Abstract: Development of hybrid electric vehicles is of great interest to the transportation industry due to increased demand and cost of gasoline and diesel oil, uncertainty in the steady supply of oil, and increased standards for reduced emissions. This necessity for reducing fuel consumption and emissions led to the development of the concept of hybrid electric vehicles which is dual powered by gasoline or diesel engines with larger battery, hybrid powertrain and electric motors. This leads to improved performance, lower gas consumptions and lower CO2 emission. Electrical energy is lost from electric vehicles in the form of heat during dynamic braking. Recovering this energy using a regenerative braking system and storing it in battery stacks and using it later for propulsion and acceleration can improve the overall efficiency and reduction of fuel consumption. Lithium-Ion batteries are considered as one of the leading types as compared to the other batteries for the battery systems to be employed in electric vehicles (EVs) or hybrid electric vehicles (HEVs). Some of the major challenges with the full-scale commercial use of Lithium-ion batteries for electric or hybrid vehicles are the requirement of high energy and power densities, compatibility with high charge and discharge rates for different load cycles while maintaining high performance, and prevention of any thermal runaway conditions. Recent research and development activities, major technical issues and future research focus of electric battery are reviewed. Experimental, modeling and simulation analysis is presented for electrochemical and thermal characterization of a lithium-ion battery subject to a range of charge and discharge loading, and thermal environmental conditions.
