<div>cable=yes/no/length seems like a great idea. It does

<p>I'd think one end of the cable is fixed to the charging station.
<br>
</p>
<p>Specifying the connector needs to be done for ether a cable or a
fixed connection. <br>

<div>The question then is how to designate that connector. Is
it a plug or a socket?</div>
<div>The answer is not as clear as many think. See</div>
<div><a

</div>
<div>Despite what the Wikipedia article says, the terminology
isn't as clear-cut as</div>
<div>it implies and different industries have different,
conflicting naming</div>
<div>conventions. Within a single industry different naming
conventions may be</div>
<div>applied to different styles of connectors.<br>
</div>
<div><br>
</div>
<div>Some go by the contact type, with males contacts being
plugs and female</div>
<div> contacts being sockets, but hermaphroditic connectors
and mixed-contact</div>
<div> connectors complicate things. Some go by fixed vs free,
with fixed connectors</div>
<div>being jacks and free connectors being plugs, but by that
convention a standard</div>
<div>power extension lead has two plugs, but one of those two
plugs looks like</div>
<div>a wall socket except it's not fixed to a wall.</div>
<div><br>
</div>
<div>Where a coupling mechanism is involved, such as the
coupling ring on</div>
<div>a circular connector, some industries will refer to the
connector with</div>
<div>the coupling ring as a plug and the connector it mates
with as a socket.</div>
<div>The connector with the coupling ring is always free, the
mating connector</div>
<div>may be fixed or free.<br>
</div>
<div><br>
</div>
That's just scratching the surface. Is the connector at the
end of the cable</div>
<div class="gmail_quote">a plug or a jack or a socket or a free
receptacle or something else? It depends</div>
<div class="gmail_quote">what the specification for that
particular type of connector (such as</div>
<div class="gmail_quote"> Chademo) calls it.</div>
<div class="gmail_quote"><br>
</div>
<div class="gmail_quote">It's probably safer to tag the
connector type (Chademo, etc.) and not try</div>
<div class="gmail_quote">to decide whether it's a plug or socket
or receptacle or jack. </div>
</div>

<p><br>
</p>
<p>What ever connector type it should be compatible with the car
connector/cable jack/jill/plug/socket/male/female/etc. So I'd not
worry about it until there is some problem somewhere that requires
a tag, until then leave it off. <br>
