Many people have this question: Some electric cars look similar. Why are brand electric cars so much more expensive than brand electric cars? For this question, many people may say that brand electric vehicles are well advertised. In fact, there is a great difference in quality between brand electric vehicles and brand electric vehicles. So, what is the difference between a brand-name electric car and a brand-name electric car? Today I will give you an analysis from 1 aspects!

first, analysis from the external plastic shell

The plastic shell of brand electric vehicles is generally made of ABS material, which has higher hardness, more collision resistance and is not easy to break. However, the inferior propylene material is usually used in brand-name electric vehicles, and the price of this material is generally only half of that of ABS material, and it is easier to crack and less sturdy when it is hit.

second, from the analysis of the frame, the frame of

brand electric vehicles is made of steel that meets the national standard, and its strength is greater, and it is not easy to rust and will not break. The electric vehicles with miscellaneous brands are usually steel products that do not meet the national standard, which are not only easy to rust, but also easy to break. < P > Third, from the motor analysis, the motor selection of < P > brand electric vehicles is basically the first-line motor brand, which has lower power consumption and longer service life. But the inferior brand electric vehicles often use some low-priced motors or even refurbished motors, which have serious demagnetization, higher power consumption, short service life and lower endurance.

fourth, from the controller analysis

the controller selection of brand electric vehicles is generally brand controllers, which are relatively stable, with good sealing performance and low probability of getting wet. However, the inferior controller is generally chosen as the controller of the miscellaneous brand electric vehicle, which is unstable, has worse voltage limiting ability and is easy to be damaged.

V. Analysis of batteries

Most of the batteries of brand electric vehicles use first-line brands such as Tianneng, Chaowei and Xupai, and their endurance and life span are longer. The batteries of electric vehicles with miscellaneous brands generally choose refurbished batteries or counterfeit brand batteries, which not only have short battery life, but also are more prone to problems.

VI. Analysis from chargers

The chargers of brand electric vehicles are all made by themselves or selected from well-known chargers in the industry, which are relatively stable and have charging protection, so that the batteries will not be damaged. In order to make a profit, the brand-name electric vehicles are more low-cost chargers, which have worse stability and are more likely to charge batteries.

VII. Analysis of welding process

Brand electric vehicles use robot welding, which has stronger stability, while brand electric vehicles are often manually welded, which not only leads to uneven welding joints, but also has worse stability.

VIII. Analysis from painting

Brand electric vehicles use high-end painting technology, which is not easy to fall off. But the brand-name electric vehicles use ordinary ready mixed paint, which is influenced by the external environment, so it is easy to fade.

IX. Analysis from Wheel Hub

Brand electric vehicles use wheels with better quality and greater strength, while brand electric vehicles use wheels with lower strength.

X. Analysis from handbrake

Brand electric vehicles are all brand handbrakes with relatively good quality, and the braking effect is better, while brand electric vehicles are often handbrakes with poor quality.

in fact, although brand electric vehicles and brand-name electric vehicles look similar in appearance, their quality is quite different. Therefore, users are advised to choose brand electric vehicles with better quality when choosing electric vehicles. Finally, one thing reminds users that small-brand electric vehicles are not miscellaneous cars, so don't confuse them.

electric vehicles, that is, electric drive vehicles, also known as electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, the electric vehicle is a vehicle that uses the battery as the energy source, and converts the electric energy into mechanical energy through the controller, motor and other components to control the current and change the speed.

the first electric car was made in 1881 by the French engineer Gustave Trouvé Gustave Trouve (also known as Gustave Truff). It is a tricycle powered by a lead-acid battery and driven by a DC motor. Today, electric cars have undergone great changes and various types.
