What is common sense when it comes to circuit boards?
The concept of Buffett stock refers to stocks that Buffett purchased based on his own calculations and speculations. Even if the benefits cannot be demonstrated in the short term, they can be effectivethese in the long term.
Buffett's investment in BYD appears to have violated his first commandment of investing: Never invest in a company whose business you don't understand. Even when the Internet stock bubble was at its peak between 1999 and 2000, Buffett did not buy stocks in the high-tech sector. BYD's battery, mobile phone and electric vehicle businesses can be considered complex and difficult to understand high-tech businesses. Buffett admitted that he didn't understand these three activities at all. Why would he continue to break the rules and invest?
Thanks to the recommendations of its two most reliable partners, Munger and Sokol, who knew these companies very well. Buffett thinks Munger is the smartest person in the world. Munger is very tough and never congratulates anyone easily. Munger declaredar that BYD CEO Wang Chuanfu is a combination of Edison and Welch. He is like Edison in solving technical problems, but like Welch in accomplishing the tasks at hand. So he asked Sokol, president of Sino-American Energy, to go to China to inspect BYD. After investigation, the three people were unanimously optimistic after research and decided to invest $230 million to buy 10% of BYD's shares. Although the investment is small, they consider it a big deal because they believe BYD is striving to become the world's largest automaker by making and selling electric vehicles.
In fact, Buffett did not break the rules when he invested in BYD. There was only one real reason for his investment: new energy. Buffett not only knows the energy sector very well, but he has also invested heavily in it.
Berkshire owns 84.7% of MidAmerican Energy. MidAmerican Energy owns several power companies with 18,000 megawatts of electricity generation capacity, serving 6.2 million electricity users in the United States and the United Kingdom.
In 2008, the total assets of Buffett's energy business were $41.6 billion, which accounted for almost one-sixth of the company's total sales profits. Nearly $3 billion. Buffett is very optimistic about energy-based utilities: "Charlie and I are very optimistic about our utility business. Last year's profit hit a record and the future outlook will be even brighter ."
And investing in BYD will enable us to extend Buffett's advantages in the upstream power generation sector to the downstream charging sector, making the future prospects of B's energy sectoruffett even more promising.
Just as fuel vehicle sales depend on the perfection of the gas station network, BYD dual-mode electric vehicle sales depend on the perfection of the charging station network in a region. Electric vehicles do not have the support of a large number of charging stations, just as current cars do not have the support of a large number of gas stations. It is impossible to promote them on a large scale. However, the construction of charging stations is not decided by companies. It involves many departments and interests, and the coordination time is also long.
Wang Chuanfu said that an important reason for choosing long-term cooperation with Sino-US Energy is that Sino-US Energy's extensive energy network and power transmission network across the United States can help BYD build a research stationmoney for electric vehicles. facilities in the United States in the future. : “BYD itself is also very interested in finding a long-term strategic partner, especially in the United States. Commercializing electric vehicles has always been our dream. In North America, relying on the reputation of Buffett and his company, as well as the help of Sino-American Energy, BYD can realize this dream more quickly. »
Buffett's approach is not to pan for gold, but to sell water to gold miners. The words of Sokol, president of Sino-American Energy, deserve more consideration: what interests us even more are BYD's fast charging technologies. These technologies can be applied not only to electric vehicles, but also to wind and solar energy. will have a lot of potential in the future field of environmental protection. BY's most profitable businessD in the future will not be the sale of cars, but the sale of fast-charging batteries. For Buffett, the most profitable thing is not the car or the battery, but the network of charging stations. BYD was the first to launch commercially available electric vehicles and build a network of charging stations across the United States. Oil companies that now own a network of gas stations across the United States enjoy a monopolistic network advantage. It's not just BYD's electric vehicles that will need charging in the future. In the economic recovery plan signed by the US president in March this year, electric vehicles were used as an asset to reduce dependence on foreign oil and save the automobile industry. Government funds used to develop, produce and encourage consumption of electric vehicle technologies amountent to $14.1 billion, which represents an unprecedented amount. How much money would Buffett make if a significant portion of his electric vehicles were charged at MidAmerican Energy charging stations? It's no wonder that Buffett said that buying BYD was a big deal at the moment, but was of great importance in the long term.
In fact, BYD is just a small pawn in Buffett's new energy setup. MidAmerican Energy is investing heavily to expand its wind power generation operations: “The ratio of MidAmerican Energy's wind power generation to total electricity generation has increased from zero to 20%. In 2008 alone, MidAmerican Energy invested US$1.8 billion in wind energy development. Today, it has become the largest wind energy company in the United States."
