Cooling System for Li-ion Battery of Pure Electric Vehicles

Abstract

Experiencing saturation in IC engine technology and gradual evolution in a battery-operated domain, EVs conquer the automotive industries. All forms of Electric Vehicles can assist in improving fuel economy and reducing emissions. Electric Vehicles are considered the most environmentally friendly option for transportation in the future as compared to IC engines. The working, performance, and range of Electric vehicles depend on the efficiency of traction of battery packs. Lithium-ion batteries are considered the most preferred kind of electric vehicle battery because of their high efficiency, long cycle life, and specific energy (Wh/kg). To have a better range, there is a need of maintaining the efficiency and health of Battery packs which may impact due to several parameters. Temperature is the main parameter that needs to maintain at the highest priority to maintain the range of the vehicle. To enhance performance, safety, and efficiency under various operating states, the temperature of the traction battery pack must be kept within its optimal operating temperature range. For EVs, battery management plays a vital role in getting the optimal performance and life cycle of battery packs. In this paper a modified layout of thermal management of Lithium-ion battery packs for the pure electric vehicle has been discussed with the help of MATLAB simulation which helps to maintain the optimal temperature range in three states of battery i.e., Charging state, driving state, and discharging state.
