The four working modes, with electricity as the main and oil as the auxiliary, have completely broken the bad feelings among extended-range vehicles, hybrid electric vehicles and plug-in hybrid electric vehicles, achieved the "trinity" effect, met the power technical characteristics of all hybrid electric vehicles in the automobile industry at present, and enabled the perfect balance between power and fuel economy to be achieved under any driving conditions.
What is the technical strength of hybrid power based on electricity?
Explore the current mainstream hybrid power technology, basically based on oil, supplemented by electricity. The original intention of hybrid is to optimize fuel economy and achieve better fuel efficiency. However, with the continuous development of technology and the increasing demand of users for automobiles, as well as the development strategy of peak carbon dioxide emission and carbon neutrality in the future, the market has higher and higher requirements for automobile performance and emissions. At present, including a variety of traditional hybrid technologies can improve the balance between power and fuel economy, but can not achieve the qualitative improvement of performance.
The birth of BYD DM-i super hybrid can perfectly solve the above problems. Since 2008, after three generations of DM technology changes, BYD launched DM-i technology at the beginning of this year, aiming at redefining hybrid vehicles and accelerating the process of transforming fuel vehicles into new energy vehicles. According to BYD's introduction, after three generations of DM technology upgrades, the fourth generation of DM technology is not named DM-4, but DM-i, because BYD believes that super hybrid has reached the ceiling level of hybrid technology, from hybrid logic, power performance and fuel economy. It has reached the most perfect balance. It is the best technical scheme for transitional fuel vehicles and pure electric vehicles at present.
Completely different from other hybrid technologies, super hybrid is mainly based on high-power motor+high-capacity power battery, supplemented by engine. In terms of power unit, BYD has specially built hybrid engine, EHS electric hybrid system and hybrid blade battery for DM-i technology, and tailored the most suitable power system for hybrid products. This brand-new power idea enables BYD DM-i super hybrid to achieve ultra-high efficiency and ultra-low fuel consumption without losing power performance.
With sufficient power, the DM-i super hybrid is a pure electric vehicle. When the power is insufficient, the DM-i Super Hybrid is a hybrid vehicle with ultra-low fuel consumption: driving in the urban area, 99% of the working conditions are driven by a motor, and the driving experience is infinitely close to that of a pure electric vehicle. At 865,438+0% of the working conditions, the engine is turned off and the fuel consumption is completely zero; High-speed driving, mainly parallel direct drive, the engine is driven in the high-efficiency interval, which simplifies the energy transfer link and realizes ultra-high efficiency and ultra-low fuel consumption.
Under NEDC and WLTC working conditions, the transmission ratio of DM-i super hybrid motor is as high as 88% and 82% respectively, which truly makes electricity the mainstay.
Mainly based on electricity, the ultra-low fuel consumption of DM-i super hybrid compact car is realized, and the fuel consumption of DM-i super hybrid compact car can be as low as 3.8L/ 100 km (NEDC working condition) under power loss; At the same time, it also brings a "more fuel-efficient and electricity-saving" experience. The pure electric cruising range of DM-i super hybrid vehicle can reach 120 km, and the comprehensive cruising range of oil and electricity exceeds 1200 km (NEDC working condition).
DM-i super hybrid vehicle also provides two charging modes: AC slow charging and DC fast charging. The charging convenience is the same as that of pure electric vehicle, which provides strong support for users to use pure electric mode more actively.
Good products are market-proven.
On June 5438+1October 1 1 this year, BYD officially launched the DM-i super hybrid technology, which was officially listed on Qin PLUS, Tang PLUS and Song Plus listed in March. Up to now, the order quantity of DM-i configuration version of three models has reached150,000, which is limited by production capacity. At present, BYD's DM-i models have * * *. In view of the shortage of supply, BYD has taken corresponding countermeasures to increase production and prepare DM-i models in all directions.
It is worth mentioning that the driving force reflected by the market has given BYD great confidence. As of May this year, BYD's new energy vehicles have completed the market sales of 6.5438+0 million vehicles, and it is confident to complete the second/kloc-0 million vehicles in the second half of next year. As far as the development form of new energy vehicles is concerned, super hybrid, as the ceiling of hybrid technology at present, is the best substitute for fuel vehicles at present because of its stronger performance integration ability. Compared with pure electricity, super hybrid still has its inherent advantages, which will qualitatively improve the practicality of the whole vehicle. Just as an ordinary hybrid upgrade technology, BYD is not so confident that it can greatly increase sales and even replace fuel vehicles. However, in contrast, although the hybrid electric vehicle is only a transitional product in stages, its inherent advantages over fuel vehicles and pure electric vehicles enable it to reach the peak of technological development in a short time and be more easily recognized by the market.
In recent years, major car companies around the world have successively laid out hybrid models. Judging from the global sales of new energy vehicles, hybrid vehicles can indeed bring good market share. Compared with the relatively easy blending of oil, BYD chose the most difficult blending technology route, and it turns out that the development prospect brought by this choice is limitless. From cost to supply chain, to product positioning and user response, BYD DM-i has proved its unique success. It is more in line with the current market development trend to build cars that users need and practical cars.
Conclusion: "Fast, provincial, quiet, smooth and green", five words summarize all the characteristics of BYD's DM-i super hybrid, and also comprehensively summarize BYD's current consumer product demand. After more than ten years of evolution, from the appearance of BYD's first F3DM model in 2008 to the release of the latest DM-i super hybrid this year, BYD's DM technology has accumulated a lot of experience and patents, and the cumulative sales volume of DM models has exceeded 420,000, accounting for 44% of the total sales volume of plug-in hybrid models in China market. With the continuous fermentation of the good reputation of DM-i models, it is bound to become the car choice of more consumers and truly realize the situation of competing with joint venture vehicles.
