Abstract:
[Problem] To evaluate the state of a storage battery using measurement data obtained at the time of charging the storage battery. [Solution] This storage battery evaluation device is provided with a charging control unit which switches the charging current of the storage battery being charged with a first current to a second current, and a state estimation unit which estimates the state of the storage battery on the basis of a feature value of the change in voltage and/or charging amount of the storage battery resulting from switching the charging current to the second current.
