Alpha Feedback - Volkswagen eGolf

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!

The winter charge times in regard to e-Golf 24kWh are highly optimistic. In the four years I've driven my e-Golf that has not been my experience.

With a temp set to -20C charging from from 28% to 83% in 14 mins are unrealistic. Might work in 20C weather, not in -20C weather. Time would be closer to twice the time.

The charge speed tapers off a lot after 75%.

Yeah, that's a known item we need to figure out the best way to implement, no models vary charge speed by external temperature right now.  Charge speed is dependent on internal battery temperature, typically, so we'd have to do modelling to figure out what the internal battery temperature is based on how long you've been driving, how long you've been charging, etc.  

I suppose we could kluge it a little bit by putting a standard multiplier on the charge times when we return them, but it wouldn't be very accurate.  I suppose more accurate than it is now.

Hi, 

thanks for a good reply. 

One other thing. In the e-Golf it’s really not worth it to charge past 75-80%. The general charge time from abt 20% to 75% is the same as charging from 75-100. Charging past 75-80% I would only do if I had to because there was no other chargers to briefly stop at for the next stretch. In Norway we also pay per minute at the charger so it’s really uneconomical also. 

I greatly appreciate that your site now also helps almost all EV’s. Keep up the good work. 

Regards, 

jpf

Agreed, we use the charge curves provided by Fastned for the two e-Golf models (link), and the route planner is time-optimized in 5% battery steps, so it'll generally keep your charging in that range.  If it's faster to charge a little bit past 80% instead of going off-route to find a whole new charger, it'll pick that instead. 

It will also account for the "stop overhead", which is the "Time  to Open Charge Port" setting, which is the extra amount of time you assign to each stop to pay at the charger, and initiate the charge.  A higher setting will mean fewer stops for longer charges, lower setting can mean more stops.

Thanks for the kind words! Also, if you've got an e-Golf, we're still looking for a way to connect car telemetry to the site so you can follow your plans in the car (and we can improve our car models).  Does Volkswagen have any kind of telemetry API, or perhaps there's an OBD reader app / PID list that could be used to get data?
