How to improve the cruising range of new energy vehicles? One of the most effective methods is to increase the energy density of its battery system. From tracking research and imitation to independent innovation, China's lithium-ion battery industry technology has developed rapidly.
On January 8, energy technology companies held a new product launch conference in conjunction with Tianyi. At the meeting, Linkage Tianyi officially launched the 26-46mm cylindrical family, that is, the SPEED series fast-charging power battery, with a diameter covering 26mm-46mm.
At the meeting, Yang Sitao, vice president and chief technology officer of Linkage Tianyi, demonstrated the latest product research and development achievements: including the previously announced SPEED2 series with a diameter of 26mm, as well as the newly released SPEED3 and SPEED4 series.
The SPEED3 series with a diameter of 37mm released by Linkage Tianyi has a higher energy density than the 26mm SPEED2 series lithium battery, and its comprehensive performance is relatively balanced, which is suitable for high-end passenger cars.
SPEED4 series lithium batteries simplify the corresponding system integration, reduce cost, improve comprehensive performance, suitable for ordinary family cars.
In September 2021, Linkage Tianyi released the fast-charging power battery series - SPEED, whose cell cell energy density reaches 260Wh/kg, and the current charging 8 minutes can reach 400 km endurance, and the number of fast charging cycles can reach 800~1200 times. It is expected that by 2025, the charging time will also be shortened to 5 minutes.
The cylindrical/square cells of the SPEED series are high nickel chemical systems, and after the cell monomer level is formed into a module/system, NTP (no thermal runaway) can be achieved.
It is reported that the SPEED fast-charging power battery will be fully mass-produced in 2023, providing related lithium battery products for the global electric vehicle market.
Linked Tianyi New Energy Industry Base is located in Jiangyin High-tech Zone, and its products are widely used in new energy vehicle battery systems, energy storage systems and other new energy businesses.
Yiou Automobile learned that Linkage Tianyi has many years of mass production manufacturing experience and fast charging core research and development experience of cylindrical and square batteries, and has obtained hundreds of patents. At present, Linkage Tianyi has experience in in-depth customized development with a number of international OEMs, and the official said that it will continue to invest in the positive development of lithium batteries.
In the context of energy transformation and transportation emission reduction, green logistics is the way to go. On the same day, Yuandong New Energy Vehicle, a new energy heavy-duty truck brand founded and invested by Lianyi Tianyi, was also officially launched in Shanghai Center.
At this press conference, Ma Deren, CEO of Yuandong New Energy Vehicle, gave a detailed introduction to the newly created brand.
He said: "Yuan" represents the origin of all things in heaven and earth, has the meaning of beginning, grandeur and excellence, represents the brand spirit of Yuandong's ideals and innovation, and creates a new energy heavy truck technology "meta-universe"; "Moving" represents the transportation industry and new energy power. Yuandong New Energy will be committed to promoting the electrification and intelligence of heavy-duty truck models, and is committed to creating a new ecosystem of integrated logistics for new energy intelligent heavy-duty trucks.
Looking at the heavy-duty truck market in 2021, the rapid drive of electrification can be described as a major highlight, and the development of new energy heavy-duty trucks is inevitably inseparable from the country's goal of achieving "carbon peak and carbon neutrality".
China's traditional fuel heavy trucks and construction machinery have more than 15 million units, high fuel consumption, heavy pollution, the annual fuel consumption is equivalent to 200 million cars, pure electric heavy truck market in the government policy support has now entered a period of rapid development.
It is reported that Yuandong New Energy will take into account the design requirements of vehicle products based on the 6x4 semi-trailer tractor, build a universal electrification platform for new energy models EHDT, and develop serialized vehicle products on the platform.
Yuandong New Energy will use vehicle control technology, electric drive technology, intelligent technology and charging and replacing technology and other capabilities, the product will adopt low energy consumption engineering technology, including low wind resistance front, lightweight body and efficient transmission system, L4 intelligent cockpit, pure electric and hydrogen fuel cell hybrid, as well as automatic power exchange and super fast charging system.
It will also use a quick power swap mode to make up for the shortcomings of some charging modes. It is equipped with adaptive high beam illumination system, dynamic steering system, multi-directional imaging system, and AI energy management system.
In terms of the core founding R&D team, Yuandong New Energy will work with global partners such as China Automobile Research Institute, Huawei, Huaneng Group, and Bosch to carry out research on intelligent manufacturing solutions. In addition, the company has also built a platform for communication with well-known Chinese and foreign experts in the industry, and plans to build special research and development centers such as super fast charging systems, electric drive systems and AI in Germany, Japan and the United States to open up new positive development ideas and international product development processes.
Yan Zidian, the founding investor of Yuandong New Energy - Chairman of Lianyang Tianyi, said at the press conference that Yuandong New Energy, as a new force for clean energy heavy trucks, will actively respond to the national carbon neutrality and carbon peak policies, and steadily lay out the new market of transportation logistics and energy.
From low-carbon living to the dual-carbon goal, a broad and profound economic and social systemic change is taking place. As the main source of fossil fuel emissions, the logistics and transportation industry shoulders the important mission of energy conservation and carbon reduction.
The emergence of Yuandong new energy has undoubtedly injected new vitality into the era of electrification of smart heavy trucks.
