Starting from Sandian technology, it has the strength to build leading performance.
Engine, motor drive, motor control, battery charging and discharging, power output stability, fuel saving effect, NVH performance. For traditional fuel automobile enterprises, the complexity of plug-in hybrid technology is a major difficulty in research and development. Due to the lack of independent research and development of batteries, traditional fuel automobile enterprises have obvious shortcomings in the research and development of batteries and motor control, and can only rely on partners. However, partners often develop "moderate" products that meet the needs of most customers based on many factors such as market and cost, which is also the reason why the performance of many plug-in hybrid vehicles, including joint venture brands, is generally weak.
As the pioneer and leader of plug-in hybrid vehicles, BYD has been committed to the research and development of plug-in hybrid technology for 12 years, and has a complete new energy industry chain envied by the industry, and has developed its own three-electric system. It is one of the earliest manufacturers in the world to develop plug-in hybrid electric vehicles by using the three-electricity technology. The powerful advantages of new energy technology give BYD the strength and confidence to develop electrical systems according to performance design goals and build plug-in hybrid vehicles with leading performance.
DM-p focuses on "absolute performance" and sets a benchmark for the performance of new energy vehicles.
In fact, in the development of data mining technology in BYD in recent ten years, great attention has been paid to the dynamic performance of large-displacement fuel vehicles. Since the second generation DM technology started the "542" era (100 km acceleration within 5 seconds, full-time electric four-wheel drive, 100 km fuel consumption less than 2L), performance has become an important label of BYD DM technology.
In 2020, BYD introduced DM-p technology with "absolute performance" as the main focus. Compared with the previous three generations of technology, it has further strengthened the "integration of oil and electricity" and achieved super power. Both Han DM and 202 1 Tang DM with DM-p technology have absolute performance of 4 seconds zero acceleration, and their dynamic performance crushes large-displacement fuel vehicles, becoming performance benchmarks of the same class.
Taking DM in South Korea as an example, the "dual-engine four-wheel drive" power architecture with a 2.0T front motor and a rear motor is completely different from the motor power architecture adopted by many foreign brands of plug-in hybrid vehicles. The motor of the latter is placed at the front end of the gearbox, which limits the power output of the motor; However, the Korean DM adopts the power layout of front and rear separation, and the driving motor is arranged on the rear axle, which can give full play to the motor performance and achieve higher power output. In terms of performance parameters, the maximum power of Korean DM system is 32 1kW and the maximum torque is 650N? M, zero acceleration only takes 4.7s Compared with PHEV, HEV and fuel vehicles of the same grade, there is no suspense in winning super power performance, even in the face of a million fuel luxury cars.
One of the difficulties of plug-in hybrid technology lies in the power connection between engine and motor, and how to provide consistent strong power experience under the condition of sufficient and insufficient power. Many plug-in hybrid electric vehicles have different power performance under the condition of insufficient power and power. BYD DM-P model can give consideration to both strong power and durability. The core is that the ——25kW high-power and high-voltage BSG motor is enough for daily driving, and the 360V high-voltage design fully ensures the charging efficiency, so that the system power is always sufficient and the power output is strong for a long time.
DM-i focuses on "ultra-low fuel consumption" to accelerate the market share of fuel vehicles.
Korean DM and 202 1 Tang DM using DM-p technology became "explosions" as soon as they went on the market. Korea, BYD and Tang New Energy's double flagships 10 * * sold 1 1266 vehicles, ranking first in the sales of high-end new energy China brand cars. However, BYD is not satisfied with this. After the mature application of DM-p technology, it took the lead in "strategic subdivision" of plug-in hybrid technology in the industry, and recently launched "ultra-low fuel consumption" DM-i super hybrid technology.
In the eyes of many people in the industry, BYD's DM-P technology focuses on the high-end new energy vehicle market, and DM-i technology will further accelerate the pace of new energy vehicles replacing traditional fuel vehicles. From the release details, DM-i technology adopts BYD's latest plug-in hybrid architecture and energy management system, which completely surpasses fuel vehicles in economy, power and comfort. As one of the core components, Xiaoyun Hybrid 1.5L high-efficiency engine has reached a new high of 43.04% for mass-produced gasoline engines worldwide, laying a solid foundation for ultra-low fuel consumption.
Qin PLUS is the first car equipped with DM-i super hybrid technology, which was released for the first time at the auto show and brought surprises to the audience. Compared with cars of the same class, Qin PLUS's revolutionary fuel consumption is as low as 3.8L/ 100km, and its competitive advantages such as abundant power, super smoothness and super silence not only re-establish the standard of A-class family cars, but also enable brand cars to "recover lost ground" in the case of the largest market share and the fiercest competition in fuel vehicles.
With the dual platform strategy of DM-p and DM-i, BYD has further consolidated its leading position in the field of plug-in hybrid power. It is reasonable to believe that BYD, adhering to the development concept of "technology is king and innovation is the foundation", will continue to make breakthroughs and innovations in the field of new energy technologies and lead the industry to move forward.
