AGV小車是指配備自動引導設備的運輸車輛，可沿常規引導途徑行駛，具有安全防護和各種移動功能。在工業應用中，不需要駕駛員的載體使用可充電電池作為其電源。

　　AGV汽(qi)車(che)鋰電(dian)池的(de)正常(chang)使(shi)用(yong)壽(shou)命(ming)一般在2-3年左右，但使(shi)用(yong)時間超過4年.五年，甚至六年。事(shi)實(shi)上，電(dian)池的(de)使(shi)用(yong)壽(shou)命(ming)與我們通常(chang)的(de)維護和(he)保護以及電(dian)池的(de)使(shi)用(yong)方式(shi)密(mi)切相關。我們可以從以下(xia)幾點來判斷電(dian)池是否應該(gai)更換。

　　1、看外觀

　　調(diao)查AGV汽車鋰電(dian)(dian)(dian)池兩側是(shi)否有(you)明顯的膨脹變(bian)形或凸起。調(diao)查電(dian)(dian)(dian)池樁頭周圍是(shi)否有(you)類似粉末(mo)的白色或綠色物(wu)體。事實上，這些(xie)是(shi)電(dian)(dian)(dian)池的氧(yang)化(hua)物(wu)。這些(xie)氧(yang)化(hua)物(wu)通常(chang)不(bu)容易出現在(zai)較好或新電(dian)(dian)(dian)池中。一旦出現，也意味(wei)著電(dian)(dian)(dian)池的性能已經(jing)開始出現問題。

　　2、看調查口

　　現在有超過80%的免保護AGV汽車的鋰(li)電(dian)(dian)池都有電(dian)(dian)動調(diao)查口。調(diao)查口一般可(ke)以看到三種顏(yan)色:綠色:.黃(huang)色和(he)黑色。綠色代(dai)表(biao)充足的電(dian)(dian)力，黃(huang)色代(dai)表(biao)輕微(wei)的電(dian)(dian)力損失，黑色代(dai)表(biao)即將報(bao)廢的需求更換(huan)。見電(dian)(dian)池上的標簽提示。

　　3、測電壓

       電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)由電(dian)(dian)(dian)(dian)池(chi)測量儀或萬(wan)用表測量。正常情況下，AGV汽車(che)鋰(li)電(dian)(dian)(dian)(dian)池(chi)的空(kong)載電(dian)(dian)(dian)(dian)壓(ya)(ya)約為13伏(fu)，滿載電(dian)(dian)(dian)(dian)壓(ya)(ya)一般(ban)不低于12伏(fu)，起(qi)動電(dian)(dian)(dian)(dian)壓(ya)(ya)不低于9伏(fu).5伏(fu)。如果電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)過低，很可能會出現起(qi)動困難或無法起(qi)動的情況。
