Paul, Wow. 50 miles ideal vs 35km in the code is quite a difference. I wonder why the code is so conservative? The current logic is, indeed, to use SOC% to calculate the ideal and estimated ranges. Setting defaults for ideal to X and estimated to Y, per 100% SOC, seems sensible. It is possible to use 'features' to store these - those are 8bit integers and there are a few available for such uses. Regards, Mark.

In my experience the range from 100% in ideal conditions rarely exceeds 50 miles. It does occasionally and many have done well over that but for the vast majority, for the vast majority of the time, an ideal conditions range is 50 miles.
We have the SOC% so can we not simply use that to adjust the ideal range?
My normal range varies from about 45 miles to about 30 miles depending on temp, speed etc so can we just adjust the ideal range by say, 4/5 to give typical range?
I realise that these are not scientific ways to estimate range but perhaps that is about as good as we can expect for now? We can adjust these multipliers once we have had a chance to test it out.
Could we use parameters to set a personal 100% ideal range and 100% typical range? The module could then provide a personal range based on our personal parameters and as we get better (or worse!) as EV driving so we could then adjust our personal preferences and tune our own personal range.

Seems to be a hard-coded constant:
va_drive_distance_bat_max = MiFromKm(35); // initial Battery distance in km
I think we could be a bit 'smarter' with this - particularly given the 'ideal' and 'estimated' range indicators we have.
Any ideas?
Regards, Mark.

That's odd because i've just noticed that in the past few days - the range now being displayed on my Volt, which used to be as you described, is now quite acurate?

Just a bit of feedback regarding the range displayed on the phone app for the Ampera.
A full charge currently displays a range of about 22 miles. This is probably a bit over half the real range and well below the estimated range on the car dash.
