1、故障现象
①首先检查回路连接是否接触完好,认真检查插座和插头是否有“打火”烧弧现象,有无线路损伤断线等。
②检查充电器有无损坏,充电参数是否符合要求:即初期充电电流达到1.6-2.5A/只;最高充电电压达到14.8-14.9V/只,充电浮充电转换电流达0.3-0.4A/只,浮充电压达到14.0-14.4V/只。
③查看电池内部是否有干涸现象,即电池是否缺液严重。
④还应检查极板是否存在硫化。极板的不可逆硫酸盐化,可通过QN--1000初步判断(一般放电检测在6V以下)然后用容量检测仪测试,放电时间达不到规定容量50%的一般是出现不可逆硫酸盐化。另外,在充电时,电池的电压上升特别快,某些单格电压特别高,超出正常值很多;放电时电压下降特别快,电池不存电或存电很少。出现上述情况,可判断电池出现不可逆硫酸盐化。
2、故障的检查和处理
将电路各部位连接牢固,充电器不正常的必须进行更换。电池格内干涸的应补加纯水进行脉冲修复。
应控制配组的三只电池的电压均在13.4V/只以上为好。如果电池之间电压差别超过0.3V,就会出现因为不同步而在使用过程中继续产生硫化。所以要特别注意修复后电池的配组问题(特别是电摩电池的用户)需要更换的就必须更换。

充电器充电时内部是直接用线接电瓶的,如果充电器是好的话,电瓶有问题啦

回答3:

可能是你的充电器坏了,你可以用别的充电器试一下,如果能正常 就是充电器坏了。还有一种可能就是电瓶确实坏掉了,可以去修理铺做一下放电试验。看看缺不缺水。

回答4:

插充电器显绿灯,此时打开电源锁,充电器变亮红灯且整车有电。拔掉充电器(电源锁ON或者OFF),车子没电。是因为充电器直接给控制器供电。
解决方法:检查电瓶盒内电线是否脱焊。检查电瓶至控制器电源是否有电(有电正常)。

回答5:

你可以拆开一下电池盒,电池应该是快变形了,电池里已经没有液体了.如果变了形就没得救了,没有变形赶快去补液,这样还可以维持一段时间.你骑了40多分钟是因为现在是天热,如果是冬天你可能只能骑十多分钟了.
还有一种可能,如果你的电动车在很多时间里没有充电的话,(10天以上)电池严重亏电,会导至电池充不进电,如果这样的话,你要到专业店里把电池单个的充电.如你所述,这种可能不会出现.应该是换电池的时候了.呵呵,现在电池可不便宜啊.
