Thermal management of electric vehicle system
With growing trend towards electric vehicle and hybrid vehicles, development of air conditioning systems became a challenge to automotive manufactures. While, air conditioning systems are not new to industry, electric vehicles and hybrid vehicles requires more advanced air conditioning systems which are capable of cooling and heating both cabin and battery. This is due primarily to battery technology along with motors, inverters and computing resources, all of which require advanced thermal management solutions.
Airconditioning systems for EV/Hybrid vehicles are highly complex though and take a large amount of time and effort to design and can be extremely costly if incorrectly specified. Vapor cycle capabilities of Simcenter Flomaster have been leveraged to model a twin heat exchanger model involving separate battery and invertor cooling loop. Interaction between all the cooling loops are thoroughly evaluated and system is optimized for best performance.
