Has anyone else with an Air Dream Experienced Reduced Charging Capacity?

I set my charge limit to 95%, which should be 494 miles of 520 capacity. Lately, I am only charging to 438 miles, and was charging to 450 just a couple of weeks ago. Outside air temp is 42 degrees. I used to be able to charge to around 490. Any other Dream owners experiencing this? Car is 27 months old.

I do NOT have a Dream Edition. However, I'm not sure if you noticed, but one of the more recent updates (maybe 2 or 3 updates ago now?), included a 'more realistic' estimator for the battery capacity. I noticed a small change after I was charging too after that update. BUT not as significant as you either.

Also unfortunately the battery warranty only kicks in if you go below 70% capacity (something I noticed when I purchased).

There is a link from Borski somewhere on this Forum that will allow you to check your actual battery capacity. My Dream P is just at two years old and according to Borski's link my battery capacity is at 108kWh vs. the 118kWh originally. So I have lost roughly 8% capacity, which assuming the original 450 mile range (which I never came close to achieving) my current optimal range is somewhere around 414 miles, again not at all realistic for my driving style. I average 3.2 kWh/mile so my realistic maximum range is ~345 miles.

Assuming you have the DE R, my guess is degradation. My battery is down to 107 kwh now, which would put me at 409 miles vs 451 originally.

Doing the math, if your battery is degrading similar to mine, puts you right in line with what you've experienced.

I may be wrong since I’m going by some distant memories, but the rate of degradation I’m seeing here seems greater than some Tesla #s I recall. Again, I could be wrong. Personally, I’m already down to 87 kWh after only 5,000 miles on my Pure AWD.

I’m fully aware the greatest rate of degradation occurs early on, but still…

I suppose this is why I'm only seeing 406 miles when going 100% the other day on my road trip instead of the 410 miles I saw back in December after a full charge on level 2 overnight! I only have 7300 miles on my Pure AWD right now. I haven't run anything to figure out what my current actual kW capacity is though.

10% within the first 2 years is on par with what Tesla cars were showing

Okay... here's what mine shows:

"capacityKwHr": 87.3199980482459

^ 2023 Lucid Air Pure AWD with 7275 miles as of this moment.

I’m actually a tiny bit worse @ 87.30999804846942, despite have only 5,000 miles.

Sometimes I wonder how accurate these numbers are, or if they’re really telling us what we think they’re telling us. I get suspicious when a number of people post their results and so many of the numbers in the string are identical. As an example, yours and mine both show ‘9998048’ in the result. It boggles the mind there could be that kind of ‘sameness’ in the results. I’ve seen the same thing in the results of others.

Could it be the numbers further down the string represent some other values? Who knows?

Maybe its a value the battery rounds to?

Strange rounding #, no? Over at the BMW forum there was a period when people thought they had found the same capacity remaining # for the i4. But as more results were posted the #s just weren’t making a lot of sense. So who knows, the automakers will never spill the beans.

I wonder if it has anything to do with how often or when the last time it reached 100% and did 'battery balancing'.. or does this not happen/isn't really a thing any more?

I remember on my former Spark EV (my 1st EV btw), values would look different if you charged up to 100% and it went through it's battery balancing thing at the end... not sure if this valid or also a thing with Lucid?

So the starting/new battery capacity is 88kW or 92kW ? I've seen BOTH referenced but I always thought NEW was 88 on the Touring or Pure? Am I mistaken?

Even that’s been debated. The consensus is 92kW, but you can find articles that state 88 for the Pure AWD & Touring. Some think the 88 refers to a buffer, with the 92 being the actual capacity even if it’s not all available to the owner. Would I bet my life on either number, nope.

In the early days, this was true. Nowadays, its been figured out to 88 for the Pure RWD and 92 for the AWD, which I'm 99 percent sure of.

I guess this means I've lost 5kW capacity already and approximately 5% despite being only 7 months old with 7275 miles having a 2023 Pure AWD

Just remember that battery capacity loss is the worst in the first 2 years and then tapers off after that.

oh okay. I was slightly worried I was doing something wrong but I rarely charge above 85% and almost never gone below 20% SOC so I couldn't figure out what I might be doing wrong
