Introduction: From the changes in the automotive industry, we can initially see the importance of chips, then, chips on the development of the automotive industry, what is the specific important impact?
As of Oct. 10, the global Auto market had lost 9.345 million units of production due to chip shortages, an increase of about 250,000 units from the previous week, according to data compiled by Auto Forecast Solutions, a global automotive consultancy. Of that, 13,000 units, or about 5.2%, were cut in China. As can be seen from the data, chip is the core technology of automobile system, the shortage of market supply has affected the sales of automobile industry.
From the changes in the automotive industry, we can initially see the importance of chips, then, chips on the development of the automotive industry specific what is the important impact?
First, compared with consumer electronics chips, automotive chips have higher requirements in terms of service life, working environment and specification standards. The development cycle of chips is long, difficult and requires the most stringent industry self-knowledge certification.
Secondly, the main application in the automotive system is the car gauge chip chip will be divided by function, car gauge chip can be divided into functional chips, power semiconductor and sensor chip three categories. Among them, power semiconductor including IGBT, field effect transistor (MOSFET) and power management chip, accounted for about 40% in gasoline vehicles, accounted for 50% in new energy vehicles, is the most scarce at the same time the most potential for growth of the chip. Among them, IGBT, as the dominant power device of new energy vehicles, is known as the CPU of the power electronics industry, accounting for about 7%-10% of the vehicle cost, second only to lithium battery, can adjust the voltage, current, frequency and phase of the circuit according to the signal instructions, in order to achieve the purpose of precise control. It can be simply understood that IGBT is the ideal switching device in power electronics industry.
Excellent for new energy vehicles, IGBT switch features can be ac/dc conversion, convert the voltage and frequency conversion several core function, when the electric vehicle charging, converted to direct current (dc) by IGBT to external power supply, at the time of electric braking, through the IGBT transform dc into ac motor used in ac, accurately adjust voltage and frequency at the same time, Drive an electric car. The acceleration capacity, maximum speed and energy efficiency of a trolley car mainly depend on the performance of the power devices of the vehicle, so IGBT is widely used in electronic control, on-board air conditioning, charging pile inverter three subsystems.
Intelligent development is rapid, chip is the top priority, it can be said that to master the profound chip technology is to master the right to speak in the field of science and technology. Therefore, not only in the automotive industry, any intelligent equipment (such as smart phone, intelligent furniture, intelligent security, etc.) can not do without the role of chip, chip development has become the focus of people’s increasing concern. At this year’s Cloud Computing Conference, Alibaba officially released its own cloud chip E-Ten 710, which is an important step for Ali Cloud to promote the strategy of “one cloud and multiple cores”. It is also ali’s first CPU chip born for cloud, which will deploy applications in Ali Cloud data center. From this point of view, the future of chip development is worth looking forward to!
The progress of key technology is the sea of stars that countless enterprises pursue endlessly.
The progress of science and technology cannot be separated from the development of the underlying key technologies. How to make the key technologies have better performance is the direction of the endless pursuit of science and technology enterprises. SaaS system (software and service), as the key technology of Internet technology development and application in the new era, is a completely innovative software application model that began to rise in the 21st century. It defines a new delivery mode, making software further return to the nature of service. SaaS changes the traditional way of providing software services, reduces the large amount of initial investment required by local deployment, and further highlights the service attribute of information software.
The test of a successful website is its stability, security and speed, and the foundation of all this depends on its underlying application infrastructure. [AliYun Website] is a standardized online delivery SaaS system based on cloud computing. It integrates the full set of aliyun cloud computing resources and is equipped with Aliyun server, so you can directly use Aliyun services without extra payment. Provide aliyun self-developed cloud shield security services, maximize the protection of the website, effectively resist malicious attacks, to ensure that the website provides services for users; Standard global CDN network acceleration service, to ensure fast opening of the website.
