An electric vehicle is driven by electricity from its battery which releases heat energy. If the battery did not transfer the heat energy to outside efficiently, its temperature would start to increase. When the temperature rises above 60℃, the battery performance will drop off due to chemical breakdown which causes cycle life to decrease. Therefore, a battery cooling system is necessary to have the battery operated in an ideal working temperature range. In this study, the performance of an air-conditioning system that has two evaporators to cool the cabin and the battery down simultaneously was measured by varying the outdoor temperature and the ratio of mass flow rate. The experimental results showed the battery-cooling system could be a reasonable auxiliary cooling system.
