Abstract—Charging-discharging converter for battery cells is widely used in modern industry to measure the performance of the battery. With the rapid development of the technology of switching power supply today, converters with high efficiency and small size are becoming more and more important. This paper proposes a novel half-bridge converter for battery charging-discharging based on Thevenin equivalent model with high efficiency and simplified structure. The control circuit and detecting circuit are also analyzed in the main system. The simulation results from two series of 28V, 800Ah lead-acid battery cells are given to verify the stability and reliability of the converter.
