Abstract
A condition determination device for determining a condition of an electric storage device includes a current detector, a voltage detector, and a controller. The controller is configured to: determine a level of a first electric factor based on at least one of a charging current detected by the current detector and a charging voltage detected by the voltage detector; obtain first charging time while the level of the first electric factor is constant; determine a level of a second electric factor based on the charging voltage detected by the voltage detector; obtain second charging time while the level of the second electric factor is constant; calculate a determination value based on the first charging time and the second charging time; and determine a condition of the electric storage device based on the determination value.
