In today's era of expensive oil prices and rising trams, plug-in hybrid technology seems to be one of the best solutions, and because of this, more and more consumers are looking at plug-in hybrid cars.
Last year in the 2021 domestic hybrid market, the most able to play the C position is undoubtedly BYD, its DM-i model cumulative orders of more than 150,000 units, with the bydir plug-in hybrid system hot sales, other car companies have also kept up with the pace, launched their own plug-in hybrid models, of which Geely's Thor HIX super hybrid system is one of them.
Just last month Geely launched the Emgrand L Thor Hi · X, its main competitor is BYD Qin Plus DM-i model, today Xiaobian through the hybrid system equipped with these two cars to compare for everyone, Geely's thunder god Hi · What is the difference between X and BYD DM-i, which is stronger or weaker.
1. BYD's DM-i
BYD's DM-i hybrid technology is the earliest of the five hybrid technologies installed in the mass production model of the hybrid technology, BYD DM-i hybrid technology focuses on battery technology, this is because BYD is a battery start-up car manufacturer, in the past two years BYD's blade battery is more famous.
The core of BYD's DM-i hybrid system is the EHS super hybrid system, which consists of a seven-in-one highly integrated motor, a 1.5L/1.5T Snapdragon dedicated high-efficiency engine, a dedicated high-efficiency blade battery and a vehicle control system.
DM-i hybrid technology breaks the traditional engine as the main power output mode, with the motor as the mainstay, the engine as a supplement, with BYD's self-produced blade battery to provide power to the car, which makes the engine from only as a power transmission role to in addition to providing power to the car, but also to the battery and motor to provide power that can drive the car. The Xiaoyun 1.5L plug-in hybrid special engine eliminates the traditional wheel train and has an ultra-high compression ratio of 15.5:1, which can achieve a thermal efficiency of 43% under ideal conditions.
The two ultra-high speed motors of the EHS system are designed in parallel, with the generator directly connected to the engine, and the clutch and reducer are connected by a reduction gear. The drive motor is directly connected to the reducer via a reduction gear. Simple reducer architecture greatly improves transmission efficiency, BYD DM-i uses single-stop direct drive, which will make the running quality of the vehicle more smooth and stable and smooth, while BYD's DM-i hybrid technology has passed the verification of many models, of which Qin plus DM-i is equipped with a DM-i hybrid system with a 1.5 naturally aspirated engine.
2, Gilly Thor Hi · X
It is understood that Geely in the Thunder God Intelligence Qing Hi · In the process of research and development of X hybrid system, the new energy laboratory with the largest investment scale, advanced equipment and most complete functions in China was called - "Geely New Energy Power Test Center", which gave Geely a strong self-research ability.
Gilli Thor Hi · X integrates a 1.5TD hybrid special engine, DHT Pro (3-speed transmission) hybrid special gearbox, is a product covering hybrid, plug-in and range extension and other technologies, its biggest highlight is 43.32% thermal efficiency, this data is currently the world's highest, more than BYD DM-i hybrid system 43.04%.
Geely Emgrand L Thor Hi · The X engine is fully equipped with a 1.5TD turbocharged engine, which far exceeds the 1.5 naturally aspirated engine on the competitor Qin Plus DM-i in terms of engine power, which produces more rapid power and reserves more power.
It is worth noting that Geely's DHT Pro (3-speed transmission) hybrid special gearbox, compared to BYD DM-i's single-speed transmission, Geely's 3-speed transmission can release more torque through gear adjustment, which makes the zero-hundred acceleration of the Geely Emgrand L Raytheon hybrid model nearly 1 second faster than the Qin plus DM-i, and in the case of faster speed, the 3-speed transmission can reduce the engine speed relatively, which is conducive to the performance of the vehicle NVH.
If you think 3 gear is better than a 1 gear gearbox, it may be a bit one-sided. Although the 3-speed transmission can release more torque and make the acceleration more direct, but at the same time, the gear shift will also make the vehicle more or less shifting during the acceleration process, at this point, the BYD DM-i single gearbox will be more smooth than the Thor due to the lack of shift action.
In addition, in the later maintenance, DM-i's single-speed transmission is more convenient because of its simpler structure, more convenient maintenance, and lower maintenance costs.
Summary:
In summary, BYD DM-i and Geely Raytheon have their own advantages in the hybrid system, relatively speaking, the technology of Geely Raytheon is more advanced, but BYD DM-i, as the forerunner of the hybrid system, has withstood the test of the market. And The Gilly Thor Hi · X has just arrived, and if the follow-up can maintain the momentum, it will also be a member of the market segment.
