CHARGING/DISCHARGING CONTROL DEVICE, BATTERY PACK, ELECTRICAL EQUIPMENT, AND CHARGING/DISCHARGING CONTROL METHOD

There is provided 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 even in a mode of use in which values of currents flowing in charging and discharging states are considerably different from each other. The charging/discharging control device includes: switches (211) and (212) that are connected in parallel on current paths between a battery (10) and a positive (1a) terminal of a battery pack (1); a switching control unit (22) that switches between a charging current path C and a discharging current path D by turning on the switch (211) and turning off the switch (212) during a charging operation and turning off the switch (211) and turning on the switch (212) during a discharging operation; a protective element (24) that fuses the charging current path C when a current value of the charging current path C flowing through the switch (211) exceeds a first fusing current value; and a protective element (25) that fuses the discharging current path D when a current value of the discharging current path D flowing through the switch (212) exceeds a second fusing current value higher than the first fusing current value.
