Many people have this question: Some electric vehicles look similar. Why are brand-name electric vehicles much more expensive than brand-name electric vehicles? Regarding this issue, many people may say that branded electric vehicles are good at advertising. In fact, this is not the case. There is also a big difference in quality between brand-name electric vehicles and non-brand-name electric vehicles. So, what is the difference between off-brand electric vehicles and brand-name electric vehicles? Today I will analyze it for you from 10 aspects!
1. Analysis from the outside of the plastic shell
The plastic shells of brand electric vehicles are generally made of ABS material, which has higher hardness, is more resistant to collision, and is not easy to break. Other brand-name electric vehicles usually use low-quality acrylic materials, which are generally only half the price of ABS materials. They are more likely to crack and have poorer sturdiness when subjected to collisions.
2. Analysis from the frame
The frames of brand electric vehicles are made of steel that meets national standards, and are stronger, less likely to rust, and less likely to break. And miscellaneous electric vehicles are usually made of steel that does not meet national standards, which is not only easy to rust, but also easier to break.
3. Analysis from the motor
The motor selection of brand electric vehicles is basically the same. It is a first-line motor brand with lower power loss and longer service life. No-name electric vehicles often use some low-priced motors or even refurbished motors. This kind of demagnetization is serious, the power loss is higher, not only the life is short, but the endurance is even lower.
4. Analysis from the controller
The controller selection for brand electric vehicles is generally a brand controller, which is relatively stable, has good sealing performance, and has a low chance of getting wet. As for the controllers of off-brand electric vehicles, they generally choose inferior controllers that are unstable, have worse voltage limiting capabilities, and are easily damaged.
5. Battery analysis
Most of the batteries of branded electric vehicles use first-tier brand batteries such as Tianneng, Chaowei, and Xupai, which have longer endurance and longer life. As for the batteries of off-brand electric vehicles, they generally choose refurbished batteries or counterfeit brand batteries, which not only have a short battery life, but are also more prone to problems.
6. Analysis from the charger
The chargers of brand electric vehicles are all manufactured by themselves or use well-known chargers in the industry. They are relatively stable and have charging protection, so there is no need to Will damage the battery. In order to make profits, unknown electric vehicles use low-priced chargers, which are less stable and more likely to damage the battery.
7. Analysis from the welding process
Branded electric vehicles use robot welding, which is more stable, while miscellaneous electric vehicles are often welded manually. Not only are the solder joints uneven, but also The stability is worse.
8. Analysis from the spray paint
Brand electric vehicles use high-end spray paint technology, which is not easy to fall off. However, other brand-name electric vehicles use ordinary mixed paint, which is more likely to fade due to the influence of the external environment.
9. Analysis from the wheel hub
Branded electric vehicles use wheel hubs with better quality and greater strength, while non-branded electric vehicles use wheel hubs with lower strength.
10. Handbrake analysis
Brand-brand electric vehicles all have relatively good-quality brand handbrakes with better braking effects, while miscellaneous brand-name electric vehicles often have poor-quality handbrakes. .
In fact, although branded electric vehicles and off-brand electric vehicles look similar in appearance, their quality is quite different. Therefore, it is recommended that users try to choose electric vehicles from brands with better quality when choosing electric vehicles. Finally, one thing to remind users is that small brand electric vehicles are not no-name vehicles, so don’t be confused.
Electric vehicles are electric vehicles, also known as electric vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles are vehicles that use batteries as their energy source and convert electrical energy into mechanical energy for movement through controllers, motors and other components to control the size of the current and change the speed.
The first electric car was manufactured in 1881. The inventor was the French engineer Gustave Trouvé (also known as: Gustave Trouvé). Tricycles powered by lead-acid batteries are driven by DC motors. Today, electric vehicles have undergone tremendous changes and come in many types.
