2021 Volkswagen ID.4: Battery Teardown

[Homer J Simpson]

Interesting tear down and info on the design of VW ID4 battery.

Maybe not so much as a tear down but a design and construction analysis.

Added motor / gearbox tear down.

Pfff... more ranting against using screws. And his comment that car electronics aren't being repaired at the component level is simply not true. Even in a small country like the NL there are a few companies that specialise in repairing electronic car modules like ECUs.

edit: to me the inverter from VW looks like it has been designed for easy module / component level repairs. They could have filled the entire thing with silicon snot for example.

Every time I watch Sandy's videos,  I do wonder why people pay this guy for consulting.  He may understand the mechanical engineering aspects quite well but he's clueless about the electronics or systems integrations parts.  Making a battery casing from thermoplastics?  Come on!  Have he not seen the Tesla fire saga?

IMHO this guy is very opinionated and just clueless in general.
The battery pack is made this way, modular so they can configure the car for different battery sizes. It might be even possible to replace the pack per module. The ID3 uses the same modules. There it's more efficient to produce these modules, assemble them somewhere else, not directly into the car, and just slap it together on the production line.
He proposes to replace the aluminioum extrusion with polimer. Probably some glass filled plastic. Very hard to recycle, Aluminium (written the correct way) is very easy to recycle.
His video is basically how to turn a modular, well engineered battery pack into an unrepairable mess (just like a tesla).
I also loved, how he said in the begining that this is worse than the model 3 because it weights more. Weight/capacity is almost the same
