太陽能路燈充電時的管理

    太(tai)陽能路燈蓄電(dian)池(chi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)沖完(wan)電(dian)后(hou)，馬上(shang)用手摸蓄電(dian)池(chi)的(de)外(wai)殼(ke)就有(you)發(fa)燙的(de)感覺(jue)，這說明充電(dian)時溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)上(shang)升(sheng)。但是，溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)（電(dian)解(jie)液(ye)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)）升(sheng)得過(guo)高，蓄電(dian)池(chi)壽命(ming)會(hui)明顯縮(suo)(suo)短(duan)，這是因為(wei)蓄電(dian)池(chi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)升(sheng)高，陰、陽極(ji)板上(shang)的(de)活(huo)性物質(zhi)就會(hui)劣(lie)化，陽極(ji)各(ge)自收到腐蝕，縮(suo)(suo)短(duan)電(dian)池(chi)壽命(ming)。蓄電(dian)池(chi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)也(ye)不能太(tai)低(di)，溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)過(guo)低(di)，會(hui)使(shi)(shi)蓄電(dian)池(chi)容(rong)量減少，容(rong)易過(guo)度(du)(du)(du)(du)(du)(du)放電(dian)，使(shi)(shi)電(dian)池(chi)壽命(ming)縮(suo)(suo)短(duan)。通(tong)常蓄電(dian)池(chi)的(de)電(dian)解(jie)液(ye)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)應維持在15～55℃為(wei)理想使(shi)(shi)用狀態(tai)，特殊情況(kuang)，也(ye)不可超過(guo)放電(dian)時-15～55℃這個溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)范圍(wei)，充電(dian)時0～60℃的(de)范圍(wei)。放電(dian)終(zhong)了時，電(dian)解(jie)液(ye)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)維持在40℃以下最好。

    充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)量 太陽能(neng)路燈蓄(xu)電(dian)(dian)(dian)(dian)池(chi)的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)量與(yu)放電(dian)(dian)(dian)(dian)量之比不能(neng)過高，若過高易使(shi)水分解，氣體產(chan)生，電(dian)(dian)(dian)(dian)解液明顯(xian)減少，會使(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時溫度上(shang)升，蓄(xu)電(dian)(dian)(dian)(dian)池(chi)壽命(ming)縮(suo)短。此外，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)不足(zu)又(you)重復放電(dian)(dian)(dian)(dian)使(shi)用(yong)，則會嚴重影響電(dian)(dian)(dian)(dian)池(chi)壽命(ming)。
