摘要
浮充电压选择对阀控密封铅蓄电池组的使用寿命影响很大:浮充电压选得太高,会导致电池失水、热失控、均匀性恶化;浮充电压选得太低,会使电池充电不足,充电时间延长,极板硫酸盐化。由浮充电压均匀性和浮充电流变化,可以在线评估阀控密封铅蓄电池组的健康状况和使用寿命。
It has important influence to the service life of VRLA group that how to select the floating voltage. If the value was selected higher, batteries would lose more water and be out of control to heat, the uniformity of which would be worse also; if the value lower, LRLA group would be charged insufficiently, the charging time be longer and the plates of battery be sulfated. Based on the change for the uniformity of floating voltage and the value of floating current, it would be possible to evaluate the state of health and service life of VRLA group.
