电动客车配套电池的研制开发

介绍了为电动客车配套的阀控密封铅酸蓄电池的研制开发情况。采用含适当比例β-PbO的铅粉，并对α-PbO、β-PbO及游离Pb的比例加以控制；通过对和膏温度、固化湿度的严格控制，调节3 BS与4 BS的比例；采用多阶段极板化成工艺；通过更严格的公差控制保证产品的均匀性；主要部件包括槽、盖、隔板、极板、酸液密度及加入量等的精度均采取相应措施加以控制。电池检测结果，均匀性相对差值≤1％，耐过充性能良好。经48 h恒流过充后电池3 h容量较完全充电（16 h，14．4 V恒压充电）后电池3 h容量高出约5％～10％，密封反应效率均大于95％，荷电保持能力容量均在95％以上。

Study and development of lead-acid battery for electric bus

The study and development of lead-acid battery for electric bus were provided．The ratio of α-PbO，β-PbO and free Pb was controlled by using Pb powder with proper ratio of β-PbO； the ratio between 3 BS and 4 BS was regulated by strictly controlling mixing humidity and solidify humidity； multigrade plate formation technology was adopted； uniformity was protected by strictly controlling difference． The results show that the uniformity relative defference is less than 1％ and the battery has good overcharged performance． The battery capacity at overcharged constant current for 48 h is higher about 5％—10％ than complete charge， and sealed action ratio is more than 95％， charged capacity is more than 95％．
