Inside the EVSE

maybe 8A also.

jumpers on the borrd could ce easily set at install,
or a rotary switch wired ti the jumper heder would
make the unit nicely portable.

Schneider... looks nice and clean.

Interesting, the Nissan-branded Aerovironment EVSE I won and received today doesn't have the metal shield that is in kolmstead's post (http://www.mynissanleaf.com/viewtopic.php?p=39932#p39932" onclick="window.open(this.href);return false or the pics here earlier of it.

The manual appears to be the same revision as the scan at http://www.mynissanleaf.com/viewtopic.php?p=39867#p39867" onclick="window.open(this.href);return false;. Perhaps I should take some pics of the internals of mine before I sell it? I was surprised (but understand why now) that the lid/front cover wasn't attached at all. That's what the 9 supplied screws are for...

Built May 2012 powering a I-MiEV

Leviton EVR-Green 160 EVSE Level 2 240 volt 16 amps

Have had this "charger" since August 2011. Easy to install, and has been trouble free.

Main board


Membrane switch and voltage adjust pots.


J7 Daughterboard


Unpopulated Dot Matrix, Wireless connections


Ground fault detection sensor

I used to have a Leviton until I built my own. I see that they use the Blue proxy switch wire. My Leviton EVSE shut down when the switch was pressed.

The relay looks like the one Chris uses.

Glenn,

The relay used is similar but it seems to have more contacts, we use a DPST in OpenEVSE, this one looks like it could be DPDT... I have a Schnieder EV link as well as the portable OpenEVSE I built.

You are right. I overlooked the small white wires.

Its hard to tell but I think the blue wire is the pilot not proximity. The yazaki cables use blue for pilot and do not have proximity brought out through the cable.

The blue wire is the pilot signal, there is no proximity wire entering the enclosure.

The relay is a DPST Tyco T92P7A22-240 with a 240 vac coil.
The small wires are attached to a male spade lug connector which is part of the main power female connectors.


What I really found interesting was the daughter-board attached to J7, which seems to be a way of passing a controlled current on the protected side of the GFCI coil.

That IS the same relay as many OpenEVSE Builders are using except we use the 12V coil so the EVSE can be L1 or L2.

The wire to J7 is most likely there to read the voltage on the line for a stuck relay test. OpenEVSE is doing the same thing with the advanced power supply. Do you have a source for the spade lug connector, I could use a bunch of those...

Did it have a delay before it shut off the EVSE? You'd want to give the charger time to stop drawing before deactivating the EVSE relays.

They are available from Digikey and several other electronics parts suppliers. Usually listed as piggyback terminals.

Thanks Barbouri, wish I had known about those before I spent time jamming the #10 and #22 AWG into a single terminal on each of the four relay contacts, this is much better and easier to maintain as well.
