Comment on BYD announces charging tech that’s twice as fast as Tesla’s
humanspiral@lemmy.ca 3 weeks agojust searched for 1000a bms’s and they don’t seem ridiculously large. unlimited length cable needs under 1cm diameter copper as code. Not crazy either. And a calculator says that 10 feet would only have 4% voltage drop at 13awg (house wire size).

I’m using 8AWG from the solar for 1,200W. While it may be overkill, well, one doesn’t want to start a fire in a van. That runs about 80A, so I’d likely be fine smaller, but 1,000 amps being “just” a centimetre is something of an absurd claim. I suppose compared to gas pumps, it’s tiny!

I agree that the calculator seems to be dangerous result. Code says that 9mm 2/0 AWG copper is needed. Insulation not counted.
