I'm not sure if this is an appropriate place to ask this question, but here goes.

I have been playing with an Android app called MyGreenVolt to gather some interesting statistics from Victor during my daily drives. One of the data points collected by this app is titled 'KWH_USED'. Basically the app logs and performs calculations on data available through OBD-II.

What I see is that KWH_USED at the start of a trip with a full charge is about 83.1xxx. The number decreases throughout the drive to finish at my destination at about 21.5xxx. A fresh start with a charged battery repeats the cycle again.

Do you have any guesses or knowledge about what this data point may actually be?

Without knowing more, sounds like it's actually the SoC% of the battery. 83% when it's "full", 21% when it's "empty".

Thanks, that makes sense to me. The label is what was throwing me off.

Yes, that's labelled incorrectly. It's SOC%.

2013-15 should be ~83.5% full and ~18.8-19.2% empty (though engine may turn on at a higher % if energy demand requires it)

Before syncing with the OBD2 reader, in portrait display mode, the bottom left of the MyGreenVolt app’s Dashboard on my android phone shows:

0.0 m/kWh
0.0 kWh/100 mi
0.0 kWh used
0.0 kWhR (0%)
SoC: 0.0% (0.0%)

I note that on my android display, it shows kWh used, not KWH_USED. The app needs a better user manual to clarify the significance of the various numbers. At the top of the dashboard is a row of icons, at the far right of which is one that looks like three dots stacked one upon the other. Tapping that gives you an option of changing the screen display white/black. Also, in the landscape mode display, these number appear in the bottom center. Choose the options that makes it easier to see the data on your screen. The Settings menu enables you to select your Volt’s battery size, which is used for the SoC numbers for relative % of the useable window (0% - 100%), and absolute % of actual battery capacity. This is the number that reflects the window of useable power (I usually see ~22% - ~87% for my 2012 Volt’s 16 kWh battery’s 65% window).

Thank you for that. Actually, I was viewing the PID data in a spreadsheet imported from the .csv the app saves. In that spreadsheet, the column header is "KWH_USED".
