With the slow development of new energy vehicles in the private sector, the development of hybrid and pure electric buses has been in full swing in recent years, but the scope of operation is limited to the cities. This year, this situation has changed a lot. More and more hybrid and pure electric passenger cars have begun to break through urban restrictions and enter intercity lines and long-distance passenger lines.
New Energy Bus Targets Long Distance Lines
According to reports, at the Beijing International Road Transport, Urban Public Transport Vehicles and Components Exhibition held in late May of this year, Xiamen Jinlv exhibited the XML6122JHEV85C hybrid new urban express train. This car is between the ordinary city bus and coach. It is designed for urban, intercity and suburban routes.
The Golden Brig New City Express is a 12-meter coach. The body is 3.4 meters high. The low-floor double door design can accommodate up to 52 people. The power part adopts a mature and reliable Golden Travel hybrid system and has an automatic shift function. Among them, Golden Brig's unique asynchronous motor power generation system and dual electronic intelligent temperature-controlled cooling system ensure that the engine and drive motor are in the most ideal, stable, and efficient working state at all times, and the operation is more intelligent and the fuel-saving effect is more obvious. The car can also achieve idling during normal electric driving, which in turn enables more intelligent and optimized power generation control. With the closed-loop full load-bearing structure and the industry's first full vehicle cathodic electrophoresis technology, the economical and dynamic nature of the entire vehicle can be achieved. At the same time, the launch of the XML6122JHEV85C model actively responded to the country's call for energy-saving and emission-reduction and vigorously developed its own research and development of new energy vehicles, and enjoyed the national support subsidy policy.
According to Jiang Xin, general manager of Chongqing Hengtong bus sales company, Hengtong bus will also develop gas-electric hybrid buses for intercity lines.
On May 8, four pure electric buses equipped with lithium-ion batteries were driven out of Chaoyang City, Liaoning Province. One hour later, they entered the Jinzhou World Expo Park, marking the world’s first long-distance operation line for new energy pure electric high-speed buses. Officially open to traffic. This line is the "Chaoyang-Jinzhou Expo" tourism line. The bus used in the route is Ankai HFF6127K46EV-5 pure electric bus, which can completely replace the fuel and achieve zero emissions. According to reports, the four Ankai pure electric buses have completed a 10,000-kilometer trial run in the cold winter environment and have experienced the cold temperatures of minus 24 degrees Celsius in the north-eastern winter. 
“It is not new to launch hybrid buses on longer-distance lines. However, a number of companies have also launched hybrid buses and pure electric buses on longer lines, demonstrating the progress of the new energy bus industry.†A bus company official told reporters.
In 2010, Yutong Bus put 10 parallel-type hybrid buses on the Cheng (State) Kaifeng (Front) intercity line. Yutong bus related sources told reporters that the product uses imported hybrid power systems, the use of lithium batteries, from the perspective of the operation of these vehicles, the fuel economy is 5% to 10%, is not ideal, reliability is acceptable, normal operation . “It can be seen from this that the imported parallel system is not suitable for the typical urban working conditions in China. To solve this problem, Yutong has independently developed a hybrid system,†he said.
Nowadays, the new hybrid bus developed by Yutong Bus adopts a hybrid system, cancels the transmission, adopts stepless variable speed motor and intelligent start-stop technology, and the average pollutant emission is 69.5 times lower than that of traditional passenger cars. %, carbon monoxide reduced by 15.2%, hydrocarbons decreased by 65.1%, carbon dioxide decreased by 42%, PM decreased by 90%, fuel consumption was reduced by 40%, and has significant emission reduction effect, which can effectively improve the quality of urban atmospheric environment.
The hybrid buses developed by Xiamen Golden Brigade have won awards in the actual energy conservation competition for new energy buses in recent years and have been put into operation in Beijing, Hangzhou, Xiamen and other cities, including intercity links and fast lines in some cities. Good results, significant fuel economy.
