Cars - Essay Example

Gasoline has a much higher energy density than batteries do. For example, it takes about 1,000 pounds of batteries to store as much energy as 1 gallon or 7 pounds of gasoline.
As fuel tank is the energy storage device for gasoline engine, the batteries in a hybrid car are the energy storage device for the electric motor. Gasoline in the fuel tank can only power the gasoline engine but the electric motor on a hybrid car can put energy into the batteries as well as take energy from them.
The role of transmissions on hybrid cars is same as the transmissions on conventional cars. Some hybrids have conventional transmissions, like the Honda Insight. Other hybrids have different ones, like the Toyota Prius.
The simplest forms of self-propelled motorized transportation are electric cars. Its driving mechanism or engine is made up of a succession of batteries attached to an on and off switch that in turn is attached to an electrically operated motor.
The wheels are driven by the electric motor, which thereby propel the car into motion. Generally the amount of energy is controlled by a complicated technique that goes into the motor and the gear system and further helps the wheels in a more capable manner. Some electric cars also have solar collectors that convert solar energy into electricity for slow recharge of the batteries.

Here question arises: why should you bother with an electric car There are several reasons as its answer. Electric cars offer a curious driving experience with exceptional control as well as quick initial acceleration thanks to their low center of gravity. Even at lower speeds, it's almost continuous torque makes it easy to climb curbs, sharp turns and steep inclines. Further, the fuel cost is increasing regularly; therefore, use of electrically charged cars is an ideal choice.
A simple electric car can be built in just two weeks. It is so fascinating and easy. Electric cars can even be built by anyone because these cars are very simple in overall structure. The main components are a simple frame, an electric motor, a car battery, basic wheels and an electric on and off switch. Although, the task requires some extra efforts as well but it becomes quite easy especially for those have a simple blue print, knowledge of electric currents and wiring and the parts to assemble them all together.

The size class for trucks is defined by the gross vehicle weight rating (GVWR), which is the weight of the vehicle and its carrying capacity. Fuel economy regulations do not apply to heavy-duty vehicles, so they are not tested.

Summary

The electric motor on a hybrid acts as a motor as well as a generator. It is very complex motor. For example, when it needs to, it can take energy from the batteries to accelerate the car as well as it can act as a generator to slow the car down and put the energy back into the batteries.
