摘要
動力電池和儲能電池之間有什么區別和聯系
由于應用場景不同,電池的性能要求也有所不同。絕大多數儲能裝置無需移動,因此儲能鋰電池對于能量密度并沒有直接的要求。相對于動

  動力電池和儲能電池之間有什(shen)么區別和聯系

  由于(yu)應(ying)用(yong)(yong)(yong)場景不(bu)同,電(dian)(dian)池(chi)(chi)的(de)性能(neng)(neng)(neng)要求也有(you)所不(bu)同。絕(jue)大多數儲(chu)能(neng)(neng)(neng)裝置無需(xu)移動(dong),因(yin)此儲(chu)能(neng)(neng)(neng)鋰電(dian)(dian)池(chi)(chi)對(dui)于(yu)能(neng)(neng)(neng)量密(mi)度并沒有(you)直接的(de)要求。相(xiang)對(dui)于(yu)動(dong)力鋰電(dian)(dian)池(chi)(chi)而(er)言,儲(chu)能(neng)(neng)(neng)鋰電(dian)(dian)池(chi)(chi)對(dui)于(yu)使用(yong)(yong)(yong)壽命有(you)更高(gao)的(de)要求。在(zai)成(cheng)本(ben)方面,動(dong)力鋰電(dian)(dian)池(chi)(chi)面臨和傳統燃(ran)油動(dong)力源的(de)競爭,儲(chu)能(neng)(neng)(neng)鋰電(dian)(dian)池(chi)(chi)則需(xu)要面對(dui)傳統調峰調頻技(ji)術的(de)成(cheng)本(ben)競爭。電(dian)(dian)池(chi)(chi)是(shi)用(yong)(yong)(yong)來儲(chu)存電(dian)(dian)量的(de),從應(ying)用(yong)(yong)(yong)上來講,都(dou)(dou)是(shi)儲(chu)能(neng)(neng)(neng)的(de),因(yin)此可以說所有(you)的(de)鋰電(dian)(dian)池(chi)(chi)都(dou)(dou)是(shi)儲(chu)能(neng)(neng)(neng)電(dian)(dian)池(chi)(chi),后來為了區分應(ying)用(yong)(yong)(yong),按(an)場景分為消費電(dian)(dian)池(chi)(chi)、動(dong)力電(dian)(dian)池(chi)(chi)和儲(chu)能(neng)(neng)(neng)電(dian)(dian)池(chi)(chi)三種。消費類(lei)應(ying)用(yong)(yong)(yong)是(shi)在(zai)手機、筆(bi)記本(ben)電(dian)(dian)腦、數碼相(xiang)機等消費類(lei)產(chan)品,動(dong)力類(lei)應(ying)用(yong)(yong)(yong)在(zai)電(dian)(dian)動(dong)汽車上,儲(chu)能(neng)(neng)(neng)類(lei)應(ying)用(yong)(yong)(yong)在(zai)儲(chu)能(neng)(neng)(neng)電(dian)(dian)站上。

  電(dian)(dian)池是用來儲(chu)存電(dian)(dian)量的,從應(ying)用上(shang)來講(jiang),都(dou)是儲(chu)能(neng)(neng)(neng)的,因此可以(yi)說(shuo)所有的鋰電(dian)(dian)池都(dou)是儲(chu)能(neng)(neng)(neng)電(dian)(dian)池,后來為了(le)區分應(ying)用,按場景(jing)分為消(xiao)費電(dian)(dian)池、動(dong)(dong)力(li)電(dian)(dian)池和(he)儲(chu)能(neng)(neng)(neng)電(dian)(dian)池三種。消(xiao)費類(lei)(lei)應(ying)用是在(zai)手機、筆記本電(dian)(dian)腦、數碼相機等消(xiao)費類(lei)(lei)產(chan)品,動(dong)(dong)力(li)類(lei)(lei)應(ying)用在(zai)電(dian)(dian)動(dong)(dong)汽車上(shang),儲(chu)能(neng)(neng)(neng)類(lei)(lei)應(ying)用在(zai)儲(chu)能(neng)(neng)(neng)電(dian)(dian)站上(shang)。

