Why is Hongqi the first to realize the advancement of hybrid technology?

The domestic new energy vehicle market is growing in an all-round way, not only reflected in the rapid growth of market size, but also in terms of technical routes, which are already competing with each other.

Sales data released by the China Automobile Association shows that the annual sales volume of China's new energy market in 2022 will be close to 7 million vehicles, accounting for 25.6% of the overall sales. The "New Energy Vehicle Industry Development Plan (2021-2035)" has been completed ahead of schedule. The 2025 development goals proposed by "Year)".

If the current new energy vehicle market is divided according to technical routes, it also shows a situation of multiple developments, especially the pure electric and plug-in hybrid markets, which have benefited from long-term policies. Encouragement and the level of investment of various manufacturers, the two major market segments are exploding in full swing.

The pure electric market is still the main body of the current new energy vehicle market. In 2022, domestic pure electric vehicle sales will be 5.365 million units, a year-on-year increase of 81.6%. In addition to pure electricity, the domestic plug-in hybrid market is also accelerating across the board. In fact, from the perspective of growth rate, compared with the pure electric market that we have paid more attention to before, the plug-in hybrid market has exploded even more violently. In 2022, the domestic plug-in hybrid market will grow at a year-on-year growth rate of 160.5% , handed over a sales report of over 1.5 million vehicles.

Obviously, plug-in hybrid is already a technical route that is developed in parallel with the pure electric route and promoted by integration. It is foreseeable that plug-in hybrids will be an indispensable force on the new energy track for a long time to come, and its technological evolution and development will also become the key to promoting the continued growth of China's new energy industry.

Then the question arises, what is the general direction of technology upgrade in the domestic plug-in hybrid market? At the new energy technology conference not long ago, the Hongqi brand gave the answer.

Hongqi’s technical heritage

At the Hongqi New Energy Technology Conference on April 8, Qiu Xiandong, director, general manager and deputy secretary of the Party Committee of China FAW, announced that under the "Flag" super structure The third largest platform - Hongqi hybrid platform HMP (HQ Modular Power) officially debuts.

We need to first talk about what the "Flag" super architecture is, which is related to the latest leap forward of the Hongqi brand.

On January 8, 2018, the new Hongqi brand strategy was officially released. In the following five years, Hongqi achieved a great leap in brand value and market performance. In 2021 and 2022, the annual sales of the Hongqi brand have stabilized at more than 300,000 vehicles. Compared with five years ago, sales have soared 65 times, creating a big miracle in the Chinese automobile market.

On the same day five years later - January 8, 2023, the Hongqi brand once again released a new brand strategy, starting a new journey of its second leap. This time, Hongqi shouted out the new brand slogan of "All in" new energy, and the foundation to support the Hongqi brand to complete its transition in the new energy field is the "Flag" super architecture.

As early as 2018, when China's new energy vehicle market was in the ascendant, the Hongqi brand took the lead in launching the research and development of key new energy technologies, which lasted five years. , and finally brought together all the major breakthroughs and all the latest results of China FAW's 8 major technology field groups and 115 key technology fields to create a high-end electric intelligent super architecture FMEs (referred to as the "Flag" super architecture). At present, the "Flag" super architecture already has an electric platform HME and an intelligent platform HIS. Together with the newly released third platform-hybrid platform HMP, the Hongqi brand has established a platform that can meet the needs of R&D, manufacturing and production of various types of new energy vehicles. A complete system to meet the needs of different users.

Obviously, on the two future-oriented new energy technology routes of pure electric and plug-in hybrid, Hongqi has officially embarked on a new journey of subversion relying on its accumulated experience in core technologies.

“The platform takes into account both horizontal and vertical configurations, and is composed of four core systems of hybrid transmission, hybrid engine, intelligent electric drive and safety battery, as well as an intelligent energy control model, comprehensively constructing the Hongqi The technological leadership of plug-in hybrid vehicles!" Qiu Xiandong summarized the main highlights of the HMP hybrid platform at the press conference. The HMP platform took five years of research and development and broke through 526 key core technologies, which will bring another technological revolution in China's plug-in hybrid market.

Hongqi’s hybrid technology

If you use one word to describe the HMP platform, technological advancement should be the most appropriate.

In the past five years, during the process of Hongqi's intensive research and development, China's plug-in hybrid market has gradually completed the process from germination to gradual growth. What kind of hybrid vehicles do end users need? Where are consumers’ real pain points? The market has already given initial feedback on these core issues. What Hongqi is doing is actually relying on the technological innovation advantages of China FAW to transform it into the best solution to solve the core pain points of users. This solution is finally implemented at the execution level and is the HMP hybrid platform.

The Hongqi HMP hybrid platform has four core systems, and they respectively correspond to the technical difficulties that urgently need to be solved in the current domestic plug-in hybrid market.

