@@MunroLive the reason they have so many screws holding down the board is because if you use snap fittings the board will flex. There are some connectors between boards. If you use the snap fasteners the connectors will move slightly with vibration and the boards will flex. That will cause the connectors to fail and the boards to fail. The screws hold the board to the aluminium frame which stops the board from flexing. They did the right thing by using so many screws.

[@privateerburrows]

As an electronics engineer myself (retired), I was delighted with this show. Thank you! Designing without fuses and without relays is what I always tried to do, when I could get away with it. Most of the time I did not have the liberty to do things right, though. Heck, once I cheated: Our client was very biased against micro-controllers because of their sensitivity to EMI noise, and tendency to reset back to power-up mode when struck by noise; so he wanted a controller made of logic chips, transistors and relays only. I had developed ways (in hardware and in software) to make micro-controllers impervious to EMI noise, but I could not convince the client. But so, I designed his prototype control around a Motorola micro-controller, but I added a relay to the board *not connected to anything;* just to make relay noise and make the client believe I was using relays. 😏 After he tested the controller for a month and approved it, I told him it used a micro-controller, and he took it well, had a big laugh. One nice thing about that project was that I had to make the functioning of the controller seem as simple as a relay control would be. Designing the software to emulate the simplicity of a system using only relays and transistors was a great exercise in itself, it caused the code itself to become simpler and better organized than if it had been implemented as a standard state machine. That effort influenced my firmware development for the rest of my career. And I used to advice firmware programmers to try to design their firmware to behave in such a natural way that a user could not tell the machine was being controlled by software. It is a great goal to have, for some reason I cannot fully explain.

[@ohger1]

On low voltage designs, I would sometimes use poly resettable fuses.

[@privateerburrows]

@@ohger1 I've used them too. What's important is to be clear about what the fuse is there for. If the purpose is to limit current in case of an external short-circuit or other user error, it makes sense to use a resettable fuse. If the purpose is, on the other hand, to prevent the circuit board from heating up and starting a fire in the case of an internal short or failed device, then a resettable fuse makes no sense, and it does not even make sense to use a fuse that can be replaced by the user; might as well go for a soldered-in fuse.

Thanks!

[@Aser6000]

Engineering is always a balancing act. If you integrate all the controllers, it means you need a lot more wiring and connectors, because you need wires going to every switch and actuator. If you add a separate door module and a seat module etc, then you only need 4 wires (or less if you put power and data on the same wires) going to each area of the car.

[@maraudermanmarauderman7161]

Yup, decentralized modules mean less wiring, cheaper to repair and gives you to more easily and cost effectively make changes to one thing w/o having to change everything.

[@stephanweinberger]

And ideally you also use a common bus for communication between those modules (e.g. some type of realtime Ethernet). Some less critical modules could even be daisy-chained to get rid of even more cable (no option for critical systems, as a failure in one module might make the rest of the chain inaccessible), while more critical system even could have redundant/meshed connections. E.g. I find it interesting that VW is using Ethernet for the cameras - to me that's a hint that they are preparing to use more and more Ethernet in general (plus it might even reduce cost, as IP-Cameras are cheap mass-produced parts).

[@maraudermanmarauderman7161]

@@stephanweinberger Don't know about the Mach-E but older Fords typically have 2 CAN buses. High Speed for those mission critical items that need that speed like power train, ABS/stability and SRS. Medium Speed for non mission critical items where the speed is not as essential like door and seat modules . The other reason to have a separate non-essential bus is to prevent failure of one of those items taking down the mission critical bus. There is a certain era of Chyrsler mini vans where the not uncommon instrument cluster failure shorts out the main bus causing no communication and no start. Unplug the instrument cluster and the car starts and the scan tool can communicate again.

[@xavierStark84]

I believe dear Munro and Sandy team, you probably have seen some TeslaBjorn's videos when you can see how simple is to connect an interface to an ODB connector and use an App to have all the right numbers from the vehicle, including the battery ones, temps, motors, etc. Just in case you didn't saw that its easy to find it here on YT. Easy to use, easy to find (now) and easy to compare the info from the vehicles. That's less than 2 years from the first Model 3 arriving to Europe (he's being using the connector from some months). Maybe this explains who easy is to do better software forthe vehicle, as an example. Thanks again for the lessons learn on videos like this one.

unfortunately the elimination of parts is making right to repair even more difficultt, just look at what apple is going, and tesla has been copying apple for years now. i dont see the problem with having more electronic parts that arent moving, its not like moving ICE parts

[@abraxastulammo9940]

Something to think about: the quick (and dirty?) development approach of VW probably saved them a year compared to regular development cycles which means a billion (ballpark figure) of avoided CO2 fines and a time to market and BEV production capability that is only maybe a year (and a half) behind Tesla.

Very interesting. About a year and a half ago I really wanted to by an electric car. Being both retired and someone who uses a wheelchair (but can walk with crutches), I wanted a car that would allow me to position my wheelchair behind the driver's seat. A Tesla would have worked EXCEPT they could not remove the captain style seat from behind the driver's chair. I ended up purchasing a new VW Atlas as they could remove the seat without any problems. Tesla said that it would mess up the signals to the control module if that seat was removed. Note, my first job as a 16YO kid in 1962 was as an electric golf cart mechanic.

The old obsession with every gram of weight reduction applies well to racing but saving 10 kilos in fasteners, wires or slimming down plastics often results in cracked, loose or broken parts over a 15 year cycle of vibration and impacts and weather . When batteries weigh so much of the total vehicle mass, going too far into weight and cost reduction everywhere else eventually produces failures of reliability. Trying to remove and service a heat cycled piece of brittle plastic instead of a metal screw or bracket has caused many a tech to curse the engineer and bean counter who ordered it.
