UPS電(dian)(dian)源采用鋰電(dian)(dian)池(chi)(chi)供電(dian)(dian)比鉛(qian)(qian)酸(suan)電(dian)(dian)池(chi)(chi)好(hao)在哪?現在市面上(shang)有(you)的電(dian)(dian)池(chi)(chi)就是兩種,鋰電(dian)(dian)池(chi)(chi)和鉛(qian)(qian)酸(suan)電(dian)(dian)池(chi)(chi)，UPS鋰電(dian)(dian)池(chi)(chi)以其(qi)安全性、量較(jiao)輕、長壽(shou)命、電(dian)(dian)徹底(di)、維護保養低成本、無記憶(yi)性等(deng)特性,快速攻占了銷(xiao)售市場，正慢(man)慢(man)替代傳統式的鉛(qian)(qian)酸(suan)蓄(xu)電(dian)(dian)池(chi)(chi)。吁今(jin)后的鋰電(dian)(dian)池(chi)(chi)發展,前景究竟會怎么樣呢(ni)？

UPS鋰(li)電(dian)池(chi)供(gong)電(dian)比鉛(qian)酸(suan)電(dian)池(chi)好在哪(na)？

數(shu)據中(zhong)心在信(xin)息化時代的(de)作(zuo)用愈(yu)加重(zhong)要(yao),面(mian)對云(yun)計(ji)算、物聯(lian)網(wang)所(suo)帶來的(de)海(hai)星數(shu)據業務,想要(yao)保持穩定、可靠(kao)運維,數(shu)據中(zhong)心就(jiu)需要(yao)有較高(gao)品質的(de)鋰電池UPS電源作(zuo)為基礎(chu)支撐。

就現在市場上的(de)全體(ti)狀(zhuang)況而(er)(er)言, UPS電源(yuan)大(da)都使用鋰(li)電池(chi)(chi)而(er)(er)非鉛酸蓄電池(chi)(chi),導致呈現這種(zhong)狀(zhuang)況的(de)原因是(shi)什么(me)呢？鋰(li)電池(chi)(chi)與(yu)鉛酸蓄電池(chi)(chi)究(jiu)竟差異在哪里，存能電氣小(xiao)編帶(dai)著我們(men)走進這個論題。

1.鋰(li)電(dian)(dian)占(zhan)地(di)(di)面(mian)積(ji)少,省空(kong)間(jian)機(ji)柜(ju)放(fang)的(de)多鋰(li)電(dian)(dian)池(chi)能量體積(ji)密度200~. 300W/L ,鉛酸電(dian)(dian)池(chi)只(zhi)有(you)60~90W/L ,滿足(zu)相同備電(dian)(dian)時間(jian)要(yao)求(qiu)時,需要(yao)的(de)鋰(li)電(dian)(dian)池(chi)占(zhan)地(di)(di)面(mian)積(ji)比鉛酸電(dian)(dian)池(chi)少2/3,有(you)限的(de)空(kong)間(jian)可(ke)以放(fang)置更(geng)多的(de)電(dian)(dian)池(chi)滿足(zu)備電(dian)(dian)要(yao)求(qiu),同時,對于數據(ju)中(zhong)心(xin)主機(ji)托管的(de)客戶來說(shuo),鋰(li)電(dian)(dian)池(chi)節省的(de)空(kong)間(jian)支(zhi)持(chi)放(fang)置更(geng)多的(de)機(ji)柜(ju),幫升效益。

2.鋰電重(zhong)量(liang)為1/3 ,承(cheng)重(zhong)要求(qiu)低(di),地(di)板承(cheng)重(zhong)免改(gai)(gai)造鋰電池(chi)(chi)能(neng)量(liang)重(zhong)量(liang)密度100~ 150W/kg ,鉛酸(suan)電池(chi)(chi)只(zhi)有30~ 50W/kg ,滿足(zu)相同(tong)備電時間(jian)要求(qiu)時,需(xu)要的鋰電池(chi)(chi)重(zhong)量(liang)比鉛酸(suan)少2/3 ,對地(di)板承(cheng)重(zhong)要求(qiu)更低(di),容易選(xuan)址,地(di)板承(cheng)重(zhong)不(bu)需(xu)要改(gai)(gai)造。

