That's handled by the Proximity connection, when the car sees this is
connected it will not allow drive. (One of the 2 small pins on the
connector)

It's simple, you just have a mechanical lock like Tesla's original CCS to
NACS adapter, you connect the DCFC to the adapter, and then when the
adapter is connected to the car, a spring loaded pin or other device is
pressed in by the body of the car's inlet that locks the DCFC whip to the
adapter, t

Would it work to have a locking connector combined with a tether activated

I have personally tested a number of CCS DCFCs, and NONE of them
de-energize fast enough to avoid arcing when Pilot and/or Proximity is
de-asserted. It's a tall ask to have a DCFC putting out 500 amps and 800

a latch.

I should note that the connector is designed so that the pilot wire
(communication wire) is the very first to disconnect. If the regulation
is followed correctly, this should automatically de-energize the entire
circuit, before the connector comes apart completely.
> Locking connector rant
I have discussed this here before, but neither the Lectron or the A2Z have
a proper mechanical interlock, meaning you can literally rip out the NACS
cable while HV is still present, which could result in an arc flashover
between the terminals with full pack voltage. This could generate over a

Hi all,
Marco Gaxiola sent me a link to a report done by the ChargeX Consortium
"Recommended ACTIONS TO IMPROVE ADAPTER SAFETY" that he and several others
have written (Marco said he was the main participant).
It discusses the safety issues of the DCFS CCS/NACS adapters and has
