Abstract

본 발명은 배터리의 충방전량 표시 방법에 관한 것으로, 종래에는 배터리의 충전시 단지 충전중임과 완료상태를 엘이디(LED)로 표시하므로 정확한 배터리 충전량 및 충전 완료 시간을 예측할 수 없고 또한, 배터리 방전시 현재의 전압 레벨만을 검출하여 3∼4단계로 개략적인 배터리 잔량을 표시하므로 정확한 배터리 잔량을 알 수 없는 문제점이 있었다. 이러한 문제점을 해결하기 위하여 본 발병은 충전시 충전 전위를 검출하여 충전 잔량을 시간으로 표시하고 방전시 잔량을 검출하여 사용 가능 시간으로 표시하도록 방안한 것으로, 본 발명은 충, 방전시 소정 시간 간격으로 배터리의 전압을 검출하여 충, 방전 곡선의 기울기를 구하고 이 기울기로 배터리의 잔량 접압에 따른 시간을 산출하여 표시함으로써 충, 방전 완료 시점을 정확하게 판별할 수 있으며 또한, 배터리의 방전 전량을 시간으로 표시함으로써 배터리의 충전 상태를 정확하게 판별할 수 있다.The present invention relates to a method of displaying a charge / discharge amount of a battery, and in the related art, since only a charging state and a completion state of the battery are displayed as LEDs, an accurate battery charge amount and a charge completion time cannot be predicted, Since only a voltage level of 3 is detected to display the approximate remaining battery level in three to four steps, there is a problem in that the exact remaining battery level is unknown. In order to solve this problem, the present invention is intended to detect the charging potential during charging to display the remaining charge as time and to display the remaining time during discharge as the usable time. By detecting the voltage of the battery to obtain the slope of the charging and discharging curve, and calculating and displaying the time according to the residual pressure of the battery with this slope, it is possible to accurately determine the time of completion of charging and discharging, and also to display the total amount of discharge of the battery in time. As a result, the state of charge of the battery can be accurately determined.
