How Much Range Are You Actually Getting?

I'm perplexed. My charging number data does not make sense AT ALL with the reported car efficiency numbers. I'm getting about a 22% error with the calculations. Based on car display numbers, it would indicate that the battery size is only 91-92 kWh. If that were the case both the car and my numbers would agree.

Is it possible that Lucid is software limiting the battery usage to only ~80% of the 112 kWh for the first 2500 or so miles?

That would make the observed range agree with the reported efficiency. The battery people are supposed to talk to me tomorrow since I have a lot of questions about what is going on. It is either that, or the software has a big bug in it or I have some major error in my calculations.

Curious what the Battery guy says. The only thing i have heard is that the motors break in over the first 2k miles and that effects range but Agee that should not impact your calculations. Note some energy loss may occur when car is not actually moving because Batteries and cooling system are “on” even when car is locked.

Yes. I see a 10% transmission loss from what is delivered with my calculations. If the battery size is limited, then I am seeing a 25% loss through heat and BMS fans. Our garage is generally in the 70’s, but does warm to the mid 80’s overnight when charging and the BMS fans are running.

There is also the 3% loss after home charging. charging to 80% never results in 80% Unless one drives immediately after. Within 2-3 hours, the car consumes 3-4% of the battery and I start the day at 76-77%.

I have been wondering the same thing. Some EV makers are reserving part of the battery to conserve battery life. I understand that but does that mean that we don't have to only charge to 80% most of the time because the remaining 20% is already accounted for? And if the maker reserves 10% (I believe that is what BMW is doing), does that mean we can normally charge to 90%?

I think all automakers “lock out” with software some amount of battery capacity at both top and bottom end for longevity reasons. Some publish both actual and usable kWh figures but many only divulge the usable.

I doubt Lucid is locking out additional capacity for the first few thousand miles, without disclosing that fact. If they were delivering cars with a usable capacity set lower than the usable capacity used for EPA range figures that would be an issue.

I agree and sure hope not because they suggested I keep my range to Max 90% and not below 10% so THAT 10% to me is reserve.

So when fully charged it shows me 468 Miles and yes it loses 3-5 Miles every day just sitting in my garage. Texas is Hot and even with temperatures in 100’s I have not heard the fans come on.

I do not keep it hooked to the charger because that did result in charging every so often and made the fan come on.

The Range is the Range. I am no longer bothered about it BUT It would be nice to know a ballpark range one could get at any time. So If I start with my 468 miles and go long distance will I at least get 300 miles as a worst case scenario or not.

Same if I start with 350 miles range and same as above would it give me the same ratio or would that be something different.

So what is the best practice when in the garage? I was under the impression that even plugged in you can set a max limit via Lucid app or charger (Ie juicebox) app?

I just have the charger and a regular 14-50 NEMA Swtich. The car is set to 90-10 as suggested by the DA and I have not changed it. That is why at the max 90% level it shows me 468 Miles which is roughly 90% of 520 EPA MAX Range for my GT “Range” version. There are smarter folks than me who have had the car much longer who have posted about the charging. May want to check it out.

You have a cool garage, my Lucid gauge says 90F sitting inside garage in 10am.

I have a hot garage mainly bc it has huge arch window facing north garage door facing west. I am thinking about getting radiator sheathing to tape behind my garage door and strong tint my window and/or cover up with window treatment.

Yes, you can set limit via Lucid car or a wall charger device. I think best practice is not to be plugged in all the time. Once plugged in, that mysterious Wunderbox start fanning frequently with mind of its own. It’s best let the car sleep whenever necessary. This car has monster battery, no need be plugged all the time, imo will last longer than other smaller capacity EV over years.

Do you have 19” tires?

 

[STOCKacts]

I am hearing from a lot of owners that they are getting no where near the estimated range published on the Lucid Motors site. I know this is not uncommon of any EV, including Tesla. But I am curious what range you are actually getting with your "normal" driving - however you normally drive

I opted for 21s. I wonder if I should have chosen the 19s. I guess I will absolutely need the 19s for road trips. At least they will be for sale with tires from Lucid.

Interesting idea. Any info on the cost? What sort of tape would you use to hold up the sheathing? It’d be a simple heat barrier.

This is how my last home garage look like. My wife did it. She ordered for our home contractor to put on for $100+ cost, $150 labor.

That‘s inexpensive! Looks like a nice job, too.
I’ve also seen insulation foam used for garage doors.

Once the car has enough miles on it, and as you learn to drive it, you can get 90-95% of the range.

My last garage door cracked from all the twisting of opening and closing for more than 20 years. So for reasons of strength and temperature control, I had the replacement installed with insulation (thick white insulation). But here in the summer in Scottsdale, it still gets into the 90s and I don't have my Lucid yet (charging my BMW 530e in the garage doesn't seem to generate a lot of heat but I do hear the car cooling system come on and off to keep the battery pack cool.

Yes, I do have 19” tires. I don’t think my garage is cool. I believe it is still in the 90’s there but I do have foam in the door and 4 small windows on the garage door that faces North.

I believe not leaving it plugged in and letting it sleep helps and don’t have the audible alarm on that is part of the settings.

Yeah my 20 year old garage does have Foam Insulation on the inside but you can buy the sheets at Home Depot and get someone to glue them on the inside.

Better yet, do the sheathing first and then the foam.

It was $100, a few years ago, now slightly higher with inflation.
