My point is that Tesla won't be making 600 a week anytime soon, so they have cells to spare and 4680 production will ramp faster than what Cybertruck production will require In fact, again from the OP video, they will have trouble finding where to stuff the amount of 4680s they will be making...

Hope this will stop the : "They can't ship the 500 mile version because they don't have enough 4680 cell supply" They are way ahead of what Cybertruck will consume today, at a 5 GWh/year run rate, they could build 600 units per week of the 500 mile version TODAY, and the 4680s with more lines...

I'm betting way lower than that for 500 miles Rivian recently released their Max Pack and in house dual motor drivetrain, in which they switched cells and have a total of 149 kWh and 410 miles of range. 363 Wh/mi or 2.75 mi/kWh My previous estimation for Cybertruck based of upscaling a Model...

Biggest noteworthy thing for me that is somewhat young is inverter whine, on Rivian I can hear it on most if not all videos, dead silent here

Yes it is, it's gravimetric energy density, there is also Wh/l, volumetric energy density Both terms are used in the battery industry for a long time

Here, the three highlighted ones means directly energy density improvement at a cell level, so 40% energy density improvement on the 6 years after battery day, but we all know how Tesla works, turns the impossible into late, so they will get there, likely taking more than 6 years This means...

You guys discussing that it costs too much are forgetting IRA manufacturing credits There is plenty of space for a double stacked nearly 200 kWh pack, even more now that the 4680s V2 are 95 Wh per cell, but let's go with 180 kWh for 500 miles since that my prediction and compare to other Tesla...

If you consider the 285/65/R20 tire, and that the bottom is more or less aligned with the center of the wheel, this comes around at 17" ground clearance

Thanks man Yeah, because it's more effective, the second paper goes into detail on the why, and also recommend this video that is a summary of the paper But the TLDR is, while cooling the bottom seems more effective because the thermal path is shorter, the performance is worse due to the...

I'm the author of some of the graphs John used in his video I recommend reading these two papers, the amount of ohmic losses heat generated inside the cells due to the tabless electrode is greatly reduced to almost nothing Also as shown there, the most likely explanation with all the data we...

Yes, but you can't say a cell has less energy because you only want to talk about nominal energy Current 4680s have 86.5 Wh of capacity, period

Again, Troy confusing things One is usable energy, another is gross capacity, there is a bottom buffer When we talk about pack size it should be the gross capacity

As always, Troy with wrong info Current 4680s are 86.5 Wh, making the 10% increase be 95 Wh I'm on the team double stack of 4680s for sure, copying my latest speculation from somewhere else, and this is was before the earnings call, so numbers are better than this

Seeing all the wrong units here makes my head hurt kWh - Energy, pack size kW - Power

Yes

That isn't reinforcement, it's the sprue and runner channels from the casting process, it will be all trimmed off

Wish they built an off road test track nearby so we could see how it goes

Not a silly question, but a single layer pack would need a 4680 to store around 200 Wh, or more than double than now Specific energy for that is around 560 Wh/kg, so no, 500 miles won't happen in a single layer anytime soon, maybe when the refresh of the refresh of the refresh Cybertruck...

Yes, impossible to have 500 miles of range on a Single layer with current battery tech And there is space for it

I went down that rabbit hole a few days ago The TLDR is that 500 miles Cybertruck is definitely doable with current 4680s, the pack will have to be double stacked But the important point is, the pack would always have been double stacks of cells for it to happen, 4680s would need to have...
