电动车蓄电池充电保护电路图,Lead-acid battery charger 这款保护电路既可以防止欠充电和过充电,还可以在充电器十小时不转换变灯的情况下自动断电,防止出现严重的错误。而且还可以用石英钟自动记下充电的时间。由此掌握蓄电池容量变化的情况,并判断是否出现了充电器不转换变绿灯的问题,以便决定要不要送维修点处理。 ...
铅酸电池无级调压充电电路,Lead-acid battery charger 关键字:铅酸电池充电器电路图 作者:李毛生 一、无级调压(流)充电器 在整流变压器初级串接一只市售风扇调速器(烤火箱调温器),调改输入工频电压就能达到无级调压的目的。输出波形虽不佳,实践证明是可行的。 充电时,只要充电电流调到符合要求,电压肯定也是合适...
摘要:简单的蓄电池充电保护电路 这里介绍一种+12V蓄电池充电时因过压的保护电路,如附图所示。图中的A、B端外接充电器电路(这里未绘出)对+12V电池进行充电。图中的Q1、D2、D1组成保护电路,其中D1(IN4743)为稳压管(+13.5V),D1和D2共同组成三极管Q1的偏置电路。R1是Q1管的限流电阻。 附图电路的A、B端是电...
可自动识别电池极性的蓄电池充电器--Lead-acid battery charger 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...
