On November 18, 2020, the "2020 Beijing International Road Transport, Urban Public Transport, Tourist Passenger Vehicle and Parts Exhibition" kicked off in the new hall of China International Exhibition Center (hereinafter referred to as Beijing Road Transport Exhibition). BJJJ Electric Technology Group held the "High-power Vehicle Silicon Carbide Controller Product Release Conference" on site.
The high-power silicon carbide controller is the crystallization of BJJJ years of research and development. With the rapid development of new energy commercial vehicles, passenger cars have entered a period of technological upgrading, and heavy and medium trucks have become new growth points. Numerous arguments have proved that to solve the fuel and emission problems of commercial vehicles, a combination of various electrification technologies is necessary; whether it is pure electric, fuel cell or hybrid power, efficient and high-power electric drive systems are required.
The popularization and application of third-generation semiconductor silicon carbide power devices is an inevitable trend in the development of electric drive systems. If the advantage of silicon carbide in the passenger car market is reflected in performance and efficiency, the advantage in the commercial vehicle market is in efficiency. Passenger cars and trucks are production tools, and the importance of economy is much higher than that of the consumer market. BJJJ's silicon carbide controller can fully utilize the efficiency advantages of silicon carbide through advanced design and excellent electronic control software, combined with BJJJ's motor and transmission technology.
High power silicon carbide controller
The silicon carbide controller introduced by BJJJ this time has a power range of 300 kilowatts up to nearly 600 kilowatts. According to the different working conditions of the vehicle, the energy saving rate relative to the silicon-based controller is 3% to 6%, and continues Maintaining the traditional advantages of the BJJJ controller, such as high functional safety level, free towing, safety down the mountain, etc., so that BJJJ maintains the leading technology in the electric drive industry.
It is reported that a customized version of this series of silicon carbide controllers has just won the batch designation of Volkswagen’s commercial vehicle group and TRATON Group. It will be used in large quantities for TRATON Group’s buses and heavy trucks in the global market, including German MAN and Sweden Well-known brands such as Kania. After more than a year of competition with top suppliers in Germany, Japan, and the United States, BJJJ won this order. After the product goes on the market, it will be mass-produced continuously for many years, the largest single commercial vehicle product order in BJJJ history.
BJJJ has always been the industry leader in China's new energy commercial vehicle market. BJJJ's electric drive products have already been widely used with world-class commercial vehicles in China, the United States, Europe, and Australia. Since 2014, BJJJ has sold a total of 110,000 sets of electric drive systems for commercial vehicles, with a cumulative mileage of 12 billion kilometers and a cumulative number of 11 million kilometers per day. While maintaining the current domestic technology and market leadership, it has become a rare enterprise that pushes China's technology accumulation to the global market and transforms China's advantages into global advantages.
