Under the strong guidance and support of national policies, new energy vehicles have developed very rapidly in recent years. However, the problem of mileage anxiety and charging anxiety has always been accompanied by the development of new energy vehicles, even after some multinational luxury brands quickly intervene in the field of new energy, problems such as retention rate have followed.
Along with the problems of mileage, energy replenishment, and low carbon, automotive prophets have noticed that there is a growing call for a model to be able to drive pure electric and be driven by oil when it is inconvenient to charge, and that pure electric mileage can meet the daily commuting needs of low-carbon models.
PhEV models that have not been optimistic before, under the leadership of Weipai and other enterprises, have successfully created a long-lasting PHEV technical route, and ultra-long endurance and low-carbon environmental protection are increasingly optimistic about the industry and the market. Although long-endurance PHEV technology sounds complicated, under the leadership of consumption, long-endurance PHEV has indeed become the optimal solution in the field of current oil and electricity technology, and the inevitability and certainty of it are more worth thinking about.
| long endurance PHEV has become the optimal solution for vehicle power
According to the data of the Ministry of Public Security, as of now, the number of new energy vehicles in China has exceeded 9 million. Among them, the proportion of pure electric vehicles is more than 70%, and it is worth noting that the growth rate of plug-in hybrid models has been much higher than the growth rate of pure electric vehicles. In terms of subdivided sales, consumers are more inclined to long-range PHEV models in the plug-in hybrid model category.
Today, pure electric models are eager to make breakthroughs in energy density, ultra-high voltage fast charging, and power exchange technology, while fuel models are still wobbling in HEVs, PHEV, and range increases. New technologies and concepts that accompany new cars make consumers overwhelmed, and as the market scale expands, the problems of pure electric and fuel emerge one by one.
For pure electric models, strictly speaking, it is energy replenishment anxiety, no matter how far the mileage will face the problem of energy replenishment, whether it is ultra-high voltage fast charging or power replacement, it has not solved the efficiency problem. In other words, pure electric models are difficult to reach the convenience of refueling vehicles in any case. On the contrary, it is difficult for fuel models to achieve high intelligence, energy saving and low carbon.
Based on the fundamental consumption needs of this era, Weipai launched a long-lasting PHEV model, with the determination to solve the anxiety of new energy mileage and energy replenishment, and "kill" into the market.
On the basis of the mature DHT technology developed at this stage, innovation is carried out, and two direct drives are added, so that this set of technology can realize pure electric drive, extended range electric drive and direct engine drive, and achieve ultra-long endurance under the premise of ensuring reliability, which is a mature product guided by innovation.
Unlike the range extenders advocated by new power companies, the long-endurance PHEV will be expanded to adapt to the efficient operation of the engine after adding a two-speed direct drive system. In a range extender system, the wheels can only be driven by an electric motor, and the engine is only used to drive the generator to supply power, which allows the engine to maintain a constant economic speed at the same time, which also means that the motor has to cope with all working conditions alone. Therefore, in the general urban expressway and highway, the motor is running at full power, so it consumes more electricity, resulting in "energy-saving cars are not energy-saving".
The difference between Weipai's long-endurance PHEV technology is that the engine can also directly drive the vehicle, and the engine can be directly involved in the drive under the working conditions of lower motor efficiency and higher engine efficiency. This not only avoids the inefficient range of the motor, but also avoids the additional energy loss caused by the back and forth between kinetic energy, chemical energy and electrical energy, achieving higher efficiency.
Therefore, the long-endurance PHEV model of Mocha can achieve a low 5.55L WLC 100 km feed fuel consumption and WLTC 204km pure electric endurance, and the comprehensive endurance can achieve 1000+km. In fact, as one of the earliest enterprises in China to develop new energy technology, Weipai has invested more than 15 billion yuan in 5 years to support the progress in the field of technology, and for Weipai, long-endurance PHEV is just a "natural".
| innovation of "0 to 1" power for vehicles
In September 2020, China proposed a "double carbon" target, as the automotive industry accounts for 7.3% of total carbon dioxide emissions, it is facing decarbonization pressure. Under the dual carbon target, Chinese auto companies are required to come up with the most effective and pragmatic approach in the short term.
Therefore, the technical route of "power battery + fuel" reduces the dependence of automobiles on traditional fuels at the same time, reduces the high carbon emissions caused by the production of power batteries, divides the working conditions of the vehicle, and at the same time plays the long-board effect of low-speed domain electricity consumption and high-speed domain oil.
