If the automotive field is compared to an exam, then hybrids must be the finale. In today's rapid development of new energy, all car companies are busy creating their own new energy vehicles. At present, pure electric vehicles have the problem of mileage anxiety due to their own technical problems and the limitations of objective factors such as charging pile coverage, and cannot completely replace fuel vehicles, and cars with hybrid systems are the current "version answer".
In the field of new energy vehicles, our independent brands are also beginning to emerge, have launched their own hybrid systems, its products equipped with hybrid systems have also achieved good sales results, today we will take a look at the hybrid systems of these independent brands what is the difference, some of the small partners who want to buy hybrid cars can also understand in advance, to see whose hybrid system is more suitable for you. The rise of independent brand hybrid field, BYD, Great Wall, Geely, who is the "shoulder handle"?
Due to the existence of Honda and Toyota in the field of hybrid systems, our own brands will have patent barriers when developing hybrid systems, which also leads to the fact that the hybrid systems of each brand are very different. The word BYD DM-i has appeared very frequently in the past two years, so what is this BYD DM-i? BYD DM-i is a hybrid technology independently developed by BYD, which is composed of a super hybrid system composed of a special engine for xiaoyun plug-in hybrid, EHS dual motors, DM-i super hybrid blade batteries, and a series of control systems.
And this hybrid system is also based on electricity, supplemented by oil. When the power is sufficient, the DM-i model is a pure electric vehicle, and when the power is insufficient, it will independently judge whether to use oil-electric hybrid or direct oil. The advantage of the DM-i hybrid system is that the car's internal combustion engine is always in the optimal output range, allowing for maximum thermal efficiency. In the case of low and medium speed, the generator is first used to generate electricity, and then the motor is driven by electricity, and the excess point power in this process will be charged into the battery to "squeeze the potential of each drop of oil", and then achieve the purpose of fuel saving.
The transmission efficiency in this mode is also higher than that of most gearboxes. BYD Automobile's BYD Tang, BYD Song PLUS and other models are equipped with this DM-i hybrid system, which is also very cost-effective in their respective fields, and also helps BYD Automobile rank first in the list of new energy vehicle sales in January 2022 with sales of 92,788 units.
After introducing the well-known DM-i, let's take a look at the recent "long face" of our country's Geely Ray God Qing Hi · X Hybrid Technology. It is said that this hybrid system is our own brand "Long Face" because the thermal efficiency of the engine it is equipped with has broken the world record, and its maximum thermal efficiency has reached 43.32%. Geely's hybrid system consists of a fuel engine, a P1 motor, a C0 clutch, a P2 motor (including a planetary gear set, a variable speed system) and a battery system. It is characterized by a three-speed shift + full-speed parallel.
Gilli Ray Divine Intelligence Hi · X hybrid system in the vehicle speed of 20km / h, the engine will be driven by the P1 motor, the engine will also be connected with the P2 motor through the C0 clutch, through the planetary gear group, the formation of power shunt effect, the fusion of the engine and the motor power to achieve power output, to achieve efficient fuel saving driving effect. This working principle sounds very much like the fusion of the "two fields" hybrid system, but the difference is that Honda's i-MMD hybrid system requires the engine to connect the motor through the clutch when the speed is very high, and the parallel power drive is realized.
And Gilli Ray's Mind God Force Hi · The X can be started at a speed of 20 km/h. Models equipped with this hybrid system, such as Hoshikoshi L, feel like "saving and energetic" when driving, and after actual measurement, the fuel consumption of Hoshikoshi L is within 4L, even lower than that of the same level of "Two Fields" models. Geely Automobile is also in the fifth place in the sales list mentioned earlier with this hybrid system.
Finally, let's talk about Great Wall Motors' lemon DHT hybrid system, which means that Great Wall Motors has finally reached the top of the hybrid technology pyramid. The Lemon DHT hybrid system consists of a high-efficiency hybrid engine, a highly integrated dual motor (drive motor, generator, generator can be used to drive) hybrid transmission, a high-efficiency hybrid battery, and a high-performance electric transaxle (equipped with a FOUR-wheel drive model with PHEV architecture).
This system is characterized by its overall smaller size, lighter weight and higher transmission performance. Two-wheel drive models can realize the engine, drive motor, generator three engine together drive, four-wheel drive model can even achieve engine, drive motor, generator, high-performance electric drive rear axle four engine joint drive. In addition, the lemon hybrid DHT system has three comprehensive powertrain combinations, covering a wide range, with three power architectures from 1.5L+ DHT100, 1.5T + DHT130 to 1.5T + DHT130 + P4, and the total power of the system is also from 140kW to 320kW, which can be selected according to the flexible combination of different levels of models.
Models equipped with the lemon hybrid system will obviously feel that the power is stronger than the "Two Fields" when driving, but the fuel consumption is slightly higher, and the fuel consumption per 100 kilometers is 4.6 liters. Of course, this slightly higher fuel consumption is for the "two fields", for the average car, the fuel consumption of 4.6L is also unimaginable. Great Wall Motors also ranked eighth in the january 2022 new energy vehicle sales list with this hybrid system.
The above is the hybrid system developed by our own brand car, each system has its own advantages, and the hybrid field is no longer the world of "two fields".
