OTOH, it also says “+50kWH” to fill the remaining 29%, which makes it a 172kWH pack!

The +50kWh is how much he’s added to the pack since the beginning of the charge session.

+50kWh is how much has been added already during this charge, to get it up to 71%

without knowing what % it started charging at, we'll not get too far

Dammit. Beat me by a few seconds. ??

Sweet new profile pic btw ???

So if he started at 0%, it’s at least a 70kWh pack? Hmmph

hey, if you ever wanna come play a game of "I'll show you mine if you show me yours," you're more than welcome!

but if he started at 70%....

With the info seen on the screen, there’s no way to know what the state of charge was when he started.

Any confirmation/insight on my reverse math? 71% current charge - 65% destination charge = 6% of usage to go the trip distance of 16mi. Now I l know it can introduce a bit of variance when extrapolating from small numbers but I’m getting 267mi of total range . . . ??

OMG the audio of that video had me struggling for the volume control on the first watch, couldn't even notice the details

Well 6% to go 16 miles suggests total range ~270 miles. It looks like it’s interstate driving so usage may be higher.

Based on prior speculation of 0.4kWh per mile that would put the pack size just over 100kWh. The charge rate of 77kWh @ 71% also supports pack size around 100kWh as the MX charges at about 84kW at 71% and has a 100kWh pack. If this pack was substantially larger, you would expect a higher charge rate at a given SOC based on C rating be held roughly constant.

Didn't the master plan tell us pack size?

Any battery experts ( @JBee ) want to break these down?

Only just saw this but I think the numbers are out a bit.

From memory the KWh shown is the amount already charged though.

Then if you look at the charge rate at 77kW, the 55 minute time remaining makes no sense, the battery would be huge if it would still take that long, at that SoC and that charge rate. Either it's wrong or it tapers the charge very fast to get it out to that remaining charge time.

But @KScheidt was on the right track:

If I am reading that right it shows 71% on the dash with a trip remaining of 16mi and an ending charge of 65%. So . . . 267mi of range?

That's 6% of battery for 16miles, or a total of 267miles per pack, giving around 3miles per 1% of SoC.

On a 115kWh useable SoC (125kWh) pack that is around 443Wh/mile, which is within the ballpark of expectations, although a bit higher, probably due to the driver "testing" the CT performance.

Master Plan 3 did not provide pack size, they simply stated the battery size needed for that category of vehicle at a macro level to hit the goal of a zero-emission future. That was not Cybertruck specific, though some people though it was because of the cybertruck outline.

That Master Plan was talking about global industry and showing math on how to get there, it was not implying specific battery sizes for specific Tesla vehicles.

If this pack was substantially larger, you would expect a higher charge rate at a given SOC based on C rating be held roughly constant.

If we look at it from the erspective of the possible charge rate at that SoC on a 115/125kWh, we need to factor in the extra battery capacity at the same C rate to get the right numbers as well. (I've used the 21700 C Rate as reference)

So you should be getting a charge rate of 98kW at 70%, 70kW at 80% and 42kW at 90%.

But 70% to 95% should only take 28 minutes to add 44kWh not 55 minutes like it says on the screen.

Yeah, I don't post much. It was a joke, just as any other assumption on here. We all know what assumptions do.
