Some odds and ends

Yea, I'm not sure why Lucid keep the car in such a deep sleep state all the time compared to other EVs for that matter. It probably could be fixed with software updates. But there has to be some middle ground on how and why it's implemented this way for now and how to improve it.

Clearly it can't be to reserve power

Yea thats my point too! There is some phantom drain, not a HUGE amount but every night you are losing charge for what though? Everytime I get in the car, it's booting from cold and everytime I open the app it has to wake up?

Tesla had problems killing the 12 V batteries due to the high number of charge/discharge cycles needed to keep the car awake. Tesla Switched to a Lithium Ion 12 volt. I would be shocked if Lucid is not using a similar system as the problem is well known in the industry.

How about using the 112kWh battery to keep 12v charged, can't be that hard to do!

That is what BMW does on its PHEVs (and I assume on its BEVs but I don't know for sure).

All EVs do that through a dc to dc converter. The problem is that Lead Acid batteries do not like constant discharge/charge cycles and fail prematurely.

Li-ion?

 

[MikeTz]

Li-ion?

Tesla's 12 volt 6.9 Ah Li-ion pack. Very small by automotive standards but gets constantly replenished from the HV battery pack.

So did we know what type of 12v battery the Air has? Where is it?

 

[hydbob]

It has 2, one in the front and one in the back

Lithium or Lead Acid?

Whoa, two batteries and the car goes into sleep mode. Yeah, software needs an update. A laptop can run for hours on a far smaller battery.

 

[hydbob]

Lithium or Lead Acid?

Hmm the rear one is easy to access front not so much. Let me try tomorrow when service comes to take my car, again...4th time now

Here's a picture, maybe someone can decipher.

I used to use "Deep Cycle" batteries on my bass boat for my electric motor. The ones I had were Lead Acid but that was a long time ago.

It says ‘danger/poison’ which makes me think it’s lead acid.

 

[Adnillien]

All of the batteries on their web site are lead acid, either AGM or VRLA. I beleive this is VRLA.

 

[hydbob]

So this is a bad thing? Someone tell me how I'm supposed to feel!

 

[Lucken]

Hydbob, my impression is that Li-ion is the superior tech, but lead acid is cheaper. Many Tesla owners switched over to Lithium when their 12v batteries died before Tesla switched over themselves in some, if not all models. Tesla owners got tired of replacing their lead acid batteries and having their cars DOA. With that said I don’t know what other EV makers are using, especially in newer EVs.

Wouldn't an equivalent Li-ion battery weigh less? I guess there's the first hack.
