电动车已经进入到每一个家庭,由于它个小灵活、出行方便深受大家喜爱,所以很多家庭已经达到每人一辆,在电动车给人们带来便利的同时,一些问题也就暴露了出来,不能跑远路,电池寿命短等问题,有很多朋友买新车不到一两年时间电瓶就不行了,因此大家想尽各种办法增大电瓶的容量,来延长它的使用时间,这个时候一些用户就会选择去加水修复电池,现在有些店家号称不用更换电池,花几十元钱就可解决电池弱电问题。那么,真相真的是这样么?今天就给大家分析一下。
首先,需要告诉大家的是,现在很多的电池都是免维护电池,其意味着这种电池是不需要加水的。这种电池如果出现续航下降的情况,一般是电池老化所引起。对于这类电池,只能选择换新,是无法加水修复的。
其次,我们来看下加水后的效果。一般来说,给电动车电池加水,根据测试在不充鼓的情况下,可以恢复电池60%的效果,但是这种状态只能保持短暂的几个月,甚至几个星期,根本就无法从根本上解决电池续航下降的问题。另外,需要说的一点是,如果加水量把握不准,还会直接损坏电池,导致电池报废。
最后,给大家介绍一下,到底什么情况下可以给电池加水?一般只适用于充电时红绿灯不跳灯的情况,而这种情况大多是由于电池缺水导致充不满,那就是告诉你不是充电器坏了就是电池缺水了。这种情况下电池需要加的也不是水而是电解液,而且加电解液的时候要把旧的电解液倒出来在加入新的,不然新的电解液加进去也没什么用了。值得注意的是电池在质保期内不要加。据有关资料表明,如果给不同的电池分别加入水(矿泉水)、蒸馏水、电解液,加水的电池报废率为90%,加蒸馏水的报废率是80%,加电解液的报废率为50%。
总之,电动车电池续航下降,无论加什么都不能从根本上修复电池,而且加多加少如果把握不准,甚至会直接损坏电池。对于用户来说,日常加强对电动车电池的保养,将在一定程度延长电池寿命,延长电动车续航能力。而不是等到电动车电池出现了问题,才想到去修复。
