摘要:可自动识别电池极性的蓄电池充电器作者:张文新 现在市面上销售的蓄电池充电器品种繁多,但是保护功能大多都是靠保险管的熔断提供过流保护,并且使用时还要区别正负极。如果使用者把充电器和蓄电池的极性接反是非常危险的事情。轻则烧断保险管。重则烧毁变压器和整流桥。 笔者设计了一个自动识别蓄电池极性。 且...
铅蓄电池过充、过放保护电路,Lead-acid battery over charge, over discharge protection circuit 关键字:铅蓄电池过充、过放保护电路 铅蓄电池过充、过放保护电路 市售应急灯都带有过充保护功能,但往往没有放电保护。铅蓄电池如果放电过度,将使硫酸铅晶体结成较大的体,这不仅增加了极板的电阻,而且在充电时很难...
