This is super cold and a far-from-low charge. Yeah, you got an expected charge rate. Get it down to 10% and you'll do better. In 39F weather, your battery is going to never really get up to temp unless its driven straight from a heated garage, in which case it should be at 100% already.that makes sense thank you! Yes today was about 39 degrees F. But - I had been driving the car for about 45 minutes before starting the charge. Wouldn’t that have warmed the battery some?
and are the charging speeds you described (100 kw below 35% and 80kw from 35-80%) theoretical or realistic to expect in real life?
