Abstract

A battery-state monitoring system capable of precisely and efficiently estimating the state and service life of a plurality of storage batteries charged with power generated by utilizing natural energy and constantly connected to an equipment is provided. The system includes a power supply control device that detects a current in each battery, an end device that measures temperature, voltage, and internal resistance of each battery, the internal resistance being measured by using two or more kinds of frequencies, and a prime monitoring device that acquires measurement data from the end device corresponding to each battery and issues an instruction related to an operation to the power supply control device and the end device. The prime monitoring device estimates degradation of each battery based on at least one of temperature, voltage, and internal resistance.
