How does an Electric Vehicle Work?
Some of the earliest automobiles were powered by electric motors driven by batteries, but rapid advances to internal combustion engines quickly drove the heavier, range-limited EVs from the market. The pressing need to reduce air pollution together with new advanced batteries and motors have allowed EVs to reappear as a

What Are the Key Components of HEVs?
Essentially, an HEV combines an energy storage system, a power unit, and a vehicle propulsion system. The primary options for energy storage include batteries, ultracapacitors, and flywheels. Although batteries are by far the most common choice for energy storage, research is still being done in other energy storage areas.

Hybrid Electric Vehicles (HEV) What Are HEVs?
Hybrid electric vehicles (HEVs) combine the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle. As a result, HEVs can achieve twice the fuel economy of conventional vehicles. In combination, these attributes offer consumers the extended range and rapid refueling they expect

Hybrid-electric vehicles combine the benefits of gasoline engines and electric motors to provide improved fuel economy. The engine provides most of the vehicle's power, and the electric motor provides additional power when needed, such as for accelerating and passing. This allows a smaller, more-efficient engine to be used.

Retrofitting Engines Improves Air Quality
An estimated 160 million people live in nonattainment areas for ground-level ozone, also called smog, which is formed by nitrous oxides and other pollutants. About 65 million people live in areas that violate air quality standards for particulate matter. Reducing nonroad emissions is a critical part of the effort by

Hydrogen Or Hybrids?
DEAR DR. MOORE:
Which is better for the environment, hydrogen-powered cars or the new hybrids?
In the near term, I'd have to say the hybrids-because they offer a way to reduce pollution now.
