On the other hand, when using the mobile station 2, the power switch 13 is turned on,
When the call circuit 10, the wireless circuit 11, the control circuit 15, etc. operate,
Since the rechargeable battery 14 is consumed, the count circuit 25 counts down. In this way, the counting circuit 25 changes the rechargeable battery 14
The value obtained by counting the charging / discharging current value of is sent to the correction circuit 26.
Further, the detection circuit 19 constantly detects the terminal voltage of the rechargeable battery 14, and sends the information to the correction circuit 26.

That is, even though the terminal voltage value detected by the detection circuit 19 is a voltage value indicating the fully charged state of the rechargeable battery 14, if the count value of the count circuit 25 is smaller than that value, the count value is added. , The terminal voltage value detected by the detection circuit 19 is 14
If the count value of the count circuit 25 is larger than that value, the count value is subtracted. Information of the corrected count value is sent to the control circuit 15. The control circuit 15 manages the capacity based on the corrected count value. That is, when the rechargeable battery 14 is charged, the charging current control circuit 28 is controlled to control the charging current. Therefore, since the charging current can be controlled with high accuracy, the rechargeable battery 14 can be charged in a short time, and overcharging can be prevented.

When the call is continued, the wireless circuit 11, the call circuit 10, and the control circuit 15 continue to operate as described above, the rechargeable battery 14 is exhausted, and the information is sent to the control circuit 15. When it is desired to know the remaining capacity of the rechargeable battery 14, the control circuit 15 is operated by operating a key switch or the like, the display means 27 is controlled in the same manner as described above, and the number of LEDs corresponding to the corrected count information is displayed for a certain time. Alternatively, it may be displayed quantitatively. At this time, with use,
The number of LEDs lit is less than when the call started. Then, when the number of lit LEDs is 1, it is possible to display the reduced voltage by light or sound.
