Re: Level 3 Conductive charging..

He's not on the list, but you might ask Tom Stockebrand (stock@swcp.com)
about J1850.  He is working with Avcon (he doesn't work for them) and has
suggested modifications to the wall box, connector and inlet to accomodate
J1850 requirements.

His suggestions to Avcon are:

"Box
"There should be only one offering with a single extra cost option of having
"the 2 Com leads and signal ground brought out to a terminal strip in the
"box so we can get on with hooking up to J1850 signaling."

"The Inlet
"There should be only one, also. It should have the double throw
"proximity switch (Honda). I happen to like the Honda night light idea, too.
"It should also bring out Com1, Com2, and Signal ground. Even though nobody
"will use them now they can't be retrofit and they don't cost much. Smarter
"chargers of the future will need them."

The currently available Avcon PowerPak and Inlet are good for Level 2
charging only.  Maybe we could talk them into supplying future upgrades
to Level 3 for those who want to install the Level 2 system now.

Thanks for the lead on a J1850 knowledgeable person.

Funny you should bring this up as this is the question I currently have 
pending at AVCON.  I sent Kevin Lazarski an email asking him what it would 
cost (if they were willing to do it) to add a terminal strip to the current 
power pack to bring out the signaling and DC power connections for not more 
than 50amps at 200vdc.  I have not received a reply yet.  My interest is in 
controlling an off board "Ugly Box" type charger in my garage.  I will have a 
50 amp Anderson connector available, but I would like to get on the band wagon 
with the Avcon connector.  I see no reason to try to use my own communication 
protocall when one has already been developed.  Besides, in the unlikely event 
that Portland, Oregon has some sort of charging infrastructure, I would then 
be compatible (assuming that the charging stations were conductive).  He says 
that they have a level 3 "connector" available now in prototype tooling and 
will have a full production model next year.  It was not clear to me whether 
the "connector" was the vehicle side or the cord end.  He says that they have 
no plans to get into the Level 3 charger business.
  
Do you suppose we could get Cruising Equipment to add the interface to the 
E-meter such that you could send the shut down signal the same way as Lift 
Lockout?  They would need to add one more parameter so that the vehicle could 
tell the charger what the maximum allowable charge current is (don't want to 
smoke any wiring or fuses).
