摘要
目前人们所熟知的备用电源用途阀控式铅酸蓄电池有两种技术,胶体电解质技术和AGM系统。两种系统与普通电池的区别在于使用了固态化的电解液,实现了氧的再化合。胶体式蓄电池比AGM结构电池的再化合速度低,因而其浮充电流小,产生的热量也比AGM的电池少许多。由于胶体电池的浮充电流小,还没有观察到在浮充条件下由于过热而导致热失控现象。讨论了工业用胶体蓄电池的气体释出和浮充寿命。用户十分希望不通过放电来辨别阀控式电池的健康状态,但到目前为止还未能实现。
Valve regulated batteries for stand by application are knowntoday in two technologies, the gel and AGM-system- Hoth systems distiguish from conventional batteries by using solidified electrolyte to enahle theoxygen recombination. Because gel batteries have a lower recomhinationrate than AGM-type, float current and heat generat lon of gel cells are lower than those for AGM-cells too.Aceording to the low float current, overheating up to thertnal runaway isnot noticed at gel batteries in float applications. Properties of industrial gelbatteries in gas evolution and float life are discussed.A strong demand from the user is the possibility to recognize the state ofhealth of valve regulated batteries without discharging, which could not besolved up today.
