Positives and negatives of electric cars: Full guide

Electric cars have made tremendous technological strides since their introduction, and they are more popular than ever.

However, some customers remain hesitant about the positives and negatives of electric cars and the transition from traditional gas-powered vehicles to electric ones, largely due to misconceptions that electric vehicles still suffer from the same shortcomings as in their earlier years. While electric cars do have their drawbacks, there are significant benefits to owning one.

How do electric cars work?

Electric cars operate in a completely different way than conventional gasoline cars. Here’s a simple explanation of how they work:

Battery:

The battery is the primary power source in an electric car. It acts like the fuel tank in a gasoline car.
The battery stores the electrical energy that will be used to power the electric motor.
Most electric cars use lithium-ion batteries, which have a high energy density and a relatively long lifespan.
The battery can be charged by connecting the car to an external power source, such as a home charging point or public charging station.

Electric Motor:

Instead of the internal combustion engine found in gasoline cars, electric cars use an electric motor.
The electric motor converts the electrical energy stored in the battery into kinetic energy that drives the wheels.
Electric motors have high torque, providing instant and smooth acceleration.
Electric motors don’t require a conventional transmission like gasoline cars, simplifying the propulsion system.

Electronic Control System:

A sophisticated electronic control system manages the flow of power between the battery and the electric motor.
This system controls the engine speed and torque, and therefore the vehicle’s speed and acceleration.
The electronic control system responds to driver inputs via the accelerator and brake pedals.

Regenerative Braking System:

Many electric vehicles are equipped with a regenerative braking system.
When the driver applies the brakes or takes their foot off the accelerator, the electric motor turns into a generator.
This generator converts the kinetic energy generated by the vehicle’s deceleration into electrical energy, which is fed back to charge the battery.
Regenerative braking helps increase the vehicle’s energy efficiency and range.

Simplified:

When an electric vehicle is started and the accelerator pedal is pressed, electrical energy is drawn from the battery and transferred to the electric motor, which converts it into motion to turn the wheels. When decelerating or braking, some of this kinetic energy can be recovered and returned to the battery.
