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

I’d vote for a bms throttle back due to temperature. Too bad we don’t have those data.

Someone at some point someone will put a real monitor on it and well see the cell variance and that will tell us if its the whole pack or a cell to cell variance issues which is what it usually ends up being.

I hope GM can fix this with a software upgrade, but Im going to guess they are having a hard time with cell to cell variance.

At that low of SOC the bms can pull the high cells back and let the others push up through a faster charge rate relatively. They would need to be pretty far off to justify pulling that hard back.

I2R on the other hand…

400V is old technology and is not able to keep pace with 800V architecture. Congrats to GM for coming out with circa 2013 architecture in 2023, lol

I've been saying this for the past several years but the Tesla yuppies on this forum swear that 800v architecture isn't any better.

When you include the available charging network in some areas 800V is near useless. I couldn't use 800V to its full potential in my area because there are so few chargers that are more than 50kW and I have 3x as many Tesla chargers available as every other type of charger combined.

It should be better. In application here I'd be sitting a long time to charge unless I had a proper charging, but it's mostly rural Midwest and Tesla spent their money to spread chargers around and it's obviously paid off or I'm sure I wouldn't see many Teslas here. Its probably why I don't see too many others. According to Plug Share there's only 4 350kW charger locations in my state. A 5th one is listed as not online yet.

It COULD be better. It's better in theory.

It hasn't shown itself to be deliver shorter trip times, or be faster on the track in terms of Plaid vs Taycan and their times around the ring.

800 Volt cars dont deliver universally higher MPKWH.

If doesn't actually deliver better efficiency, shorter trip times, and faster lap times - then how exactly is it better?

 

[Ws6]

@Ws6, is the EV6 GT still the new best car ever?

Any minuses?

The range could be better, it could be faster, it could cost less, I mean, nothing is perfect.

My only real complaint: the cabin pressure relief vents rattle over rough pavement. This is normal for an ev6, and the brand new ev6 wind loaner I had while they diagnosed that, did it, too.

Everything else?

-I was told it got 206mi. It actually gets 240mi on my typical route.

-I was told it did 0-60 in 3.4 seconds. Ive timed it at 3.28 seconds.

It just flat out delivers. For the price point, I can't think of anything EV Id rather have.

I know my ev6 gt does not fall on its face at low state of charge. Here is a 1/4 mile pass at 85% SoC roughly, and one at 35%. Not bad at all. Lets see what a M3P pulls in the quarter at 35%.

It would be interesting to see what the hit might be.

We know the Plaid smoked the Taycan around the ring so we know that the 800V architecture didnt make a difference there.

800V is better than 400V because it enables faster charging speeds without adding heat and requiring new cables and electronic components. By doubling the voltage flowing to the battery, we enable twice the charging speeds while halving the current, and it is the current that adds heat.

(as of today) None of that results in a faster trip time, lap time, or greater efficiency.

 

[UncleDave]

This owner has had that dip too. But also other charging sessions without it. Sounds like it might depend on many factors, like charging any other car. The charger itself, temperature, preconditioning status, etc.

Hopefully more test soon.

Id bet the guys at Honda are more than little worried about this having hitched up to the same horse.

GM needs to get this together and soon.

Then why aren't the 800 volt cars, actually faster and more efficient ?

I NEED a Model 3 Highland Performance so I can make all the exotics in town lives miserable. Hopefully the acceleration will be even better than the current car, which is already an 11.5 second qtr mile car.

You are not making any exotic miserable with that car. People that own exotics rarely thrash them and could buy an ev car yesterday if they felt like it. They have sex on wheels and are not concerned with some geezer in a family coach.

He is one of the reasons I can't stand Tesla owners. They think they are hot stuff. Lucids eat Teslas for lunch in performance. I don't see them rearing their mouths about "killing exotics " or "making them miserable ". Ferraris Lamborghinis, Paganis are way cooler than the "highland" or whatever junk musk proposes next. By the way I said this 5 years ago. Tesla needs to build out their charging infrastructure for their semis even though they are late. Well guess who wants the Government to cover their semi charging stations? Tesla. Musk "claims" he's against subsidies but oh now they're behind and don't have chargers. So the tax payers should foot the bill. I'd like a bill to kick him out of the USA back to South Africa.

Well, in my case I am a fiscal conservative. The performance for a Model 3 Performance is amazing. For around $50K, you get an 11 second car.
Contrary to what @Trav thinks, the people around here drive their exotics. And we do have a little fun, within reason. A sedan that can mess with the gorgeous exotics is a lotta fun. For both of us...

It is kinda sad how people act like cry babies around cars they don't like. It's just a car; it ain't that big a deal. This is a EV section of the forum, right? Personally I like all kinds of cars, but that's just me.

By the way, there are several Teslas (and Bolts) on my street. We are all a little different but have found these cars to be wonderful.
The family across the street have a MBZ AMG roadster with an incredible sound and a Model Y Performance.

...because every single tesla owner is the same after all.......

On chargers...

If musk is behind then who is actually in the lead?

Im data driven.

I've posted lots of 3rd party data comparing 400 and 800V cars.

Ive seen no 3rd party data from anyone here that refutes this.

No you are not. You keep quoting Bjorns observations. Those are not repeatable, they are not under the same conditions, they are not even run in the same country. Your ”Data” is only how you like to see it.
