2)充(chong)(chong)電(dian)(dian)(dian)時(shi)間長達6-8個小時(shi)，是比(bi)較(jiao)科學的(de)(de)(de)(de)。也就是說(shuo)，實際上電(dian)(dian)(dian)動汽(qi)車充(chong)(chong)電(dian)(dian)(dian)的(de)(de)(de)(de)便捷性是大家不(bu)能接受的(de)(de)(de)(de)。一是用家里220V交(jiao)流電(dian)(dian)(dian)來充(chong)(chong)電(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)時(shi)間要6-8小時(shi)；二是到充(chong)(chong)電(dian)(dian)(dian)站用直(zhi)流充(chong)(chong)電(dian)(dian)(dian)，除(chu)了排(pai)隊外(wai)，充(chong)(chong)電(dian)(dian)(dian)過程要的(de)(de)(de)(de)時(shi)間也必須(xu)要在30分鐘以(yi)上；三是買(mai)換電(dian)(dian)(dian)池的(de)(de)(de)(de)車吧，基本上沒有賣的(de)(de)(de)(de)。

二、提(ti)高充(chong)電方便性基本途徑
1)如(ru)果能用民用交(jiao)流電(dian)(dian)充(chong)電(dian)(dian)，如(ru)果充(chong)電(dian)(dian)時(shi)間少于要3小時(shi)能接受(shou)；
2)如果到充電站(zhan)用(yong)直(zhi)流充電，充電時間少(shao)于1個小時能接受；
3)如果換電(dian)池(chi)(chi)，必須電(dian)池(chi)(chi)是自己(ji)專(zhuan)用，是可(ke)以接受。
三(san)、鋰離子動力電(dian)池組的充電(dian)模式(shi)
下面是充電(dian)曲線，即充電(dian)模(mo)式采用“限(xian)流、限(xian)壓”兩階(jie)段充電(dian)模(mo)式。
1)限流(liu)過程(cheng)：
這一階段的充電叫“限(xian)流(liu)”充電，充電電流(liu)保(bao)持在限(xian)流(liu)值(zhi)。隨著充電的延續(xu)，電池電動勢不斷(duan)上升，電池的充電壓(ya)(ya)也不斷(duan)上升。當(dang)電池電壓(ya)(ya)上升到(dao)允許的最高充電電壓(ya)(ya)時，保(bao)持恒壓(ya)(ya)充電。廠家建議：一般采用最佳充電倍率(鋰離子電池為0.3CA)進(jin)行限(xian)流(liu)充電。
2)限壓(ya)過(guo)程：
在(zai)這(zhe)(zhe)一階段，由(you)于(yu)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)動勢(shi)(shi)還在(zai)不斷(duan)(duan)上(shang)升，而(er)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓又(you)保(bao)持不變(bian)，所以(yi)電(dian)(dian)(dian)池(chi)的(de)充(chong)電(dian)(dian)(dian)流呈(cheng)雙曲線趨勢(shi)(shi)不斷(duan)(duan)下(xia)降(jiang)，一直下(xia)降(jiang)到零。這(zhe)(zhe)一階段的(de)充(chong)電(dian)(dian)(dian)叫恒(heng)“恒(heng)壓”充(chong)電(dian)(dian)(dian)，這(zhe)(zhe)一階段的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓：U=E+IR=恒(heng)壓值。
(實際(ji)做(zuo)法(fa)：當充電電流(liu)減小到0.015CA時就可停(ting)止(zhi)充電。)
三(san)、對離子動力(li)電池組充電，實(shi)際是一(yi)個動態(tai)的過程(cheng)
充(chong)電系統必須具有(you)自動調節充(chong)電參數、自動控(kong)制和自動保護功(gong)能：
1)自動調(diao)節充(chong)電參數
a)例如，在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時，尤其在恒壓(ya)(ya)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)階段，如果電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組中有某(mou)一個單體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)超過允(yun)許(xu)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(根(gen)據不同鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)特性一般設定為3.9V～4.3V之間)時，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)系統應(ying)會根(gen)據電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)管理系統(BMS)輸出(chu)的(de)信號，自動(dong)減小充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，使該電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不超過允(yun)許(xu)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，防止該電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)過壓(ya)(ya)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。
b)再(zai)如，在充(chong)電(dian)開始時，經電(dian)池(chi)(chi)管理系(xi)統(BMS)監測到有某一個單體(ti)電(dian)池(chi)(chi)的(de)電(dian)壓過低，充(chong)電(dian)系(xi)統應能自動(dong)改小初始充(chong)電(dian)電(dian)流，待電(dian)池(chi)(chi)的(de)電(dian)壓正(zheng)常后，再(zai)轉入正(zheng)常充(chong)電(dian)。
所(suo)以，在充電(dian)(dian)過程中，充電(dian)(dian)系(xi)統必須(xu)能根據電(dian)(dian)池(chi)組的狀(zhuang)態(tai)、電(dian)(dian)池(chi)管理(li)系(xi)統(BMS)輸出(chu)的信息和整車監控輸出(chu)的信息，自(zi)動調節充電(dian)(dian)參數和自(zi)動控制充電(dian)(dian)。
2)自動控制和自動保(bao)護(hu)功能(neng)
在充(chong)電(dian)(dian)過(guo)程(cheng)中，電(dian)(dian)池(chi)組和電(dian)(dian)動車(che)發(fa)生任何不正常情況時(shi)，如電(dian)(dian)池(chi)組短路(lu)、斷(duan)路(lu)、高溫、起火和有電(dian)(dian)池(chi)損壞時(shi)，充(chong)電(dian)(dian)系(xi)統應能迅速(su)切斷(duan)電(dian)(dian)源(yuan)，停止充(chong)電(dian)(dian)。
3)與(yu)整(zheng)車CAN總線通(tong)信(xin)
在(zai)充電過程中(zhong)，充電系統(tong)的信息可與整車CAN總線(xian)通信。
