PROBLEM TO BE SOLVED: To provide a battery unit capable of simply monitoring operating conditions of all batteries. SOLUTION: This battery unit is provided with a battery unit 4 formed by parallel connecting a plurality of battery subunits 3a-3c formed by connecting a plurality of secondary batteries and a battery subunit circuit breaking means in series, and a voltage monitoring means (control base board 5) to monitor a voltage applied to one or more secondary batteries equipped by the battery subunit in each of the subunits 3a-3c. When the voltage monitoring means detects an abnormal voltage on at least one battery subunit, charge and discharge of the battery subunit having that abnormality is stopped by a subunit circuit breaking means.
