Current Work

My research focus is on developing modular and scalable models of electrical and thermal subsystems of a Battery Electric Vehicle (BEV). I have developed dynamic vapor compression system (VCS) component models for transcritical cycles that were released to the Thermosys toolbox using finite volume (FV) method and conservation equations. I am developing a system model for a BEV with a transcritical vapor compression system, cabin, and battery pack subsystem models. This research also includes designing a control architecture for the thermal management of the cabin and battery pack via the control inputs of the mobile VCS such as compressor and evaporator fan speed and electronic expansion valve (EEV) opening. The model based control will use an objective function that will weight the constraints of the battery pack and the bounds of the cabin temperature for human comfort while minimizing power consumption.
