Battery degradation 3.49% after 10k miles... what's yours so far?

This thread is so degrading

I'd be hesitant to give much credence to any degradation figure that is computed before 10K miles. Simply not enough data for an accurate picture.

I don't want to check

More reason to push for a future battery swap. 400whrs/Kg and <$70 per kWhr. and 400,000 units out there in 3 years. It will be worth it if they can turn the old battery into stationary storage.

I have seen reports of a similar "report" from TeslaFi, but I haven't been able to find how to view it. Does anyone here know?

Yes, it is under menu option: Charges -> Battery Report

Here is my 2017 Model X. There are 3 ways to view the degradation. You can see I'm highlighting the 2nd one. Green line is TeslaFI "fleet".

Livestream it on youtube!!!

I have 12,500 miles and less than 1%

According to Recurrent my battery has 100% health at 500 miles.

Tessie says my battery has degraded by 3.49%. Is this just a reading error or some of you also have similar readings?

After 4,500 miles, my battery's degradation is 0.1%.

From Tessie's help center:

If degradation or capacity looks unusually high or low​

​

It's possible that the BMS calibration has drifted and its calculations are inaccurate. You can help it learn how much energy is in the battery by calibrating it.​

​

Tessie help center's guidance on BMS calibration:

How to calibrate the Battery Management System​

​

You can recalibrate BMS accuracy and rebalance the battery cells by doing the following:​

​

1. Let the battery fall below 10%.
   1. Leave it there for at least an hour.
   2. Charge the battery to 100% and keep charging until the vehicle is no longer adding any energy from the charger. This may take an hour or longer after reaching 100%.

After this process is finished, BMS calculations will be more accurate, and as a result, battery level, range, capacity and max range will become more accurate.​

I'd calibrate my truck's BMS then wait until my truck has undergone at least 10 charges of more than 5 kWh (the BMS uses the last 30 to calculate capacity).

Thanks! Not sure how i missed that. Here is mine, which seems more sporadic:

Is Tessie worth it over Teslafi?

Thank you. Dumb question. How do I connect two accounts together? For some reason, I can never find this.

FYI, it reports information from the vehicle. That information can change.

So basically, it lies.

And it really doesn't mean anything anyway.

You're welcome. Is that a Cybertruck?

Depending on where you live the winters may lower it temporarily OR sometimes an OTA will rest the BMS info and it will then lower and rise again. The 'Software Markers' (OTA versions) is toggleable in the horizontal legend area to see this. I normally have it off because there are so many of them.

Also you can change the dates at the top to "zoom' in on a particular length of time.

How do the 3 areas below what you posted show what degradation look?
