Ô tô điện – Cấu trúc và hoạt động như thế nào?

The main components of electric vehicles:

A: Battery: Combined from many small battery cells. Between the battery cells there is a cooling system.

B: Inverter: The system converts direct current from the battery into alternating current for the motor. And vice versa turns alternating current from the motor into direct current to reverse charge the battery.

C: 2 3-phase AC motors of 150kW type.

D: Gearbox: Amplify the power of the rpm, the traction of the engine.

E: The charging system consists of 3 main levels:

• Level 1: Using 120V current: 1h can charge 3.2-8km.
• Level 2: Use 220V or 240V current: 1h can charge 16-40km.
• Level 3: Use a public fast charging station: 80% battery in 30 minutes.

Electric vehicles always have an inverter energy recovery system. Convert mechanical energy into electricity, charge the battery automatically when going downhill or winning again. Specifically, the inverter has the function of converting alternating current from the motor into direct current to recharge the battery.

Electric vehicle batteries are very large and heavy, so they are placed under the floor of the car so as not to take up vehicle space and help the car lower the center of gravity. Because it is under the ground, it is easy to collide, so it is reinforced with a lot of high-rigidity, sturdy aluminum frames to minimize battery damage, short circuit, fire and explosion when a collision occurs.

The 3-phase current will create a rotating magnetic field to make the rotor in rotation at a slower rate than the magnetic field speed. Through the gear system, the rotary transmission is amplified to increase the traction of the car.

Electric cars have a very simple structure, fewer components than gasoline cars. Because there is such a simple structure, there will be fewer failures. Maintenance, maintenance and repair costs are also greatly reduced compared to traditional gasoline and oil cars. Electric vehicle motors are very powerful and have little lag, so the acceleration speed is very high. For example, VinFast VF e34 and VinFast VF 9 accelerate from 0-100km/h takes 6.5 seconds, VinFast VF 8 takes 5.5-5.9 seconds.

Nhược điểm: Pin cần được thay thế khi đã hết chu kỳ sạc xả của nó. Tuy nhiên hiện tại các hãng sản xuất xe điện thường có chính sách cho thuê pin, và khi chu kỳ sạc của pin đã gần hết hoặc hết, người dùng có thể mang đổi pin thuê theo hợp đồng đã ký trước đó.

Xe điện không có ống pô nên sẽ không còn có thể độ pô tạo tiếng. Vì vậy đây cũng vừa là nhược điểm, vừa là ưu điểm của xe điện đối với mỗi người dùng.
