Aren't most all vehicle electrical items switched electronically these days? Everything seems to go through some computer. > Main pack dies - you can't turn on the emergency flashers. The same thing happens if your current 12v house battery goes flat. > 300VDC switches are MUCH more expensive and complex. Is it more expensive to design semiconductors to switch 10 amps at 12 volts, or 0.4 amps at 300 volts? That's not a rhetorical question: I don't know. > Accessories need to work over a large variation of voltage. (280-330 in > my truck). You could regulate the accessory bus.That would provide the side benefit of allowing a range of nominal voltages for the traction battery while standardizing accessories at, say, 100 volts. But if you're going to do that, I guess you might as well just "regulate" it down to the now-standard 12v.
