Thing is, it has been this way from the day I got it, so unless it was degradation on the lot (in which case it can be argued that it should not have been sold in that state), it can't be that.

My Lucid Air Dream Edition (Range Model, 19" Wheels) with a 520mi full charge is now at 489mi at full charge, with about 38,000mi on the odometer. The battery was replaced at 18Kmi, so about 20K for the current battery. That's about 6% degradation. My range dropped from 520 to about 513 after...

I think the max capacity is almost more telling. After 2 years my GT battery was replaced last June and max capacity was 101kwh. A year later I'm at max capacity 100.1 and when I charge to 80% I only have 80.119kwh available. So by my calculations I've lost ~15% of battery capacity but my...

👋 Yes, hi! Share away. It's public info. I'd suggest sharing much longer term data from sources like this though: https://www.nimblefins.co.uk/study-real-life-tesla-battery-deterioration After all, Airs are only about 4 years old at most.

Here is my battery degradation in five months since brand new: Field 11, battery_health_level: 97.50000145286322

After 3.5 years and over 20k miles my battery health shows 93.6 but my kwhr capacity shows 105.8 kWh which assuming a 118kWh original capacity implies a 10.5% degradation. Not sure if that shows a discrepancy between battery health and capacity, but in any case I guess a 10% loss in 3.5 years...

...are also *very hot*, and that means… nothing to cool! :) If you’re not DCFC charging though, you should let it cool the batteries down instead of turning on preconditioning, to reduce battery degradation. That said, do have service check it out just in case, if they’re already scheduled.

...buyer. I am against a lessee being limited or charged based on how they used the battery. There are way too many factors to battery degradation for that. Should people in hotter climates be subject to a fee, because it degrades the battery faster? Not at all. It would upset me if Lucid...

Hard to tell if that final question in your post is condescending or not. I like your posts in general, so i'm going to assume it wasn't and was asked genuinely if I am following your thought pattern. I hear you on the battery warranty. That's a reasonable point, but at some point these cars...

...is the battery health. They should ding lessees who always charged to 100%, figuring it was just a lease and therefore long-term battery degradation would just be someone else's problem. THAT would be in good service to the second buyer of the car, though I imagine it might require changes...

I have tested this empirically, with data. I have tested not preconditioning, preconditioning for 10 min, 15 min, 20 min, 30 min, 40 min and 50 min. Preconditioning for about 40 min makes a huge difference in charge speed. Past that it doesn’t do much. Fewer than 15-20 min and you may as well...

I appreciate the tutorial in battery temperature vs charging speed. But that wasn't what I was talking about. Let's get grounded in some fundamentals: > charging batteries is a thermodynamic process. As such, it is temperature dependent. "Typically", higher temperatures is favorable to...

Amen.

Have a materials science background and know batteries pretty well. I have seen nothing peer reviewed that shows enhanced degradation from charging EV batteries to 100% nor DC versus AC charging. It is correct that leaving a battery charging for a long time can cause slight loss of capacity. In...

Yup. Your behavior might have cost you as much as one mile in your estimated total battery life of at least 100,000 miles. Shocking.

...to take a lot of punishment. All the crazy inconveniences people put themselves through to help save a tenth of a percentage of battery degradation are really not worth the headache. The real guideline is simple: don’t be totally stupid with your battery. Don’t DC fast charge your car every...

Tom Moloughney of "State of Charge" recently interviewed Emad Dlala, Lucid's SVP of Powertrain. Dlala dropped something of a bombshell on Moloughney, He said that fleet data Lucid was collecting on Air battery packs showed that a mix of Level 2 and Level 3 charging was producing the best...

So I had a round trip to Corpus Christi today from Austin--221 miles leg/442 round trip. The only EA chargers are in San Antonio--roughly 80 miles from my house. I know the following: 1. Charging the battery to 100% should be avoided 2. DC Fast Charging should be used sparingly 3. Don't let...

True for all lithium-based cell chemistries, which includes Lucid. But also good to remember that this does little for the health of the battery itself - rather the opposite if anything. I've encountered people who almost religiously tried "calibrating their battery" by ramming it up to 100% and...

...of the reasons I can’t bring myself to buy something like an EV9. With an EPA rating of 290 miles, between actual performance + battery degradation, a few years after delivery, on a winter roadtrip, you are looking at 200 miles or worse. I don’t want 3 charging stops between Philly and...
