  • 800V architecture

    From JAB@21:1/5 to All on Wed Oct 18 21:06:30 2023
    Cybertruck

    At the same time, the vehicle's electrical architecture is reportedly
    now being redesigned to accomodate an 800-volt standard, up from the
    400V its existing Tesla lineup. A lot of luxury, performance and heavy
    duty EV models -- from the Audi e-Tron to the GMC Hummer EV -- utilize
    the 800V architecture, it's what enables EVs with large battery
    capacities to charge at a higher rate (thereby reducing charging time)
    without reducing the vehicle's wiring harness to slag.

    Gotta wonder, though. Plenty of commodity wiring is
    rated to 600V, so this would be pushing it.

    Hmmmmm... then again, that's 600VAC, which gets to a peak RMS
    of.. 942 (iirc my 5th grade E&M), so if Tesla can get
    the various regulatlry folk to put an Asterisk on their
    approval charts to recognize this difference...

    How absurd and wasteful. There's no need for such large heavy electric vehicles, such as a Hummer or other unnecessarily large SUV's. What a
    waste of resources and batteries. Small electric vehicles are far more practical and efficient.
