PROBLEM TO BE SOLVED: To provide a control method of a battery pack capable of discharging secondary batteries constituting a battery pack reliably up to a predetermined SOC, while shortening the time required for discharge when compared with prior art.SOLUTION: The control method of battery pack 10 having secondary batteries 12A-12N includes the steps of: discharging the battery pack 10 by using a collective electronic load 16 connected therewith, and discharging the secondary batteries 12A-12N individually by using individual electronic loads 18A-18N connected with the secondary batteries 12A-12N, respectively; stopping discharge of the battery pack 10 when the SOC thereof lowers to a predetermined value; and when the SOC of any one of the secondary batteries 12A-12N has lowered to a predetermined value, stopping discharge of the secondary battery the SOC of which has lowered to the predetermined value, and performing stop control in respective secondary batteries. |
