This is my first post so please direct me genteelly if I have broken any rules.
I just installed a 40 amp service in my garage in anticipation of installing an EVSE. Rooting around the Internet, I found some information about what is contained in the EVSE: a J1772 cord and line, a container box, a DPDT relay, a 12Vdc signal voltage, various led indicators, a logic unit and a 1K resistor. I believe that's all...if there is more, please let me know.
Additionally, I believe the logic from the Leaf charger drives the EVSE with a series of voltages that work in conjunction with the resistor and 12vdc signal through the use of a voltage divider in the car: at 12volts the EVSE relays are open and no AC flows, at below 6volts, the relays close and AC flows to the charger; when the charger has finished its work, it produces a 9volt signal that opens the relay.
So it looks like the EVSE has a logic circuit to control the relay, driven by voltages from the Leaf's charger.
Question: Does anyone have a schematic and/or a parts list of an EVSEor knows where to find them?
