Abstract

무선전화기의 과방전 방지 방법에 관한 것으로, 특히 무선전화기의 휴대장치에서 배터리 과방전에 의한 이상동작 발생을 방지하는 과방전 방지방법에 관한 것이다.The present invention relates to a method for preventing over-discharge of a radio telephone, and more particularly to an over-discharge prevention method for preventing abnormal operation caused by battery over-discharge in a portable device of a wireless telephone.

무선전화기에서 저전압이 검출된 후 설정된 일정시간이 경과되기 이전에 극 저전압으로 떨어지게 되면 충전배터리는 완전 방전 상태가 되어 충전이 불충분하게되어 충전배터리를 사용할 수 없는 상태가 되어 수명이 짧아지고, 또한 휴대장치의 메모리에 기억된 데이타가 유실되어 충전배터리를 교체하더라도 무선전화기를 사용할 수 없는 문제를 해결하기 위해 충전배터리의 상태를 체크하여 저전압상태가 될 시 재충전경보를 발생하여 사용자에게 알리고, 극저전압상태가 되면 설정된 시간에 관계없이 충전배터리의 전원을 차단한다.After the low voltage is detected in the radiotelephone, the battery falls to an extremely low voltage before the set period of time has elapsed. The battery becomes fully discharged and the battery becomes insufficiently charged. In order to solve the problem that the cordless phone cannot be used even if the rechargeable battery is replaced because the data stored in the memory of the device is lost, the user can check the state of the rechargeable battery and generate a recharging alarm to notify the user when the low voltage is reached. Turns off the rechargeable battery regardless of the set time.
