Numerical Simulation on Temperature Control of Lithium Ion Battery Pack Using Novel Composite

Abstract In order to realize better thermal management of lithium ion battery pack��a novel method using aluminum��kerosene composite material as temperature buffer is proposed.Simulation is carried out to find the most suitable volume ratio of aluminum to kerosene of the composite for cooling a lithium ion battery pack.The novel method is also compared with the most common ways of cooling with air and water.It is shown that the optimal volume ratio of aluminum to kerosene in the buffering composite is 7��3 and the buffering composite method is superior to water cooling and air cooling under the set conditions in terms of controlling the maximum temperature and temperature difference among the batteries in the pack.
