In theory, if you want to increase the cruising range, you can directly increase the battery capacity. Mr. Wang Chuanfu once said that as long as BYD is willing, Tesla can be built in minutes.
However, there is still a gap between theory and practice. Although the cruising range cannot be used as a criterion to judge the quality of a car, with the same capacity battery, a longer cruising range and stronger power will undoubtedly occupy technical advantage. Below we use BYD EV450 and Tesla Model 3 to make a simple comparison:
Ministry of Industry and Information Technology pure electric range: Qin EV is
400 kilometers, Tesla Model 3 is 460 kilometers, the fast charging time is 1.5 hours for Qin and 1 hour for Model 3. The maximum power of Qin Motor is 160kw and Model 3 is 175kw. The maximum torque of Qin Motor is 310Nm and the maximum torque of Model 3 is 375Nm. Acceleration time to 100 kilometers: 7.9s for Qin EV450 and 5.6s for Model 3. From the above parameters, we can see that Tesla’s charging time is short, and its fast charging time is 1/3 faster than Qin’s. The power of Tesla's induction motor is about 1/10 higher than that of Qin's permanent magnet motor, and the torque is about 20% higher. Some people may say that Tesla’s higher mileage is due to its larger battery capacity. Let’s take a look at the battery capacities of the two:
It can be seen that the battery capacity of Qin EV450 is slightly higher than that of Tesla. However, various indicators and parameters are lower than Tesla. Here you can see the gap between BYD and Tesla. For batteries of the same capacity, the efficiency of the induction motor used by Tesla cannot be compared to BYD's permanent magnet motor, but in the end, whether it is power consumption, power cruising range, etc. Tesla has the advantage. So BYD electric cars don’t have cars with longer range? some!
Qin Pro
A super-powerful, high-power, high-endurance intelligent leading model with a cruising range exceeding Model 3. The Ministry of Industry and Information Technology has a cruising range of 520km, and the Tesla Model 3 has a cruising range of 460km. This cruising range is achieved by increasing the battery capacity. The Qin Pro battery capacity is 69.5kwh, which is 9.5kwh higher than Tesla. Here you can simply calculate the power consumption per kilometer of electric vehicles based on battery capacity and cruising range. BYD: 69.5/520=0.1336. The power consumption per 100 kilometers is 13.36kwh. Tesla Model 3:90/460=0.1304, power consumption per 100 kilometers is 13.04kwh. Although induction motors are not as efficient as permanent magnet motors, their final power consumption is not higher than that of permanent magnet motors. And the power/power is much stronger. Of course, there is a big price difference between the two cars, and BYD's price is lower.
Tesla seems to have nothing to offer except BMS (battery management technology). But Tesla has an advantage that no one else can match, and it can fully utilize the various technical advantages applied to the car. The power of integration is stronger, especially the battery management technology, and the fast overcharging speed is an obvious advantage. Although BYD can produce its own products and master core technologies, it does not mean that it can build Tesla. There is no need to build Tesla, as the development paths of the two are different.
This is just like domestic car manufacturers can build engines/gearboxes/chassis, but why is the fuel consumption higher than that of joint venture cars? Why do the same Aisin gearboxes get more complaints when they are used in Volkswagen cars? Although BYD can't build a Tesla right now, after mastering the three-electric technology, the road ahead will be much wider than Tesla's!
A bunch of nonsense answers, I will give you the correct answer. BYD's battery has a battery life that is 10% to 20% higher than Tesla's at the same volume and weight, which is often referred to as energy density. The reason why Tesla has a longer range than BYD is that it uses a method of stacking batteries. A car is stacked from beginning to end. The battery volume and weight far exceed that of BYD. However, the actual range is only 100 kilometers longer than BYD, so there is no need to kneel down and lick it. Tesla. Now BYD's 100,000 yuan class has a battery life of 405 kilometers. What about model 3? Let me ask you who is the best, everyone has a strong point in their mind.
Do you still remember the incident not long ago when a Volkswagen SUV copied the taillight design of BYD’s new generation Tang & Song Pro? It is clear that the plagiarist is the public, and it is clear that BYD is the one who is plagiarized, but it is still "beaten" by the trolls, even if this is a fact that the trolls cannot beat. It's really ridiculous, right?
Therefore, no matter how powerful BYD’s technological strength is, some trolls will never face up to the advantages of BYD, which is a self-owned brand!
Who is to blame? No one is to blame. If we are to blame, we can only blame BYD for having a bad background. He was born in China and deserves to be criticized!
Trolls have repeatedly mentioned that the BYD F3 copied the design of the Toyota Corolla. Yes, this is a fact, and BYD did not deny it, using a very humble way. The attitude is to grow by standing on the shoulders of giants. Trolls ignore that at the beginning of the development of the automobile industry, many brands started by imitating... Even though BYD has become very powerful, after years of hard work, it finally has its own decent product design, it is still tight. I grabbed it and didn't want to turn the page. What is the relationship between Volkswagen's imitation of BYD's design and BYD's previous history? How ridiculous! Why can’t Chinese people view independent brands with an objective attitude? To affirm the growth of this brand?
Also, could you please add prerequisites when comparing? Can it not be so unfair?
The prerequisites of the same price, same level, and same volume cannot be ignored, friends!
