Leaf Range in Colder Weather

Tue Feb 15, 2011 9:39 am

One reviewer's experience in colder weather: http://www.mysanantonio.com/news/articl ... php#page-1

Very consistent with the range reduction Volt drivers are seeing in different climates. On the Left Coast high 30s maybe even low 40s. In the Northeast mid 20s or even low 20s. Almost 2x. Given they hype of the "100 mile range", there may be a method to Nissan's delay in delivering cars -- cars delivered in summer will have a much better chance of reaching that range.

Despite all the criticism leveled at it, overall the EPA's estimated range of 73 miles looks accurate.

I saw this over on the GM-Volt forum and commented there, but to briefly restate what I said there, I think there are some key facts missing from the article. I calculated that, over a 24 hour course, he should have been plugged in for at least 21 hours per day. With 120 volt @ 12 amp charging, that should have provided the car with over 30 KWh of energy, more than enough for his 50 mile round-trip commute.

So either the author is failing to provide some key information or he's breaking laws of science... ;)

For that kind of temp and daily driving distance, he certainly needs a L2 EVSE to have some needed buffer. Too bad he didn't have access to it.

I read that review earlier - sounded like a bit of "hit piece".

The reason why 73 miles is not correct is that people with not predominantly freeway trips in cold weather are getting more than 80 miles. EPA rating is supposed to be an "avg" range , not some kind of 25% percentile worst range.
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

"Like a dummy, though, I decided to take the car with me to lunch, driving it about 10 miles and interrupting the daylong charge."

"Conclusion: The Leaf isn't for everyone, as Nissan Chairman and CEO Carlos Ghosn already had told me during an interview a few months earlier. And it's certainly not the car for me,"

The REAL conclusion: the Leaf isn't for stupid people, of which I admittedly am.

What an idiot. :evil:

i believe the article. i charge at 110 volts and it is slow and will not recharge overnight for what he is doing and it wont work for him because he does not want it to work for him.

he is right, the heat is a poor design and could have been better. the Prius plug in will use a heat exchange system reputed to be more efficient...but then again, not sure that the Leaf has the same "heat" supply to work with. with the heat running, its easy to lose 15 miles of range since it can draw more than 4½ KWH. in a RT 60 minute commute, that is about 15018 miles of range dedicated to heat.

drive 70 mph, that is an increase of....18% more power to move the car than driving 60 mph. that is another 15-18 miles of range. so he would be running 80+% of the pack daily without the lunch runs.

with the lunch runs of "10 miles" i suspect that might be a one way trip and a trip he would not normally make simply because its something you would not have time for on a daily basis even with an hour.

so ya, i can believe him. believe that he does not want to make EVs work for him and that is ok. right now, the supply is tight and he can go ahead and get out of the line.

I'm voting idiot:
Here's the real scoop: By the time I got to the interstate highway that leads to my downtown office — the entrance ramp is about 2.5 miles from my house — the miles-to-empty readout had dropped from 100 to 81, indicating that I already had used 19 miles of the battery's power.
He hadn't used 19 miles of battery power - it had just adjusted the range estimate to his driving style. How can an automotive journalist not understand that?

It's like saying, in an ICE car with a mpg meter, that if you drive it hard and fast and the mpg drops from 50 to 30 that the engine had been damaged.

The point which is being missed is that he consistently got half the range being projected by the Leaf. The 100 miles was more like 50 miles. 66 miles was more like 33 miles. That was consistent in every scenario he lays out.

I was surprised at this until I read about the snow, at which point I realized he had the car during SuperBowl week when it was unseasonably cold in Texas, though those temperatures would be expected in many part of the country. The main takeaway is that the Leaf's range in cold weather will be more like 50 miles rather than 100 miles. Another takeaways is that the EPA range of 73 miles is going to be accurate, assuming of course that Nissan ultimately sells the cars in cold weather states.

You can call the guy an idiot all you like but the only real mistake he made was in believing the car's range estimates.

No. He isn't even charging to full. Anyway, it is a confusing hit piece, he doesn't give all the details. Ofcourse, being a Volt fan you would like it ;)
