The researchers reported improved battery efficiency and prolonged lifespan due to the optimized thermal management. 1.1.4. Numerical simulation and experimental validation
Why is a battery cooling system needed?
Generally, the liquid cooling system is needed to maintain the battery temperature below 45°C. b. The electrochemical reaction and self-discharge of the battery during the charging, discharging, and stationary state are affected by the battery temperature.
How does temperature affect battery cooling?
In the whole experiment the li-ion battery is maintained at different higher temperatures, the cold TO is used to cool down the battery hence it gets TO with higher temperatures at the outlet. In this way, the rise in temperature of TO is linked with battery cooling. Fig. 11. Outlet contour for battery cooling system.
How does a battery cooling system work?
In some novel battery systems, the liquid cooling system has been integrated into the battery pack or battery module. The inlet/outlet aluminum tubes, pack side plates, and cooling plates are integrated as a liquid cooling system. The coolant flows in from the inlet, passes through the cooling plates, and finally flows out through the outlet.
