動(dong)力電(dian)池電(dian)源管理(li)系統也叫電(dian)池保護板目前存在問(wen)題及現狀：

當前動力鋰電池電(dian)源系統發(fa)展的主(zhu)要(yao)問題(ti)是(shi)：動(dong)(dong)(dong)(dong)力(li)電(dian)池(chi)成(cheng)組(zu)后安全性(xing)和(he)(he)使用(yong)(yong)壽命顯著下降(jiang)，甚至頻繁(fan)發(fa)生電(dian)池(chi)燃燒、爆炸等(deng)嚴重事故。造(zao)成(cheng)上述(shu)問題(ti)的主(zhu)要(yao)原因(yin)是(shi)動(dong)(dong)(dong)(dong)力(li)鋰電(dian)池(chi)成(cheng)組(zu)技術、成(cheng)組(zu)應用(yong)(yong)技術和(he)(he)設備研(yan)究滯后；實(shi)現動(dong)(dong)(dong)(dong)力(li)鋰電(dian)池(chi)系統集成(cheng)，為(wei)用(yong)(yong)戶提(ti)供(gong)動(dong)(dong)(dong)(dong)力(li)鋰電(dian)池(chi)系統集成(cheng)技術和(he)(he)產(chan)品(pin)，是(shi)解決當(dang)前面臨的問題(ti)，推動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)鋰電(dian)池(chi)發(fa)展的重要(yao)課題(ti)。

目前，單(dan)體(ti)(ti)動(dong)(dong)力(li)鋰電池已經基(ji)本具備(bei)推(tui)廣應用條件，但現有(you)的成(cheng)組技術(shu)、成(cheng)組應用技術(shu)和設(she)備(bei)水平還不成(cheng)熟。也就(jiu)是(shi)說(shuo)，單(dan)體(ti)(ti)動(dong)(dong)力(li)鋰電池基(ji)本解決了安全(quan)和壽命問(wen)題，推(tui)動(dong)(dong)動(dong)(dong)力(li)鋰電池發展的關鍵是(shi)電池成(cheng)組技術(shu)和BMS技術(shu)。

電源管理系統(tong)存在的必要性和重要性：

過(guo)(guo)(guo)充(chong)過(guo)(guo)(guo)放對(dui)(dui)電(dian)池(chi)(chi)(chi)的損害(hai)都是致(zhi)命(ming)的，不同(tong)之處(chu)僅(jin)在(zai)(zai)于過(guo)(guo)(guo)充(chong)產生大(da)量(liang)氣體(ti)、易(yi)自(zi)燃和爆炸(zha)、表象(xiang)劇烈，過(guo)(guo)(guo)放外觀變(bian)化和緩、但失效速度卻極快，在(zai)(zai)正常使(shi)用中(zhong)(zhong)都應嚴格避免出現。對(dui)(dui)于單體(ti)電(dian)池(chi)(chi)(chi)而(er)言，在(zai)(zai)充(chong)放電(dian)的過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)，如果過(guo)(guo)(guo)充(chong)或者(zhe)過(guo)(guo)(guo)放電(dian)都會造成(cheng)電(dian)池(chi)(chi)(chi)內阻增大(da)，負極析(xi)鋰，容量(liang)減小等一系列(lie)問題，使(shi)電(dian)池(chi)(chi)(chi)在(zai)(zai)使(shi)用過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)存在(zai)(zai)安全和壽命(ming)縮短的問題。對(dui)(dui)于電(dian)池(chi)(chi)(chi)組而(er)言，在(zai)(zai)成(cheng)組之前就需要單體(ti)電(dian)池(chi)(chi)(chi)的電(dian)性能(neng)基(ji)本一致(zhi)，在(zai)(zai)使(shi)用過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)也需要保持各個單體(ti)電(dian)池(chi)(chi)(chi)的性能(neng)一致(zhi)性，這樣電(dian)池(chi)(chi)(chi)才(cai)能(neng)盡量(liang)發(fa)揮1+1>1的效果。

電源(yuan)管理系統的構(gou)造：

電(dian)(dian)(dian)池(chi)管理(li)系統(tong)(tong)是對電(dian)(dian)(dian)池(chi)的(de)性能(neng)和(he)狀態了解最為全面的(de)設(she)備，所以將電(dian)(dian)(dian)池(chi)管理(li)系統(tong)(tong)和(he)充電(dian)(dian)(dian)機(ji)之(zhi)間建立(li)聯(lian)系，就(jiu)能(neng)使充電(dian)(dian)(dian)機(ji)實(shi)時地了解電(dian)(dian)(dian)池(chi)的(de)信(xin)息(xi)，從而更有(you)效地解決電(dian)(dian)(dian)池(chi)的(de)充電(dian)(dian)(dian)時產生一(yi)些(xie)的(de)問題。目前電(dian)(dian)(dian)池(chi)管理(li)系統(tong)(tong)都是基于單(dan)體電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)流(liu)、溫(wen)度等SOC狀態的(de)。

電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)管(guan)理系(xi)統(tong)對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)的(de)使(shi)用過程(cheng)進行管(guan)理，對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)中各單體(ti)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)狀(zhuang)(zhuang)態(tai)(tai)進行調整，可以在一定程(cheng)度上維系(xi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)中各單體(ti)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)狀(zhuang)(zhuang)態(tai)(tai)一致性，避免電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)狀(zhuang)(zhuang)態(tai)(tai)差異造(zao)成電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)性能的(de)加速衰(shuai)退。動(dong)力鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)發展需要電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)生產工藝控制水平的(de)提(ti)高，科學的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)篩選(xuan)和配組(zu)方法(fa)及(ji)有效的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)管(guan)理系(xi)統(tong)共同推動(dong)。

BSMS不(bu)僅可實時(shi)(shi)跟蹤采(cai)集數據(ju)記(ji)錄，更能對充放電進行實時(shi)(shi)控制。
