At present, with the aggravation of global warming, it has become the consensus of all countries in the world to accelerate the pace of realizing the “dual carbon” goal.Developed countries, such as Europe, America and Japan, have set the target of carbon neutrality at 2050 after reaching the carbon peak.As the world’s largest energy producer and consumer, China’s efforts to reduce carbon emissions have been closely watched.China has previously set a “dual carbon” strategy to peak carbon emissions by 2030 and become carbon neutral by 2060.Without peaking, China’s timetable is only about 10 years behind that of developed economies.In comparison, China’s dual carbon strategy can be said to be more urgent and heavy task.To implement the “dual carbon” strategy, the primary task is to save energy and reduce emissions.According to relevant data, electricity, transportation and construction (industry) account for 41%, 28% and 31% of carbon emissions respectively.New energy car belongs to the transportation sector, and its factory covers building, electric power, industry, is one of the few to cover more than a few in the field of industry, because car manufacturers to build factories, need to buy land from the government, then looking for design unit, construction unit construction, and finally, add water, the process is the same as the real estate development and construction industry;In the production process after the completion of plant construction, the factory needs to consume a lot of power resources for industrial production when producing cars. Last year, the industrial power rationing in some areas also reminds enterprises of the importance of energy conservation and emission reduction.Therefore, new energy enterprises in the “double carbon” strategy of the excellent case has a more exemplary role.In the case of new energy enterprises we study, there is a new force of car making performance eye-catching.Building cars new forces has just started in 2016, when the industry by foundry pattern is common approach, but less so for environmental control of the plant, and the new force is very enterprising, and spend heavily on self-built factory, is the first new force to build the factory car companies, carbon reduction in the road, in the factory have a starter experience, also has more research value.This enterprise is one of the head players of the new force of car making at present weima Automobile.Statistics show that Weima has delivered nearly 90,000 vehicles to consumers in more than 200 cities in China.The total mileage of users is about 2.4 billion kilometers;It helped reduce carbon dioxide emissions by about 640,000 tons, the equivalent of planting a forest of 60,000 hectares.To do a good job, he must sharpen his tools.Leading delivery comes from excellent product force, and excellent product force comes from advanced new energy manufacturing plant.Under the general premise of “double carbon” strategy, Weima factory can be said to be a typical model.In the era when most new forces blindly seek fast and adopt OEM mode, Weimar is based on the long-term, planning the first intelligent manufacturing base of China’s new force of car manufacturing: Wenzhou factory.The base covers an area of 648,000 square meters, with a total investment of 2.5 billion YUAN. The overall planned capacity of the factory is 100,000 units per year.At that time, Weima Wenzhou has a systematic plan for energy conservation and environmental protection, specific to each link: in the non-production link: its refrigeration unit energy saving rate of 10%, can apply for 10% of the national energy rebate subsidy;Industrial energy-saving ceiling fans replace traditional industrial wall fans with energy saving rate of > 50%.The workshop sets up post air supply according to the workers’ station, without full air conditioning system, economic and energy saving;The refrigeration station is equipped with computer room group control, which automatically adjusts the operation parameters of the refrigeration unit according to the terminal load change and energy saving control;In addition, 387 smart pure electric vehicles are used in the plant area, with an annual emission reduction of 822.5 tons (15,000km) and carbon reduction of more than 12,338 tons (12,338 tons) in the whole life cycle (15 years).The fuel forklift trucks in the factory area are also replaced with battery forklifts, saving energy and protecting the environment.In the production process, Weimar from stamping, welding, painting, assembly, automobile manufacturing four major processes, each link to implement energy conservation and environmental protection.Stamping workshop: it mainly produces large and medium-sized stamping parts of EX5 car body, such as side panels, wing panels, four doors and two covers.Its highlights include: the lubrication system of the press adopts the thin oil circulation lubrication system with automatic fixed point, quantitative and timing. The whole line of the press adopts