why not? it works, it has industry wide support and a huge range of products, and it's safe without excess need for shielding and isolation. it's closer to the actual operating range of most equipment, so it produces , in most cases, less intrinsic need for shifting voltages around, and the wiring that would get substantially smaller is already near size limits for dealing with vibration and harshness.
aside from trying to get closer to the operating voltages of whatever arbitrary energy pack we're specifically talking about , what's the point? if anything it would just wreck any hopes of cross-industry compatibility for a long time for very little manufacturing efficiency gains or energy savings.
tl;dr: the vast majority of car 12v is lights and logic, and they're closer to 12v than 200v in the vast majority of cases.
- Podgajski 3y agoI agree. Probably 90% of the power I consume is from a 100 watt solar panel and a 12v solar battery as I currently live out of a minivan.
- callalex 3y agoI guess that really depends on how you define “consume”. For example do you do your laundry by hand or do you use a machine that lives outside your van?
- theluketaylor 3y agoYou're massively underestimating just how much wiring is in a modern car. The car industry has been trying to move to 48V for decades to save money on wiring and Tesla just succeeded with Cybertruck. High consumption devices like electric power steering, electric A/C, and active anti-roll bars all require huge amperage to run at 12V and are only becoming more common on cars. Car makers project big savings in moving to 48V and it's going to become a lot more common.
