Abstract
A battery internal state estimation apparatus including: an internal state estimation unit, which inputs at least one of measured values obtained by a battery measurement unit at preset sampling intervals including a current flowing through a battery, an inter-terminal voltage, a temperature of the battery, and an ambient air temperature, for estimating, based on the measured values, at least one of a state of charge, internal temperature, capacity, and internal resistance of the battery as an internal state of the battery; and an internal state correction unit for correcting estimated values of the internal state obtained by the internal state estimation unit so that the estimated values are not contradictory at least to qualitative properties of the battery, and outputting the corrected values to an output unit.