The person in charge of the Xiamen Golden Brigade told reporters that the operating conditions of the intercity line and the city bus route are very close, and the advantages of the hybrid system can be fully utilized to fully consider the work of the hybrid system and the engine operating mode in the design of the power transmission system. Operating characteristics to improve the vehicle's fuel economy. Jinlv New City Express is equipped with a new generation GHS-IV hybrid mixing system independently developed by Golden Brigade with automatic transmission function. The electric power ratio of the vehicle exceeds 50%, the fuel saving rate exceeds 40%, and the maximum climbing degree exceeds 20 degrees. The speed can reach 100km/h; and the troubles of frequent trampling and loosening of the daily driving are avoided, which greatly reduces the work intensity of the driver. It is understood that the car will be listed in July.
From the above data, it can be seen that the technology of hybrid buses developed by domestic passenger car companies has accumulated over the past few years and has been significantly improved. Moreover, the transition of hybrid buses from the city to the suburbs reflects the confidence in the reliability of vehicles.
Pure electric buses operate on long-distance routes and are even more eye-catching. According to reports, the pure electric bus that is put on the “Chaoyang-Jinzhou Expo†tourism line can run continuously for 280-320 kilometers after full power, and the speed is 100-110 kilometers per hour, which greatly exceeds the operating range of the original pure electric vehicle.
An Kai, chief engineer of Ankai Bus Company, told reporters that after several years of technical accumulation, the energy density of the Ankai pure electric bus battery pack has increased by 15% to 20%, and the continuous driving range of the vehicle has increased by 20% to 30%. This provides technical support for pure electric buses from the city to long-distance lines.
Local government’s passion for promotion
Due to the significant energy-saving and emission-reduction effects, many cities are planning to put more hybrid buses and pure electric buses on the routes for longer distances.
Earlier this year, the Zhengzhou Municipal Government of Henan Province issued the "Notice of the New Energy Vehicle Demonstration and Industry Development Action Plan (2013-2015)" in Zhengzhou City. It plans to open Zhengzhou-Kaifeng, Zhengzhou-Xuchang pure electric intercity bus operations by the end of 2013. Lines, put into the exchange of pure electric bus 50. In 2015, Zhengzhou-Jiaozuo and Zhengzhou-Luoyang pure-electric intercity bus lines were opened, and pure electric city bus lines from Zhengzhou to all counties (cities) were opened, and 200 change-over electric-only buses were put into operation. By 2015, it will strive to achieve a total of 400 vehicles for the city's electric-transplantation electric-electric intercity (city) bus, which will basically form a pure electric intercity bus operation network centered on Zhengzhou City and covering the Central Plains City Group.
It is understood that at present, companies intending to try to put pure electric buses on long-distance passenger lines are not rare. Shandong Qingdao Jiaotong Group intends to place pure electric buses on the Qingdao-Jinan and Qingdao-Rizhao lines to reflect the importance of energy conservation and emission reduction.
Yutong bus related sources told reporters that the new energy vehicles as the development direction of the international automotive industry, is also a strategic emerging industry that the government supports and develops. Accelerating the development and development of energy-saving and new energy vehicles is not only effective in alleviating energy and environmental pressures, but also driving automobiles. The urgent task of industrial sustainable development is also a strategic measure to speed up the transformation and upgrading of the automobile industry, cultivate new economic growth points and international competitive advantages. With the continuous maturation of energy-saving and new energy vehicle technologies, and with further support from government policies, it is believed that energy-saving and new energy vehicles, especially energy-saving and new energy passenger vehicles, will continue to grow rapidly in the future.
With the increasingly close connection between the cities of the Central Plains agglomeration and the concentration of travel between cities, Yutong has specially developed the ZK6141BEV1 intercity highway passenger car for the medium and short-distance intercity passenger transport market. This vehicle is currently the only one in the country. A 13.7-meter pure electric road passenger car has fast battery replacement. Each time it takes 8 to 10 minutes for power exchange, it has a long driving range and can continue to operate for more than 500km per day to meet customers' operational needs. In addition, Yutong also undertook the R&D project of the national 863 plug-in hybrid electric bus. The comprehensive fuel-saving rate of the plug-in hybrid bus developed by the company exceeds 50%, and its product adaptability is very wide. It is Yutong's key promotion product.
