Electric Cars and Cold Weather

Jack Stewart at Wired:

Cold temperatures can hurt both [how far EVs can go, and how long it will take them to recharge], especially when it gets as severe as Winter Storm Jaden, which has triggered states of emergency across the country and will subject more than 70 percent of the US population to sub-zero temperatures over the next few days. That's because the lithium-ion batteries that power EVs (as well as cellphones and laptops) are very temperature sensitive.

It’ll be interesting to see how society transitions away defrosting ice and snow off of their gas car before work in the morning, to making sure their electric car is plugged-in and “defrosting” the battery before work. Then again, perhaps cold batteries won’t even be an issue by the time electric take hold of the greater vehicle market.

Jack concludes the article:

In the longer term, scientists are working on solid state batteries, that don’t have liquid inside and won’t be so sensitive. But they’re still at the lab stage, so figure five to 10 years before you get to see one in your garage.

Technology is ever-progressing toward solid state designs, and batteries are no exception. While the early adopters of electric cars may witness the transition from liquid to solid state batteries in 5 to 10 years, I’m skeptical that electric cars will takeover the majority of the personal vehicle market within even 10-15 years. By the time electric cars become the societal norm, cold liquid batteries may no longer be a concern.
