METHOD AND CIRCUIT ARRANGEMENT FOR DETERMINING THE AVERAGE CURRENT CONSUMPTION OF A BATTERY-OPERATED APPARATUS

摘要

The average current consumption of an electronic apparatus is determined in that an energy store C is repeatedly charged and discharged across the apparatus 1 between a set upper threshold value Uso and a set lower threshold value Usu during a typical operating sequence of the apparatus 1 and within a set measuring time T. The number N of charging processes occurring within the measuring time T is counted and the average current consumption is calculated therefrom while taking into account set values.
