*'estimated range' is the range I would be able to drive with 100% off the battery, while driving an average calculated speed.
This range is estimated based on each ride that I do. Looking at the used SOC %, ODO meter and start and end times of the ride. So, when I wait for a traffic light, it will affect this range.
This method is not used to create hard core correct values; but it does give an indication on average (after 60 km/h )

Thanks Victor, but I do not use Python.
I extract data from my logs using a modified version of https://home.hasslers.net/zerologparser/zero-log-plot.xls
But I have to mix data from MBB, BMS0 and BMS1 files, and they have different time clocks. So I have to synchronize all that.

Update - a friend at Zero reached out to me having read this and wished to express they are under the impression that there is at least *some* coulomb counting as a small part of a complex algorithm. This is why, in their words, "the SOC changes even if there is no current, the other portions of the algorithm are affecting the SOC calculation"

So I may have misspoke.

Could you please ask your friend if there is any way possible to calibrate the SOC?

Here's what they said:

It continually calibrates, it doesn't reset with a full discharge/charge. There is a serial comment to reset the calibration but generally that is only used when installing new firmware that has new SOC algorithm and will calculate calibration differently.

They confirmed dropping to 0% and charging does nothing.

You and I could both fully charge and balance our batteries, start out on a trip at 100 SOC.
When i start out the temperature outside is 86 degrees.
When you start out the temperature outside is 46 degrees.

We both accelerate to 45 mph and put our bikes on cruise control, lets assume we are in the desert and it's just a long ass straight road, no up and down with speed elevation or turns to deal with.  Lets also assume both our bikes are identical and we both weigh the same and drive the same, ok you text while you drive, I'll watch the road

Let's ride for 100 miles.
At the end YOUR SOC is going to be quite a bit different than mine.

Who's is wrong??

Still don't understand why people want to run with this, measure with a micrometer, mark with chalk, and cut with an axe mentality and expect micron presision.

Oh, and by the way.  let's say your SOC was now 20 percent at 46 degrees after your ride.  You decide to call it a night after your long arduous night of riding and sleep till noon.  the temperature is now 88 degrees out and the sun's been beating down on your bike for a while now.  Your SOC just went from 20 percent to 28 percent when you turn your bike back on but you did not have it on a charger.
Hmm, something must be broke,....... this CAN'T be accurate !!
Quick, get the elastic tape measure,  body fat percentages are NEEDED NOW  !!!!
