I’ve had my '21 Chevy Bolt EV through two Nebraska winters so far where I park at work overnight without a plug for charging. I typically see a charge drop of 1% when the temperature is below ~ 20°F (-7°C) and maybe 2-3% when it’s below 0°F (-18°C). My status screen will show that a few percent of my battery capacity has been used for battery conditioning.
I’ve never been overnight in sub-zero temperatures for more than 8-9 hours without plugging in and it’s never been a problem, no matter how cold it’s gotten.
