The Lyrics charge curve is in and......

We will have to agree to disagree. I say take it for what it's worth. New and better science always trumps prior science. We can only deal with the best science we have.

No one is saying it is perfect, but I can say Nyland does pretty well with the tools he has. He always supports his numbers with conditions in effect at the time of the test.
Where I struggle with your point is the term "proven". I had a career in data capture and analytics on that data. I tell people the results are as good as I can get until they are not. That's the nature of science.

I have learned to be willing to challenge even my deepest beliefs.
I get it. When the information supports your point of view it’s good. We are not discussing science here. What is being discussed is point of view being passed off as facts,
 
If 800 volt architecture makes for superior drivetrain efficiency I'm having a hard time finding it.

The EPA has an interesting comparative section that lets you compare MPGE and a host of other specs - I didnt know the EV6 was categorized as a wagon - thats interesting. I use the EV'6 and 800 Volt benchmark most but did a high end car comparison.


Im open to looking at more data. Who has it?

Much of this pretty close to what we see in other 3rd party testing making the EPA's data -- https://en.wikipedia.org/wiki/Corroborating_evidence

Back to the topic.

I think another YouTube person saw this same weird charging sag around the 80% mark. Seems like there is something going on in the battery management system that is causing this fluke. Curious to see this play out and someone analyze the battery stats when these sags occur.

Not hugely terrible charging performance but not great from GM's top brand riding on their Ultium platform.

As soon as someone gets an OBD monitor on one and charges from a low SOC on a hot day at a DC fast charger were going to see just how well the general controls cell to cell voltage and temps.

Also eager to find out how well it cools the cabin when fast charging in 110 degree heat.

Hopefully they are just being conservative and can safely turn it up from here because based on what we've seen so far this is just a nice coach and not at all a competitive EV from a multi stop trip standpoint.
 
Looks like they possibly improved the charging curve with a software update a few weeks ago.

No huge dips like before. Need to see more sessions though.

This is someone on CadillacForums.com

~33 minutes from 24% to 85%

Looks better.

Did they say if HVAC was on or off?

Can you link to it? Thanks.
 
Never mind we're using the same source

Looks like cooling issues.

Heres the curve from the lyric forum with the latest patch/ update - still a giant dip.

GM has a ton of work to do, and they've had a ton of time to get this righted optimize this, but here we are.

This does not bode well for the blazer.

Well, we are finally seeing higher mileage ev6 battery degradation data. People with 100k+ miles are reporting zero functional loss, but so far the highest mileage official data Ive seen was at 75k miles and showed 4% degradation, although the owner stated they mever fast charged past 80%, so this indicates a fast charged sometimes vehicle that was well cared for. Still, 4% in 75k miles seems plenty good.
 
Still waiting for the big boys to get in... My guess is the GMs of the world have their customer loyalty but their tech struggles...
I mean, the big boys are in? Tesla has nacs...and soon so will everyone else...which leaves what reason to have to own a Tesla to get into EV?

Price. The Model Y is cheaper than all the other EV SUVs out there. And the 3 is basically cheaper than anything but a Bolt which maxes out at 50Kw DCFC or useless Leaf.
 
Okay. Me, on a recent road trip:
12-90% of a 77.4kwh battery. 24 minutes. I guess if I wanted to go 1/3 slower I could have bought an old Tesla.

The Hyundai and the Tesla are pretty close, looks like the nod goes to the Hyundai in most cases - but not by much considering the Tesla is about 25% more efficient.

HVAC in the heat is the wildcard between these two.

Now that Hyundai is on NACS Im eager to see how well they can get it working, If they can get it close it'd put one in the running for me.
Im still concerned we don't know what degradation looks like, but we'll see in a year or so.


On the Ultium Caddy - It's just really sad after all this time, taxpayer loan money, and considering the relative size of the caddy battery is 20% or bigger this thing should blast in amperage right up there with the best of them.

I suspect its got an intercell cooling problem that causing it to pull back- its pretty clear its thermal in nature, but where is the bottleneck?

After a year + of tweaking and software changes to be at this place and time, it's looking like a redesign for the GM battery.

efficiency, price, ease of use.

Still the only EV I could put my parents in for a road trip.

Love to see these if you have the links, Im always interested in this data from everyone.

Thanks sir...

Is it really, though?

Edmunds managed 238 miles of real world range in their EV6 GT, 283 miles in their GT Line EV6 AWD, and 323 in their Wind RWD.
I personally managed 250-255 miles in my own EV6 GT on my daily commute, which is more highway biased than Edmunds.

In their Model Y Performance, Edmunds managed 263 miles, in their MY LR Dual Motor, 317mi.

So we compare the GT and the MYP. The GT has about 100hp more, and manages 90% of the MYP's range while vastly out-accelerating, and out handling it.

Then we compare the MY LR to the Gt Line. It manages to be about 11% less efficient.

So your numbers are about 2.5x worse than reality, where the Tesla is only 10-12% more efficient.

2023 Tesla Model Y/Cargo volume
30.2 ft³, 76 to 76.2 ft³ with seat area

2024 Kia EV6/Cargo volume
24.4 ft³, 50.2 ft³ with seat area

2023 Tesla Model 3/Cargo volume
19.8 ft³, 22.9 ft³ with seat area

True, the MY does have more cargo space, putting the EV6 kindof in-between, but more like the MYP than it is the M3.

Here is the link, it's in Dutch.


This is what my car displayed with 100% SoC:
1697664166074.webp


This is what it actually delivered:
1697664188831.webp


Try that in a Tesla. Their range meter is pure trash. Being sued for it, if I recall, lol! And you can easily see that the 206mi rating on this car is not accurate. This was on Michelin Pilot Sport AS4's by the way. 6/32 tread.
