Why are you so excited? In other words, of course, because id.3, as the pioneering model of MEB architecture, is no less than the ancestor of MQB - so I also hope to introduce it into China. However, less than half a year from the original IPO, the overseas media suddenly revealed that id.3 may be "dystocia", which has encountered a series of unprecedented difficulties; coupled with the public's delay in announcing the postponement, did not let me start to doubt? Id.3, as the most advanced electric vehicle of Volkswagen, is it going to be a scrap? Quick reading of key points 1. The originality (design, software, hardware) of id.3 of Volkswagen, 2. Before the official listing, there were countless problems, 3. Delaying the listing of id.3 of Volkswagen, not only consumers, but also the incalculable loss of Volkswagen, 4. Volkswagen devoted itself to the comprehensive use of id.3 Thinking. Is Volkswagen id.3 an electric version of golf? Yes, no, listen to Xiaobian and tell you slowly! Volkswagen hopes that ID3 will become the sales pillar in the era of electrification, just like golf today. But technically, they are totally different. ● Klaus Bischoff, chief designer of the design Volkswagen brand, said: "with id.3, it marks the beginning of the future of Volkswagen. The natural design and absolutely intuitive user experience show a new way of thinking." In the design part, it can be seen from a glance that VW id.3 has completely abandoned the previous popular family design, gathered more innovative designs and new technologies, showing the future design direction of VW, and also proved that its position is no less than that of the beetle and golf; among them, the front face does not have the traditional sense of the middle net, but instead has become a The open grille, coupled with a new LED light belt running through the VW logo and connected to the headlamp groups on both sides, has a strong sense of future as a whole. At the side, a sharp waist line runs through the front and rear door handles from bottom to top, and extends to the tail lamp; the D-pillar design with different colors and textures adds a "playful" flavor to the car; it is worth mentioning that id.3 also uses a petal style hub, which is not only unique in shape, but also more efficient in aerodynamics. When it comes to the tail, the black part spreads from the roof to the tail box cover, with the lightening Volkswagen logo and id.3 brand logo, bringing a full sense of high-level; the tail light groups on both sides are like a flat "P" letter, and the built-in light groups are more exquisite like handicrafts. At a glance inside the car, the interior design of id.3 has changed a lot compared with the traditional fuel car of Volkswagen. The most special change is the design of connecting the electronic gear and the instrument panel. The gear handle is integrated on the right side of the LCD instrument panel, with unique shape. The user can shift by turning the end, and the right side of the instrument panel can also display the current gear. ● hardware id.3 is based on the MEB modular platform developed by Volkswagen for new energy vehicles, so it has a good balance in driving parts and interior space. The electric drive unit of APP 310 is mainly composed of a 150KW (204ps) electric drive permanent magnet synchronous motor with a peak torque of 310nm, which is assembled on the rear axle together with 1-speed and motor controller. In addition, the stator of the motor adopts the flat hairpin winding technology, which can not only improve the power density of the motor, but also effectively reduce the volume of the drive motor. In order to save space, the high-voltage flat battery pack of id.3 is cleverly integrated in the middle of the chassis, and the lightweight liquid cooling system is added. It provides three battery capacity specifications (wltp condition endurance is 330km, 420km and 550km respectively) of 45kwh, 58kwh and 77kwh, and supports 100kW fast charging. In this charging mode, it can provide 290km in 30 minutes, with remarkable achievements 。 In addition, Volkswagen also provides an eight year or 160000 km warranty for the battery pack of id.3, which proves Volkswagen's confidence in the battery technology of id.3. However, due to the rear mounted motor, Volkswagen also integrates the air conditioning compressor, steering motor and electronic equipment control in the front to achieve the perfect body weight; at the same time, thanks to the fact that most of the assembly is also integrated in the chassis, id.3 has a unique low center of gravity design, which can achieve a higher driving limit. (the current golf operation has been envied by Xiaobian, and now I'm looking forward to id.3!) ● why is Android Software so much better than iPhone in hardware, but the user experience is still far away? The answer is very simple, because software teaching! This time, VW id.3 also plans to polish its software, so it specially developed a set of "VW. OS" vehicle system. The system simplifies the original 70 plus and ECU into a high-performance vehicle computing platform (HPC) with 3-5 cores of the whole vehicle, and controls these HPCS in a unified way. It uses OTA online upgrade (similar to) and Volkswagen cloud to achieve real-time iterative upgrade of functions and systems, just like a mobile phone, "every day" has new discoveries. (for someone like me who loves "machine", I can't be better. I will study and brush every day later!) At the same time, the benefits of this "VW. OS" vehicle system are also very intuitive: 1. It reduces the manufacturing cost of the previous complex ECU; 2. The software has a more efficient processing ability; 3. It can support the OTA upgrade; 4. It has a higher adaptation rate with the vehicle hardware developed by itself; 5. It can grasp the voice of the future car by increasing the independent software development rate. "In the future car competition, car software will account for 90% of the car innovation in the future, and VW's approach is to seize the highland of software and try to open up a new era," said Volkswagen CEO DESs. Once we succeed, every ambitious enterprise will follow VW's example