Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To eliminate a phenomenon in which degradation in a secondary battery rapidly progresses, without causing a decrease in processing speed, in secondary battery control.SOLUTION: In a power storage system including a secondary battery, a secondary battery control system includes: means for detecting a measure indicating the degradation state of a positive electrode; means for detecting a measure indicating the degradation state of a negative electrode; means for calculating the difference between the measure of the positive electrode and the measure of the negative electrode; means for determining a sign for the difference; and means for changing operation conditions of the secondary battery according to the sign.SELECTED DRAWING: Figure 3
