“Besides the requirement to make heating systems for electric and hybrid vehicles absolutely safe and highly efficient… weight and the installation space are an important issue for battery-operated vehicles and plug-in hybrids,” Eberspaecher Climate Control Systems GM Dr. Klaus Beetz said in a release.

Eberspaecher Catem’s third-generation high-voltage PTC heater is 30% lighter and takes up less space that its predecessors.

“With the third generation of our high-voltage coolant heater for electric vehicles, we can generate numerous advantages for our customers with respect to weight, installation space and costs,” he said, mentioning improved manufacturing processes as well as an improved product.

Nissan Leaf and Chevy Volt, Volkswagen Too

“As of today, we have already equipped more than 200,000 EVs with our high-voltage heaters,” Beetz said. Production vehicles with equipment from Eberspaecher include the Nissan Leaf and GM’s Chevrolet Volt and Opel Ampera. The newer e-Golf and eUp from Volkswagen also employ Eberspaecher Catem thermal management, the company says.

“We are assuming that this positive international trend will continue,” Beetz said, “with promising prospects for our PTC heaters.”

Air Heaters, Coolant Heaters

Eberspaecher Catem offers a range of high-voltage heaters for different EV types. For Pure battery EVs, “high-voltage air heaters quickly ensure the right comfort.

“If the vehicle has its own water circuit – such as in large electric and hybrid vehicles,” the firm says, “high-voltage coolant heaters are used, which emit tempered air into the passenger compartment through the heat exchanger.”
