Abstract:

The rapid development of lithium ion battery has provided a broad space for every profession and trade, but the temperature change of the lithium ion battery is relatively sensitive, should strengthen the lithium ion battery thermal management system. In this paper, using COMSOL MUTILPHYSICS software, the lithium-ion battery forced convection cooling numerical simulation research , comparing its temperature changes. We conclude: when forced convection temperature is high, the flow speed is high, the cooling effect is better; near the cooling entrance closer, the cooling effect is more obvious, and has important significance to the lithium ion battery radiating and rational utilization.
