A method of generating data for use in monitoring and controlling the charge status and discharge status of a secondary battery, which is carried out by a microcomputer installed in a secondary battery pack. The data generating method includes calculating a discharge capacity iteratively. The calculated discharge capacity is added to a required full charge capacity determined in a previous period of time, and the sum is determined as a required full charge capacity for each iteration. Also, if an average voltage value for each iteration for the secondary battery is less than a lower limit of the full discharge voltage value, a reference full charge capacity is updated with the required full charge capacity for each iteration.

1. A method of generating data for use in monitoring and controlling the charge status and discharge status of a secondary battery, which is performed by a microcomputer installed in a secondary battery pack, the method comprising:periodically calculating and updating an average voltage value, "avadvol", of a secondary battery; executing one of a charge mode, a discharge mode, and a self-discharge mode according to amplitude and sign of an instantaneous current, "adcur", flowing through the secondary battery; and when the discharge mode is iteratively performed, periodically calculating a discharge capacity, "DCR", and updating a required full charge capacity, "s_dcr", for each iteration with the calculated discharge capacity and, if the average voltage value, "avadvol", for the present time drops below a lower limit of a full discharge voltage value, "s_edv0", updating a reference full charge capacity, "f_c_capac", with a required full charge capacity, "s_dcr", for each iteration.
