Battery Degradation

[Mustangor]

Our F150 Hybrid Distance to empty is often way lower even after refueling as our driving patterns are erratic. So instead of 600 Miles to empty when the tank is full, it will show 443 Miles upon startup and then stay at that number for 50 or 60 miles and not drop mile for mile with the odometer if were driving slow and constant. It's just as frustrating ias our MachE if Inlet it gets to me. Mentally I just ignore DTE and look at the fuel Gauge. Same for the MachE, we just watch the battery "gauge". FWIW.

Yeah, same here, but the whole point is to see if the battery degradation is real or not. When the vehicle was brand new, battery fully charged, UI indicated always an estimated range above 420km whatever the conditions where - driving, climate, temp, etc. The HVBSoH reported by Torque Pro was 99%. Then, after 6000km, it went down to 91% and I never got an estimated range above 400km since. I understand this "estimated range" is not very reliable, but I use my car every day on the same trip and my overall feeling is that range is now lower. I have to charge it more often, for example. It's not a massive decrease, and it could be a bias because I see a battery degradation. I just want to be sure. Range decreased from 430 to 380km is not a big deal, but it's better to know the true range before planning a long trip.

Try doing a battery calibration first, that will probably bring the capacity estimate up some: https://www.macheforum.com/site/threads/hv-battery-calibration-procedure.23815/

You didn't do the rest period, that's important. Don't charge it immediately, let it sit at 5% for a number of hours first. Not sure the calibration will work since you skipped that.

After doing the battery calibration, including rest periods with empty and full battery, here are the numbers at 100% :
Estimated range : 400km
Capacity : 64 kW/h (reported by Torque Pro with OBD dongle)
HVBSoH : 91,5% (no change)

Looks to me like my Battery pack really lost 8% of capacity after 6000km for no reason.
