Vampire Drain

bunnylebowski said:
Interestingly enough my charging session, which I set to daily going from 20% to 80% (I’m assuming Daily should be 80%) finished at 4AM. When I got in the car at 6AM, SOC was 75%, so that was a 5% vampire drain in only 2 hours, which is a lot more than I normally get (usually 1-2%). I did not lock the car with the Fob when I started charging overnight, so I wonder if the vehicle wasn’t appropriately asleep after charge finished. It was 71% SOC when I got to work which fits with my commute, so I’ll keep an eye on it and see what happens in the next 24hr. I did just do the software update so that’s probably gonna add drain to do the update.

That 5% drop lines up with what I see after every session. You shouldnt lose more than a couple miles parked at work now. The worst appears to be over after the first few hours.
 
And here I thought it was my imagination after 1.2.7, the drain start more apparent and frequent. I’m glad there is this forum that we can compare notes.

I got zero drain after doing the software update so that’s new. The car used to run the fans like it was taking off on a runway with software updates but not this time!

I got 1% drain this morning after 1.2.76 installed 🤔
 
I have seen posts on Phantom Battery Drain. When I started tracking mine under 1.2.7, There was a phantom drain, or roughly 1.3 KW per hour. That is huge. I was experimenting on removing the nozzle, leaving it in with the timer on the circuit off. I opened a ticket with Lucid with some difficulty, because I was originally tracking based on mile remaining. That number is an abstraction and cant be used for this purpose. I changed over to % charged, which is more of an absolute. Anyway, I got upgraded to 1.2.75 and started tracking all over. I requested that Lucid's battery team look at what is happening on my car in it's logs. I also asked that they update me as to the findings. I never got an update, but my Power drain over a 26 hour period is 6% now as opposed to 26%, which is still high. I can live with it. Given that there will be some drain, (wireless access, bluetooth sensing for phone, sensing for key fob, etc.) I would expect no more than 60 watts/hour of drain while in idle/sleep mode, or maybe 1.5%. Anyway, the CSRs have a script on this and if you open a ticket, which you should, use % drain, otherwise they will tell you that your car is in calibration mode and the numbers can't be relied on. If they try to tell you that when you are reporting in % remind them that % is not a calibration issue. I had to do that to get any real action.

I am now installing 1.2.76... I hope it finally deals with this.
 
I don’t have my AGT yet. Should arrive in Sept/Oct, so I’m told. However I’m following this battery drain issue.

I’ve experienced similar draining in my Tesla Model X. I’m wondering if it’s better or worse with Lucid.

Thanks

TY for posting your situation. And keep us updated.

If it is sharing back to HQ on those OTA log relay using battery, I don’t mind. I’m just really curious if it is more than that.

I think there is dilemma somewhere. Keep computer on, it drains, keep it fully asleep, people complain boot up too slow and cascade to other issues if drive out too early before system is fully warned up. (Bluetooth, 360 camera, Todal, etc etc)

To put this into perspective, the ORON SOC/CPU in low mode uses 15 Watts. A Laptop with cameras, wireless and Bluetooth on and running the built-in monitor uses 55 watts. The kind of power usage that my Lucid had prior to 1.2.75 makes me think fans are running? I would not expect the Lucid to use as much as a fully fired up laptop for these purposes.

Someone with better understanding can explain this better than me. The car runs on 900v architecture. The PC, BLE and so on should be running on 12v power. There should be negligible drop running this equipment. P = I * V
 
There are 2 sealed AGM batteries running the computers etc. They get charged off the big batteries as needed.
 
Update

Car had completed the charge at 6:55pm

It is now 10:40pm and charging has started again

Just finished again

Car is now dark again

So far 1 hour and 17 minutes of recharge.
 
Oh, I can drive my daughter to school, go to Dunkin Donuts and back home with it still reading 80%. If car wakes up for whatever reason it shouldn't use more energy than to drive it.
