In the global TOP5 semiconductor suppliers, there have been many many years of history, especially in the automotive field, more than 30 years of product experience.
In the development trend of electricalization and dataization of automobiles, in 18 years, traditional automotive electrical appliances including engine parts accounted for 70% of our business, and electrical and digital things accounted for 30%. In the next 5 years, the development rate will be very fast. In terms of proportion, traditional automotive electronics and modern relatively new digital things will account for 50%.
What are the specifics of electrification? A charging system and power system related to new energy vehicles, as well as intelligent assisted driving, such as machine vision, radar, and body network, including the network inside and outside the vehicle. There is also high-precision positioning.
In electric vehicles, the most important thing is the battery. The voltage is generally about 400-800 volts. It needs to supply power to other body parts through the battery. From 400 volts to 800 volts, Zhunhua to some power required by the tractor, to In the end, it becomes a three-phase voltage driving real tire driver, and a battery management system, the biggest role of which is to maintain the long-term working state of the battery.
At the same time, there are 12-48 volt systems in some traditional cars, all of which are converted by 400-800 volt systems. It also includes a charging system, which comes with a car, and also charges the body through external 380, 220. One point that many new energy vehicles are criticizing is that the charging time may be one hour or half an hour, but the use of silicon carbide technology will greatly shorten the time, which may be 6-7 minutes.
Here are some things related to the digitization of cars.
Digitization means that automotive design is becoming more and more complex. It has now exceeded 100 million lines of code, about 15 times as many as airplanes, but it is still growing and is a linear growth process.
Investment in intelligent driving has accounted for 50% of the entire automobile research and development investment, and this trend is still growing.
Regarding big data-related things, investment in this field has exceeded 100 billion U.S. dollars, and many companies are not from traditional car manufacturers, but more from non-automotive companies.
Briefly introduce current trends:
In the future, the concept of "domain" will be adopted, with some new requirements and higher processing power. There are many nodes in each domain. The benefit is that the vehicle body supports external communications more strangely, as well as very high network communication functions. .
The automobile is still the most important industry of ST in the entire chip industry. We will invest more funds and manpower to create more good products in the automobile to serve customers in various countries.
