As we all know, in recent years, China has suffered sanctions from the United States in the field of semiconductors, and many domestic technology companies have suffered painful losses, but China is also trying to solve this problem, and recently lasted 7 years, domestic semiconductors have made major breakthroughs, and the first silicon carbide car chip independently developed by China has officially rolled off the production line, which is said to be a chip specially applied to electric vehicles, which can greatly improve the power performance and endurance of electric vehicles, before this technology has been mastered by the West, and now China also has the ability to produce it. Silicon carbide chip: it has excellent characteristics such as bandgap, drift speed, breakdown voltage, thermal conductivity, and high temperature resistance that are several times higher than traditional silicon, and has irreplaceable advantages in extreme environmental applications such as high-power electronics, aerospace, military, and nuclear energy.

Electric vehicles are the use of batteries and motors as a source of power of the car, and the internal combustion locomotive compared to the structure of electric vehicles are very different, they are mainly composed of electronic control systems, motors and batteries three parts, known as "three major pieces", directly determine the performance of electric vehicles, and silicon carbide is a new type of semiconductor material found by semiconductor experts in recent years, compared with ordinary silicon chips, the advantage of silicon carbide chips is that it can withstand greater power, can be more fine control of the current, The electric vehicle's electronic control system is responsible for controlling the current and voltage from the battery to the motor, so as to control the speed of the motor and the acceleration and deceleration of the entire car, the silicon carbide chip is very suitable for use in the electronic control system, as a component to control the current.

The electronic control system manufactured with silicon carbide chips can improve the performance of all aspects of electric vehicles, so that electric vehicles have more powerful power performance and farther endurance, so once born, it has become a hot product, but before this technology has been mastered by a few countries such as Japan, China itself can not manufacture, resulting in China's domestic electric vehicle brands must spend high prices every year to import silicon carbide chip manufacturing products from Japan, and Japanese electric vehicle brands and Chinese brands have a competitive relationship, in order to limit the development of Chinese brands, Japan has long announced a ban on the export of the most advanced silicon carbide chips to China, creating a huge obstacle to the development of Chinese electric vehicle brands.
And the advent of this Chinese product ended this situation, according to Chinese engineers, this Chinese independent research and development of silicon carbide chips in all aspects of the performance is not inferior to Japanese products, and Japan's most advanced performance chips are comparable, but also have a huge advantage in price, with its manufacturing of domestic electric vehicles can not only have more powerful performance, cost and final price can also be greatly reduced, to achieve profits to consumers, now this domestic silicon carbide chip has been officially put into mass production, Several Chinese electric vehicle brands are starting to use it to make new electric vehicles.

In fact, not only this silicon carbide chip, China in recent years in the field of electric vehicles to achieve a considerable number of achievements, for example, in battery technology, a number of domestic electric vehicle brands have developed advanced electric vehicle batteries with independent intellectual property rights, so that their products have a longer range or stronger safety, some Chinese manufacturers of brand production of batteries and even exported to Western countries.
In terms of automotive-grade chips, a group of domestic electric vehicle manufacturers led by BYD have also invested a lot of money in the research and development of domestic automotive-grade chips in recent years, built a series of high-performance products, not only realized the replacement of foreign products, but also successfully mastered the key technologies in their own hands, it can be said that it is the continuous innovation of these enterprises that has made China one of the most powerful countries in the world in the field of electric vehicles.
