Alpha Feedback - Audi e-tron

Recommended Posts

To verify and improve our models we need your feedback.  There's many ways we could use help if you actually own one:

  • Drive a plan and compare it to the actual battery used.
  • Drive a plan with the browser active, and update your actual battery percentage in the browser.
  • Contribute data via OBD or other methods.

The best way to improve the data is to provide data directly from the car.  Connecting your car not only improves the models, but allows you to follow up directly in the car while driving! We have several ways of doing that, but we need your help to figure out what will work with your car:

  • An OBD reader can be used in concert with a custom app like LeafSpy, or a PID list and Torque Pro.
  • If your manufacturer has an API to access data from the car we can set up access to that API, like we do for Tesla

If you're familiar with either of these, contact me at jason@abetterrouteplanner.com and I'll help figure out what we need to do to connect your car!

Thanks for providing feedback!

Hi. I ordered an Audi e-tron, delivery in June. Looking forward to connect with ABRP. 
Is there a way to connect this routeplanner to the car? Or do I have to manually input all the stops of a trip?

Yes and no:

Car --> ABRP - We currently don't know of a way to get Audi E-Tron data into ABRP.  For other cars we've got OBD apps, or app interfaces that allow you to follow your plan with live data from the car.  Of course, if you find a way to access that data, let us know and we'll incorporate it!

ABRP --> Car - This one is easier.  Presumably the E-Tron will have Android Auto / CarPlay, so you have a couple of options.  I personally really like Google Maps navigation, so I put my phone on a mount to the side of the main screen in my Bolt.  Plug it in to launch Android Auto, then unlock the phone and launch ABRP.  Once I have my plan up in ABRP, I hit Share > Share Next Step.  This opens the next step (Charger, waypoint, whatever) in Google Maps (or Waze, or whatever is your default).  Once you start driving, ABRP enters driving mode automatically.  

If you have live car data, the driving mode follows the plan with a graph and predictions of your arrival Charge %.  Since we don't know of a way to get live car data for the E-Tron, we have an estimation mode, with a large battery icon that tells you what we think your charge % currently is, and you can adjust it up or down to match your actual %.  You can try this out right now in your current vehicle if you want.  This does two things, it updates your arrival estimate, and offers replanning if you won't make it to your destination, and it helps us make the driving model better so we produce more accurate plans in the future.

Hopefully that answers your question!

Based on the recent e-tron EPA range numbers and video reviews that include consumption, could you update the (alpha) e-tron default consumption values to a more accurate 425 wh/km (@65mph)?

Good suggestion, though 425Wh/km is not realistic.  Everything I'm seeing shows realistic consumption going to around 254 Wh/km (typo on your post perhaps?) Anyway, set the consumption values for the E-Tron to match.  A little worse than my original estimate, but not by much!

Jason,

Yes, it was a typo, I meant Wh/mi (not Wh/km).  The EPA mixed driving rating is 409Wh/mi (83.5kwh usable pack capacity/204mile range).  At a constant 65mph, the consumption is a bit higher.  I recommend 425Wh/mi based on all the data that I've been following.  I override the value in the planner with this value and I think it gives fairly accurate results.  Of course, logging real world data will be best when its available.

Sounds good, I'll bump it up to 425Wh/mi @65mph, let me know if that more closely matches your experience.  Thanks for taking the time to help refine the model!

FYI, that charging curve may not be accurate because it may have been initiated after a 200kph autobahn test run.  The initial heat build up in the pack may not be representative of average highway usage.
