My experience is essentially identical to yours, including being near to dropping the first capacity bar. (Although my temperatures are even lower at present, mostly teens and twenties in recent days with lots of snow.)
Sure wish I hadn't had the P3227 update done.
I have a
2011 Leaf, with 5 capacity bars. It charges from the wall at a normal speed (does not take long, due to low battery capacity). I get about 30 miles of range.... and essentially zero regen.
Today for example: 65F going downhill
I was able to get one regen dot on a steep hill by slowing to
13 mph, then I could generally get up to about 19 mph and keep the dot going. I can feel the difference between friction and regen brakes, and yep it's turning off regen.
When regen is not working, it's the equivalent of "N" mode, and switching from D->ECO->N does nothing, thus I've also lost that characteristic of letting off the gas to slow down in traffic (it's disconcerting and probably unsafe).
- Can anyone explain the physics of WHY Nissan would do this?
- What is different with wall charging vs. regen?
- And can a dealer revert a car to older software (legally, morally or actually)?
- Would a LeafBox https://evtun.com/leafbox.html do anything?
As the battery has steadily degraded, so has the car's willingness to regen. It was a slow
frog boil, not a sudden matter.
What does Nissan have to say?
One of the LEAF’s most important features is its regenerative braking. It can add power back to the battery and enhance the LEAF’s range. It also makes e-Pedal driving even more efficient compared to a petrol or diesel equivalent. https://www.nissan.co.uk/owners/nissan-ownership/technology-explained/leaf-regenerative-braking.html
