Tesla and BYD are completely different types of car companies. Tesla mainly relies on the integration of global supply chain, and both motors and batteries are purchased from suppliers. As long as it gets the software system, BYD is self-sufficient, and most of its components are produced independently, focusing on hardware. Therefore, the car-making ideas of the two are completely different. So BYD's advantage mainly lies in hardware, while Tesla's advantage mainly lies in software.
Advantages of BYD
1, more patents
According to the list of the top 20 enterprises of new energy vehicle patents, BYD ranked first with 9,426 patents, higher than the sum of the second and third patents. By the end of 20 18, 12 and 3 1, Tesla had 375 new energy vehicles worldwide. BYD holds a large number of patented hardware technologies, which Tesla can't catch up with, while Tesla's patents mainly focus on software such as electronic control, vehicle control, fast charging and automatic driving.
2. Self-sufficiency in hardware
BYD's motor, battery and electronic control system are all self-sufficient. In contrast, Tesla's batteries are purchased from Panasonic and Contemporary Ampere Technology Co., Ltd., and the motors are from Futian. Only control technologies such as BMS (Battery Management System) and motor control are independently developed by Tesla. The advantage of self-sufficiency in supply chain parts is that it can better verify the whole vehicle, ensure the consistency and stability of supply chain products, and better control the cost.
Tesla recently frequently suspected brake failure, which may be due to problems in product matching and integration.
3. The assembly process and quality are better.
After all, BYD is a traditional car manufacturer who has built cars for many years and has more experience in manufacturing. Except that BYD's steering wheel was a little crooked not long ago, there was basically no major assembly process problem. Tesla's skylight leaks and the seams are uneven, which leads to various minor problems in later use. BYD is undoubtedly more stable in quality.
4. The interior design and materials are more exquisite.
Tesla's interior has a sense of science and technology at best, but it's hard to say that there is no interior design, giving you a whole big screen, and the rest are all hard plastics and no instruments. Anyway, I don't quite understand that some people like Tesla's interior. BYD's interior is much more normal, and the interior materials should be more particular.
5. Better security
Tesla spontaneously ignited frequently. Some people say that BYD has never spontaneously ignited. In fact, BYD also spontaneously ignited. In 2020, there will be spontaneous combustion 13 vehicles, all of which are lithium batteries. BYD's blade batteries are safer. After BYD replaced the blade battery, we can think that BYD has a low risk of spontaneous combustion. In addition to spontaneous combustion, Tesla's suspected brake failure and automatic driving system bugs are all factors affecting safety.
Tesla's advantages
1, software-driven hardware
In the traditional automobile era, we often hear the saying that fuel vehicles are usually replaced once every three years and the models are changed once a year. However, in Tesla, there is no such thing as substitution, because Tesla is software-driven hardware. At first, the vehicle will be given a better hardware foundation, and then the vehicle system will be updated through OTA upgrade to enhance the experience and the ability to eat all the hardware. In this regard, BYD is more of a traditional car-making idea.
2. Automatic driving system
Although the so-called automatic driving system is not available in Tesla, Weilai or Tucki, and it only assists driving, in this respect, Tesla is obviously better than BYD. BYD's autopilot system, now using Bosch scheme, can't even do the most basic ACC adaptive cruise well.
3. Automotive system design
Tesla's model, among other things, the logic of the car-machine interaction system is clear, and the design of the car-machine system is also very scientific. Compared with BYD, the car-machine system is not scientific enough, not cool enough, and the interactive logic is chaotic. BYD hopes to do everything by itself, but there is still room for improvement in car-machine system and product design.
