锂动力电池化成能量回馈控制系统的研究

摘要

An all-digital formation energy feedback control System besed on a new type of soecial digital signal controller TMS320F28035 for large capacity lithium power battery that has excellent application prospect was proposed to solve the energy waste problem existing in the process of battery formation, Employing an advanced main power topology structure and double-loop single-cycle control algorithm using feedback plus feed-forward, the system can successfully achieve the constant current, constant voltage cherging and discharging process of lithium bakery and efficient energy feedback.%针对目前锂动力电池良好的应用前景和电池化成过程中存在大量的能源浪费问题,提出了一种采用新型专用数字信号控制器(DSC)TMS320F28035的全数字大容量锂动力电池化成能量回馈控制系统.该系统采用一种先进的主电源拓扑结构,运用反馈+前馈的双闭环单周控制算法,能够实现锂电池的恒流、恒压充放电过程及化成能量的高效回馈.
