  • 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.


  • 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.



  • I typo’d “undirected” if that affects anything.

    My point is, people talk about this as if it’s the plants having a nice chat and a cup of tea and talking about politics. It isn’t - it’s more like a dog being able to smell some dog piss and understand something about the dog that pissed there.












  • On these scales, the accuracy of our observations should reduce our confidence though. It doesn’t make sense to confidently say that, in 200 trillion years there will be no stars, because our observations of the rate of new matter creation (approximately zero) have a margin of error which allows for there to still be some
