Better battery range?

Thu May 02, 2019 11:26 am

2018 SL here.
I have been driving to a particular destination 3 times per week, and each time I use 13% of the battery each way. 26% round trip.
Recently, I have now been using only 10% each way. 20% round trip.
I know we drive differently, but I really have kept it pretty constant. I use cruise control and the e-pedal on the trip.
Is it possible that as the battery life wears in, I could be getting better battery range?

Maybe, but I would bet on a higher battery temperature being the cause. I assume a cold battery can hold fewer Ah's than one at 'normal' temps and if the SOC reading relied on this it would act as described.

The other possibility is that you are becoming a better Leaf driver.

Also hotter air is less dense, and air resistance is the primary energy consumer at road speeds.
I noticed you're still working with polymers.

All good points......maybe I am becoming a better Leaf driver, I do use the e-pedal more now.
Perhaps it is the temperature, things warming up here.

It's all of them. Even as my 2013 was starting to lose range the first couple of years, I was still driving farther with less effort, as I learned the ins and out of driving a BEV.

I agree it's everything mentioned. But my guess is that it's primarily the transition from winter to spring (i.e. warmer temperatures) , which results in more miles/kWh.

I have pretty consistent usage, back and forth to work. On a monthly basis I record my miles/kWh, and I see a pretty significant change as the seasons change:

Jul - 7.2
Aug - 7.1
Sep - 6.9
Oct - 6.5
Nov - 5.6
Dec - 5.1
Jan - 4.9
Feb - 5.1
Mar - 5.5
Apr - 6.3

What car do you drive? I average like 3.8 (no heat/AC) in my Leaf during the warmer weather. Clearly, I'm doing something wrong. (Or I'm having too much fun!)

Even driving conservatively, I can't break 5.2 or so.

I averaged about 3.8 in my old Leaf as well. 4.2 tops. Now it's more like 3.6 to 5.5.

Too much fun, or too high of speed.

I usually get 3.x in the winter, and 4.x in the summer. I've driven for range a few times, and you would like to:

1) 2 bubbles of acceleration maximum
2) keep it under 35MPH. Maybe under 30MPH
.
3) neutral throttle as much as you can.
4) Regenerate if you need to sop
5) Friction braking as little as possible.
6) Flat or very gently sloping roads.
7) 44 psi tires.

I've gotten 7 mkWh for a trip. Averaging 7.1 for a month? I couldn't do that. Too many hills most of the places I go.
