Master Plan Part 3: Cybertruck Stated To Carry a 100kWh High Nickel Battery Pack, ex. Model X / S

[Ogre]

This is pure speculation, of course, but I suspect that the Cybertruck will have at least a 140 kWh battery pack for the regular range and a 200 kWh battery pack for the long range.

Yeah, I think if the basic truck has 140 kWh we’ll have better than 350 miles range.

One thing people sort of blurred. Possible the shorter range and long range both are double stacked. The shorter range might have 60-70 kWh/ layer while the LR has 100 kWh per layer.

What is this from? 100kWh will not be the max cybertruck pack, but it could be the base.

100 kWh might be the base for 300 miles and no towing. I envision 170 kWh for 500 miles and 250 while towing.

...Generally cars use cabin fans because it's more aerodynamic to not have flow-through vents on the skin.

Like, I haven't had a car with a flow-through vent since the 80s. And when was the last time an American car had one? The 60s?

A NACA inlet would take care of that very nicely. I built 2 Composite Aircraft that had 1 each for engine and pilot air no great increase in drag.

They still increase drag. 'No great' well, you have eight additional ones there. That's alot of extra space that doesn't need to be.

That is why having only one maybe under the bumper would be a great way to allow air into the cabin with not electrical drain. The ICE vehicle is so loud driving an ev is so much quieter. You hear road noise and air noise even from a window in a different way. I really like the idea of not using range when you don't have too, and keeping is quiet. Too many years in loud industries has reduced my hearing but the left ear always gets more noise due to the open driver window. Just me I guess.

Tesla is realy stingy with batteries, so I doubt they shoot for a 350 mile range. More likely they will choose to just clear 300 miles. So 310,320.

People probably don't perceive added value in small increments. Even the EPA range isn't real, of course.

As I said elsewhere I doubt Tesla builds any longest range pack vehicle in the beginning. Assuming 4680 production has determined CT release date they are unlikely to be interested in putting 200kWh in one vehicle.

This my crazy prediction from another thread is this... the CT will have an efficiency of 400 wh/mi.

In this scenario a single motor will have 100 kw pack just like in the master plan 3 image.

This will net about 250 mi range. Like they originally planned.

Dual motor will have a 150 kw pack. The main 100kw pack is standard throughout the lineup and is where driver and passenger seats are bolted to just like in the model Y in Texas. My prediction is that Tesla will have smaller 50 kw pack that can be added under the main pack to add range where needed. So instead of making 3 different packs...they just need to make two battery modules one 100kw and one 50kw. This will net about 325-350 miles of range. Less efficient maybe around 425 wh/mi

Tri / Quad will have 200kw pack. One 100kw pack and two 50 kw packs under main pack. This will net their claimed up to 500 miles. With their motor decouplers tech to run more efficiently like in semi.

If they do go this route. It would be very easy to spec out a dual motor at 150kw and have the option for more range by adding another 50kw battery module.

But i also think just building 3 packs at 100, 150, 200 kw packs could also work.

Pretty sure this slide is not describing what CT will use.

the chart is within a section describing how transition to green will require, amongst other things, conversion to BEVs - and providing estimates of what that future may look like or require.

This slide is then attempting to make an estimation of the TWh of batteries that would be needed for complete BEV conversion globally. To arrive at that TWh estimate, it assumes that larger vehicles will need more energy-dense batteries, and will on average need about a 100kWh pack of those high density batteries.

This chart simply gives a “Tesla equivalent” example of the sizes of vehicles likely to need various energy-density packs, and on average what those pack sizes would be, in order to come up with a loosely accurate estimation of global TWhs needed.

It does not say that the CyberTruck itself will use a Nickle battery, or have a 100kWh pack, when releases. Maybe it will or won’t, but this chart isn’t taking a position on that

Here’s the operative description of the chart (and it’s FN):

“Vehicles

Today there are 1.4B vehicles globally and annual passenger vehicle production of ~85M vehicles, according to OICA. Based on pack size assumptions, the vehicle fleet will require 112 TWh of batteriesaa. Autonomy has potential to reduce the global fleet, and annual production required, through improved vehicle utilization.

Standard-range vehicles can utilize the lower energy density chemistries (LFP), whereas long-range vehicles require higher energy density chemistries (high nickel). Cathode assignment to vehicle segment is listed in the table below. High Nickel refers to low to zero cobalt Nickel Manganese cathodes currently in production, under development at Tesla, Tesla’s suppliers and in research groups.

[FN:]
To approximate the battery storage required to displace 100% of road vehicles, the global fleet size, pack size (kWh)/ Global passenger fleet size and annual production (~85M vehicles/year) is based on data from OICA. The number of vehicles by segment is estimated based on S&P Global sales data. For buses and trucks, the US-to-global fleet scalar of ~5x is used as global data was unavailable.”

You beat me to saying this, and you did it better than I would have It is amazing how many folks, including some media journalists, who see "Cybertruck" and "100kw" and jump to the wrong conclusion.
