The BMS went from about 81.0 kWh to 77.0 kWh in a short period.
The 100-0% drive ended up with 100-0.41%(was 0.27% when I parked the car but the BMS readjusted the SOC shortly after).
513 km driven and 75.15 kwh used. Remaining energy /Nominal remaining 3.80kWh (buffer 3.5 + 0.3kWh from the 0.41% SOC). The sum of energy was 78.95 kWh.
(This drive was done in two parts, because of a job that had to be done in between, drove 235km, parked the car for about 8hrs and then drove the rest. I did drive 90-100kph on the first part/235km to ensure I had energy to go all the way home. When driving home I used the nav plus the AP, ended up at 86kph with a slight headwind to get home with a safe margin which I then drove around my city to drive to 0%.)
I did have a 100-0% drive planned since x-mas as the BMS was overestimating, and I would like to see the real capacity. In the perfect world we would want the drive to be only one long drive, but my two part divided drive only cause a slight loss during the day. I know my car does use like 0.5-1% during a whole week so I do not think it actually would have made a noticable difference.
I havent had the time to do a one long drive yet, so I took the chance when I anyway had to go to work over one day.
As a parentesis, the 79kWh capacity is exactly within my own calculation, that is built on average SOC, Average batt temp and time + my number of cycles, dept of cycles etc.
There is only one car with teslafi and the same mileage. My car has the longest range of these two. (I of course do not know about other cars over/underestimates, it sure looks like the software change that seem to have ”taken my range” also have increased other cars ranges.
Its probable that the average will even out on the green line when there is more cars with data at these points. Still I guess there will be a increas from what I hear from people with the same car = increasing range after that update.) Picture below from right now, NFP 77.5kWh but the real capacity is 1.5KWh above, so that should be about 10km more range.
