[Ovmsdev] Seeking ideas for 'range' representation

[Mark Webb-Johnson]

Felix,

Yes, I agree. This is really not something that can ever be 100% - we just want something to represent roughly what is possible and to limit the charge stations that we show.

A nice thing about circles is that it easy to visually estimate 50% (or whatever), so I think the user can do this themselves.

Perhaps the existing outer estimated-to-ideal circle at 50% transparency, then an inner estimated-to-N%estimated circle at 25% transparency? Or is that too complex?

We're also planning to have a feature of show-route-to-charging-station, for a particular selected charging station, and that will be google maps / whatever so will show real distance by road.

Regards, Mark.

I think the range estimate would have to be only a percentage of the two values so that the range circle would be more realistic….. Maybe 60% of the values given by the car or something to that effect.  Otherwise you will never make it to the next charge point………. what do you think?

Plugging in the values for my car today, assuming I was somewhere in the centre of the UK, it would look something like this:
