A control method including, by a computer, acquiring a current SOC value of the battery, acquiring history information related to a past power consumption amount in the vehicle, inputting the history information having been acquired to a learned model, and acquiring prediction information related to the necessary power amount, determining whether the current SOC value is larger than an optimum SOC value determined in advance for suppressing deterioration of the battery, upon determination that the current SOC value is larger than the optimum SOC value, calculating a target value of an SOC value of the battery based on the current SOC value, the optimum SOC value, and the prediction information, and outputting, to the charge and discharge device, control information instructing to discharge power from the battery to an electrical device outside the vehicle until the SOC value of the battery reaches the target value.

To detect connection between a secondary battery and a charger, determine whether or not a state of the secondary battery is stabilized in a case of detecting the connection, measure a first open circuit voltage that is an open circuit voltage before charging of the secondary battery in a case of determining that a state of the secondary battery is stabilized, instruct the charger to start charging of the secondary battery, detect end of charging of the secondary battery, determine whether or not a state of the secondary battery is stabilized in a case of detecting end of charging of the secondary battery, measure a second open circuit voltage that is an open circuit voltage after charging of the secondary battery in a case of determining that a state of the secondary battery is stabilized, and notify the user of end of charging of the secondary battery.
