Recovering range after two cold nights?

[changelives]

Hi,

I live in Southern California and I have been getting a solid 290 to 300 miles for a full charge. A few days ago, I went to the mountains for two nights and the temperature dropped to the 30's overnight. When I got there, I had a 70% charge and 220 miles of range. After one nigh in the cold, still with 70% charge, the range went down to 70 miles and I was getting constant "Critical Alerts' that my range is dangerously low and I need to charge right away - at 70%.

I came me down the mountain yesterday back into warm weather and charged to to 85% - a the range showed 140 miles. Today, with 65% is shows 110 miles.

Is this something that will correct itself, or could going to the cold for two days have screwed up my battery somehow?

Thanks

It will correct itself. Climbing the mountain would be hard on your range and it is using that burn rate at the moment in its calculation to make the best guess. I'd say that is a bigger factor than the cold. You should get your normal range with your normal driving regardless of what the GOM says.

Coming from my end here in North Eastern Ontario Canada what you think is cold is nothing I have a Mach e also I had no issue in -28 degree weather this far for two night try a week and I still drive 40 miles back and to work no issue my range in km showed a little less then optimum at 240km but that still decent once on the highway we get going no issue my extended range should get me close to 400km or 320miles there about should be good once it heats up a little

Your range didn’t go anywhere. You can drive just as far in the warmer weather this week as you could last week. The computer trying to predict your driving habits just doesn’t know what you’re going to do because you broke the pattern. The number on the dash is a guess based on your recent drive. It isn’t a real, “you’re only able to go 160 miles.”

I think you need to read Guess-o-Meter 101:

Range alerts are based on estimated mileage remaining, not battery percentage.

Sounds like somebody may have snuck out and swapped the wrong battery into your car while you slept.

Southern California wonders if 30 degree weather will break their car.

Minnesota says “hold my beer.” ?

I’m slowly getting my brain to use SOC instead of range. The range will will come back but the best explanation I’ve heard for why EVs lose so much in inclement conditions is they are vastly more efficient delivering energy to the wheels so when extra is required for something else, you are using up your stored energy. Funnier is what happens to the range on a Lightening when you plug in a trailer. ?

Nope. Two nights in cold weather has ruined your battery. I'll buy your Mach E off you really cheap so you can buy a fresh one.

and estimated mileage remaining is based on battery %SOC and recent efficiency
