 Electric vehicles, EVs, have become a viable solution to the emerging global climate crisis due to their low emissions and high fuel economy. However, the batteries used in EVs require careful thermal management to ensure optimal performance. Liquid cooling is one of the most effective methods of thermal management, but its use in EVs is limited due to the complexity of the cooling system and the potential for leaks. This paper examines several techniques for improving the efficiency of liquid cooling systems, including different configurations, coolant flow, nanoparticles, varying discharging rates, and different coolants. These techniques can help reduce the complexity of the cooling system and improve its overall efficiency. This article was authored by Anisha and Anil Kumar.
