Battery Degradation After 1 Year

[Volund]

Looking forward to hearing how that goes for you. I do San Diego to Vancouver frequently and can’t imagine doing that in an EV without the same charging capabilities and range of the AGT

Going from DC to Utah, I had no issues, it's fun road tripping in the Lucid.
Covered around 2700 miles with 18 charging stops

D.E.-R owner here. After about 13K miles and two years of only charging to 80% on a 48 amp home charger (7 months of which the car had no usage) I've lost 8.8% of capacity down to 474 miles of range.

Not very happy about that.

I have done a road trip from Dallas through Vegas, up to the Lucid HQ in Newark, CA, down to San Diego, back out to the factory in Casa Grande, and back to Texas for a total of approximately 4200 miles.

I never took it below 8% and only charged it to 85% during this trip.

The car performed...like a dream!

Ask what your actual health is the next time you’re in for a service. There is reason to believe the range you see in the car is based on a very conservative estimate, and they should be able to do a better check in the shop.

I can't say from experience with the Lucid, but with a Tesla I found that occasionally charging to 100% and then using the car right away. perhaps going down to 8% or lower, then charging it up again helped recalibrate the displayed remaining range. My wife also had a Model 3, which wasn't typically charged past 80% and seemed to have lost a lot of range, especially during the time of the COVID-19 lock downs when it got little use. We eventually gave it away to my daughter who lives hundreds of miles away, and after a few trips that entailed letting the battery get low, charging to 100% or close to it (charging to 100％ isn't likely to do any harm if it's not left at 100% long) and then using it again, I found out from her that the large range loss that I thought I had didn't exist. That was consistent with actual diagnostics that showed no problems with the batteries.

I can't say whether the same thing holds for a Lucid, but if it's generally kept within a narrow range I can see how it's a possibility. Taking a road trip and seeing how much range you get also needs a point of comparison based on when the car was new, since you probably won't get rated range especially when driving at high speeds. But it might be relevant if the displayed range is off.

Did you ever use the Unofficial Lucid API to get your car's stats? I'd like to compare numbers. Feel free to DM me about that, if you'd like.

This is totally normal either way. The battery typically can lose ~8% or even a bit more of its original capacity during the first year of use. The first year is, by far, the fastest degradation period.

After the first year the battery will lose capacity at a slower rate, i.e. just a few percent a year. This is totally normal, and to be expected.

My original 100% at delivery was 445 miles (!) or 20 miles above EPA rating for the 2023 AT with AWD. After 18 months and 9000 miles, it's at 428 miles or a degradation of <4%, which closely matches my battery health percentage. For those of you jealous of my better-than-EPA mileage, I think it's misleading and that it washes out when I have sightly greater loss in actual range. But I think the degradation number is probably the result of our relatively light usage (~6k/yr). OTOH, I charge regularly at EA to 80% rather than from a home charger.
