First Claim
Patent Images
1. A battery state estimating apparatus comprising:
- 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 from 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.
