Abstract:
A charging/discharging control device that can protect a chargeable/dischargeable battery cell from an excess current state while preventing the device from being increased in scale and from being complex. The charging/discharging control device includes: switches that are connected in parallel on current paths between a battery and a positive terminal of a battery pack; a switching control unit that switches between a charging current path and a discharging current path; a protective element that fuses the charging current path when a current value of the charging current path flowing through the switch exceeds a first fusing current value; and a protective element that fuses the discharging current path when a current value of the discharging current path flowing through the switch exceeds a second fusing current value higher than the first fusing current value.
