推 ccc101419 : 不過電動車是比較特別一些，IIHS撞測一般車油箱大 10/16 12:36
→ ccc101419 : 概都是空的拖著撞，大概幾乎沒有起火可能，但是電 10/16 12:37
→ ccc101419 : 動車只要有電池撞擊就多一層顧慮，所以我才會以為他 10/16 12:37
→ ccc101419 : 們單純車體測鋼性，應該是我沒看懂，抱歉 10/16 12:37
推 maniaque : 這次我是支持 Scape ,但官方確實有可能不放電池 10/16 13:49
→ maniaque : 或者放的是跟電池同樣重量的 Dummy battery 10/16 13:50
→ maniaque : 理由跟 cc101419 所提到的類似,若裝的是真電池 10/16 13:50
→ maniaque : 那電池有沒有可能在單純的撞測車體剛性時,產生意外? 10/16 13:51
→ maniaque : 汽油車只要不放汽油,就沒有任何可燃油氣可以被引燃 10/16 13:51
→ maniaque : 那飽電真電池當然不可能在測剛性時放在車子上 10/16 13:52
→ maniaque : 車用鋰電池不能0V狀態 (0V 過放電,電池就壞了) 10/16 13:55
→ maniaque : 這是撞車體 ,實驗狀況越單純越好,這是理科基本常識 10/16 13:55
針對Tesla 撞測時車子有沒有裝真正的電池這個疑問講一下
原本我也認為裝上測試用的等重假電池組是有可能的
但拿真正電池去撞也不是不可能
今天看到了CNET 的一篇介紹他們去參觀Tesla 撞測實驗室的報導
其中有一段講到：
First on the scene are a pair of engineers who will test the battery
integrity. The first holds the beefiest multimeter I've ever seen. The
second, standing just behind the first, wields a human-sized plastic hook.
It's the second person's job to pull the first away from the battery should
their rubber boots fail to insulate them.
簡單的說就是撞擊完成後會有兩位工程師先進入
第一位拿著萬用電表(記者用了他見過的最強大萬用電表形容)去測試電池完整性
第二位則是拿著跟人一樣大的塑膠鉤子預防他們的橡膠鞋絕緣不足導致第一位觸電
那他就可以把第一位工程師拉出來
等確定沒有漏電其他工程師才過來做他們該做的事情
所以這一段報導證實了Tesla 在做撞測時用的是有電的真正電池組
一個小細節，分享給大家看一下

另外報導中也提到拖動鋼纜是兩組Model S Performance 動力單元這件事
額外帶來的好處是在測試過程中可以精準控制扭矩、加速以及速度
在50 mph 測試時所測的的誤差只有0.023 mph
