I wonder why the code is so conservative?</div><div><br></div><div>The current logic is, indeed, to use SOC% to calculate the ideal and estimated ranges.</div><div><br></div><div>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.</div><div><br></div><div>Regards, Mark.</div><div><br><div><div>On 22 Jan, 2014, at 9:36 am, Paul Churchley <<a href="mailto:paul@churchley.org">paul@churchley.org</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">In my experience the range from 100% in ideal conditions rarely exceeds 50 miles.

<div><br></div><div>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.</div>
<div><br></div><div>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.</div>
