Mark,
I've not been into the details yet. My first idea was taking the voltage
readout at the first defined state encountered (e.g. charging / car
switched on), or alternatively by collecting the maximum voltage.
The max would for example be 15.1 for my Twizy and 13.1 for your
roadster. Not sure yet if that's sufficient, maybe building a mean value
over some time would be an option too.
Regards,
Michael
