電動車的電池使用一段時間后，很多消費者就發現，電池越來越不好用了，跑不了多長時間就沒電了，到底是怎么回事呢?澳柯瑪電動車小編來解答。
　　1.在電動車電池使用及充放電過程中，會出現“硫化”現象影響電池容量。 硫化是指電池在使用過程中由于電化學反應，極板會逐漸被堅硬的硫酸鉛結晶覆蓋，導致活性極板面積逐步減少及酸液濃度降低而使得電池容量下降。
　　2.冬夏季電動車電池充電電壓不同，如無合適的能隨環境變壓調整的充電器，將使得夏季電池過充引起電池失水最終導致電池鼓包、變形，或者冬季欠充出現行駛里程下降。
　　3.由于電動車使用及電池出廠配伍誤差等多種因素，串連電池間將出現電壓不均衡，電池容量將受制于最低電壓的那個電池。
