Scheduled charging unreliable

[DeaneG]

I hope you are wrong...

Me too, definitely.

Sorry to have to say this, but I don't think swapping to Lucid's charging station will fix the problem you described. It's the Air's issue with every Level 2 changing station, including Lucid's own.
There is a particular series of steps you can take to get scheduled charging to work most of the time. Maybe someone who knows them can post here.

FWIW, my scheduled charging has always worked fine. You need to ensure that the Tesla charger is not doing the scheduling, and the way that the scheduled charging works is a little confusing, but it does work for me, consistently, and start charging my car after 9pm each night.

I don't have my home charger installed (it arrived today).

If I were to tell the car to start charging at 10pm (to get lower rates) and tell my charger to charge from noon (long before I plug in), until 6am (when lower rates end). Would the car start at 10pm and stop by 6am (assuming I plugged in at 5pm)?

I'm not 100% sure what you're trying to do, but I don't think it'll work. I've found scheduled charging to be 100% reliable as long as the car, and only the car, is doing the scheduling. You can plug in the charger at any time, but using it to schedule causes problems. They only downside is that the car can set a start time but not a stop time.

This will work fine and is how I have my Chargepoint setup.

Trying to have a stop time.

The scheduled charging is for a 12 hour window. Depending on on the state of charge you may complete the charge by 6 am. Multiple your charge rate by 8 hrs to deter the kwhr.

So I get home from work at about 5:30 pm. I plug in my Lucid Air Touring. I immediately get a message on my phone from the Lucid app that says “Charging scheduled”. I have the scheduled charging time set at 8:00 pm when rates go down. However, very often the next morning the car has not charged. It never started to charge. If I go out after 8:00 pm and unplug the car and then plug it back in, it will charge to the set charge limit.

You are lucky. I have had issues with the scheduled charging on both the Lucid home charger (which you cannot schedule on) and the ChargePoint charger with the scheduled charging turned off on the charger. They are sporadic issues, but very real. Sometimes it starts automatically outside the 12 hour window. Sometimes it doesn’t start at all.

I believe you. Just adding my own experience too.

I swapped the old Tesla wall charger for a new Lucid one. The issue has been resolved. I can schedule charge now with no issues.

It looks like my old Tesla charger was too old (2016) and not compatible with Lucid...
I still wish the Lucid software had an "end time" feature in the schedule charging!

Hi…when you did the swap, knowing the Tesla wall charger runs on 48A and the lucid wall mount can support 80 A, did you (A) put in 100 amp breaker and (B))switch to lower gauge copper wires (4-12 AWG down to 2-8AWG)?

I did not make any changes to my breaker box. The Lucid wall unit is set to 50 amp. The breakers were kept at 60 amp rating.
I know that's underutilizing the Lucid unit, but since I charge my car at night when rates are cheaper, it doesn't matter to me.

Definitely depends on driving habits too. Thanks for the response!

Well, another scheduled charging failure last night. The first charge we tried since we updated to 2.6 software on the car. Not sure if it is related. I’m wondering if it is because the car routinely goes offline and is always offline when we are away from the house. Can Lucid fix this scheduled charging? My $25k Leaf always charges. Why won’t my $150k Lucid?

Friendly reminder to all: please stick to the guidelines of not posting the same issue on multiple threads; we want to keep conversations concise so people looking in the future can easily find solutions.

Please discuss here:
Post in thread 'OTA Update 2.6.0'
https://lucidowners.com/threads/ota-update-2-6-0.11212/post-249767

(or we can discuss it in this thread and I’ll delete the other post)

Also, please avoid the strawman of how much whatever car costs. It is not a useful or interesting argument, and inherently flawed; the Lucid does a hundred things the Leaf doesn’t do, and nobody ever said an expensive car must be a superset of all the features of an inexpensive car. This is also in the guidelines.

(There’s nothing wrong with posting your issue, please don’t take this as admonishment for that; just reminding everyone of the guidelines so we can keep the forum on track as it grows)

Weird. I've done 3 scheduled charges at 2.6.0 with no issue.

To answer the question on 2.6 about scheduled charging not working if you stop the charge….

Unrelated to the 2.6 updates I sometimes have to unplug and replug if I get a “cable connected” on the app. It needs to say “charging scheduled”. Sometimes I have to do this several times, or go back into the car, turn it on as if I was driving and then exit the car and plug in the charger cord. Occasionally, the charging will start outside the 12 hour window even though it is set for scheduled charging. I do have to stop the charge with that. I then unplug and replug until I get “scheduled charging.” But if I get scheduled charging, even if I have stopped the charge previously, it will restart within the window. Lucid really needs to work on this piece of their software. Scheduled charging has been and continues to be unreliable and problematic. Again, with my Leaf, I can exit the car, plug it in and forget it. The charging is even scheduled differently for weekdays and weekends as the off-peak times are different. Furthermore, the charge stops when the window closes unlike Lucid. Lucid will continue to charge if you plug it in even 1 minute before the end of the schedule charging window. I would really like to see software improvements in this area.

I had very unreliable charging until I replaced my standard 240 receptacle with an EV 240 receptacle. Since then there has been absolutely no issues. Charging every night as scheduled without a glitch.
