China's Hybrid Electric Vehicles



It is predicted that by 2013 China will produce only 14,000 China's hybrid electric vehicles per year. The biggest drag on Chinese hybrids is cost. There are 8 hybrid models launched in China in 2008, and by 2013 there will be 10 hybrid models.

1. China’s Hybrid Vehicles

The EQ7200 motor drive system of China's hybrid vehicles Dongfeng Motor Hybrid Electric Car is the most difficult subject in the "10th Five-Year Plan" and "863 Plan" special motor drive common technology. The torque density of the permanent magnet motor is comparable to that of the Toyota Prius hybrid motor. The research group has successfully developed a permanent magnet reluctance motor with a high peak torque of 180N•m and a 4 times weaker field and its drive, and has completed a 15,000-kilometer formal certification experiment.

In addition, Jiexun Hybrid is a pure China's hybrid electric vehicles developed by Changan Automobile Group. From the entire China's hybrid electric vehicles to the hybrid system, it is independently developed by Changan Group and has complete independent intellectual property rights. The level of power components such as hydrogen power batteries is in a leading position in China's hybrid vehicles. The China's hybrid electric vehicles can maximize the energy saving and environmental protection advantages of the hybrid system on the premise of ensuring power.

Beiqi Foton Hybrid Vehicles have been commercialized in Guangzhou, thus becoming one of the earliest enterprises in China to realize commercialized production of new energy vehicles. In 2004, Foton Motor began to develop hybrid buses. Foton's research and development of hybrid vehicles is based on independent development, but at the same time, it adopts the research and development method of introduction, digestion, absorption and innovation, and carries out technical cooperation with Eaton Corporation of the United States to jointly develop hybrid power systems. Taking city buses as the breakthrough point in research and development, we will focus on the development of 11.4m large city buses and 12m hybrid buses. The joint development has significantly accelerated the research and development speed of Foton's hybrid electric bus, and the industrialization process has also been greatly shortened. In July 2005, the whole China's hybrid electric vehicles design was completed. In December 2005, two prototypes were successfully trial-manufactured. In October 2006, the reliability test of nearly 70,000km was completed. On January 11, 2008, Guangzhou First Bus Company purchased 30 Foton hybrid buses for commercial operation in the urban area of ​​Guangzhou, taking the first step in the industrialization of hybrid buses in China. As of June 20, 2008, the cumulative mileage of these China's hybrid electric vehicles was 1.1 million km, the longest mileage per vehicle exceeded 50,000 km, the average attendance rate was 97.2%, and no major failures occurred; the average fuel consumption per 100 kilometers was 30.5L, and The minimum fuel consumption per 100 kilometers is 27.3L, and the average fuel consumption is more than 25% lower than that of traditional models; nitrogen oxides are reduced by about 27%, and absorbable particulate matter is reduced by about 19%, which is close to the national N level. Reliability, fuel economy are outstanding, and emission reduction effect is remarkable. Allegedly, it is now 400,000 to 500,000 yuan to buy a traditional air-conditioned bus, and the price of a hybrid vehicle in China is 850,000 to 900,000 yuan. The difference between the two is about 400,000 yuan. However, the use of hybrid electric buses can save about 89,100 yuan in fuel costs each year. At present, Foton hybrid electric buses use Japanese batteries with an 8-year warranty period, which saves a total of about 700,000 yuan during its service life. Foton is also developing a plug-in hybrid technology, which uses "fuel-electric-electric-electric four-hybrid". The oil is the traditional fuel engine, and the three "electric" refers to the battery, the capacitor, and the power supply. The project is applying for the national "863" project. At present, Foton Motor has made a systematic plan for the future development of new energy vehicles, and established a special new energy vehicle research center. In addition to the passenger cars that have made remarkable achievements, the company will launch new energy models such as trucks, MPVs, and small multi-purpose vehicles in the near future, striving to stand on the same starting line with international companies in new energy technology.

As the city with the earliest start of electric vehicle demonstration operation, the largest scale, the widest operating area and the highest degree of industrialization in China, Wuhan has basically formed an electric vehicle industry chain integrating electric vehicle R&D, industrialization, and demonstration operation. Wuhan's electric vehicle demonstration operation vehicle scale and demonstration operation mileage are in a leading position in China and have formed an international influence. Wuhan's electric vehicle business has shifted from research and development to the stage of industrialization where production and commercial promotion are the main focus. The industry chain has been extended around the industrialization of electric vehicles. It has basically formed three major businesses: research and development, demonstration operations and manufacturing. The core industrialization strategic layout has embarked on the fast lane of development. In the first five years of 2009, Wuhan built a total of 28 charging stations for electric vehicles. As of September 2008, the total operating mileage of 319 China's hybrid electric vehicles exceeded 16 million km, transporting more than 30 million passengers, reducing CO2 emissions by 3,100 tons, and saving 11 million liters of fuel. Among them, 50 Dongfeng hybrid buses have run 4.5 million kilometers in total, carrying 10 million passengers. 269 minibuses have operated 11 million kilometers and carried nearly 20 million passengers. Wuhan has become the largest hybrid vehicle operating scale and mileage in China. The longest and most passenger-carrying city.After the pure electric vehicle developed by Zhengzhou Nissan was approved for trial operation in Zhengzhou, Xinxiang, and Luoyang, Yutong did not want to lag behind, and in 2009, it sold gasoline-electric China's hybrid electric vehicles in batches. As of March 2009, Yutong has produced 7 prototypes of hybrid electric vehicles, which have been put into trial operation in Beijing, Guangzhou and Zhengzhou respectively, and Yutong has become the winning bidder for the Luoyang Electric Bus Demonstration Line Project. Of the seven gasoline-electric hybrid prototypes that Ningtong has produced, only one is 13.7m long, and the rest are 12m passenger cars. Recently, Yutong intends to produce an 18m-long gasoline-electric hybrid prototype, which should be the first new energy bus in China. In terms of production cost, a 12m hybrid car costs more than 400,000 yuan more than an ordinary car. The price of gasoline-electric hybrid buses is higher because they use a control system worth more than 400,000 yuan. In this system, lithium-ion batteries alone account for more than 200,000 yuan. According to reports, the hybrid device on the China's hybrid electric vehicles are mainly composed of lithium batteries, hybrid motors and wires. Among them, the state of the hybrid motor can be "adjusted" by itself in different driving states. For example, when accelerating, the hybrid motor will act as an electric motor to convert the electrical energy in the lithium battery into kinetic energy to cooperate with diesel for acceleration of the bus; when decelerating, the hybrid motor will act as a generator to convert kinetic energy into electrical energy and store it in the lithium battery. The lithium battery can be charged and used while driving, eliminating the trouble of charging the battery every day. Due to the simultaneous use of diesel and electricity, the amount of diesel used is correspondingly reduced, and the amount of exhaust gas is also reduced. When the bus starts, it is not like a thick black smoke floating from the tail of an ordinary passenger car, only a faint and almost invisible smoke. Under the theoretical and best operating conditions, the hybrid buses currently produced by Ningtong can save 17%~19% of fuel compared with ordinary buses with automatic transmission. Up to 25%. Generally, the operation cycle of a passenger car is 8 years, and it travels about 600,000 km. The new energy vehicle can save 60,000 liters of fuel during the operation cycle. If calculated according to the diesel price of 6 yuan/L, the fuel cost can be saved by 360,000 yuan.
