/My solution was to use a 4pin twist-lock connector, it's in parallel to the J1772 socket. The pilot from the J1772 is connected to the neutral pin on the twistlock through a diode and load resistor. In order to enable the EVSE there has to be a dummy plug with a jumper from Neutral to GND in the twist-lock. That way no pins are exposed when the EVSE goes live.
Since the J1772 socket is is idiot proof I'm not really concerned that there is live voltage on those pins when I connect to the twist-lock. / I have both a J1772 and a 50A Marinco connector. At first I put a triplet of 75A Anderson connectors on each cord to connect the charger (through an energy meter) to one or the other. That got to be a pain pretty quick, so I installed a 240V/50A DPDT relay with 240VAC coil: http://www.onlinecomponents.com/magnecraft-schneider-electric-w199apx15.html?p=29816731 The J1772 is the default, the relay clicks to the other position when I plug in through the Marinco. The 50A permits me to charge at higher power than the J1772 since it is only a 40A one, and most EVSE's are 32A max. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/J1772-Thoughts-tp4667454p4667781.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
