The outstanding product performance has also been recognized by industry experts and many major awards. Among them, the 1.5T lemon hybrid DHT system was successfully selected into the "China Heart" Top Ten Engines in 2021. This is also the eighth time that Great Wall Motors has won this award. Weipaina is equipped with a 1.5T hybrid special engine and a DHT130 lemon hybrid DHT system. Iron, with its 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. This was the fourth time that Great Wall Motors won this award. The Wei Macchiato equipped with this transmission also became the winning model in the selection. The top ten awards received successively have become a strong proof that Lemon Hybrid DHT’s technical advantages and product quality are widely recognized.

Dayu battery technology innovates battery safety with new design concept
In terms of pure electricity, Great Wall Motors released Dayu battery technology, which provides a solution to the problem of thermal runaway of ternary batteries with the design concept of "blocking is worse than sparing". Brand new ideas.
The actual test of the battery pack equipped with Dayu battery technology adopted the most stringent test conditions in its class. The battery core material was a high-nickel battery with the worst thermal stability. It was heated to 1037°C to cause the battery core to accumulate and trigger thermal runaway. , but Dayu battery technology still ensures that the entire battery pack will not catch fire or explode.
The ultra-high safety of Dayu battery technology stems from its own highly innovative safety design ideas. It takes "control + conduction = communication" as the technical principle, and adopts "heat source isolation, two-way commutation, The eight design concepts of heat flow distribution, directional detonation, high-temperature insulation, automatic fire extinguishing, positive pressure oxygen barrier, and intelligent cooling solve the safety problem of battery thermal runaway. At the same time, Dayu Battery Technology has pioneered the construction of a package-level thermal runaway combustion model to achieve multi-dimensional fitting simulation of air flow and fire flow, filling the industry gap and subverting the traditional method of developing first and then testing in the field of thermal runaway.
Dayu battery technology structure
At the same time, Great Wall Motors has also given full play to its sense of social responsibility as a leading Chinese automobile brand, and has transferred a number of Dayu battery technology core patents to It is free and open to the whole society, contributing to the continuous improvement of battery safety technology in the industry.
Dayu battery technology is open to the public for free
At present, Dayu battery technology has been used for the first time in the Salon’s first high-performance mecha battle runner-Mecha Dragon, realizing the transformation from technology to Rapid transition of products. Thanks to the blessing of Dayu battery technology, Mechalong not only ensures excellent safety performance of not catching fire or exploding at high temperatures of 1000°C, but also has a zero-to-zero acceleration of 3.7 seconds, a CLTC battery life of 802km, and the world's leading 800V/480kW high efficiency. Excellent performance such as energy replenishment technology and associated APA wireless charging function bring the performance of electric vehicle products to a new high.
