Electric vehicles are becoming increasingly popular, but one of their biggest enemies is low temperatures. Cold weather can cause range losses due to the energy needed to keep the cabin warm, and traditional air conditioning systems can be inefficient. However, Ford has been researching a new way to heat the interior of electric vehicles that could lead to an increase in range of up to five percent in temperatures as low as -7℃ (19.4 ℉).
Ford conducted a study in Europe, fitting a fleet of electric Transit vans with heated elements on the armrests, floor mats, door panels, sun visors, and a panel below the steering wheel. The vans were used for parcel deliveries, special goods deliveries, and a craftsman’s one-day job 350 kilometers (217 miles) away. The results showed that the heated elements used 13 percent less energy than the aircon would have used, leading to an average range gain of five percent.
The study also found that frequent door openings and closings lowered the temperature of the cabin quickly, making the heated elements even more efficient. Ford engineer Markus Espig said, “Reducing energy use not only improves range, it also cuts costs and helps ensure that the way we travel is more sustainable.”
Ford is also looking into 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.
Low temperatures can be a major issue for electric vehicles, but Ford’s research shows that there may be ways to reduce range losses and increase efficiency. With further development of these technologies, electric vehicles could become even more viable for everyday use.
