A good way to check battery health?

2023 AT
Delivered Jan 2024
Miles: 19,271 (20s for first 18,078) 19s since
battery_health_level: 95.00000141561031

18 months in an Air Pure, 18k miles, I'm an 94 percent on the nose (down a percentage point since February). That said, the first time I checked it (say 3-4 months into owning it) it was already at 96-97 percent.
 
Not sure but I believe this shows my battery health at 93%. 2022 Dream Edition with 25,000 miles:

"vehicleState": {<br> "batteryState": {<br> "range": 563,<br> "chargePercent": 84.00000125169754,<br> "kwHr": 87.55999804288149,<br> "capacityKwHr": 104.28999766893685,<br> "batteryHealth": "WARNING_OFF",<br> "lowChargeLevel": "WARNING_OFF",<br> "criticalChargeLevel": "WARNING_OFF",<br> "unavailableChargePercent": 0,<br> "batteryPreconStatus": "BATTERY_PRECON_UNAVAILABLE",<br> "batteryPreconTimeRemaining": 65535,<br> "batteryHealthLevel": 93.00000138580799,<br> "evsePowerLimited": 0,

Is that a correct assumption? This was a rebuilt battery replacement after first year. Math taking the current 87.6 kwHr and dividing by 84% results in 104.2 total kWh capacity vs. the original 118 kWh implies a 88.3% vs. the 93% shown - buffer??? or what ??
 
2023 Air Pure AWD with 25,022 miles. Manufactured & Purchased in November of 2023, and in a temperate climate year round. Battery health per the API is 96 (Capacity 84.79999) despite being about 95% charged at EA. With very few exceptions, I stay within the suggested 20% - 80% SOC. (I suspect that it helps when the vehicle has not been parked in inventory in the AZ sun through a long, hot summer.)

2023 Pure AWD Delivered January 2024. 25% of charging is DCFC. Usually charge to 80%, occasionally to 95%. Regularly discharge to less than 5% (don't want to stop when approaching my destination) while traveling. 40% of the miles are traveling to/from Central Vermont where level 1 charging begins with usually 5% or less battery remaining and temperatures well below freezing (usually see -20F each winter). Total miles 47,700, original battery.

Field 11, battery_health_level: 95.00000141
 
It seems there are multiple ways we can measure the battery degradation in these cars, and it sure would be nice if Lucid would clarify which one is correct. My car is a 2022 AGT, where the original high-voltage battery was replaced by Lucid in 2024. The paperwork for that service claimed that both my original battery and the replacement battery had a 95 percent "state of health." Yet, I lost 5 miles of "100%" range immediately with the replacement battery, so I don't think they were truly the same degradation level. Maybe my old one was 95.4 percent and the new one was 94.6 percent, and Lucid rounded them both to 95.

Anyway, now after a total of four years and 14,717 miles, the battery health from the API is 93 percent (so, 7 percent degradation). But the battery capacity from the API is 100.02 kilowatt hours. As the original battery capacity for the Air GT battery was supposedly 112 kilowatt hours, this implies a degradation of 10.7 percent (100.02/112.0). Thirdly, my "100%" charge range is now 440 miles. When new, the car (with the 21-inch wheels) was rated at 469 miles of range, so a 6.2 percent degradation level (440/469).

Might as well have a monkey throw darts at a dartboard!

Hmmmm. I was just thinking about this and I wonder if the default calculation is based on a faulty assumption of 112 kWh battery pack instead of the DE's special 118 kWh pack. Because if it is, that is exactly 93%....
 
My assessment is the gap in the number is due to the difference in the usable battery vs the theoretical max battery size. The reported capacity in the log could be referring to the usable battery capacity.

In either case, no need to overthink and overanalyze this. These numbers clearly show battery degradation in these cars is very low. It is very likely the battery will outlast the car. Just enjoy the car and don't worry about the battery (while still following the best charging practice).

The Air Dream Edition has a battery pack size of 118 kWh. However, the usable capacity is around 112 kWh when new. Using 112 kWh as the base, you get 93% degradation.

What I can gleam from all the posts, estimated usable vs pack size (kWh):
  • GGT & GDE: 117.39 vs 123
  • ADE: 112 vs 118
  • AGT: 108 vs 112
  • AT: 88 vs 92
The above are estimates, only, from data posted on this thread. I don't think there are any officially published usable battery pack specifications.

Your math looks good, but I do see other counterpoints that suggest an odd set of calculations in the API. For example, the EV Database publication for the Pure/Touring AWD says that the battery has a nominal capacity of 94 kWh and a useable capacity of 92 kWh. Also, the 2023 Lucid Air Pure AWD has an official EPA driving efficiency of about 4.46 miles per kWh (with 19-inch wheels). At that rate, and with the window sticker driving range of 410 miles, that suggests a usable capacity of 91.92 kWh. (My understanding is that both the EPA and the vehicle itself apply the useable capacity for their calculations.) If the useable capacity was really only 88 kWh, that 410 mile range would suggest a whopping 4.66 miles/kWh.

I charged my Pure AWD to 100% only once, after a little more than seven months (around 5k miles) of driving, and the range showed at 409 miles, so the window sticker's 410 mile EPA usable range figure looks about right.

2023 AGT sitting at 15,xxxmiles and 93%
Have always only charged to 80% since new.
Does that seem like more degradation than I should expect?
One question I have. For the first year, I kept it plugged into my level 2 LHC and it topped up to 80% every night since leaving it plugged in was what I was told I should do.
I now only charge once a week once the car reaches ~20%. Which is better?

I think the once a week 20% to 80% would be a tiny bit better, but both are great ways to go. As for being at a bit lower 93%, my guess is that checking your VIN placard would show that several months transpired between the manufacturing date and your purchase date.

This is my 2022 GT-P, purchased in Q3 2024. Production was Aug 2022 where it ended up being a demo vehicle at Lucid until I bought it in 2024. I was the first actual registered owner. No idea on the location or SOC the vehicle was kept in the two years that it was a demo. I've put nearly 48K-ish miles on this one with countless charges up to 100%.

My Plaid X has 110K miles with both of these vehicles I've essentially road tripped them from border to border many times and I generally don't think twice about SOC. I keep it around 80 to 85% when I know I'm just going to be around town, but ahead of long driving days I always charge it up to 100%. Plaid X is at 81% battery capacity according to Tesla.
 
At 34 months and 26k miles. My Pure AWD shows: 95%
 
Is there a way to get this information for a car not registered with Lucid owner credentials by just using VIN.. It would be a great tool to screen a used Lucid to ensure battery health.
 
I have no idea about battery treatment for my cars first three years and 7,000 miles but mine shows 95%
All I really care is how far can I drive and never believe the range as predicted by the car. I’m seldom disappointed that way

2024 Air Pure 23k 89.1%. a year ago it was 94%. Level 3 charged maybe 6 times. Charged over 80% maybe 6. Times and always with level 2. May change my mind about buying it at lease end.

Try charging your car to 100% overnight, and see what range the car says in the morning compared to its EPA range.
It's possible that the pack may have become unbalanced if you haven't charged it to 100% in a while.
