Analysis and Evaluation Characteristics for Li-ion battery with impacts of ambient temperature on Pure Electric Vehicle

The automotive sector has shifted towards Electrically Powered Vehicles due to the increase in energy demand, the gradual limiting of fossil fuels, and environmental issues. The Efficiency of traction of battery packs affects the performance and range of EVs. Temperature significantly affects the rate of Lithium-ion battery deterioration as well as the performance of the chemical reaction that takes place inside the battery which impacts the overall performance of the vehicle. The internal temperature of the battery leads to the dropdown of resistance which cause lots of heat generation. In the same way, external temperature i.e., ambient temperature also impacts the performance of the battery. An optimal temperature range is required for the better performance of the vehicles. In battery electric vehicles, there is a sharp decrease in driving range in cold conditions as compared to combustion engines, which is the drawback of battery electric vehicles. This paper includes the analysis of Li-ion battery characteristics under different conditions by using the UDDS drive cycle and an analysis of ambient temperature impacts on EV’s range in automotive vehicle operation.