the continuous mode with energy feedback unit, saving more than 30% energy compared with the ordinary discontinuous line.Body shop: at present, the automation rate of the main line in the body shop of WEimar has reached 100%.Spot welding workstation with a full set of self-designed and manufactured tooling, compared with ordinary robot welding, efficiency is increased by 30%, power consumption is reduced by 20%;Painting workshop: Weima adopts B1B2 water-free paint process for automobile painting.Its highlights include, drying exhaust gas TNV incineration treatment, spray paint exhaust gas through the runner after concentration RTO treatment;All the paint is automatically sprayed by robots to improve the utilization rate of paint.Using dry paper box paint mist collection system, no waste liquid waste residue generation;Final assembly workshop: The final assembly Production department of Weima Automobile realizes the co-linear flexible production of two platform models.The glue coating process driven by robot vision technology realizes real-time glue coating quality detection and adaptive tuning, the one-time quality qualification rate is > 90%, and energy consumption is reduced through efficiency.It is worth mentioning that in addition to energy saving, Weima Wenzhou plant also generates its own energy.The actual installed capacity is 8.7MWP, and the utilization rate of the plant is nearly 80%.So far, the total power generation is nearly 30 million KWH (27801760 KWH) = 10,000 tons of standard coal (11127T) + 100,000 tons of clean water (111269t) + 26652T emission (27733.9tCO2), which can provide daily electricity for 41,900 permanent residents in Oujiang Estuary of Wenzhou for one and a half years (511 days).This is a very forward-looking innovation that helps the country reduce its energy consumption while taking on the responsibility of renewable energy.Rammasun distributed photovoltaic power generation systems and wenzhou factory, Ma Huanggang also in accordance with the standards of the same plant construction, which is a new power one of the few building cars both smart base (including the vehicle factory, the battery pack factory, etc.) and the representation of the new energy automobile production qualification enterprise, to become China’s future intelligent new energy automotive industry park of 4.0.Under the background of “double carbon”, all new energy vehicles are trying to reduce emissions as a whole. As a representative of new forces in China, WEIMar has set an example for domestic enterprises.In the face of the same topic, “across the ocean” Volkswagen, Tesla and other foreign enterprises, also provide a new “solution to the problem”.In Shanghai, Tesla built its own gigafactory. Tesla developed 4680 cells by itself, and its production line can reduce energy consumption by 70% and waste recovery rate by 96%.In addition, Tesla independently developed the production and manufacturing control system, which is applied to vehicle manufacturing, battery workshop, motor workshop, etc., with human-computer interaction, intelligent recognition and traceability functions.At the same time, every corner of the automated production line has covered the high reliability of the industrial network, for equipment automation, production equipment wireless connection, production information data collection, intelligent decision-making to provide perfect network services, improve work efficiency, in order to achieve the purpose of energy conservation and emission reduction.The MEB plant of Volkswagen also provides another reference for the green transformation of traditional automobile enterprises.Through 27 environmental protection and energy saving technologies including photovoltaic, cogeneration of heat and power and waste heat recovery, it has reduced five key environmental indicators of energy, water, carbon dioxide, volatile organic compounds and waste by 20%.In the paint workshop, SAIC Volkswagen MEB plant also uses many energy-saving and emission reduction technologies.For example, in the paint pretreatment process, SAIC Volkswagen MEB plant uses silane film technology to replace the traditional zinc-based phosphating technology.Basically no waste residue, water consumption and electricity consumption are lower.To sum up, In terms of energy conservation and emission reduction, Tesla gives full play to its technical fanatic characteristics and focuses on technological innovation.Volkswagen, on the other hand, relies on its years of manufacturing experience to innovate in manufacturing.Weimar is based on the long-term, in the overall layout at the same time also pay attention to details.As mentioned in the beginning, the “dual carbon” strategy is short of time and heavy task, and there is no unified standard answer.But as front-runners at home and abroad, Weimar and Tesla do provide a reference for their peers.Only follow the pace of The Times, based on the long-term, in order to compete in the future, in an invincible position.
