Researcher Tuteln on Power Saving Heating for E-Cars-researcher

In the e-car the principle applies: everything costs somehow electricity – and thus reach. This is especially true for the heating. Because there are no waste heat as the burner that can be distributed in the interior. Not a few do without the wheel on heating or air conditioning, studies have shown. Better a less pleasant ride than to stay with empty battery anywhere with an empty battery. Researchers and developers therefore seek high pressure after efficient heating process – and are apparently in nanomaterials, reports “ “

“Intelligent charem management” is a central prerequisite for optimal ranges in winter temperatures, says car expert Ferdinand DudenhOffer. Already loading in a heated garage make a positive noticeable – but also the approach to produce a large part of the “feel-good temperature” over the less energy-intensive seat and steering wheel heating. These needed together with about 0.15 kW only about two percent of the power of electric heating in an electric car. The meaning only one kilometer rich loss at 100 kilometers.

Another possibility are heat pumps. DudenhOffer appreciates that developments in this area will make rise in winter-wide increases from 20 to 25 percent in the future. Thus, the richness losses caused by winter temperatures of 30 to 40 percent to a large extent.

In the future, two-dimensional materials such as graphs and carbon nanotubes may possibly solve the problem. Whose immense potential, among other things, want to explore chemists from the University of Jena together with partners from research and industry, it says at “ “. Thus, about conductive coatings from graphene could now even be printed in the form of ink on surfaces. Similar applications could prevent the fogging of windows.

In Bissendorf near Osnabruck, the company Osnatech is working on the development of electrical heating systems based on carbon nanotubes, it continues to say. In March, the development of a fanless infrared surface heating system for vehicle interiors started. The project is funded by the Federal Ministry of Economics.

The Carbon Nanotube Technology (CNT) is a “quantum leap from heating technology,” says Bene Nintemann, founder and shareholder of Osnatech. The carbon particles of 4 to 6 nanometer diameters conducted electrical current about a thousand times better than copper. Resistors made therefrom are able to convert electrical energy to heat with nearly 100 percent efficiency and generate infrared radiation of 97 percent density.

  1. In contrast to the burner you can park the heat generation at the E-Car. When I stretch alone in winter until 20km, I only set the disc heating and seat heating. I do not want to heat the interior. That would be the purest energy waste. In general, you have a jacket in winter. On long-distance the heating is not so important if the interior is warm first. I then drive without jacket.


  2. The resistors made therefrom are able to convert electrical energy to heat with nearly 100 percent efficiency

    In what else should they transform it? Sounds Pr-Lasty.

  3. The whole thing sounds like the usual PR chatter. Even the saying “a quantum leap” is ridiculous if you know that a quantum leap is called the smallest possible change. It sounds great, however, is in the meaning exactly the opposite of which these PR strategists express my. IR radiant heat can be very uncomfortable for humans. The white one who ever sat in the cold in front of a campfire. Front unbearable hot, neck and back ice cold. Not really healthy. I hold seat heating and steering wheel heating at least for drivers and passenger as more efficient. At the Tesla, even the rear seat is heated.
