Zusammenfassung:	A battery diagnostic system includes an interpolation processing unit, a degradation estimation unit, a degradation prediction unit, and an output unit. When a part of the battery load history is missing, the interpolation processing unit interpolates the missing part using the rest of the constituent data. The degradation estimation unit estimates, based on the battery load history, a present degradation state of the secondary battery and a cause of degradation that has brought about the degradation state. The degradation prediction unit predicts, using a predicted battery load, the present degradation state and the cause of degradation of the secondary battery, a predicted degradation state of the secondary battery that will occur in the future upon having been used in the use mode. The output unit outputs the predicted degradation state of the secondary battery.
