摘要
通过阀控铅酸电池不同程度深放电的实验 ,研究了深放电对电池初期容量、荷电保持率、深循环寿命等性能的影响 ,并对影响性能的原因作了分析。研究表明 :由于电池深放电后进行再充电 ,α PbO2 与 β PbO2 相对含量的改变 ,从而引起了深放电后电池性能的改变。电池经过深放电有利于提高电池的初期容量但大大地缩短了电池的深循环寿命。
The influence of over deep discharging on property including initial capacity,charge retention and deep cycle life of battery was investigated through valve regulated lead acid battery over deep discharging in different degree. And the reason affecting property of battery was analyzed too. It was showed that: The property of changing battery was resulted from the relative content of α PbO 2 and β PbO 2 changing during recharging after battery deep discharging. The initial capacity of battery was increased, and the deep cycle life was shortened greatly because of over deep discharging.
