Dear all,

Mouli asked a separate thread for this topic.
I have two questions concerning the case of a PC with a battery:

  1. How to model it using the parent-chlid approach
  2. How to apply metering domains

sub-issues are:

  1.1 If the PC reports directly to the management system
         (as PCs usually should do) is then the PC parent of the battery?
  2.1 If the PC runs on battery, do we have to report positive
         power values for the PC and negative power values 
         (indicating a generator) for the battery? If we don't do so,
         we may double account energy that first charged the battery
         and then powers the PC.

Thanks,

    Juergen
