NON-TRANSITORY COMPUTER READABLE MEDIUM STORING CONTROL PROGRAM FOR CONTROLLING SECONDARY BATTERY, CONTROL METHOD, AND CONTROL APPARATUS

A control program according to the present disclosure causes a computer to execute: upper limit voltage setting processing for setting, a potential difference between the positive electrode open circuit potential curve and the negative electrode open circuit potential curve at a point corresponding to a state of charge at which an electrical characteristic in which deterioration rates of both a positive electrode and a negative electrode are reduced is obtained as an upper limit voltage; and lower limit voltage setting processing for setting, a potential difference between the positive electrode open circuit potential curve and the negative electrode open circuit potential curve at a point corresponding to a state of charge on a low state of charge side among states of charge at which an electrical characteristic in which deterioration rates of both the positive electrode and the negative electrode are reduced is obtained as a lower limit voltage.
