No sure about vans, but aren't lots of cars moving to 48V?

- IshKebab 2y agoYeah because higher voltage reduces the cost of wiring, and 48V is still under the 50V legal limit for "low voltage". Not sure what your point is though.
- fragmede 2y agoif the are power electronics chip they use is rated to handle 12 VDC to 48 VDC, which 30 VDC happens to be in-between, then they could just use that chip and you could give it 12V or 48V, whichever you had handy. If all cars are moving to 48V, that makes that more likely.
- yencabulator 2y agoThat's a very wide range and to build a gadget to take that range would cost more, and thus it's not done. Most "12 V" gadgets only accept the rough range of what a 12 V battery might give them, which is usually only up to 15.4 V while charging.
- fragmede 2y agoUSB-C 3.1 PD does 240 watts by raising the voltage to 48V, so the chips to accept that already exist, even if they're expensive right now.
- cma 2y ago> Not sure what your point is though. If it runs off 30V all you need is a cheap resistor to run it (with 40% loss), or I believe boost convertors are less efficient than buck convertors so it is a win there.
- yencabulator 2y agoSome manufacturer RVs and DIY builds are 48VDC now with stepdown converters for the legacy stuff that expects 12V. The problem with that is that practically every RV gadget on the market assumes 12V. It's a chicken-and-egg problem.
