Super integration shows strong strength SAIC Roewe ushered in the spring of plug-in hybrid
As the most powerful automobile group in China, SAIC has been deeply engaged in plug-in hybrid technology for many years. As early as 2010, SAIC Motor made a forward-looking layout in the field of plug-in hybrid technology, and regarded it as a technology worthy of long-term investment. In 2017, SAIC's self-developed first-generation EDU hybrid technology won the second prize of the National Science and Technology Progress Award, which was not only the only automotive project among the award-winning projects that year, but also the first time that the new energy technology won the national science and technology award.
Thanks to SAIC's in-depth self-research on the core technology of the powertrain, SAIC will also exceed 46% in terms of engine thermal efficiency, a key indicator that affects the performance of the hybrid system. After long-term technology accumulation and market verification, the DMH super hybrid technology released at this conference has reached a higher level of integration and intelligence, which is a new driving force for SAIC's own brands to maintain long-term competitiveness.
According to reports, DMH super hybrid technology has three technical characteristics: modularization, integration and exclusivity. At the same time, the system has the industry's first "energy domain" global thermal management, powertrain brain PICU, engine + P1 motor coaxial structure and other leading technologies, with software algorithms as the core, matching special high-efficiency engines, gearboxes, long-range batteries and other special hardware for hybrids, "both soft and hard". Achieve hyper-convergence to achieve the highest performance and optimal indicators.
Yao Chunde, a professor at Tianjin University and deputy director of the "China Heart" Top Ten Engine Judges, analyzed that the DMH super hybrid system innovatively improves the off-axis P1 motor to a coaxial structure for the current mainstream P1+P3 hybrid configuration, which greatly improves the transmission efficiency and optimizes NVH performance, making the whole system more efficient and the driving experience smoother and quieter. At present, DMH super hybrid technology has been first installed in the "long-range super-hybrid cloud-sensing car" Roewe D7 DMH and the "long-range new mainstream hybrid SUV" Roewe D5X DMH, and the product strength has been widely recognized by users and professional media. Not long ago, the Roewe D7 DMH challenged the 2000km limit range on behalf of its own brand B-class car, and finally overcame the impact of bad weather to complete the ultra-long range of 1962km and the average fuel consumption of 2.8L per 100km, realizing the transformation of technical value from technical strength to scene application, showing the strength of Chinese brands to break through the "endurance myth" of Japanese hybrids.
"At present, hybrid technology is blooming, products are emerging in an endless stream, and user acceptance is getting higher and higher, and some data predicts that by 2025, pure electric and plug-in hybrid will appear 1:1 situation. The spring of plug-in hybrids is already around us. Lu Yong, deputy general manager of SAIC Passenger Car Company, executive vice president of SAIC Innovation Research and Development Institute and executive deputy director of the technology center, said. At the time of the rise of the domestic plug-in hybrid market, SAIC Roewe has obviously ushered in an opportunity with the blessing of the DMH super hybrid system.
The technology will break through again with the DMH super hybrid system and launch the SAIC brand
Under the wave of new energy, plug-in hybrid is an indispensable key starting point, whether from the perspective of solving the pain points of users' actual car use, or from the height of the transformation and upgrading of the entire automotive industry chain. Professor Yao Chunde believes that the development of plug-in hybrid technology is the trend of the times, and it is also the only way for Chinese automobiles to lead the world. This also requires that domestic car companies like SAIC need to continue to make breakthroughs in technology.
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 higher-dimensional performance improvement in five key areas: engine, gearbox, battery, motor and energy control brain. For example, the thermal efficiency of the engine will break through to 46%, and take the lead in China to meet the "Euro VII" emission standard; 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 brain continues to be optimized, and the next-generation vehicle energy center concept is expected to be released in 2025.
In fact, this is also a move to start the SAIC brand. According to the official statement, the release of the DMH super hybrid technology brand marks that SAIC Roewe will start the quality and value war of its own brand "national team" in the homogeneous new energy market with a more confident brand image and stronger product competitiveness, and help China's new energy vehicle industry develop towards high quality and high level. In the future, relying on the DMH super hybrid technology brand, Roewe will also gather superior resources from all parties to accelerate the creation of the "first camp of plug-in hybrids" and provide global users with new hybrid options for Chinese brands.
Zu Bijie said at the conference: "Brand building is an important support for the further development of the mainland's intelligent networked new energy vehicle industry. At present, SAIC is benchmarking the construction of a world-class enterprise, making every effort to build a trillion-level automobile industry group with global competitiveness in the industry and international influence of the brand, and continuously building the SAIC brand by building SAIC with science and technology, quality SAIC, and responsibility SAIC. The launch of DMH super hybrid technology is the 'super integration' of science and technology SAIC, quality SAIC, and responsible SAIC, and it is also an important practice to launch the SAIC brand. ”
According to reports, in the face of a new round of global competition, SAIC Motor's own brand vehicle R&D platform for passenger cars - SAIC Innovation Research and Development Institute has been fully prepared in the fields of forward-looking technology, R&D personnel, hardware equipment, etc., to efficiently support the product development of the four major brands of Roewe, MG, Zhiji and Feifan and overseas markets. In addition, in terms of promoting product improvement through innovation, Zu Qijie said that SAIC will take the lead in mass production of vehicle products equipped with semi-solid-state batteries, and accelerate the research and development of all-solid-state battery vehicles, so as to fundamentally solve the shortcomings of power batteries in safety, battery life, low-temperature performance, fast charging and other aspects. At the same time, SAIC will also take the lead in launching the L3 high-level autonomous driving solution for mass production to solve users' worries about the safety, reliability, and product liability of autonomous driving.
