Supercapacitor application on electric vehicles
Sep 04, 2018

Nowadays, in the discharge of urban polluting gases, automobiles have accounted for more than 50%, and countries all over the world are looking for alternative fuels for automobiles. As oil shortages become more serious, people are increasingly recognizing the importance of developing new types of vehicles, using oil and other energy sources while minimizing emissions.


The supercapacitor has high power density, short charging and discharging time, good current charging and discharging characteristics, long life and low temperature characteristics superior to the battery. These excellent performances make it have a good application prospect in electric vehicles. In the urban area of the city, the bus runs within 20 kilometers, and the electric vehicle with super capacitor as the only energy source can travel more than 20 kilometers in one charge. It will have broad application prospects in city buses [ 1].


Electric vehicles belong to new energy vehicles, including Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV) and Fuel Cell Electric Vehicle (FCEV). It integrates the latest technologies in the fields of light, machine, electricity and chemical, and is the latest integration of engineering, automotive, electric power, power electronics, intelligent control, chemical power, computer, new energy and new materials. product. There is no difference in appearance between electric vehicles and traditional cars. The main difference between them is the power drive system.
