Power supply battery and power supply system for high-speed maglev trains

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...

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

[0004] On the long-distance running line, in order to realize that the train can continue to supply power to the train when it stops at any point, the current receiving rail (or power supply coil) will be laid on the whole line, which will greatly increase the investment cost of the maglev track, and also increase the maintenance cost and power supply cost. ; Simultaneously, because the train has highly reliable redundancy design, the probability that makes train failure stop is less, and the economic benefit of laying power supply rail (or power supply coil) like this is also very low
