Title:
BATTERY-STATE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/069423
Kind Code:
A1
Abstract:
A battery-state monitoring system capable of efficiently and highly accurately estimating the battery state and life of each battery, while suppressing voltage variation between batteries, in a large-scale power supply system having a plurality of batteries filled with power generated using renewable energy. The battery-state monitoring system has: a control/power supply device (50) for detecting the current of each battery (41); extension devices (30) for measuring the temperature and voltage in each battery (41), and the internal resistance of at least two types of frequencies of each battery (41); and a host monitoring device (10) for obtaining measurement data corresponding to each battery (41) from the extension devices (30), and issuing a command pertaining to the operation of the control/power supply device (50) and the extension devices (30). Therein, the host monitoring device (10) estimates the deterioration of each battery (41), on the basis of one or more values selected from among the temperature, voltage and internal resistance measured by the extension devices (30), and the DC resistance of each battery (41), and lowers the voltage of the batteries having a voltage higher than a prescribed value, by transmitting a constant current from the state measurement device.
