Charging-For time is broken; it ignores it and charges indefinitely

Bug Reports

Steps to recreate: 1) Make a route; 2) Add a stop at a place that you don’t list a charger for (in my case, Erpsstaðir); 3) Tell it to charge there for a short period of time; 4) Simulate the trip; 5) Note how it ignores the time you set (in my case) and charges for however long it wants (in this case, 42 minutes)

    Hi, and thanks for the detailed report!

    We looked into this and can explain what's happening. The "charge for" time works as a target, not a hard limit: if the time you set isn't enough to reach the next stop, the planner will charge longer to keep the route completable. That's intended — it prevents plans that would leave you stranded. In your case the stop had no listed charger to charge at, so the extra charging needed for the route showed up on the plan.

    Where we agree there's room to improve is the display: the stop can still show your original "charge for" value even after the planner has charged more, which makes it look ignored. We've noted that confusion.

    Thanks again for the clear write-up! 🙏

      Thanks for reviewing this! Unfortunately, I think there’s still a problem. First off, it didn’t have to violate my charge time constraint - it chose to. You can see that it knows at least of both the chargers at Bjarkarlundur (just after the road turns west into Vestfirðir after crossing off the top of this map) and Flókalundur (far west in Vestfirðir, nearly to Látrabjarg, where this round-trip route turns around). It also knows of others. But it entirely skips Bjarkarlundur on the way there. And on the way back, it likewise skips Flókalundur. So it’s skipping fast chargers, and is instead hanging around at this slow charger for vastly longer than I told it to, which is a complete waste of time. It still has 74% left when it gets to Erpsstaðir. There’s Búðadalur literally just 16km further up the road, with dual 150kW CCS chargers. Why force it to hang out at a slow charger for three times what the user said?

      Furthermore, if someone sets a charging limit, they mean it. A person who sets a charging time at a slow charger almost always means “I’m going to be at this location for this amount of time”. Often it might not even be physically possible for them to stay longer than their limit.

      The behavior here seems defective, not the documentation.