For a long time, many users who have purchased plug-in hybrid models have a common problem, which is high speed noise and unbearable fuel consumption. The high-efficiency hybrid transmission system of the Hongqi HMP hybrid platform solves this problem.

Hongqi's world's first longitudinally mounted front-drive dual-motor multi-speed hybrid transmission - LDU45, realizes the integrated integration of drive axle, transmission, motor and controller, solving the problem of forward transmission of traditional longitudinally mounted transmission It solves the technical difficulties of power and achieves the shortest transmission path and the lowest system loss. The multi-speed design can keep the engine speed below 2,000 rpm during high-speed cruising, always in the high-efficiency and low-noise range, and perfectly solves the problems of high-speed noise and high fuel consumption of most current hybrid models.

In addition, Hongqi has also developed a more compact and more efficient transverse hybrid transmission - HDU35. Through the application of new materials and new processes, it can The system operation power consumption is reduced by 80% compared with similar products. In the future, the HDU35 transmission will be mainly used to develop A and B-class hybrid models, and the LDU45 transmission will be mainly used to develop C-class and above hybrid models.

The engine in the hybrid system cannot take into account both environmental protection and performance, which is also a fundamental problem in the industry. Previously, many plug-in hybrid users In the process of daily driving, the fundamental crux of completely equating the use of vehicles with gasoline vehicles is here. Performance and environmental protection can only have their cake and eat it too, right? Hongqi’s answer is: “NO”. The key lies in the choice between cost and meeting the actual needs of customers. The Hongqi HMP hybrid platform brings two hybrid engines, 20TD and 15TD. The thermal efficiency is the highest in the industry, reaching 44.3 and 45.2 respectively. On this basis, "cleaner" and "more powerful" have achieved true compatible. It is also worth mentioning that, facing the future, Hongqi has also reserved the next generation of lean-burn engines, with the measured thermal efficiency exceeding 47. Next, Hongqi will also be a flag that will continue to lead the new technological innovation direction of hybrid engines.

Let’s look at the next long-term common demand of plug-in hybrid users - power and control. Driving as you wish is a beautiful vision that is often mentioned when talking about car handling performance. However, there have been very few plug-in hybrid products on the market that truly achieve this. Hongqi’s power decoupled electric drive system will provide a model for solving problems for the entire industry. Under the influence of the innovative structure of intelligent disconnection of electric auxiliary drive, Hongqi's first power decoupled electric drive system can automatically switch between four-wheel drive and two-wheel drive modes within 100ms, maintaining the best power performance while allowing the four-wheel drive to achieve The energy consumption level is the same as that of two-wheel drive vehicles, setting a new benchmark in the electric drive industry.

Finally, of course, the core element of new energy vehicles is the battery.

When it comes to batteries, users are most concerned about two things: safety and low-temperature battery life. Hongqi’s highly safe and low-temperature-resistant battery system realizes all-scenario safety and all-climate security for power batteries. On the premise of multiple safety protections, it also Brings significant improvement in low temperature performance. Let’s talk about some key data. Hongqi’s lightweight all-composite box has a strength of up to 1000MPa and can withstand high temperatures of 1000°C. In order to solve the problem of battery performance degradation in electric vehicles in low-temperature environments, Hongqi has also developed low-temperature active batteries and targeted multi-source intelligent heating technology, truly allowing users to travel freely without fear of low temperatures.

Another important point is that based on the four core systems, Hongqi has also developed an exclusive smart energy control model. What exactly does this model do? Simply put, it is the control officer of the entire system, fully unleashing the potential of the system while achieving precise control. With this set of smart energy control models, Hongqi will truly become an "ace player" both internally and externally. It can self-identify and adapt internally to achieve the best results with minimal energy consumption; it can also control the external environment according to the cloud Big data and navigation and other road network information can be accurately predicted and optimal adjustments made in advance, so that the entire system is in the best condition at all times.

It can be said that, relying on original advanced technology and highly innovative configuration solutions, the Hongqi HMP hybrid platform truly covers the full range of user car scenarios, allowing plug-in Hybrid has truly become an advanced technology that can advance in parallel with pure electric lines.

Conclusion: From both the policy environment and the actual market demand, the development of hybrid technology can be regarded as an important fulcrum for fully embracing electrification in the future. The market performance in 2022 has also been verified. Plug-in hybrid can perfectly transform the basic market predictions of traditional petrol vehicle customers.

Facing the future, who can truly solve the actual car-using pain points of end users? Who can truly achieve the perfect unity of power and economy? In the final analysis, it depends on whether there is real technology accumulation and technological leadership. From this perspective, the Hongqi brand already has the technical conditions to take the lead, and the hybrid explosive period of the Hongqi brand is about to come.
