On December 26, the second CRRC electric drive independent innovation Technology Summit Forum opened in Zhuzhou, Hunan. Experts from China Automobile Industry Association, Huazhong University of science and technology, FAW Group and other institutions, universities and enterprises discussed the development trend of new energy automobile industry, electric drive, power devices, new automobile materials and other cutting-edge technologies. At the meeting, CRRC electric drive industry alliance for passenger cars was awarded a license and issued a declaration. On the same day, CRRC Zhuzhou Crrc Times Electric Co.Ltd(688187) announced that it had successfully achieved an annual output of 100000 electric drive systems this year. Among them, the c-power 220s, the first high-power electric drive based on self-developed silicon carbide in China, hatched by its C-car platform, was officially offline, and the efficiency of the electric drive system was up to 94%.
Electric drive system is one of the “three electricity” systems of new energy vehicles, and it is also an indispensable core component. It is known as the “core” of vehicles. Zhuzhou Crrc Times Electric Co.Ltd(688187) the self-developed new c-power 220s electric drive system is made of the third generation semiconductor material silicon carbide. It is reported that silicon carbide is one of the ideal materials for making high-temperature, high-frequency, high-power and high-voltage devices. The solution based on silicon carbide can make the system more efficient, lighter and more compact. For example, the c-power 220s high-voltage silicon carbide electric drive system with silicon carbide technology has the advantages of high system power density, low system loss and strong endurance ability. Its system efficiency can reach 94%, which can meet the needs of high-frequency, fast charging, long endurance and high safety of current new energy vehicles. It is widely suitable for high-end cars, SUVs and other models, bringing more safety, efficiency and Energy saving driving experience.
In recent years, the global new energy vehicle industry has entered a new stage of rapid development, and high-performance electric drive system has become a “required course” in the industry. CRRC Zhuzhou Crrc Times Electric Co.Ltd(688187) inherits the key core technology of China’s high-speed railway. After seven years of independent development, it has established two production and R & D bases in Zhuzhou, Hunan and Wuxi, Jiangsu, deeply engaged in the research of automobile electric drive system, created a perfect upstream and downstream key industry chain of electric drive industry, and can provide comprehensive intelligent solutions.
