STATE ESTIMATION METHOD AND STATE ESTIMATION APPARATUS

A state estimation method for an energy storage device includes: acquiring, by a first method, a first probability distribution that expresses the state of the energy storage device in the form of a probability distribution; acquiring, by a second method, a second probability distribution that expresses the state of the energy storage device in the form of a probability distribution; and estimating the state of the energy storage device on the basis of the first probability distribution and the second probability distribution.
