Abstract:
A battery state estimating apparatus is provided with: an acquirer configured to obtain a complex impedance of a battery; a calculator configured to calculate a ratio of a variation of a predetermined feature amount regarding the complex impedance; and an estimator configured to estimate a charge amount of the battery on the basis of the ratio of the variation of the predetermined feature amount with respect to an integrated current value, which is an integrated value of an electric current flowing through the battery.

Claim (Index 5):
The battery state estimating apparatus according to  claim 1 , wherein\n said calculator is configured to calculate the ratio of the variation of the predetermined feature amount by using, for the predetermined feature amount, a slope of a straight line connecting an origin on a complex plane and a value of the complex impedance at a first predetermined frequency, the complex plane having an axis that is a real component of the complex impedance and an axis that is an imaginary component of the complex impedance.
