Purpose: This study analyzes the operating characteristics of a lithium ion capacitor that can be used as a standby power supply in an emergency, and determines whether the standby power supply is abnormal even by measuring the voltage using a linear proportionality characteristic during charging and discharging. The aim is to provide an experimental basis that can be done. Method: As a method for this study, first, analyze the operation principle and characteristics of the existing backup power supply and lithium ion capacitor, and then measure the voltage of the lithium ion capacitor according to the configuration and system block diagram of the induction lamp used in the experiment. We proceed with the test of the measured value of discharge power for each voltage band to check the amount of power held by the battery and the operation test experiment using induction lamps. Results: Just by checking the charging voltage using the linear proportional characteristics of lithium ion capacitors, it provides a basis for accurately inferring the effective operating time of induction lamp lamps. Conclusion: In the event of a disaster, the lithium ion capacitor is used as a spare power supply for emergency induction lamps to prevent complete discharge of emergency induction lamps, to prevent the problem of performing normal operation of the standby power supply, and to use only a simple voltage measurement to reserve power. It was intended to suggest many uses for evacuation equipment application in the future by making it possible to check whether the device is abnormal.
연구목적: 본 연구는 비상시의 예비전원장치로 사용 가능한 리튬이온커패시터의 동작 특성을 분석하고, 충·방전시의 선형비례특성을 이용하여 전압을 측정하는 것으로도 예비전원장치의 동작 이상 유무를 판단 할 수 있는 실험근거의 제공을 목적으로 한다. 연구방법: 본 연구를 위한 방법으로 먼저 기존 예비전원장치와 리튬이온커패시터에 대한 동작원리 및 특성을 분석하고, 다음으로 실험에 사용한 유도등의 구성도와 시스템 블록도에 따라 리튬이온커패시터의 전압 측정을 통해 배터리의 보유 전력량을 확인하는 전압대역별 방전전력량 측정 값 테스트와 유도등을 이용한 동작 테스트 실험으로 진행한다. 연구결과: 리튬이온커패시터의 선형비례특성을 이용한 충전전압을 확인하는 것만으로도 정확하게 유도등 램프의 유효동작 시간을 추론 할 수 있는 근거를 제시하고 있다. 결론: 재난 상황 시 리튬이온커패시터를 비상유도등의 예비전원장치로 사용함으로써 비상유도등의 완전 방전을 미연에 방지하고, 예비전원장치의 정상 작동 수행의 문제가 발생하지 않게 하며, 간단한 전압측정만으로도 예비전원장치의 이상 유무를 확인 할 수 있게 하여 향후 피난설비 적용에 많은 활용도를 제시하고자 하였다.
