China's new energy vehicle market is getting bigger and bigger, more and more prosperous, and has gradually become the world's first.
However, the "tires" of new energy vehicles can also become a separate market, have you heard of it?
These tires are engraved with the letters "EV", which represent the exclusive use, but ordinary fuel vehicle tires are engraved with the common tire model number. MoreoverThe EV** is significantly more expensive than regular tires.
In terms of speed, the gap between electric vehicles and ordinary fuel vehicles is not large, why are there special tires?Is this an IQ tax?
The reason why electric vehicles will make special tires is because they are fundamentally different from traditional fuel vehicles in terms of power release.
One of the reasons why electric vehicles are popular is because of itThe start-up is very fastAs long as the electric door is pressed, the motor in the electric car can react quickly within a few milliseconds, and it can also directly burst out of full power when it is stationary.
However, the power release of fuel vehicles is relatively slow, and it needs a gradual process. Fuel vehicles need to increase the ** and engine speed, and then transmit power to the gearbox, this process requires 0About 5 seconds.
The comparison can be seen that the electric car starts quickly, justAlthough electric vehicles started quickly, they are very lethal to tires。In millisecond reaction times, tires are subjected to tremendous stress. For electric vehicles to withstand this fast and efficient power release, they must use more powerful and durable tires.
In addition, although electric vehicles look different from the outside, the weight of electric vehicles is still very heavy. Traditional fuel vehicles only need fuel cylinders and refueling equipment, but electric vehicles also need to be equipped with batteries and motorsThe weight of an electric vehicle is 1 percent heavier than a traditional fuel vehicle of the same size5 to 2 times
The increase in vehicle weight places higher demands on the load-bearing capacity of tires. Electric vehicle tires need to be modified to take into account different situations, and the internal structural layer of electric vehicle tires with the "EV" logo will be specially strengthened, and more steel wires will be used to cope with higher load-bearing requirements.
So what is the difference between electric vehicle tires and ordinary fuel vehicle tires?
First of all, the tires of electric vehicles are different from those of traditional fuel vehicles in terms of material. Because electric vehicles have power batteries up to hundreds of kilograms of assembly, which need to bear heavier weight, car tires must also use more durable materials to improve the friction of tires and enhance the braking force of tires.
However, contrary to electric vehicles, fuel vehicles do not need to bear such heavy batteries, and even light tires can fully meet the requirements of use.
Secondly, because electric vehicles are clean energy, they only rely on electricity as power, so electric vehicles will not emit the noise generated by "burning oil" when the engine is started like traditional fuel vehicles. However, when an electric vehicle is driving on the road, the noise of the tires pressing on the road and the sound of the wind can become a major source of noise because the torque is transmitted to the road.
SoElectric vehicles require higher levels of quietness in their tires。Therefore, the difference between electric vehicles and fuel vehicles is that in order to improve the noise resistance of electric vehicles, the tire tread of electric vehicles will be specially designed with a pattern or increase sound-absorbing cotton to reduce road noise, but ordinary fuel vehicles do not need to do this.
Electric vehicles rely on power batteries to provide them with electricity, and in order to maximize the power efficiency and range of electric vehicles, it is very important to reduce rolling resistance. Manufacturers of electric vehicle tires often use low-drag materials to meet the requirements of electric vehicle tires with lower rolling resistance.
In order to reduce air resistance on tires and achieve these energy efficiency goals, electric vehicles use a relatively narrow ratio of tires to gasoline vehicles. Because the fuel vehicle uses the engine as the power source, it does not mainly consider the element of rolling resistance.
Finally, the tires of the electric car must be availableStrong grip。You must know that even pure electric vehicles weighing more than two tons can directly accelerate from zero speed to 100 speed in a few seconds. Such speeds require higher grip from EV tires to cope with the EV's enormous torque and ultra-fast acceleration.
Because electric vehicles themselves use clean energy, the material requirements for electric vehicle tires will also be pursuedRecyclableto achieve green development and recyclability of tires.
Compared with traditional fuel vehicles, electric vehicle tires are more in line with the needs of electric vehicles, so although they are all car tires, tires with the "EV" logo are still more expensive than ordinary tires without the "EV" logoSome can even differ by more than a third.
