In July 2020, BYD released a DM-P platform. Based on the existing DM3.0 platform DM-P platform, the technical architecture of the engine + BSG start-up motor + front drive motor + in the back drive motor +, continues to adhere to the design of performance idea. The flagship model of the DM3.0 platform has been released to the 2018, 2020 and 2021 three modifications. 2018 Tang DM configured BSG motor, front drive motor and rear drive motor electronically controlled system alone; 2020 Tang DM’s BSG motor and pre-drive motor electronically controlled “2 in 1” integration; 2021 Tang DM is equipped with the 200 kW electric drive assembly of the SiC electrical control system at the same time that the “2-in 1” electric drive control system is retained.
Followed, BYD released a new DM-I platform in January 2021, and 3 new models including Qin Plus. Based on the DM-I platform with energy-saving, it constitutes the latest models of BYD in 2021 with the DM-P platform with performance.
Declaration: The “DM-X Platform” mentioned in this article only combines the new energy intelligence analysis network to bond Tydi’s last 2 years of trivial information, stitching forecast. Finally, the information released by BYD is accurate.
Under the DM-P platform:
Continued DM3.0 DM-P platform, equipped with an old-state 2.0Ti engine, DCT-based preamp Electric drive system, three-dimensional lithium battery system, and conventional thermal management control system. As a DM3.0 platform or or is the flagship model of the DM-P platform, the three engine four-wheel DD DM series has launched 2018, 2020 and 2021 and in the period to launch a two-engine four-wheel DD DM and Double Engine Driven DM.
On the latest 2021 Tang DM, the old-state 2.0Ti engine plug-in 15000 rpm, water-cooled BSG start-stop motor, but the highest driving power efficiency increase To 12 kW (2018Tang DM’s driving power is 10-11 kilowatts; front drive motor and BSG start-stop motor control system have been integrated with “2 in 1”; the rear drive motor is upgraded to the SiC Electronic Control of the Han DM adaptation 200 kW Version (currently BYD manufacturing technology with the highest technology content). 
Need to note is that 2021 Tang DM front drive bridge output power is 241 kW (141 kW + 110 kW), the post-drive bridge output power is 200 kW, and it is suitable The sixth technical state of the six technical state of the super electricity system is still in the “front-heavy light” torque allocation state, and the 2018 Tang DM has evolved in the driving power efficiency and the bridge torque re-allocation strategy.
Under the DM-I platform: 
Obstera-blended dedicated engine is not only equipped with Atkinson circulating technology to increase thermal efficiency (to 43.04%), which is also based on variable The electron pump of the flow is integrated with the engine body to obtain a layered heat dissipation servo between the cylinder head and the cylinder, ultimately integrated with the vehicle thermal management system.
EHS-in-depth electrical drive system, because introduced the flat line “card” winding technology, the integrated generator and drive motor increase the torque density while the length is large Shorten, ultimately become a high integration of dual motors + dual electrocomposites. The EHS insert special electric drive system has a modification of 132 kW, 145 kWh 1000 kW power level drive motor.
The power generation power of these three EHS systems is never mentioned in the official. Depending on the EHS plug-of-specific electrical drive system structure comparison, the length of different drive motors and their adapted generators will be completely consistent, and the power distinguishing between the magnetic steel and the flat line winding ratio. In other words, the EHS plug-in special electric drive system will be unified to configure the maximum power generation efficiency of 90-100 kW generators, or according to the adaptation of different displacements 骁 云 专 专 专 专 专 发 发 发 发 发 发machine. 
Super mixed special power type blade battery is presuppose safety, remove the PTC control module, water-cooled board control module and not less than1 set of electric water pumps and many “X pass” valve body constitute a thermal management control system. Relying on a special power type blade battery from pulse preheating function, high temperature heat dissipation capacity of the refrigerant from the electric air conditioner compressor directly outputs the cost, efficiency and safety.
YES! The BYD DM-I platform is a technical solution for the three levels of engine, electric drive and power batteries, while taking huge improvements. Although 2021 Tang DM is more efficient in the pre-electron control system than 2018 Tang DM, it has improved the “quality” leap. Instead, the new DM-I platform has introduced 系 插 专 专 专 专 专 专 专 插 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统 系统Quality of the quality.
