Title: Measuring Method about Microhm Internal Resistance of Lead-acid Battery
Abstract: A practical microhm internal resistance of lead-acid battery measuring system was designed as a result of the deficiencies in this field. The system was connected by four-wire method and the AC signal of 1k Hz was injected into the lead-acid battery,then the weak signals generated at both ends of the battery was amplified,filtered and transformed to RMS. The system effectively suppressed noise and disturbance,and simplified design,which achieved the measurement of microhm internal resistance of lead-acid battery. The experiments show that the system can be effectively used in the measurement of microhm internal resistance of lead-acid battery,and the measurement results are stable and reliable.