and rely on an intelligent and evolvable automobile electronic and electrical architecture for its own automobile products. " The public in the revolution "own" life saw above is not simple id.3! However, a report by the German media "manager magazine" in December 2019 poured cold water on Volkswagen, saying: "Volkswagen id.3 currently encounters a large number of software bugs, so it is expected that Volkswagen id.3 will probably be delayed for 3-12 months." Although VW publicly denied the report in February this year and announced that the first batch of about 30000 id.3 units will be delivered in the summer of 2020, according to a recent Volkswagen insider, "id.3 has not yet reached the standard of mass production." This time, the public and the media actually sing against each other. Who is real and who is fake? Today we will analyze it! First of all, by collecting information from overseas media, we can find that there are two main problems hindering the mass production of id.3: "underlying software" and "European coronary epidemic". ● at present, most of the problems of id.3 reported by overseas media are focused on the constant exposure of bugs in the underlying software, and the progress of bug repair seems to be unable to catch up with the progress of problem discovery. According to the people interviewed earlier, "the core problems of this series of bugs caused by Volkswagen id.3 are attributed to the fact that at that time, Volkswagen was in a hurry to develop the underlying architecture of the whole system, resulting in frequent incompatibility between various modules, which led to the collapse of the whole system." (it's similar to the "blue screen" caused by the software conflict on Windows). In addition, the id.3 software in the initial trial production is commissioned by suppliers such as mainland, so after the problem erupts, it's very difficult for Volkswagen to deal with it in a timely manner, so it must cooperate with suppliers to check one by one, which undoubtedly delays the time to solve the problem. Although after the outbreak of the problem, Volkswagen immediately convened more than 10000 technical experts from the whole group (including Volkswagen, etc.) to solve the problem, communicate with the Engineer in the morning and afternoon every day, and then dispatch technical personnel to dismantle the faulty unit on id.3 in the evening for repair, and then assemble it back. However, in a day, the whole team can find at most 300 system bugs. It can be said that this is not a problem that 10000 technical experts can solve immediately. To repair a system bug, the number of codes to be modified is no less than that of the whole system to be rechecked. At the same time, we need to find a solution. It takes time and effort, as if we are fighting a "protracted war" with bug At the same time, engineers need to further promote the research and development of other functions to ensure the official launch of VW id.3 this summer. (this pressure can be felt even when I just write a small edition.) in addition, according to the overseas media, Volkswagen also plans to deliver the first batch of id.3 to internal employees for long-term monitoring. Before the vehicle is officially delivered to customers, Volkswagen employees will give important feedback to the official. It's not hard for us to understand why id.3 is so difficult. This time, the masses are changing their lives. In an old saying, "the revolution has not yet been successful, and comrades still need to work hard.". For a traditional car enterprise, this time, it will transform a new car building mode, develop a series of auto electronic and electrical architectures that can be upgraded by OTA, and constantly deal with the bug exposed from time to time, using one word to describe "difficult"! ● in addition to the public's own problems, the sudden coronavirus covid-19 also made public id.3 sweat. The global auto industry is suffering the biggest decline since the 2008 economic crisis. It is also said that this is a more serious crisis than the Great Depression of the world economy in 1929. Anyway, there is no doubt that this is the darkest time for the global automobile industry. Novel coronavirus pneumonia was diagnosed in Beijing over 260 thousand hours as of March 24th, 20 cases, including 63 thousand cases in Italy, 46 thousand cases in the United States and 30 thousand cases in Germany. With the rapid spread of the epidemic around the world, many global automakers have to declare factories closed for at least two weeks. Among them, there are more than 100 factories including Volkswagen Group. Overnight, the automobile industry in Europe and America, the source of automobile culture, almost completely stopped. Volkswagen also announced that "the shutdown will be extended to April 19, and all 28 Volkswagen factories in Germany that produce passenger cars, commercial vehicles and spare parts will continue to shut down.". The list of 28 production stops includes the tsviko plant that makes VW id.3. At this time, I can imagine the shadow area of the public id.3's heart: "why is it so difficult to say a good summer listing?" ● the battery capacity is insufficient. A few days ago, we reported that e-tron, the first flagship model of Volkswagen Group, was temporarily stopped in Brussels, Belgium, due to the limited capacity of LG Chemical's power battery factory in Poland, which resulted in the lack of power battery supply. This doesn't remind me whether VW id.3 will also encounter the problem of change? After all, Audi e-tron, as a high margin luxury model, can't guarantee sufficient battery capacity, so what about Volkswagen id.3? If it can't be delivered on time, it will be even worse. For ordinary consumers, if id.3 is delayed in delivery, it's just to pick up the car later. But for Volkswagen, the problem is more than that. ● the biggest penalty from the EU is the huge penalty. According to the regulations of the EU government, from January 1, 2020, 95% of new cars in Europe should not emit more than 95 grams of carbon dioxide per kilometer, and the average carbon dioxide emission of all new cars by 2021 is even more necessary
