Ford Tests Heated Interior Panels That Could Lead To More Range In EVs via insideevs.com

According to Ford, the testing took place in winter and summer, on dry and wet roads, and in heavy rain and wind, using the vans for parcel deliveries, special goods deliveries, and a craftsman’s one-day job 350 kilometers away. And when everything was said and done, the math said that the heading elements used 13 percent less energy than the aircon would have used, which led to an average range gain of five percent.
It's worth noting that most of the vehicles involved in the study made short trips where the driver had to open and close the door frequently, which lowered the temperature of the cabin quite a bit. “We all know that if the doors or windows are opened when it is colder outside, the temperature inside a vehicle drops. This is especially true for delivery vans as drivers make frequent drop‑offs and the heat generated via aircon is lost more quickly, while heated surfaces stay warm,” said Markus Espig, systems engineer, Propulsion Systems Engineering, Ford Research and Innovation Centre Europe.
The American carmaker says it’s also looking into developing other technologies that could offer energy-saving improvements in EVs, such as a heat exchanger that takes heat waste from the electric drive unit and uses it to heat the cabin and/or the battery pack, as well as a powertrain conditioning function that keeps the components of the electric drive unit at the most energy-optimal temperature.
