Recently, my country's overall automobile sales have shown a slight downward trend. In July, overall automobile sales were 1.889 million, a year-on-year decrease of 4.0%. However, there is a clear flow in this situation. New energy vehicles continue to maintain a trend of rapid growth. In July, the sales of new energy cars were 90,400 and the sales of new energy SUVs were 83,700, an increase of 53.59% and 47.69% year-on-year respectively. . In addition, the Travel Association also released new energy vehicle data for the first half of the year. In the first half of the year, global sales of new energy passenger vehicles reached 720,000 units, a year-on-year growth rate of 32%. Among them, China's sales reached 350,000 units, an increase of 60% year-on-year. The world share of China's new energy passenger vehicles reached 50% from January to June 2018. Capital chasing frantically, round after round of investment opportunities. In recent days, Evergrande Faraday Future Smart Cars have even accounted for recent hot news about future cars. Not only has it ignited the enthusiasm of the entire automotive market, but also made all automotive practitioners look forward to the future of the industry. Automotive electronics is a secondary market directly related to the development of new energy vehicles, and it is also a market that magnetic materials and magnetic device companies have developed in recent years. With the rapid advancement of 5G, wireless transmission, unmanned driving and other technologies, new energy vehicles will also accelerate their development in the direction of intelligence, high frequency, and interconnection, and they will also put forward stricter requirements on automotive electronics. , Electromagnetic compatibility (EMC) has naturally become an unavoidable research and development focus and difficulty of various car companies. A large number of high-voltage and low-voltage power electronic devices are used in new energy vehicles, and EMC may cause errors during operation. If the electromagnetic compatibility performance does not meet the requirements, it will cause intermittent failure or permanent damage of the device. The failure or damage of these key parts may cause the parts to not work normally, and in the worst case, it may lead to a major safety accident of the entire vehicle. EMC is a comprehensive assessment of the electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products, and it is one of the most important indicators of product quality. Wang Zhiwen, member of the Lightweight Technology Department of BAIC Group New Technology Research Institute, believes that compared with traditional cars, the electromagnetic environment of electric vehicles is much more complicated, and the electronic and electrical components in the car occupy a large proportion. The electromagnetic compatibility problem is closely related to the safety of the whole vehicle. Related, the chances of EMC problems are increasing. Wang Zhiwen said that electromagnetic compatibility is a technical problem that will inevitably be encountered in the development of new energy vehicles, which poses certain challenges to vehicle manufacturers. Electric cars use more control, monitoring, display and radio and other electronic equipment than traditional cars. TDK also believes that EMI suppression has become a major problem in the transmission, reception and processing of electronic signals and data. Automotive Ethernet interconnects the various functional modules of modern systems through cables or wire harnesses, and has extremely high signal transmission speeds. However, reliable high-speed data transmission requires both high noise suppression and low data signal attenuation. Because high-speed data transmission equipment, high-speed switches and high-frequency RF equipment occupy the electromagnetic environment, EMC regulations in major global markets are becoming more and more stringent. Global standards bodies have established passive filter specifications, such as the European EN 60939 standard based on IEC 60939, and UL 1283 or MIL-F-15733 applicable to the United States. At present, ferrite cores and high-permeability suppression materials are also being continuously developed to resist radiation noise with frequencies up to 1GHz or even higher. On the other hand, the development of communication technologies such as the Internet of Vehicles, 4G, and 5G has also put forward new requirements for the development of new energy EMC. The above communication methods rely on the transmission of wireless signals, so the electromagnetic compatibility of the vehicle is particularly important. Once the communication frequency is subjected to electromagnetic interference, it will inevitably lead to an increase in the error rate of data transmission or even communication interruption. In addition, wireless transmission technologies such as Bluetooth and WIFI are also technologies widely used in cars under the Internet of Vehicles. Wang Zhiwen believes that one of the key components to solve these problems is the inductance device. For the design of inductors used in EMI devices, people have done a lot of discussions on the