1-80% in 37 minutes 100 kWh added in 41 minutes 1-99% in one hour Rates above 400 kW only held to 3-4% then was very similar to a v3.5 supercharger session afterwards.

Cries in V3-250kWh speed😭
Hope there is an update to the charging curve coming because the improvement in charging speed is lackluster to say the least, especially seeing as it seems almost all the increase in speed is coming from the first 0-5% of charging, which I almost never arrive to a supercharger at that low of charge. A [<3 minute improvement from 0-44%](https://x.com/wmorrill3/status/1972713146344415248?s=46&t=1FL-CLnRodOIjJ9zjhgkLg) is pretty unimpressive
Was anyone actually expecting a dramatic increase? The charge curve already existed. If it were truly capped because of the stall it would’ve been flat at 325 on V4 stalls or 250 on V3 stalls.
Yup exactly. We see with other EVs with much better charging, the curve should stay flat much deeper into the pack. The curve on Cybertruck shows that there are battery limitations to taking in that much power. Watch the Taycan hold 200+ kW until almost 70% or the Lucid Gravity cramming a battery the same size as the Cybertruck 10-80 in almost half the time.
I was hoping the higher voltage architecture would require less current for the same charging speed and therefore less throttling from thermal limitations. I wasn’t expecting a “dramatic” increase, but I also was expecting more than a slight increase in charging speed almost entirely coming from the 0-5% range.
99% of us are still limited by our cars. Just being able to hold v3 speeds at 250kw deeper into the battery would be a huge improvement. Like the new Taycan that does 315kw to 60% and 250kw to 80%. If a 3 could hold 250kw all the way to 80% you’d have a 0-80% charge in 15 minutes vs about 35m today
As an owner of both a Hyundai and Porsche -- yay 800v! My Porsche will go from a 68m charge 10-80% to an 18m charge. Superchargers are pretty useless for me right now.
Sounds like you didn't opt for the 150kW on-board booster option on your Taycan.
I did not
So not much difference from a Model 3. CT consumes more energy so faster = same time
Model X Is a better road tripper because of the efficiency and charging curve is flat till like 40% and you don’t need a fancy 500kw charger
800v architecture and charging infrastructure SHOULD yield twice as fast charging as 400v.
The voltage across each cell is the same. That said: It chargers faster than any other Tesla, but the limitation on 500V is the plug, not the battery. It’s not the peak charge rate that’s important, but the area under the curve.
Still too slow
Yeah why doesnt tesla do this? I would love 0 to 80 in 15 minutes.
Hit that peak rate for all of 1 minute?
The high peak rate is extremely misleading because it drops down so rapidly. Unfortunately it still has a terrible charge curve. If you want to see a good charging curve, have a look at this video. The Zeekr, MG and Mercedes can hold 200 kW for much longer than Tesla. https://youtu.be/Cy46Ag0djjk?si=87mvlKBX_J0jjcDr
Will buy my CT as soon as it has 450 mile range and can charge on V4 800V native platform full speed. I need to tow in winter mountains.
rip battery health
The 3 and the Taycan are in totally different price categories. It would be nice to see an S with those specs, but Tesla hasn’t prioritized S/X R&D for a long time. Even the plaid is just the motors from the semi with a different gearing.
Will probably matter more once they release a longer range CT or something similar where the pack can take 500kwh for a meaningful amount of time
Yawn
That's not how it works
That's exactly how it works.
The cybertruck is already running into the cell charging limits. Changing the pedestal output voltage to 800V would have almost no impact on charge speed.
Then why is it slower on 400v?
no
It could be because of charger or plug limitations but the battery thermal limitations are not mitigated by higher charging voltage.
This is not because 800V battery is a faster charging battery. It is slow on 400V because of the way it was designed. Only improvements 800V brigs is power delivery from battery to motor -> skinnier cables and power delivery from charger to car -> skinnier and cooler cables/plug.
Find me a 400v car that does 10-80% in 18 minutes with independent testing. I acknowledge that it's technically possible for a 400v car to do it. But in reality every car with a good charge curve is an 800v architecture.
Yeah I went from a model 3 to a sierra ev, and apart from being able to pull more from the 800v chargers now, the first thing I noticed was how much power it continues to pull. For how much larger the battery is, pulling 200kW at 800v is like pulling ~37kW at 400v on my old model 3 as far as cell amperage goes. I’m hoping to keep seeing improving charge curves and chargers that can take advantage of them
It's not really except at very low SoC
So why is this a big deal?
It'll be helpful in the future for cars with larger packs or cells that can charge at a higher c rate. Currently it should be an improvement for cars that have a low amp limit but can charge at the higher voltage.
The post says the truck hit 483kW charging rate at a V4 charger. Apparently that's a big deal? What did it charge at on 400v chargers? The limiting factor is the amps they can push through the cable without something bursting into flames. Watts are amps X volts. If you double the volts you double the watts.
That only matters if the vehicle is running into the amp limit. Even the cybertruck can only charge at the max V3.5 amp limit for a few minutes at very low SoC.
Re the “totally different price categories” being a reason: https://www.reddit.com/r/teslamotors/s/qrd3mwQSrd
Yeah! Love what BYD is doing! Any idea why this tech is just in China? I'd think packs with that price/performance would be a hot commodity in higher margin export cars out to Europe at least.
Total guess, but perhaps because it’s not yet proven whether the packs will hold up longer term? Also, maybe BYD want to reserve their cutting edge tech for their own cars.
Probably greatly increases battery degradation.
Charging fast is great, but vehicles built profitably is what I care about. All these vehicles losing companies 20-80K a copy, they probably won't be produced for much longer. Cybertruck is made profitably, just like all of Tesla's "slow" charging vehicles. That's what I want, a company and model that will be around in a few years.
Meh. That truck has put the entire company into Limbo.
