KR960016212A - Discharge prevention device and method of wireless telephone - Google Patents

Abstract

The present invention provides a wireless telephone mounted with a rechargeable battery in a portable device; A charge detector for detecting whether a rechargeable battery is charged; A voltage detector detecting a voltage; A wireless transceiver for detecting whether a telephone is in use; A control unit for outputting a control signal; A dial unit to receive a control signal of the controller; A warning sound generating unit; A screen display unit is provided. In addition, in the discharge prevention method of the radio telephone; Determining whether charging is in progress; Detecting a voltage; Detecting whether a call is being made; Generating a warning sound and lighting a discharge lamp, and displaying a text for warning of charging. Therefore, the present invention can prevent the portable device of the radiotelephone from being completely discharged by simply setting a change of algorithm and a hardware function to grasp the state of charge of the rechargeable battery built into the portable device of the radiotelephone.
