1、輸出電壓設定好后(hou)(例如36V)，若被充電(dian)(dian)(dian)瓶極板脫落斷開，造(zao)成某組電(dian)(dian)(dian)池不通，或出(chu)現短路，則電(dian)(dian)(dian)瓶端電(dian)(dian)(dian)壓即(ji)降低(di)或為零，這時充電(dian)(dian)(dian)器(qi)將(jiang)無輸(shu)出(chu)電(dian)(dian)(dian)流。 電動車快速充電站
2、若被充電(dian)瓶電(dian)壓(ya)偏離設定(ding)電(dian)壓(ya)，如設定(ding)電(dian)壓(ya)為36V，誤接24V、12V、6V電(dian)瓶等，充電(dian)器也無輸出電(dian)流，若設定為24V誤接(jie)為(wei)36V電(dian)瓶(ping)，由于充(chong)電(dian)器輸出(chu)電(dian)壓(ya)低于電(dian)瓶(ping)電(dian)壓(ya)，因而也不能向電(dian)瓶(ping)充(chong)電(dian)。
3、充電器兩(liang)輸出端若短路(lu)時(shi)，由于充電器中(zhong)可(ke)控(kong)硅SCR的觸發電路(lu)不能工作，因而可控硅不導通，輸(shu)出電流為零。
4、若(ruo)使用時誤將(jiang)電瓶正(zheng)負極接(jie)反，則可控硅觸發電路反向截止(zhi)，無觸發信號，可控硅不導通(tong)，輸出電流(liu)為零(ling)。
5、采用脈(mo)沖充電(dian)(dian)，有利(li)于(yu)延長(chang)電(dian)(dian)瓶壽(shou)命。由于(yu)低壓交(jiao)流(liu)電(dian)(dian)經全波整流(liu)后是(shi)脈(mo)動直流(liu)，只有當其波峰電(dian)(dian)壓大于(yu)電(dian)(dian)瓶電(dian)(dian)壓時，可(ke)(ke)控(kong)硅才會導(dao)通(tong)，而當脈(mo)動直流(liu)電(dian)(dian)壓處于(yu)波谷區(qu)時，可(ke)(ke)控(kong)硅反偏截止(zhi)，停止(zhi)向電(dian)(dian)瓶充電(dian)(dian)，因而流(liu)過電(dian)(dian)瓶的是(shi)脈(mo)動直流(liu)電(dian)(dian)。
6、快速充(chong)(chong)(chong)電，充(chong)(chong)(chong)滿自停(ting)。由于剛開(kai)始充(chong)(chong)(chong)電時電瓶(ping)兩端電壓較低，因而(er)充(chong)(chong)(chong)電電流較大。當(dang)電瓶(ping)即將充(chong)(chong)(chong)足時(36V電瓶端電壓可達(da)44V)，由于充(chong)電(dian)(dian)電(dian)(dian)壓越來(lai)越接近脈動(dong)直流(liu)輸出(chu)電(dian)(dian)壓的波峰值，則充(chong)電(dian)(dian)電(dian)(dian)流(liu)也會越來(lai)越小，自動(dong)變為(wei)涓流(liu)充(chong)電(dian)(dian)。當電(dian)(dian)瓶兩端電(dian)(dian)壓被充(chong)到整流(liu)輸出(chu)的波峰*大值時，充(chong)電(dian)(dian)過(guo)程停止。經試驗，三節電(dian)(dian)動(dong)車蓄電(dian)(dian)池36V(12V/12Ah三節串聯)，用該充(chong)(chong)電(dian)器(qi)只需幾個小(xiao)時即可(ke)充(chong)(chong)滿。
7、電路簡(jian)單、易于制作，幾(ji)乎不用維(wei)護(hu)及維(wei)修。
