[Ovmsdev] Ampera Range

[Paul Churchley]

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.
