I recently bought a used 2019 with the recall fix. I am really enjoying driving it, especially in L mode. I got a ODBII adapter and Torque Pro and made a log. Can someone let me know what PIDs I should log to try to calculate battery capacity and stability. Is "!Battery - Pack - Capacity kWh estimated 2019+(kWh)" at all accurate?
I think I need to get the max voltage difference between cells, but am not sure how to get this.

It is based on the GM Ah PID, so it is Telek's best current guess. The Ah PID is correct. It varies up an down a bit due to temperature, impedance, etc, but will generally move down over months and years.

ok, downloaded csv and astro file but your instructions say "find the CSV file that you downloaded " What file you talking about ? I didn't download any file.

It isnt Jerry Duke's instructions. That is Telek's website.
The instructions are very clear and step by step on that website.

If you get stuck, go to this thread --> Chevrolet Bolt OBD2 PIDs

thanks. i'll wait till torque comes out with something easy to use. this makes no sense.

I tried to get the difference in cell voltage. I get the same value (3.66000152) for both the following PIDs.
*Battery - Cell - Maximum Voltage(V)
*Battery - Cell - Minimum Voltage(V)

For !Battery - Cell - Average Voltage(V), I get 3.66994739.
Can anyone help me make sense of this?
