REALIZATION OF HIGH-VOLTAGE HEATING SYSTEMS FOR THE MODERN ELECTRICAL VEHICLES CABIN

Abstract

Currently, the development of the automotive industry is shifting from classic cars with an internal combustion engine towards cars with combined power plants and electric vehicles. However, the latter’s disadvantage is the relatively low specific energy intensity of the batteries in comparison with hydrocarbon fuel, and, as a result, a smaller power reserve. The limited capacity of the traction battery is get worse by the need to heat the interior of the vehicle. For electric vehicles and electric buses, this task is complicated by the lack of a constant and intense heat source that is found in traditional cars. Thus, providing a comfortable temperature in the cabin of an electric vehicle entails the use of the energy of the traction battery, which ultimately reduces the power reserve. This article discusses the implementation of energy efficient and safe heating of the electric vehicle cabin, presents the existing technical solutions and developments.
