Automotive Interior Heating
Heating Systems for Electric Vehicles
Interior heating systems of conventional vehicles with Gas or Diesel engines utilize waste heat from the engine in order to warm the passengers. Unfortunately in electrically powered vehicles this waste heat is no longer available. Conventional heating systems proved to be inefficient by consuming a lot of electrical energy and it is known that the range of electric cars in winter is greatly reduced.
The “Liteheat” heating technology developed by Villinger is the game changer in heating systems for electric cars. By the high energy efficiency of the “Liteheat” system, where electrical energy is directly converted into heat energy, the energy to be expended can be significantly reduced while comfort is increased and system weight is reduced.
The “Liteheat” heatings system increases vehicle range in winter operations of every electric car.
Tests showed that even the most advanced EV increases battery consumption in winter operation (-20C ) from 200Wh/km to 300Wh/km (50% increase! ) which decreases vehicle range by a big margin. With the energy efficient LITEHEAT cabin heating solution vehicle range is greatly extended.
Heating Systems for increased Comfort
Today’s state-of-the-art cabin heating systems use hot air vented through a number of small openings in the cabin. High volumetric air flow is necessary to maintain comfortable cabin air temperatures.
These systems often create uncomfortable air drafts and cold spots inside the passenger compartment. Additionally they require fairly long periods of time to achieve the desired interior air temperature and even then many surfaces of the cabin remain uncomfortably cold.
Efficient Heating System
LITEHEAT is a new heating technology for cabins that creates the same thermal environment and comfort levels that you’d expect at home.
Utilizing a unique, electrically heated coating technology that can be applied on a variety of surfaces in the cabin, it is the first cabin heating system to rely on infrared radiation (IR) rather than convective heating. An IR source transfers heat to a body or object at a distance, exactly how the Sun warms the Earth. It is therefore guaranteed to be a much more pleasant and comfortable experience for passengers. If contact heat is required, LITEHEAT systems can be manufactured accordingly to reduce the infrared emissions and generate contact heat only.
