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...

It was the end of winter so I averaged maybe 2.8 mi per kwh and it was about $500 most charging was$ .55 -.60 per kilowatt hour. Any time you're on the road on the road utilizing public fast charging. It's similar cost to a 25mpg vehicle. Last year I drove 60k in in an EV in town and it cost...

...at fast chargers, the answer would be $300. Of course, this answer ignores other costs (depreciation, oil for an ICE vehicle, battery degradation for an EV, etc.) but even at that cost it is less expensive than doing the same thing in an ICE vehicle. I did the original calc because I...

It really depends on your use case. For you it looks like it makes sense. For me, my use is to drive from San Jose to Lake Tahoe (summer and winter) which is significantly uphill and cold in the winter. After 1-2 years of batter degradation, having that slight buffer makes the most sense. We...

Have pretty exclusively charged on DC fast chargers and haven’t seen any appreciable loss of battery life, even over 60k miles.

All good! The car's battery will slowly degrade with time no matter how carefully you manage it ("calendar degradation"), so there's no substantial payback to super-careful behavior that reduces the utility of the car or your enjoyment of it. Even DC fast charging, according to Lucid, seems to...

I think mine is down 15% at 90k miles (271mi full charge), I thought that was normal. I thought most of the degradation in the batteries is actually calendar aging. I see reports of cars with 300k+ miles with similar degradation. I have started charging to 55% for the last year. There are so...

My pack had higher degradation than most for the miles- off over 15% from new in a bit over 80k miles. I did a good job keeping the battery below 80% unless road tripping, but I also did well over 100 supercharger stops where I’d come in on fumes, low single digit battery remaining, sometimes...

I see five main factors negatively impacting current Lucid or EV valuations, two to three of which I think will change medium term. 1. Battery longevity and cost. Generally the other mechanicals of EVs are both simpler and last longer that ICE cars, but the battery is the weak link. Replacement...

Useful information. Have a 2023 Air Touring with 21K miles (purchased new in 2024/01 from Lucid, manufactured 2022/11, so sat somewhere in the desert for a year or so - sand was still all over car at delivery. Not sure how they treat their cars and batteries in storage) Battery Capacity: 84...

You can tell you are in California. Being able to do 56K miles of fast CCS charging on the east coast would be a nearly impossible feat . . . especially using Electrify America, where a fully-functioning location without an hour-long wait to plug in has been as scarce as hen's teeth. With the...

I think my personal experience however, anecdotal supports this notion. I have gone 56k miles and super charged 99.875% of them… okay more like 95% but have seen little degradation; 4%-6% in two years of ownership. And I drive the Lucid 19” hard and put her away wet, absolute joy to drive...
