1、蓄电池之小论蓄电池的作用及其原理蓄电池是一种化学电源,将化学能转变为电能,属于可逆直流电源.靠内部化学反应储存电能或向用电设备供电。汽车上使用蓄电池目的为了满足起动发动机需要,所以通常称为起动型蓄电池.蓄电池,必须满足用于汽车上的发动机需要,即在1~5s内的短时间内,提供汽车起动发动机足够大的电流。汽油机起动电流为200~600A,柴油机达1000A。目前燃油汽车上使用蓄电池根据电解液主要有两大类:铅酸蓄电池(以下简称铅蓄电池)和镍碱蓄电池。铅蓄电池一般由3个或6个单格电池串联而成,每个单格电池标称电压为2V,3格串联为6V。蓄电池的作用1)起
2、动发动机时,向起动系和点火系供电。2)当发动机低速运转,向用电设备供电。3)当发动机中、高速运转,将发电机的剩余电能储存起来。4)当发电机过载时,协助发电机向用电设备供电。5)蓄电池还吸收电路中的瞬时过电压,保持汽车电器系统电压的稳定,保护电子元件。蓄电池工作原理theirownconditionstodevelopthecorrectroad,themaximumtoavoidinvestmentrisk,gainprofit.(three)vigorouslypromotethebrand.Toestablishbrandawareness