  動(dong)力(li)電(dian)(dian)(dian)池(chi)其實(shi)也是儲能(neng)電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)一種(zhong),主(zhu)要(yao)應用于(yu)(yu)電(dian)(dian)(dian)動(dong)汽(qi)車,由于(yu)(yu)受(shou)到汽(qi)車的(de)(de)(de)(de)體積和重(zhong)量限制以(yi)及啟(qi)動(dong)加(jia)速(su)等(deng)要(yao)求(qiu),動(dong)力(li)電(dian)(dian)(dian)池(chi)比普通的(de)(de)(de)(de)儲能(neng)電(dian)(dian)(dian)池(chi)有(you)更高的(de)(de)(de)(de)性能(neng)要(yao)求(qiu),如(ru)能(neng)量密度要(yao)盡量高,電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)充(chong)電(dian)(dian)(dian)速(su)度要(yao)快,放電(dian)(dian)(dian)電(dian)(dian)(dian)流要(yao)大,但普通儲能(neng)電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)要(yao)求(qiu)沒(mei)有(you)這么高,根據標準,動(dong)力(li)電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)容量低于(yu)(yu)80%就不能(neng)再用在(zai)新能(neng)源汽(qi)車了,但稍加(jia)改造,還可(ke)以(yi)用在(zai)儲能(neng)系統中。

  從應用場(chang)景來看,動(dong)力(li)鋰(li)電(dian)池(chi)主要用于電(dian)動(dong)汽(qi)車、電(dian)動(dong)自行車以及(ji)其它電(dian)動(dong)工具領(ling)域,而儲能鋰(li)電(dian)池(chi)主要用于調峰調頻電(dian)力(li)輔助服(fu)務、可再生能源并網和(he)微電(dian)網等(deng)領(ling)域。

  由于(yu)(yu)應(ying)用(yong)(yong)場景(jing)不(bu)同,電(dian)(dian)(dian)池(chi)的(de)(de)性(xing)能(neng)(neng)要求(qiu)(qiu)也(ye)有所不(bu)同。首先(xian),動力(li)鋰電(dian)(dian)(dian)池(chi)作(zuo)為(wei)(wei)移動電(dian)(dian)(dian)源,在安(an)全的(de)(de)前(qian)提下對于(yu)(yu)體積(ji)(和質量(liang)(liang))能(neng)(neng)量(liang)(liang)密度盡可能(neng)(neng)有高(gao)的(de)(de)要求(qiu)(qiu),以達到更(geng)為(wei)(wei)持久的(de)(de)續航能(neng)(neng)力(li)。同時(shi),用(yong)(yong)戶還希(xi)望(wang)電(dian)(dian)(dian)動汽車能(neng)(neng)夠安(an)全快(kuai)充,因此(ci)動力(li)鋰電(dian)(dian)(dian)池(chi)對于(yu)(yu)能(neng)(neng)量(liang)(liang)密度和功率(lv)密度都(dou)有較高(gao)的(de)(de)要求(qiu)(qiu),只是(shi)因為(wei)(wei)出于(yu)(yu)安(an)全性(xing)考慮,目前(qian)普遍采用(yong)(yong)1C左右(you)充放電(dian)(dian)(dian)能(neng)(neng)力(li)的(de)(de)能(neng)(neng)量(liang)(liang)型電(dian)(dian)(dian)池(chi)。

  絕(jue)大多數(shu)儲能(neng)裝置無需(xu)移動,因(yin)此儲能(neng)鋰(li)電池對于能(neng)量密度(du)并沒(mei)有(you)直接的(de)要求(qiu)。至于功率密度(du),不(bu)同的(de)儲能(neng)場景有(you)不(bu)同的(de)要求(qiu)。

