BATTERY STATE ESTIMATING DEVICE

摘要

Battery state estimating device includes: measured value acquiring unit for acquiring a measured value in a predetermined measurement period of the time-varying battery state of battery after charge or discharge; model function determining unit for determining, based on the measured value, the function forms of a plurality of model functions for modelling the battery state; multiple prediction unit for predicting the variation of the battery state using each of the plurality of model functions whose function forms are determined; and estimating unit for calculating an estimated stable value of the battery state on the basis of the result by multiple prediction unit.
