99% then it stops

Can’t seem
To get to 100% charging

Would preconditioning help ?

gravity is 1 year old

More or less you get 100% when the car measures. Then it rebalances to 99%, or you turn on the car with it immediately dropping to 99%.

That just means it is somewhere between 99% and 100%. It may be at 99.9999% and still show 99% only.

Don’t worry about 99% versus 100%. Batteries don’t really have a 100% charge state. The BMS sets a 100% threshold and it asymptotically charges to 100%. Reaching 100% would take infinite time.

Lucid could update the BMS to display 100%, but it wouldn’t change the underlying physics in the battery.

Note that letting the (NMP) battery sit at 100% causes faster battery degradation. It’s OK to occasionally charge to 100% and then immediately drive, but for normal use, stay within the daily charge range.

As others have said, it’s the same with other EVs. You might get it to 100% but it drops off to 99% in less than a mile or won’t say 100%. Your car and battery are still good.

We used to be happy with "Full" and "Empty", with a few bars in between!

Another factor, comparing the percentage shown on the car’s screen and app (integers) vs. what the API reports (1 decimal place) - it’s evident that the end user-facing interfaces round down, probably as a safety margin. It might underestimate by 1kWh at most (a few miles).

The trade off is it feels like the car is using more energy than it should (e.g. charge to 80% and then it immediately drops to 79%), or that it stops short of the charge limit.
