Following BYD DM-i and Great Wall DHT, on January 12, Chery Automobile also released the brand's latest super hybrid "black technology" - Kunpeng DHT Super Hybrid Platform (hereinafter referred to as Kunpeng DHT), indicating that the domestic hybrid "three brothers" have arrived.
The first model equipped with this hybrid system is chery brand's current hot-selling SUV Tiggo 8 PLUS, on the green card, will be announced on January 14, the first price and rights.
First of all, bright data!
According to the official information, the Tiggo 8 PLUS Kunpeng e+ equipped with this Kunpeng DHT includes a hybrid special 1.5T engine, a front axle dual motor, and a rear axle motor. With the TSD dual-shaft drive module, the vehicle 0-100kmh/ acceleration time is less than 5s (four-wheel drive version), 0-100km/h acceleration time 7s (two-wheel drive version).
At the same time, the green brand of Tiggo 8 PLUS Kunpeng e+ is also equipped with a large-capacity lithium battery pack, which supports a pure electric endurance of 100km; the fuel consumption under comprehensive working conditions is as low as 1.0L/100km, and the comprehensive power loss fuel consumption is only 5.0L/100km.
How exaggerated is this statistic?
First of all, the power performance, you can simply compare the pure fuel vehicle, most of the household SUVs of the same level are basically pure front-drive, even if it is a 2.0T engine, it is very "violent" to do 8 seconds to break the hundred, and to do 5 seconds to break the hundred, equipped with 3.0T + 8AT + AWD Audi Q7, BMW X5 are enough.
Then there is the fuel consumption, this level of fuel vehicle (2.0T) fuel consumption in 9-10L/100km is a relatively normal average standard, and Tiggo 8 PLUS Kunpeng e + even if the whole process is not charged, its power loss and fuel consumption compared to pure fuel vehicles are also directly "5 discounts", and do not pick road conditions, fuel consumption is low and stable.
Large capacity lithium battery pack
No motor on the front drive, rear axle
All-wheel drive, rear axle has an electric motor
Finally, the battery, the national standard on the plug-in mixed car green card requirements is 50km + pure electric endurance, and this price of domestic plug-in hybrid lithium batteries are getting bigger and bigger, pure electric endurance has begun to move closer to 100km, this Tiggo 8 PLUS is one of them, and is the groundbreaking standard of the whole series.
To achieve such results, its technical core is this full-featured hybrid configuration Kunpeng DHT platform, with 3 engines, 3 gears, 9 modes, 11 speeds, which can meet the user's full-scene needs in multiple dimensions such as performance, smoothness, fuel consumption and NVH.
The engine part is still the Chery 1.5TCI engine (hybrid special type) that we are familiar with, but what matches it is not a combination of hydraulic torque converter and CVT transmission, but a set of electric drive modules composed of two motors and TSD biaxials, and the two motors in the front axle part of Kunpeng DHT have different functions under different modes and gears, which is also the technical core of Kunpeng DHT.
Where the EM1 motor is located
Among them, the EM1 motor that is closer to the engine is an integrated disc motor (axial magnetic flux), the torque density and power generation efficiency are very high, this motor is mainly electromechanically coupled with the engine on the left side, maintaining the speed /load stability of the latter, parking, downhill engine braking and other working conditions of the charging also depends on it. At the same time, the motor can also output power in pure electric or hybrid mode via the clutch.
Where the EM2 motor is located
Another EM2 motor farther away from the engine is a radial flux motor, in the form of a flat wire winding, with greater power density and a very high energy conversion efficiency (from electrical energy to kinetic energy) at a stable speed.
This motor can directly drive the front axle half shaft through the three-stop gearset and reducer, rely on TA in single electric drive pure electric mode, and can also form dual motor pure electric mode and hybrid performance mode through the gear set and clutch of the TSD dual shaft, and the engine EM1 motor above.
TSD dual-shaft drive module
Thanks to the presence of the TSD twin-shaft drive module, the engine can be accelerated at a minimum intervention point of 20 km/h according to the actual road conditions, providing low-speed explosive force.
At the same time, the tube is a single motor pure electricity, dual motor pure electricity, or engine direct drive (in fact, it is also hybrid) and three-engine performance mode, the external output of the power system will be optimized through the balance of speed / power / torque through three gears, so that the whole vehicle in the full speed range, the whole working conditions can achieve performance and fuel consumption, which is difficult to do without a transmission peers.
9 speed 11 model overview
Finally, Chery also equipped this Tiggo 8 PLUS Kunpeng e+ with A P4 bridge, electric four-wheel drive we should be more familiar, Volvo Drive E T8, Toyota THS e-four, BYD DM-power have been used, its biggest feature is that it does not need a central drive shaft to achieve electric drive, and the power output of the rear axle can be directly controlled by the electronic control system, high transmission efficiency, fast response speed.
Summary
As a national new energy technology project, kunpeng DHT super hybrid platform represents Chery Automobile's latest understanding of high efficiency/strong power hybrid system, the unique TSD dual-axis drive module makes the system in all scenarios and multi-dimensional comprehensive performance, but also realizes the independent control of Chinese car companies on the key core technologies of hybrid, which is also an important development direction and core competitiveness of future passenger car electrification.
