Characteristics and Development of Some Kinds of New Energy VehiclesAbstractNow the global automotive industry is facing the challenge of energy and environment,and developing new energy vehicles becomes many global automotive groups’s same plan.But not all of various types of new energy vehicles which have their own advantages and disadvantages can become the most promising future vehicles.I will introduce features and development of Pure Electric Vehicles 、Hybrid Electric Vehicle (HEV)、Fuel Cell Electric Vehicles (FCEV)、Natural Gas Vehicles、Hydrogen Engine Vehicles and DME Vehicles Etc. At last we will know which kind of the new energy vehicles will become mainstream in the future of the car by comparing.Key Word: New Energy Vehicles Future cars HybridHybrid cars is hybrid electric vehicles which use more than one kind of energy provides power to drives the car . Currently hybrid cars is the combination of traditional fossil fuels engin and electric motor. The most prominent advantage of hybrid cars is its fuel economy. The maximum power of the engin can determine by the average power ,so that the engin can work in less pollution and lower fuel consumption condition. That makes hybrid cars save 30%~50% fule compare with traditional cars,and significantly reducing emissions at the same time.Energy recovering from braking become easy too.But the problem of hybrid car is it’s high price and basicly no fuel saving at long distance、high speed driving.At present, China's hybrid vehicle technology development fast, some models have been in the period of practical .Take the Roewe 750 of Shanghai Automotive Group for example ,it has already on sale.In the world wild,Toyota Prius hybrid car first introduced in Japan in 1997,and the other major automobile companies havelaunched their own hybrid products, such as the Honda Insight, GM Saturn VUE, Ford Escape and so on.With technical progress and expansion of production scale,the cost has dropped significantly.Pure electric vehicles is driven by electric motor, which is powered by car-carry battery,and meet the requirements of traffic safety regulations.Pure electric vehicle using a rechargeable battery , and the basic structure is not complicated.Electric generators and car batteries are one of the key components, among which the most critical is battery.Pure electric vehicles is not a new car, the electric car was born more than 100 years. At that time the electric car battery lifespan is short, the mileage is not high also. Then the electric car is relaced by the increasingly technology mature internal combustion engine car. But in the 1970 s, due to the stimulation of oil crisis, all countries in the world began to look for other energy to replace oil. The electric car is back in the line of sight of people. And in recent years besides had the problems of energy, environmental problem has become a social focus on major issues. Againincreased focus on electric cars. Now the difficulty of promote puer electric car comes from the power storage technologies.Currently,energy storage in per unit weight of the battery is not enough for long -term using, the charge mileage is not ideal. On the other hand,The high-performance battery lifespan is short.Resulting in not froming economy scale, cost of pure electric vehicle is too high to commercial operation.Nevertheless, pure electric vehicles are promoted in the U.S., Europe, Japan in small-scale,and mainly use in government vehicle ,city bus Etc. The forerunner of China's electric car company BYD launched E6, and also exported electric bus to Europe .Fuel cell electric vehicle use a fuel cell as electric source to supply electric motor, and the chemical energy of fuel is directly changed into electrical energy by the cell.The energy conversion efficiency of the fuel cell is 2 to 3 times higher than internal combustion engines, and fuel cells do not produce harmful chemical reaction products and make lower noise.In recent years, although the development of fuel cell vehicles technology has made significant progress in the world wild , but there are still some technical challenges, such as the integration of fuel cells,vehicle integration, industrialization and commercialization. It is worth mentioning that we are at the same level with developed countries in the field of fuel cell electric vehicle researching.Hydrogen engine vehicle power by the engin which is transform from the existing automobile internal combustion engine.In addition to the hydrogen