Abstract 

Thermal management is important to ensure the safe operation and prolong life-span of a lithium-ion battery pack. In order to realize efficient thermal management of lithium-ion battery pack, a novel cooling method coupling metal fins and air flow is proposed. A three-dimensional-dynamic model is used to simulate the temperature profile in a lithium-ion battery. It is shown that the coupling of metal fins and air flow is much more superior to common air cooling in terms of controlling the maximum temperature of the battery and decreasing the energy consumption. The mechanism of cooling enhancement by fins is discussed. The thermal conductivity of the fins proves to be a critical factor which determines the cooling effect.
