"Lemon Hybrid DHT" is a high-integration, high-efficiency and multi-mode hybrid power system. It adopts the series-parallel hybrid technology of two motors, which can achieve the balance between high efficiency and high performance in full speed domain and whole scene. This system includes 1.5L+DHT 100, 1.5T+DHT 130, 1.5T+DHT 130+P4, and HEV and PHEV.
In terms of parameters, the DHT system integrates 1.5L/ 1.5T hybrid special engine with high thermal efficiency, with a maximum power of 102 HP ~ 156 HP and an integrated driving motor power range of 136 HP ~ 177 HP.
On the basis of 1.5T, this powertrain adds a rear motor to realize four-wheel drive. One more motor means one more power, and the acceleration of 0- 100 km/h can reach 5.2 seconds. In the future, it will be mainly used for transverse engine models with higher level than Haval H6, such as the brand-new 7-seat SUV of Great Wall and larger luxury SUV.
The dual-motor HEV architecture pays attention to economy, the comprehensive efficiency of power system is 43-50%, the comprehensive fuel consumption per 100 kilometers can reach 4.6L, and the HEV battery pack1.8kwh; ; The PHEV architecture is equipped with a battery of 13~45kWh, and the official said that the maximum cruising range of pure electricity can reach 200km. It is reported that the manufacturer will also provide an eight-year warranty of 654.38+0.5 million kilometers for HEV/PHEV batteries.
At the driving level, lemon DHT technology will be completely driven by battery when the vehicle starts, which avoids the disadvantage of high fuel consumption in the initial stage of fuel vehicle. When driving at low speed between cities, vehicles will run in series, and the engine will generate electricity to transmit energy to the battery, and then the motor will directly drive the vehicles. At this time, the engine is only used for power generation, and the average speed is maintained, that is, the fuel truck always runs at a constant speed to ensure low fuel consumption; When driving at high speed, the vehicle will be directly driven by the engine, and the motor will play an auxiliary role, which makes good use of the energy consumption advantage of the fuel engine when driving at high speed; Finally, kinetic energy recovery, when the driver takes braking or oil collection, the system stores the recovered excess energy in the battery, which can be used as a driving motor while starting and assisting driving.
Recently, China Automotive Engineering Society released "Technology Roadmap 2.0 for Energy-saving and New Energy Vehicles", which clearly stated that traditional vehicles would be fully "mixed" in 2035. Even after 15, hybrid power will become the dominant force in non-new energy vehicles. From the promotion of pure electric vehicles to the vigorous promotion of hybrid electric vehicles, energy conservation and emission reduction are on the one hand, consumer demand is on the other hand, and more importantly, technical barriers account for the main reason.
Consumers choose new energy more because they don't have to shake the number, and they don't have to reduce or exempt the purchase tax. In fact, new energy sources do have big problems, especially the most critical battery technology is immature, and there has been no breakthrough for so many years. Now that subsidies for electric vehicles are declining, hybrid power is likely to break out. In the past, we were limited by technology. Now the Great Wall has its own hybrid system-lemon hybrid DHT. I believe that with the emergence of new benchmarks, other China automobile brands will catch up quickly, and the breakthrough of hybrid technology is just around the corner.