engine car has the same advantages of less pollution, lower emissions, but also has other special advantages, such as lower requirements for hydrogen, high combustion performance, engine technology is mature and so on.But now hydrogen engine car facing with problems of preparation and storage of liquid hydrogen .Ability to effectively solve these two problems in short time will determine the prospects for the development of hydrogen engine vehicles.Natural gas vehicles to use natural gas as fuel .According to the chemical composition and morphology of natural gas ,it can be classified as three kinds of it ,like Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas . Because natural gas vehicles using natural gas as fuel, so it has some feature like low pollution, low cost and high security.But natural gas vehicles have lower power performance, not easy to carry compared with normal vehicle. And once put into Large-scale using, we must build the appropriate station and pipeline.It also relates to design urban planning, funding and environmental safety, and many other factors, causing the high cost of using this kind of vehicle.China is rich in natural gas resources, and natural gas vehicle technology developed rapidly in these years . For example, some taxi Changsha use Compressed Natural Gas engin.In addition to the above new energy vehicles, as well as,there is also a kind of vehicle using organic substance, such as alcohol, ether as fuel to power the car.Ethanol fuel is ethanol automotive gasoline, ethanol vehicle technology is relatively mature, thetraditional internal combustion engine can modification to adapt to different ethanol gasoline fuel. The rapid development of ethanol cars happen in United States, Brazil and other countries thanks to the rich ethanol resources, while China is still in its initial stage.DME car use DME as fuel of compression-ignition engine. Generally using in two ways: Firstly, using the dimethyl ether as an ignition-promoting secondly dimethyl ether used as the direct combustion of liquid to get power.Dimethyl ether automobile technology in China has made important progress, such as Shanghai automotive group has successfully developed in dimethyl ether city bus, and began the trial runThanks to internal combustion engine technology is now very mature, hybrid cars is ease of using , sustainability, reliability is better than that of other new energy cars, but its still use gasoline, diesel oil as a source of energy, so the hybrid vehicle can't represent the future type of car. And because the power can be obtained from a variety of one-off energy,do not worry about energy draining, so pure electric vehicle has broad application prospects. At the same time, pure electric vehicles has no pollution, makes lower noise, is high efficiency. These advantages make this type of electric car research and application is becoming a hot spot of the car industry, and our country also take electric vehicles as the main orientation of auto industry strategic transformation. Fuel cell vehicles, with its efficient green cleaning and life advantage to get the attention of many countries to continuously invest devotion, therefore the fuel cell car will also be important form of the cars of the future. For other types of new energy vehicles, because of the limitations of fuel supplying, can't be used in the large scale all over the world. And this kind of alternative fuel in the engine power performance, corrosion, storage and transportation difficulties, such as obvious shortcomings. This kind of new energy vehicles may will be the future regional auto supplement type.Comparing the above list of various types of new energy vehicles, pure electric vehicles will be themainstream of future automobiles, fuel cell vehicles will act as an important component in the future , and a hybrid car is the transition models before exhausting of petrochemical resources, other types of cars are supplement adjust measures to local conditions. Pure electric vehicles is the most promising new energy vehicles, and is strongly supported by the state.Now some electric vehicles is used in the urban public transport, major activities.We look forward to the clean traffic early arrival of the era.References[1]邹政耀,王若平.新能源汽车技术.北京:国防工业书版社,2012[2]石川宪二.新能源汽车技术及未来.康云龙,余开江译.北京:科学出版社,2012[3]冯景毅.基于48V电压平台解读比亚迪绿混技术.汽车之家网,2013[4]黄正桥.陈斌波:电动汽车是未来汽车发展的方向.汽车之家网,2011[5]Sperling, Daniel.Two Billion Cars:Driving Toward :Oxford University Press,2009[6].Ranjan K.

