An EV fast charger can do 1000V, so with a bit of logic that sounds doable.

  EV chargers take a different approach. There is no power on the connector while you're plugging it in. It then locks in place before the contactor closes and power is delivered. Unplugging is the same, power is removed before the plug is unlocked for release.

    Do the EV chargers not have an alternative disconnect sequence for when the two sides are forcibly mechanically separated? Either by accident, malicious intent, or mechanical failure of some component.

      Yes. See UL 2594.[1] There's a lot of monitoring on those things, plus regular circuit breakers and GFCIs. [1] https://www.intertek.com/batteries/automotive-battery-ev-testing/evse/ul-2594/ https://www.intertek.com/batteries/automotive-battery-ev-tes...

    This is effectively how hot swapping is done for may modern systems. It seems counter intuitive to call it hot plugging, but it’s what you’ll find if you look up “hot swap controller”.
