1、電動車應怎樣正確充(chong)電？

主要應把握兩個原(yuan)則：一是要淺放勤充(chong)。二是不能過(guo)充(chong)。注意(yi)電(dian)瓶車禁止虧電(dian)存放，會(hui)嚴重(zhong)影響使用(yong)壽(shou)命，如果閑置時間越長，蓄電(dian)池(chi)損壞也越嚴重(zhong)。

2、為什么要淺放勤充？

電(dian)(dian)(dian)瓶(ping)放電(dian)(dian)(dian)時形成(cheng)硫(liu)酸鉛，充電(dian)(dian)(dian)時把(ba)硫(liu)酸鉛還(huan)(huan)原成(cheng)硫(liu)酸和鉛。如果(guo)深(shen)度(du)放電(dian)(dian)(dian)或不及時充電(dian)(dian)(dian)，硫(liu)酸鉛就不能還(huan)(huan)原，造成(cheng)極板的硫(liu)化。所(suo)以，應作到天(tian)天(tian)騎(qi)，天(tian)天(tian)充，不可深(shen)度(du)放電(dian)(dian)(dian)。

3、充電時間不能過長有什么危(wei)害？

充(chong)電(dian)時(shi)間過長(chang)會(hui)過量(liang)消耗電(dian)瓶(ping)內(nei)的水(shui)分，加速極(ji)板(ban)的硫化過程，使電(dian)瓶(ping)因(yin)缺水(shui)而(er)容量(liang)漸漸下降，直至把電(dian)瓶(ping)充(chong)鼓、報廢。

4、怎(zen)樣把握(wo)正確的充(chong)電時間？

正確的充(chong)(chong)電(dian)(dian)(dian)時間為(wei)；綠(lv)燈亮了(le)后再浮充(chong)(chong)1—2小時，然后切斷電(dian)(dian)(dian)源。電(dian)(dian)(dian)動車充(chong)(chong)電(dian)(dian)(dian)器都沒(mei)(mei)有(you)過充(chong)(chong)保護功能，雖然綠(lv)燈亮了(le)，但由于不能切斷電(dian)(dian)(dian)源，其(qi)實電(dian)(dian)(dian)瓶仍(reng)在繼續(xu)充(chong)(chong)電(dian)(dian)(dian)，繼續(xu)分(fen)解、蒸發電(dian)(dian)(dian)瓶內的水分(fen)。那種(zhong)“充(chong)(chong)滿了(le)就(jiu)不充(chong)(chong)了(le)”的說法是(shi)完全沒(mei)(mei)有(you)科學道理的。

5、造(zao)成電瓶(ping)短命的主(zhu)要(yao)原因是什么？

充電不及時和充電時間(jian)過(guo)長是(shi)造(zao)成(cheng)電瓶短命的主(zhu)要原(yuan)因。
