基于电感储能的新型锂电池组多模式均衡电路OA

To address the issues of high diode conduction loss and limited equalization paths in exist-ing inductor-based battery equalization circuits,a novel multi-mode equalization topology was pro-posed based on the concept of reconfigurable circuits.This circuit reduced conduction loss in the equalization loop by reusing switching transistors to replace diodes.Furthermore,by optimizing the switch array structure and introducing a dynamic grouping strategy,it enabled flexible energy trans-fer between any number of battery cells.The paper elaborated on the topology structure,operational principles,and key parameter design,and proposed a state of charge(SOC)-based grouping strategy alongside a switch conduction strategy.Experimental validation was conducted using a series-connected pack of six lithium-ion batteries under static,charging,and discharging conditions.The re-sults demonstrate that the proposed circuit achieves an equalization efficiency of 75.37%under static conditions,which is approximately 21.16%higher than conventional schemes.Additionally,the equal-ization time was reduced by an average of over 20%across test conditions,verifying the proposed to-pology's advantages in both efficiency and flexibility.