Prerequisitated for energy saving, DM-I platform mass production Qin Plus, Song Plus and Tang PLUS are two-wheel drive models; 
Prerequisites, based on DM-P platform Produced Tang DM, Song Pro DM and Han DM are all four-wheel drive;
On the basis of the DM-I platform, the four-wheel drive model is launched?
If you continue with energy saving, the generator power in the EHS plug-in special electric drive system is 90-100 kilowatts, or can meet the front 132 kW 16000 rev / power drive system, and 1 set 120 kW, 15500-16000 rpm, “3-in-1” electric drive system, the balance of driving and discharge efficiency.
However, this front and rear electric drive system has a tempority of the bridge torque caused by the technical generation of 1-2 years to continue “pre-heavy light”, and DM-P platform Tang DM (three engine four drive The version did not pull the “quality” change.
Instead, at 2021 Tang DM Dual Engine Four-Tropical and Han DM, by removing the front drive motor, reloading the SiC Electronic control, 15500 rpm, 200 kW level “3 1 “Electrical drive assembly, in cost, performance, and driving charge and discharge efficiency are almost” successful “.
Obviously, develop four-wheel drive version on the basis of the DM-I platform, that is, the cost is not pulledThe technical gap between the DM-P platform is opened.
Who new DM-X platform?
Integrated many messages and judgments, the Snapdragon series high-power + high-popular inline 4-cylinder 2.0T engine has completed testing, and more powerful power variable flow electronic water pump for layered heat dissipation technology , Is verified on the 云 插 专用 1.5 engine is obtained.
Once the 云 插 专用 2.0T engine passes to a flat wire generator +160 kW flat wire by replacing power generation power The high-power EHS electric drive system composed of the drive motor means even in the increase of the maximum output power of 1 group, 16000 rpm, oil cooling heat, SiC electronically controlled “3 in 1” electric drive assembly, can do Equilibrium is even better to the power generation and discharge efficiency.
Electricized new super electric four-drive technology?
The DM-X platform should be based on the DM-I platform, using a more powerful high efficiency 2.0T engine, strengthen the power generation EHS electric drive system, retain the special power type blade battery system, increase 1 At least 200 kWrade rear electric drive system platform.
It is very likely that the first model under the DM-X platform, the front drive bridge output power is at 160 kW (180 kW), and the post-drive bridge output power is 200 kW (or 220 kW), 云 系 插 专用 2.0T engine only uses direct drives or direct drives and power generation, more working conditions only for power generation drives, and power generation, electricity storage (To the power battery).
Interestingly, the super electrical four-wheel drive technology of the DM3.0 platform is based on mechanized DCT drive system; the new super electric four-wheel drive technology from the DM-X platform It is based on an electric EHS electrical transmission system. This triggered a new super electricity four-wheel drive technology and control strategy that coexisteed with the DM-X platform.
The author has the words:
Previously in new energy intelligence analysisThe network has been proposed that different manufacturers have primarily determined the development direction of new energy technology according to their own “longboard”, and try to avoid their own “short board”.
Take the new Touar EHYBRID as an example, which is based on the traditional power and Torson four-wheel drive system, which is the most good, and add 1 between the engine and vertical 8AT. Taiwan 100 kW drive motor). Although the performance of this limited electricity is small, the risk is small and the cost is less.
As an example, the BYD light PLUS is based on the power and power battery system of the self-employed power and power battery system (插 专用), EHS plug-for special electric drive system, Special power type blade battery. Although this substantially electricity has enhanced enhancement, it is more than the Reliability of EV and DM model launched by BYD in DM1.0, DM2.0, DM3.0 and E platforms, E + platform, E ++ platforms. The same level of models.
There is a technical generation of “Quality” between the DM-P platform and the DM-I platform is caused by BYD. The DM-I platform has returned to DM-X and returned to BYD’s “iterative” development strategy. Regardless of the DM-I platform or the DM-X platform, it can achieve efficiency, performance, and powerful balance setting. It is BYD in the engine, electric drive system full electricity, and continuously maintains the absolute leading hard strength of the power battery.
The reason why BYD can easily develop high-efficiency DM-I platforms, high-performance DM-X platforms, and extended electricity new super electric four-drive technology, one of them is important Factors are based on flat-line “card issuance” winding generators and drive motors independently developed, self-contained, and full-time applications.
