    - No, motor cann't be the final drive. 混合车becomes 汽油车 in your experiment - PhonyDoctorPhD (489 bytes) 2005-10-13, 19:42:16
- Let me WenKe tell you what affects the "effeciency" - skipper3 (1005 bytes) 2005-10-13, 17:09:21
- electric motor's efficiency, defined it, 1st, please. - 无知 (0 bytes) 2005-10-13, 16:39:34
  - Efficiency = Output Work(energy)/Input Work(energy) - HunHunSheng (145 bytes) 2005-10-13, 16:43:53
    - then what make you think slow moving e motor is more effiecient? - 无知 (0 bytes) 2005-10-13, 16:54:15
      - It is well established fact and I believe enginners already tested it - HunHunSheng (4 bytes) 2005-10-13, 16:58:19

        read this, it seem low output power has low effeciency. - 无知 (83 bytes) 2005-10-13, 17:21:57
        
        再看这个，基本是满负荷效率高。低速不满负荷嘛。哈哈。 - 无知 (43 bytes) 2005-10-13, 17:30:01
        
        只要在低速时电动机比内燃机效率高就可以解释 - HunHunSheng (164 bytes) 2005-10-13, 18:14:29

For a person, walking is much more energy-efficient than running - HunHunSheng (201 bytes) 2005-10-13, 15:31:15
Wind resistance is very strong on highways - HunHunSheng (146 bytes) 2005-10-13, 15:29:11
- true wind resistance is a possible factor - 4U4luC2 (164 bytes) 2005-10-13, 15:40:52
  - Then maybe it is due to electrict motor's high efficiency at low speed - HunHunSheng (233 bytes) 2005-10-13, 15:45:41
混合车的电力引擎只在低速下启动。高速路上用cruise还是烧的汽油。 - 虎子 (0 bytes) 2005-10-13, 14:51:53
- 不烧汽油电力引擎用的电从哪里来？ - 4U4luC2 (0 bytes) 2005-10-13, 14:59:52
  - 电池的电力来源挺多。可以参考这个网站 - 虎子 (239 bytes) 2005-10-13, 16:04:07
    - Unless you drive from a high place to a low place - HunHunSheng (182 bytes) 2005-10-13, 16:09:19
      - true. the "multiple sources" of energy originally come from gas, too - 虎子 (0 bytes) 2005-10-13, 16:13:37
  - 有时候只开3/6气缸造成？ - 无知 (0 bytes) 2005-10-13, 15:01:57
    - 你是指市内开只开3缸？那巡航时不也可以关掉3缸吗？ - 4U4luC2 (0 bytes) 2005-10-13, 15:06:32
      - here is the toyota answer (not accord 3/6) - 无知 (5418 bytes) 2005-10-13, 15:11:07
        
        解释可能是EPA使用满容电池城市高速各只测了一缸油，换句话说偷电犯规 - 4U4luC2 (0 bytes) 2005-10-13, 15:24:32
        
        Prius system relies more on the batteries in the city than on the highway? - 4U4luC2 (86 bytes) 2005-10-13, 15:16:58
        
        In high way, you have to use gas engine - HunHunSheng (201 bytes) 2005-10-13, 15:27:06
会不会是在高速路上发电功率超过蓄电池能力所以浪费了？ - 乱劈材 (0 bytes) 2005-10-13, 14:35:17
- 电是用多少发多少，发多少用多少,平衡的。不要”乱劈“ hehe.. - catfish (17 bytes) 2005-10-13, 15:35:47
- Then it's a design flaw - 4U4luC2 (0 bytes) 2005-10-13, 14:57:52
