Speaking of comfort, why even wait to start your BEV to warm it up? If you charge at home, just tell it when you plan to leave and let it preheat the cabin for you, all while still plugged into the charger. Indeed, Cadillac's version seems the most elaborate to capture any wasted heat, but many manufacturers offer some kind of heat pump to serve a similar purpose. "Because we have some bandwidth there, we like to call it an advanced heat pump system," Cansiani says. That can then transfer any excess heat from one place to where it's needed. Kevin Cansiani, lead development engineer of the Cadillac Lyriq, says it has something called the Ultium energy recovery system, which connects the battery, drive units, power electronics, and cabin to a heat pump and coolant system. AdvertisementĪnd engineers continually work to utilize any waste heat available to warm the cabin and limit battery pack usage. Ten minutes of shivering as you wait for the engine to warm up is a thing of the ICE past. As a result, you get separate electric heating elements that start working as soon as you start your car, heating either your seat or the whole cabin, or both. Because electric motors operate so much more efficiently, there's a lot less waste heat to use to warm the cabin. ![]() Moreover, most of the complex parts in a car that require viscous fluids do not exist in a BEV, i.e., no engine or transmission to worry about.įurthermore, the very thing that creates the range disadvantage for BEVs also delivers a distinct advantage. Thanks to smaller grille openings and flatter underbodies (no driveshafts or tailpipes to worry about) BEV bodies tend to have lower drag coefficients and slip through the air with less effort. And that means your engine, transmission, and differential all have more work to do-requiring more energy-in the cold. And all the viscous fluids vehicles need take more time to warm up to their respective operating temperatures. Air gets denser as it cools, which takes more work to push through. ![]() And, generally speaking, it takes more energy to warm an electric vehicle in the winter than to cool it in the summer.īut bear in mind, all cars lose range in the winter. The two main reasons for that stem from the need to keep both the cabin and battery pack warm, which requires energy that would otherwise go toward moving. ![]() It's true that BEVs lose range in colder climates. Let me explain.įirst, actually, let me concede a point. Comfort, control, even durability benefits come along for the cold ride. Objectively speaking, a battery-electric vehicle provides a superior driving experience in cold and inclement weather to its internal combustion engine-powered counterparts-for numerous reasons.
