Thank you for your great videos and your testing! I believe range is calculated with consumption on the last kilometers or minutes if a drive (VW top secret how much km and minutes), but after some hours it switches to the calculation by standard value. My home is up a hill, so I see range 40km at arrival, and 55km on next day without charging. Would explain bernard dumel sees no change, if he just arrived few minutes ago.
On my Citigo iV I’ve wondered about the formula for the estimation ever since getting an unrealistic 371 km range estimate at 95 % capacity. That “Cruising range standard consumption of electrical operation” parameter is of course just a term in the full formula, because the range shown for the 3 values would imply 3 different battery capacities from 25 kWh to 50 kWh (and we know that factors like outside/battery temperature, recent driving conditions, and using air-conditioning/heating also affect the guess). I’d say that more datapoints are needed, e.g. trying parameter values from 8 to 20, and also noting down the exact values of the other dependent factors (e.g. a digital battery state of charge measurement instead of estimating it based on the analog charging indicator in the instrument cluster). Otherwise, based on the 3 tried values (8.0 → 395; 10.4 → 303; 11.0 → 287), the formula seems to be a very inaccurate Range = 3.8889 × Consumption ² - 109.89 × Consumption + 1025.2 or even Range = 3194.8 × Consumption ^ -1.005 That range estimate is really important as the traction battery depletes, because the warnings and Eco+ and Turtle modes come on depending on remaining range and not remaining capacity, right?
range prediction on last % SoC is very unreliable, if you never trained the computer before. On my first time below 50km, suddenly turtle came on! Prediction was wrong by many km! Then I tried again few times, it was more accurate then. one time I could drive another 15km with turtle on - drive slow, flat road. So use down to 0% from time to time will make prediction accurate
I tried it today with OBDeleven on 2020 e-up. The original value was 10,4 and I could change it, but no change in car display. Always same km range. I tried it 30 hours after last drive, so assume it should no longer use the last consumption for calculating range estimate. Weird formula behind it...or fuzzy logic :-)

is this number going to change automatically? bcs i see that range is changing depending on the short term average
I think this is some correction factor that is used in the formula used for estimating the range.
It's possible to know the total energy-charged?
Yes I remember I have fouls the total kW statistics somewhere in the OBDELEVEN menu

interesting
is this for example 11 kWh a permanent change of range calculation cause usually it is estimated based on average of last 50 km ?
I can not say for sure. I think this is some correction factor that is used in the formula used for estimating the range.
Hello don't work for my car E-UP 2020
What exactly doesn't work? It does not change the estimates or ... ?
@@tedonash2681 Yes don't change the estimated Kms
@@bernarddumel9064 interesting. I will ask others just to confirm if this is something in your car or it is global
Tedo Nash Hi, the same for my e-up, 2020, do not change the calculation of the range km
@@rolandschreiner4035 ok I will try to find where the problem sits. I will check several times on my car to see if I find some pattern.
