US 2024/0201278 A1 · CONSUMPTION METER SYSTEM

Abstract

A consumption meter includes a battery for energy supply and an accumulation module. The accumulation module is configured for accumulating a first quantity over a time period to obtain a first accumulated quantity. The first quantity is based on a product of at least a current drawn from the battery and a duration over which the current was drawn from the battery. The accumulation module is further configured for transmitting the first accumulated quantity at regular or irregular intervals to a battery lifetime estimation module for calculating a remaining battery lifetime on basis of a nominal battery capacity, the received first accumulated quantity and an operating time of the battery. A consumption meter system includes the consumption meter and a battery lifetime estimation module.
