Ross Pomeroy: The Arctic blast that chilled much of the "Lower 48" last week showcased the EV range hit to more Americans than ever, and also yielded a few more lessons. EV owners sounded off about their experiences on social media and subreddits. Here are a few of the takeaways:
1. EVs are not ready for frigid road trips. I warned about this in August: Driving an EV on the highway in extreme cold will produce a range loss of 40% or more. EV owners of various brands traveling for the holidays shared numerous stories verifying this annoying (and potentially dangerous) reality. Drivers traveling in temperatures at or around zero with a headwind could go only 100 to 150 miles before needing to stop and recharge, depending upon the car, significantly increasing travel time. When they did charge, they had to deal with another disconcerting problem with EVs and winter...
2. EV fast-chargers operate much more slowly in extreme cold, if they work at all. The colder the EV battery, the slower the rate of charge that it will accept, making "fast-charging" in subzero temperatures a potentially miserable and plodding experience. Think a 45 to 60 minute charge instead of a 25 to 35 minute one. To top it off, users reported that fast-charging equipment, particularly from Electrify America, often just didn't work in temperatures below -10 °F. Tesla's proprietary Superchargers didn't seem to have the same reliability issues. The generally sorry state of charging infrastructure shed light on another takeaway...
3. EVs driven in regions with a cold winter need to be charged at home. Preferably with a garage. Owners simply can't rely on public infrastructure in its present state with current battery technology. However, this situation could easily change in five to ten years with novel batteries that suffer less range loss and more widely available chargers, preferably housed indoor. --How did EVs handle America's arctic blast?
