Abstract
A charging time estimation device includes a cell temperature information acquisition unit, a cell capacity information acquisition unit, a current value information acquisition unit, a deterioration state information acquisition unit, a basic estimated value calculation unit, and a charging-required time calculation unit. The charging-required time calculation unit performs correction on a basic estimated value of a constant current charging time and a basic estimated value of a constant voltage charging time by using current value information and deterioration state information, and calculates, as a charging-required time, the sum of the basic estimated value of the constant current charging time after the correction and the basic estimated value of the constant voltage charging time after the correction.
