PURPOSE: An apparatus for diagnosing deterioration of an emergency power system is provided to prevent the deterioration by monitoring the soundness of the emergency power system.

CONSTITUTION: A relaying circuit(4) is connected to each cell of a storage battery(3). A constant current source(5) is controlled by a MCU(11) and is connected to the relaying circuit. A main input/output unit such as an LCD and a keypad is connected to the main control unit. An MPU(1) of main control unit outputs a selection control signal to operate an n-th relay connected to the storage battery. The MPU outputs a clock pulse signal to operate the constant current source. The constant current generated by the constant current source is applied to the storage battery through the relaying circuit. An auto scaling circuit(7) is used for amplifying characteristic data of the storage battery. The amplified data are converted by an A/D converter(6). Internal impedance of the storage battery is calculated by an impedance calculation program. State history data of storage battery cells are calculated by a program within the MPU. The characteristic data, the internal impedance, and the state history data are stored in the memory.

(KO) 비상전원설비 또는 통신망전원설비등에 축전지시스템이 많이 사용되고 있고 이를 효율적 관리하는 것이 중요한 문제로 대두되고 있다. 대개 축전지를 포함한 비상전원장치의 신뢰도를 확보하기 위하여 중요한 설비의 경우에는 일반적으로 3년 등 일정한 주기마다 축전지시스템전체를 무조건 교환하는 방식을 사용하여 왔으므로 이때 정상적인 축전지도 동시에 폐기되는 경제적 손실이 발생하고 있다.