Buffett also purchased two shares ofenergy, CEG and NRG. Both companies have huge advantages in nuclear power and other related new energies. businesses.potential.
Buffett's stake in CEG has a market value of US$500 million. CEG is the largest electric company in the United States, with approximately 1.1 million electricity users and 570,000 natural gas users. It also successfully operates three nuclear power plants in the United States. In September 2008, Buffett announced that MidAmerican Energy Holdings had reached an agreement with CEG to invest US$1 billion in its acquisition at a price of US$26.5 per share. Later, in December, CEG agreed to acquire 50% of EDF's shares at a price of $45 per share. As a result, MidAmerican Energy received high compensation, investing $1 billion but getting back $2.1 billion.
Buffett's holdings in NRG havea market value of 168 million US dollars. NRG owns 44 power plants, mainly in the United States, with a generating capacity of 24,000 megawatts. It has gained great advantages in clean coal power plants. In 2007, she won the Platts Energy Award, the highest honor in the global energy industry. The company plans to spend $16 billion over the next ten years to build a number of “eco-friendly” clean coal power plants. Additionally, NRG will build the first nuclear superpower plant in the United States to be approved in 30 years, which will account for 44% of NRG's total electricity generation.
Different from those who only pursue concepts, Buffett's new energy investment method is to invest in energy companies that have a huge market share in new energy activities.s traditional energy activities while actively developing new energy activities. New energy businesses can be quickly sold in large quantities through the original channels, and old and new energy businesses can promote each other. Buffett can not only rely on traditional energy businesses for stable income, but also achieve huge future growth through it. a new energetic activity, both offensive and defensive. In fact, BYD's mobile phone batteries and traditional automobile business are quite remarkable. It was these traditional companies that gave the company the channels, funds and technical support to invest in electric vehicles, and also gave Buffett great investment confidence.
The Tesla Model Y is here, priced at €488,000, forrwhy don't you wait to see?
A little common sense about printed circuits:
1. PCB: A printed circuit board, also called a printed circuit board, is a basic component used to support and connect electronic components.
2. PCB level: The printed circuit board may be single or double panel, or it may be a multi-layer board.
3. PCB Materials: Common PCB materials include FR-4 fiberglass composite materials and aluminum-based materials.
4. PCB manufacturing process: PCB manufacturing process includes schematic design, layout design, PCB layout production, engraving, drilling, processing, surface treatment, assembly and welding, etc.
5. PCB Design Software: Common PCB Design Softwares include Altium Designer, Cadence Allegro, EAGLE, etc.
6. PCB Component Layout: In PCB design, the component layout should be reasonably arranged to meet requirements such as signal integrity, electrical connection, and thermal management.
7. PCB Testing and Debugging: During the production process, PCBs need to be functionally tested and debugged to ensure it is working properly. Common testing methods include electrical testing, visual inspection and functional verification.
8. IPC Standards: The IPC (Printed Circuit Institute) has developed a series of industry standards, such as IPC-A-600G (Circuit Board Acceptability Standard) and IPC-6012 (Performance of Rigid Circuit Boards). ) Specification), used to guide the design and manufacturing of printed circuit boards.
Tesla cuts leeks again! Not the ?S model, not the ?X model, not even the ?3 model.
On November 30, the Ministry of Industry and Information Technology released the “Catalogue of New Energy Vehicle Promotion Models” and the “Catalogue of New Energy Vehicles Exempt from the purchase tax”. Is Tesla Model Y listed? which means that the Model Y will be sold in the Chinese market.
In addition, judging from the declaration information, the Tesla Model? Y maintains the same appearance design as the foreign version, but the Chinese "Tesla" and model logo on the tail indicate that the car started localization at the Shanghai factory.
As early as August this year, Tesla China's official website opened the channel to accept the majority of consumers' (jiu) (cai) selection and reservation.
The new car will be launched in two models, a tralong-range all-wheel drive and a high-performance Performance version, with a pre-sale price of 488,000-535,000 yuan and is expected to be delivered in the first quarter of 2021.
What kind of car is the Model Y?
At first glance, this car looks like a stretched Model 3. I used to say that car models made their legs look longer and the cars next to them looked like SUVs. Well, Tesla made that statement come true. In the future, who will say that **sister P driving the Model 3 is too much, and just say, "I drive a Model Y."
Actually, Model? 3 and Model?Y are also preparing to be localized, and there is a strong possibility of price adjustments in the future.
In terms of battery performance, there is not a huge improvement over the Model 3. The long-range version of the Model Y has a cruising range of 594 km , less than the 668 km of the model3. Although it has an additional engine, the price will be more than 200,000 yuan?
