From the article: The Tesla Cybertruck is finally starting to leverage its 800V architecture, thanks to the rollout of upgraded 325 kW charging at select V4 Supercharger stations. The boosted Supercharger speeds are only available at select V4 Supercharger posts in the US, ahead of a wider expansion next year alongside upgraded Supercharger hardware. According to a post from Tesla Charging on X, the company has opened up nineteen V4 Supercharger locations to deliver 325 kW to the Cybertruck, the only Tesla vehicle with 800V architecture, offering faster charging compared to previous 250 kW peak at V3 and V4 stations. Early tests reveal that while the 325kW is an improvement over the peak 250 kW that Cybertruck owners have experienced up to this point, the charging curve of the 4680 battery cells, which has been an issue in the Model Y, still needs some upgrades. One Cybertruck owner reported a peak charging rate near the promised 325 kW at a low state of charge (SoC), but the charging rate dropped significantly after that. The Cybertruck’s battery took 10 minutes to go from 8% to 40%, but then took another 25 minutes to reach 80%, leading to a 35-minute session to reach 80%, not much faster than at 250 kW stations. In comparison, other EVs like Hyundai and Kia, which also utilize 800V systems in the IONIQ 5 and EV6 respectively, sustain higher rates for longer, enabling 10-80% charges in around 20 minutes on 350 kW chargers.

I didn’t see how it’s reaching 325 kW. Since v4 cabinets aren’t out yet, is it increasing the amperage to get to 325 kW?

The v3 cabnets are 400v, v4 are 800v, more voltage rather than amps

Yes. Current "V4" superchargers are V4 post with V3.5 cabinets which still only use 400 volts hardware. To achieve 325 kW, they are pulling like 900 amps to the trucks.

He's asking how V3 is able to do 325 kW now, instead of the 250 kW it was doing before. My understanding is that it is a higher amperage.

Ye OutOfSpec mentioned that the V3 cabinets actually can go higher than they report to 600 amps or something like that

Kyle Conner just peed a little.

Here comes a 45 minute video!


500kw wtf

At least one location should be out, based on what Tesla has been posting on X.

You can get three fleet trucks for one of these as a work truck. Select locations does not mean road tripping. Would work if CT was $39k, but it's not.

Meanwhile most people are stuck in BFE doing 65kW because Tesla won’t upgrade their gen 1 chargers on major routes.

Currently the 3rd best selling EV in North America. Not much of a joke now is it.

Tesla announced the new V4 1000V cabinets but said the first charger with them would come online next year.

My understanding is this is just an increase in the peak current output at stations with V3 cabinets, specifically those with V4 pedestals/cables which are a bit beefier.

I’m guess they will see a boost at the non-Tesla 350kw chargers.

Lol, I bet he is driving to one now. Looks like Lamoni, IA is the closest.

What does the charging curve actually look like on these? If it’s not pulling peak for that long, how much time will this take odd a 20-80 run?

Yes, here is a V3 cabinet sticker: the important part is on the right under “POST DC Output” https://imgur.com/pQVa1qP Technically outputs up to 500V 631A, but probably reliably 400V at around 631 amps. Maybe with additional testing, and less power sharing to other stalls, the cabinet can reliably deliver closer to 500V, Although that would only be 315.5kW charging. I guess there’s a chance they’re pushing the amps harder if it can (and temps remain sane). It could also be pulling more power from other cabinets since they all PowerShare.

Does the Find Us map show these V4 chargers and their maximum kW? Are “actual” V4 chargers even deployed anywhere in the states?

“325kW at select v4 stations” v3 max is 250    Read carefully

No, it's 325 kW at stations with V4 dispensers and V3 cabinets. The question was about how they're able to do 325 kW with V3 cabinets.

He's been getting 325+ kW charging his cybertruck at EA.

Sweet so you can charge up to that 500 miles of range they promised right?

Oh wow that's a pretty short video. ;) (...for Kyle lol..)

Did they really expect 0-80 to be the same on a larger battery pack when it’s receiving the same current? That makes no sense.

long consist fly degree merciful uppity ripe innocent abounding continue *This post was mass deleted and anonymized with [Redact](https://redact.dev/home)*

Yeah I mean the CT has what, a \~50% bigger battery than the Ioniq 5 and we're supposed to gloss over that?

19 locations to be precise

Salt Lake City to Oregon has such stops.

lol why are his videos all so long?

Tesla doesn't have any gen 1 Superchargers operational anymore - they were all upgraded to V2 when those rolled out. You may be referring to V2 or Urban superchargers. Tesla has typically added stalls or stations instead of upgrading V2 unites.

I want to say the V4 posts have the new liquid cooler cables where the copper is immersed in water instead of just a water pipe next to the copper. This likely enables the higher amperage even from the 400v cabinets?

YT Ad revenue and recommendation probably.

I don’t think he’ll be too excited about the charge curve still, considering he was looking for 300kW+ at 60% SOC in the recent Taycan cannonball attempt

I believe that is true, yes.

Here I am happy to hit 100kW with my model 3 LFP lol

Great how about better range and towing now

I’d love to hear more about charging curve improvement across the board for all models. It’s been a while since we’ve had one of those.

Simple. More amps. You do not need a v4 cabinet Right now the CT does 725 amps max this will go to around 825 amps on current equipment. Tesla always does more amps.

Tbh you don’t hit super high charging speeds for very long. There’s not a huge difference in preconditioning and hitting 65kw all the way up to 85% vs having a small bump on the lower end of the soc IF your battery is sufficiently heated, and often they’re not. Improving the charging curve would be much better.

Actual v4 cabinets are supposed to be released next year in January?