3.鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)壽命(ming)(ming)長2~ 3倍, 10~15年生命(ming)(ming)周(zhou)期(qi)內不(bu)需要替換(huan)(huan)在電(dian)(dian)(dian)(dian)(dian)網環(huan)境(jing)比較好的場景,鋰電(dian)(dian)(dian)(dian)(dian)使用壽命(ming)(ming)可(ke)(ke)(ke)達10~15年, 鉛(qian)酸電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)-般4~6年更換(huan)(huan)一 次。相比鉛(qian)酸電(dian)(dian)(dian)(dian)(dian)池(chi)(chi),鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)10年內可(ke)(ke)(ke)以不(bu)用更換(huan)(huan),進而提高(gao)供(gong)電(dian)(dian)(dian)(dian)(dian)可(ke)(ke)(ke)靠性(xing),簡化(hua)運維,降低OPEX ,并彌(mi)補供(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)統壽命(ming)(ming)短板(ban)。

4.鋰(li)電(dian)(dian)循(xun)環次數(shu)多(duo), 3~ 10倍(bei),充(chong)(chong)(chong)放(fang)(fang)電(dian)(dian)快,新能源儲(chu)能應用(yong)多(duo)鋰(li)電(dian)(dian)池(chi)循(xun)環可支(zhi)持(chi)幾千次的(de)循(xun)環充(chong)(chong)(chong)放(fang)(fang)電(dian)(dian),是(shi)鉛酸電(dian)(dian)池(chi)的(de)3~ 10倍(bei),在(zai)電(dian)(dian)網不(bu)好的(de)場(chang)景(jing)可以保證更長的(de)使用(yong)壽命; 同時鋰(li)電(dian)(dian)池(chi)可支(zhi)持(chi)大電(dian)(dian)流充(chong)(chong)(chong)電(dian)(dian),電(dian)(dian)更快,充(chong)(chong)(chong)電(dian)(dian)時間可縮短到1 ~2H ,相比鉛酸電(dian)(dian)池(chi)快4~5倍(bei), 在(zai)太(tai)陽(yang)能發電(dian)(dian),削峰(feng)錯谷等(deng)儲(chu)能場(chang)景(jing)應用(yong)廣(guang)泛。

5.鐵鋰(li)電(dian)(dian)(dian)池(chi)環保型,而鉛(qian)(qian)(qian)酸(suan)(suan)電(dian)(dian)(dian)池(chi)屬(shu)于非環保型電(dian)(dian)(dian)池(chi)鋰(li)電(dian)(dian)(dian)池(chi)不含任何重金(jin)屬(shu)與(yu)稀(xi)有金(jin)屬(shu),無毒,無論在(zai)(zai)生(sheng)產汲使用中均無污(wu)染(ran),符合歐洲RoHS規定,為綠色環保電(dian)(dian)(dian)池(chi)。鉛(qian)(qian)(qian)酸(suan)(suan)蓄電(dian)(dian)(dian)池(chi)中存在(zai)(zai)著大(da)(da)量(liang)的(de)鉛(qian)(qian)(qian),在(zai)(zai)廢棄后(hou)若處(chu)理不當,將對環境產生(sheng)污(wu)染(ran),所(suo)以從國家政策導向(xiang)來講,已(yi)經(jing)在(zai)(zai)限(xian)制鉛(qian)(qian)(qian)酸(suan)(suan)電(dian)(dian)(dian)池(chi)的(de)擴大(da)(da)再(zai)投(tou)資,或(huo)在(zai)(zai)某些領域(yu)限(xian)制鉛(qian)(qian)(qian)酸(suan)(suan)電(dian)(dian)(dian)池(chi)的(de)使用,未(wei)來鋰(li)電(dian)(dian)(dian)池(chi)替換(huan)鉛(qian)(qian)(qian)酸(suan)(suan)電(dian)(dian)(dian)池(chi)的(de)趨勢(shi)會(hui)越發(fa)明(ming)顯。

