I am using an OBD monitor and the Carscanner mobile app., to see just about anything you could want. The only thing I am not sure about is the HVB state of Health metric. Not sure how that is determined.
The Carscanner MME profile has 16 screens of data, see below for an example of a DC charge session. I am using a BLE device that does not seem to cause LVB problems when left in the socket.
