Abstract
Official abstract text for this publication.
A battery-monitoring device that monitors a state of charge of each battery cell constituting a battery is provided, including: a voltage detection circuit that individually detects a voltage of the battery cell; a voltage comparison circuit that individually compares the voltage of the battery cell and a threshold voltage, and outputs a signal having a first level when the voltage of the battery cell is equal to or greater than the threshold voltage, and a signal having a second level when the voltage of the battery cell is less than the threshold voltage; and a determination unit that determines the overcharged state of the battery cell when at least one condition is satisfied from among two conditions of: a voltage detection value which is input from the voltage detection circuit being equal to or greater than a threshold; and a signal which is input from the voltage comparison circuit being a first level.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery-monitoring device that monitors a state of charge of each battery cell constituting a battery, comprising: a voltage detection circuit that individually detects a voltage of the battery cell, and outputs a voltage detection value which is a digital signal indicating a detection result of the voltage of the battery cell; a voltage comparison circuit that individually compares the voltage of the battery cell and a threshold voltage, and outputs a s…