Although my calculation is not accurate, after all, SUVs are incomparable with cars, but from the side it can be seen that this price is not profitable.
The market share of SUVs is close to that of cars, and there is a tendency to exceed it. This is very important for the market potential of Model Y.
In addition, in 2020, Tesla's market value suddenly exceeded that of Toyota, which had long occupied the first place , and is more than 8 times higher than that of General Motors.
Such success doubled Musk's confidence, and he publicly declared that the Model Y would become Tesla's best-selling model and that its sales would account for the combined sales of all others Tesla models.
So is it crazy to say that you're even going to drive your own Model 3?
Why is it called “And” ?
Let's see how Model?3 does it.
The first time the 2018 imported Model 3 met mainland Chinese consumers was at the Beijing Auto Show in April 2018. There was only two all-wheel drive models, and in November. announced at the Guangzhou Auto Show are 588,000 yuan and 698,000 yuan.
After launching in the Chinese market in early 2019, new models will be added, including the long-range rear-wheel drive version and the imported version of Model 3. There are already three models. on sale, priced at 433,000, 499,000 and 560,000.
In April, Tesla expanded the Model 3 lineup on sale to 4 models and added an upgraded lifespan version of the standard battery, priced at 377,000 yuan. After new models were added, the prices of the other three models were increased from RMB 5,000 to RMB 7,000.
In May, the first improved version of Tesla's standard Model 3 rangedomestically produced was launched, priced at 328,000 yuan, but it did not come standard with the AutoPilot automatic assisted driving function.
At the beginning of this year, the price of the domestically produced Model 3 was officially reduced by 32,000 yuan, bringing it into the 300,000 yuan range. And just in October, the price of the domestic Model 3 was reduced. The upgraded version of the standard battery life was priced at 249,900 yuan after subsidies.
In one year, the price of the imported standard battery life version of Model 3 was reduced from 377,000 to that of the domestic standard battery life version at 250,000.
In fact, it is not just Model 3. According to incomplete statistics, since Tesla entered the Chinese market in December 2013, until now, Model S, Model , Model 3 and Model Y. The official price ranges for all four models have been adjustedplayed a total of about 59 times.
At first glance, I think Tesla is just pricing, and A shares aren't as volatile as you are. In fact, this is not the case. Reducing the selling price is nothing more than a change in cost.
The reason for such a drastic reduction in Model 3 is due to several factors: first, it builds a factory in China, without paying customs duties, and its production capacity is significantly increased; localized, and Ningde is used instead. Era's lithium iron phosphate batteries are much more cost-effective than LG's ternary lithium batteries in terms of purchasing and transportation costs.
The most unfortunate thing is the car owner who bought a car at the end of September. He lost more than 20,000 yuan after just a few days of driving.
Are you buying the dip? Doesn't exist
According to the plant's manufacturing directorShanghai Tesla, the current localization rate of Model 3 parts made in China is about 30%. By the end of this year, all domestically produced Tesla Model 3 parts will be localized. In other words, the cost may go down and down, but what about the selling price...
Musc once believed that if there was enough technology to reduce the cost, there would be no price. We must use it wholeheartedly and will not consider the problems caused by price reduction.
This angers owners of old cars who bought early and profited early. Doesn’t that treat us like leeks? Future car owners who are holding the money and waiting to see it are happy to hear it. If it drops to 200,000, I will buy it!
However, the discontent of old car owners does not affect the Model 3 which is expected to sell more than 100,000units in 2020. Musk dances happily.
How can retail investors outperform bankers?
Facing challenges
Facing Tesla's momentum, Li Bin believes that it "does not pose a threat if it competes with Model Y, Weilai products will be better.” Have a competitive advantage.” When it comes to autonomous driving, Musk took the lead and scorned Xiaopeng for plagiarizing his code; He Xiaopeng also fired back, bluntly saying that Tesla would not find anything.
The more fun you all have, the more discounts we will get, and we will also be able to watch movies, which is very exciting.
When it built its factory in Shanghai, Tesla had a gambling deal with the Shanghai municipal government: it would acquire land at a very low price, but the Shanghai Gigafactory would have to pay taxes. every year from the end of 2023. 2.23 billion yuan. If this conditioncannot be fulfilled, the corresponding land must be returned.
Tesla is therefore not willing to become a price butcher. Musk also said he was willing to sacrifice profits and sell cheaper models in exchange for additional sales.
Therefore, if you want to make Model Y Tesla's best-selling model, and the sales volume will be the sum of the sales of all other Tesla models, if the price Current sales is not an easy thing.
After all, it has many competitors interested in it, and its own Model 3 models are taking market share, so lowering prices would be a better solution.
So what type of leeks will the current Model Y cut?
