看火力發電廠就知道了
火力發電廠 熱效率大概40%~43%之間
這大概就是極限了
油電混合的熱效率大概33%~35%
很接近火力發電廠的效率了
而且油電混合的車
因為發電機線路傳遞到電池的距離短
所以阻抗小很多
一般電車因為發電廠到充電站在到電車身上
傳遞傳遞再傳遞
耗損大約90%
43*0.9=38.7
效率大概38.7%
跟油電混合差不到哪去
純油車
目前25%~27%效率就是極限了
火力發電廠的效率也是效率越來越高
以前只有35% 現在火力發電廠43%
燃燒效率上限看看火力發電廠的就知道
要再突破我覺得很難了
※ 引述《cake51640 (uuuu4ni)》之銘言:
: 嗨嗨
: 在電車陸續搶佔市場的年代
: 一堆車子改成電車或油電車
: 剛好在想
: 今天純油車的油耗
: 還有可能往上升嗎
: 之前聽說豐田引擎的熱效率很高
: 還有辦法更高嗎
: 有沒有動力學大師
