Model 3 Battery Degradation 3% after 1 year 4 month use

[Falcon3]

Car specs: Model 3 LR RWD with 42,000km/26,000 miles after 1 year 4 months.

Situation: I've been driving and charging the vehicle to 90% every night. Last couple of days I noticed that the car only charge to 87% now. 3% degradation seems high for 1 year use.

Questions:
1) Are any other owners experiencing a similar situation?
2)Do I need to re-calibrate the battery?
3)Should I contact Tesla?

Have a look at my post in the following thread. Plenty of reading material there.

SR+ at 90% now showing 210 miles

Thanks! This was helpful. I think I should have searched before posting. Lesson learned.

IMO, 3% is pretty good. That's about where I am in a similar timeframe.

 

[woodisgood]

Yep, similar amount and timeframe...s'all good man

I'm not even sure I understand your "situation"? You've set your car to charge to 90%, and it doesn't? It stops at 87%?

WAY too many threads regarding this. Please search.....

just want to point out that if you are gauging your battery degradation on the miles listed in the GUI when charging, that will not be an accurate way to assess degradation.

Stating this, as in the end this is how most people are measuring battery health.

 

[ewoodrick]

This isn’t battery degradation, not even the right way to calculate it

Correct. Instead of stopping at 90%, it stops at 87%

My take is that your adjustable charge level bar is off by ‘1 click’. The % should never change, only the indicated range at a specified %.

Is there anyway to re-calibrate? What I read from the other threads is to discharge to 5% and fully charge to 100%.

you can use the API to set the charge level to an exact number, if you feel adventurous.

Move the slider again in the car or in the app until it "snaps" to the 90% level. And try again.

This issue has nothing to do with capacity loss - in fact there is no way for you to easily gauge capacity loss when you use % as you are doing. Which is fine.

Defective batteries will sometimes refuse to charge to 100% but that will give you an error message saying so and that is pretty rare (so very unlikely to be your issue here).

Funny thing, just the other day I charged my car to 80%, slider was on that mark. But when the car stopped charging it showed charge of 83%! I had recently taken it down to near zero (1% I think) so it may have recently recalibrated. I’m not sure if this means I lost range or gained it, but apparently the slider stops can get confused.

I slid the battery bar down and back to 90% stop and today, it charged to 90%. Seems like this fixed the issue. Many thanks for your helpful insight!

Tesla Model 3 Performance here, had delivery in early October 2018, approximately 66% of total charges on Tesla DC Superchargers (yay for lifetime free supercharging) with other 33% of charges using 120/240V AC where I almost always charge to 90% though sometimes to 100% if I'm taking a long trip. Per Teslafi I've had somewhere between 2.84%-3.08% degradation after driving 43,625.87 Miles. (Note: I didn't start using TeslaFi until 12/08/2018 at 5,788.28 miles)

For almost 44k miles, and charging to 90% and 2/3rd on SC, 2.5% degradation is pretty excellent.

I've supercharged about 300 kWh over the past 7 days. I noticed I lost about 2.5 miles at 90% charge (I keep the indicator on miles instead of %), whatever that means, but whatever, it's not like I'm going to drive it down to the last 10 miles.
