化を防止できる。FIG. 2 is a diagram showing an example of the charge / discharge characteristics of the battery unit of the portable terminal device according to the present invention. The forced discharge will be described in more detail with reference to FIG. The determination unit 11 determines that the charge capacity value of the battery unit 17 is a capacity reference value,
For example, about 90% or more of the maximum allowable capacity (C), in FIG.
0.9C, and a period exceeding this capacity reference value (full charge period), in FIG. 2, a period I is a time reference value, for example,
If it is determined to be longer than about three months, an instruction is issued via the control unit 18 to force the battery unit 17 to be forcibly discharged, and the discharging unit 16 forcibly discharges. In general, it is known that the lithium ion battery starts to deteriorate after a full charge period of 3 to 6 months. At this time, the method of measuring the period I is based on a method of resetting the timer unit 14 every time charging is completed and measuring the time. Next, the determination unit 11 determines that the charge capacity of the battery unit 17 is set to the second capacity reference value, for example, about 50% of the maximum allowable capacity, and 0.5 in FIG.
If it is determined to be smaller than C, an instruction is made via the control unit 18 to terminate the forced discharge, and the forced discharge of the discharge unit 16 is stopped. The capacity of about 50% of the maximum allowable capacity is the deteriorated capacity due to the capacity decrease due to the self-discharge of the battery,
For example, the capacity has a margin for 15%. According to the above-described method, the period I during which the lithium-ion battery is left in a fully charged state can be limited to, for example, less than three months, so that deterioration due to long-term storage at full charge can be prevented. .
