I had to give up on 80% a long time ago. That is at 100% charge.


That is really odd, I have done over 60 miles on a single charge and it was much colder than that.


I do have 3 bars of capacity loss, that's why is so low now. I am on my way to loose my fourth.

Re: Winter is hard on range!

Winter is underway in Minneapolis. Since Thursday morning we have around or below zero (F). This morning it was -7F. Observations -

1. Pre-warming the car even with it plugged in cost me 2%. I think the climate control is taking more than the charger can deliver? I should be able to avoid this lost by proper use of the timer.

2. Any trip, no matter how short, will have a big impact on range. I didn't bring a lunch to work today so I ran out for a bite. The 4 mile trip took almost 10%...most of which went to keeping the windows clear and warming the cabin. It had warmed to about 2F at lunchtime.

3. The Leaf handles very well with snow and icy roads. Traction control kicks in at the appropriate time and works as it should. This was with the original tires.

4. Heated seats and steering wheel really help, but I'm not a huge fan of the cycling they go through. They also seem slow to warm in extreme cold like this morning.

5. Based on one data point from yesterday, the range dropped about 40% from my summer range. This was with the climate control set at 60F (the lowest setting...wish we could set it lower). This was with slow driving as traffic was backed up yesterday...lot's of time spent at 10mph or slower. In this case this probably cost me range as I was running the heater and defrost for a good portion of the time.

6. Looks like we will be in a cold to very cold pattern for a couple of weeks....good chance to learn more and to figure out how to optimize cold weather range. Outside of a couple of days where it is suppose to sneak into double digits it looks like we will be just oscillating between single digits above and below zero.

7. At lot of you guys do not know what 'cold' means :)

Maybe by the time that 4th bar goes away, Nissan will have the new hot battery in production.

I get 60Km with 0 % to spare at -30c (-22F) that using no heat in the car, just the steering wheel and seat heater with a blanket for the rest of me, pluss my winter coat/skie mask/gloves and thats the warm weather here! when the liquid nitrogen starts pooling about it gets annoying as your boots freeze up! all so about the same time most us canadians consider closing the windows at night!
2013 SV Leaf, Level 2 charger, so far all works great! 130Km daily, 100% charge at night on 240 then trickle charge for 8H durring the day on 120v.

Level 2 charge starts at 130am environmental starts at 6am to 25c for a toasty warm defrosted car!

That's a simply ferocious temperature to force any batteries to operate at. Is the reduced range down to a heavily reduced operating range allowed for the battery, in an attempt to avoid degrading battery life, I wonder?

The advantages of EVs would, I think, begin to be very questionable if a significant fraction of your year was spent at these temperatures. Certainly the 'frontier spirit' though!?

My Leaf does great on cold weater ;) . At 35000 miles I drove 12 miles in 20F temperature and only lost one bar and grew one tree.

Now some more info: car was preheated and for the drive the heat was disabled, I had 50 mph gust from behind and drove 40-45mph. The return trip 12 hours later started at 11 bars and ended at 6 bars, against the same wind, heat at full blast and doing 60-70 mph.

I hope so, a heat resistant battery would be wonderful. I own the car and did not lease (unfortunately - had I known what I do now I would have leased or waited). I currently have 49k on the car.

Thanks for this data point. -22F is about as cold as it will get here, so it is good to know what to expect before running climate control.

We've had about a week now where it has been between -10 and 5F....I've gotten in some good learning. Mostly I wish I could set the climate control lower than 60F.

yesterday was the least efficient day I have ever seen. I only got 3.1 miles per kilowatt hour. I only drove about 20 miles as my charge went from 85 percent to 45 percent. It was one of those days when the temperature was right at freezing and the humidity was high. I had to run the heater. It was just too cold. And that was all at speeds less than 30 mph!

This evening I got my second LBW ever. I started with less charge than I thought I had, went to two cities in my area, then about 5 miles from home got the warning. I got back about one mile's range on a down hill, then ran an errand in town and arrived home with 16% SOC. The heater really lowers range when in constant use - even the heat pump. I was never worried about not making it, or about getting Turtle Mode, though.
