SAIC's strategic planning for the power system is entering a new period of development. At the DMH Technology Brand Conference held in Shanghai, SAIC Roewe officially unveiled the "DMH Super Hybrid Technology", marking another important step for the Chinese company in terms of new kinetic energy.
This technology brand conference is one of the series of activities of the 2024 China Brand Day. Jiang Wei, Secretary of the Party Leadership Group of Xinhua News Agency Shanghai Branch and Secretary of the Party Committee of China Economic Information Service Shanghai Headquarters, Zu Qijie, Vice President and Chief Engineer of SAIC Group, Wang Jun, General Manager of SAIC Passenger Car Company, Lian Ping, Chairman of China Chief Economist Forum, and Yao Chunde, Professor of Tianjin University and Deputy Director of the "China Heart" Top Ten Engine Judges, attended the conference and discussed the new breakthroughs in China's hybrid technology and how the new energy vehicle industry can accelerate the cultivation of new quality productivity.
DMH super hybrid technology
As one of the earliest enterprises in China to carry out new energy research and development, SAIC Motor has laid out the field of plug-in hybrid technology in 2010. In 2017, the first-generation EDU hybrid technology won the second prize of the National Science and Technology Progress Award. The DMH super hybrid technology released this time is a new driving force for SAIC's own brand to maintain its long-term competitiveness.
According to SAIC's statement, DMH super hybrid technology has three technical characteristics: modularization, integration and exclusivity. According to the modular design and serial configuration, the system can match different hybrid routes such as PHEV/EREV/HEV through one system, which can cover the driving needs and fuel consumption regulations of different users. The DMH system has a number of technologies such as global thermal management in the energy domain, PICU of the powertrain brain, and coaxial structure of the engine + P1 motor, with software algorithms as the core, and special hardware such as hybrid high-efficiency engines, gearboxes, and long-range batteries to achieve power performance and efficiency indicators.
At present, DMH super hybrid technology has been first installed in the Roewe D7 DMH and Roewe D5X DMH. In the recent extreme endurance challenge, the Roewe D7 DMH overcame adverse factors such as bad weather and finally completed an ultra-long endurance of 1962 kilometers, with an average fuel consumption of 2.8 liters per 100 kilometers.
Qiu Jie, vice president of SAIC Innovation Research and Development Institute and general manager of Jieneng Automobile Co., Ltd., said that in the next three years, the DMH super hybrid technology brand will carry out a series of performance upgrades in engine, gearbox, battery, motor and energy control, including the engine thermal efficiency will break through to 46%, and take the lead in meeting the Euro VII emission standard in China; In terms of transmission technology, the target CO2 emissions of the diesel-electric hybrid route will not exceed 95 g/km, and the plug-in hybrid and extended-range electric routes will adopt a new configuration of dual coaxial scheme; The energy control will continue to be optimized, and the next-generation vehicle energy center concept is expected to be released in 2025.
Launched the SAIC brand
"The launch of DMH super hybrid technology is a 'super fusion' of science and technology SAIC, quality SAIC, and responsibility SAIC, and it is also an important practice to launch the SAIC brand." Zu Bijie said, "At present, SAIC is benchmarking itself to build a world-class enterprise, making every effort to build a trillion-level automobile industry group with global competitiveness and brand international influence, and continuously making the SAIC brand sound by building SAIC with science and technology, quality SAIC, and responsibility SAIC." ”
For a long time, SAIC has adhered to technological innovation as the core driving force and actively laid out forward-looking technology fields. SAIC Motor's R&D platform for passenger cars, SAIC Innovation R&D Institute, has been fully prepared in the fields of forward-looking technology, R&D personnel, and hardware equipment to support the product development of the four major brands of Roewe, MG, Zhiji, and Feifan and overseas markets.
In terms of talent pool, SAIC Innovation R&D Institute is committed to building a R&D team with global vision and competitiveness. Not long ago, Mr. Joseph Kaban, a world-renowned automobile designer, officially joined SAIC, which will further promote the competitiveness and internationalization of SAIC Motor's design.
In the era of fuel vehicles, SAIC Roewe has a good past. With the release of DMH super hybrid technology, the Chinese independent brand will face the competition in the new energy market with a more confident brand image and better product strength. How to create first-class quality through new technologies will become the key to SAIC Roewe to win the reputation of consumers.
