Heat pump is an energy efficient and environmentally friendly heating and cooling system. Its working principle is to draw energy from a low-temperature source using a thermodynamic cycle and transfer this energy to a high-temperature receiver.
Heat pumps used in electric vehicles increase the range of the vehicle, reduce energy consumption and improve interior comfort. Equipped with components such as compressor, evaporator, condenser and expansion valve, these systems can operate effectively even if the outside air temperature is low. However, initial investment costs and maintenance requirements can be considered among the disadvantages of this technology.
Heat pumps are an important technology that affects the battery life and range of electric vehicles. In cold weather conditions, an electric vehicle without a heat pump uses electricity directly from the battery to provide cabin heat. This causes the battery to drain faster and therefore reduces the range. In a vehicle equipped with a heat pump, the cabin is heated by using the heat energy taken from the external environment, allowing more efficient use of the battery and increasing the range.
Technical problems such as refrigerant leaks can reduce the efficiency of the heat pump or even render the system dysfunctional. Mechanical wear can cause incorrect operation of valves and pumps, and malfunctions in electronic control units can cause incorrect operation of the system. Under cold climate conditions, the performance of the heat pump may decrease. This may affect the vehicle’s interior comfort and repair costs. Therefore, regular maintenance and checks are critical to ensure long-lasting and efficient operation of heat pump systems.
