Preheating is not an absolute necessity for charging. It is done because it helps the charge go faster.

- _ea1k 3y agoTrue, but in an extreme case, the battery may not take a charge at all without being warmed up. This may take 30+ minutes if it is extremely cold soaked.
- natch 3y agoIf we’re going to extreme cases, even worse, the battery won’t work at all if you disconnect it or grind it into small bits. Or, you could take care of your car as recommended and if a battery preheat will help, use scheduled departure features and plug it in if needed and possible.
- _ea1k 3y agoI can see what you are getting that there. The problem is that Chicago actually caused a pretty extreme case, mostly due to infrastructure issues. Cars waiting in line for hours at low states of charge effectively couldn't precondition. I've never seen this scenario happen in the real world, but I guess we've found one weird edge case where it can happen.
