Quote from: David Majoy on May 07, 2023, 21:48:40Recurring question as a Canadian is: what is the cold weather performance of the various batteries? Example; commuting 60 kms with temps -30c; car parked outside with temp rising to -20c and return commute of 60kms in -25c. Night parked unheated, so the battery might spend weeks on end being very chilled. The problem is spooking many people needing a reliable way of ruling out the problematic battery cars in winter conditions.
Over 90% of new cars sold in Norway are EVs, some places get so cold diesel freezes but EVs work fine.
Weeks on end being chilled isn't a problem unless it is almost empty, unlike lead acid batteries lithium ion isn't going to die in the cold. Though you may not get accurate readings from the battery until it is warmed up, and you should preheat the battery first before driving off because regen won't work until battery warms up. Otherwise, no issue.
Though usually very cold places have places to plug in for cars anyways, that is because your gas car won't start or can get damaged. So they have engine block heaters. If there is a place to plug in a block heater, you can plug in the ev as well.
