Claims

A battery that is charged when connected to a charger built into the main body of the phone, a charging state detector for detecting whether the charger is connected to the charger and determines whether to charge the battery, and receives power from the battery to perform a normal cordless phone function. A cordless telephone having a cordless telephone circuit as a section and a handset, comprising: a switch for interrupting a charging voltage of a battery flowing from a charger of the main body; A switch controller to control on / off of the switch; A voltage detector for detecting a voltage of the battery to detect whether the battery is above a predetermined voltage; A wireless telephone having an automatic charging cutoff function, which controls the operation of the entire device, and in particular, comprises a micom for controlling the switch control unit according to the charging voltage state and the charging time of the battery.

The switch of claim 1, further comprising: a light emitting diode having a power supply voltage input to an anode side through a resistor and a cathode side connected to the switch controller; And a transistor configured to transfer a voltage from the charger to a battery when the light of the light emitting diode is sensed.

The method of claim 1, wherein the microcomputer determines that the battery is being charged from the charging state detecting unit, and turns off the switch when the charging voltage is greater than a predetermined voltage and a predetermined charging time has elapsed, and the battery is being charged. Or the charging voltage is not greater than a predetermined voltage or a predetermined charging time has elapsed, wherein the switch is 'on'.
