ELECTRIC CAR COMPONENTS AND FUNCTIONS

Hello automotive friends. On this occasion, we will discuss the components of an electric car and its functions. Lately, with the emergence of Tesla cars that carry electric cars, electricity is in great demand. Therefore we will review it in more detail.

Electric car

The main components of an electric car, their functions and how they work are as follows.

When the car pedal is pressed, the controller will take and regulate electricity from the battery and inverter. With the setting controller, the inverter then sends a certain amount of electricity to the motor (according to the depth of pressure on the pedal). The electric motor converts electrical energy into mechanical energy. The rotation of the rotor in the traction motor rotates the transmission, the wheels rotate and the car moves.

The basic components of an electric car

Traction Battery Pack or traction battery

This component has a function, namely as an energy storage system in the form of direct current electricity. If you get a signal from the controller, a shout sends DC electricity to the inverter which is used to drive the motor. Traction batteries in electric cars can vary. This type of lithium-ion battery is becoming the most widely used in electric cars. Charging the battery is carried out by a charger that is part of the car system (on board charger) or by an external charger (off board charger).

Power inverter or power inverter

This one component has a function as a component of converting direct current from the battery into AC alternating current, then this alternating current is used by the traction motor. This component also functions to convert the AC current during regenerative braking into DC current for later use to charge the battery.

Controller

This one component has a main function, namely as an energy regulating component element in the battery and inverter which is then distributed to the traction motor. This component gets the main input from the car pedal. This pedal setting will determine the frequency variation or voltage variation entering the motor, as well as determine the speed of the car.

Traction motor

This component in an electric car will work to rotate the transmission and wheels. Some hybrid cars use a type of motor generator that has a function as a driving force and regeneration. The bldc traction motor is the most dominant to be applied.

Charger

The charger in an electric car has a function as a component of the battery charging equipment. Chargers work to convert AC electricity into DC and then stored in the battery. There are two types of chargers in cars, namely

On board charger, the charger is located and installed in the car

Off Board charger is not in or not installed with the car.

A car using an onboard charger will receive AC alternating current, while a car with an off-board charger type will get direct current as its reference point.

Transmission

This one component functions to transfer mechanical power from the electric traction motor to move the wheels.

DC / DC converter

This component in an electric car has the function of changing the higher voltage DC electric power from the traction battery package to a lower voltage. This component is needed to run car accessories and also recharge additional batteries.

Auxiliary battery

This one component on an electric motorbike has a function to provide power for car accessories, such as wipers, alarms, and others.

Thermal cooling system

This component has the function of maintaining a suitable operating temperature range for engines, power electronics, traction motors, and other components.

Charge port

This component in an electric car has a function as a charging point that allows the vehicle to be connected to an external power to charge the car battery. Hybrid cars and FCEV do not have to charge so they do not allow recharging by external sources.

This is the article we can present about the components of an electric car. Hopefully, this article can add insight to the automotive world friends.
