BMW 預告純電車續航力能衝上一千公里,Neue Klasse 平台最大可搭 150kWh 電池
雖然首款產品預計 2025 年才會推出,但 BMW 針對未來純電車產品主力平台「Neue
Klasse」 (德語 New Class 的意思) 的宣傳行銷近來動作不斷。日前對外預告要於
2023 年 CES 公開展示 Neue Klasse 平台概念車之後,BMW 高層進一步透露此平台的規
格特點,預告 Neue Klasse 平台純電車續航力最高能衝上一千公里。
BMW 宣告 Neue Klasse 電動車要用 46mm 大型圓柱狀電池,充電速度、續航力都能飆升
30%

寧德時代全新圓柱型電池於 2025 年開始供應 BMW Neue Klasse 新世代電動車
(原文連結:https://bit.ly/3EqeLGU )
BMW 的技術總監 Frank Weber 日前在接受媒體採訪時透露,Neue Klasse 平台將使用的
圓柱狀電池有和現行車款採用的技術相比,有著能量密度提升 20%、續航里程提高 30%、
充電速度提高 30% 的特點,同時還有重量減輕 20%、生產成本降低 50%,以及生產過程
中碳排放量減少 60% 等多重優勢。
Neue Klasse 平台在電池、馬達、車身大小的支援型也頗為廣泛,透過 Neue Klasse 平
台打造的車款最多可容納四組電動馬達,可對應 75kWh 到 150kWh 的電池容量,並且能
夠提供最高達 1,000 公里的超長續航力。
但即便 Neue Klasse 平台純電車有著能配置大容量電池,讓續航力上看 1,000 公里的能
耐,BMW 卻不一定會真的推出有著如此高續航力的車。Weber 指出相對於一昧加大電池容
量,BMW 打算專注於進一步改善空氣動力學表現,或是提高電動車的整體能耗源效率表現
。
順帶一提,Neue Klasse 平台車款也將支援 800V 高壓架構,和高性能充電器的搭配之下
,Weber 表示只要充電 1 分鐘就可補進 48 公里的續航里程,意味著只需大約花費 12
分鐘即可把電量從 0% 充到 95%。
先前 BMW 透露首波採用 Neue Klasse 平台打造的 BMW 車款,將會是新世代的 3 系列。
但 BMW 計畫在 2023 年 1 月 CES 公開展示的 Neue Klasse 平台「Vision Vehicle」,
並不一定就是 3 系列新世代純電車型的先行預覽,外界預期 BMW 主要是打算先行展示未
來純電新車的設計理念。
心得/說明:(30字以上)
目前 iX 和 i4 的能源效率其實不算太差
但是 Neue Klasse 採用 4695 電池與 800V 充電架構
終於符合他們一直以來的技術力與品牌定位
不過這篇文章當中有兩點挺有趣
首先,BMW 技術總監認為透過加大電池達到續航里程 1000km 不是優先選項
而是應該從能耗與風阻係數改善下手
對照多年前 Elon Musk 也說過一樣的話...
當時很多人的說法是認為那是技術力不夠的閃躲之詞
再來,當初 Tesla 推出 4680 電池
有些人一直說那個電池沒甚麼創新可言
結果現在 BMW 要採用 4695 和 46120 兩種電池
也是可以讓製造成本降低、能量密度與充電速度提升.. 多種優點
或許有人會說 4695 和 46120 不是 4680
私以為應該是為了躲避 4680 技術專利而產生的變型
不然 46 直徑是什麼了不起的魔術數字
使得 CATL 這樣的技術大廠推出的新電池技術也這麼剛好只能用到 46 直徑?
題外話
印象中 Model Y 主打的壓鑄製程,好像也有別的車廠打算跟進
似乎一次又一次驗證「先驅總是孤獨的」這句話呢
