·New energy bus reproduces two-way vehicle service Yutong quality strength

In March of Beijing, the annual national "two sessions" are being held. As a passenger car product that undertakes the mission of the two associations, Yu universal safety and quality are carrying the guarantee task for this event.
This year is the 13th consecutive year of service for Yutong Bus. With the increasing pressure on domestic environmental protection, people are increasingly demanding low-emission travel. In the past two years, there have been pure electric buses in the venues of the two conferences. This product is Yutong E10.
As a leader in the passenger car industry, Yutong has always adhered to the strategic development of technology development and planning, and always adheres to the “proactive, systematic (systemic), customer-oriented” PSC. "The Law of Innovation" provides insight into user and market needs and translates user needs and aspirations into innovations.
Yutong adheres to the strategic development of technology development and planning, starting from the national policy orientation and the status quo of new energy bus technology, based on domestic and international technological development trends, market research data, internal and external expert opinions, etc., in accordance with safety, comfort, energy saving, environmental protection, light The technical directions such as quantification and intelligence have respectively formulated development plans and clarified the route for the development of new energy bus technology. Established a technological innovation management system from product planning, research and development, technology, process, verification to trial production and a market-oriented, scientific and efficient product development system, forming a scientific matrix management structure, providing institutional guarantee for technological innovation. .
Under the strong support of national policies, Yutong Bus adheres to independent innovation, actively undertakes scientific research projects, attaches importance to talent introduction, and is committed to the research and development of new energy core technologies. Yutong took the lead in establishing the first “post-doctoral scientific research station” in the industry. It was recognized as the “National First Innovative Enterprise”, “High-tech Enterprise”, “National Torch Plan Key High-tech Enterprise” and “National Recognition” recognized by the Ministry of Science and Technology and other ministries. Enterprise Technology Center."
Long-term technology accumulation has made Yutong a new energy bus leader in China and around the world. Especially in the product reserve of pure electric bus, Yutong has completed the 6~18m full range of pure electric bus product layout, covering various market segments such as bus, tourism, group and special vehicles, in battery, motor and electricity. In terms of control, it has many core technologies, among which, vehicle energy-saving and control technology, high-voltage isolated power conversion technology, and high-density electric drive control technology are at the international advanced level.
Under the strong support of national policies, Yutong is a keen prophet and actively undertakes the promotion and landing of scientific research projects in the country and many provinces and cities. During the “Twelfth Five-Year Plan” period, Yutong undertook 22 national and provincial new energy research projects, of which 13 were national-level projects. In 2014, Yutong undertook the task of “National Electric Bus Electronic Control and Safety Engineering Technology Research Center”. The center is located in the transformation and scientific research and development of scientific and technological achievements and the “safety technology” of the core technology of electric bus. It has the ability to develop and test the electronic control and safety technology of five major systems, such as electric bus power system, vehicle energy, motor drive, vehicle control and electric accessories, and realize the engineering and industrialization of electric bus series products.
Yutong has also established the most professional new energy vehicle remote monitoring system in China. Combined with CAN network technology and information transmission technology, it provides remote wireless, real-time monitoring and background backup data for vehicle status, power battery, power system and electric auxiliary system. Automated fault diagnosis, operational maintenance and automation and safety monitoring.
In January 2016, at the National Science and Technology Awards Conference, Yutong’s “Key Technology R&D and Industrialization of New Energy Bus” project won the second prize of the National Science and Technology Progress Award. The project broke through “the key components depend on imports, and the integration is low. The cost is high; the short life of the power battery system is poor, the environmental adaptability is poor; the energy utilization rate of the whole vehicle is low, and the driving range is short, which is the three major technical problems that restrict the development of China's energy saving and new energy buses.
In 2016, Yutong's new energy bus sales reached 26,856 units, an increase of more than 30% year-on-year, and sales continued to rank first in the world.
Strength As the only company that provides pure electric bus service for two consecutive years, Yutong's corporate strength and product strength have been highly recognized by the user market. In 2016, the E10 debuted as a new energy bus in the service vehicles of the two conferences, realizing the “zero breakthrough” of the two-party new energy vehicles, and the same as the “zero fault” record of the two-way vehicles maintained by Yutong Bus in the past 12 years. Excellent performance, it is precisely because of this, this year Yutong's E10 lived up to the expectations of the re-election, after a rigorous and meticulous inspection, in the most perfect state to go to the two sessions, as the important mission of the two club service vehicles.
It is worth mentioning that the E10 is a 10-meter pure electric bus that Yutong has carefully developed and put on the market. It uses Yutong's unique core control technology, which is highly integrated and modular, reducing the number of parts by 57% and integrating more. High, safer and more reliable; battery, motor, electronic control and other key components have IP67 protection level, wading depth is better than traditional power bus, leading in the industry; battery has been overcharged, overdischarged, high temperature, short circuit, extruded Various destructive tests, such as dropping, soaking, puncture, etc., meet various extreme working conditions, and are safe and reliable.
In fact, in February of 2017 before the two sessions, Yutong’s new energy bus products were released under the theme of “Smart Leading·New Upgrade”. The newly upgraded R&S technology firstly raised the technical requirements for the safety of the national electric bus. The "Yutong 3S Safety Technology Requirements" has achieved comprehensive upgrades on the basis of fire prevention, waterproofing and anti-shock, covering monitoring safety, wading safety and collision safety upgrade, etc., which provides an important guarantee for the operation safety of new energy buses. In addition, combined with the new technical requirements of the subsidy new policy on battery energy density, energy consumption per unit load (Ekg), total battery system quality, vehicle maintenance quality ratio, driving range, fuel economy, etc. The core control technology has been comprehensively upgraded, and at the same time, it has significantly improved the adaptability of the products in the plateau, alpine and mountainous environments.
The continuous service of the two sessions represents that Yutong New Energy Bus has gained a high degree of recognition from the user market and the industry. This kind of affirmation stems from Yutong's persistence in quality and innovation.
But Yutong is not only satisfied with this. Now Yutong is working on the in-depth study of the interconnection of new energy buses. It uses the multi-layer interaction of “smart + network + electric” to realize the intelligent information exchange and sharing of electric buses, which in turn has complex environment perception, intelligent decision-making and Coordinated control for a more distant future.
