當前動力鋰電池電源系統(tong)(tong)發(fa)(fa)展的主(zhu)要問題(ti)是(shi)：動(dong)(dong)力電池(chi)成(cheng)組(zu)后安全性和(he)使用(yong)壽命顯(xian)著下(xia)降，甚至頻繁發(fa)(fa)生電池(chi)燃燒、爆(bao)炸等嚴重事故。造成(cheng)上述問題(ti)的主(zhu)要原因(yin)是(shi)動(dong)(dong)力鋰(li)電池(chi)成(cheng)組(zu)技(ji)(ji)術、成(cheng)組(zu)應用(yong)技(ji)(ji)術和(he)設備研(yan)究滯后；實現動(dong)(dong)力鋰(li)電池(chi)系統(tong)(tong)集成(cheng)，為用(yong)戶提(ti)供動(dong)(dong)力鋰(li)電池(chi)系統(tong)(tong)集成(cheng)技(ji)(ji)術和(he)產品，是(shi)解決當前面臨(lin)的問題(ti)，推動(dong)(dong)動(dong)(dong)力鋰(li)電池(chi)發(fa)(fa)展的重要課題(ti)。

目前，單體動力鋰電池已經基本具備(bei)推廣應(ying)用條件，但現有的成(cheng)組技術、成(cheng)組應(ying)用技術和(he)設備(bei)水平還不(bu)成(cheng)熟(shu)。也就(jiu)是(shi)說(shuo)，單體動(dong)力鋰(li)電(dian)池基本解決(jue)了安全和(he)壽命問題，推動(dong)動(dong)力鋰(li)電(dian)池發展的關鍵是(shi)電(dian)池成(cheng)組技術和(he)BMS技術。

電源管理系統(tong)存(cun)在的(de)必(bi)要性和重要性：

過(guo)(guo)(guo)(guo)充(chong)過(guo)(guo)(guo)(guo)放(fang)對電(dian)池的損害都(dou)是(shi)致(zhi)命(ming)的，不同之(zhi)處(chu)僅在(zai)于(yu)(yu)過(guo)(guo)(guo)(guo)充(chong)產生大量氣體(ti)、易(yi)自燃(ran)和爆炸、表象劇烈(lie)，過(guo)(guo)(guo)(guo)放(fang)外觀(guan)變化和緩(huan)、但失效速度卻極快，在(zai)正常使用中(zhong)都(dou)應嚴格避免出現。對于(yu)(yu)單體(ti)電(dian)池而言，在(zai)充(chong)放(fang)電(dian)的過(guo)(guo)(guo)(guo)程(cheng)中(zhong)，如果(guo)過(guo)(guo)(guo)(guo)充(chong)或(huo)者過(guo)(guo)(guo)(guo)放(fang)電(dian)都(dou)會(hui)造成(cheng)電(dian)池內阻增大，負極析鋰，容量減小等一系列問(wen)(wen)題，使電(dian)池在(zai)使用過(guo)(guo)(guo)(guo)程(cheng)中(zhong)存在(zai)安全(quan)和壽命(ming)縮短的問(wen)(wen)題。對于(yu)(yu)電(dian)池組而言，在(zai)成(cheng)組之(zhi)前就需要(yao)單體(ti)電(dian)池的電(dian)性能基本一致(zhi)，在(zai)使用過(guo)(guo)(guo)(guo)程(cheng)中(zhong)也需要(yao)保持各個單體(ti)電(dian)池的性能一致(zhi)性，這樣(yang)電(dian)池才能盡量發(fa)揮1+1>1的效果(guo)。

電(dian)源管理系(xi)統的構造：

電(dian)(dian)(dian)(dian)池(chi)管理系統是對(dui)電(dian)(dian)(dian)(dian)池(chi)的(de)性能和狀(zhuang)態了解(jie)(jie)(jie)最為(wei)全面的(de)設備，所以將電(dian)(dian)(dian)(dian)池(chi)管理系統和充(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)之間(jian)建立聯系，就能使充(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)實時(shi)地了解(jie)(jie)(jie)電(dian)(dian)(dian)(dian)池(chi)的(de)信息，從而更有效地解(jie)(jie)(jie)決(jue)電(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)電(dian)(dian)(dian)(dian)時(shi)產生一些的(de)問題。目(mu)前電(dian)(dian)(dian)(dian)池(chi)管理系統都是基于單體(ti)電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)流、溫度等SOC狀(zhuang)態的(de)。

電(dian)(dian)池(chi)(chi)(chi)管理系統對電(dian)(dian)池(chi)(chi)(chi)組的(de)(de)(de)(de)使用(yong)過程(cheng)進行(xing)管理，對電(dian)(dian)池(chi)(chi)(chi)組中各單(dan)體電(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)狀態(tai)進行(xing)調整，可以在一定(ding)程(cheng)度上維系電(dian)(dian)池(chi)(chi)(chi)組中各單(dan)體電(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)狀態(tai)一致性，避免電(dian)(dian)池(chi)(chi)(chi)狀態(tai)差(cha)異造成(cheng)電(dian)(dian)池(chi)(chi)(chi)組性能的(de)(de)(de)(de)加速(su)衰退。動(dong)力鋰電(dian)(dian)池(chi)(chi)(chi)發展(zhan)需要(yao)電(dian)(dian)池(chi)(chi)(chi)生產工藝控制水平的(de)(de)(de)(de)提高，科學的(de)(de)(de)(de)電(dian)(dian)池(chi)(chi)(chi)篩選和配組方法及有效的(de)(de)(de)(de)電(dian)(dian)池(chi)(chi)(chi)管理系統共同(tong)推動(dong)。

BSMS不(bu)僅可實時(shi)跟蹤采集數據記錄，更能對充放電進(jin)行實時(shi)控制。
