Abstract
An emergency power diagnosis system measures the exact value of impedance voltage (Vis) from an AC actual waveform (V) includes circuits and software operable to measure the effective resistance of battery internal impedance to determine the expected life of a battery string. The system is configured to determine the cause of aging progress in advance and determine by unmanned monitoring the real-time status of emergency power system at a remote site.
