想買車再等等!新型電池來了,壽命150萬公裡,還是中國造!

想買車再等等!新型電池來了,壽命150萬公裡,還是中國造!

動力電池是新能源汽車的核心組成部分,其壽命對于車主和整個行業來說至關重要。而很多人之是以不願意買新能源汽車的原因就是,覺得動力電池的壽命還達不到預期,抱着三四年就要換電池的人,還不在少數。

锂離子電池在充放電過程中,由于電解質的失活和變質,锂離子的流通阻力逐漸增大,進而導緻電池壽命降低。一次循環指電池滿充滿放一次。理論上,锂電池的循環壽命在800-1500次左右。但是這隻是理論壽命,很多人覺得這個循環壽命依然是不夠長。

對此,各大車企也在不斷努力去提高動力電池的壽命,最近,廣汽宣布要釋出一款新電池,它的循環壽命可以達到4000次,裡程壽命可以達到150萬公裡,這種電池被廣汽命名為“因湃電池”。

“因湃電池”是廣汽全棧自研自産的動力電池,将于本月的12号釋出,在此之前,行業内同類型最好的電池包擁有120萬公裡的壽命,循環次數有3000次,但是這隻是理論上的壽命,而且,動力電池的衰減問題,往往在車輛上了年限之後開始凸顯,當電池容量衰減超過20%之後,就會明顯影響用車體驗,即使電池壽命依然沒有到,但是對于車主而言也隻是雞肋了。

而廣汽的因湃電池4000次的循環次數,假設滿電續航是500千米,即使打六折,也可以行駛150萬公裡以上,假設1天完整充放電一次,4000次的循環次數,也足夠車主開上10年以上了,而且現實中很少有人每天都要充放電,對于網約車司機而言,這将是一大利好,至少七八年不需要換電池了,而對于家用車而言,基本上不可能開到理論壽命。

因湃電池采用的是磷酸鐵锂電芯,這種電芯本身就比三元锂電池有着更長的充放電壽命,但是能量密度稍低,而在廣汽的努力下,全新電池的整包能量密度能夠達到146.5Wh/kg,足以滿足中低端車型的需求了。此外該款電池的安全标準達到了軍工級别,官方稱即使受到槍擊,整包電池也不會起火。

廣汽一直在動力電池的技術方面,有着比較深的底蘊,之前研發的彈匣電池,就有着出色的安全性,在廣汽AION搭載的幾十萬車上,無一輛發生自燃,是以,廣汽這款新電池的表現,确實值得期待。
