The past 2021 is known in the industry as the first year of domestic hybridization, almost all independent car companies are at this time "show" the hybrid technology of reserves, "engineering man" Chery is no exception, with the release of Tiggo 8 PLUS Kunpeng e+ is imminent, 3 engine 3 gear 9 mode 11 speed hybrid scheme can boost the new height of transmission efficiency? Just like technological innovations such as turbocharging, CVT, and dual clutch, hybrid solutions are also affecting the new direction of automotive technology in 2022 after the new energy policy is revised.
Chery DHT hybrid
1, 1.5T engine and dual motor 3 engine combination, the highest 510N·m maximum input torque, the maximum output torque also reached 4000N·m
2, 3 physical gears, the engine can also be based on the actual road conditions in the minimum intervention point of 20 km / h at the intervention acceleration
3. It has realized 9 high-efficiency working modes such as single/double motor drive, extended range, parallel connection, engine direct drive, single/double motor brake energy recovery, and driving/parking charging.
4. Achieve 11 combined gears, covering starting, low and medium speed, elevated, overtaking, red lights, congestion, high speed, long distance, mountain road, high speed steering, ice/mud/sand and other scenes
01
Dual motor combination drive + 3-speed physical shifting
Chery DHT hybrid system provides 3 intelligent combinations of power sources, the engine is the first to launch a 1.5T hybrid special engine, which can output a maximum power of 115kW and 230N·m plus "dual motor drive" motor layout, of which the power parameter of the P2 motor is 55kW /160N·m, and the parameter of the P2.5 motor is 70kW /155N·m, compared with the current hybrid technology, the advantage is that P2 can also provide power. In addition, the four-wheel drive model will also be equipped with a P4 rear axle motor, thus forming a four-engine four-wheel drive power mode.
In terms of transmission, the hybrid architecture has a 3-speed dual-clutch form, which can cope with the working conditions have been improved, and the 1-speed ratio setting is relatively large, mainly for starting and accelerating; the 3-speed ratio is relatively small, so that the vehicle speed and fuel consumption are at a low level, and the noise can be reduced. The emergence of the 2-speed ratio has played a role in carrying up and down, ensuring the smoothness of the gear change, while taking into account fuel consumption.
02
9 operating modes + more flexible gear combinations
Due to the different working conditions of driving, the supermix system can match the whole vehicle to achieve 9 working modes such as single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, and driving charging. More flexible gear combinations can handle a variety of car scenarios, including starting, low and medium speed, elevated, overtaking, red lights, congestion, high speed, long distance, mountain trails, high speed steering, ice/mud/sand, etc.
Chery's DHT hybrid system will be the first to be installed on the Tiggo 8PLUS Kunpeng e+, which is expected to be officially released on January 14, according to Chery's official planning, and then fully rolled out on Allied, Tiggo 5X and other models.

postscript
At present, the hybrid technology of major car companies has shown a new height of data, especially for the Chinese people's car habits, scenes are more thoughtful, before the era of pure electricity really comes, borrowing the logic of electric drive assistance, the transmission efficiency of fuel vehicles has been further upgraded. Of course, the more complex the technology, the more it needs to be tested in actual use, and standing in this "hybrid first year" we are waiting to see.
