“…The required electricity can be generated by solar cells, mounted on the vehicle's exterior. Ackermann et al [19] evidence that area heaters should be mounted close to the body to achieve perfect heat distribution to the body. Their study shows how area heaters contribute to the comfort of the passenger and an energy efficient Heating, Ventilation, and Air Conditioning (HVAC) system.…”

The automotive industry is currently undergoing far-reaching structural changes. Automobile manufacturers are pursuing intensive scientific research and technological development in the field of alternative drive systems, such as electric powertrains. If electric car batteries are charged with regenerative generated electricity, their emission output is zero (from a well-to-wheel view). Furthermore, electric drives have very high efficiency. At cold temperatures, however, the battery power drops due to energy-intensive loads, such as the heating of the passenger compartment, and this consequently reduces the range dramatically. Therefore, the focus of this research work is external energy supply for the required heat capacity. The auxiliary energy may be generated by renewable energy technologies in order to further improve the CO<sub>2</sub> balance of electric vehicles. The paper deals with the design, application, and testing of a biofuel-operated heater to heat the passenger compartment of a battery-powered electric car (a Renault ZOE R240). The practical use of the heating system is analyzed in several test drives, performed during winter 2018. The results as well as the range extension of the electric car that can be achieved by substituting the on-board heating system by the fuel-operated heater are quantified herein.

“…Another aspect driving this development is that R744-based systems can also be operated in heat pump mode to warm up the battery pack (Wehner and Ackermann, 2011;Ackermann et al, 2013). …”

“…By means of a control strategy, areas can be switched off with rising interior temperature gradually. This allows for further reducing the energy demand in the steady state per seat to 120 W (Ackermann et al 2013).…”

“…Classic solutions which are used in conventional vehicles with internal combustion engines such as belt-driven refrigeration compressors, electric windows and seat heaters can only be used very partially in electric vehicles due to the electrical charging of the traction battery, as draining the electric battery for these uses would be counterproductive for the driving range (Ackermann et al 2013). Therefore, innovations in the field of temperature and climate management are essential for electric vehicles especially in Carsharing applications.…”