* The reason is that most trams on the market are still equipped with tires that traditional fuel vehicles are Xi used to, so can the tires of electric vehicles and fuel vehicles be mixed?
Although most electric vehicles on the market are equipped with traditional fuel vehicle tires, this does not mean that they can be mixed. First of all, electric vehicles and fuel vehicles also have great differences in tire design and performance due to their different needs.
Tires for electric vehicles and gasoline vehicles are very different in terms of the materials they need, the need for quietness, and the grip. If you mix the two types of tires, it is likely to affect the safety of the vehicle and the driving performance of the owner.
Therefore, we say that the special tires for electric vehicles are not suitable for fuel vehicles, and similarly, the tires of fuel vehicles are not suitable for electric vehicles. In order to ensure the safety and performance of the owner's driving, it is best to choose special tires suitable for electric vehicles, and adjust the tire pressure of your car according to the actual situation. To improve the electrical efficiency of the vehicle and extend the life of the tires.
Although electric car tires are more expensive, they have great advantages.
With the increasing number of electric vehicles, the rapid growth of electric vehicles has increased the demand for charging piles. For electric vehicles with electric drives, there is no electricity, that is, there is no advantage of affordable electric vehicles, but the reality is that the number of charging piles is very tight.
Although many people like electric vehicles, the reason why they are reluctant to buy electric vehicles is the trouble of charging electric vehicles, especially when driving electric vehicles far away, they often have to grab charging piles with others at rest stops.
If the electric vehicle is replaced with special tires and chooses tires with lower rolling resistance, it can save the power of the electric vehicle, reduce energy loss, and can well alleviate the range anxiety of car owners. There are many types of new wheels for electric vehicles that have shown excellent power-saving capabilities. For those electric car owners who have range anxiety, tires must be a reassuring pill.
For car owners who hate sharp car noise, although the electric car does not have engine noise, the speed of the electric car is too fast, resulting in its noise frequency is very high.
When the electric vehicle is driving at high speed, the noise of the motor is particularly obvious, which will cause great interference to the owner. Therefore, silent cotton and other silent devices will be specially set up in the special tires of electric vehicles, and the special tires for electric vehicles are better in terms of silence.
In solving the problem of grip of electric vehicles, the merchants of "EV" tires can be said to have made great efforts, and they have specially designed tires tailored for electric vehicles, so that tires, the only car parts in contact with the ground, can have better grip.
In general, the tires of electric vehicles can now have higher carrying capacity, more silent and comfortable, better speed grip, lower rolling resistance, etc., and can also use a variety of environmentally friendly new materials, "EV" tires can be said to better meet the needs of new energy vehicle owners, so electric vehicle tires are really not IQ taxes.
The ** of EV tires is relatively high, because this type of tire is designed to meet the unique needs of electric vehicles, and it is also a response to the performance needs, not a reflection of the IQ tax. Choosing "EV" tires ensures that electric vehicles can reach their full potential, providing a more efficient and safer driving experience.
More and more tire manufacturers are now launching products specifically designed for electric vehicles to meet the growing demand for electric vehicles.
So for electric car owners, electric vehicles put forward new requirements in many aspects, one of which is the choice of tires. When choosing tires, car owners need to learn how to choose tires.
The first is to pay attention to the wear resistance of "EV" tires, and car owners should choose tires with stronger wear resistance to avoid tire wear. The second is to pay attention to the grip of the tires. Electric vehicles should choose "EV" tires with stronger grip to avoid the problem of electric vehicle skidding.
Finally, electric vehicles should choose tires with lower rolling resistance, so as to avoid the owner often having to go to the charging pile to charge, so as to reduce the energy consumption of the vehicle and avoid mileage anxiety of the owner. Of course, these are the performance of "EV" tires, and ultimately it depends on the needs of car owners, and there are now various types of "EV" tires, which can meet different needs.
In short, although the special tires for new energy vehicles are a bit expensive, it is really not an IQ tax!Owners of electric vehicles, if they have comprehensive considerations and choices, can indeed choose tires for electric vehicles. What do you think are the advantages of new energy vehicle tires?