selection of magnetic core materials. Choose low-priced silicon steel and iron powder cores, which have poor frequency characteristics and are easy to generate heat, which affects the operation of the switch tube; using conventional high-performance ferrite materials, its saturation magnetic induction intensity and Curie point are low, and it is necessary to increase the size of the magnetic core. Increase the air gap; using permalloy iron core, the cost is higher, and the cost performance is higher when used under high current conditions, because the working frequency band of this kind of inductor is in the kHz level. At present, nanocrystalline materials are suitable for use in this frequency band, and are increasingly recognized and adopted. The thickness and resistivity of the thin strip of nanocrystalline soft magnetic materials determine its best application frequency range in the kHz band, which is exactly the same as the frequency band of power electronic converters in current new energy vehicles, and has broad application prospects. Foshan Zhongyan Amorphous is an enterprise engaged in the production and R&D of nanocrystalline soft magnetic materials. Its chairman Shen Xubin confidently said, “Zhongyan’s solution has become the first choice in the automotive field. In China, we only need to talk about filter inductance and common mode in the automotive field. For EMI and EMC, China Research Institute is definitely the first choice.†It is reported that China Research Institute has already cooperated with Geely, Yutong, SAIC, Dongfeng and many other vehicles. Shen Xubin said that in the future, new energy vehicles will be the company's key positioning market. The reporter interviewed Jiangxi Dayou Technology and other companies engaged in the research and development of amorphous and nanocrystalline production, and they all said that new energy vehicles are the top priority of the company's development at present and in the future. In fact, the development of new energy vehicles has indeed brought profound changes to the development of magnetic components and soft magnetic materials companies. With the rapid development of new energy vehicles and the more and more widespread use of electronic technology in modern automobiles, it provides an encouraging application field for the magnetic components and magnetic materials industry. For example, one of the core components of an environmentally friendly and energy-saving hybrid car is a DC-DC converter for power conversion, which uses a high-performance, wide-temperature, low-loss ferrite core similar to TDK PC95, which is a recent magnetic component and magnetic material One of the iconic achievements of the industry's technological progress has also provided this industry with a promising high-end market in the future. At present, many mature models of Japan's Toyota and Honda have been sold globally. In recent years, most companies in magnetic components or magnetic materials have focused on new energy vehicles during their transformation, and consciously moved closer to new energy vehicles. Wang Qiang, chairman of Mianyang Jingweida Technology Co., Ltd., believes that automotive magnetic materials and applications have their particularities. One is that they have a fast quantity and a relatively large value; and the other is that the technology content is relatively high, which is an opportunity for the transformation of magnetic enterprises. Wang Qiang told reporters that due to the higher requirements in the automotive field, the company has invested a lot in high-end magnetic components, and the return it has achieved is recognized by large automakers such as BMW and Mercedes-Benz. It is understood that the application of Sunlord Electronics in the field of automotive electronics has continued to develop with the changes in the market. The product supply has gradually cut into the vehicle safety control system from the initial on-board audio-visual system, providing a variety of radio frequency devices for the electrification and intelligentization of automobiles. , Electronic transformers, power inductor products. Sunlord Electronics is also confident that it will benefit from technological innovations in the direction of smart driving and new energy vehicles. The automotive electronics field has become an emerging application market for electronic components. In the future, the cost of automotive electronic components will account for the cost of the entire vehicle. Upgrading, the market space is broad. At present, it has become a qualified supplier of many world-renowned automotive electronics customers such as Bosch and valeo. In the future, automotive electronics will become one of the six major application markets for Sunlord's electronic products. Shenzhen Kedajia Electronics also provides suitable integrated inductors, high current inductors, digital power discharge inductors, magnetic rod inductors, I-shaped plug-in inductors and other inductance supporting solutions for manufacturers in various fields including automotive electronics. In addition, Zhaotian Magnet has also attracted cooperation with automobile manufacturers such as BYD and Yutong Bus.
