[Aika Car Car Culture Original]
Looking down from the sky above Shanghai's Lingang New Area, a white factory shaped like a battleship has become a hot topic in the automotive circle in the past two years, with an area of 860,000 square meters, not even half of other traditional car factories, but every 38 seconds can let a Tesla drive out of the production line, this annual production capacity of more than one million super factory, from design and construction to operation management, seems to be everywhere to interpret elon Musk's "first principle".
On March 3, tesla GIGA museum parachuted into the Tesla center of Beijing Crab Island, equivalent to the reproduction of the Shanghai super factory workshop, scenario-based to the public to show the Tesla vehicle manufacturing links, and invited the first batch of users to visit. Visitors learned about the birth of Tesla vehicles at zero distance at the GIGA Museum, and deeply felt the charm of Tesla's intelligent and environmentally friendly manufacturing concept and Chinese manufacturing concept in graphics, videos and interesting interactive gameplay.
Tesla "star factory" to Beijing, GIGA Museum and other than the presentation of cutting-edge technology
In the GIGA Museum, Tesla innovatively "moved" the highly acclaimed and concerned Shanghai Gigafactory progress hall, from the die-casting workshop, stamping workshop, to the welding workshop, the painting workshop, and then to the battery/motor workshop, the assembly workshop, the audience walked through the entire exhibition hall, just like the whole visit to the Tesla Shanghai Gigafactory, to understand the complete process of the birth of a Tesla vehicle.
The "Die Casting Workshop" and the like scaled down the iconic Tesla Red and White Die Casting Machine, showing the die-casting process of the Model Y rear plate. Tesla die casting workshop is equipped with the world's rare 6000 tons of pressure casting machine, using integrated die casting technology, can achieve Model Y rear plate integration structure 180 seconds rapid die casting molding, reducing more than 70 parts to 1 part. This not only reduces the weight of parts by 13%, improves Model Y performance and endurance, but also reduces the man-hours and costs of more than 1,000 welding processes in the rear bottom plate welding line, saves manufacturing costs by 20%, and saves 30% of factory land area.
In the "welding workshop", Tesla directly moved the steel and aluminum hybrid body-in-white to visually show the welding process. Tesla GIGA welding workshop adopts online measurement, automatic assembly system, virtual debugging and other technologies to optimize manufacturing efficiency and improve body dimensional stability. With the blessing of intelligent production, Tesla vehicle body can withstand more than 90,000 Newtons of roof pressure, nearly 6 times the weight of the body, equivalent to 2 African elephants, and the strong pressure resistance protects the owner's travel safety.
In the "battery/motor workshop", Tesla demonstrated its original design and production of motors, with the significant advantages of high integration, higher voltage, higher speed, can achieve 80%-95% of the work efficiency, much higher than the internal combustion engine 38%, both "high performance" and "high efficiency".
The last stop, "Assembly Workshop", let the audience understand that the tightening electronic wrench with the bolt of wireless transmission can upload all the data to the database, realize the real-time monitoring of the whole process of manufacturing parameters, automatically upload the background database and can be traced for a long time, and maintain real-time information exchange between the factory network and the vehicle driving computer, so that the vehicle can automatically complete self-testing and learning calibration work during the manufacturing process. The final assembly workshop of Shanghai Gigafactory is currently the world's leading digital assembly workshop.
At the same time, in each simulation workshop, Tesla also prepared interesting interactive sessions for visitors, such as the T Logo custom fire paint stamp in the die-casting workshop, the nail-type press-type reproduction board in the stamping workshop, the building block car splicing in the welding workshop, the coloring DIY in the painting workshop, etc., so as to let the audience experience the birth process of a car.
Intelligent manufacturing sets an industry model, energy saving and carbon reduction pass on the concept of environmental protection
The GIGA Museum allows the audience to visit Tesla Shanghai Gigafactory, showing the scientific and technological heritage and environmental protection concept of this digital and intelligent green gigafactory. It has a world-class data center, in the raw material transportation, parts production, testing and other processes have been automated, information; full implementation from the supplier side, to the parts inspection, to the manufacturing process, and then to the customer use of the whole life cycle of quality control with a full life cycle product quality management system, to ensure the quality of the vehicle and parts.
