Alpha Feedback - Renault Zoe

[Bo (ABRP) 5]

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!

Going on a roadtrip tomorrow. What's the best way of reporting from my Zoe? 

[perkabolo 0]

Is this at all helpful? https://github.com/edent/Renault-Zoe-API

[Brian D 3]

The Zoe has a custom app for reading the data, called CanZE. Google Play.

How can we use this to provide data? Also, would it be possible to get a Renault Zoe sub-forum?

 

EDIT: if you look at the settings on CanZE it allows for logging of the data to the sdcard. I'm not sure if the format is suitable though.

I have some logs from canze from today's trip. The predictions from abrp worked perfectly!

Glad to hear we were pretty close on our prediction! Does CanZE allow logging to a server? That'd be ideal, as it would allow you to follow along with the plan in the car.  We've been aware of the Zoe API, just never had enough time to implement it for the site.  Do you know if the API can access car data while driving? It's very nice to build a plan and follow along with that plan while driving, to see how well it matches.

[Brian D 3]

Yes, well actually I found that the route planner was showing worse consumption (I drive eco) for me but I adjusted it slightly and then it was accurate. The only other data I had given was SoC, temperature, and degradation. The lattter was important as my car has the common Zoe 22 BMS bug which shows greater degradation (mine is 32% but not really). Trying to get Renault to do the update, but it was helpful that the routeplanner allows for degradation.

I will wait until after the update before submitting data, but it's one thing to keep in mind for your Q210 & R240 data as some of those cars may be impacted. I will check in the output on CanZE to see if it identifies the BMS version. That may help you to have cleaner data for the 22kWh models.

I'm not sure that the API will allow frequent enough polling. Even on their own website ZE Services, the polling is minutes. For CanZE I can't see an option in settings for logging to a server. Here's their website for some more info - https://canze.fisch.lu.

As Brian said. Not possible to log to a server from CanZE today. Not sure about the limitations in polling time for the Zoe API. I belive renaults own ZE app has a 20 minute limit. How often do you need to poll in order for it to be meaningful?

Did a drive back yesterday, not as good a match as on the way up, but strong winds and limited speed beacuse of traffic made it almost impossible to get all the factors right. But still not more than maybe 5% off.

[Brian D 3]

@perkabolo I checked it out and I found it more accurate by pushing the Reference Consumption from 4.76km/kWh to 5km/kWh. This is 5%!

Now, it depends how you drive of course. I tend to try use regen to my advantage as much as possible, generally slow and steady but some bursts to get up to speed fast.

 

Out of interest, I turned on the sdcard dump for CanZE and it's saving multiple points on various SID's per second.

[Jason (ABRP) 22]

Ideally, I'd need no slower than once per minute to follow a plan, that's still a pretty slow update rate.  I've asked the CanZE developer about adding server logging, but they weren't very receptive.  If you wanted to ask as well, demonstrate user desire for the feature, that might help.  I just need them to send a Rest-like request, something like:

http://abetterrouteplanner.com:4441/leaf40?user=jason%40abetterrouteplanner.com&Lat=29.57367706298828&Long=-95.02268981933594&Elv=-21.156829833984375&SOC=96.4375&Amb=85.1&ChrgMode=0&ChrgPwr=0

Should be pretty easy to implement if they were so inclined.

Opened a feature request with the CanZE team.

@Jason (ABRP) would you be able to share a graph of the consumption on the Zoe in your model? I'm interested to see how it compares at lower speeds.

[Jason (ABRP) 22]

At the moment the driving model is analytical, it's only slightly based on real-world data.  As a result, it tends to be the most accurate in the region where we calibrate it (110km/h), and divergent elsewhere until we get real-world data (CanZE or plan-following in your phone, correcting it using the battery display).

So yes, I could share it, but I'm not sure how accurate it'd be at lower speeds.