If you compare a car worth less than 300,000 yuan with a car worth more than 600,000 yuan, you are really good at it!
Also, Tesla’s reported battery life is actually what it is. Read more news and more real feedback from Tesla. Decay is a common problem for all batteries. , unless Tesla is not using batteries.
BYD car owners tell you that the Qin 70 has been driven for almost 2 years and now has a full battery life of 6. As a giant in the battery industry, the battery technology level is really not Damn, it’s really good to have such battery life.
Dear trolls, be merciful and be kind. Only if domestic products are good, the country will be better, and we will be better.
Let’s compare Tang EV and Maodou X at the same level.
Tang EV’s power consumption per 100 kilometers is 16.56, and Maodou X’s long-range version is 17.3.
Why is BYD inferior to Tesla?
However, in terms of battery life in actual tests, Maodou
It can be seen that Tesla’s battery life not only depends on stacking batteries, but also is a serious false standard.
When it comes to marketing and brand value, BYD is no match for Tesla. When it comes to technology, BYD crushes Tesla.
Apart from anything else, it is well known that BYD’s batteries are so safe that they are used in national defense. From the first F3DM to the current fourth-generation DM technology, there has not been a single battery fire incident. Since it is an electric vehicle or a battery vehicle, of course the safety of the battery is the most important thing. Looking back at Tesla, there have been more than a dozen cases of death due to battery fires reported in the news at home and abroad since its launch. There is no guarantee of safety. This is in line with the topic of your question. Currently, BYD's battery density and safety are among the leaders in the industry. It cannot be said that Tesla has not surpassed BYD in a single model, but the safety gap between the two sides is huge.
BYD’s mastery does not mean it is excellent, and Tesla’s use of supplier’s technology does not mean it is a bad guy.
First, let’s talk about BMS. The battery management system BMS is the industry leader. No one dares to say it is number one. This is the technology that Tesla can bring to the table.
Secondly, let’s talk about battery technology. The Panasonic 21700 used by Tesla has an energy density of 300wh/kg, which is world-famous. The most powerful ternary lithium battery in China is currently produced by CATL, which is expected to have stable mass production of 250wh/kg by 2025. BYD is at most similar to this level. Therefore, BYD's battery of the same weight will definitely not be able to outperform Tesla.
Let me add here, why do domestic car companies not buy Panasonic's 21700 or LG's soft-pack lithium batteries when first-class battery suppliers have such excellent technology? That's because these batteries are not made in China and cannot enjoy policy subsidies. Therefore, orders from CATL and BYD have been soft. With the opening of the white list in China, Panasonic, LG Chem, and Samsung SDI have all jointly built factories in China. The three major domestic Suppliers CATL, BYD, and Guoxuan are bound to be impacted. The domestic model 3 newly released in the past two days uses subsidized LG Chem batteries. Although the mileage is reduced compared to Panasonic batteries, it is still very competitive.
Finally, let’s talk about the motor. The motor used by Tesla is an asynchronous motor, which is also supplier technology. This technology is two different approaches from BYD’s permanent magnet motor. Asynchronous motors have complex structures and high costs, but they have good high-speed performance and long endurance. Permanent magnet motor has simple structure, good reliability and low cost. So to sum up, even if BYD maintains its own core technology, it is not the most cutting-edge technology. Self-research ≠ leading. So the battery life is definitely not as good as Tesla.
Nothing is absolute.
Why can Japan, Germany, and the United States build beautiful cars? Because they have a strong industrial base. Now our country also has an industrial base that is comparable to other powerful countries. It also has the world's leading battery technology, Mercedes-Benz and Toyota. Being able to put down one's posture and cooperate with BYD shows that BYD has extraordinary abilities.
If the Chinese themselves look down upon themselves, don’t expect those barbarians and Japanese dogs to look down upon you! Chinese people and products should be confident, self-reliant and self-reliant!
If BYD’s 100,000 yuan car has a range of 400 kilometers, Tesla’s 300,000 yuan car should have a range of 1,200 kilometers.
There are BYD cars all over the street, and they say Tesla is good, maybe they have ulterior motives! Why didn’t you see how many Teslas were driving on the street? It shows that it is not popular among users! So don’t push anyone to be better than others all day long! If there are not many users, it means the product itself is not good! The only way to do this is if someone buys it!
I believe in BYD. First of all, I believe in Wang Chuanfu, because Wang Chuanfu is a great entrepreneur and technical expert in China, and because he is Chinese. If the Chinese themselves do not support BYD, how can they expect it to compete with the United States? People compete? Besides, BYD is the well-deserved leader in the field of electric vehicles in China. The E5, Qin, Tang, Song, Yuan and the soon-to-be-launched Han, with prices ranging from 100,000 to 300,000, basically meet the needs of the Chinese people in the era of electric vehicles. While technology is improving, Car styling is also gradually adapting to new trends. Just after Tesla achieved localization, there was a scandal over distribution reduction, and it also responded domineeringly to Chinese people’s doubts on Twitter.
Even though I speak softly, even though I am born with a complex of national independent brands, I still call on the Chinese people to support BYD, just like the Koreans support Hyundai and the Japanese support Toyota and Honda, so that Chinese independent brands can be the first to China has taken deep roots!
