Planning Logic

Recommended Posts

Hello everyone! Tried to do a search here. Trying to figure out the logic of the planner.

Planning quite a hike from CO to DC, and it seems like a lot of the stops only have me charge maybe 15-25 minutes rather than longer. Is there a way to specify fewer stops with longer charging to minimize the number stops along a cross country drive?

Thanks!

One way you can encourage the planner to make fewer stops is to increase the setting for additional time needed for each stop ("charge door open time" or something similar).  It'll add time to each planning stop, but a higher value will lead to fewer stops.

Thanks for the reply. Is the default charging stops with a 5 minute reply the fastest route? After changing the overhead time to 30 minutes, it actually added 4 hours to the total trip time so it was much faster to stop more times and charger shorter durations which kinda makes sense since charging rate decreases as battery approaches full. 
 

I’m assuming the best way to get the fastest route overall is to change the overhead time to 0?

Thanks!

The algorithm definitely prioritizes minimizing overall time, so if it can get away with shorter stops, it will.  Generally, that means charging to just the level you need to get to for the next leg rather than longer charge times to over 80%.  I also generally means looking for ways to drive down to as low a SoC as is reasonable on each leg.  This can lead to the lots of short charges you're seeing.  I personally enjoy this a bit, stopping for 10-15 minutes every hour and a half seems less like you're sitting around than stopping for 45 minutes every 4 hours, but that's definitely just a personal preference.  Adding to the charge overhead time is a workaround, though if you've got 8 charging stops, then that adds a lot of time to the perceived route that you have to remember to subtract out at the end.  There has been some other discussions in the forum suggesting a minimum stops priority rather than fastest time, so I'll check with the dev team on if there are any plans to implement something similar.

@sfzpilot Here's another possibility if you're looking to do longer charging stops.  After you create a plan, go to your first charger and click the "Long Break" icon (looks like a Hamburger).  That will tell the algorithm to charge there for longer (up to an hour, I think).  Let it replan, then go to the next charger and do the same.  In this way, you can make sure that each of your stops charge to your max charge level (I have mine set to 80%, since that's mostly when fast charging drops off).  A bit more manual, but avoids artificially adding a bunch of extra time to the route.
