Electric Vehicles (EVs) have started gaining notable attention from the industry and customers in India over last couple of years. However, OEMs are still cautious for wider customer acceptance of EVs as their products are challenged with expensive component costs, lack of charging infrastructure, issues of driving range anxiety amongst the customers. In such a scenario, OEMs are constantly looking for innovative solutions which will enhance the driving range of EVs by optimizing the power consumption in every possible way. In an electric vehicle, Heating Ventilation and Air Conditioning (HVAC) system is essentially required for providing all season thermal comfort and maintain operating temperature of High Voltage battery pack (HV battery). While catering to such requirements, HVAC system becomes one of the major power consuming aggregate in EVs.

In present day passenger cars, Mobile Air Conditioning (MAC) system is one of the essential features due to rise in overall ambient temperatures and comfort expectation of customers. During the development of MAC system, the focus is on cooling capacity of system for maintaining in-cabin temperatures. However, parameters like solar radiation, air velocities at occupant, relative humidity, metabolic rate and clothing of occupants also influence occupant’s thermal comfort and normally not considered in design of the MAC system. Subjective method is used to evaluate thermal comfort inside vehicle cabin which depends mainly on human psychology. To better understand the effect and minimize the human psychological factors a large sample of people are required. That process of evaluating the comfort inside the vehicle cabin is not only time consuming but also impractical.
