基于CTI-EKF融合算法高效节能二次电池化成系统设计
资料介绍
针对目前二次电池化成系统化成质量不高、节能效果不理想等缺点,提出了一种基于安时积分(Current Time Integration,CTI)和扩展卡尔曼滤波(Extend Kalman Filtering,EKF)融合算法的高效节能电池化成系统设计方案。系统采用STM32单片机为主控制器,运用改进卡尔曼滤波技术及PID算法,对电池SOC进行精准预测和充放电流电压的精确控制,同时采用高效AC/DC和DC/DC变换技术,有效提高电池化成质量和系统能量回收率。测试结果表明,采用PID算法电流控制误差不超过0.1%,系统相比目前带储能装置电池化成设备,其节能效率可以提高15.6%。
