The original goal was: 3.6 - 6.6Kw Leaf Charger (aka OBC) to make it working standalone as a programmable power supply.
By “programmable” power supply I mean at minimum to achieve the following steps on the wish list:
Option A: To power it up from standard Leaf EVSE from 100/200VAC so that there is a continuous fixed DC output.
Option B: A + be able to set up output voltage within the limits built into the hardware /firmware (perhaps limited to acceptable CAN commands);
Option C: A + B + be able to set up output current within the limits built into the hardware /firmware (perhaps limited to acceptable CAN commands); Currently can use my own current regulator up to 6 Amps but would like to utilise whatever Panasonic OBC can offer.
8 May 16 update:
Have built battery emulator (i.e. LBC with 96 resistors and external 240/306 DC applied) and conncted to the harness with VCM and other ECU (except inverter, motor and steering).
In that configuration there is connection over EV-CAN between LBC and VCM but OBC does not power on with EVSE powered from specifically made for purpose 204V AC 3KW transformer.
VCM generates P3196 003 DTC which is according to EVC-(page 287) in 2014 Service Manual prevents normal charging.
There is another EV/HEV DTC P3196 00B (Traction motor Inventer related) which does not seem to be mentioned in SM as charging prohiibiting. Same with another 8:
U0415 009; U1000 004 & 009; B2098 008; P189A 000A; P18A 000A.
In my set up I have not connected Brake ECU (it consumes 3A); steering ECU; Invertor and motor.
Note: I have dismantled Leaf charger down to boards, made some notes of controllers on-board and made a video of that. May upload at some stage if there is interest of what's inside.
12 May 2016 update: project had been parked as priorities have shifted to building other hardware.
