With the continuous popularization of new energy, the market for pure electric vehicles is getting better and bigger. Before the rise of BYD, it can be said that Tesla has always dominated the market. The entire market, in the pure electric field, not only has its own strong intellectual property rights, but also possesses certain technologies. It can be said that there are basically no opponents.
With BYD’s continuous efforts, it can finally compete with Tesla, but how big the gap between the two cars is, we have to analyze it from three aspects, that is There are three major components of fuel-powered vehicles. What is the difference between BYD and Tesla?
Speaking of the gap, BYD still has a bit of a gap, otherwise Tesla would not have been so popular in China. They occupy quite a lot of the market, although during this period there were Xpeng and Wei come, but in terms of market share, BYD and Tesla are relatively strong, so the comparison between the two is meaningful. Comparison one: motor
The most critical thing about pure electric vehicles is the motor. This is similar to the engine of a fuel vehicle. Whether a car is good or not depends on its engine. Otherwise, why are BMW, Mercedes-Benz, and Japanese cars so expensive? The key to why they all sell so well is that the engine is better. This is also recognized. So for electric vehicles, the first thing that needs to be compared is the motor.
Currently in the entire pure electric vehicle market, motors can be divided into two types, one is an asynchronous motor and the other is a permanent magnet motor. Tesla uses an asynchronous motor. This kind of motor has The advantages are: the structure is very simple, the price is relatively cheap, and the maintenance is relatively convenient.
The disadvantages are: relatively large size, poor speed regulation, and low light load power factor. BYD, on the other hand, uses its own self-developed permanent magnet motor. The advantages of this kind of motor are: relatively small size, small moment of inertia, and high power density. However, its disadvantage is that the price is relatively high and it is difficult to adjust.
The two can be said to be reversed. The advantages of asynchronous motors are the disadvantages of permanent magnet motors. Naturally, each car company determines based on its own choice. If you want to go long term, it must be independent. It's better to develop it because it won't be restricted.
The two have their own advantages in terms of speed. Taking Tesla as an example, under normal circumstances it takes about 5.6 seconds for Model 3 to accelerate from 100 kilometers to 100 kilometers, while BYD Han only takes about 3.9 seconds. , although there is a difference in price between the two, BYD's permanent magnet motor is still relatively good in terms of speed.
However, in terms of battery life, according to relevant data, with the same configuration and the same environment, BYD can drive 50 kilometers more than Tesla.
It can be seen from the motor aspect that BYD is obviously better than Tesla. Comparison 2: Battery
For pure electric vehicles, the battery is the second life span and the most critical factor. Whether the battery is good or not represents how far you can go. I believe this is also very important. Importantly, one of the biggest concerns of many people who buy electric cars is whether the battery is good and how far it can go. In this regard, I think BYD is better. Why do I say this? Let’s analyze and compare:
The batteries currently on the market can be roughly divided into two types, which are the two most common ones, namely ternary lithium batteries and lithium iron phosphate blade batteries. Lithium iron phosphate batteries are known as the safest vehicle battery technology, and this battery was independently developed by BYD. Tesla currently uses ternary lithium batteries, while BYD uses lithium iron phosphate blade batteries, which is something BYD has always been proud of.
Ternary lithium batteries can be said to have very high voltage, long cruising range, and relatively fast speeds. However, the disadvantage is that they have poor stability. If there is a short circuit in water or a collision, open flames can easily occur. , in severe cases, an explosion may occur. It can be said that the security is relatively poor.
The most critical point is that Tesla’s battery is purchased from outside and not independently developed. Our domestic listed company CATL is its supplier.
The advantage of lithium iron phosphate blade batteries is that the P-O bonds in the crystal are stable and safe. Even if some unexpected situations occur, the battery will not explode and it will last longer.
But there are also certain disadvantages, that is, the energy density is relatively low and the low-temperature performance is poor. There are no other big problems. The most critical point is that this battery is also developed by BYD itself. It can be said that the stability is definitely very high. So from this point of view, BYD is relatively good. Comparison 3: Electronic control
The electronic control of a pure electric vehicle is equivalent to the gearbox of a fuel vehicle. It is also very important because it is needed to control the stability of the entire vehicle. It is also what determines the stability of the pure electric vehicle. The stability of power output when the car is driving.
Among the three major items, the only thing Tesla can offer is this electronic control technology. This is independently developed by him, and it also has certain patented technologies, which can be said to be very good.
Similarly, BYD also has self-developed electronic control technology. Although it is not as good as Tesla's to a certain extent, this electronic control technology is still very advanced at least in China.
The most critical thing about pure electric vehicles is the motor and electronic control technology, because this is the biggest factor that determines their acceleration, high-speed running and climbing performance. From my personal experience, I think the two There is no big difference when climbing hills or at high speeds. Of course, it cannot be denied that Tesla’s electronic control technology is very good, otherwise it would not be possible for him to gain a foothold internationally. Comparison 4: Autonomous Driving
At present, Tesla’s autonomous driving can be said to be very good, at least at the same price point, it is still very leading. We still have to admit this. Because Tesla’s autonomous driving can be said to have been doing very well internationally. Autonomous driving seems to have appeared when Tesla was launched, but BYD currently has it, and only L2 assisted driving can be achieved.
But BYD boss Wang Chuanfu once said: " "Safety is the greatest luxury of electric vehicles." So whether autonomous driving is safe or not is also very critical.
So from the perspective of autonomous driving technology, BYD is still not as good as Tesla for the time being, but it is hard to say in the future whether it is possible to break through this situation, because Baidu has already launched autonomous driving. If If both parties can cooperate, this bottleneck should be broken. Comparison 5: Car-computer system
Tesla’s previous car-computer system can be said to not be very good, but with more and more subsequent accidents, people have also raised certain doubts, such as Crashes, jamming, slow response, and inability to recognize voices are still common occurrences, so Tesla is still relatively poor in terms of the car system.
On the other hand, BYD is still doing a good job, not only Han EV is doing a very good job, and even other models are also very good, so I personally think BYD is better at the vehicle system. Comparison 6: Appearance and Interior
When Tesla first entered the domestic market, it can be said that its appearance and interior were eye-catching, especially the scissor doors, which were a bit like a supercar. But with mass production and different needs, I feel that the current appearance is getting more and more ugly.
Anyway, BYD's appearance is becoming more and more refined, and it has also done very well in other aspects. The whole car looks very high-end and atmospheric, and it also integrates into our domestic history and culture. It can be said that it is still very good. The interior can be said to be finely crafted. From this point of view, BYD is still better.
So comparing these six aspects, although there is still a certain distance between BYD and Tesla, as time goes by and technology is updated, I believe that one day it will surpass Tesla. Become the first-class pure electric vehicle in the world.
Finally:
Why does BYD give people the feeling that there is some gap with Tesla? In fact, it is still a matter of brand influence, because BYD has always been a relatively low-end model in the minds of Chinese people. This is also The only way they could break into the market back then, but now it's still very difficult to establish a good brand.
Even though some of his models can now be the same as mid-to-high-end models, it is still difficult for people to accept the influence of his previous low-end brands. That’s why it gives everyone the illusion that there is still a big gap between BYD and Tesla.
