I don't know if you have found a problem, that is, many foreign car companies have a chip shortage last year, but most of the car companies with independent brands do not have such a problem. Of course, we must admit that the sales of independent brands and foreign car brands still have a considerable gap, but we seem to rarely hear about the lack of chips in Wuling, Great Wall or Changan cars.
Because China's industry is relatively complete, and the production efficiency is high, coupled with the domestic epidemic has been effectively controlled, and most of China's car companies are produced by themselves, the ability to develop vehicle-grade chips, so we can see that Chinese car companies are not too affected by chips. It is for this reason that in November this year, BYD climbed the sales throne of domestic car companies with good sales.
In addition to the car-grade chip, another key technology in China has also been overcome during this time.
First of all, let's clarify a logic, we charge the electric car, what is the charge? In fact, we charge high-voltage alternating current, and then convert it into low-voltage direct current to power the battery. However, direct current can not directly drive the new car, it needs to convert the direct current into a constant frequency and constant voltage of alternating current, the motor can be used. Simply put, from DC to AC requires a device, that is, an inverter. The efficiency and sophistication of the inverter directly affect the speed and efficiency of the new car. It can be said that the inverter is similar to the function of the gearbox in the fuel vehicle, and the importance of efficiency to new energy vehicles is self-evident.
In fact, our independent brand has always had an inverter, but the strength is very weak, and if you want to obtain a higher mileage and a higher discharge efficiency, you generally need to purchase with foreign related enterprises. This brings two problems, the first is that the cost of procurement will increase, and eventually passed on to the head of consumers, and the more critical problem is that it may be stuck in the neck of foreign related enterprises. To put it more seriously, it may directly "suffocate" the independent brand new energy vehicles, which is extremely unfavorable for the development of the independent brand new energy automobile industry.
The good news is that during this time, China has successfully developed a domestic silicon carbide inverter, compared with foreign related products, its performance is more excellent, the conversion efficiency is higher. And because of the use of a new silicon carbide material, it can carry a larger current, but also more resistant to high temperatures, and the conversion efficiency is quite high, in many key parameters and indicators than foreign products of the same level is better, and this key technology has begun to be assembled into many new energy vehicles. If the future mass production, then the price of new energy vehicles will be further reduced, which is a real and visible benefit for our people.
I have to say that in recent years, the speed of development of our own brands has become faster and faster, and many key technologies are gradually being overcome. I think it was very uncomfortable for us to fall behind in the field of fuel vehicles, the engine purchased from Mitsubishi, the gearbox purchased from Aisin, and foreign manufacturers did not adapt to you at all. So at that time, we can also see that the fuel consumption of many car brands remains high, and the gearbox is seriously frustrated, in fact, it is not that the manufacturer is incompetent, but the supplier is too strong.
Finally, the above-mentioned silicon carbide inverter, whether it is material or design, is 100% made in China. Is there anything you'd like to say about that? Welcome to leave a message.
