Electric Vehicles

Introduction

The demand needs to know the upbringing challenge to gain the advantage on new vehicle technologies, and in the process, substantial economic development benefits. In a world where oil is the limited resource, an alternate source of transportation fuel i.e. electricity is not only a smart investment, but as some would say, it is an inevitable one. Further, the switch to electric vehicles will generate demand for existing jobs and create new jobs as well. As study after study confirms, job growth in automobile industries will outweigh any reduction of jobs in traditional fuel industries, resulting in net job growth. Electric vehicles create additional economic development opportunities by improving quality of life, reducing energy spending, and decreasing reliance on foreign oil.

The importance of electric vehicle like any transformative new technology, creates a variety of potent economic development, challenges and opportunities. While the electric vehicle market is still at a relatively early stage of development, it is poised to reshape industries and communities the world over. This section provides a quick overview of the potential benefits of electric vehicles so that economic developers can better assess what the evolution of this market will mean to their specific local communities.

Description of an Electric Vehicle.

The electric vehicle (EV) is propelled by an electric motor, powered by rechargeable battery packs, rather than a gasoline engine. From the outside, the vehicle does not appear to be electric. In most cases, electric cars are created by converting a gasoline-powered car. Often, the only thing that clues the vehicle is electric is the fact that it is nearly silent. Under the hood, the electric car has: an electric motor, a controller, and rechargeable battery.

Transmission of power flows from mechanical paddle to motor drive. It uses a battery pack (batteries) to provide power for the electric motor..Four main parts make up the electric vehicle: the potentiometer, batteries, direct current (DC) controller, and motor.

A controller takes power from the batteries and delivers it to the motor. The controller can deliver zero power (when the car is stopped), full power (when the driver floors the accelerator pedal), or any power level in between. The battery pack connected in series to create a voltage level of 144v, The controller reads the setting of the accelerator pedal from the two potentiometers and regulates the power accordingly. If the accelerator pedal is 25 percent of the way down, the controller pulses the power so it is on 25 percent of the time and off 75 percent of the time. If the signals of both potentiometers are not equal, the controller will not operate the motor.

Summary  

As it is evident, the electric vehicle has many advantages and benefits over the internal combustion engine and hybrid vehicle. It is cleaner and much more efficient; however, it also has disadvantages. It is heavier, limited to the distance it can travel before recharge, and costs more. The future of the EV relies on its battery. If researchers can produce or find the “super battery”, the EV’s future is promising. As of today, each vehicle has its own characteristic that makes it better than the other. Only time and technological improvements will tell which vehicle will excel in the future.
