Design of a Human-centric Auto-Climate Control System for Electric Vehicles
As the global automotive industry makes a critical transition from the traditional ICEVs (Internal Combustion Engine Vehicles) to EVs (Electric Vehicles), it faces two conflicting technological challenges: 1) range degradation in cold weather conditions and 2) reducing time to thermal comfort in winter driving in absence of waste heat from the IC engine. Next to the EV drivetrain, the HVAC system is the highest consumer of electric power in the vehicle. A recent study conducted by AAA showed that interior heating can reduce the EV range by up to 41% at 20 deg. F (https://apnews.com/article/04029bd1e0a94cd59ff9540a398c12d1). Also, in 2018, the average urban commute in the United States was roughly 27 minutes (https://www.washingtonpost.com/business/2019/10/07/nine-days-road-average-commute-time-reached-new-record-last-year/). So, it is necessary to get the driver to a thermally comfortable state as quickly as possible to make EVs attractive to consumers.
