What are the Primary Components of an Electric Car?


Electric powered cars are becoming popular in the present time because of the ever-increasing fuel problems. In fact, there are about 250,000 electric hybrid vehicles being sold every year since 2007. With this, electric charging stations are now found throughout the United States.

Electric cars are known to be very efficient and they consume less energy making them environmentally friendly automobiles. To ensure efficient operation and prolonged life of electric vehicle batteries, you can utilize the services of battery thermal management system company that specializes in designing and manufacturing advanced thermal management systems.  But have you ever wondered what the components of an electric powered car’s engine are, and how they work?

What are the Primary Components of an Electric Car?

Primary Components of an Electric Car

An electric powered car has three primary components. These are the electric engine, motor controller, and battery.


The battery of an electric car can be charged through the use of ordinary grid electricity at a specialized power station. But aside from the conventional lithium-ion battery technologies, there are also other major battery technologies which can be used for electric cars.

  • Lithium-Ion Batteries: This battery technology gives extra performance and range. However, it also carries the highest price tag. Lithium-ion batteries are lighter than Lead acid and Nickel metal. These are also the batteries used in digital cameras and smartphones.
  • Lead Acid Batteries: This battery technology is the most popular. It is also the cheapest among the battery technologies. What’s good about it is it’s 97% recyclable.
  • Nickel Metal Hydride Batteries: This battery technology provides higher output and better performance but it costs much more than lead-acid batteries.

Motor Controller

The motor controller of an electric car administers its complete operation and the distribution of its power at any given moment. It acts as a floodgate between the motor and batteries. It helps monitor and regulates all key performance indications such as the vehicle’s operator, motor, battery, and accelerator pedal. It has a microprocessor which can limit or redirect current. It is used to either improve the mechanical performance of the car or suit the operator’s driving style. There are also more refined controllers which are capable of greater accuracy and thus, higher efficiency.

Electric Engine

Unlike a gasoline engine with lots of moving parts, an electric engine or motor only has one moving part. This makes it a very reliable source of motive power. Choosing an electric engine depends on your car’s system voltage. They can be structured to use either AC or DC current. AC motors are less expensive and lighter compared to DC engines. They are also more common and they tend to suffer from less mechanical wear and tear. However, AC technology requires a more refined or sophisticated motor controller.

Other Components of an Electric Car

Aside from the three primary components of an electric car, it is also made up of other components which are important as well. These are the regenerative braking and the drive system.

  • Regenerative Braking

As the electric car moves, the electric motor generates a forward momentum and it can be used to charge the batteries when you apply the brakes, which is commonly referred to as regenerative braking. It can recover up to about fifteen percent of used energy for acceleration. Though this component is indeed effective, it cannot generate enough to fully recharge an electric car.

  • Drive System

The function of the drive system is to transfer mechanical energy to the traction wheels, generating motion. An electric car does not require a conventional transmission. However, it has several internal configurations depending on the components in use. For example, there are some designs which use multiple smaller motors that power each wheel individually. Large electric motors, on the other hand, may be coupled to the rear wheels using a differential housing.

The components of an electric powered car are much simpler compared to the components of a gasoline-powered car engine. However, electric cars cannot go as fast as gasoline-powered cars can. Electric vehicles, on the other hand, can reduce energy consumption in different ways like automatically turning the engine off when the car is idle.

Different Types of Electric Cars and How They Work

Electric vehicles come in three types and they are classed by the degree that electricity is used as their energy source.

Battery Electric Vehicles or BEV

This type is fully electric with rechargeable batteries and does not have a gasoline engine. It stores electricity onboard with high-capacity battery packs. Battery power is used to run the electric motor of the vehicle and as well as all onboard electronics. Battery electric vehicles do not emit harmful emissions and hazards, unlike traditional gasoline-powered vehicles. They are charged with electricity from an external source.

Plug-In Hybrid Electric Vehicles or PHEV

This type of electric vehicle is also known as Extended-Range Electric Vehicles and it is powered by both petrol and electricity. Its battery can be recharged through both regenerative braking and “plugging in” to an external source of electrical power. You will need to install one Home car charging point for charging this car. This type of electric car can go anywhere from 10 to 40 miles before its gas engine provides assistance, unlike standard hybrids which can only go about 1 to 2 miles before the gasoline engine turns on.

Hybrid Electric Vehicles or HEV

This type of electric car is also powered by both petrol and electricity. Its electric energy is generated by its own braking system to recharge the battery. That process is called “regenerative braking”. In that process, the electric motor helps to slow the vehicle and uses some of the energy normally converted to heat by the brakes. It starts off using the electric motor and then the gasoline cuts in as load or speed arises. The two motors of a hybrid electric vehicle are controlled by an internal computer, ensuring the best economy for the driving conditions.

The Top Electric and Hybrid Cars in the Market

Here are some of the many electric and hybrid cars you can find in the market today.
