2PbSO4+2H2O充電普通鉛酸蓄電池充電過(guò)程中伴隨著副反應(yīng)①:2H2O 2H2↑+O2↑①該反應(yīng)使電池中水分逐漸損失,需不斷補(bǔ)充純水才能保持正常使用。LSA系列電池采用貧液設(shè)計(jì),選用AGM隔板(超細(xì)玻璃纖維隔板),在正負(fù)極之間預(yù)留氣體通道,同時(shí)選用特殊合金鑄造板柵提高負(fù)極的析氫過(guò)電位,以抑制氫氣的析出。而正極產(chǎn)生的氧氣順著通道擴(kuò)散到負(fù)極,使氧氣重新復(fù)合成水,反應(yīng)如②、③式:2Pb+O22PbO

xù)增加。環(huán)境溫度的升高,也將加速電池板柵的腐蝕和電池水分的損失,從而大大縮短電池的壽命。圖3-1容量與溫度關(guān)系曲線(xiàn)3.2浮充電壓與溫度的關(guān)系選擇特定的浮充電壓是為了使電池在最好的狀態(tài)下運(yùn)行。如果浮充電壓過(guò)高,電池的浮充電流隨之增大,加快板柵腐蝕速度,降低電池使用壽命;浮充電壓過(guò)低,電池不能維持充足電狀態(tài),引起硫酸鹽化,容量減少,也會(huì)降低電池的使用壽命。在25℃下,南都電池的單體浮充電壓為2.23V,溫度補(bǔ)償系數(shù)為-3mV/℃只。表3-2不同溫度溫度下浮充電壓設(shè)置表環(huán)境溫度(℃)浮充電壓(V/只)1~52.296~102.2811~152.2616~202.2521~252.2326~302.2231~352.2036~402.193.3均充電壓與溫度的關(guān)系閥控式鉛酸電池需要定期進(jìn)行均衡充電,以保證電池正常運(yùn)行,在25℃下,南都電池單體的均充電壓為2.35V。同樣,均充電壓需要隨環(huán)境溫度進(jìn)行調(diào)整,電池均充電壓的溫度補(bǔ)償系數(shù)為-5mV/℃只。表3-3不同環(huán)境溫度下均充電壓設(shè)置表環(huán)境溫度(℃)均充電壓(V/只)1~52.456~102.4311~152.4016~202.3821~252.3526~302.3331~352.3036~402.28圖3-2浮充、均充電壓-溫度曲線(xiàn)3.4壽命與溫度的關(guān)系圖3-2浮充、均充電壓-溫度曲線(xiàn)溫度升高會(huì)損壞電池,降低電池的使用壽命,當(dāng)環(huán)境溫度超過(guò)25℃時(shí),溫度每升高10℃,電池使用壽命將減少一半,例如電池設(shè)計(jì)壽命在25℃為10年,在35℃下長(zhǎng)期運(yùn)行,壽命只有5年。有如下公式:L25=LT×2(T-25)/10其中:T為電池在實(shí)際運(yùn)行時(shí)的環(huán)境溫度;LT為在環(huán)境溫度為T(mén)時(shí),電池的設(shè)計(jì)壽命;L25為在環(huán)境溫度為25℃時(shí),電池的設(shè)計(jì)壽命應(yīng)該控制電池使用的環(huán)境溫度,閥控式密封鉛酸蓄電池的散熱條件比較差,當(dāng)熱量積累到一定程度后會(huì)損壞電池,嚴(yán)重時(shí)會(huì)引起熱失控。若室內(nèi)溫度過(guò)高則必須適當(dāng)通風(fēng)、改善環(huán)境溫度,電池間距不要低于10mm,同時(shí)按手冊(cè)要求調(diào)節(jié)電池的浮充電壓和均充電壓值。4.充放電要求4.1均衡充電下列情況下需對(duì)電池組均衡充電:a電池組中有兩只以上電池電壓低于2.18V;b電池浮充運(yùn)行超過(guò)三個(gè)月。均衡充電的方法為恒壓限流法:以不超過(guò)0.1C10A的恒電流對(duì)電池組充電,到電池平均電壓上升到2.35/只(25℃),然后改用2.35V/只恒壓充電,均衡充電時(shí)間為15小時(shí)。4.2電池充電下列情況下需對(duì)電池組充電,充電方法同
