Abstract:
1. A charging/discharging control device that controls charging/discharging of a battery arranged in a battery pack and obtained by connecting at least one chargeable/dischargeable battery cell in series, comprising: first and second switches that are connected in parallel on current paths between the battery and an external terminal of the battery pack; a switching control unit that switches between a charging current path and a discharging current path by turning on the first switch and turning off the second switch during a charging operation and turning off the first switch and turning on the second switch during a discharging operation; a first protective element that fuses the charging current path when a current value of the charging current path flowing through the first switch exceeds a first fusing current value; and a second protective element that fuses the discharging current path when a current value of the discharging current path flowing through the second switch exceeds a second fusing current value higher than the first current value.
