The demand for reduction in CO2 emissions has led to an increase in electrification of the power train - covering the span from hybrid vehicles to purely battery driven vehicles. The resulting deficit in heat dissipation from the engine calls for a decoupling of the heating of the passenger compartment from the engine waste heat. As a consequence, customized independent heating systems for each particular type of vehicle are required. Both electric and fuel-operated heating systems, guarantee optimally combined a rapid and efficient heating of the passenger compartment. This article demonstrates in general possible heating concepts with the main focus on the heating of the compartment of passenger cars with electric power trains and rates the concepts in dependency of its heating power and the heat deficit due to ambient conditions. Afterwards it is described in detail how to heat a vehicle with electric drive with a fuel-operated heater.
