※ 引述《etrangere (outsiderOfTHEworld)》之銘言:
: 小妹最近在看電動車,想問一下發現的幾個問題,
: 1.普遍來說電車電車似乎有電池健康度衰退的問題,所以實際上是達不到估計里程的,想請
: 問這個是現在技術無法克服,在可見的3-5年也沒辦法改變,除了提高電池容量鋪更多電池
: 在車底才有辦法嗎? 續航力要靠更多電池才能補上?
衰退就衰退,只要衰退的量不多堪用就可以了
按照目前的實車數據在你開二三十萬公里換車之前的衰退大約在10%~20%
放更多電池續航就越好,問題是意義不大,徒增成本
很多沒用電車的經常認為他們每天都會開個幾百公里
但其實這種人很少
: 2.電動車的充電速度是出廠後可以透過軟體的更新加快速度嗎?還是就受限於硬體?
受限硬體
所謂什麼軟體更新功能更強了都只是把原本鎖住的限制解除
: 3.電車看起來更像科技產品,會不會有過了一兩年電池技術發展更好,或是其他硬體可以更
: 省電,導致兩年後二手車價暴跌的問題呢?
: (有點像大改款兩年前的車少了幾顆安全氣囊,價值降低的狀況)
你可以看一下目前舊電池的model 3有沒有車價暴跌
當然如果明年突然出現一個車廠的新車續航2000公里價格還一樣性能也好
那之前的電池就會暴跌了,只是電池技術很難這樣突然飛天
: 4.在低速塞車的狀況下30-60km/hr,比較耗電還是高速穩定(120km/hr)比較耗電呢?(還是
: 這要看每個車款不一樣?? 有無大大可以提供i4的數據?)
要把冷氣時間加進去,這中間有無數可能沒有一定答案
汽油車內燃機甜蜜點高高速比較省油
電動車反而低速省電因為高速要對抗風阻
但開的慢冷氣耗電占比就會變高
: 目前有興趣的車是bmw edrive40
: 但是看了國外的實測大概里程是500公里左右,台灣國道蠻容易塞車就塞個1小時,有點擔心
: 相比油車,馬三或是中型房車5系列都至少可以開550甚至650公里以上再加油
: 很喜歡i4啊,但很擔心電池健康度的問題
: 要補充一下,大概一個月會有一次到兩次台北開到墾丁的距離,
: 所以才會對電池續航力比較有疑慮一點,解法是不是就固定找個中間點充電?
要充電啊,而且你人也要休息啊,台北到墾丁就算全程不塞車也要4~5個小時何況有堵
就算是職業駕駛,每開車四個小時都規定要休息30分鐘
我也不知道為什麼很多人每天都開六七八個小時都不休息,蠻危險的
