Abstract

One auxiliary flywheel battery power source is increased on the basis of main power supply of electric car so as to regenerate and store the feedback energy of braking and to assist powering during acceleration and climbing. The auxiliary power source system consists of flywheel battery unit and DC/DC converting regulator. The small flywheel power source system can prolong the service life of the main power supply and the flywheel battery with great power density can assist the main power supply to improve the acceleration performance of the electric car. The present invention is easy to reconstruct the power supply system of electric car, and the technology may be used widely in electric car, electric motorcycle, electric bicycle, electric tricycle, etc.

Description

technical field

[0001] The invention belongs to the technical field of electric vehicle drive control, and relates to a method for constructing an electric vehicle drive system that uses a flywheel battery as an auxiliary power supply and has an energy regenerative braking function and a short-term power boost function. The system can be applied to the field of electric vehicles. It can also be further extended and applied to electric vehicles such as electric motorcycles, electric tricycles, and electric bicycles. Background technique

[0002] An important factor that restricts the wide application of electric vehicles is their short mileage, and regenerative braking is the key to saving energy and increasing the mileage of electric vehicles. It has significant economic value and social benefits. At present, many experiments at home and abroad It has been implemented in the car. The regenerative braking on the existing electric vehicle is to make the motor work in the gene...
