Abstract
본 발명은 무선 전화기의 휴대장치에 있어서 휴대장치의 전원을 공급하는 배터리의 충전을 상태에 따라 신속하게 수행한다. 먼저 외부의 전원 소스와 휴대장치 간을 연결하는 접속수단의 상태를 검사하여 충전전원이 인가되고 있는가 검사한다. 그리고 접속수단과 배터리 사이에 연결되며 수신되는 충전전원을 금속 충전 전류로 발생하며 제1제어신호에 의해 스위칭되어 급속전류를 배터리로 인가하는 급속전류발생수단과, 접속수단과 배터리 사이에 연결되며 수신되는 충전전원을 표준전류로 발생하며 제2제어신호에 의해 스위칭되어 표준전류를 배터리로 인가하는 표준전류발생수단과, 접속수단과 배터리 사이에 연결되며 수신되는 충전전원을 트리클전류로 발생하여 배터리로 인가하는 트리클전류발생수단들을 구비한다. 그리고 제1기준전압을 구비하고 배터리의 충전전압을 수신하며 두 전압의 레벨을 비교하여 제1기준전압보다 낮을 경우에는 제1제어신호를 발생하여 급속충전을 하도록 제어한다. 급속충전을 실시하여 일정시간이 결과한 후 또한 제2기준전압을 구비하고 배터리의 충전전압을 수신하며 두 전압의 레벨을 비교하여 제2기준전압보다 낮을 경우에는 제2제어신호를 발생하는 표준 충전을 수행하도록 제어하고, 두 전압의 레벨을 비교하여 제2기준전압 보다 높을 경우, 즉 충전이 완료한 상태에서는 트리클 충전을 수행한다.In the portable device of the wireless telephone, the present invention quickly performs charging of a battery for supplying power of the portable device according to a state. First, the state of the connection means for connecting the external power source and the portable device is examined to determine whether the charging power is applied. And a fast current generating means connected between the connecting means and the battery and generating the received charging power as a metal charging current and switching by the first control signal to apply a rapid current to the battery, and connected between the connecting means and the battery and receiving Generated by the second control signal is switched to the standard current generating means for applying the standard current to the battery, and connected between the connection means and the battery, the received charging power generated as a trickle current to the battery And a trickle current generating means for applying. In addition, the first reference voltage is provided, the charging voltage of the battery is received, and the levels of the two voltages are compared to be lower than the first reference voltage. After charging for a certain period of time after the rapid charging, and also has a second reference voltage, receives the charging voltage of the battery, and compares the level of the two voltages when the standard voltage is lower than the second reference voltage to generate a second control signal Control is performed, and when the voltage is higher than the second reference voltage, that is, when the charging is completed, the trickle charge is performed.
