Default ABRP issues

I have read in many threads people raving about ABRP but I seem to struggle with it doing stupid things.

I was trying to help my wife plan her trip home the other day and ABRP came up with the following : https://abetterrouteplanner.com/?pla...5-23e28259a6c4

Couple issues, why did it send me 9mi in the wrong direction instead of use the charger that she was parked at. My only guess is that ABRP (incorrectly) thinks the charger she was at is a 40KW instead of 50KW charger.
Secondly why can't I fix this in the route. Why can't I select the charger she is at and do a 'use this charger' .

I believe ABRP attempts to optimize for both total travel time and charging cost. It does not seem to care too much about total distance traveled, or whether it routes you "out of the way".

In your case, you can coerce ABRP to do this by adding the nearby charger as a waypoint, and tell it how much charge you intend to take on at that station: https://abetterrouteplanner.com/?pla...8-86f161db541c

The way I did this was to click on the nearby charger, then click the "add waypoint" button. This takes you back to the waypoint list. Click the gear icon next to the charging station you added as a waypoint, then configure how much charge you intend to take on at that station (I configured it for 100%). Then re-calculate the route, and there you go.


The other thing I notice is that you have ABRP configured with a departure SoC of 40%. This might be intentional, as you are probably trying to compute how long you'll need to spend at the nearby 40kW charger to make it to your destination. I don't know of a way to make ABRP forcibly use a charger, without also telling it how long to charge, or to what SoC% to charge to. I just made a few educated guesses and arrived at this: https://abetterrouteplanner.com/?pla...a-2c7aad183d73 which says you need to charge to 57% at the 40kW charger to arrive with 20% remaining.

One issue noticed was departing SoC was 40% in the settings. App must have assumed that's all you could at the starting position.
After fixing, setting to 100%, all seemed well. This app takes a little getting use to in terms of initial settings. After mastering it, the help is very useful.
Hope this was a help.

Another thing to consider is that as great as ABRP is, it's a free service. And nothing is ever "free". There's a very real possibility that ABRP is paid to prefer certain charging networks, when the difference in total trip time is under 30 minutes or something.

But I hope it's not as sinister as that -- I hope it's just ABRP's algorithm putting too much weight on selecting chargers with a higher charge rate.

That's a keen observation -- and that may be the case -- ABRP may indeed be assuming that your starting SoC% is inclusive of any charging you were able to do in a 1-mile radius or something.

Thanks skaven81 for the waypoint trick that at least allows me to get it to use the nearby charger even if I have to play with different guesses to come up with something that works.

The reason I had the starting SoC at 40% was to try to recreate what had happened a few weeks ago. My wife left Rochester at 100% and drove to a place near the good will, did her shopping and I was trying to calculate the route back. So the car had ~40% left so I set that as the depart SoC and was hoping it would calculate how long to charge at the goodwill but I couldn't figure it out.

She ended up grabbing some food and sitting at the charger for ~20mins and made it home with no issues. Was her first road trip with the car (and the in-laws). Car behaved well but confusion over ABRP and getting the Greenlots charging going didn't help alleviate any range anxiety

For grins, the other day I planned a router from Boston. MA to Dubois, WY.

ABRP gave me a whole buttload of NOPE! In researching it further, I fould that unless you're driving a Tesla in Wyoming, Montana, Minnesota, and the Dakotas, you're not finding ANY DCFC devices in these five states.

Route through Idaho Falls, and you can make it. Only need a fairly quick 50kW stop, 18 minutes in Jackson, WY.

https://abetterrouteplanner.com/?pla...7-fb5222169ed6

Dubois, Wy has a dual L2 changing station, one side of which is working as last report. Along with multiple RV parks. So getting back isn't a big issue.

I've planned a trip into the Black Hills that I might actually take some day. It is not easy to get into this area, as charging is very limited.
