The present invention is a deterioration detecting method for an electrochemical device comprising electrodes and an ion conductor, wherein an electrochemical characteristic of the electrochemical device is detected, and an obtained value is then compared with a standard electrochemical characteristic of the electrochemical device to estimate the degree of deterioration of the electrochemical device. Further, the capacity of the device is found based on the detected degree of deterioration, and using this and the output of the device, a remaining capacity of the device is estimated. Accordingly, the degree of deterioration and the remaining capacity of an electrochemical device such as a secondary battery can be accurately detected.
A deterioration detecting method for an electrochemical device comprising electrodes and an ion conductor, wherein an electrochemical characteristic of said electrochemical device is detected, and an obtained detection value indicating said electrochemical characteristic is then compared with a previously stored reference value indicating a standard electrochemical characteristic of said electrochemical device to estimate the degree of deterioration of said electrochemical device.
