ok i work in a kind of tangential industry and can kind of answer this probably
in general the higher the voltage the smaller the current, which you're generally happy about because your 1) electrical losses and 2) cable/wire diameter are both proportional to current
the tradeoffs being 1) it gets harder and more important to isolate the circuit (e.g. your wire insulation that prevents the 12V bus from shorting out to the vehicle chassis now needs to be thicker) and 2) all the stuff people make for cars (i dunno, windshield wiper motors, radiator fans, whatever) is currently for 12V
in general this move probably makes sense, provided they're able to figure out their supply chains, and if tesla can position themselves as being like the first company to figure out a bunch of these 48V components at scale that's probably going to be really good for them. they did a kind of similar thing with the charging infrastructure if i understand currently, like now the tesla charging cable is the de facto north american standard
I'm no expert, but even with ordinary 12V wiring, the insulation is generally rated for up to 600V, just because it's not really practical to make it any thinner...
The charging cable isnt de-facto the standard. It is the standard now. All new vehicles from the big 3 and many foreign manufacturers will utilize NACS.
Pretty sure we're still waiting on Stellantis?
Them and VW.
I was reading VW might be more complicated due to the emissions scandal and the requirements of rules for EA, but not a blocker, just more to work out.
For sure. Might have jumped the gun on stellantis, but they will fall in line with Ford and GM.
Regardless, NACS is here to stay and will be the standard moving forward. Tesla gets a fuck ton wrong, but their charging system and charging logistics is light years ahead of the competition.
