8 Components of Electric Car Engine

Curious, what are the components in an electric car engine ? Technology is growing rapidly and brings many changes in various fields. The automotive sector is no exception, which continues to increase in almost all sectors.

Not only adding new technology, this development also brings automotive manufacturers to produce new innovations, for example the innovation of making electric cars or cars that do not have a combustion system.

Changing the position of the combustion engine with a traction motor or electric car engine powered by a battery as the main power source. This is what makes the electric car engine an environmentally friendly automotive change.

Hyundai, Releases More Eco-Friendly Electric Car

Several well-known car manufacturers have produced and released electric cars to reduce carbon emissions in Indonesia. One of them is Hyundai, where a dashing look and design is found in almost all Hyundai electric cars.

This time we will not discuss the type or brand of car. Instead, we will share a little information about electric car engine components, which may be many people don't know about.

Electric Car Engine Components

When it comes to electric car engine components, basically every type of electric car has different components. However, there are some key components in an electric car engine that are always present. Here are 8 components of an electric car engine, including:

1. Traction Battery Pack

The main function of the battery in an electric car engine is as an energy storage system in the form of direct-current (DC) electricity. If it gets a signal from the controller, the battery will supply direct current electricity to the inverter which will be used to drive the motor.

The batteries used in electric car engines are rechargeable batteries, which are arranged in such a way as to form a traction battery pack.

Traction batteries for electric car engines are of various types. The type of lithium-ion battery is the most widely used type. Charging the battery is done with a charger that is part of the car system (on-board charger) or with an external charger (off-board charger).

2. Power Inverter or Power Inverter

The inverter is an electric car engine component whose function is as a converter or converter of direct current (DC) in the battery to become alternating current (AC) which then this alternating current will be used by the traction motor.

Not only that, the inverter is also used to convert AC current into DC current during regenerative braking for recharging or charging batteries. The inverter that is usually installed in some electric cars is a type of bi-directional inverter.

3. Controller

The main function of the controller or controller is as an element of the electric car engine component that regulates the energy in the battery and the inverter is then channeled to the traction motor.

The controller gets the main input from the car pedal which is set by the driver. The pedal setting will determine the variation of the input voltage to the motor and determine the speed of the car.

This electric car engine component regulates the flow of electricity generated by the traction battery and controls the speed of output torque and traction.

4. Traction motor

The controller provides power from the traction battery, then the traction motor will work to turn the wheels and transmission. Some hybrid cars use a type of motor generator that performs the function of regeneration and propulsion.

The BLDC type traction motor or brusless DC traction motor is the most dominant applied. BEV cars use this electric car engine component to replace the ICE (Internal Combustion Engine) function.

Some electric car manufacturers use permanent magnet motors, while others use three-phase induction.

5. Chargers

The component of an electric car that supports is the charger. This component is not really mandatory in every electric car. This is because some types of electric cars do not require a charger to charge the car.

The way the charger works is to charge the battery with AC electric current and then convert it to DC current which is stored in the traction battery.

There are 2 types of chargers in electric cars. First , the on-board charger that is attached to the interior of the car. Second, off board charger which is outside the car.

6. Auxiliary Battery

Electric cars usually have more than one battery in addition to electric power in the form of an auxiliary battery.

This component is used for storage and a provider of electric current to turn on car accessories that are not the main component. For example AC (Air Conditioner), alarms, wipers, car lights and others.

Not only that, the auxiliary battery can also be used as a backup battery if at any time the traction battery gets into trouble.

7. DC Converter

DC current is obtained from the traction battery which is high voltage so it requires a DC converter to convert it into low voltage electric current.

The goal is that electricity can be used by other electric car components that require low-voltage electricity. A DC converter is also a tool to charge the battery.

8. Thermal System

If you drive an electric car, the temperature in the electric car engine becomes hot. This is the role of the thermal system, which is used as an electric car engine coolant.

Its function also includes maintaining the temperature of the traction motor and other electrical components. That way, the car's components remain at normal temperatures even though the electric car is driving fast for a long time.

Those were the 8 components of an electric car engine and their explanation. Hopefully the above information can be useful for those of you who are looking to have an electric car. One of the electric cars that can be an option is the Hyundai electric car, which has proven quality and supports carbon emission reduction programs in Indonesia.
