特斯拉著手開發 110kWh 新型大電池,640 公里續航即將達標
證據顯示特斯拉正在開發 110 kWh 新型電池,馬斯克先前吐露的「640 公里」續航力目
標可望達成。
揭露消息的是特斯拉資深車主兼駭客 Jason Hughes,他曾在過去第一個爆料 P100D 車型
,現在 Hughes 又在特斯拉電池管理系統的程式碼中,發現了一個新露臉的「109kWh 可
用電量」電池資訊,當加入電池管理應有的緩衝區電量後,代表這組神秘的新型電池電量
將至少是 110kWh、或達到 115kWh。

Spent a little time RE'ing some recent Tesla BMS firmware.
Some variables were tweaked to fit 108 cell groups (~450V pack).
There is a packID that starts life set to ~109 kWh usable (400+ miles).
Bunch of other tweaks suggest prep for new S/X/3 pack configs at some point.
在去年底,知名駭客 @greentheonly 也挖出過一串程式碼,發現 Model 3 電池編成中意
外出現了 100kWh 版本,不過至今仍無進一步消息。
一般來說,在能量密度不變的情況下,高容量電池組勢必伴隨高重量與高成本,因此不是
單純搭載高容量電池組就可以換得期望的續航里程或實用性。而特斯拉已是目前擁有最先
進電控技術的車廠,在過去一直都是透過不斷優化軟體來提升續航力,本月 15 日特斯拉
才在美國更新了 Model S 與 Model X,將續航力提升最高 41 公里,並更名為 Long
Range Plus 版本。而特斯拉在收購 Maxwell 之後就一直有傳言他們會自行研發與製造電
池。因此若這次的新型電池可以提高能量密度,那麼在單次充電後的行駛里程勢必可以更
加突破。如此一來,距離馬斯克與許多車迷口中的「640 公里」(400mi) 續航目標就不會
太遠了。

心得/說明:(30字以上)
雖然大電池代表更貴的售價,但是時間拉長來看
代表未來車輛會有夠平價又充足的續航能力
只是目前應該還是貴到讓人下不了手
另外,儘管大電量伴隨的問題是充電需要充比較久
但如果電量夠一整天的通勤所需
那只要提高目的地充電的充電效率就可以排除很多充電問題了
