how the hybrids work
Jun. 10th, 2008 08:29 amHybrid Cars: How They Work | LiveScience:
The basic problem with automobile gasoline engines is that, to let you blithely roar down the highway, they have to be designed for peak power demands. So, for crawling around the city, they're grossly inefficient. (For waiting at red lights, they are infinitely inefficient.)The is followed by details on the three styles, well worth reading before you go shopping...
In response, hybrids use a battery-powered electric motor in low-power situations, and a gas engine in high-power situations, switching back and forth automatically. The gas engine is simply switched off at red lights, and is often designed to operate in a narrow power range when it is switched on, making it more efficient. The battery is recharged by the gas engine. Generators attached to the brakes can also turn some of the braking momentum (normally lost as heat) into electricity for battery charging.
Of course, in the real world things are more complicated, and in the one we inhabit, hybrids fall into three classifications: full-court full hybrids, half-court mild hybrids and the plug-ins.
