Deterioration regression curve generation unit generates a deterioration regression curve of each battery by performing curve regression on a plurality of SOHs specified in time series for each battery Coefficient regression function generation unit generates a regression function of a deterioration coefficient using an average travel distance or an average discharge amount per unit period of a plurality of electrically-driven mobile units as an independent variable and using a deterioration coefficient of the deterioration regression curve of each of the plurality of the batteries as a dependent variable. Deterioration prediction unit specifies the average travel distance or the average discharge amount per unit period in accordance with the received change in the travel conditions, applies the average travel distance or the average discharge amount per unit period to the regression function of the deterioration coefficient to specify a deterioration coefficient after the change in the travel conditions, and uses the deterioration coefficient to change the deterioration regression curve of battery mounted in electrically-driven mobile unit.
