Abstract
The lithium-ion battery used for an electric vehicle has high capacity of electric generation and long life in repetitive use, and it is very beneficial for efficient energy usage. However, the establishment of thermal management system which ensures the safety in case of abnormal heat generation of the lithium-ion battery cell, is not yet sufficient. Therefore, we proposed a new cooling system using phase change material and heat pipes and investigated its cooling effect. As a result, we found that the temperature of the lithium-ion battery of electric vehicle in driving, could be maintained under 45 deg C by the cooling system.
