A hybrid vehicle is a fuel efficient vehicle having two motors- one a gasoline powered motor and the other electric motor. The reason for combining two motors is using their strengths and reducing deficiencies. Electric motor is used at low speed wile gas motors perform better at high speed generating extra power for a particular motor weight.
Benefits of Electric Vehicles Over Gasoline imagery December 13, In the past, electric cars were more of a joke than a practical solution. Even today, when most people think about an electric car they immediately remember the EV-1, a tiny little shoe box that could barely travel at freeway speeds and had a range of at most 70 miles.
However, the electric car has drastically changed since then. The Tesla Roadster is an all electric car, but get this: The two door convertible sports coupe can also reach a top speed of mph and has a range of miles.
It also comes with all the amenities of a normal car such as a navigation system, AC, radio, ABS Brakes, cruise control, and air bags. Now that sounds like a fun car to drive! Gasoline engines are very inefficient at extracting energy by burning gasoline and converting it into mechanical energy used to turn the wheels.
In comparison, an electric motor is very efficient, because so little heat is produced. As a result, there is no need for engine oil, coolant, or radiator.
The air alone is enough to keep the electric engine at an optimum operating temperature. In addition, when the vehicle comes to a stop or is stuck in stop and go traffic, the electric engine shuts off instead of remaining idle like a combustion engine.
Up until recently, batteries have been the biggest problem with electric vehicles. As a result, electric cars could only go about 70 miles before needing a recharge, which could take as long as 12 hours.
This was not something the public was interested in and so cars like the EV-1 faded away into obscurity. A few Eco-friendly people picked them up and claimed to love them, but even these first generation electric vehicles were expensive in relation to their gasoline competitors.
However, as of this writing, things have changed dramatically with the advent of lithium-ion batteries. The batteries are much smaller, much lighter, last considerably longer and have a much better recharge capability.
For example, the lithium-ion batteries in the Tesla Roadster Sports Coupe can be fully recharged in as little as 3. They are much lighter and the energy density is much greater.
This means the batteries take up less space compared to a lead-acid battery configuration of the same size and can last much longer. When an electric car needs to be recharged, you simply plug it into the wall at your house.
Currently, the Tesla Roadster can fully recharge in as little as three hours. Chances are your commute is around 50 miles a day which means you would need to recharge about once a week.
Most people who have never driven an electric car are startled when they come to a stop. Quiet is nice, but perhaps more so for those who live near busy streets or freeways as the sounds of passing cars will be greatly reduced.
So which is better? Electric cars are mechanically simple compared to the internal combustion engine. For example, here are some things a gasoline powered car has that an Electric car does not:Almost 34 million vehicles have been sold over the past two years in the US alone — and nearly all them run on gas.
Electric cars, meanwhile, have failed to launch. Electric cars are expected to need a replacement battery. Once the emissions from producing the second battery are added in, the total CO 2 from producing an electric car rises.
Disposal also doubles the emissions because of the energy consumed in recovering and recycling metals in the battery. Fuel costs for electric cars vs. gas-powered cars. You can directly compare electricity and gas costs when running an electric car vs.
a conventional gas-powered car with the vehicle maintenance costs can stack up over time.
With ICEs, engine maintenance can be a huge money sink, especially as cars age. Changing the engine oil, coolant. Pros of Electric Cars: Cons of Electric Cars: Energy efficient. According to the U.S. Department of Energy, electric vehicles typically convert 59%% of the electrical energy from the grid to power the wheels, compared to conventional gas vehicles, which typically convert 17%% of the energy stored in gasoline to power at the wheels.
Estimated damages for gas (left) and electric (right) cars by U.S. county; the damages range from roughly 1 to 5 cent(s) per mile on each side, green to red.
(Holland et al, , NBER). Electric cars cost less to recharge and save more money than gas cars based only on refueling. Studies show that electric cars need one third the amount of maintenance of a gas powered car.
