Résumé:
Lithium-ion (Ii-ion) batteries are considered as the best choice available for energy storage system (EES) for portable devices, electric and hybrid vehicles and smart grid, thanks to their high energy and power densities, lack of memory effect and life cycle. However, the heat generated by these batteries remains a challenge. Without an appropriate battery thermal management system (BTMS), the Ii-ion battery surface temperature can increase very quickly, and thus creating a hazard for the users and the equipment. This paper presents a solid-state hybrid active/passive BTMS system. It includes Peltier effect heat pumps, heat sinks, heat spreaders and fans. It is designed with the objective of regulating the operating temperature of the battery cells while minimizing the parasitic power used to operate the BTMS. After its construction, C/1, 3C and 5C continuous discharge current tests were applied under ambient …
