In addition, Dongfeng Motor has also launched the Mach E new energy power brand and the "Dongfeng hydrogen boat" hydrogen power brand. CTOnews.com selected a few official texts to introduce.

Mach E is mainly composed of electric drive, battery and energy supplement product platform, with four bright spots of "extreme fusion, high efficiency and high speed, surging power and intelligent control". It integrates more than 20 industry-leading technologies, and the motor using carbon fiber coated rotor technology has a rotational speed of up to 30000 rpm. Matched with the self-developed SiC controller, the highest efficiency of the system can reach 94.5%, achieving "high speed and high efficiency".

Mach electric drive adopts flat line motor with power covering 70-400kW and voltage covering 300-800V, which has formed a complete product matrix, which can meet the needs of different models. In the future, Dongfeng will also focus on the three dimensions of "kilovolt drive, wide-area speed regulation and full stack efficiency" to launch better products.

Mach battery has the product characteristics of "long life, high safety, ultra-fast charge and extremely smart". Mach battery uses the industry's original CIS efficient grouping technology, with a grouping efficiency of more than 80%, a system energy density of more than 300Wh / Kg, and a mileage of more than 1200 km with a full vehicle CLTC. The Mach battery adopts L300 standardized hard shell cell design and can pass the industry's most stringent 20mm deep acupuncture test. The use of "high strength aluminum alloy frame, bottom armor" to achieve "military vehicle armored class" structure protection, can reduce the core temperature within 1 minute by 80 ℃, to achieve "high safety". In terms of fast charging, it can be recharged for 5 minutes and has a range of 300 kilometers.

In the field of power exchange, Dongfeng pioneered T-type rotary power exchange mechanism, flexible positioning structure and long-life liquid-cooled power exchange interface, which takes only 90 seconds and achieves more than 10000 times of life. In the future, based on the concept of open and shared service, we will create a leading shared power exchange technology platform in the industry. In the charging field, Dongfeng has mastered 3X global charging technology, including mass-produced AC charging, DC charging, super fast charging and advanced charging technologies being pre-developed, such as wireless charging, automatic charging, V2G, solar charging and so on.

Mach Power has fully covered the three major fields of energy-saving power, hybrid power and pure electric power. The era of Mach "core" has come, which will help China Power Science and Technology to climb another high-rise building.

Hydrogen boat includes two sub-brands: Dongfeng hydrogen fuel cell system and Dongfeng hydrogen core fuel cell stack. The Dongfeng hydrogen autonomous fuel cell system is composed of hydrogen supply, gas supply, hydrothermal management and other systems, and the Dongfeng hydrogen core autonomous fuel cell stack is composed of membrane electrodes, bipolar plates, catalysts and other core components.

Dongfeng hydrogen Boat is driven by application scenarios, with layout of 70kW, 150kW and 350kW hydrogen power platform products, power coverage of 20kW-350kW. Among them, 350kW is the leading high-power platform in China, which can meet the needs of a full range of passenger vehicles and commercial vehicles, and achieve full power, full-system vehicles, full scene and full coverage.

Dongfeng hydrogen Yuan adopted a highly integrated development mode, invented the connection of the stack and high-voltage devices, efficient energy recovery, waste heat utilization, and high dynamic response technology, and formed a gas, water, heat, and electricity cooperative control system, with a system efficiency of 63%. Reached the industry-leading level; invented hydrogen cycle, hydrogen concentration multi-objective strategy, hydrogen utilization rate as high as 98%, to achieve efficient and economical use of the whole life cycle.

Dongfeng hydrogen core, through the integration of electrochemical technology, control technology, manufacturing technology, digital technology and 4T technology, builds the commanding heights of fuel cells and provides users with high-quality products with "ultra-long durability and reliable life cycle". Dongfeng hydrogen core has gone through the extreme working conditions and durability verification of the whole scene, and has overcome the harsh environmental tests such as-40 degrees fast cold start for 30 seconds and 4000 meters above sea level, creating excellent quality and providing customers with full life cycle protection.
