It is a hybrid product for users all over the world, showing the world the vigorous power of China automobile brands in the new energy era.

Blending is an indispensable starting point for the transformation of automobile industry chain.

By the end of 2023, the production and sales of new energy vehicles in China ranked first in the world for nine consecutive years, and became the world’s largest automobile exporter for the first time. Under the wave of new energy, 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 automobile industry chain, blending is an indispensable key. Yao Chunde believes that the development of hybrid technology is the general trend.

On the one hand, there is a strong user demand to promote the hybrid technology in China. The market environment and users’ demand in China provide a natural "fertile ground" for car companies to develop hybrid technology. On the other hand, the breakthrough of China car companies in the plug-in technology is not to show off their skills, but based on real usage scenarios, which integrates the advantages of traditional fuel vehicles and electric vehicles and brings users real travel solutions. Taking the DMH super hybrid system as an example, Yao Chunde innovatively improved the off-axis P1 motor into a coaxial structure for the current mainstream P1+P3 hybrid configuration, which greatly improved the transmission efficiency, optimized the NVH performance, and made the whole system more efficient and the driving experience smoother and quieter. It can be seen that the plug-in technology is not a transitional technology, but a key technology to drive the traditional automobile to realize electric transformation and comprehensively improve the user’s travel experience, and it is also an indispensable technical support for China automobile to "grow from big to strong".

Roewe DMH: Super fusion is super hybrid.

"At the moment, hybrid technologies are blooming, products are emerging one after another, and user acceptance is getting higher and higher. It is predicted that by 2025, there will be a 1:1 situation between pure electricity and plug-in. The spring of plug-in and hybrid 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 technology center, said.

The greatest advantage of any technology with long-term value is that it can withstand precipitation and carry long-term optimization iteration. As early as 2010, SAIC proactively laid out the field of plug-in hybrid technology and regarded it as a technology worthy of long-term investment. In 2017, the first generation of EDU hybrid technology independently developed by SAIC won the second prize of the National Science and Technology Progress Award. Thanks to SAIC’s in-depth self-research on the core technology of powertrain, SAIC will also exceed 46% in the key index of engine thermal efficiency that affects the performance of hybrid system. After long-term technical accumulation and market verification, the DMH super hybrid technology released at this conference, with by going up one flight of stairs integration and intelligence, is a new kinetic energy for SAIC’s own brand to maintain its long-term competitiveness.

DMH super hybrid technology has three technical characteristics: modularization, integration and specialization. According to the modular design and serial configuration, the system matches different hybrid routes such as PHEV/EREV/HEV through a set of systems, which can cover the driving needs and fuel consumption regulations of different users around the world. At the same time, the system has many leading technologies such as "energy domain" global thermal management, powertrain brain PICU, engine +P1 motor coaxial structure, etc., with software algorithm as the core, matching special hardware such as hybrid high-efficiency engine, gearbox and long-life battery.

At present, DMH super hybrid technology has taken the lead in the Roewe D7 DMH and the Roewe D5X DMH, the new mainstream hybrid SUV with long battery life, and the product strength has been widely recognized. Not long ago, Roewe D7 DMH, on behalf of its own brand B-class car, challenged the extreme endurance of 2,000 km, and finally overcame the influence of bad weather, achieving a long endurance of 1962km and an average fuel consumption of 2.8L per 100 km, realizing the technical value transformation from technical strength to scene application, and showing the strength of China brand.

Qiu Jie, vice president of Innovation Research and Development Institute of SAIC and general manager of Jieneng Automobile Company, said that in the next three years, DMH super hybrid technology brands 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 it will take the lead in reaching the "Euro 7" emission standard in China; In terms of gearbox technology, the target carbon dioxide emission of the oil-electric hybrid route will not exceed 95g/km, and the plug-in hybrid and extended-range electric routes will adopt a new configuration of dual coaxial scheme; The energy control brain is continuously optimized, and the concept of the next generation vehicle energy center is expected to be released in 2025.

Start SAIC brand

With the joint efforts of the upstream and downstream of the industrial chain, automobiles have become a shining business card for China brands to go global. Among them, SAIC has won the "Double Champion" in domestic sales and vehicle export for eight consecutive years, and has become an excellent sample for actively practicing the "three transformations" in brand building.

Zu Sijie said at the conference: "Brand building is an important support for further developing China’s intelligent networked new energy automobile industry. At present, SAIC is building a world-class enterprise by benchmarking, making every effort to build itself into a trillion-dollar automobile industry group with global industrial competitiveness and brand international influence, and constantly making SAIC brand famous by building technology SAIC, quality SAIC and responsibility SAIC. The launch of DMH super hybrid technology is the’ super integration’ of technology SAIC, quality SAIC and responsibility SAIC, and it is also an important practice to start the SAIC brand. "
