So should I be impressed with this range? I do not think so.
after 17000 miles

that would be about 220 miles at 100% and about what I get on long road trips of 1600 miles all 70 mph driving. It’s also December so coldness could be pulling it down.

i friend with tesla model S from 2017 claims about -1.5%/yr (did 2 cost to cost trips in it)

That’s about what I have heard too, but heard it is a little more in the first year.

Its a bit more difficult to compare with a Tesla I think, because I believe in the Teslas you can't OBD the exact kWh numbers no? (I don't know this for sure). For example my kWh is down 10% but my range is still about the same if not just a few percent down.

Yes you can there is interface cable on can bus network that has to be purchased and it will work with obdlink and app on phone for Tesla.

Oh so Teslas battery Wh really only degrade 1.5% in a year? So if my ID.4's degrade 10% what does that mean......

 

[crimsona]

I am down to 10.2% degradation or 69150, following the "waves" of cold / warm seasons. It seems the degradation still pretty linear so far.
The range... it may have degraded just a little bit but nothing close to 10.2%.... how long it will stay that way... we will see.......

Are these charts or dataset something that is recorded automatically by carscanner? Or are you manually writing it down each time? I do something similar with My Leaf and Leafspy so would like to continue the habit with ID4

Did you actually own Tesla for at least 6 months and done testing it to see how Tesla pack age over time. NMC chemistry has beaten to death already over many online forums.

car scanner can record the data if you turn on that option. For anything useful, you have to manually extract the Max. energy content and put it into a spreadsheet like this one:

Battery state of health tracking spreadsheet

Here is how to get your battery health SoH number. You need an OBD dongle and the car scanner app (android or iOS.) read the Maximum energy content of the traction battery (MEC), and the battery min. temp. Degradation is the amount your battery MEC has dropped from new 77kwh for 2021-22 or...

It would be nice if someone makes an app like leafspy that pulls it out and graphs it over time.

Leafspy just records all the data into a CSV file every time I open the app, and then I just chart the State of Health column in the CSV in Google sheets.

From what I can tell, Carscanner can do something similar by recording enabled by default, and then click disconnect to log the result? does each session create a new CSV, or are they all on the same CSV file?

Each session is its own file. It uses its own format and you can manually Export each to a CSV. If you record often it will fill your phone.

I made a screenshot of my car scanner app if I want to record data on my spreadsheet. I could pull the data that car scanner app records in the phone, but I found it is too much data and less convenient than just opening my screenshot and plot the data that way every few days or so (whenever I remember).

I never owned a Tesla. Someone else mentioned 1.5% per year or maybe I misread.....

That was misinformation. Better sources like this fleet company who averaged the data from 6300 cars say that the average EV and Teslas are degrading 10% in 4 years. Compare many brands and models here:

i mentioned the 1.5% - i came from a friend who owns the tesla

But there is also unknown, Tesla has changed chemistry over the years so it is not real world scenario. Small changes in NMC chemistry move the envelope in different ways....Tesla is focused on performance and speed of charging with 50°C + for battery cells, that changes characteristics of SOH.

 

[Rachel]

Maybe in a few years we all meet in Chattanooga, driving a Tesla, and pick up our new battery for the id4 at home in the garage. Ok ok just kidding

😂

Well that is still better than my battery 10% in 1.5 years 😲

 

[Erhard]

I do like your gom increase though 🙂

Mine is 70600 kWh and at 80 % soc I get in summer 210 to 220mi.

 

[ddx]

Mine is down to 68800 but somehow my range is still about the same .
Since about November 2022 when it hit below 70000 it has not moved down much, I am hopeful I hit "the flat curve" and the rate of degradation is indeed slowing down...

Hi there, in addition to the posts above: We recently launched our eFlow app, which allows you to access SOH data, similar to other scanner apps, but in a more convenient way. It works with cars from the ID family, as well as EVs from Audi, BMW, and Porsche. The app lets you compare your SOH to the fleet average, project SOH trends, track changes over time, and gain insights into metrics like battery and cell temperature.

You can check it out here: eFlow | The essential battery diagnostic app for your electric car.

Feel free to drop us any feedback!

 

[Perry Rhodan]

Did anyone pay the fee to unlock all features for the eFlow app above?

It looks neat but at $35 CAD per brand it’s rather expensive compared to say car scanner.
