Plug-in hybrid bus trend

Under the dual pressure of energy conservation and emission reduction, energy-saving and new energy vehicles will undoubtedly become the development direction of the international automotive industry. The world’s major auto-producing countries and large-scale automobile companies have stepped up investment in R&D and application of energy-saving and new energy vehicles, while vigorously developing and promoting the application of automotive energy-saving technologies.

At present, the technical path of new energy vehicles mainly includes plug-in hybrid and pure electric. The general view in the industry is that pure electric vehicles and fuel cell vehicles are long-term strategic goals. The best choice during the transition period is hybrid vehicles. However, pure electric buses use batteries as driving energy, replacing the engine mode, achieving zero emissions and greatly reducing noise, but at this stage, charging network construction is imperfect; ordinary hybrid buses save fuel/gas, but the battery Very small capacity, only supply/recover energy at start/stop, acceleration/deceleration, can't use long-distance driving in pure power mode, no external charging, and plug-in hybrid power can be charged externally, with pure electric drive available With a battery life of about 30 kilometers, after the power is exhausted, the fuel can be used to drive the engine, which can ensure that the operation is not stopped and the train does not stop. It is the key point for the development of China's energy-saving and new energy automotive industry, and is also the ideal choice for the pure electric vehicle.

National policies strongly support plug-in hybrid buses On June 28, 2012, the State Council issued the "Energy-saving and new-energy automotive industry development plan (2012-2020)", which established "the development of pure energy as a new energy vehicle and automotive The main strategic orientation of industrial transformation, currently focusing on promoting the industrialization of pure electric vehicles and plug-in hybrid vehicles, popularizing non-plug-in hybrid vehicles, energy-saving internal combustion engine vehicles, and upgrading the overall technological level of the automotive industry in China”, and “The cumulative production and sales volume of pure electric vehicles and plug-in hybrid vehicles will reach 500,000 units by 2015; by 2020, the production capacity of pure electric vehicles and plug-in hybrid vehicles will reach 2 million, and the cumulative production and sales volume will exceed 500. The main goal of 10,000 cars. Plug-in hybrid buses have become one of the major types of vehicles supported by national policies.

On September 13, 2013, the Development and Reform Commission of the Ministry of Industry and Information Technology of the Ministry of Finance and Technology jointly issued the "Notice on Continuing the Promotion and Application of New Energy Vehicles" in order to promote energy saving and emission reduction through the development of new energy automobile industry and promote Air pollution control. The new round of subsidy policies include: pilot cities as the core, setting up pilot areas, expanding the scope of radiation, and accelerating the promotion of regional electric vehicles; improving the original financial fund subsidies and accelerating the implementation of capital subsidies; hybrid buses will be promoted throughout the country; The construction of charging stations is financed. After subsidizing new energy vehicles to the company, it will directly improve the performance of the company and thus increase the market valuation of new energy vehicles.

The development of plug-in hybrid technology in Europe, the United States and Japan, in addition to the strong support of national policies, plug-in hybrid power has also received extensive attention from international new energy giants.

In 1997, Toyota launched the world's first mass-produced hybrid vehicle Prius, marking the official entry of new energy vehicles into the industrialization stage; starting in 2007, due to energy shortages and global energy-saving emission reduction calls for the development of new energy The car has become the consensus of the global automotive community. Although the automobile giants of the United States, Japan, Germany, and France all agree with this path, the initial development directions are different. The Japanese department focuses on the development of hybrid vehicles, while the US Department directly develops fuel cell vehicles. At present, Japan's hybrid power has developed into the second generation, and its power and fuel economy are even better; on April 1, 2009, Japan began to implement a "green tax system", which eliminates consumers from buying pure electric vehicles and hybrid cars. Multiple taxes. Japan plans to develop at least 38 hybrid vehicles and 17 pure electric vehicles by 2020; the United States invested 2.4 billion U.S. dollars in August 2009 to support the development and industrialization of plug-in hybrid vehicles, of which 2 billion U.S. dollars will be used to support Advanced power battery research and development and industrialization. In addition, the U.S. government announced the implementation of the Green New Deal, and plans to popularize 1 million plug-in hybrid electric vehicles by 2015. Consumers can purchase new energy vehicles while reducing taxes while also reducing the parking fees in public places; the German government in 2008 In November of this year, it proposed to popularize 1 million plug-in hybrid vehicles and pure electric vehicles in the next 10 years; Germany has also started a project to invest 420 million euros in the development of lithium batteries for vehicles from this year.

Hengtong Electric Bus: Establishing the First Brand of China's Fast-Recharging Passenger Cars However, the plug-in hybrid buses on the market currently have problems such as high battery load, long charging time, and low number of cycles of battery charging and discharging, resulting in plug-in hybrid vehicles. Passenger cars have not been better promoted and applied. To this end, Hengtong Electric Bus, which is committed to building the "China's first brand of fast charging passenger cars," actively explores a technology line more suitable for the actual needs of new energy bus development and more capable of deducing commercial operations. Power, and relying on the company's core advantages in super multi-cell composite lithium-ion battery and 10-minute fast charging technology, has opened up a new era of commercialization of quick-charge plug-in hybrid electric buses.

It is understood that Hengtong Electric Bus is the only passenger car manufacturer in China's passenger car industry with the "rapid charging" as the core strategy. Since 2007, the company has invested a great deal of human and financial resources and established the “Gas and New Energy Bus Research Institute”.
