[October 18, 2017, Beijing] At IEEV China 2017, Qiantu Motor Company comprehensively put on display their core technologies and manufacturing process at their Suzhou manufacturing base. They revealed their manufacturing breakthroughs and achievements in the application of new materials such as carbon fiber and aluminum alloys, focused on lightweight body development which is a key technical difficulty in the manufacturing of electric vehicles. With the continuous development of China’s NEV industry, competition among NEVs is becoming increasingly fierce. Lu Qun, chairman of Qiantu Motor Company, said that, "The NEV industry must develop in a fully competitive market environment as a long-term trend. New entrants should have independently-developed core technologies and new manufacturing models based on such technologies. That's the only way to push the healthy development of the Chinese NEV industry and to create high-quality Chinese auto brands." Always putting users first, Qiantu Motor Company applies internet-thinking to the auto-making process in order to provide a customized service experience to their customers. Their Suzhou manufacturing center will be a fully digitalized, and open-concept vehicle manufacturing base. Customers are able to see the full manufacturing process of their ordered car through their website or APP. The Suzhou manufacturing base is the first base in China that enables large-scale customization and flexible production—adopting an order-driven production system, which means that once an order is received, a fast supply-chain response mechanism is activated to create quality products according to specific customer needs.
Centered on lightweight body development, Qiantu Motor’s Suzhou manufacturing base consistently drives innovation in manufacturing technology—such as introducing the most automated carbon fiber moulding production line in the world. This makes Qiantu Motor Company the first in China to enable the large-scale application of carbon fiber on mass-production vehicles. The Qiantu K50 has 29 carbon fiber parts that weigh only 46kg in total.
Moreover, Qiantu Motor Company has built the first full-aluminum-alloy frame production line in China, overcoming the industrial difficulties of thermal deformation in the welding of aluminum-alloy body frames. The aluminum-alloy frame of Qiantu K50 is 30% lighter than a traditional steel frame, and the lightweight structure comprising of a full aluminum alloy body frame and carbon fiber parts reduces the K50's total weight by 250-300kg.
True to their concept of "Evolution in Motion", Qiantu has never stopped its exploration in innovation. Their paint-free technology on display at the show is a car surface treatment technology developed by Qiantu Motor Company. It prevents paint pollution caused by the traditional painting process and makes the production eco-friendlier. A small number of products will roll off the production line at Qiantu's Suzhou manufacturing base at the end of this year, as part of their concrete efforts to support the national "Made in China 2025"plan for transforming China's manufacturing.
In addition to manufacturing technology, Qiantu Motor Company also displayed its achievements in EV battery, motor and electric control developments at the show. Its battery system uses liquid cooling technologies to ensure efficient battery operations in the temperature range from -30℃ to 45℃. As a result, driving range would be little affected by ambient temperature, avoiding drastic reduction of range in cold winter in northern China. Battery power consumption remained unaffected in the temperature range from -30℃ to -55℃ in thermostats exhibited at the booth. The Qiantu K50 with RESS (Rechargeable Energy Storage System) will hit the market in 2018.
