Claim One:
1. A battery learning system, wherein an output value at a predetermined characteristic step point set in advance is used as a characteristic value for an output characteristic of a battery that operates through an electrochemical reaction, the output characteristic is plotted as an output characteristic curve by connecting each discrete characteristic value, and the characteristic value acquired by actual measurement is learned to thereby update the output characteristic curve, the battery learning system comprising: an acquisition device that acquires an actual characteristic value of the battery; an impedance value acquisition device that acquires an impedance value of the battery; a storage device that stores the output characteristic curve of the battery; and an update device that updates, based on the acquired actual characteristic value, the stored output characteristic curve on a predetermined condition set in advance, the update device comprising, a judgment portion that judges whether or not an acquiring interval between acquisitions of the impedance value achieved by the impedance acquisition device exceeds a predetermined threshold interval set in advance, and a prohibition portion that prohibits updating of the output characteristic curve when the acquiring interval is judged to exceed the threshold interval by the judgment portion.
