The number of hybrid buses in China has reached 17,000.

Wang Binggang, head of the supervision and advisory expert group of the National 863 Program “Energy-saving and New Energy Vehicles” major project recently expressed at the 2013 China International Forum on Promoting New Energy Vehicle Marketization: “At present, hybrid buses are the development of new energy automotive industry. One of the best performing types in China. By 2015, in the absence of state financial subsidy, hybrid buses will likely have market competitiveness.” This is a demonstration project for the “10 cities, 1,000 vehicles” energy-saving and new energy vehicles. The promotion of hybrid buses has given a high degree of evaluation.

In Wang Bing-gang's opinion, from the perspective of the promotion of domestic hybrid buses, hybrid buses have not only lost opportunities for development in the world, but have quickly approached the edge of industrialization.

Mixed bus technology is satisfying

Wang Binggang emphasized at the forum that hybrid buses are the best type of development for all types of new energy vehicles. "As of the end of 2012, the total number of demonstration vehicles of various types in the country reached more than 27,000, of which, the number of hybrid buses reached 1,121.5, which accounted for about half of all model vehicles." The number of buses in the non-demonstration cities is 5,000. This task has already been completed.” Therefore, the number of 5,000 vehicles and the promotion of the previous three years, the current number of domestic hybrid buses has reached 17,000. Vehicle.

In addition to the satisfactory number of hybrid buses being promoted, Wang Binggang believes that the gradual maturation of hybrid bus technology is even more gratifying. "When testing hybrid buses, the combined data is satisfying."

It is understood that in 2012, the national 863 plan expert team conducted various tests for 13 types of 12-meter hybrid buses in Kunming. Among them, in the fuel consumption test of urban conditions, the fuel consumption per 100 km was at least 24.55 liters. It is 31.6 liters (not under air condition). If the traditional 12-meter bus consumption is 36 litres/hundred kilometers, the fuel economy of the hybrid bus can reach 31.8%. Regarding the achievements of hybrid buses, Wang Binggang believes that there are indeed many people who have done a lot of work before they have achieved very good results. “The hybrid buses like Yutong, Wuzhoulong, and Jinlong are all doing very well, and the corresponding sales volume is also great.”

Mixed technology future competitiveness

At present, the technical systems adopted in China's hybrid buses are classified into three types: shallow mix, medium mix, and deep mix. In Wang Bing-gang's view, the hybrid system technology in hybrid buses tends to be stable. The best system operating conditions in a city with 100 kilometers of fuel consumption is about 24 liters (12 meters of passenger cars), and its future competitiveness is very large.

To this end, Wang Binggang called for China's relevant bus companies to continue investing in research and development of Chinese-Mixed technology and to reduce their costs. “If you make an estimate, if the cost of fuel vehicles does not increase by more than 150,000 yuan to 200,000 yuan, then in 2015, in the absence of state financial subsidies, the hybrid buses may already have market competitiveness. This goal, many The company believes it can be achieved in the next 3 years."

However, because deep mixing technology has the advantage of higher fuel economy, Wang Binggang therefore stressed that bus companies need to patiently continue to invest. He thinks: "The hardest part of a hybrid car is a deep-mixed car. This piece of technology has to make good progress. It really needs to be in the market for two years or more."

“Accelerate the realization of the industrialization of deep hybrid passenger cars and further achieve the goal of fuel consumption of less than 20 liters/100 km.” According to Wang Binggang, if this goal is achieved, hybrid buses can enter the marketization stage, and the new energy automobile industry can also The "import period" entered the "fast development period." Wang Binggang emphasized that companies that do deep-mixing technology must have confidence and determination. He believes that domestic companies can do a good deep-mixing technology as well.
