Abstract
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.
