  • 電動汽車動力電池包布置集成研究

    鉛酸電池、鎳氫電池,再到鋰離子電池(鋰電池),車用動力電池也走過了漫長的過程。目前已經量產的鋰電池,其主要差異在產品的外形和正極材料,以下所闡述的分類對比正是圍繞這兩個方面來展開。

    中國鐵塔公司已停止采購鉛酸電池 改為采購鋰電池

    截至2018年底,已在全國31個省市約12萬個基站使用梯次電池約1.5GWh,替代鉛酸電池約4.5萬噸。

    蓄電池發明150年 電動汽車為何沒成主流

    法國人普蘭特于1859年發明鉛酸蓄電池,已經有160年的發展歷程。世界上第一輛電動汽車于1881年誕生,發明人為法國工程師古斯塔夫·特魯韋,是一輛用鉛酸電池為動力的三輪車。

    鋰電池威脅不可避免 鉛蓄電池生存空間遭擠壓!

    鋰電池和鉛酸電池是電動車最常見的動力來源,近年來鉛酸電池行業進行了一系列的改革整治,行業洗牌加速,同時鋰電池異軍突起,已經開始蠶食鉛蓄電池的市場份額。

    高效電池均衡器技術在梯次儲能蓄電池中的應用

    電池均衡技術可提高電池組的使用壽命、延長電池組的使用時間,適用于大容量鎳氫、2V鉛酸電池、鋰電池、6V鉛酸、12V鉛酸等電池組以及超級電容器組。

    喧囂再起 48V輕混或將于2020年前后迎來爆發期

    48V系統是指電壓為48伏,以能量小于1度電的功率型鋰離子電池替代傳統的鉛酸電池,用BSG電機替代傳統的啟動電機和發電機,除具備自動啟停功能外,還能在必要時提供輔助動力的輕混系統。

    動力電池報廢成新常態 市場廣闊卻道路坎坷

    動力電池的污染威脅,在于它報廢之后的后端處理環節。如果回收處置不當,它也極有可能重蹈當年鉛酸電池覆轍,對環境造成嚴重污染。我國新能源汽車及動力電池在回收、運輸、拆解、梯次利用等方面尚存短板,仍需補齊。

    從鋰電池分類,三分鐘了解動力電池主流技術

    新能源汽車的動力電池可以分為二次電池(包括鉛酸電池,鎳鎘電池,鎳氫電池,鋰電池)和燃料電池。

    不同種類電極和隔膜的烘干特性

    相比于傳統的鉛酸電池,鋰離子電池最大的不同點在于其電勢要明顯高于水的穩定電壓范圍,傳統的水溶液電解液無法應用在鋰離子電池中,因此人們開發了有機電解液體系,使得鋰離子電池能夠在高電壓下穩定的工作。

    48V系統市場及主流企業分析

    48V系統是指系統電壓為48V,用能量小于一度電的功率型鋰離子電池替代傳統的鉛酸電池,用BSG電機替代傳統的啟動電機和發電機,除了自動啟停功能之外,還能夠在必要的時候,為車輛提供輔助動力。

    32位在渝全國人大代表聯名建議: 將四輪低速電動車納入摩托車類別管理

    近日,全國人大代表、隆鑫控股有限公司董事局主席涂建華等32位在渝全國人大代表聯名提出建議,將四輪低速電動車納入摩托車類別管理,推動這個新產業的發展。

    國家認定鋰電低速電動是“正途”

    低速電動車的界定和管理本身就是千頭萬緒、錯綜復雜的工作,現在規范動力電池的問題又被推上風口浪尖。可以想見,未來國標的制定無論對低速電動車還是動力電池市場的發展,都將起到舉足輕重的作用。

    低速電動車國標制定遭炮轟 院士楊裕生:制定方不能取代市場當裁判

    在日前舉行的電動車百人會“低速電動車峰會”上,以楊裕生院士“低速電動車不應限定電池種類”的開場發言為導火索,直接向正在制定中的要求把鉛酸電池全部換成鋰離子電池的低速電動車國標開炮。

    低速電動車標準起草組組長董揚的思考:不允許用鉛酸電池

    但有人提出因為低速電動車寬度窄,所以放松側面碰撞要求,這不符合使用要求,不能采納。還有一個很大的焦點問題是低速電動汽車不允許使用鉛酸電池

    【解析】車用能量存儲技術的對比分析

    經過長期的演化,車用儲能電池技術也演化出了多種多樣的形式類別,有化學電池技術,超導儲能技術,機械飛輪技術等等,化學電池技術又包括鉛酸電池、鎳鉻電池、鎳氫電池等。
