"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.

Jeez even more reason to do work on you car yourself, especially
electrical. I recall electrical being so touchy in the early 80's that
factory standards called to replace a broken wire, like to a signal
lamp, with the complete socket and wires that came with the socket.
shortening or lengthening the existing broken wire would set off error
codes. I'm clueless how one determined if the new pigtail would shorten
or lengthen the run being observed by the ECM.
