A new cooling system for lithium-ion batteries in electric vehicles was designed to keep the batteries at the best temperature for optimal performance. The researchers used a modified setup and simulations in MATLAB to manage battery temperature during charging, driving, and discharging. Maintaining the right temperature is crucial for getting the best range and performance from an electric vehicle's battery. By keeping the batteries cool, the new system helps them work better and last longer, making electric vehicles more efficient and reliable for the future.
