Abstract
A battery monitoring device according to an embodiment monitors a state of a secondary battery block including parallel cell blocks connected in series each of which includes battery cells connected in parallel. A calculator calculates direct-current internal resistance values of the parallel cell blocks based on a differential current between first and second current values detected by a current detector, voltages of the parallel cell blocks corresponding to the first and second current values detected by a voltage detector. A determiner performs anomaly determination for the parallel cell blocks from the direct-current internal resistance values of the parallel cell blocks and a maximum value of the direct-current internal resistance values of the parallel cell blocks.
