Zhengzhou Yutong Bus : Yutong launches integrated solution program of electric buses

The launch ceremony of "Yutong integrated solution program of pure electric buses" was grandly held in Zhengzhou on November 28, 2014. As a leading company of new energy buses, Yutong launched the first "integrated solution program of pure electric buses" in China, proposing the systematic operation way in terms of products, ancillary facilities, services and financing to promote the commercialization of new energy buses. Currently, the program has been successfully applied in Tianjin, Nanjing, Zhengzhou and other cities.

"Hard standards" set quality benchmark of electric buses

As the core of the solution program, the electric buses with high quality are by all means the top priority. However, there are electric buses with good and bad quality in the market, and the issues like battery quality and charging ways are always the difficult problems in the industry. As the leader of the industry, Yutong, with its own leading technical strength and sustained investment in R&D area, launched E-series electric bus products. The buses have finished the improvement and demonstration run phases and are available for being launched in the market. 

Li Gaopeng, chief engineer of the National Research Center on Electronic Control & Safety Engineering Technology of Electric Buses, said that the strict performance parameter indexes of Yutong E-series electric buses in terms of product safety, battery performance, electronic control technology, reliability of whole vehicle and so on have set the first ever "Hard standards" for China's bus industry.

Firstly, Yutong's unique all-in-one system safety technology of whole vehicles can ensure the safety of products. It is a system supported by a number of indexes. At the beginning of the engineering, it already took into account the structural safety, high voltage safety, functional safety and so on. It also adopted three-level verification system, namely components, powertrain systems and whole vehicles, greatly improving the reliability and durability of vehicles.

The batteries used for Yutong E-series electric buses have gone through a number of destructive tests, like high temperature, crush, puncture, short circuit, soak and overshoot, to guarantee the operational safety. The adoption of structural safety design makes the rollover test angle reach 45 degrees, far beyond 28 degrees stipulated by the national standards. The protection class of key components like motors and electronic control system has reached IP67, the highest level of wiring in the electronic industry.

Regarding to the performance of whole vehicles, Yutong's electric buses have fully met the requirements of conventional roads. Taking E7 as an example, it takes only 8.22 seconds to bring the vehicle speed from 0km/h to 50km/h, and the vehicle can also easily pass the rampway with 20% gradient.

We can say that the multiple "hard standards" not only ensure the high quality of Yutong electric bus products, but also set a quality benchmark of electric buses for the industry.

"Soft power" guarantees the easy operation of electric buses

In respect of ancillary facilities, Yutong creatively proposed three sets of programs for the construction of charging stations based on the four big systems of the construction of charging stations. Customers can choose from them based their actual situations and Yutong can tailor-make the proposal based on customers' specific needs, provide whole-process assistance and even have it constructed for customers, thus effectively addressing customers' difficulties on ancillary facilities. Meanwhile, Yutong also developed the remote monitoring and diagnostic system, enabling users to conduct automatic management of battery charging while staying indoors.   

Yutong's new energy buses have covered 20 exemplary cities and city agglomerations and also 38 non- exemplary cities. From September 2013 to now, Yutong has promoted over 5,800 new energy buses and achieved good effect in Tianjin, Nanjing, Zhengzhou and many other cities.

Industry experts said that China's electric buses have begun to develop and the integrated solution program of electric buses launched by Yutong is expected to speed up the development of electric buses. During this process, Yutong, as the leader of China's new energy bus industry, actively explored the development path of electric buses, firstly launched the solution program that promoted the development of the industry and gave full play to its leading role in the industry.
