Tesla Cybertruck Charging Curve Confirms Poor Charging Performance

[jandrese]

I had wondered what neat trick Tesla was going to use to cool those chonker 4680 cells. There is a reason you can't buy rechargeable C or D size batteries even though there are hundreds of options for AA and AAA batteries. Electrolyte is a pretty crappy thermal conductor.

You can buy those though. They may be harder to find in physical retailers, but there are plenty of options out there.

My 4x4 RadioShack remote control car from 1989 would beg to differ.

This thing looks like the most inefficient vehicle of all time. You can see with your eyes that it's poorly engineered. Why did anyone believe any of the positive claims made about it?

[Galanwe]

I mean, every serious review out there places the cybertruck as a solid choice for electric truck, on par and reasonably priced against alternatives. Surely not as hyped as originally planned, but still a solid choice.

What amazing eyes do you have that spot "obvious poor engineering"...?

Tesla owners have a lot of reasons/excuses, ranging from "Teslas only get 75% of their claimed range in optimum conditions anyway", to cold weather, fast driving, HVAC use, open tonneau cover, inefficient all-terrain tires, driver ineptitude, preheating for Supercharger usage, non-availability of V4 Superchargers, and on and on.

The whiplash is severe as people are still quoting the imaginary 500+ mile range from 2019.

689Wh/mi is 428Wh/km... that is utterly insane energy use. My Zoe (small car) needs 150Wh/km in winter and I wouldn't get a car above 200 or 250.

They spent all their time trying to make the stainless body panels actually align, and a shoddy battery got through.

It's really interesting how, every time a negative point about Tesla appears on this forum, there's an instant chorus of defenders who jump in and punt it how 1. biased 2. incorrect and 3. ignorant, the original post is.

It's almost like Tesla has hired a top tier PR agency to manage negative social media content and protect its reputation.

There's nothing illegal about that of course. It's just really impressive.

As my grandma said, better late than exploding in a ball of fire.

This is a sample of one. Not many of these things out there.

It will get a software update and will charge faster in no time.

> It will get a software update and will charge faster in no time.

This is certainly possible, especially if the reason for the slow charge is that the cells were rushed into production so fast that Tesla didn't have time to characterize them, and don't know what charge conditions will damage them. On the other hand, the 4680s have been in production, in one form or another, for quite a while now, including in Model Ys which show the same slow charge performance, so it's also certainly possible that the cell quality is such that they can't be fast charged without damaging them, regardless of software tweaks.

I feel like at this point any v1 Tesla should come with a warning. Some people don’t mind being beta testers, others do.

[schneems]

Do you have any info to back up that claim or is it a guess?

[chris222]

The current Superchargers are not even 800v yet.

For 2024 you could consider to to form a habit of pointing to sources that support your statements (or mark them as things you want to believe) — this is better for everybody involved.

Or, you know, just don't submit the post after writing it unless it really adds something to the discussion.
