Abstract

A three-dimensional heat dissipation model is built for the lithium-ion battery pack in an electric vehicle. Both simulation and test are conducted on the temperature field of lithium-ion battery pack in a condition of cruise driving and natural air cooling with a result showing their consistency in temperature variation trend, meaning the rationality of the model built. On this basis an optimization scheme for the heat dissipation structure of lithium-ion battery pack is proposed and a simulation is performed. The results indicate that after optimization, lithium-ion battery pack has a good cooling effects: the highest temperature of battery pack lowers from 46°C to 33°C and the temperature difference among the batteries is less than 6°C.
