Simulation and Measurement of an Energy Efficient Infrared Radiation Heating of a Full Electric Vehicle

Abstract

In full electric vehicles, the energy for heating the passenger compartment has to be taken, contrary to conventional vehicles, from other sources than the waste heat from the internal combustion engine. If the energy is taken from the traction battery, the driving range of the vehicle can in the worst case be reduced by up to 50 %. Other heating concepts require complex additional heating equipment and sometimes even storage tanks and can increase the weight of the vehicle significantly. The topic of this paper is to describe a system of heating up the vehicle interior with reduced energy consumption by using a special heating coating, which can be attached to any carrier material in a vehicle cabin. This coating emits infrared radiation, which is commonly reckoned as very comfortable and an energy efficient alternative to conventional heating concepts.
