電動車充(chong)電主要應把握兩個(ge)原則： 

    一(yi)是(shi)要淺放勤充(chong)。即應作到(dao)天(tian)(tian)天(tian)(tian)騎，天(tian)(tian)天(tian)(tian)充(chong)。因為(wei)電(dian)瓶放電(dian)的(de)(de)過(guo)程就(jiu)(jiu)是(shi)硫(liu)(liu)酸(suan)(suan)和鉛(qian)(qian)反應形成硫(liu)(liu)酸(suan)(suan)鉛(qian)(qian)的(de)(de)過(guo)程，充(chong)電(dian)的(de)(de)過(guo)程就(jiu)(jiu)是(shi)把硫(liu)(liu)酸(suan)(suan)鉛(qian)(qian)還原成硫(liu)(liu)酸(suan)(suan)和鉛(qian)(qian)的(de)(de)過(guo)程。

如果(guo)過度放電(dian)，硫酸(suan)鉛就不能還(huan)原，造成極板的(de)硫化。

    二是不能過充。充電(dian)(dian)時間過長(chang)會大量(liang)消(xiao)耗電(dian)(dian)瓶內的水(shui)分。如(ru)果長(chang)時間過充，會使電(dian)(dian)瓶因嚴重缺水(shui)而容(rong)量(liang)漸(jian)漸(jian)下降(jiang)，直(zhi)至充鼓、報廢。

    正(zheng)確的充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)為(wei)：綠(lv)燈亮了后(hou)再浮充(chong)(chong)2小時(shi)，然后(hou)切(qie)斷(duan)電(dian)(dian)(dian)源。可折算成騎車里程，以(yi)每天騎車40里計算，一般充(chong)(chong)電(dian)(dian)(dian)6―8小時(shi)就足(zu)夠了。電(dian)(dian)(dian)動車充(chong)(chong)電(dian)(dian)(dian)器都沒有過充(chong)(chong)保護功能，雖然綠(lv)燈亮了，但由于(yu)不能切(qie)斷(duan)電(dian)(dian)(dian)源，其實電(dian)(dian)(dian)瓶仍在繼續(xu)充(chong)(chong)電(dian)(dian)(dian)，繼續(xu)消耗電(dian)(dian)(dian)瓶內的水分，那種(zhong)“充(chong)(chong)滿了就不充(chong)(chong)了”的說法是(shi)完全沒有道理的。 

     電(dian)動車(che)逐漸(jian)成為廣(guang)大(da)市民的(de)(de)主要交(jiao)通工具，但(dan)由(you)于大(da)多數市民不(bu)懂(dong)得電(dian)瓶(ping)(ping)的(de)(de)充電(dian)放電(dian)原理(li)，不(bu)能按正確的(de)(de)方法(fa)充電(dian)，致使(shi)電(dian)瓶(ping)(ping)使(shi)用一年左右就報廢，造成資源和資金(jin)的(de)(de)巨大(da)浪費。教你這兩招(zhao)充電(dian)方法(fa)，必將使(shi)你的(de)(de)電(dian)瓶(ping)(ping)壽命(ming)大(da)大(da)延(yan)長。
