2)充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間長達(da)6-8個小(xiao)時(shi)，是(shi)比較科學的(de)。也就是(shi)說，實際上電(dian)(dian)(dian)(dian)(dian)動汽車充(chong)電(dian)(dian)(dian)(dian)(dian)的(de)便捷性是(shi)大家(jia)不(bu)能(neng)接(jie)受的(de)。一是(shi)用家(jia)里220V交流電(dian)(dian)(dian)(dian)(dian)來充(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間要6-8小(xiao)時(shi)；二是(shi)到充(chong)電(dian)(dian)(dian)(dian)(dian)站用直流充(chong)電(dian)(dian)(dian)(dian)(dian)，除了排隊(dui)外，充(chong)電(dian)(dian)(dian)(dian)(dian)過程(cheng)要的(de)時(shi)間也必(bi)須要在30分鐘以上；三是(shi)買換電(dian)(dian)(dian)(dian)(dian)池的(de)車吧，基本上沒有賣的(de)。

二(er)、提高充電方便性基(ji)本途徑
1)如果能(neng)(neng)用(yong)民用(yong)交流電(dian)充(chong)電(dian)，如果充(chong)電(dian)時(shi)間(jian)少于(yu)要3小時(shi)能(neng)(neng)接受(shou)；
2)如果到充(chong)(chong)電(dian)站用直流充(chong)(chong)電(dian)，充(chong)(chong)電(dian)時(shi)(shi)間少于(yu)1個小(xiao)時(shi)(shi)能接受(shou)；
3)如果(guo)換電(dian)池，必須電(dian)池是自己(ji)專用，是可以接受。
三、鋰離子動力電(dian)池組(zu)的充電(dian)模式(shi)
下面是充電(dian)曲線(xian)，即充電(dian)模(mo)式(shi)采用“限(xian)流、限(xian)壓”兩階段充電(dian)模(mo)式(shi)。
1)限流過(guo)程：
這一階段的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)叫“限流”充(chong)(chong)(chong)電(dian)(dian)(dian)，充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流保持在限流值。隨著充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)延續，電(dian)(dian)(dian)池電(dian)(dian)(dian)動勢不斷上升，電(dian)(dian)(dian)池的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)壓(ya)也不斷上升。當電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)上升到允(yun)許的(de)(de)最高(gao)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)時，保持恒壓(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)。廠家建議：一般采用最佳充(chong)(chong)(chong)電(dian)(dian)(dian)倍率(鋰(li)離子電(dian)(dian)(dian)池為0.3CA)進行(xing)限流充(chong)(chong)(chong)電(dian)(dian)(dian)。
2)限壓(ya)過程：
在這一階段(duan)，由(you)于電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)動(dong)勢還(huan)在不斷上升，而充電(dian)(dian)(dian)電(dian)(dian)(dian)壓又(you)保持不變(bian)，所以電(dian)(dian)(dian)池(chi)的充電(dian)(dian)(dian)流呈雙(shuang)曲線(xian)趨勢不斷下(xia)降，一直(zhi)下(xia)降到零。這一階段(duan)的充電(dian)(dian)(dian)叫(jiao)恒“恒壓”充電(dian)(dian)(dian)，這一階段(duan)的充電(dian)(dian)(dian)電(dian)(dian)(dian)壓：U=E+IR=恒壓值(zhi)。
(實際做法：當充電電流減小到0.015CA時就(jiu)可停止充電。)
三、對離子動(dong)力電池組充電，實(shi)際是一個動(dong)態的過(guo)程
充電(dian)(dian)系(xi)統必須具有自動(dong)調節充電(dian)(dian)參數、自動(dong)控制和自動(dong)保護功能(neng)：
1)自動調節充電參數
a)例如，在充電(dian)(dian)時(shi)(shi)，尤其(qi)在恒壓(ya)充電(dian)(dian)階(jie)段(duan)，如果電(dian)(dian)池(chi)(chi)組(zu)中有某一個單體(ti)電(dian)(dian)池(chi)(chi)的(de)(de)(de)充電(dian)(dian)電(dian)(dian)壓(ya)超過允許(xu)的(de)(de)(de)充電(dian)(dian)電(dian)(dian)壓(ya)(根據(ju)不(bu)同(tong)鋰電(dian)(dian)池(chi)(chi)的(de)(de)(de)特性一般設定為(wei)3.9V～4.3V之間)時(shi)(shi)，充電(dian)(dian)系統(tong)應會根據(ju)電(dian)(dian)池(chi)(chi)管理(li)系統(tong)(BMS)輸出的(de)(de)(de)信號(hao)，自動減小充電(dian)(dian)電(dian)(dian)壓(ya)和電(dian)(dian)流，使該電(dian)(dian)池(chi)(chi)的(de)(de)(de)充電(dian)(dian)電(dian)(dian)壓(ya)不(bu)超過允許(xu)的(de)(de)(de)充電(dian)(dian)電(dian)(dian)壓(ya)，防(fang)止該電(dian)(dian)池(chi)(chi)過壓(ya)充電(dian)(dian)。
b)再如(ru)，在充電(dian)(dian)開始時，經(jing)電(dian)(dian)池(chi)(chi)管理系統(BMS)監(jian)測到(dao)有某一個單體電(dian)(dian)池(chi)(chi)的電(dian)(dian)壓(ya)過低，充電(dian)(dian)系統應能自動改小初始充電(dian)(dian)電(dian)(dian)流，待電(dian)(dian)池(chi)(chi)的電(dian)(dian)壓(ya)正(zheng)常后，再轉(zhuan)入(ru)正(zheng)常充電(dian)(dian)。
所以，在充(chong)電(dian)過(guo)程中，充(chong)電(dian)系(xi)統(tong)(tong)必須(xu)能根據(ju)電(dian)池(chi)(chi)組的(de)狀態、電(dian)池(chi)(chi)管理系(xi)統(tong)(tong)(BMS)輸出(chu)的(de)信息(xi)和整車監(jian)控(kong)(kong)輸出(chu)的(de)信息(xi)，自動調節充(chong)電(dian)參(can)數和自動控(kong)(kong)制充(chong)電(dian)。
2)自動控制和自動保護功能(neng)
在充電(dian)過程中，電(dian)池組和(he)電(dian)動車發生任何(he)不正常情況時，如電(dian)池組短(duan)路、斷(duan)路、高溫、起火和(he)有電(dian)池損壞時，充電(dian)系(xi)統(tong)應能迅(xun)速切斷(duan)電(dian)源，停止充電(dian)。
3)與整車CAN總線(xian)通信
在充(chong)(chong)電過程中，充(chong)(chong)電系(xi)統(tong)的信息可(ke)與整車CAN總(zong)線通信。
