Zusammenfassung:An electronic apparatus, and a storage medium. The electrochemical apparatus control method includes steps (a) and (b): (a) when an internal resistance change rate of the electrochemical apparatus is smaller than a first threshold, performing charging/discharging at a first voltage and a second voltage; and (b) when the internal resistance change rate of the electrochemical apparatus is greater than or equal to the first threshold, raising a discharge cut-off voltage of the electrochemical apparatus by a first raising amount. The internal resistance change rate of the electrochemical apparatus is monitored and the electrochemical apparatus is controlled based on the internal resistance change rate. This improves the cycling performance of the electrochemical apparatus while guaranteeing high energy density of the electrochemical apparatus.
