Zusammenfassung:A cascaded half-bridge active capacitance equalizer disclosed by the present invention comprises an equalization circuit, a module driving circuit, a voltage sampling circuit and a single-chip microcomputer minimum system, the single-chip microcomputer minimum system comprises a single-chip microcomputer and an LDO power supply, the equalization circuit comprises a plurality of modules, the plurality of modules are sequentially cascaded and connected, each module comprises a plurality of strings of cells, and the voltage sampling circuit is connected with the single-chip microcomputer. Each module simultaneously equalizes a plurality of strings of battery cells, the highest string of battery cells of the first module and the lowest string of battery cells of the second module are the same equalization unit and play roles in equalization transfer and cascade connection, and the odd modules and the even modules work alternately. The two ends of the module driving circuit and the voltage sampling circuit are ele
