Abstract: Provided is a device including an acquisition unit configured to obtain a time taken for a voltage level of a battery in a charge mode to change for each of a plurality of voltage sections, and a prediction unit configured to predict a state of health (SOH) of the battery based on ratio information determined by comparing the time obtained for each of the plurality of voltage sections with a reference time for each of the plurality of voltage sections. When the time taken for some voltage sections of the plurality of voltage sections is obtained by the acquisition unit, the prediction unit corrects the predicted SOH of the battery based on the time taken for the voltage level of the battery in a discharge mode to change.
