Comparison of differences and advantages between electric vehicles, hydrogen vehicles, and hybrid vehicles

Hello, I’m Kimrce who loves cars and animals. These days, there seem to be as many alternative fuel cars such as electric and hybrid cars on the road as internal combustion engine cars.



We’ve always talked about electric cars, but we’ve never talked about hydrogen cars or hybrid cars that emerge with electric cars. So this time, I’m going to summarize the difference between electric cars, hydrogen cars, and hybrid cars that you don’t know well.

As environmental problems arose, various kinds of cars such as electric cars, hydrogen cars, and hybrid cars came out naturally.



Accordingly, the Korea Automobile Research Institute predicts that domestic electric vehicles and hydrogen vehicles will account for about 50% by 2025. Let’s look at the difference between electric cars, hydrogen cars, and hybrid cars, which will account for a large portion in the future.

First of all, electric cars have moved away from conventional fossil-fueled internal combustion engines, as I posted last time. There is no engine and the high voltage battery replaces the role of the engine, generating electrical energy. It is also powered only by batteries and motors without an engine, so there is less noise and vibration.



It has a longer vehicle life than an internal combustion engine and costs less fuel than a gasoline car, making it an economical car. It’s easy to charge because you can charge it at home, and it’s easy to drive because you don’t need to change gears.

To sum up, the fuel of an electric car is ‘electric’, and it is characterized by supplying electric energy made from a high-voltage battery to the motor without an engine.



Hydrogen cars do not have engines, and they use hydrogen instead of diesel or gasoline, and the operation method is similar to that of internal combustion locomotives. Since hydrogen does not contain carbon sources, it can be recycled, and it is an eco-friendly car with only water emissions. Have you heard of the four radishes of hydrogen? Colorless, movie, odorless, and non-toxic are the four. The energy per unit mass is very large and can be regenerated by electrolysis of water.

The reason why it’s renewable is because of the principle of hydrogen cars. Hydrogen and oxygen in hydrogen chargers are supplied through fuel cells and divided into electrons and hydrogen ions.In the process, electrons are generated and transferred to an external circuit to be used as electrical energy.

Electrons become the power source for motors, and hydrogen ions react with oxygen to form water. The only emissions I mentioned earlier are the water produced like this.Therefore, unlike electric vehicles, the big difference between electric cars and hydrogen cars is that electricity is produced internally without receiving electricity from the outside. ​



To sum up, hydrogen cars don’t have engines like electric cars. Electric cars use ‘electricity’ as fuel, but hydrogen cars use ‘hydrogen’ as fuel. It’s possible to make electricity internally from hydrogen.

Lastly, I will explain about hybrid cars. Unlike electric and hydrogen cars without engines, hybrid cars have engines. Hybrid cars are characterized by having engines, electric motors, and large batteries.




It can also be driven by motor power when departing and driving at low speeds, reducing harmful gases and minimizing fuel consumption compared to internal combustion locomotives. In addition, various driving modes such as high speed, deceleration, slow speed, and acceleration are available for excellent driving performance. The battery is charged by converting energy generated during braking or deceleration into electrical energy using an electric motor.

To sum up the hybrid cars, they have engines and are used with electric motors to respond to the situation, making them more fuel efficient. It also creates energy internally, making it easy to charge the battery. Today, we talked about the characteristics and differences between electric cars, hydrogen cars, and hybrid cars. I hope it helps you understand each car.



The Korea Automobile Research Institute announced that the proportion of electric and hydrogen cars is expected to account for 80 percent in 2030. I’m looking forward to electric cars, hydrogen cars, and hybrid cars that will continue to develop in that time.

In the next session, we will find out the electric vehicle models represented by each automobile company, and continue to find out about the representative models of hydrogen cars and hybrid cars. I hope to see you again next time through posting and I hope you have a great day today!