After Weipai took the lead in carrying long-endurance PHEV technology, other friends have joined the ranks of long-endurance PHEV, and it can be found that long-endurance PHEV is the next general trend of "electrification in a hybrid manner" of fuel vehicles.
In the interview, some experts said: "Long-endurance PHEV technology requires balanced electronic decision control between electricity, oil, oil and electricity, involving both the performance and quality of hardware, as well as the control logic, complexity and database that provides support." After solving individual problems, it is also necessary to solve the problem of system integration, as well as the integration of various subsystems and the interaction between different control systems. "Therefore, technical problems will block many companies out of the door, or can only be modified on the basis of fuel power, and Weipai can successfully land long-endurance PHEV technology, stemming from its deep engine, gearbox research and development experience and complete positive development of hybrid technology." Today, Weipai Long Endurance PHEV has gone from being a pioneer to a leader in this field.
No matter how the market changes, Weipai can gain insight into the most real needs of consumers. With the application of intelligent DHT, it marks that Weipai officially realizes the transformation of high-end new energy of the brand, and further consolidates the new positioning of "0 anxiety intelligent electric" with the most cutting-edge strength in the field of intelligent DHT technology, and shows the technical value and brand value of the brand.
As you can see, today's Wei Pai has changed too much. Starting from the Mocha DHT-PHEV, it officially opened the prelude to the comprehensive layout of the new category of "0 Anxiety Intelligent Electric" of Weipai, and in the future, all new products under Weipai will be equipped with two core technologies of intelligent DHT and NOH intelligent pilot auxiliary driving system, covering three series of urban SUVs, retros and MPV.
Whether it is the innovation of the underlying technology, or the upgrading of the configuration, or the exquisite design and workmanship, it reflects the efforts and ambitions of Weipai, or Chinese auto companies to move towards the highest point of the value chain. The high-end car market, which was previously dominated by joint venture brands, can now also occupy a place for Chinese brands.
The emergence of Weipai long-endurance PHEV technology has broken the restrictions of a number of pure electric and fuel vehicles, so that many pairs of contradictions such as electric and endurance, fuel and low carbon, intelligent and traditional cars, luxury and new cars are no longer contrary to each other.
| long-lasting PHEV provides more redundant space for intelligence
Consumer reports show that more than 87% of users buy SUV models in order to smoothly and comfortably navigate the city and flat roads, and take into account a certain degree of complex road conditions. The intelligent control system and intelligent pilot assistance system of Mocha PHEV can maximize the response to any unexpected situations that may occur during long-distance travel, eliminate driving hazards, thereby solving the worries of drivers and occupants, ensuring the safety, comfort and peace of mind of each mileage.
In the industry's view, this is the best embodiment of Mocha's long-endurance PHEV mature, accurate and pragmatic grasp of consumer needs and technology development trends. Behind it, is the comprehensive support of the current top hardware configuration, for example, Mocha is equipped with mobile EyeQ4 chip high computing power chip, while driving 5 millimeter wave radar, 12 ultrasonic radar, 4 surround view cameras, 1 perception camera and 1 high-definition map module to achieve NOH intelligent pilot assisted driving.
In this process, it should be noted that the premise of achieving a high degree of intelligence is that there is enough energy supply for all sensors and appliances. Therefore, the power system of traditional fuel vehicles has constraints at the level of power and voltage, and it is impossible to achieve a higher level of intelligence, while long-endurance PHEV technology can store more electricity while achieving fuel saving, which can be used by more electrical appliances, compared with the traditional phEV technology, long-endurance PHEV has a stronger intelligent redundancy range.
From the perspective of use scenarios, the NOH Intelligent Pilot Assisted Driving System covers six daily car scenes: entry and exit ramps, lane change, avoidance of sink entrance, distraction monitoring/fatigue monitoring, avoidance of large vehicles and identification of easy-to-mix fork intersections. At the same time, in the soft drive, Weipai relies on intelligent technologies such as AI, big data, and OTA, and gives full play to the advantages of artificial intelligence algorithms under the original AI FEED function of Coffee Smart Drive to achieve iterative updates that can grow.
People who are remembered by history are always making rules. Nowadays, looking at the entire Great Wall Motor and even Chinese automobiles, the responsibility assumed by Weipai is also evolving from the past "upward" to "forward". From a certain point of view, Weipai is not only at the forefront of Great Wall Motors' active transformation and change, but also in a leading position in the entire Transformation and Transformation of China's automobiles, under the empowerment of long-endurance PHEV technology, there is reason to believe that Weipai will lead Great Wall Motors, and even new power brands into a new era of innovation with vehicle power.
