 600km / h. Then, high-speed maglev trains will inevitably become one of the main means of transportation for long-distance operations. However, the long-distance operation of high-speed maglev trains will also bring new technical problems: how to ensure the comfort of passengers in the train when the train stops due to failure; how to restart and run the train after the failure is repaired. Therefore, on the long-distance running line, when the train fai...
