電動車採單踏板運行的設置好嗎?Porsche:「我覺得不行」
其實這類功能在部分hybrid車款中也同樣擁有,畢竟主要目的相同,但最近卻有車廠對這
項功能表示不同意見。旗下電動車Taycan在全球賣得嚇嚇叫的德國車廠Porsche表示,若
想讓電動汽車盡可能的行駛較遠里程,最好的方法其實是增加滑行的機會。
車輛在滑行時,若電機系統不介入其過程,就能讓汽車在幾乎不消耗能量的狀態下移動,
並且相對自然。Porsche工程中心底盤測試資深經理Martin Reichenecker針對此議題表示
,讓車輛持續滑行可以保持車輛動能,是擁有最佳效率的行駛方式。「單踏板駕駛模式在
運作時,啟動瞬間還是會花費能源驅策啟動,而後再將回收的能源轉化為動力,在整個過
程中其實啟動了兩次能源消耗。」目前包括Taycan、以及明年將上市的Macan EV,皆未採
用單踏板模式運作。
雖說如此,Porsche表示煞車動能回收仍是Taycan的電源管理主要項目,該廠指出約莫有
90%的日常煞車行為,可以單靠發電機的回充系統完成,若電機系統的減速能力不夠,傳
統卡鉗煞車會在時速5km/h內的範圍輔助作動。
當然若是駕駛Taycan Turbo S在賽道上奔馳時,就需要傳統煞車全力支援,此時Taycan可
以在大腳煞車2秒鐘的時間中,回充最高290kW的能量,可提供0.7公里的行駛里程。另一
方面,煞車動能回充系統讓傳統煞車的來令片得以使用非常長的時間而不需更換。
--------------------------------------------------------------------
若是能滑行到煞停,那的確是續航最大化的最佳解
但實際駕駛很難,因為突發路況需要煞車減速的情況太多了
不過Taycan的回充效能和減速力道其實很不錯,但不是放掉電門就回充,而是踩下煞車時
啟用,目的是盡量讓車輛能在滑行狀態
單踏板模式優點還是在於輕鬆方便,而且減輕腳酸壓力
