My OBD adapter doesn't appear to be working, so I haven't checked. LEAF Spy is great, but we haven't found it necessary for routine driving.
However, I agree that it makes no sense to blame the motor temperature for bad regen. Particularly if I've only been driving for ten minutes and the ambient air temperature is about 45 F.
I can understand regen limitations when the battery is cold, but as long as it's possible to charge the car on L2, there should be at least some regen. Plus it should be possible to offset the heater consumption.
Might want to log a drive down the hill. At first my reaction was that the tech's comments made no sense but after thinking about it.... well, maybe.
LEAF Spy added motor temps to its logs and on DC fast charging, the motor temp doesn't change at all which makes sense since its bypassing inverter/motor directly to battery.
While driving, temps get pretty hot pretty fast. So the big question becomes
1) Has anyone seen reduced power going up large hills? The power out greatly exceeds power in so maintaining a power output over 30 KW would be easy to do even on very moderate uphill climbs.
2) How hot is your motor getting per LEAF Spy on your regen trips down the hill? Is there a cutoff that occurs initiated by a certain temperature? I dk off the top of my head, but iirc correctly the high end I generally see is around 125º maybe low 130's? and never had a reduced power issue that I remember.
I don't generally do anything near what you do but I have a decent slope on Highway 18 westbound. Its very steep in places but less than 10 miles but I have powered up that hill with all power circles lit up several times. (One of the joys of EV driving. Hill climbing! ) during all kinds of weather but its still as much as 15 mins (sometimes MUCH longer) of sustained high power driving.
Finally; on that "cold issue?" How cold is it cause I hear about it all the time but I have never seen it affect the power output of my car and my LEAF did see low teens a few times.
