I'm not sure the limit you are seeing is based on speed.
...he is reporting almost NO regen at 55 MPH.
abasile:
...Having a higher SOC (60% and higher) is definitely a factor, along with my battery being cold (four temperature bars), but for some reason the car also reduces regen at higher speeds...
Abasile is describing the LEAFs regen behavior correctly, but IMO it
may be ambient temperature dependent rather than battery temperature dependent and regen limitation
seems to be stepped rather than on a continuum with speed.
I also begin almost every daily drive with a large descent, but in colder conditions I seem to see my available regen dropping off in steps at specific speeds, ~38 and ~48m mph, IIRC, and available regen is almost negligible, above that ~48 mph speed.
So I try to use regen to slow
before I hit the steepest grades, to what I believe will be a sufficiently low speed that I will not lose regen due to excessive speed, after I accelerate even with maximum regen along the grade. This often allows me to avoid using to use the brake pedal.
I have never noticed this regen behavior
not occurring at lower SOC, as abasile reports, but my driving needs make this a very rare occurrence. I'll try to look for it next chance I get.
The only likely explanation I ever came up for this LEAF design feature was safety.
Perhaps Nissan thought thought drivers might find the driving experience of frequent loss of traction or traction control initiation on a cold and wet or icy road surface
without using the bake pedal, either unsafe or disconcerting?
But this would make no sense if this cold-weather regen limitation can be "overridden" by lower SOC, as abasile reports.
