I think that is much easier said that done. You might have to rewrite firmware inside some different dashboard controller.DougMarker wrote:1. Instead of a box make the SOC percentage replace the useless miles remaining guess on the dash.
Allow manual input of a "miles per XXX" figure; combine it with the current "SoC" figure to optionally display "remaining miles". It'd be up to the user to acquire her own "miles per XXX" figure: by guesswork, or by using historical data, by using the car's "miles per kWh" figure(s), etc.garygid wrote:SOC-Meter Improvement Suggestions Summary:
You're quite right.garygid wrote:Before that simple "calculator" (one multiply) function would be meaningful,
a MUCH BETTER indication of the remaining usable energy is needed.
You put in 4.3 mi/kWh, and the "guesSOC" value is 10% (28 raw).
Does that dependably mean that there is 2.1 kWh usable energy left?
So, doing the multiply of 2.1 x 4.3 = 9.03 ...
or even just mental math of 2 x 4 = 8-something ...
can be VERY misleading if only 1.2 usable kWh remains!!!
But I keep seeing people posting the CAN bus SoC number along with a percentage. Does the percentage number also come off of the CAN bus or is it calculated as a percentage of 281 (in which case it's not very useful since the number is not linear)? (Sorry if this has been discussed already; I have not been following the "SoC meter" threads very closely.)garygid wrote:No, it appears that the "SOC" number is not linear, or even dependable, especially at the low end.
