Four national standards including electric vehicle charging interface were officially released

Time of issue : 2020-12-10

The reporter learned from the Ministry of industry and information technology last week that four national standards, including electric vehicle charging interface, have been approved and issued by the "national standard announcement of the people's Republic of China No. 21, 2012" a few days ago, and will be implemented from March 1, 2012.

They are: connecting devices for conductive charging of electric vehicles Part 1: General requirements; connecting devices for conductive charging of electric vehicles Part 2: AC charging interface; connecting devices for conductive charging of electric vehicles Part 3: DC charging interface; and communication protocol between off board conductive charger and battery management system of electric vehicles.

Relevant experts said that the release and implementation of the four national standards of electric vehicle charging interface and communication protocol will provide important technical and standard support for the construction of electric vehicle infrastructure, which is of great significance to improve China's new energy vehicle standard system, promote the demonstration pilot of new energy vehicles, and promote the coordinated development of China's new energy vehicles.

After the Ministry of industry and information technology issued four national standards, such as electric vehicle charging interface, the State Grid Corporation of China (SGCC) released on its official website in-depth regulations covering the engineering design contents of three types of electric vehicle battery charging and replacement power stations, including battery replacement station, battery distribution center and battery distribution station.

State Grid said that the release and application of in-depth regulations on three types of engineering design content is conducive to the construction of lean, standardized and standardized electric vehicle intelligent charging and swapping network, and is conducive to promoting the development of electric vehicle industry.

According to a source, the State Grid Company plans to invest more than 20 billion yuan in the development of electric vehicle charging facilities during the 12th Five Year Plan period.

Facilities construction standards first

According to the State Grid Company, the in-depth regulations cover three types of electric vehicle battery charging and replacement power station projects, including battery replacement station, battery distribution center and battery distribution station, and standardize the design and construction requirements of process flow, equipment selection, plane layout and monitoring system for battery charging, transfer and replacement of different projects.

On December 27, the Ministry of industry and information technology (MIIT) just released four national standards, including "connection devices for conductive charging of electric vehicles Part 1: General requirements" and Part 2 (AC charging interface), which are required to be implemented from March 1, 2012.

However, there is still a debate about whether the charging mode of electric vehicles is charging or changing. Some analysts pointed out that the current electric vehicle industry is facing two development bottlenecks: the sales of "complete vehicle with battery" of electric vehicles will increase the price of complete vehicle due to the high price of battery, which will affect the sales; the investment per unit area of traditional charging infrastructure is expensive, which is difficult to sustain the development, which will affect the popularity of electric vehicles.

State Grid Corporation of China (SGCC) pointed out that compared with the cost, charging efficiency, battery maintenance and circulation management, and the impact on the grid and users, the comprehensive performance of the fast switching mode is the best. Therefore, Liu Zhenya, general manager of State Grid Corporation of China, set the basic adjustment of charging facilities at the 2011 work conference. The basic business model of State Grid electric vehicle charging and swapping station is determined to be mainly power exchange, supplemented by plug-in, centralized charging and unified distribution.

This time, the design content of electric vehicle charging and swapping power station project released by state grid also mainly serves the swapping mode. According to the introduction of State Grid, the battery replacement station, battery distribution center and battery distribution station constitute the service network for efficient and fast power supplement of electric vehicles. The standardized design and construction of the three projects will reasonably solve the problems that the current battery technology does not support fast charging, the development of the electric vehicle industry is limited due to the imperfect service network, and the distribution network can not withstand large-scale random charging, The reasonable development mode of electric vehicle charging and

TDK: adapt to new market demand

Time of issue : 2020-12-10

Editor's note: the 13th high tech fair was recently held in Shenzhen. The fair is also known as the most popular "electronic components, materials and assembly Exhibition" in China. Japanese manufacturers with outstanding performance in this field made a wonderful appearance at the exhibition, comprehensively demonstrating that they have achieved miniaturization, integration and intellectualization of products through innovation in materials, design and technology, and constantly meet the needs of communication, communication and communication Consumer electronics, automotive electronics, Internet of things and other applications. This paper selected some representative enterprises to report.

In recent years, TDK, which started with ferrite materials, not only develops its material advantages, but also extends its tentacles to a wider range of hot application fields. With the theme of "technology enriches the earth, society and the future", TDK shows the products and solutions in the three fields of mobile communication, automotive electronics and environmental energy.

Realize miniaturization and intellectualization

TDK is the first to show the nano scale thin film processing technology, which makes capacitors and other devices miniaturized and thin. According to the exhibition staff, its metal film capacitor has the characteristics of small volume and low equivalent series resistance, which can be used for 100000 hours or more. Its self-healing ability makes it safer, and is mainly used in smooth filtering circuits such as wind power, solar energy and industrial converters.

With the touch screen almost dominating the smart phones and tablet computers, the market capacity of capacitive screen keeps rising, and the ITO transparent conductive film displayed by TDK can be said to be in good luck. According to the exhibition staff, one kind of capacitive screen is glass, the other is film. In contrast, film has more advantages, light and will not be broken, and now it is used more and more. TDK's ITO transparent conductive film adopts TDK's unique ultra-fine coating technology, which can achieve high transparency and low resistance. At present, it has been adopted by customers in Japan, and this year it will focus on the promotion in the Chinese market.

With the increasing attention of the market to wireless charging products, TDK also began to make efforts. Tan Qiang of Shenzhen Branch of Dongdian chemical (China) Investment Co., Ltd. mentioned the advantages of TDK: first, TDK starts with magnetic materials, which can be very thin. The thickness of the receiver is only 1.0 mm, and its own heat is less than 10 degrees. The second advantage is the soft magnet. The third advantage is that the conversion efficiency is more than 70%. It needs to be designed and developed according to customer parameters, mainly considering the matching of power control unit, circuit and coil in the design of mobile phone. The future development lies in: first, it can realize charging anytime and anywhere; second, it is non-contact; third, it can provide more power to realize on-board charging.

In the on-board field that TDK focuses on, it shows the temperature sensor, current sensor, IGBT, etc. of automobile air conditioner supporting HEV, PHEV, EV, etc. According to Yang Liming of TDK China general business department and automotive electronics business department in South China, the temperature sensor not only has a complete range of products, but also has excellent moisture resistance and quick response with resin sealed NTC thermistor, and its shape can be customized. In terms of IGBT, the design difficulties are: improving leakage inductance; in terms of size, TDK has high requirements and has its own core technology, which can achieve the required size; with special design, the winding distance can be limited to prevent affecting the work of other components. According to different outputs, such as 4-way and 5-way, 6 IGBTs are generally required, and 3-4 IGBTs are generally required for low-end. At present, there are customer applications in Japan, and it is still in the stage of technical discussion with customers in China. In addition, the newly developed magnet fb13b used in automobile motors is only 1 / 4 of the size of the previous generation products, which can also lead to lighter and more fuel-efficient automobiles.

Embedded substrate lifting packaging technology

It is worth mentioning that the sesub (embedded semiconductor substrate) displayed by TDK is a great improvement to the current flip packaging technology. The thickness of the substrate can be reduced to 300 μ m when a 50 μ m high integrated circuit is embedded. It allows ASIC and a large number of input and output line controller chips directly embedded in the substrate layer, can not be embedded in the substrate can be installed on the top of the multilayer substrate. In this way, SIP can achieve smaller size. At the same time, the product has good
