Abstract
A deterioration state estimation system of a secondary battery includes: a state variable measurement unit which measures a state variable including an output current and an output voltage of the secondary battery in operation at each prescribed timing; a preprocessing unit which outputs input data calculated on the basis of the measured state variable; and a deterioration state estimation unit which estimates a deterioration state of the secondary battery in operation through a trained deterioration state model using the input data, wherein the preprocessing unit includes a state variable processing unit which sets a unit amount of charge/discharge and a most recent section closest to a current time and one or more previous sections before the most recent section as a desired section based on the unit amount of charge/discharge used for calculating the input data, calculates, as section data, an amount of voltage change based on the state variable for each set section, includes the calculated section data in the input data, and outputs the input data.
