Julang hybrid GMC2.0' s first SUV em koo Shadow Cool was officially unveiled. According to reports, GAC Chuanqi will also launch hybrid models of Shadow Leopard and M8 one after another.
| It has two hybrid technology routes of GMC/ Toyota THS independently developed.
According to the official introduction, Chuanqi has experienced 13 years of technical precipitation, and through open cooperation and independent research and development, it has become the only automobile enterprise with dual hybrid technology route in China.
There are two technical routes for giant wave hybrid: one is GMC dual-motor series-parallel hybrid system independently developed, and the other is THS power split hybrid system in cooperation with Toyota to realize the combination of turbocharged engine and THS system.
| GMC hybrid system: 2.0ATK engine +GMC2.0 electromechanical coupling system
GMC hybrid power system adopts series-parallel system, which has five advantages of "high quality, low fuel consumption, strong power, quieter and super smooth". Strong expansibility, covering oil-electric hybrid, plug-in hybrid and even hydrogen power system, covering full hybrid scenarios.
GAC 2.0ATK high efficiency Atkinson engine is a hybrid engine, which adopts GAC GCCS high efficiency combustion system, low friction design, waste recycling system, intelligent thermal management and noise reduction design, and its thermal efficiency is 42. 1%. The Atkinson cycle of the engine can achieve the ultra-high mechanical compression ratio of 15.6, and it is equipped with 350bar high-pressure direct injection system and electric intake VVT technology.
GMC2.0 electromechanical coupling system is upgraded on the basis of the first generation product, with better performance. GMC hybrid power system has more than 400 core patents (invention patents account for 57%) and more than 740 extended patents. The system makes the thermal efficiency utilization rate of hybrid power system ≥ 95.5% under WLTC working condition; AT the same time, the first integrated dual-motor dual-speed DHT is adopted, and the shift is more flexible because of the AT shift.
GMC hybrid power system * * * has four working modes: pure electric mode, in which the vehicle is driven by a driving motor, which is usually used for vehicle starting and high SOC conditions; Series (extended range) mode, the engine drives the generator to generate electricity and drives the motor to drive the vehicle, which is usually used in low SOC and low speed working conditions, such as urban driving conditions; In parallel mode, the engine and the driving motor jointly drive the vehicle, and the generator can generate electricity or drive as needed; The engine can switch between two gears according to the vehicle speed, so as to achieve the best working point and system efficiency. This mode is usually used in medium and high speed, high speed cycle and other working conditions; Energy recovery: the driving motor is used to recover braking energy and charge the battery, which is usually used under braking conditions;
In addition, it is worth mentioning that the system has a full-speed, all-field intelligent energy management strategy: the purpose is to intervene and optimize the working state of the existing power system in advance, especially the adjustment of the working mode of multiple power sources and the energy flow distribution state of the hybrid power system, through the real-time road conditions and traffic flow information of vehicle navigation and high-precision maps, so as to optimize the driving performance, economy, comfort, safety and convenience of use of the hybrid electric vehicle on the actual road. For example, real-time power planning in congestion: vehicles adjust power planning in real time according to the congestion degree of road congestion scenes, reduce engine intervention in congestion, and improve the driving comfort and economy of users in actual congested roads.
The battery of GMC hybrid power system adopts high-efficiency direct cooling technology and low-temperature self-heating technology, which has the characteristics of high power. The peak discharge power of the battery can reach 70kw at 10 second (i.e., 70kW can be discharged 10 second in the temperature range of 25-40℃, above 50%SOC).
| THS hybrid system: 2.0TM engine+Toyota fourth-generation THS hybrid system.
We are very familiar with the THS hybrid system cooperated with Toyota, which has been applied to the second generation Chuanqi GS8. The second-generation GS8 twin-engine series equipped with Toyota's fourth-generation THS hybrid system accelerates for 6.9 seconds, and a tank of oil can run more than 2022 kilometers (limit test I temperature 10-25℃ I tire pressure 2.8bar), and its excellent performance has been verified.
