電(dian)動(dong)車充電(dian)主要應把握兩個原則： 

    一是要淺(qian)放勤充(chong)。即應作到天天騎，天天充(chong)。因為(wei)電(dian)瓶(ping)放電(dian)的(de)(de)(de)過(guo)程就(jiu)是硫酸和鉛反應形成(cheng)硫酸鉛的(de)(de)(de)過(guo)程，充(chong)電(dian)的(de)(de)(de)過(guo)程就(jiu)是把硫酸鉛還原成(cheng)硫酸和鉛的(de)(de)(de)過(guo)程。

如果過度放電，硫(liu)酸(suan)鉛(qian)就不能還原，造成(cheng)極板的硫(liu)化(hua)。

    二是(shi)不(bu)能過充(chong)(chong)。充(chong)(chong)電時間過長(chang)會大(da)量消耗電瓶內的水分。如(ru)果長(chang)時間過充(chong)(chong)，會使電瓶因嚴重缺水而(er)容量漸漸下降(jiang)，直至充(chong)(chong)鼓、報廢。

    正確的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間為：綠燈(deng)亮(liang)了后再浮充(chong)(chong)(chong)(chong)2小(xiao)時(shi)，然后切(qie)斷電(dian)(dian)(dian)源(yuan)。可折算成騎車(che)(che)里程，以每(mei)天騎車(che)(che)40里計(ji)算，一般(ban)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)6―8小(xiao)時(shi)就足夠了。電(dian)(dian)(dian)動車(che)(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)都沒有過充(chong)(chong)(chong)(chong)保護功(gong)能(neng)(neng)，雖然綠燈(deng)亮(liang)了，但(dan)由于不能(neng)(neng)切(qie)斷電(dian)(dian)(dian)源(yuan)，其實電(dian)(dian)(dian)瓶仍在繼續充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，繼續消耗電(dian)(dian)(dian)瓶內的(de)水(shui)分，那種“充(chong)(chong)(chong)(chong)滿了就不充(chong)(chong)(chong)(chong)了”的(de)說法是完全沒有道理的(de)。 

     電(dian)動車(che)逐漸成為廣大(da)市民的主要交通工具，但(dan)由(you)于大(da)多數市民不懂得電(dian)瓶(ping)的充電(dian)放電(dian)原(yuan)理，不能(neng)按正確的方法(fa)充電(dian)，致使電(dian)瓶(ping)使用一年(nian)左右就報廢，造成資(zi)源和資(zi)金(jin)的巨大(da)浪費。教(jiao)你這兩招充電(dian)方法(fa)，必將(jiang)使你的電(dian)瓶(ping)壽命大(da)大(da)延長。
