Cold Weather Impact

Someone had asked about cold weather impact. It's only -19F right now, so this initial post just confirms what I have already experienced in these temps so far this winter. The temp has been dropping all day, it is forecasted to bottom out at -37F tonight, so that will be the real test.

In the garage (heated ~62F) the GOM gave me 166 miles, which is what I see every day. A few weeks ago 177 miles was normal, but the temps have been near zero or below for the past few weeks, so I am now at ~166 miles. The car was plugged in, but it was 'preconditioned' before I left because I left an hour earlier than I had planned.

Outside temp was -13F. I drove 2 miles (with a quick stop at 1.2 miles at the gas station to grab a Dr. Pepper), and 10 minutes later, the car still showed 100%, but now the GOM gave me 112 miles. It should be noted I have found the car does not adjust it thermometer to temperature changes very quickly. In the garage the car registered 61F; at the completion of my journey (~10 minutes) it was registering -9F, although the actual outdoor temp was -13F. I have never had a car this slow to adjust before.

I plugged the car in with the stock EVSE and checked on it about an hour later. I had not cancelled my previously scheduled preconditioning, so 3 minutes after my set departure time the car showed that it was charging, with the battery at 97% and the GOM at 110 miles and it was adding 0% charge per hour...

I checked again 2 hours later and it was now showing 100% with 109 miles, still charging at 0%.

I set a new departure time for Noon and at 1139 it showed charging at 0%, current level 93% with 105 miles of range.

I ended up not leaving and here it is at 1215, charging at 1%/hr, current level 96% with 100 miles of range.

I can add the pictures if anyone cares. But so far it is exactly as I would expect.

I will see what it does tomorrow. I might leave it outside without plugging it in just for fun.

I honestly wouldn't leave it outside not plugged in if it gets very cold. It will be fine, but it will use the charge to maintain battery temperature to prevent any damage. Tomorrow night I plan to make sure all my battery cars are in heated garage nicely tucked away....

Many thanks, very interesting. Do you attribute your typical ~177 mile range to cooler winter temps as well (or mix of driving style, etc.); whereas folks in warmer climes are seeing 200+?


Is part of the take-away here also that the I-Pace remains suitable for some daily / local commuting even in extreme cold (while EVs with less capacity might be knocked out)?

But my poor little Smart TwoFour doesn’t want to be alone outside in the cold. Besides, now that I have a high priced city car, the Smart is my highway car so I should be nice to it😁

I would call that some proper extreme cold! Where do you live?

Yes, I’m sure it is the temps. My overall driving ‘style’ is rated at 97% on the car, so there isn’t much I can do to get better fuel efficiency. The consumption has been very consistent in the 3600 miles I’ve driven the car and goes up and down with the temp.


“Is part of the take-away here also that the I-Pace remains suitable for some daily / local commuting even in extreme cold (while EVs with less capacity might be knocked out)?”

Suitability is an individual decision. I imagine anyone could make anything work, but it would be dependent on how hard they want to try.

I personally really like the convenience of an ICE vehicle that I know can go 200 miles even when it is super cold, it only takes a couple minutes to add another 200 miles and you can do it without worry because gas stations are plentiful! 😁

I’m learning to live with the short-comings of a BEV, but I still don’t like them!😉

I would be very careful with leaving that thing outside and unplugged for extended periods of time in such cold climates. EVs are great, but they are more made for the California winters, not the Minnesota ones. Glad you have a heated garage

I normally do not plug it in when it is outside, I do it today just to see how it behaved. I would like to see if there is much difference when I go from -20F to -37F. I do not think it will change much

In Denver today it was about 25-30 F when I took the car out.

I drove up to the Genessee area which was probably a good 1k-1500 in elevation change.

I started the day with 100% charge and 217 miles on the GOM. I drove a total of 30 miles and now show 151.

The whole way up it was still showing around 200. When I went in to show the first home and came out 10 minutes later it had dropped to 155 miles of range.

I also show I used 19% of the charge.
