Abstract :
This paper introduces the principle of valve regulated lead acid batteries (VRLA) on-line monitor-internal resistance measurement of monocell´s transient twice constant current discharge. Hardware design and software program based on this principle were analyzed in detail, and experimental results were put forward. The system, with the function of remote control and measurement, is convenient to realize the automatization of invalid battery detection.
