Lemon hybrid DHT breaks the monopoly of joint venture brands
Hybrid technology is more mature in the current vehicle electrification technology route, and it is also an important development path to achieve the goal of decarbonization. At the end of 2020, Great Wall Motors released the first dual-motor hybrid hybrid architecture product of a Chinese automobile brand, lemon hybrid DHT. As the world's first highly integrated, the only Chinese independent oil-electric hybrid technology that meets the global travel needs, the emergence of lemon hybrid DHT represents the long-term maintenance of the hybrid technology barrier of the joint venture brand by the Chinese automobile brand.
Lemon blend DHT
Compared with the general hybrid system, lemon hybrid DHT greatly increases the daily pure electric drive mode, and more than 98% of the scenes in the urban working conditions are pure electric drive. For different working conditions such as low speed, medium speed and high speed, the lemon hybrid DHT parallel axis two-speed hybrid architecture realizes the comprehensive and perfect performance of all dimensions without power interruption shift, ultra-quiet NVH and low fuel consumption, ensuring the performance and performance of the full speed domain and the whole scene. At the same time, the overall efficiency of the system can exceed 50%, the transmission system efficiency is the highest in the world of more than 98%, the C-class SUV products using lemon hybrid technology will be equipped with 45kWh large-capacity battery cells, the world's longest 204 km pure electric mileage, excellent energy conversion efficiency and the application of large-capacity batteries, completely solving the mileage and charging anxiety for consumers.
Thanks to the good adaptability and unique advantages of technology, many products equipped with this hybrid system are also rapidly landed in 2021, and the new generation of intelligent hybrid SUV Marchiato DHT-PHEV officially listed in November has a pure electric endurance of 110 kilometers, full fuel endurance of up to 1100 kilometers, comprehensive fuel consumption of 0.8L per 100 kilometers, and fuel consumption of 4.4L at a loss of electricity, bringing users a travel life of "lower fuel consumption, stronger power and more comfortable experience". The "new generation of smart cars" with the same price of oil and electricity, latte DHT, with excellent product strength and sincere surprise price, has launched a strong impact on the joint venture hybrid models in its market segment from both product strength and price. In addition, Haval H6S and Haval Chitu two models equipped with lemon hybrid DHT have been listed, which has also caused a strong hybrid storm in their respective market segments, attracting the attention of many consumers.
A new generation of intelligent hybrid Weipai Machido DHT-PHEV
The outstanding strength of product performance has also been recognized by industry experts and many blockbuster awards. Among them, the 1.5T lemon hybrid DHT system was successfully selected as the "Heart of China" 2021 Top Ten Engines, which is also the eighth time that Great Wall Motors has won the award, equipped with a 1.5T hybrid special engine with DHT130 lemon hybrid DHT system, with a good balance between power responsiveness and fuel economy, has been unanimously affirmed by many authoritative judges. Subsequently, the lemon hybrid DHT won the "World's Top Ten Transmissions" award, which was the fourth time that Great Wall Motors won the award, and the Weipai Machiduo equipped with this transmission also became the award-winning model in the selection. The double top ten awards that have been won have become a strong proof of the technical advantages of lemon hybrid DHT and the wide recognition of product quality.

Dayu Battery Technology Innovates new design concepts for battery safety
In terms of pure electricity, Great Wall Motors released Dayu battery technology, with the design concept of "blocking is not as good as thinning", which provides a new idea for solving the thermal runaway problem of ternary batteries. For the actual test of the battery pack equipped with Dayu battery technology, the most stringent test conditions of the same level are adopted, and the cell material uses a high-nickel battery with the worst thermal stability, which is heated to 1037 ° C to make the cell gather and trigger thermal runaway, but dayu battery technology still ensures that the battery package does not catch fire and does not explode.
The ultra-high safety of Dayu battery technology originates from its own innovative safety design ideas, taking "control + conduction = pass" as the technical principle, through the "heat source isolation, two-way exchange, heat flow distribution, directional discharge, high temperature insulation, automatic fire extinguishing, positive voltage oxygen resistance, intelligent cooling" 8 design concepts, to solve the battery thermal runaway safety problem. At the same time, Dayu Battery Technology pioneered the construction of a whole package-level thermal runaway combustion model, realizing multi-dimensional fitting simulation of airflow and fire flow, filling the gap in the industry, and subverting the traditional way of first developing and then testing in the field of thermal runaway.
Dayu battery technology structure
At the same time, Great Wall Motors also gives full play to its sense of social responsibility as the head enterprise of Chinese automobile brands, and opens a number of dayu battery technology core patents to the whole society free of charge, adding bricks and tiles to leading the continuous improvement of battery safety technology in the whole industry.
Dayu battery technology is free and open patent
At present, Dayu Battery Technology has been the first to build the salon's first high-performance mecha battle run - Mecha Dragon, realizing the rapid transition from technology to products. Thanks to the blessing of Dayu battery technology, on the basis of ensuring the excellent safety performance of 1000 °C high temperature no fire, no explosion, etc., the mecha dragon also has zero hundred acceleration 3.7s, CLTC endurance of 802km, the world's leading 800V/480kW high-efficiency energy supplement technology and related APA wireless charging function, etc., which will raise the performance of electric vehicle products to a new high.
