Just out of curiosity, hat is the spread in the cell voltages that you measured? I have not monitored cell voltages on my Volt, but my measurements on my 2011 LEAF show that 20 mV spread [highest-lowest] is not unusual.
CAN logs from aux DLC port
First off - I don't own a Volt. I am attempting to use the battery from a Volt in something totally different and I'd like to figure out the CAN messages that the Volt sends to the cell balance electronics while it's charging. I believe the information I want is only available on the HV side CAN bus, which is available on the aux DLC port. Does anyone have such a log they can share?
I'm in southern Wisconsin, so if you're within an hour or two I'd love to plug my CAN snooping gear into your Volt and get a log for myself.

A spread of under 5 mV is very good. I wonder if this due to the quality of the LG cells compared to the ones produced by Nissan.Volt stays virtually balanced without any BMS, spread is usually under 5mv
