More Information
Summary:According to one embodiment, a determination device relating to a plurality of batteries connected in series is provided. The determination device includes a processor. The processor determines a deterioration variance among the batteries, based on first voltage data indicative of a maximum voltage which is greatest among voltages of the batteries in each of measurements in a plurality of periods in charge or discharge of the batteries, and second voltage data indicative of a minimum voltage which is least among the voltages of the batteries in each of the measurements in the periods.
