At present, the global chip production capacity is tight. The core factor of "core shortage" is still the sudden release of demand side. The global penetration rate of new energy vehicles was only 3.7% in 2020, but it soared by 2.3 percentage points to 6% in the first half of 2021. Specifically, in the first half of 2021, the cumulative global sales of new energy vehicles reached 2.41 million, a year-on-year increase of 170%. Although the base was low due to fashion last year, the sales of new energy vehicles increased steadily.
As we all know, the biggest difference between new energy vehicles and traditional vehicles lies in the different ways of providing power. One uses traditional chemical energy, which has a greater impact on the environment; One uses clean electric energy, is more friendly to the environment, and is more suitable for the current carbon neutral background. New energy vehicles are mainly divided into pure electric power, plug-in hybrid power and extended range, etc. Its power part is mainly composed of battery, motor control and power supply. With the development of motorization and intelligence of automobiles, the demand for semiconductors is greatly increased.
At present, the demand for analog chips of new energy vehicles is mainly driven by electrification and intelligence, such as power system, automatic driving, in-vehicle entertainment, instrument panel, body electronics and lighting. From the application scenario, new energy vehicles include PHEV and BEV, and the powertrain mainly includes motor controller, OBC, DC/DC, BMS, etc. At the same time, the demand of intelligent driving in sensors will also promote the development of analog chip market.
The power domain of new energy vehicle is composed of battery, motor and electronic control, and the system involves many times of electric energy conversion, which requires the use of a large number of analog devices.
Car body domain
Body domain includes body electronics, car safety, comfort control and information communication system; Automobile lighting mainly includes lighting lamps, internal and external signal lamps, etc.
There are mainly car audio system, car multimedia player and display; Vehicle-mounted global positioning system, vehicle-mounted computer, car anti-theft system, parking assistance system, keyless entry system and remote control starter, etc.
With the development of new energy vehicles, related supporting industries have also been driven, such as DC charging piles and AC charging piles; Energy storage, intelligent transportation, car networking, etc.; The development of these related industries has also driven the rapid growth of demand for semiconductors.
