霜降已過，天氣也漸(jian)漸(jian)轉(zhuan)涼，對(dui)于燃油(you)車(che)而(er)言，這只不過是一個普通(tong)得不能(neng)再普通(tong)的節氣。但對于純(chun)電(dian)車而(er)言，到了冬季，續航是否還能和往常一樣？便成了車主們(men)共同頭疼的問題(ti)。

之所(suo)(suo)以純電(dian)(dian)(dian)(dian)動車在冬(dong)季(ji)續(xu)航會驟降，主要還是由于電(dian)(dian)(dian)(dian)池的(de)(de)特性所(suo)(suo)致，如今(jin)純電(dian)(dian)(dian)(dian)車大多(duo)采用的(de)(de)是鋰(li)電(dian)(dian)(dian)(dian)池，細分的(de)(de)話主要是磷酸鐵鋰(li)、三(san)元(yuan)鋰(li)和錳酸鋰(li)三(san)種(zhong)類(lei)型電(dian)(dian)(dian)(dian)池，而三(san)種(zhong)電(dian)(dian)(dian)(dian)池的(de)(de)工作(zuo)原理都基本相似，主要是化學反應(ying)來實現。因此，為(wei)(wei)了適應(ying)逐漸到來的(de)(de)冬(dong)季(ji)，在這里為(wei)(wei)大家總結了幾個方法。

1、及時充電確保安全

盡量保(bao)證(zheng)每天(tian)使(shi)用車(che)輛后及時充(chong)電(dian)，避(bi)免因(yin)電(dian)量過低(di)導致車(che)輛擱淺；充(chong)電(dian)前(qian)，養成良(liang)好的充(chong)電(dian)設備外觀檢查及車(che)輛充(chong)電(dian)口(kou)檢查習慣，尤其(qi)冬季(ji)充(chong)電(dian)，應確(que)(que)保(bao)使(shi)用環境通(tong)風、干燥，確(que)(que)保(bao)充(chong)電(dian)安全(quan)。

2、選擇溫度較高的環境下充電

無論(lun)停車(che)還是充(chong)(chong)(chong)(chong)電(dian)，有條件盡量(liang)選擇(ze)溫度相對較高(gao)的環境。冬(dong)季最好(hao)(hao)選擇(ze)白天(tian)充(chong)(chong)(chong)(chong)電(dian)，如果是陽(yang)光明媚的天(tian)氣更好(hao)(hao)。這有利(li)于提升(sheng)動力電(dian)池(chi)的活性，一方面減少(shao)續航里程(cheng)損失，另外充(chong)(chong)(chong)(chong)電(dian)效率、充(chong)(chong)(chong)(chong)電(dian)量(liang)等指(zhi)標也比低溫環境下更好(hao)(hao)。

3、堅持“隨用隨充”，避免深度放電

電(dian)(dian)(dian)(dian)池(chi)使用(yong)后馬上(shang)(shang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，因為冬(dong)天氣(qi)溫較低(di)，當(dang)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)芯低(di)于0攝氏(shi)度(du)(du)時，系統會先給電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)芯加熱，當(dang)其(qi)溫度(du)(du)達到5攝氏(shi)度(du)(du)以(yi)上(shang)(shang)時，才會開始給車輛充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。很多人覺得(de)，冬(dong)天給電(dian)(dian)(dian)(dian)動汽車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)變慢了，實際(ji)上(shang)(shang)是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)前(qian)又增加了一個給電(dian)(dian)(dian)(dian)池(chi)預(yu)熱的時間(jian)。因此(ci)，建議車主采(cai)取“隨(sui)用(yong)隨(sui)充(chong)(chong)(chong)”原則，車輛使用(yong)完畢后立即進行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，因為此(ci)時電(dian)(dian)(dian)(dian)池(chi)溫度(du)(du)相對較高，可以(yi)提高充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)效(xiao)率。

4、合理利用空調暖風

作為能耗大戶的空調暖風同樣可以適當把風量和溫度調低一點，并且盡量用座椅加熱和方向盤加熱來代替取暖，在保持身體溫暖的同時，又可以最大限度地減輕空調開啟后耗電過快的現象。

當然了，即便做完了以上幾(ji)個(ge)步驟，也無法徹底避免(mian)冬天續(xu)航里(li)程的下滑趨勢(shi)。因(yin)此，更重要的還(huan)是規劃好出行路線(xian)以及熟知充電(dian)(dian)站(zhan)分布，避免(mian)駕(jia)駛(shi)里(li)程過長，無法找到(dao)充電(dian)(dian)站(zhan)進行充電(dian)(dian)。
