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

[scottf200]

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

A quick google search showed:

Multiple TeslaFi.com accounts can be linked together from
Settings->Account->Vehicle->Create A Fleet Account.
Once a fleet account is created a new menu option will appear titled 'Vehicles' from the menu bar where you can easily switch between accounts and manage your fleet account.

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

I have the same problem my full charge now is 290 miles

Somewhere between zero loss and 0.3% loss after 4,200 miles. Last time I charged to 100% it went back to 318 miles with the AT tires.

I have a 2018 Model 3 Long Range with 71,000 miles that charges to 306 miles out of the original 310 miles almost 7 years ago.

You're welcome. Is that a Cybertruck?

Not yet, not enough miles on it. This had data back to 2020, as another hint ?

Mine is zero % after15,700 miles. How can that be??

I charged to 100% last night on a return trip, knowing i would use it immediately. The last 1% too a LONG times, about 20 minutes but it charged to 315 miles. I have 16,500 mile on the truck, as of today. Yesterday was a 500 mile day.

No data collected. There should be a blue dot on the chart ? for each charge session of at least 5kw.

I see those. It has come down some but not even 1% yet

Charged to 100%. 10 times
Usually 80% is max
About 5000 of the miles are Supercharger
At home I have it set on the wall charger to less than 20 amps most of the time and go as low as 6 amps whenever time allows.
Slow slow charging is the best by far.

Not to be argumentative (says the guy right before starting an argument lol) but I see no such data in the charts you posted.

This is what mine looks like:

I can even run my finger over the chart to get the specifics of each data point.

I’d also add on mine I never expected to own it for as long as I did. I only sold it two weeks ago so it was by far the longest car I had ever owned. I say that to say this.. I charged that bad boy up to 90-93% pretty religiously in my first 18 months of ownership settling down to 85% and finally to around 79% the last 4yrs. Not sure if my more extreme case was also due to how high I was charging it daily but thought I’d point it out for the group. I hope the CT doesn’t lose as much.. but I also won’t charge it beyond 70% very often.

There are many threads on various forums that discuss this stuff; one of them is in the link below.

Based on the 338 pages of information in that link, if one doesn’t require a battery always sitting at >54%, then get into the habit of only charging it up to 54%.

Obviously, long range trips that require top ups to 100% aren’t an issue, the issue is days/weeks/months/years where the AVERAGE state of charge is above 54%.

Long story short, it’s not the “cycles”, but the “calendar aging“ that will have the largest effect on long term battery health, and one way to minimize calendar aging is to keep the AVERAGE state of charge below 54%.

I’m gonna believe Jason from Engineering Explained over pretty much everyone so..

Preface: I am NOT a subject matter expert on this stuff.

I know that my May 2018 build TM3 had sufficient “top end buffer” that I never saw any degradation from the initial 499 km stipulated range until the car was three years old.

There was degradation, naturally, but I couldn’t “see” it until a few years went by.

Perhaps that technique is also employed with these Cybertrucks (?).

Whatever works best; I figure everyone (that plan/want to hold onto their EV beyond eight years) will end up doing their own research in this area until they are satisfied with being familiar with the overall results that various research organizations have published.

Edit: grammar.
