Provided is a battery residual value determination system capable of easily and accurately determining the residual value of a battery. The battery residual value determination system includes: a battery information reception unit that receives information on the voltage, the current, the temperature, and the period of time elapsed from the time of manufacture of a battery; a first residual value determination unit that determines a first residual value indicating the SOH of the battery; an attenuation function determination unit that determines an attenuation function which indicates a time-dependent change of the SOH specific to the battery and is used for correcting the first residual value of the battery; and a second residual value output unit that determines and outputs a second residual value obtained by correcting the first residual value by using the attenuation function according to the period of time elapsed from the time of manufacture of the battery.
