Vacation charging

[MRU]

That’s strange. So what’s the point of keeping it plugged in if it doesn’t resume charging at the 50% threshold? Then I’ll need to keep opening the app for it to begin charging. Will monitor and see how it goes.

It will top up as needed or if scheduled to charge.

That is, if you have a charging schedule set up, it should wake up and charge whenever that kicks in.

If you don’t, it will wake up to take care of itself (too cold, too warm, too low SoC, etc.), if needed, and charge then, but won’t unnecessarily top up.

If you wake it up with the app, it will top up.

Not going to risk it. I’ll just check the app occasionally and hope that prompts the system to top up.

Still not sure the point of keeping it plugged in. I'm getting near the end of my six week vacation here in Palm Desert away from my home in Portland, Oregon. I left my AGT in my garage unplugged in at 80%. After six weeks, including running the last Software Update(1 hour) my car is now at 69%. I fail to see the reason to keep it plugged in even going away for three months at that rate of loss. My wife's BMW i4M50 was unplugged at 80% and after six weeks hers is now at 78%. What am I missing that people and Lucid keep recommending to keep plugged in while going on vacation? I don't see the logic.

I think the bigger question is why is there such a big difference in the phantom drain between the two cars? I’ve noticed the same thing between our former i4 and Lucid and that difference carries over to our current i5 and the Lucid.

Our 2017 MS held the record for the greatest phantom drain of all my EVs, but the rate from day to day was totally unpredictable. The popular theory as to why it varied so much was that it was predicated on when and how long it was communicating with the mothership. Who knows.

It may depend on the temperature of your garage. I'm just guessing that to extend battery life, the car may want to warm the battery in a freezing garage, or cool it in extremely hot temps.

Yes, but a previous poster stated that he left his Lucid at 70% and set to recharge it when it dropped to 50%. It would take about 3 months to drop to the 50% level before the charging took effect. So again, what is the point of plugging it in at all? The plug in would have no effect since it would not drop to 50% during a 3 month time frame.

My Model 3 drains on average 1+ mi/hr if unplugged. Lucid AT is much much better in that. Lucid recommends to keep it plugged in for power/battery management, not sure what they mean by that.

That's one user's experience, one car under a particular set of conditions. In a very hot or very cold garage, the car may need to expend energy cooling or heating the battery.

My daily phantom drain is basically zero at this point now that I live in a temperate climate. I don't understand why most people worry about it.

If I were going away for months, then sure. I imagine I would lose some percentage. But it would likely take more than six months to even come close to draining the car, unless you are storing it in a very cold or warm place.

Try leaving an ICE car out in the cold in Fargo during the winter. See how your battery does.

My Model 3 lost way more battery per day. But that was when I turned on Sentry mode. Without that, the Model 3 was quite good at holding a charge for weeks at a time.

If Air and Gravity ever get some sort of Sentry equivalent, I imagine it would be a similar story. You can't have cameras and sensors turned on 24/7 for nothing.

It never gets colder than 40 degrees in my garage during the winter, so I see no reason to keep the car plugged in while on vacation. Based on what I have seen with phantom drain on my present 6 week vacation, it would take 6 months for my AGT to go from 80% to 36% and that's including running the software upgrades. Unless I hear that 40 degrees is bad for my car, I fail to see why it should be plugged in at all. That 40 degrees is only present some days, most of the days it is warmer inside the garage. Please inform me if what I am saying is incorrect. Yes I get it if the garage is below freezing or the garage is 90 degrees. But barring those extremes, what is the rationale that Lucid and others insist to keep it plugged in whenever you go on an extended vacation?

In your conditions, for 6 weeks, I agree and wouldn't worry about it. But I'm not one of Lucid's battery engineers.
