勤充電(dian)對蓄(xu)電(dian)池壽命(ming)的影響

電(dian)池是(shi)(shi)勤(qin)充電(dian)好還是(shi)(shi)放完電(dian)再充電(dian)好？由(you)于放電(dian)越深越淺，其(qi)循環(huan)次數將大(da)幅度(du)增加。因而，按這(zhe)一理論(lun)，勤(qin)充電(dian)對循環(huan)壽命是(shi)(shi)有益(yi)的，但就目前市場上大(da)量流通運用的充電(dian)器來講，由(you)于受(shou)價錢(qian)要素及技術程度(du)等影響，充電(dian)器存在毛(mao)病率高，牢靠(kao)性差，精度(du)低等缺陷(xian)。

因而(er)，有時勤充(chong)(chong)電(dian)(dian)(dian)(dian)反而(er)影響電(dian)(dian)(dian)(dian)池的運用壽命。將電(dian)(dian)(dian)(dian)池放(fang)空(kong)再充(chong)(chong)電(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)次(ci)數固然減少，但放(fang)電(dian)(dian)(dian)(dian)時由于(yu)單體電(dian)(dian)(dian)(dian)池之間總會(hui)存在差別可能形成某(mou)些單格(ge)過(guo)放(fang)電(dian)(dian)(dian)(dian)，過(guo)放(fang)電(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)承受才能會(hui)大大降低，惹(re)起(qi)充(chong)(chong)電(dian)(dian)(dian)(dian)缺乏的毛病(bing)，另(ling)外由于(yu)放(fang)完電(dian)(dian)(dian)(dian)再充(chong)(chong)電(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)重視負荷時間長，易損壞充(chong)(chong)電(dian)(dian)(dian)(dian)器。

因(yin)(yin)而(er)(er)，綜合上(shang)述，我們以為蓄電(dian)(dian)(dian)(dian)(dian)池(chi)放出電(dian)(dian)(dian)(dian)(dian)量的(de)50-70%時停止一次充電(dian)(dian)(dian)(dian)(dian)是較合理(li)的(de)，對電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)運用有益處。溫(wen)(wen)度(du)(du)(du)對電(dian)(dian)(dian)(dian)(dian)池(chi)性能有什么影響(xiang)？電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充電(dian)(dian)(dian)(dian)(dian)、放電(dian)(dian)(dian)(dian)(dian)時，在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)發作電(dian)(dian)(dian)(dian)(dian)化學反響(xiang)，溫(wen)(wen)度(du)(du)(du)越(yue)高，電(dian)(dian)(dian)(dian)(dian)池(chi)各活性物質的(de)活度(du)(du)(du)增加，電(dian)(dian)(dian)(dian)(dian)解液粘(zhan)度(du)(du)(du)降低(di)(di)，電(dian)(dian)(dian)(dian)(dian)阻(zu)減小，因(yin)(yin)而(er)(er)電(dian)(dian)(dian)(dian)(dian)化學反響(xiang)容(rong)易(yi)停止，反之則不容(rong)易(yi)停止。放電(dian)(dian)(dian)(dian)(dian)時溫(wen)(wen)度(du)(du)(du)越(yue)低(di)(di)，放出容(rong)量越(yue)低(di)(di)，在(zai)(zai)特別低(di)(di)的(de)溫(wen)(wen)度(du)(du)(du)下，放出容(rong)量將(jiang)大幅度(du)(du)(du)降落，溫(wen)(wen)度(du)(du)(du)高則相反；充電(dian)(dian)(dian)(dian)(dian)時溫(wen)(wen)度(du)(du)(du)越(yue)低(di)(di)，充電(dian)(dian)(dian)(dian)(dian)承(cheng)(cheng)受才能越(yue)差，請求充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓較高，才干充足電(dian)(dian)(dian)(dian)(dian)。反之溫(wen)(wen)度(du)(du)(du)越(yue)高，充電(dian)(dian)(dian)(dian)(dian)承(cheng)(cheng)受才能越(yue)好，易(yi)形成(cheng)(cheng)過充電(dian)(dian)(dian)(dian)(dian)，因(yin)(yin)而(er)(er)請求降低(di)(di)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓，才不至于形成(cheng)(cheng)過充電(dian)(dian)(dian)(dian)(dian)。

此(ci)溫度的變化，直接影響電池充(chong)電和(he)放電性能(neng)。
