Charge Limit

[westhouse1983]

My Lucid Air GT has 5,500 miles. I have leased it since December of 2024. Today I charged the vehicle to 100% in anticipation of a longer trip. I have only done this twice before and when the charging was completed on both occasions, the vehicle showed 512 miles. This morning, following the 100% charge, the vehicle showed 499 miles. I would be grateful for any explanation for the reduced mileage following a 100% overnight charge. Thank you.

EV batteries lose some energy capacity with time and use. Your car periodically re-evaluates the capacity of its battery. It has estimated that your battery holds about 499/516 of its original capacity, or about 97%. This capacity estimate is just that, an estimate. This estimate may go down, and occasionally up, depending on many factors. EV batteries tends to lose capacity more quickly in the first year, and more slowly after that.

The actual range you get will depend on how you drive, and the weather.

Might wanna swap to State of Charge for the display rather than range. Range is an ethereal thing.

Thank you for your thorough response. Even
if it is just an estimate, I must admit to being surprised by the loss in battery capacity in such a short period of time and relative small amount of mileage. I certainly hope for a lesser battery loss curve as the vehicle ages. I am also glad that I decided to lease the vehicle. Thanks again.

Don’t stress about it. I’ve driven over 71,000 miles since 2022, and my battery still retains 95% of its original capacity. The biggest loss typically happens in the first year, and even then, it’s minimal. After that, degradation slows down significantly.

Just think about how much wear and tear an internal combustion engine would have in that same mileage, transmission issues, regular oil changes, and brake and rotor replacements. With an EV, you're already way ahead in terms of long-term reliability and maintenance, whether you’re leasing or owning.

Battery degradation is often overhyped. In practice, it’s not something most owners ever need to worry about.

There are loss curves out there if you're interested. Out of Spec Reviews did a Q&A video recently and there is a screenshot of the battery loss curves for 3 types of battery chemistry. High temperatures and high states of charge are not your friend, with a non-proportional level of loss occurring for long stays over 80% SOC.

Thank you. I will relax and continue to enjoy the Air.

Thank you. I am familiar with Out of Spec and will try and find the video to which you refer.

Mine never showed the rated range from the onset, nor did it lose range (as displayed) in the first year. My real concern is whether I'll ever end up needing an additional charging stop in my life due to range loss. I'm assuming that battery capacity will continue to grow, but even with my 2014 Tesla, I'd be hard pressed to find a trip that I've taken that would require more charging stops now than when the car was new.

There's the theoretical problem of having a charging station every mile or two and having to stop a few miles early due to range loss. But in real life, if you take a 500 mile trip, and stop as many times as health experts recommend, you won't have to charge at all on most of those stops and might get by charging only once at one of the rest stops without delaying your stop.

Thank you. The issue with my trip is the paucity of charging stations where I am heading. Over time, this will improve as the US charging infrastructure gets better.

19:54 here, overall a worthwhile video for me:
