混合动力型汽车

利用两种或两种以上能源的汽车称为混合动力型汽车，通常指的是利用汽油和电池的汽车．该类型汽车，一般有一台质量较小且较为经济的汽油发动机与电动机．汽油发动机可以满足大多数情况下行驶的需要，当需要更多的动力时，可以再由电动机提供，电动机由能重复充电的蓄电池供电．

有一种类型的混合动力型汽车，称为“并联混合动力型汽车”（如图）．该车的汽油发动机和电动机通过同一个变速器与车轮相连．何时使用汽油发动机，何时使用电动机，何时两者同时使用由内置电脑确定．这类汽车除了油箱里的汽油之外，不再需要外界其它能与电动汽车不同，你不需要将混合动力型汽车的蓄电池接到电源插座上去充电．普通汽车在制动时，汽车的动能全部转化为内能．该类型汽车在制动时，电动机作为发电机使用，把汽车的一部分动能转化为电能，实现了对电池的充电．
