Abstract��View the current situation of lacking teaching contents associated with the battery inner resistance on-line measurement in college physics experiment courses, we designed and manufactured a set of experiment system about battery inner resistance on-line measurement and applied it to experimental teaching. Experiment showed it has achieved good effects. The system used the tetrode method and injected a certain frequency AC signal to battery signals, then made correlation detection to weak mixed battery inner resistance singles. Finally chip microcomputer processed and analyzed the signal measured to implement the battery inner resistance online measurement. The experiment system transferred data to computer, and then the computer saved data and automatic drawn the characteristic curve of battery charging and discharging. This system may obtain high precise experiment result fleetly. Consequently it has a wide application prospect.
