柴油发电机组使用常见问题（蓄电池的性能） Common problems in using diesel generator sets (battery performance)

柴油发电机组蓄电池的性能和容量试验

柴油发电机电池劣化到定额容量的80%时必须换掉，也就是说如果一个电池系统新的时候能供电100安培一个小时，到后来同样一个小时只能供电80安培便必须换掉了如果100安培是实际负载而且必须供电至少一个小时，那么电池新的时候必须是原设计能供电125安培一个小时的在原先设计电池时这个1.25的因子就称为老化因子。电池容量降到定额的80%是指极板格栅已经腐蚀和膨胀，极板活性材料已经劣化，电解液已经开始干涸此时，电池容量下降，就该退出服务。

当然，电池调换还有其他原因，譬如，不再支持负载最小的要求时间即使电池仍有大于80%的定额还有，电池到达定额的80%这一点时，即使是最小的负载，电池也不应继续工作。

电池各项数据是在77°F（25°C）的值重要的是要知道在较低温度下操作当然不会损坏电池，但工作时间会减少，随温度降低的性能下降。在较高温度下连续工作会使电池加速老化，比77°F（25°C）每高出18°F（10°C）电池老化就会比正常快一倍。

Performance and Capacity Test of Diesel Generator Battery

When the diesel generator battery deteriorates to 80% of its rated capacity, it must be replaced. This means that if a new battery system can supply 100 amperes per hour, but can only supply 80 amperes per hour, it must be replaced. If 100 amperes is the actual load and must be supplied for at least one hour, then the new battery must be designed to supply 125 amperes per hour. This 1.25 factor is called the aging factor when the original battery was designed. When the battery capacity drops to 80% of the quota, it means that the plate grid has corroded and expanded, the active material of the plate has deteriorated, and the electrolyte has started to dry up. At this point, the battery capacity decreases and it should be taken out of service.

Of course, there are other reasons for battery swapping, such as no longer supporting the minimum load requirement time, even if the battery still has more than 80% of the quota. When the battery reaches 80% of the quota, even with the minimum load, the battery should not continue to work.

The various data of the battery are at a value of 77 ° F (25 ° C). It is important to know that operating at lower temperatures will not damage the battery, but the working time will be reduced and the performance will decrease with decreasing temperature. Continuous operation at higher temperatures will accelerate battery aging, with battery aging occurring twice as fast as normal for every 18 ° F (10 ° C) increase above 77 ° F (25 ° C).
