In the age of electrification, is it still necessary to develop internal combustion engines? This question may have to be considered from both the technical and market levels. On a technical level, the internal combustion engine determines the efficiency and level of the entire hybrid system. Compared with the internal combustion engine, the structure of the electric drive assembly is simpler, and the efficiency is now 97% and 98%, and there is not much room for improvement, and the thermal efficiency of the internal combustion engine can now be more than 40%, and it may be increased to 47%, 48%, or even 50% in the future, and there is still room for improvement.
At the market level, independent brands want to go to sea, in overseas markets, subject to charging conditions, geographical conditions, consumption habits and policies and regulations, the speed of pure electric vehicles is very slow, fuel vehicles or hybrid vehicles, there will still be a large market, to develop overseas markets to become a world-class brand, that must be world-class in fuel power, to walk on multiple legs to be more reliable. Even in China, there may be 20%-30% of the market space reserved for fuel vehicles in the future, and as for hybrid models, whether plug-in hybrid or extended range, it is estimated that they will account for more than 40% in the future. Therefore, the high-efficiency internal combustion engine is still the key winner or loser.
Following the release of the new Blue Whale power platform by Changan on March 13, on October 18, the release of the smart new Blue Whale global power solution and the advanced listing conference of Changan Qiyuan A07/A05/Q05 were held in Changan Digital Intelligence Factory on October 18. At the same time, Changan Qiyuan's three products, Qiyuan A07, Qiyuan A05 and Qiyuan Q05, which are equipped with smart new Blue Whale 3.0 technology, have also been released.
In terms of hardware, as an advanced engine and hybrid electric drive platform, the core technology of the new Blue Whale 3.0 adopts the world's first and only industry-only 500bar high-pressure fuel injection system, the world's first 150mJ high-energy ignition system, the world's first electronic oil pump, and the industry's highest compression ratio design, making the thermal efficiency of hybrid engine mass production reach 44.39%. In the reserve scheme, the three-spark plug ignition and compound pressurization technology are applied to achieve ultra-thin and ultra-clean combustion with an air-fuel ratio of more than 2.0, and the reserve thermal efficiency has reached the highest level in the industry of 47.03%. In addition, in terms of high-efficiency hybrid electric drive, the oil-electric conversion coefficient is as high as 3.63kWh/L, and the maximum efficiency of the drive motor reaches 98.1%, both of which are at the industry-leading level. It is worth mentioning that Changan is the only hybrid system in the industry that adopts 10-layer flat wire motor technology.
Secondly, in terms of software, the original IEM3.0 intelligent power control system, the advanced energy consumption algorithm further helps to save energy and efficiency, and the dual advancement of driving algorithm and intelligent algorithm not only allows users to travel more securely, but also enjoy the journey.
According to the plan, the new Blue Whale iEM3.0 high-level intelligent control, covering a series of algorithms such as advanced energy consumption algorithms, advanced driving algorithms, and advanced intelligent algorithms, will be upgraded to new and old users of many Changan models OTA in stages. The Changan UNI-Z iDD, which has already been launched, will usher in an OTA upgrade within the year.
Advanced energy consumption algorithm: The original IEM3.0 intelligent power control system adds intelligent scene recognition on the basis of 2.0, optimizes the distribution of energy in real time through the global planning of the algorithm, and ensures that the engine and motor run in the high-efficiency area, compared with the plug-in hybrid car of the same level, the fuel consumption is reduced by 10%, and the fuel consumption is 100km more than 100km on a tank of oil. Scene recognition and self-adaptation, through the core algorithms such as all-terrain driving self-adaptation, battery SOC self-adaptation, geographical environment thermal efficiency adaptation, and navigation-based self-adaptation of oil and electricity distribution, the vehicle can dynamically adjust the system in a wide temperature range of minus 40 °C to 55 °C and an altitude of 0 to 4700 meters to achieve optimal energy consumption. The AI energy prediction management function improves the accuracy of energy planning by developing three high-level algorithms: destination prediction, charging habit prediction, and driving style recognition, and further reduces fuel consumption by 5% through actual measurement.
Advanced driving algorithm: Changan's self-developed longitudinal intent matching model and acceleration closed-loop control algorithm realize the linear matching of actual acceleration and expected acceleration to ensure accurate control of the user's longitudinal body feeling. Let novices become old drivers in seconds. The AI health management technology of the power system provides 24-hour all-weather protection. Once an abnormality is found, the system will immediately send an alert to the user and provide personalized health management advice.
Advanced intelligent algorithms: First, the driving mode adaptive technology includes three core algorithms: real-time scene recognition, driving style clustering, and automatic driving mode matching. Secondly, it pioneered the industry's first power data customization service technology, which not only supports in-app upgrades and sharing, but also introduces interactive functions such as driving PK. By using the advanced large language model feature extraction algorithm, combined with the knowledge graph and vector database, the recommendation of personalized driving package is realized.
The smart new Blue Whale 3.0 makes the cost of new energy vehicles more economical. Taking Qiyuan A05 as an example, after actual testing, the model equipped with the smart new Blue Whale 3.0 uses home charging piles for short-distance commuting, assuming that the trough electricity price is 0.34 yuan/kWh, and it costs less than 5 cents per kilometer; Weekend travel with 200 kilometers of comprehensive road conditions measurement, even if the use of public charging piles, the effect of saving money is also excellent, the comprehensive use cost is only two cents, if short-distance travel is also charged with home piles, the cost of using the car will be lower. The smart new Blue Whale 3.0 realizes "the cost of using the whole domain and all scenarios is reduced to 0.22 yuan", so that the monthly car cost of small families is only more than 80, and more than 500 can be saved every month.
For ordinary office workers, "driving is so tired, sitting in the car is still dizzy, daily maintenance is time-consuming and troublesome" and other slots, driving in the magic 8D city, the mountain road ups and downs, the accelerator and brake are constantly switched and stepped on, and the user is prone to fatigue. The new Blue Whale 3.0 power software will automatically and dynamically compensate the driving torque and energy recovery intensity according to the terrain feedback, so that the amount of accelerator and brake pedal operation is reduced by 60%, making driving easier.
Because the acceleration and deceleration characteristics of new energy vehicles are different from those of traditional fuel vehicles, the difference between the real acceleration and the user's expected acceleration is large, which can easily cause motion sickness when acting on the pituitary gland. Relevant studies have shown that the upper limit of the threshold of the acceleration change rate that the human body can adapt to is 5.5m/s³, and the smart new Blue Whale 3.0 controls the user's motion sickness index to 4.15/s³ through software algorithms, which is significantly lower than the 6.25m/s³ of competitors. In order to provide users with convenient, real-time, and unexpected car maintenance services, the smart new Blue Whale 3.0 has developed smart functions such as smart maintenance, power health monitoring, and residual value evaluation.
The ultimate goal of the car is to evolve into a work helper, a life assistant, a money-earning expert, and an emotionally intelligent companion. The smart new Blue Whale 3.0 has 1000+ driving modes, 100+ personalized gameplay, and 1 exclusive driving package, which can meet the needs of users in different car environments, realize one car with multiple senses, one car with multiple uses and better driving safety, through the integration of four key system domains of power, chassis, cockpit, and cloud platform, more than 100 gameplay combinations in more than 20 scenarios have been realized, increasing the playability of the power system, and giving new social attributes. For example, you can package and share your driving data with your good friends to experience; You can also download the driving package released by the official and city experts to experience how they drive and make driving fun; You can also create driving data and become a creator. Generate user-specific driving packages based on data such as users' historical driving behaviors, car usage scenarios, and travel preferences, and update iteratively every 500km.
