Abstract:

Controlling the temperature of a battery pack within an optimal range and ensuring uniform temperature distribution are the key to improving battery life. With the elevating energy density of batteries, more efficient and energy-saving thermal management system is urgently required for improving electric vehicle (EV) performance in terms of safety and long-term durability. In this work, a novel hybrid thermal management system towards a high-voltage battery pack for EVs is developed. Both passive and active components are integrated into the cooling plate to provide a synergistic function. battery pack incorporated with electrical, mechanical and thermal management components was designed, manufactured and integrated. As the core hardware, a pack-level cooling plate set was innovatively designed by integrating with phase change material (PCM). The radiators that are used in fuel cell-based electric vehicles are at least twice the size of IC engine radiators. This leads to vehicle overloading and an increase in fuel consumption. This paper gives a review of the thermal management system used for the battery of the electric vehicle and the use of PET material in the intake of the cooling system.