  用(yong)于電(dian)(dian)力(li)調峰、離網(wang)型(xing)光(guang)伏儲(chu)能(neng)或(huo)用(yong)戶側(ce)的(de)峰谷價差(cha)儲(chu)能(neng)場景(jing),一(yi)般(ban)需(xu)要(yao)(yao)儲(chu)能(neng)電(dian)(dian)池連(lian)續(xu)充電(dian)(dian)或(huo)連(lian)續(xu)放電(dian)(dian)兩個小時以(yi)上,因此適合(he)采用(yong)充放電(dian)(dian)倍率≤0.5C的(de)容量型(xing)電(dian)(dian)池;對于電(dian)(dian)力(li)調頻(pin)或(huo)平滑可再生能(neng)源(yuan)波動的(de)儲(chu)能(neng)場景(jing),需(xu)要(yao)(yao)儲(chu)能(neng)電(dian)(dian)池在秒級至分鐘級的(de)時間段快速充放電(dian)(dian),所以(yi)適合(he)≥2C功率型(xing)電(dian)(dian)池的(de)應用(yong);而在一(yi)些同時需(xu)要(yao)(yao)承(cheng)擔調頻(pin)和調峰的(de)應用(yong)場景(jing),能(neng)量型(xing)電(dian)(dian)池會(hui)更(geng)適合(he)些,當然,這(zhe)種場景(jing)下也可以(yi)將功率型(xing)與容量型(xing)電(dian)(dian)池配合(he)一(yi)起使用(yong)。

  相對(dui)于(yu)動力鋰電池(chi)而(er)言(yan),儲(chu)能(neng)鋰電池(chi)對(dui)于(yu)使用(yong)壽(shou)命(ming)有更高的(de)(de)(de)要求。新能(neng)源(yuan)汽車的(de)(de)(de)壽(shou)命(ming)一(yi)般在5-8年,而(er)儲(chu)能(neng)項目的(de)(de)(de)壽(shou)命(ming)一(yi)般都希望大于(yu)10年。動力鋰電池(chi)的(de)(de)(de)循(xun)環(huan)次數壽(shou)命(ming)在1000-2000次,而(er)儲(chu)能(neng)鋰電池(chi)的(de)(de)(de)循(xun)環(huan)次數壽(shou)命(ming)一(yi)般要求能(neng)夠大于(yu)3500次。

  在成本(ben)(ben)方(fang)面,動力(li)(li)鋰電(dian)池面臨和(he)傳統燃油(you)動力(li)(li)源(yuan)的(de)競爭(zheng),儲(chu)能鋰電(dian)池則需要(yao)面對傳統調峰調頻技術的(de)成本(ben)(ben)競爭(zheng)。另(ling)外,儲(chu)能電(dian)站的(de)規模基本(ben)(ben)上都是兆(zhao)瓦(wa)級別以上甚至百兆(zhao)瓦(wa)的(de)級別,因此儲(chu)能鋰電(dian)池的(de)成本(ben)(ben)要(yao)求(qiu)比動力(li)(li)鋰電(dian)池的(de)成本(ben)(ben)更(geng)低,安全性(xing)也要(yao)求(qiu)更(geng)高。

  動(dong)力鋰(li)(li)電(dian)(dian)池(chi)與儲能(neng)鋰(li)(li)電(dian)(dian)池(chi)有(you)一(yi)些(xie)區別(bie),但從電(dian)(dian)芯(xin)上(shang)看,都是一(yi)樣的,都可以采用磷酸(suan)鐵(tie)鋰(li)(li)電(dian)(dian)池(chi)和(he)三元鋰(li)(li)電(dian)(dian)池(chi),主要差別(bie)在于BMS電(dian)(dian)池(chi)管理系統,電(dian)(dian)池(chi)的功率響應速度和(he)功率特(te)性、SOC估算精度,充放電(dian)(dian)特(te)性等(deng),都可以在BMS上(shang)去實現。
