I don't know of one, but it sounds like something that could make use of the route-planning ability of Osmand with extra steps...
Maybe... I never used it before, but maybe eyeballing the distance by direct line is close enough for planning? I am not sure... Either way it is cumbersome....
sorry I was talking imprecisely; I meant "extra steps" in the code, rather than as a practical workflow to follow.
For now I just use ABRP. It may be different for you, but I find that most journeys I do I only really need consider a subset of chargers - we are aiming to stop approximately every 2h to change drivers as my partner starts gnawing on the steering wheel before then. Those stops suggest a rough geographic area in which to look for chargers, and very often there are chargers exactly where we are stopping anyway. So I no longer feel like I need a really solid route-planner.
A model for energy usage at various speeds that you can apply across a route would still be really useful - I still use ABRP to tell me whether I can make a certain distance from a given state of charge. This will then probably not be as good on open data, as I don'tthink there are good open datasets for average traffic speeds (given time of day). The car's own model of this is somewhat opaque so I don't trust it too much.
Thanks for the elaborated response :) Maybe I am overthinking it and searching for a charger when at x% SOC is quite enough, I have no experience with EVs
For your first (long) journeys, definitely plan in advance. And don't rely on searching at a certain SOC without scoping out the frequency of chargers on your route. Where I am, this would never be a disaster, but it may end up with having to take a long detour, or being stuck on a very slow charger to be able to make progress. I guess you're in Germany, where I don't know the situation - probably decent. But there will be less densely populated areas which may still cause issues. In North America there are major routes with no chargers for more than a hundred miles which then requires a lot of care.
What I'm just getting it is that this level of care is often not necessary once you're familiar with an area. And then perhaps the impetus for OSS solutions is lowered.
Thanks for the advice. Yeah I live in Germany and I think the situation here is quite fine. Not perfect of course but fine
