EV electric vehicles are becoming one of the important trends in the auto industry. However, the concept of what is an EV car?, their uses and special features are still not known to many people. So let's start our journey to explore the world of EV electric vehicles Wuling EV Vietnam in this article!
1. What is an EV?
EVs, also known as Electric Vehicles, are cars equipped with engines that use 100% electric energy. A special feature of EV cars is the ability to operate with an electric motor instead of an internal combustion engine (gasoline, diesel) like conventional cars. Therefore, they can create rhythmic movements without producing carbon emissions or any noise.
What is the concept of an EV vehicle and the history of this special vehicle line?
The idea of the first EV car was born in 1828. After 4 years of development, the first EV car has been put into use. It can accommodate 6 passengers and can travel up to 22.5 km/h. After decades, EV cars are still constantly being researched and developed. However, this idea came to a standstill in the 1990s because the battery's ability to store electricity was too weak. Soon after, the birth of Sony's Li-ion and Lithium-ion battery lines in 1991 helped revive the idea of EVs. Gradually, EV cars have become a growing trend in the auto industry.
Currently, EV electric cars account for only 1% of the global auto market. However, with many outstanding advantages and increased human awareness, the trend of using EVs has increased dramatically. Many developed countries such as France, Norway, Sweden, etc. have set the goal of banning the use of traditional cars by 2040. In Vietnam, the Government is also making efforts to introduce price subsidy policies for EV car lines aimed to promote investment and production of electric motors.
2. Structure of EV electric cars
Line structure what is an EV car? Basically, EV vehicles include main components: vehicle battery system, power electronics system, electric motor, transmission coordination, energy recovery brake and electric charging station.
2.1. Vehicle battery system
The battery system is the most important part in the structure of a large EV vehicle. This system is installed right under the vehicle floor, containing electrical energy to supply the engine and other electronic devices.
EV vehicle battery system
Currently, EV vehicles use lithium-ion battery technology, a battery type that can be recharged many times while still maintaining high performance. The battery of an EV car usually has a voltage of 400V, quite modest compared to a conventional fuel tank. This is a big technical challenge that makes this vehicle still have many limitations compared to other cars transmit system. Charging time will also be longer than refueling time. Furthermore, the cost of the battery also accounts for 1/3 of the cost of the EV car.
2.2. Power electronic system
What is an EV car's power electronics system? Power electronics is a system that helps convert electrical current for the motor to operate. This is an indispensable part for any EV vehicle.

2.3. Charging station
What is an EV car's charging station? This infrastructure is extremely important for electric vehicles, it is the place to transform the flowyes into energy to charge the battery. With increasingly improved technology, EV cars can be quickly charged in just 3 minutes, with a distance of up to 100 km.
Charging stations for EV vehicles are increasingly improving
2.4. Electric motor
Electric car engines will not use fuels such as gasoline or oil to produce energy. Instead, it uses electricity from hThe system stores electricity (usually a battery) so it can operate. Types of electric motors commonly used today include 3-phase synchronous motors and 3-phase asynchronous motors.
Find out what is the electric motor of an EV vehicle?
Electric motors often have higher efficiency, so operates smoothly more favorable than the internal combustion engine. Electric engines also do not produce harmful emissions like diesel engines. With improved technology levels, electric motors today have an efficiency of up to 90%. This is an extremely impressive number, far superior to the operating efficiency of internal combustion engines, which is only about 30% to 40%.
2.5. Drive coordination
The transmission system of an EV electric car is a combination of engine, transmission and other transmission components. This system plays a role in determining the vehicle's range and performance.
Drive coordination system of EV electric cars
Each EV car is equipped with 4 separate electric motors for each wheel. Therefore, an AI (artificial intelligence) system is needed that automatically coordinates the transmission into uniformity when the vehicle moves. This system will ensure optimal balance and power when the vehicle moves.
2.6. Energy recovery braking
Energy recovery braking, also known as regenerative braking, recovers energy when the vehicle is braked and uses it to charge the battery. In addition, the car is also equipped with a multi-function charger. This part allows the vehicle to integrate energy from all power sources such as 220V electricity, electricity from 10kW, 22kW or 43kW charging pins.

3. Advantages and disadvantages of EV cars
EV electric vehicles are gradually becoming a new development trend, to be attractive choice for future mobility. Understanding what is an EV car's the advantages and disadvantage are very important.
3.1. Advantages
EV vehicles are gradually becoming a popular choice in the auto industry with many notable advantages:
- Superior performance, capable of very fast acceleration in just a short time.
- EV electric vehicles are often equipped with smart technology such as AI built into the system.
- Electric vehicles are equipped with many maximum safety features.
- With increasingly optimized production processes, EV electric vehicle prices are often cheaper than internal combustion engine vehicles.
- Electric vehicles are an environmentally safe choice, do not produce harmful emissions, and do not use fossil resources.
- With a simple vehicle structure, EV vehicle maintenance and repair become more convenient.
- More and more electric charging stations are being built to serve people's increasing demand for using EVs.

3.2. Limits
Besides the outstanding advantages, EV electric cars also face certain limitations.
- Currently, some features of electric vehicles are still in the testing phase and need a lot of time to perfect.
- Besides, the process of charging the battery of an electric vehicle also takes a lot of time. Although experts are working hard to develop fast charging technology, the operating time of EV vehicles is still limited term compared to traditional vehicles.
EV cars still have some limitations
4. Compare EV and EV electric vehicles FCV
The difference between FCV and what is an EV? This question will be answered through the table below.
