Components of an Electric Car and Their Functions

Components of an Electric Car and Their Functions — To reduce the effects of worsen global warming, nowadays many people have started to use electric cars. As the name suggests, this type of vehicle uses electricity as a source of energy so as to minimize the effects of pollution. But do you know what the components of an electric car are?

It is undeniable that increasingly sophisticated technological developments have brought many changes, including in the automotive industry. One proof is the presence of electric cars that are not only equipped with advanced features, but also use technology that is claimed to be more environmentally friendly because it does not produce vehicle emissions.

Many car manufacturers have then issued their flagship electric car products, one of which is the Wuling GSEV which is equipped with the latest technology. This electric car can be a vehicle of the future that is safer and more environmentally friendly.

Each type of electric car is usually equipped with its own advanced features. It’s just that in general, the electrical components in this type of car more or less use the same main components.

This time we will discuss what the main components are in an electric car so that we can better understand how it works

Components of an Electric Car and Their Functions

Traction Battery Pack

The first component available in every electric car is a traction battery pack. The main function of this component is to store and supply direct current (DC) to the inverter. Furthermore, the power generated will be used to drive the traction motor. When the controller sends a signal, the traction battery will immediately work by transferring electric current to drive the traction motor. This electric car component is made with a sturdy structure so the components are not easily damaged. Not only that, the traction battery is also designed to be recharged many times.

Power Inverter or Power Inverter
Inverter is a component that functions to convert DC current into AC current or alternating current. The resulting current will then be used to drive or rotate the traction motor. This component is one part of the main driving component of an electric car.

Not only that, this component also functions to convert AC current during regenerative braking so that it becomes DC current which can then be used to recharge the battery. For electric car battery components, the type of inverter used is usually a bi-directional inverter type.


This electric car component functions as a regulator of energy or electrical power in the battery pack to the inverter so that it can drive the traction motor. The way the controller works is to send a signal from the electric car pedal which is stepped on by the driver so that it affects the speed of the vehicle.

Traction Motor

Traction motor is an electric car component in the form of an electric dynamo. This component functions to drive the transmission and wheels so it is called one of the most important components in supporting the electrical performance you use.

You need to know that the traction motor can rotate up to 18,000 rpm. Meanwhile, the type of traction motor that is most widely used in electric cars is the Brushless DC Traction Motor (BLDC). However, for the BEV type electric car, it uses a traction motor of the Internal Combustion Engine (ICE) type.


The charger is a supporting component as well as a complement in an electric car. The main function of this component is as a tool to recharge the battery pack in electric cars. The way the charger works is to use AC PLN electricity and then convert it to DC electricity so that it can be stored in an electric car battery pack. There are several types of electric car charger tips that are usually used, namely On-board chargers and Off-board chargers.
