When the green ring has been dislodged as shown
in the post above, is it difficult to re-seat the ring
properly using a medium or small flat-blade screwdriver?
Or, if one needs to use that J1772 plug to charge, is
the only in-the-field choice to remove the ring, perhaps
with a screwdriver or a pair of long-nose needle-nose pliers?
In any case, whenever plugging something, especially
some "publicly-used" object that might be "infected",
into anything that you value...
one would be wise to use great caution, and perhaps
even some isolation technique, or at least a careful
examination of the object to be inserted?
In these "early days" of public charging, where these devices
are still evolving, and more often subject to misuse, or even
vandalism, might a cautious owner want a short, rigid socket-
to-plug device that would plug into the EV's J1772 socket,
and provide a "disposable" (or easily replaceable) J1772 socket
to accept the "public" J1772 plugs?
The adapter might even have some components to keep
poorly designed, defective, worn, or out-of-spec EVSEs
from damaging an expensive EV or Charger that fails
to protect itself sufficiently well from "unexpected" input.
Would you buy such a "protector" device for $100?
Yes, right now, it would cost more than that.
