摘要
为了提升电池组的可靠性和寿命,基于改进型DC/DC斩波电路,提出了非合作博弈蚁群系统(NGACS)控制策略。分析其结构、工作原理和串联电池组模块化均衡方法,将蚁群系统结合非合作博弈进行改进,使其作为串联电池组均衡电路的控制系统。采用了PSIM仿真模型对电路及其控制策略进行分析,并进行试验验证。仿真和试验结果表明。均衡电路具有简单易实现、能量双向传输、均衡电流可控等特点,能够促进串联电池组的可靠运行和延长使用寿命。
In order to improve the reliability and life of thebattery pack,based on the improved DC-DC chopper circuit,acontrol strategy( NGACS) was proposed. Its structure,working principle and modular equalization method of serially connected battery packs were analyzed,the ant colony system is improved with non-cooperative game theory,which is used as the control system of serially connected battery packs equalization circuit. The PSIM simulation model was used to analyze the circuit and its control strategy,and a serially batteries was built for experimental verification. The simulation and experimental results show that this equalization circuit has the characteristics of easy realization,bidirectional energy transmission and control lable equalization current,which can promote the reliable operation of series connected battery packs and prolong their servicelife.
