How Hybrid Cars Work and Their Fuel Efficiency

In recent years, hybrid cars have gained significant popularity in Indonesia. By combining two power sources, hybrid cars are much more efficient than conventional cars.

Beyond fuel-saving benefits, hybrid cars are more eco-friendly and support long-term sustainability.

So, how exactly do hybrid cars work to achieve such superior fuel efficiency? Here is a detailed explanation of the systems that power these vehicles.

What Is a Hybrid Car?

A hybrid car uses two main power sources: an internal combustion engine (ICE) and an electric motor powered by a battery. Conventional cars rely entirely on fuel. A hybrid system works with the driver to distribute power based on driving conditions.

Hybrid cars offer several benefits, including:

• Better fuel economy because the electric motor assists the fuel engine.
• Lower emissions, make it more eco-friendly.
• A quieter cabin because the car can run on the electric motor without engine noise.
• Improved energy efficiency through regenerative braking technology.
• A smoother driving experience because the power transfer between the electric motor and the gasoline engine occurs automatically.
  
  

Types of Hybrid Cars

Not all hybrids work the same way. Here are the categories based on how they function:

• Full Hybrid (HEV): The car can run solely on the electric motor at low speeds. The battery recharges automatically when you brake (regenerative braking).
• Mild Hybrid (MHEV): The electric motor assists the gas engine only at start-up or under heavy load. It cannot power the car on its own.
• Plug-in Hybrid (PHEV): It has a larger battery that can be charged using an external power outlet. This allows the car to travel longer distances using only electricity.

How Hybrid Cars Work

A hybrid car combines a gasoline engine and an electric motor. Here are the details:

1. Electric Motor Operates at Low Speeds

When the car starts moving or crawls through heavy traffic, the system automatically uses the electric motor as the primary driver. Since the gasoline engine is off, the vehicle consumes no fuel and produces no emissions.

2. A Gasoline Engine Provides Extra Power When Needed

When the car needs more power, such as during acceleration or at high speed, the gasoline engine turns on. It works best to provide the necessary boost to ensure it responds well.

3. Combination of Gasoline Engine and Electric Motor

In high-pressure situations, such as climbing hills or passing other vehicles, both the engine and the motor operate simultaneously. 

This combination delivers more torque without straining the gas engine, so you can enjoy better performance without worrying about fuel efficiency.

4. Regenerative Braking Charges the Battery

Standard cars waste energy as heat when they brake. Hybrids use something called "regenerative braking", which recaptures energy that would normally be wasted. 

When the driver hits the brakes or takes their foot off the accelerator, the electric motor runs in reverse. 

This makes it act like a generator, converting mechanical energy into electricity. This electricity is then stored in the battery.

5. Automatic Battery Charging

In addition to braking, the gasoline engine acts as a generator to charge the battery when energy levels run low. An intelligent onboard computer constantly monitors battery capacity and determines when the engine should charge it, so you never have to worry about finding a charging station.

Astra's Role in Driving the Hybrid Trend Nationwide

In Indonesia, the trend towards eco-friendly vehicles is growing rapidly. The government is encouraging the use of hybrids as a realistic transition step toward carbon neutrality.

The seriousness of the electrified vehicle market is reflected in Astra's involvement. As a major player in the national automotive industry, Astra is actively accelerating the adoption of green technology.
