    摘要： In a charging/discharging unit provided with: a lithium secondary battery, a voltage detecting sensor for detecting a voltage and a current detecting sensor; the charging/discharging control unit is further provided with a controller, and a discharging element for performing a constant voltage discharging operation of 3 V. A voltage, V0, of the battery when a discharging operation is terminated (t=0) is measured by the voltage detecting sensor. If V0≦3.6 V, within a rest time during which the battery is not charged/discharged until a next charging operation, a voltage, V1, of the battery when a time, t1, has elapsed is measured by the voltage detecting sensor. If this voltage charge is in a range of V1−V0≧0.2 V, then the constant voltage discharging operation of 3 V is carried out for a time duration longer than or equal to 1 hour.