Exactly, which is why I don’t understand this demand and urge for faster speeds. Charging curve is much more important. I’d rather have the car be able to maintain 10kw more charging speed for 30% of its charging than hitting a really high charging speed for a couple mins. Would also degrade the batteries FAR less. But for the cybertruck and preparation for the semi, I get it.

Would be nice if the lfp got a charging curve improvement but I suspect the R&D for all things lfp are on hold as they no longer sell in the US and the focus is on the future

Source for January? Tesla release states sites are currently being permitted and sites opening in 2025. That's 12 month window. https://x.com/TeslaCharging/status/1857133221538148638

He gets paid by the minute

Failure to edit.

Yeah I agree. Just sucks feeling a bit left behind even though my car is a 2022. I’ve never once gotten the max charging speeds of 170 kW. I think the most I’ve ever seen after like 45 mins of preconditioning on the highway was like 130

Hitting 170kw isn’t about preconditioning only, you have to be fully preconditioned AND at very low SOC… like 10% or below… and you’ll hit 170kw for maybe a minute and it starts to slow down progressively from there. Even charging at 15-20% means you’re not going to hit those max numbers. Try going to a supercharger with very very low SOC. I usually don’t risk this when I’m on road trips or something because I want more of a cushion. I’m normally the person that’s arriving with 15%-20ish

For the 4 chargers across the US

Cause the man is excited to talk about cars so much. I genuinely love that he’s so excited

I’m not following your logic. What matters is how many miles of range you add per minute of charge. With your logic, manufacturers would benefit from just putting in the smallest battery packs possible, and then they could have a slower charge time?

I’m making the point that 80% in a 100 kWh pack is not the same as 80% in a 70 kWh pack. So for the article to claim the cybertruck was slower is wrong. They should’ve tested kWhs charged not percentages because these vehicles are not the same.

With that logic a Tesla semi should be able to charge at a sustained 350 kW and hit 80% at the same time as an Ioniq 5.

> I’m making the point that 80% in a 100 kWh pack is not the same as 80% in a 70 kWh pack. It is as far as the C rate of the cells goes. If you add more cells you should be able to charge at a higher kW rate, provided the charger can output the power, the pack can keep the cells cool enough, and there are no other bottlenecks.

It should be able to hit 80% in the same time as an Ioniq 5 given enough charging power, and given that the individual battery cells have similar C rates for charging. For the Semi with its ~900kWh pack a 10-80% charge would be about 630kWh. Delivered in 18 minutes that would be an average charge rate of 2.1MW. You'd need a charger capable of that output, a cable that can carry it, and a battery pack with enough thermal dissipation to keep the cells cool.

With a 50% larger capacity you would expect about 50% higher charge rates. That’s how battery cells work. The 10-80% charge time of a pack should stay about the same as you add cells, since the bottleneck is the rate at which the individual cell can be charged. To maintain that though you need a charger with enough output, a cable that can carry it, and a pack with good enough thermal management to dissipate the generated heat.

How many times did he rapidly part his hair after reading this?

This article is based on a 325-350 kW charger. You are adding a variable that is not in the mix. Their statement that a cybertruck was outperformed by a Hyundai is disingenuous.

If the Cybertruck had a charging curve, relative to its pack size, similar to the Hyundai or even other Tesla models then it should have maxed out that 350kW charger and maintained a higher charge curve throughout the session. The test they linked to shows charging dropping below 200kW before 40% SoC. So far its performance is less than we should expect for its pack size. At over 50% larger pack capacity than a long range Model 3 or Model Y, we'd expect a peak charge rate over 350kW and maintaining over 200kW past 50%. Some of this is likely Tesla being conservative. They are newer cells with less field experience, and Tesla hasn't had its own 800V chargers to really push things yet. There might also be limitations of the current generation of Tesla cells and pack cooling.

lots of details. he packs the most information into his videos

325 kW - Garage Burner 500 kW - House Burner

Out of Spec managed to get their cybertruck to charge at 300+ kw using a janky CCS to NACS adapter at an EA 350kw station.

This is great and all but Tesla battery charge curve sucks. It’ll drop off significantly at 30%

I wonder if his wife just tunes him out at home.

Correct, the original Audi etron still has a competitive charge time despite only a max of 150kW.

Wow, downvoted? I can’t be the only one that reserved based on those initial numbers and is jaded that not only the price skyrocketed, but the mileage specs cratered. No way I could justify that purchase at the current prices. Now with 500 miles range, maybe if I’m feeling reckless with my finances. Have an upvote.

Thank you! Same here. Went to Silverado EV

Beyond a one-minute video, it takes way more effort to make effort to make a 6 minute video than a 60 minute one Hence why podcasts or interview shows are quite lengthy. It's simply easier to just do it raw than edit

Don’t think that’s gonna help sales.

So does the Ford F150 lightning

It’s a 10 minute threshold. His videos bring 45-60 are just because he’s very in depth

Thermal and chemistry limited. They can't do much more with sacrificing long term battery usage and safety

I mean supercharging in general sacrifices long term usage so we might as well get a better charging curve

I suppose but honestly the most in can be improved is maybe a few minutes from 10-80%. Not sure how much that really matters since most people rarely road trip often. If you are doing road trips often then maybe an LFP base model isn't the one to buy 😅.

Lfp would be the most resistant to degradation from supercharging so def a trade off with range. Considering 10-80% is 25 mins, you’d probably be looking at more than a few mins less if you can maintain better speeds across the curve. Even then, 2-3 min reduction is still 10% less charging time. If you’ve ever seen supercharger lines in NY, that would be a huge improvement lol.
