Auto manufacturers are increasingly adopting lithium-ion batteries in response to the rapid evolution of electric vehicle technology. These batteries are being integrated into existing vehicles and planned as the primary power source for new models. Many lithium-ion batteries employ air cooling for safety reasons, due to convenience and cost-effective. This study investigates the cooling efficiency of electric vehicle battery packs using a U-shaped domain with various air-inlet sizes and velocities. Results indicate that air intake position and velocity significantly impact the ability to cool the battery pack. Shifting the air intake point from 30 mm to 20 mm lowers the highest temperature by 3.46 K. Increased air velocity causes a ripple-around effect, reducing the temperature in the second part of the battery pack.

Electric vehicles (EVs) have surged in popularity in recent years due to their environmental benefits. The influence of range on air conditioning (AC) power consumption is a critical concern for electric vehicle (EV) owners, particularly in warmer climates. Overcoming obstacles such as a limited vehicle range is necessary for the increased use of electric-powered automobiles. Cabin heating and cooling demand for climate control consumes more energy from the main battery and has been revealed to significantly reduce vehicle range. During peak cooling or heating, the overall power consumption of the AC system takes almost 50% of the energy used for traction. The average reduction in driving range caused by air conditioning (heating and cooling) approximates 33%. The energy usage of an electric vehicle can be considerably decreased by switching the climate control setting to economy mode.
