摘　　要：适用于怠速、停行车用高性能阀控式铅蓄电池的开发是提高机动车燃油效率最简单的方法之一,随着人们对环保意识的加强,预计这种车型会普及推广。因此,已开始调研有关怠速、停行系统机动车在路面上运行的实况,并将高性能阀控式铅蓄电池与普通型铅蓄电池进行对比,发现这种高性能阀控式铅蓄电池在部分荷电状态运行时,其容量损失小于其它类型的铅蓄电池,因此它更适用于这种怠速停行车型。此外,历经3年试车运行试验后,其正板栅似乎呈现鳞片状腐蚀,不同于在起动、照明、点火的汽车电池板栅中通常所发现的那种腐蚀,且其腐蚀速度受正极板电位调整的抑制。Idling-stop（stop and go） system with lead-acid battery is a simple way to improve fuel economy of automobiles and is expected to spread widely from an environmenta ; perspective . Tjerefpre . the performance in rpad tests with an idling-stop vehicle has been investigated using advanced valve-regulated lead（VRLA） battery compared with the case of conventional one and flooded type batteries. The advanced battery was found out to be suited to idling-stop applications because it showed a smaller capacity loss than the other type of batteries during partial-state-of-charge（PSOC） operation. Furthermore, after the three-year road test, it appeared that the positive grid was corroded with lamellat structure since the corrosion proceeds mainly under PSOC conditions unlike the usually observed grain boundary corrosion of SLI battery grid. The corrosion rate was verified to be suppressed by potential control of positive plates.
