提升阀控铅酸蓄电池内化成一次容检合格率的方法

A improved method for the first capacity check pass rate of valve-regulated lead-acid battery

为提升阀控铅酸蓄电池12 V 6 Ah内化成一次容检合格率,启动六西格玛改善绿带项目,通过漏斗工具、SMART原则、宏观流程图、价值流图、卡洛模型、卡方分析等,找出关键因子,并用DOE实验对关键因子进行验证。收集最优因子条件,将12 V 6 Ah内化成一次容检合格率由94.88%提升至99.5%以上。

In order to improve the primary capacity check pass rate of 12 V 6 Ah valve-regulated leadacid battery after container formation,Six Sigma Green Belt improvement project was started.The key factors were identified by funnel tool,SMART principle,macro flow chart,value flow map,Carlo model,and card square analysis,and the key factors were verified by DOE experiment.The optimal factor conditions were collected,and the pass rate of 12 V 6 Ah lead-acid battery was increased from 94.88%to over 99.5%.
