Abstract

The invention discloses a magnetic-suspension flywheel energy-storage cell used for an electric automobile. The magnetic-suspension flywheel energy-storage cell combines the prior permanent-magnet and active-control magnetic-suspension flywheel cell technologies so that not only is power consumption of a motive-power cell is reduced, but active control of an energy-storage flywheel is also realized and thus the cell can stand arbitrary disturbances of the storage flywheel. The cell is powered by a motive-power cell of the electric automobile and provides auxiliary electrical power for the motive-power cell when the electrical automobile starts, accelerates or climbs and reduces discharging frequency and discharging depth of the motive-power cell and improves discharging characteristics of the motive-power cell so that service life of the motive-power cell is prolonged.

Description

Technical field [0001] The invention involves a magnetic suspension flywheel energy storage battery, especially a magnetic suspension flywheel energy storage battery for electric vehicles, which can be used as an electric vehicle auxiliary power supply. Background technique [0002] Electric vehicles are driven by power batteries. They have the advantages of efficient energy saving, low noise, and zero emissions. Its large -scale applications will effectively solve the problems of energy shortage and environmental pollution.As the main transportation of electric vehicles in the future, electric vehicles put forward certain requirements for the performance and mileage of launching, acceleration, climbing, and mileage, and these properties depends largely on the performance of power battery.The advantages of pollution and self -discharge are the most potential power batteries for electric vehicles.However, due to the disadvantages of lithium -ion battery cost, small battery life, a...
