This model will be equipped with a new model of lemon hybrid DHT technology. First of all, talk about lemon mixed DHT technology. This system architecture can be summarized as "1-2-3", which means a highly integrated DHT hybrid system, with two power forms of HEV/PHEV, and three different types of vehicle powertrains. This high-efficiency multi-mode hybrid powertrain integrates 1.5L/ 1.5T hybrid engine, generator/drive dual-motor controller, DHT module (fixed-axis gearbox), integrated DCDC (direct current converter) and high-efficiency hybrid battery.
As the first mass-produced HEV model of WEY brand, the model we are talking about today is expected to be equipped with a 1.5L hybrid engine, with a maximum net power of 7 1kW and a highly integrated hybrid gearbox 100kW. The comprehensive power of the system is 140- 170kW, and its fuel consumption level is expected to be as low as 4.7L/670 kW. In addition, the highlights of this 1.5L engine are Atkinson cycle, external water-cooled EGR and other technologies, and the compression ratio is as high as 13: 1.
1.5L engine is also outstanding in design, with a highly integrated design. Compared with the traditional fuel system assembly, it has smaller volume, lighter weight, higher transmission efficiency and better NVH performance. The dual-motor series-parallel topology can realize EV drive, series drive, energy recovery, idle stop and other working modes, and can be intelligently switched through the control system.
The power generation/driving of dual-motor hybrid topology can be regarded as the "central brain" of lemon hybrid DHT. The adaptability to complex working conditions and excellent dynamic processing ability are the "foundation" of this structure, which can realize various working modes such as EV drive, hybrid drive, series drive, energy recovery and idle stop. Through a new generation of high-computing Infineon TC38 series processor chips and the control algorithm independently developed by Great Wall Motor, the energy flow of the system is intelligent.
DHT module can be understood as the "transmission device" of lemon hybrid DHT, including reducer, clutch, gear shifting mechanism and dual motors. The design of double electronic pumps can adjust the start and stop of electronic pumps according to the needs of the whole vehicle. Single clutch design, compared with double clutch, has lower requirements for lubrication and cooling. And the structure is very compact, which is more than 50% lower than that of traditional DCT.
High-specification power battery is also the core component of lemon hybrid DHT. HEV will be equipped with high power and low internal resistance battery, super power 1.7kWh, advanced silent air cooling technology, discharge power of 70.9kW, and 8-year warranty 1.5 million km. For PHEV four-wheel drive vehicles, the energy density of the power battery exceeds 160Wh/kg, which can provide a pure electric cruising range of up to 200km. In charge and discharge, 1 1kW AC charging power supply and DC fast charging are supported, which can charge 80% in 30 minutes and the maximum discharge power is 246kW.
It should be mentioned that in EV working mode, the wheels are directly driven by the driving motor. In the series working mode, the engine drives the generator to generate electricity, and the motor directly drives the wheels, which is mainly used to deal with the urban road conditions with medium and low speed and stop-and-go. In parallel working mode, the wheels are directly driven by the engine, and the generator and driving motor are responsible for adjusting the engine working point and auxiliary driving wheels, which is suitable for high-speed driving conditions. Moreover, it also has an energy recovery mode, in which the energy is recovered by the driving motor and the excess energy is recovered in the braking state.
After talking about its lemon hybrid DHT, let's take a look at the appearance of this model. The appearance of the new car continues the overall design style of Mocha, and the large hexagonal air intake grille is decorated with chrome-plated mesh structure. Although it is different from WEY's current model, this design is quite satisfactory. In the part of the lamp group, the vertical elements of the family are integrated into the lamp cavity, and the overall shape is not separated from the shadow of the VV family; The front enclosure adopts trapezoidal air inlet design and is wrapped by a large-size guard plate. The whole front face looks tough and highly recognizable.
The side of the car body looks more like a shortened version of Mocha, with a sliding roof design. The overall design is not strong and too conventional. In terms of dimensions, the length, width and height are 4520/ 1855/ 1665mm, and the wheelbase is 2710 mm. In addition, the tire dimensions of the new car are 2 15/60 R 17 and 225/55 r/kloc.
The rear of the car still adopts a simple and full design style, which is very compatible with the VV family models and has not undergone drastic changes. The back wall has been redesigned, wrapped with large-size black guards, and the inverted L-shaped guards on both sides look very three-dimensional. In addition, the new car still adopts a hidden exhaust layout.
The interior part has not disclosed any information at present, but from the previous WEY family models, it is expected that the new car will adopt the same interior style as Mocha, but it will be slightly adjusted in configuration and details. Let's look forward to whether its interior will surprise us.
Finally, talk about the birthplace of this model, "Rizhao Smart Factory"? (Rizhao Wei Yi Automobile Co., Ltd.), which is also the birthplace of WEY brand's first HEV model. With a registered capital of RMB 2 billion, Rizhao Wei Yi Automobile Co., Ltd. is a wholly-owned subsidiary with independent qualification of R&D, vehicle and parts design, production and manufacturing. At present, Rizhao Wei Yi Automobile has four workshops: stamping, welding, painting and assembly, followed by interior and exterior decoration, seats, chassis and other parts workshops. ?
In addition, Rizhao R&D Center, which matches its planning, integrates R&D design, trial production, quality control, collaborative development and technical pre-research, and has internationally advanced vehicle R&D center, modeling center, artificial intelligence laboratory, new energy fuel cell R&D center and powertrain laboratory. Based on the introduction and development of intelligent manufacturing equipment, the automation degree of the production workshop of Rizhao Wei Yi Automobile Co., Ltd. can reach more than 75%. Rizhao Smart Factory and Rizhao R&D Center, one of the nine bases of the Group, are Baoding, Xu Shui, Tianjin, Yongchuan, Zhangjiagang, Zhejiang, Pinghu, Taizhou, Jiangsu and Jingmen, Hubei. They are mainly responsible for WEY brand product research and development and technical breakthrough tasks, and help brands build global production layout.
Summary: From the above information, it can be clearly understood that the new SUV Macchiato is the first HEV model under WEY brand, and the technology of this hybrid system is indeed ahead of the hybrid technology currently on the market, especially in pure electric mode, its instantaneous explosive power is also stronger, and the initial hybrid has achieved a perfect balance between fuel efficiency and performance. But this macchiato is just showing up this time. The overall design is not divorced from the figure of the VV family, and the overall design is too conservative. If designers are bold and carry out personalization to the end, it will further attract young people now. However, this is not its bright spot. After all, this new car relies on the 5G network, focusing on intelligent driving, intelligent cockpit, intelligent service and HEV hybrid technology, further enriching the car scene and fuel economy.
