Abstract

A battery unit includes at least one battery module that includes at least one battery cell, at least one battery heat flow detector that detects a heat flow of the at least one battery cell and the battery unit, at least one reference heat flow detector that detects a heat flow of the battery unit as a reference heat flow, and a battery state estimator that estimates a state of the at least one battery cell, based on a heat flow of the at least one battery cell given by subtracting the reference heat flow detected by the at least one reference heat flow detector from the heat flow detected by the at least one battery heat flow detector. The at least one reference heat flow detector is disposed in the battery unit at a location where temperature fluctuation is small and heat capacity is large.
