In this study, a microcontroller-based battery test system for power battery is realized. The system is composed by a microcontroller, a sampling circuit, a human interface and a resonant load. The proposed resonant load having wide-range slew-rate and continuous loading features is used to verify the dynamic characteristics of the power battery thus can recycle energy in diagnostic process. Furthermore, the system can provide loading current according to battery specifications. The proposed system has both low cost and portable feature. Finally, this work provides analysis of operation principle, and test results to verify the theoretical feasibility.
