Nissan Leaf Gen2 (AZE0-2013) EVSE CP signal in CAN
Posted: Sun Jul 02, 2023 5:52 am
Hello,
I am in a process of adding an additional 3kw OBC (not a Nissan Leaf PDB) to run along with the present OBC of my 2013 AZE0 so that I can charge the car with 6kw power. I purchased an EVSE supporting 32A. What I need to do is to make the second OBC to only charge when the CP signal is equal or above 50% of the duty cycle. I know I cannot share the CP with both OBCs. I was looking for a CAN message from the PDM which indicates the cable capacity but I could not find any. I cannot use the max charge limit sent by the BMS or VCM and use it to switch on the second charger without confirming the cable capacity of the EVSE. Is there any expert who knows where should I look in to get an idea?
TIA
