eps消防應急(ji)電(dian)源是在市(shi)電(dian)斷電(dian)的情況(kuang)下為(wei)樓道應急(ji)照明設備(bei)提供應急(ji)電(dian)源，其中蓄電(dian)池作(zuo)為(wei)EPS應急電源的核心部件，在(zai)EPS消防(fang)應(ying)急電(dian)源供(gong)電(dian)系統(tong)中起著至關重要的作用，下(xia)面就由邁雅電(dian)氣為您(nin)分享(xiang)一下(xia)eps電源蓄電池使用方面的基礎知識(shi)。

1. 電池容量計算。 一：輸出功率W/電池額定總電壓V，得結果多少A。 二：多少A*1.6，得結果放電1小時的容量AH。 舉例：2節1KW，應急30分鐘，求電池容量？ 解：1000W/24V=41A。 41A*1.6=66AH（60分鐘） 66AH/2=33AH（30分鐘）

2. 電池(chi)放電。 國標規定：電池(chi)放電電流不應大于電池(chi)容量的60％。如電池容量為100AH時，放(fang)電電流(liu)不能超(chao)過60A。放電(dian)電(dian)流過大時，會使(shi)電(dian)池(chi)(chi)發熱，當電(dian)池(chi)(chi)溫(wen)升到一定程度，將導致電(dian)解液(ye)受熱膨脹(zhang)蒸發，易損壞電(dian)池(chi)(chi)，甚至發生著火(huo)暴炸。

3. 電(dian)(dian)池充電(dian)(dian)。 國標規定：電(dian)(dian)池充電(dian)(dian)電(dian)(dian)流不(bu)應大于電(dian)(dian)池容量的40％。如電池容量為100AH時(shi)，充電(dian)電(dian)流不能(neng)超過40A。還(huan)要(yao)求在48小時內充飽電。

4. 電(dian)(dian)(dian)(dian)池截止(zhi)電(dian)(dian)(dian)(dian)壓(ya)。 電(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)時，其電(dian)(dian)(dian)(dian)壓(ya)會不斷(duan)下(xia)降，國標規定：當電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)下(xia)降到額定電(dian)(dian)(dian)(dian)壓(ya)的90％時應停止放電(dian)(dian)。電(dian)(dian)池電(dian)(dian)壓90％額定值叫(jiao)電(dian)池(chi)截止電(dian)壓。放電(dian)時低于90％還在放(fang)，叫電(dian)(dian)(dian)(dian)池過放(fang)電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)池過放(fang)電(dian)(dian)(dian)(dian)對電(dian)(dian)(dian)(dian)池壽命違害(hai)極大(da)，輕則(ze)損壞充電(dian)(dian)(dian)(dian)器，重(zhong)則(ze)使電(dian)(dian)(dian)(dian)池折壽甚至報費。閑置的(de)電(dian)(dian)(dian)(dian)池可通過潮濕的(de)空(kong)氣自然放(fang)電(dian)(dian)(dian)(dian)，一(yi)般(ban)應每(mei)3個月充(chong)飽電一次。EPS機用(yong)電池在不(bu)開機的情(qing)況下(xia)，應注意每1個月內致少充飽電一次(ci)。
