They don't even have anything about pulling the cord all the way out before
plugging in. I only pulled out enough for my Soul EV so it wouldn't be a
trip hazard. Before my flight back to Portland, OR, I instructed the car to
start charging. When I arrived it had been charging for 2-3 hours. The cord
outside the reel was barely warmer than ambient but the portion of the cord
still in the pedestal on the reel was significantly warmer. I'm not sure
what the temperature rating of the cord was but it did concern me a little.
I think they are 16A stations based on the time to charge given by the EV
display (I wish it had a menu displaying all the technical info).

The for the reel in my Gizmo I always pull the cord out all the way before
charging.

My 40A 40ft JLong extension cord is less than 18 lbs. Besides, with a Curb
Weight of 3,289 lbs and a Gross Weight of 4,321 lbs you will not be able to
detect a range penalty especially considering it is less than 0.55% the
weight of the car. That 18lbs at 60mph is only 2873J of KE or 0.8Wh of
energy, over half of which can be captured back with regenerative braking.
Conservatively my Soul EV+ consumes 285Wh/mi. Even if I didn't use
regenerative braking I'd have to accelerate to 60mph over 356 times to use
up 1 mile of range, with regen it is easily double that number.

The extra weight argument is merely academic. Especially considering that
the 120V EVSE included with the vehicle could use the same cord. The only
extra weight being the extra copper to handle the OBC max charge rate, the
inlet on the 120V EVSE box and the extra handle on the extension cord. The
weight difference is going to be only a couple of kg or less.

As for convenience, those who charge at home likely will have an EVSE with
cord installed and only would need to use the charge cord when at a public
station.

It could also be done by having a reel on the charging station, so the 
cord gets reeled in and locked inside when not in use.

I have always carried an extension cord in my EVs anyway, in case I need
to opportunity charge somewhere. Having it built into the car on a reel
would actually be a convenience.

IMO, the main reason that current EVSEs (the old inductive chargers too) 
were designed that way was to make them resemble gasoline pumps.

Similarly, the annoying and totally unnecessary brake-off creep was built 
into many (most?) EVs for the same reason - so they act like "normal" ICEVs 
with automatic transmissions.  People are afraid of change, so they hobble 
anything new to make it resemble the old.

So, put a 20lb cord plus take up reel in every EV?  Using lots of space, and 
adding weight to every EV?

David,
You are describing the European charging stations that have a Mennekes
connector on the pedestal and every EV comes with the charging cord that
plugs into that Mennekes connector and into the EV.
Only the US situation is that the cord is attached to the station.
Apparently that is not always beneficial.

I know it would be more inconvenient but why doesn't every EV have their
own J1772 extension cord and the EVSE just have a socket like on the
vehicle? This way no cord is left at the charge station and every car
can lock the cord to the car. When a car is done charging another
vehicle can plug in and leave the first car's cord on the ground with
the protective cap on.
