Consider the cable sizes. For a given power, the higher voltage is
smaller copper and thus lower weight.

"Safe" is considered to be anything less than 52V. There was once
talk about the automotive industry moving to a 48V battery. The
reason for 48V was that it was just below the "safe" limit. Of course
it never happened because it would have caused more problems than it
solved.



When was that talk? No doubt, there is always something in the air but
I never read or heard of that back when I was in the automotive business.

I'm sure it was intended to help make vehicles lighter in weight.



Coming soon, evidently


Not every electrical component will switch to 48-volt. Lights, radios,
electric windows and door locks, for example, would stay 12-volt. And
Delphi?s vision is that vehicles with 48-volt systems would also have a
strong regenerative braking system to capture much of the energy lost
when a vehicle slows down.

And when you can buy a car that says "Delphi
Motors" on the front then the industry will give
a crap what bull**** "Delphi" is trying to sell.

Bolt runs on 350v, Volt runs on 360, Tesla runs
on 375. All have 12v subsystems to support
various accessories. The notion that 48v is of
some great advantage in building hybrids and
electrics has little contact with reality.
