i wonder what's with all the "t's" at the beginning of each line? Maybe it's a time stamp indicator, but it's not clear what it is and doesn't seem long enough.
There are some patterns that appear and repeat, which may be the IDs.
What are you using to capture the data? is the sample rate high enough to catch all the traffic.
Also, what was the car doing during the 2 minute or short capture. Best to limit to short captures of a specific action, eg press and release the brake pedal several times over a short period, or the accel pedal, or shift down and up thru the gears with the brakes on. It's all about trying to detect a pattern that can be related in time to what action you were commanding.
For charging, measure the voltage and current with your meters and make a data scan every 20 minutes or so. This will help you translate the Hex values to engineering units.
