AN ASSESSMENT OF HYBRID ENERGY STORAGE SYSTEMS IN THE

Types of energy storage systems in hybrid electric vehicles

A fuel cell works as an electrochemical cell that generates electricity for driving vehicles. Hydrogen (from a renewable source) is fed at the Anode and Oxygen at the Cathode, both producing electricity as the main product while water and heat as by-products. Electricity produced is used to drive. . A supercapacitor (sometimes Ultra-Capacitor) is the same as a battery that can store and release electricity. In a supercapacitor, no chemical reaction happens rather than charge is stored statically. It has also. . The battery is the most commonly used in present-day EVs. It converts the electrochemical energy into electrical energy. Li-ion battery is very promising for EVs as compared to the Lead-acid battery, the nickel-cadmium. These technologies are based on different combinations of energy storage systems such as batteries, ultracapacitors and fuel cells. The hybrid combination may be the perspective technologies to support the growth of EVs in modern transportation.

Hybrid energy storage systems and battery management for electric vehicles

Power loss during regenerative braking can be reduced by hybrid energy storage system (HESS) such that super-capacitors accept high power as batteries have small rate capability. Conventional charge management does not systematically exchange charge between the supercapacitor and battery.