In the Tesla Super Factory, the leading assembly line is Tesla's independent research and development of the production and manufacturing control system (MOS), which has human-computer interaction, intelligent identification and traceability functions, which can be deeply applied to vehicle manufacturing, battery workshop, motor workshop, etc., and is a digital model in improving the process, engineering design, quality control and other aspects. In addition, each process covers a highly reliable industrial network, providing perfect network services for equipment automation, wireless connection of production equipment, production information data collection, human-computer interaction, and intelligent decision-making.
While meeting the annual production capacity target of more than 450,000 vehicles, the localization parts rate of the Shanghai Gigafactory has also reached 90%, and Tesla's "sustainable" environmental protection concept has been deeply practiced. At the beginning of the design, the Shanghai Super Factory formulated the optimal factory process control, so that the truck carrying the production materials was unloaded directly at the intersection of the required parts of the production line to reduce the emissions generated by transportation; it also improved the reuse rate of industrial solid waste resources to more than 94% with science and technology, and handed over all the scrap batteries to the battery recycling whitelist enterprises for recycling, reusing more than 150,000 tons of reclaimed water every year, processing the organic waste of the painting and battery workshops, and using lithium batteries for forklifts and employee shuttles. Eventually, it will become a model of "environmental protection factory" in the world, realizing the reuse of 92% of the battery raw material metal, 96% of the waste recycling, and 100% harmless treatment.
Tesla's "star factory" not only achieved production capacity records and a number of environmental milestones, but also demonstrated efficiency as the best interpretation of "Shanghai speed". Covering an area of more than 1,200 mu and more than 860,000 square meters, the Shanghai Gigafactory, an area of about 120 football fields, officially started construction on January 7, 2019, and it took only 10 months from foundation laying to production. In September 2021, Tesla landed in the Shanghai R&D Center with the same efficiency, which is Tesla's first overseas R&D center, and is carrying out diversified local development work around vehicle development, energy products, charging equipment, etc.
It is precisely because of Tesla's advanced manufacturing concept and strict quality control standards that Tesla vehicles made in China bring consumers the most sincere price and ultimate quality. Tesla Shanghai Gigafactory has also sent Chinese quality overseas, allowing more consumers around the world to enjoy the high quality and cost-effectiveness of Chinese manufacturing, which has won wide praise from overseas users.
The GIGA Museum erected "three walls" to encourage the public to pay attention to environmental protection
The GIGA Museum not only shows Tesla's achievements and enlightenment in manufacturing, but also sets up energy walls, environmental protection walls and patent walls to attract more people to pay attention to energy conservation and environmental protection and industry development issues.
In terms of charging network construction, Tesla has built and opened more than 1,100 superchargering stations and more than 8,400 superchargering piles in Chinese mainland, with more than 700 destination charging stations and more than 1,800 destination charging piles, covering more than 360 cities and regions. At the same time, more economical, efficient and intelligent third-generation home charging piles have also been rapidly promoted in China, allowing more car owners to enjoy a worry-free energy replenishment experience.
Thanks to clean production links, extensive charging network, and a large group of car owners, Tesla has achieved excellent results in energy conservation and carbon reduction. According to the "2020 Tesla Impact Report" data, the total emissions per mile of Tesla vehicles are much lower than that of fuel vehicles, and the Model 3, as the most energy-efficient model at present, consumes only one-tenth of the energy consumption of fuel vehicles. In 2020, Tesla's cars and solar panels around the world helped users save a total of 5 million tons of carbon dioxide equivalent.
In order to allow more partners to join the team of energy conservation and carbon reduction, since 2014, Tesla has opened more than 300 patents. The Dojo supercomputer released in 2021, Tesla also plans to open up to other companies for use, jointly promote the realization of driverless driving, so that Tesla's technology can benefit the whole society.
As the base point of Tesla's development in China, Shanghai Gigafactory is based on scientific and technological concepts and mature experience to create an advanced, green and sustainable factory model, with production capacity taking into account both the Chinese market and overseas exports, driving the coordinated development of the upstream and downstream of China's new energy vehicle industry chain. The opening of the GIGA Museum provides a window for the public to understand the world's cutting-edge smart factories, and has also become a popular punch card in Beijing, inspiring and attracting more people to join the team of "promoting the world's transition to sustainable energy".
