In the past 2021, new energy vehicles have exploded. Ask an extreme question: Is the internal combustion opportunity withdrawing from the stage of history? I don't think so, but in what ways to help consumers solve their travel needs? The best way is necessarily a hybrid system, which will not only not make consumers have range anxiety, but also bring consumers a smoother, fuel-efficient driving experience.
Speaking of hybrid systems, of course, in addition to Toyota Honda, the two veterans of the hybrid level, domestic independent brands are also actively developing their own hybrid systems, and the intensive launch of hybrid products will make the sales of independent car companies "go to a higher level". This article is intended to help users initially understand the research and development achievements of BYD, Changan, Great Wall, Chery, Geely, and other mainstream independent brands in the field of hybridization, hoping to bring some help to users.
The following is the text:
BYD DM-i system
Let's take a look at BYD first, everyone knows that BYD's DM-i hybrid system is because the current BYD car series has been almost all replaced with DM-i models, and the market performance is quite impressive. The key components of this system are: dedicated high-efficiency engine + EHS mixing system + control system + blade battery, and the vehicle drive mode is mainly electric.
The working mode of dm-i system has the following four types: 1. EV pure electric drive mode: when starting or at low and medium speed, the engine does not start, and the pure electric driving of the vehicle is driven by the drive motor alone, giving full play to the advantages of large torque, high efficiency and low noise of the drive motor; HEV series mode: When driving at medium and high speed, the engine works in the optimal economic zone, drives the generator to generate electricity, and the electric energy drives the drive motor to maintain the balance of electricity. When the generator is not powered enough, the battery replenishes the power to the driving motor, and when the generator has sufficient power supply, the additional power is charged to the battery. 3. HEV parallel mode: when driving at high speed or high power output, the engine and the motor drive the vehicle together. 4. Engine drive mode: When cruising at high speed, the clutch is combined and the engine works in the optimal economic zone. These four working modes, in fact, have covered all the scenes of users using the vehicle, based on this hybrid system, the official said that only 3.8L of fuel consumption is required for 100 kilometers. If everything is ready, the comprehensive cruising range of co-oil and electricity is reported to exceed 1200 kilometers. Many media have measured that fuel consumption will be lower.
Changan Blue Whale i-DD Hybrid System
Changan's Blue Whale i-DD hybrid system was also released at last year's Chongqing Auto Show, relative to these car companies later Than Changan launched the iDD hybrid system, known as a global hybrid solution, including high-performance Blue Whale engine + high-efficiency Blue Whale electric drive transmission + super capacity PHEV battery + intelligent control system, will cover a variety of hybrid technology solutions including 48V light hybrid, HEV, PHEV and REEV (extended range hybrid), It can also be applied to all models from A class to C in a platform application.
The iDD hybrid system integrates the HEV intelligent drive system, which adopts motor drive at low speed and engine intervention at medium and high speed, which saves 40% of fuel compared with the traditional fuel vehicle of the same level; it can also intelligently adjust the kinetic energy recovery system according to real-time road condition feedback to supplement the electric drive system with more power. Under the comprehensive road conditions, the blue whale iDD hybrid technology can reach up to 1100 kilometers.
Great Wall Lemon Hybrid DHT
In hybrid technology, the fastest action is Great Wall Motors. As early as 2018, Great Wall began to develop hybrid technology, and at the end of 2020, it officially released lemon hybrid DHT technology. Lemon hybrid DHT adopts a dual-motor hybrid topology, with pure electricity, mixed connection, series, energy recovery and other working modes, intelligent switching through the control system. The power architecture is divided into HEV (Oil-Electric Hybrid) and PHEV (Plug-in Hybrid).
Compared with the competitors, the special point of the lemon hybrid DHT is that it adopts a highly integrated internal combustion engine + transmission + dual motor + controller device, and when the engine is directly driven, the first two gears of the engine are directly driven, achieving the highest efficiency and the strongest power in the full speed range, while the competitors generally have only one gear.
Chery Kunpeng Power DHT
Chery's Kunpeng Power DHT in the era of hybrid is not behind, not long ago the Xingtu brand released the "Star Core Power ET-i full engine supermix", which can be seen as the "Starway Version" of Chery Hybrid Technology, using the hybrid gearbox DHT, with the technical advantages of 3 engines, 3 gears, 9 models and 11 speeds, with "strong power, ultra smooth, long endurance, extreme fuel saving" four major advantages.
Specifically, the 3 engine represents 3 intelligent combinations of power sources; and the 3 gears have 3 physical gears with super high efficiency, which can cope with more working conditions; 9 modes are 9 working modes covered by the whole scene, including single/double motor drive, extended range, parallel, engine direct drive, single/double motor energy recovery, driving/parking charging 9 working modes; 11 speed means that 11 driving road conditions such as starting, low and medium speed, elevated, overtaking and other 11 kinds of driving road conditions can be intelligently switched. Chery's first models equipped with this hybrid technology include Xingtu's Wind Chaser and Tiggo 8 PLUS Kunpeng e+.
Gilli Ray Divine Intelligence Hi · X At the end of last month, Geely Auto officially released the Thunder God Intelligence Engine Hi · X。 The hybrid series includes a 1.5T/2.0T hybrid engine and a DHT/DHT Pro (3-speed transmission) hybrid special transmission, which supports full coverage of A0-C class models, and also covers a variety of hybrid technologies such as HEV, PHEV, and REEV.
Among them, the thermal efficiency of this 1.5TD hybrid special engine is as high as 43.32%, and the fuel consumption of 100 kilometers is about 3.6L. As Ray's Mind Hero X's other core, dhT Pro is the world's first mass-produced 3-speed hybrid transmission, with light weight, high torque, and can achieve hybrid system FOTA upgrades. Ray's Mind Hi · Shortly after the X hybrid platform was released, the first model was the Hoshigoku L Thor Hi· X, before the listing of a endurance challenge, someone ran a terrible 1426.1km endurance performance. It can be predicted that as geely's core intelligent hybrid platform and core power unit, most of Geely's models will be equipped with hybrid systems under the platform in the future.
epilogue:
BYD, Great Wall, Changan, Chery and Geely, as the leaders of independent brand car companies, have their own advantages in developing hybrid technologies. Their respective products are also carrying their own magic weapons. BYD Qin Plus DM-i, Song Plus DM-i and other products, there will be Han DM-i in the future to make up for the DM-i camp, in short, BYD This hybrid system will not iterate in a short time, and will be covered nationwide in the Dynasty car series. Great Wall Motor put this hybrid DHT system on the Wei brand SUV, representing the Macchiato DHT PHEV and the upcoming Mocha DHT PHEV. Chang'an's UN-K PHEV, Chery's Tiggo 8 PLUS Kunpeng e+, Geely's Hoshikoshi L Thor Hi· X and so on. In the future, the hybrid system will continue to iterate and upgrade, how is the system performance of each main brand? That also depends on the specific performance of the sales of its models. Which hybrid system would you choose?
