A hybrid system for battery thermal management for electric vehicles
Résumé
Electric cars are limited by the performances of Li-ion batteries. Usually, air or coolant circulation systems are employed as battery thermal management systems. The disadvantages of those systems are their complex implementation, their cost and the phantom electric load. Phase change materials (PCMs), represent a promising solution to achieve passive thermal management. The challenge of this solution is to quickly release the thermal energy stored in the PCMs. A solution proposed is the incorporation of an additional system to discharge the PCM. This hybrid system is presented in this paper.
