Home Charging vs. Electrify America

[hmp10]

So now I'm wondering if this OTA has occurred or is it part of the upcoming 2.0 update?? Also, I'm curious if this coming update will increase or decrease the potential damage to the battery of fast charging??

I doubt if a software update can do anything to change the way a battery's chemistry and structure react to heat from charging.

I suspect that Lucid programmed a conservative charging curve into the early cars in order to gain some experience with how well the batteries stand up to fast charging in real-world use. If data show that the batteries are holding up well, Lucid can move to a more aggressive charge curve through an OTA update and see how that goes over time. This is the approach Tesla has been taking whenever it releases a new battery pack, and I think it makes a lot of sense.

If you care about the battery, you will never use a DCFC...but generally speaking yes, the faster you charge the worse it is for the battery because of heat.

Seriously? I had no idea that DCFC was bad for the battery. I assumed that you are good if you just charge yo 80%. I love this forum (most of the time).

I do understand the concerns about excessive heat associated with fast charging, but it seems to me Lucid specifically chose to use a 900 volt system to help with fast charging. Not sure why they would facilitate something that is inherently bad for the battery??

The 924-volt system does help reduce heat in charging, but battery chemistry also plays a role. Lucid uses Samsung batteries in their 118-kWh pack (for their highest-performance cars) and LG Chem batteries for the 112-kWh pack. At the time Lucid announced the use of Samsung batteries, they said they had worked with Samsung to develop a proprietary battery with greater resistance to damage from fast charging. They made no such claim two years later when they announced that they were also going to use LG Chem batteries. Instead, that announcement said Lucid had worked to match its car optimally to the characteristics of the LG Chem batteries, implying the LG Chem batteries were not proprietary for the Lucid application.

I think "inherently bad for the battery" is a matter of degree. Fast charging, even at higher voltages, will degrade any lithium ion battery faster with current technology. In one of his interviews, Rawlinson even made a passing reference to the greater stress that fast charging will put on the batteries. However, the difference will almost certainly be marginal over the lifetime of the pack for people who take reasonable precautions, such as not repeatedly charging to 100% and letting the pack sit for prolonged periods at full charge, not letting the charge dip too low repeatedly, and not using DC fast charging when not necessary for road tripping or when a L2 charger (and the time to use it) is available.

I think you do have an account that Lucid set up for you. When I use an EA charger, I get a receipt texted to me on my cell phone, and I never signed up with EA myself or gave them my cell phone number.

Same here.

If you haven't seen this test, you should read it to answer your question. Charging at 350kw only gains you about 6 min. of time over a 150kw, and only below 50kwh charge. If 6 min. means that much to you then go ahead. But as others have noted, you risk heat damage to the battery and increased cooling energy to keep the battery from overheating. Remember, Heat Kills!

Lucid Air Dream Edition Fast Charging Comparison: 350 kW vs 150 kW

We charge a 2022 Lucid Air Dream Edition from zero to 100% on both a 150 kW and a 350 kW DC fast charger and analyze the differences.

Will stick with the 150kw charger then.

I’m on the fence about going out of my way to charge at EA. I just got a PGE bill for $1,000, so I’m now heavily invested in getting solar. I’m also going to make a few changes that will help bring my bill down, but I do not want to change my life style, which is why I’ll invest in solar. I really like to run my AC, which PGE considers a crime against humanity. Lol

I’ll probably charge at EA once a week if I’m in the area of a charger. After my panels are installed I probably won’t.

I’m in the same situation, which is why I’m getting solar too. Besides, there is 26% Fed Tax credit on solar for 2022. Along with AGT 7500, I want to reduce these tax liability before the incentives are gone.

Good God, no that should be Bad God. You must live in a 50,000 sq ft house!. We live up here in Blaine, WA , in 3400 sq ft house and my electric bill was $74 for August. Granted, all our power come from hydroelectric dams and our rate is really cheap but still...a $1000? Glad we move up here from Dana Point....

I don’t, but apparently I use enough energy to power a house like that. PGE is a nightmare of a company if you don’t confirm to their usage. I’m a perfect solar candidate.

Have you chosen a company yet? If so, who and why?

Have you chosen a company yet? If so, who and why?

I use a local prestige boutique company called Blue Raven Solar which was acquired by SunPower.

I chose them because SunPower has highest national rating over SunRun/Costco and Tesla Power and longest business history. Their equipments may be more expensive, but they have longest warranty, commercial grade micro-inverter, least deterioration life and great service. So I thought it was worth to pay more.

Lucid recommends 80% and to have it plugged into the charger when the car is not in use. I have the Autel Maxicharger wall charger and it is awesome with lots of options. Very nice app, long chord and you can program RFID cards to give to others in your house hold that or friends that have EV and need to charge when they come over.

Which Autel Maxicharger do you have, the 40 or the 50? I only have the 50A service to the NEMA 14-50 plug in my garage (so max 40A output). Would it make a difference in safety/stability having the more compact model which plugs in to the NEMA 14-50 outlet vs having the charger hardwired and having a separate holster? How long have you had the charger (just since you received your Lucid or did you use it for a prior EV also)? Any issues or drawbacks? Since I have Off-peak charging rates, I want to make sure that I can set both the start and stop times. (Tesla only allowed a start time or a departure time, which I wasn't a fan of.) Thanks in advance.

That’s a great reason. For some reason Sun Power quoted me for the 370 watt U series because they can’t get the 420-440 M series. I may have to go with a smaller outfit if they can’t get the more efficient M series.

When I got my solar put in, SunRun was 15k more expensive for inferior equipment.

That’s good to know. I’m getting my bid this week.

I've been very happy with Chargepoint Home Flex's charging window approach. Much better for me than a programmable start or stop time.

Some of this may be due to recent fuel cost surcharges. Our power provider in south Florida generates power with solar, nuclear, and natural gas. We are at the lower end of utility rates nationwide, and we have never had a monthly bill hit $500, even when charging two EV's. Two months ago the bills started topping $600 due to "temporary" fuel surcharges even though domestic natural gas is the only fossil fuel our utility company uses.

3749 sqft in Cupertino, PGE bill of $700-800/mo before I got solar. It’s absurd here.

Got Sunpower and Tesla Powerwalls, have been extremely happy with both. (But I have the 400W-410W panels)

I’m in the same boat in the North Bay. It’s nuts. When did you get your panels? The lady I’m dealing with says she can’t get the 400+ panels but I’m a little skeptical.

PTO in August 2021 or so; I can’t recall exactly. High high high recommendations for Cobalt Power. If you want I can give you the contact info for my guy; he was great and we still talk regularly.
