In the early morning of September 23rd, Beijing time, Tesla Battery Day in 2020 was held in the California factory as scheduled. It is worth mentioning that due to the epidemic, all the participants were sitting in Tesla cars, only Musk shouted on the stage, and the participants were replaced by Tesla speakers.
So, what innovations did this high-profile conference bring? Let's watch together.
4680 electricity?
Will reduce the battery cost to the end.
On battery day, the most important innovation naturally comes from the battery itself, and the brand-new 4680 battery is undoubtedly the biggest concern in this field.
At present, Tesla has three battery sizes: from the original "1865"? (The first two digits are the diameter, and the last two digits are the length) increased to "2 170" of the previous generation, and now it will increase to "4680".
The brand-new 4680 battery is the practical application of Tesla's "electrodeless ear" battery patent disclosed in May this year. Its core design concept is that the positive and negative current collectors are directly connected with the cover plate/casing, which increases the current conduction area and shortens the current conduction distance by times, thus greatly reducing the internal resistance of the battery, reducing the calorific value, prolonging the battery life and improving the peak power of charge and discharge.
How to reduce the cost? It is the main driving force for Tesla to constantly change the size of the battery.
According to reports, the new battery will remove the battery ear through laser technology, which will increase the single energy by 5 times, the cruising range by 16%, the power by 6 times and the battery cost by 14%.
In addition, Tesla also optimized and expanded the industrial process of the battery production line, and adopted the dry electrode process, which can simplify the operation 10 times compared with the traditional scheme. The battery production line also adopts high-performance assembly line, hoping to realize continuous assembly and processing. In this way, on a production line, the battery output of 20GWh can be achieved, which is 7 times higher than the current production efficiency. In this way, the whole plant can reach TWh level production capacity, and the annual production capacity of 3TWh can be realized in the next 10 year.
On the whole, it is the core demand of Tesla's future battery planning to optimize the battery structure components, simplify the battery production process, improve the battery standardization capacity, and finally achieve the goal of reducing the battery cost.
Tesla also said that battery day will be a battle for the cost of electric vehicles.
This year's delivery has increased by 30%
The output of Shanghai factory is 6,543,800+0,000 vehicles.
Musk said at the event, "In 20 19, Tesla's delivery increased by 50%. In 2020, despite the epidemic, Tesla's delivery will increase by 30-40%. " Does this expectation mean that Tesla will deliver this year or will deliver it? 477750? Where to? 5 14500? A car is expected to complete Tesla this year? 50? /kloc-the delivery target of 0/0,000 vehicles.
At the Battery Day, Musk once again published a madman's quotation-the traditional fuel car company will no longer exist in the future, and conveniently planned its own electrification blueprint.
Musk said that Tesla is the only automobile company in China with 65,438+0,000% foreign investment. In the past year, Tesla set up a factory in Shanghai within 1.5 months. At present, the second phase expansion of the Shanghai plant is in progress, and it is estimated that the Shanghai plant will achieve the production target of 654.38+0000 vehicles annually in the future.
Recently, a number of foreign media reported that among the 908,965,438+0 electric vehicles delivered by Tesla in the second quarter of this year, the Shanghai Super Factory produced 29,684 vehicles, accounting for 32.6% of Tesla's delivery of electric vehicles this quarter, nearly one-third.
According to the quarterly output of 30,000 vehicles (output in the second quarter of this year), the current annual output of Tesla Shanghai Plant is about 6,543,800+2,000 vehicles. Achieving the annual output target of 6,543,800+million vehicles means that the output of the Shanghai factory will increase by 7 times.
In addition to the Shanghai factory, in terms of factory expansion plan, Musk said, "We hope to have Tesla factories on every continent, which can ensure the company's liquidity and delivery cycle; We currently have a factory in China, two factories in the United States and a factory in Europe. We hope to establish a factory in Australia in the future. "
Musk also said that he hopes to produce about 20 million cars every year, but it will take 65,438+0-3 years to achieve it.
What other information did Battery Day reveal?
On the battery side, there is new news. Musk announced that in energy-intensive vehicles, such as Cybertruck and Semi, Tesla will use 100% nickel to support the battery, the so-called "all-nickel battery". In order to meet the increasing demand for nickel metal and reduce the cost of nickel mining, Tesla even personally participated in the whole process of nickel mining as a miner.
Battery Day also brought the news of "Cheap Tesla". Musk said that after about three years, he is confident that he can create a very attractive fully automatic car with a price of 25,000 US dollars (about 1.7 million RMB). At present, Tesla's lowest-grade model? Model 3 starts at $37,990 in the United States. This means that in the next few years, the price of Tesla's cheapest model will drop by 34%.
Regarding the automatic driving software update, Musk said that Tesla will push the beta version of the fully automatic driving (FSD) function in about one month.
In addition, at the battery day event, Musk also showed off the new plaid? Models? S, according to the information of Tesla official website, the acceleration time of 0- 100km is less than 2 seconds, the top speed can reach 320km, and the cruising range can reach 832km. At present, this model has accepted the reservation, and the price is 139990 USD. It is expected to be delivered in the second half of 20021.
Regarding when these technologies will land, Musk said on social media that all products of "Battery Day" will be mass-produced before 2022.
Red dot observation
Heroes make the situation. What Tesla is most worth learning is its leading role in the industry. Just like Apple's mobile phone, it has irreplaceable absolute authority in the definition of many future technologies and the formulation of industry standards. What's more commendable is that Tesla's focus has always been on how to reduce product costs, which is the core to enhance the competitiveness of Tesla products. For us, the new forces that build cars, there is still a big gap in this respect.
