In the past, about 500-600 chips were generally needed to manufacture a traditional car. With the continuous development of the car industry, the current car is gradually shifting from mechanical to electronic. Cars are becoming more and more intelligent, so the number of chips required will naturally increase. It is understood that the average number of chips required for each car in 2021 has reached more than 1,000.

In addition to traditional cars, new energy cars are the "big chip buyers". This kind of car requires a large number of DC-AC inverters, transformers, converters and other components, and the demand for semiconductor devices such as IGBTs, MOSFETs, and diodes has also increased significantly. A good new energy car may require about 2,000 chips, and the demand is very alarming.

Li Shaohua, deputy secretary-general of the China Automobile Industry Association, pointed out that the current chip planning of the global semiconductor industry is between US$300 billion and US$400 billion. Among them, automotive chips are about 40 billion US dollars, accounting for less than 10%, which will obviously create a vulnerable situation for auto companies when scheduling production or vying for orders.

From the perspective of technical requirements, car-grade chips really make most chip companies daunting. Consumer electronics chip technology iterates very quickly, and car-grade chips are almost all technologies more than ten years ago, but although the technology is "outdated", the threshold has not dropped. On the contrary, automotive-grade chips have high requirements on performance indicators, service life, reliability, safety, and quality consistency, which are difficult for consumer electronics chips to resist.

Compared with consumer chips and general industrial chips, the working environment of automotive chips is even harsher: the temperature range can be as wide as -40°C~155°C, high vibration, dusty, electromagnetic interference, etc. Due to personal safety issues, car chips have higher requirements on reliability and safety. The general design life is 15 years or 200,000 kilometers. "Car-grade" chips need to pass a rigorous certification process, including reliability standards AEC-Q100, quality management standards ISO/TS 16949, functional safety standards ISO26262, etc.

The high standards, strict requirements, and long cycle of automotive-grade chips have repeatedly raised the entry threshold. This has directly led to the fact that only chip companies with strong comprehensive capabilities or vertical integration capabilities and the ability to maximize their design advantages can include automotive-grade chips in the production list. Looking at the world, there are only a few car-grade chip companies such as NXP, Infineon, and Siemens, and there are too many monks. This is another reason why the supply of car chips is in short supply.

my country is working hard to establish a complete innovation ecology of the automotive chip industry to solve the shortcomings of my country's automotive industry in the future development. Among the domestic car companies, BYD, SAIC and many semiconductor companies have successively entered the field of car-level chips.
