Cybertruck Electrical and Network Architecture - deep dive review

[Mini2nut]

For all of my fellow nerds.

I found a great YT video where the author goes into a deep drive regarding the CT electrical architecture. For example, Tesla vehicles don’t use traditional automotive fuses and he explains what Tesla uses instead (power MOSFET chips).

It’s a deep dive that I found very fascinating. The video shows how advanced the Cybertruck circuit boards and electrical architecture is. Tesla employs some top notch electrical engineers.

FYI, Aside MOSFET fuse in the Model 3 ... 7+ year ago.

Below from: Questions about lack of fuses on Model 3

They use MOSFET "virtual fusing". So one of the body controllers monitors the power being consumed by the phone charger, and when it exceeds the limit for that particular circuit, it cuts power do it. Sort of like a virtual circuit breaker, but without any moving parts. Then when the fault is cleared (you unplug the faulty charger), the system restores power to the circuit. This also allows the car to tell you "Overload in Cigarette lighter port, power interrupted", this way you know something is wrong and can take action. This was done for fault tolerance, but it makes the car safer and more reliable.

@Phil Truby and @Mini2nut this is brilliant! Great way to learn about the power and control architecture of the CT. Thank you for contributing this to the group!

I watched both Munro & Caresoft dissemble on Cybertruck, reserved when unveiled live back then and saw it real-everything about Cybertruck is so amazing except the size-patiently waiting for a midsize Cybertruck.

I don‘t see a mid size Cybertruck in the works considering how Cybertruck sales have not lived up to expectations.

It’s not as easy as just shrinking the dimensions 20-25%. The truck would need to be completely redesigned, engineered, all new tooling, etc.

Even if they did, the cost wouldn't scale with size. It's pretty clear mid $70k is the low end of the EV truck market for now, and "mid size" truck wont change that. People holding out for a 500mile EV Maverick for $45k need to come to terms with the reality that we wont see something like that anytime soon.

Agreed. Especially if one is expecting a damage resistant cold-rolled stainless steel exoskeleton. Making it slightly smaller simply isn't going to save that much money because the cost to make a vehicle has more to do with the number of fabrication and assembly steps than the exact size of each part.

Making the Cybertruck 20% smaller would only save about $3-5k (at the most). As much as I would like to see one, even though I'm sticking with the full size product, I don't think a smaller Cybertruck in the next 5 years is in the cards. A truck is defined by it's capacity, making it smaller reduces it's functionality more than it reduces costs. Sure, some would like that, but most people (well over half) are going to prefer the larger version. With the steer-by-wire and rear wheel steering it drives like a much smaller truck already.
