A little background:
I previously owned an MX90D which I had for 2 winters in Montana, so I’m no stranger to cold weather and the issues it causes. My MX would sit in a heated garage (45-50F) overnight. When I’d head to work which is 35 miles, mostly interstate, the battery would start out with about half of the regen limited. After about 20 miles, the battery would be warm enough that I wouldn’t have any regen limit. Typical MT winter day is in the teens. After sitting at work for 8 hours in below freezing temps the battery would be limited to about 1/3 regen, it would be fully warmed up with no regen limiting by the time I arrived home. Even in below zero weather, the battey would warm up to the point I would have little if any regen limiting during this trip which I would do pretty much every day.
Now my ‘18 MS100D:
In recent weather with the temps in the 40’s - 50’s, my battery would be about 1/2 limited and stay that way for the entire trip. Consistently. Today, it was in the teens, left my garage about 1/2 limited, drove 15 miles and parked for 7 hours with temps in the low 20’s, and full sunshine. When I got in the car at 3pm the battery was completely regen limited, offering no regen whatsoever. After driving for 20 minutes, I had a sliver of regen available, probably about 1/20th of full regen.
Basically, the only time in the last month or so in MT that I have had full regen was immediately after taking it off of the charger, as I drive the battery will actually cool down and start limiting the regen. During a 150mile trip in the 40’s I went from full regen to 1/2 regen while driving.
Range mode off. Heater in the car seems to work well. Driving typical highway speeds of 75mph mixed with some city. Exact same roads I drove for 2 years in my MX.
During the previous 2 years, I NEVER had my MX fully limit regen, even sitting for a full day in below zero weather. I’m assuming there is something wrong with my battery heater, or else V.9 of the software has drastically changed it’s operation.
Anybody else experience something similar now that the temps are dropping? At this rate I will need new brake pads by spring since I basically have no regen braking whatsoever in winter temps.
