Good question. Since all the current in the car (except for the starter motor) goes thru the gauge I am thinking it functions the same way an ammeter does. Packard may have chosen to refer to it as a charge indicator as a CYA because there is no scale and the needle swing may not be linear or proportional to actual current.

Interesting the 47 labels the gauge BATTERY, no indication on the 48-50 gauges, the 55 has it labeled AMP and the 56 calls it GEN. Parts book calls it an ammeter.
