摘要： A control device that controls discharge of a nonaqueous secondary battery in order that discharge electric power of the nonaqueous secondary battery does not exceed an upper limit value includes a current sensor and a controller. The controller calculates an evaluation value for evaluating a first deterioration component based on a discharge state detected by using the current sensor. The first deterioration component is a component that reduces output performance of the nonaqueous secondary battery due to an imbalance of ion concentrations in an electrolytic solution caused by discharging the nonaqueous secondary battery. The controller integrates a value obtained by subtracting a correction coefficient from a first integrated value obtained by integrating the evaluation values in past, which exceed a target value, and the evaluation value at present, which exceeds the target value, to calculate a second integrated value. When the second integrated value exceeds a threshold value, the controller reduces the upper limit value.