鋰電(dian)(dian)池(chi)(chi)與鉛(qian)酸電(dian)(dian)池(chi)(chi)相比較安(an)全(quan)(quan)性(xing)能鋰電(dian)(dian)池(chi)(chi)的組成資(zi)(zi)料相較于(yu)鉛(qian)酸電(dian)(dian)池(chi)(chi),穩定性(xing)更高。在高溫或許過充(chong)的狀況下(xia),鋰電(dian)(dian)池(chi)(chi)的資(zi)(zi)料不會(hui)發(fa)作結構(gou)(gou)坍塌或是(shi)構(gou)(gou)成強氧化(hua)性(xing)物(wu)質。過度放電(dian)(dian)時,鉛(qian)酸電(dian)(dian)池(chi)(chi)極板會(hui)發(fa)作硫化(hua)而導致電(dian)(dian)池(chi)(chi)品突(tu)變(bian)劣,因而鋰電(dian)(dian)池(chi)(chi)的安(an)全(quan)(quan)性(xing)要強于(yu)鉛(qian)酸電(dian)(dian)池(chi)(chi)。

二、本錢差異

同等(deng)容量(liang)下(xia),鋰電(dian)池的(de)(de)體積(ji)和分量(liang)均(jun)為(wei)鉛酸(suan)電(dian)池的(de)(de)三分之一(yi), 能夠有用的(de)(de)節省(sheng)裝置空間(jian),不需要過多的(de)(de)考慮(lv)樓板的(de)(de)承重。

鋰(li)電池(chi)(chi)不需要像(xiang)鉛酸(suan)電池(chi)(chi)-樣短(duan)時間內頻繁進行保(bao)(bao)護,且(qie)鋰(li)電池(chi)(chi)的循環使(shi)用壽命(ming)也比鉛酸(suan)電池(chi)(chi)高(gao)幾倍(bei)。鉛酸(suan)電池(chi)(chi)還需要有空調來調控全(quan)體(ti)的環境(jing),但高(gao)端的鋰(li)電池(chi)(chi)UPS自身(shen)就(jiu)帶(dai)有很多調節(jie)的功用,能減少很大一部分(fen)附加設備購買費(fei)、 保(bao)(bao)護費(fei)以及電費(fei)。

盡管兩(liang)者的購買本錢相比較,是鉛酸電池(chi)低于鋰電池(chi),但(dan)從長(chang)時間的使用考慮,鋰電池(chi)的整體(ti)本錢要低于鉛酸電池(chi)。

相比(bi)傳統鉛酸蓄電(dian)(dian)池(chi)(chi)體(ti)積大、能耗(hao)(hao)高(gao)、維護困難(nan)、難(nan)以擴容,具有(you)重量輕(qing)、能耗(hao)(hao)低(di)、壽命(ming)長(chang)、維護簡單、可靈(ling)活快速部署的(de)鋰電(dian)(dian)池(chi)(chi)解決方案能夠為(wei)數(shu)據中心帶(dai)來更(geng)可靠(kao)的(de)供(gong)電(dian)(dian)保障。 不難(nan)看出, UPS鋰電(dian)(dian)池(chi)(chi)儲(chu)能,將成(cheng)為(wei)未來的(de)發(fa)展趨勢。

鋰(li)電(dian)池原材(cai)料的(de)(de)應用(yong)(yong)徹底繞開(kai)了鉛酸蓄電(dian)池產生的(de)(de)各(ge)種(zhong)各(ge)樣危害(hai)，高效(xiao)率能量(liang)相(xiang)對(dui)密度, 小容積 ,輕(qing)品質,壽命長,寬溫度范(fan)圍等優(you)勢讓銷售市場“亂倒”了它。選用(yong)(yong)鋰(li)電(dian)UPS供配(pei)電(dian)系統(tong)的(de)(de)優(you)點愈來愈顯著, 鋰(li)電(dian)池的(de)(de)建設規劃也被愈來愈多(duo)的(de)(de)公(gong)司(si)選用(yong)(yong),大家見到鋰(li)電(dian)正(zheng)逐漸變成大數據中心(xin)主機房必不可(ke)少的(de)(de)新(xin)朋友。
