Excellent information, I am especially excited about using the Chademo discharge you mention. This is on my list to do as well. I am presently using a bank of lights, it gets bright and warm.
I am working on a GEN2 pack and running it standalone. It works and runs the car just fine. I use 1DB to manage cut off of charging at this point.
I am manually turning on the relays thru the relay block connector and I have the 12volt and ignition connections as noted.
I then use both the regular CAN data (0x1DB for current voltage/current, 0x1DC for allowable discharge current, 0x5BC/0x55B for remaining GIDs/SOC) and the engineering data (0x79B group 2 for cell voltages) to manage cutoff criteria.
I am using the 1DB and it provides live data during charge and discharge all the time. I have not looked at "allowable discharge". I am however reading 0x5BC/0x55B for remaining GIDs/SOC but it remains static at the value read when started up via ignition on. I have to cycle the ignition to get a fresh value.
The 79B commands capture data for cell voltage, shunts and temperature. I am also using the Group 3 commands for min/max/avg but these also do not refresh when running. I want to use these group 3 commands to determine battery discharge cut off and assist with charging as noted above currently using the 1DB command.
I note that the Leafspy pro app appears to exhibit the same behavior when connected to the pack only.
I need to make a fresh recording of the data exchange between the full car, the leafspy and the pack.
I added 11A (heartbeat) into my code last night using all 4 variations thinking that it might trigger a refresh.

0x11A 8 0 80 0 AA 80 0 3 AA
I will test this today ... if it stops raining ... or at least slows down. The rainfall here is at least double the seasonal averages and the car is outside, have a a small river running down my drive way.
Thanks for the tip on the wake up, that of course makes sense, I will try that next and let you know.
P.S. I am planning to return to work on the Standalone OBC/PD charger this week if I can solve this issue.
Thanks for your continued support.
