Battery electric vehicles become an increasingly interesting alternative to conventional vehicles with combustion engine as the costs decrease and the driving range improves. Although, the significant decrease of the driving range at very hot or cold ambient temperatures is still an issue that needs to be solved in order to further improve the adoption of battery electric vehicles. In this chapter a system for energy efficient cabin heating consisting of a heat pump system, a so-called smart seat and radiation heating panels is presented. By means of simulations the possible reduction of energy consumption and increase of driving range during an NEDC is evaluated.
