Working Mechanism of E-vehicles

The smoke emitted from conventional automobiles contributes to more greenhouse gases. On the other hand, E-vehicles release very few greenhouse gases. E-vehicles have numerous advantages over fuel-based vehicles. In this article, you will understand the working mechanism of E-vehicles.

EVs are similar to automatic vehicles. They can move forward and backward. When you put the vehicle in gear and press the accelerator pedal, the following things occur:

  • The power for the electric motor is transformed from the DC battery to alternating current (AC).
  • The accelerator pedal transmits a signal to the controller, which changes the AC power frequency from the inverter to the motor to modify the vehicle’s speed.
  • A cog connects the motor and rotates the wheels.
  • When the brakes are applied or the car is decelerating, the motor converts to an alternator and generates power, which is then returned to the battery.

Basic Components of E-vehicles

Traction Battery Pack

The auxiliary battery in an electric drive vehicle provides electricity to power vehicle accessories.

Power Inverter

An inverter is a device that converts direct current (DC) power to alternating current (AC) power, which is used in electric vehicle motors. By adjusting the frequency of the alternating current, the inverter can change the speed at which the motor rotates. It can also change the amplitude of the signal to increase or decrease the power or torque of the motor.


The controller functions as a vehicle’s brain, managing all of its parameters. It regulates the charge rate based on data from the battery. It also translates accelerator pedal pressure to adjust the speed in the motor inverter.

Types of E-vehicles

  • Battery Electric Vehicle
  • Hybrid Electric vehicle
  • Fuel-cell electric vehicle

Benefits of E-vehicles

  • Electric vehicles have fewer moving parts than internal combustion vehicles, and they require less maintenance. Electric vehicles require less maintenance than conventional gasoline or diesel vehicles. As a result, the annual cost of operating an electric vehicle is significantly lower.
  • As there are no tailpipe emissions, driving an electric vehicle can help you reduce your carbon footprint. You can further reduce the environmental impact of charging your vehicle by using renewable energy for home electricity.
  • When easing off the accelerator, Electric vehicles have more smooth acceleration and regenerative braking. They have a lower center of gravity, which brings more ease and comfort.
  • The supply of fossil fuels is limited, and their use is wreaking havoc on our planet. Toxic emissions from gasoline and diesel vehicles have long-term negative effects on public health. Electric vehicles emit far fewer emissions than gasoline or diesel vehicles. From an efficiency standpoint, electric vehicles can convert approximately 60% of the electrical energy from the grid to power the wheels, whereas gasoline or diesel vehicles can only convert 17% -21% of the energy stored in the fuel to the wheels. That is a waste of approximately 80%. Although fully electric vehicles have no tailpipe emissions, even when electricity production is considered, petrol or diesel vehicles emit nearly three times as much carbon dioxide as the average EV.

Electric vehicles are continually evolving, and it is the best way to escape from constant fuel hikes and contribute to the environment.
