However, a cable at a charging station will have a connector at the free
end.
The cable does not end with bare wires.

The question then is how to designate that connector.  Is it a plug or a
socket?
The answer is not as clear as many think.  See
https://en.wikipedia.org/wiki/Electrical_connector#Plug_and_socket_connectors

Despite what the Wikipedia article says, the terminology isn't as clear-cut
as
it implies and different industries have different, conflicting naming
conventions.  Within a single industry different naming conventions may be
applied to different styles of connectors.

Some go by the contact type, with males contacts being plugs and female
contacts being sockets, but hermaphroditic connectors and mixed-contact
connectors complicate things.  Some go by fixed vs free, with fixed
connectors
being jacks and free connectors being plugs, but by that convention a
standard
power extension lead has two plugs, but one of those two plugs looks like
a wall socket except it's not fixed to a wall.

Where a coupling mechanism is involved, such as the coupling ring on
a circular connector, some industries will refer to the connector with
the coupling ring as a plug and the connector it mates with as a socket.
The connector with the coupling ring is always free, the mating connector
may be fixed or free.

That's just scratching the surface.  Is the connector at the end of the
cable
a plug or a jack or a socket or a free receptacle or something else?  It
depends
what the specification for that particular type of connector (such as
Chademo) calls it.

It's probably safer to tag the connector type (Chademo, etc.) and not try
to decide whether it's a plug or socket or receptacle or jack.  If
cable=yes/length is given then that connector is on the end of a
cable.
