Abstract

A battery state estimating device estimates a battery state in a battery module having a plurality of secondary batteries. The battery state estimating device is configured to be able to change a number of targets which is a number of the secondary batteries subject to estimation of the battery state of the secondary battery based on a specific value acquired from the plurality of secondary batteries, or the battery state estimating device is configured to be able to change a calculation formula for estimating the battery state of the battery to a calculation formula with a small calculation load.
