A microcontroller-based battery test system with energy recycling technique

In this study, a microcontroller-based battery test system for power battery is realized. This system is composed of a microcontroller, a sampling circuit, a human interface and a resonant load. The proposed resonant load with wide-range slew-rate and continuous loading function is used to verify the feasibility of the battery test system and can recycle energy in test procedure. Furthermore, the proposed system can set battery parameter and loading current according to battery specifications by human interface. The proposed system has both low cost and portable feature. Finally, this work provides complete model analysis, and test results to verify the theoretical predictions.