That makes hybrid cars save 30%~50% fule pare with traditional cars,and significantly reducing emissions at the same time.Energy recovering from braking bee easy too.But the problem of hybrid car is it’s high price and basicly no fuel saving at long distance、high speed driving.At present, China's hybrid vehicle technology development fast, some models have been in the period of practical .Take the Roewe 750 of Shanghai Automotive Group for example ,it has already on sale.In the world wild,Toyota Prius hybrid car first introduced in Japan in 1997,and the other major automobile panies have launched their own hybrid products, such as the Honda Insight, GM Saturn VUE, Ford Escape and so on.With technical progress and expansion of production scale,the cost has dropped significantly.Pure electric vehicles is driven by electric motor, which is powered by car-carry battery,and meet the requirements of traffic safety regulations.Pure electric vehicle using a rechargeable battery , and the basic structure is not plicated.Electric generators and car batteries are one of the key ponents, among which the most critical is battery.Pure electric vehicles is not a new car, the electric car was born more than 100 years. At that time the electric car battery lifespan is short, the mileage is not high also. Then the electric car is relaced by the increasingly technology mature internal bustion engine car. But in the 1970 s, due to the stimulation of oil crisis, all countries in the world began to look for other energy to replace oil. The electric car is back in the line of sight of people. And in recent years besides had the problems of energy, environmental problem has bee a social focus on major issues. Again increased focus on electric cars. Now the difficulty of promote puer electric car es from the power storage technologies.Currently,energy storage in per unit weight of the battery is not enough for long -term using, the charge mileage is not ideal. On the other hand,The high-performance battery lifespan is short.Resulting in not froming economy scale, cost of pure electric vehicle is too high to mercial operation.Nevertheless, pure electric vehicles are promoted in the U.S., Europe, Japan in small-scale,and mainly use in government vehicle ,city bus Etc. The forerunner of China's electric car pany BYD launched E6, and also exported electric bus to Europe . Fuel cell electric vehicle use a fuel cell as electric source to supply electric motor, and the chemical energy of fuel is directly changed into electrical energy by the cell.The energy conversion efficiency of the fuel cell is 2 to 3 times higher than internal bustion engines, and fuel cells do not produce harmful chemical reaction products and make lower noise.In recent years, although the development of fuel cell vehicles technology has made significant progress in the world wild , but there are still some technical challenges, such as the integration of fuel cells,vehicle integration, industrialization and mercialization. It is worth mentioning that we are at the same level with developed countries in the field of fuel cell electric vehicle researching.Hydrogen engine vehicle power by the engin which is transform from the existing automobile internal bustion engine. In addition to the hydrogen engine car has the same advantages of less pollution, lower emissions, but also has otherspecial advantages, such as lower requirements for hydrogen, high bustion performance, engine technology is mature and so on.But now hydrogen engine car facing with problems of preparation and storage of liquid hydrogen .Ability to effectively solve these two problems in short time will determine the prospects for the development of hydrogen engine vehicles. Natural gas vehicles to use natural gas as fuel . According to the chemical position and morphology of natural gas ,it can be classified as three kinds of it ,like pressed Natural Gas (G), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas . Because natural gas vehicles using natural gas as fuel, so it has some feature like low pollution, low cost and high security.But natural gas vehicles have lower power performance, not easy to carry pared with normal vehicle. And once put into Large-scale using, we must build the appropriate station and pipeline.It also relates to design urban planning, funding and environmental safety, and many other factors, causing the high cost of using this kind of vehicle.China is rich in natural gas resources, and natural gas vehicle technology developed rapidly in these years . For example, some taxi Changsha use pressed Natural Gas engin.In addition to the above new energy vehicles, as well as,thereis also a kind of vehicle using organic substance, such as alcohol, ether as fuel to power the car.Ethanol fuel is ethanol automotive gasoline, ethanol vehicle technology is relatively mature, the traditional internal bustion engine can modification to adapt to different ethanol gasoline fuel. The rapid development of ethanol cars happen in United States, Brazil and other countries thanks to the rich ethanol resources, while China is still in its initial stage.DME car use DME as fuel of pression-ignition engine. Generally using in two ways: Firstly, using the dimethyl ether as an ignition-promoting secondly dimethyl ether used as the direct bustion of liquid to get power.Dimethyl ether automobile technology in China has made important progress, such as Shanghai automotive group has successfully developed in dimethyl ether city bus, and began the trial runThanks to internal bustion engine technology is now very mature, hybrid cars is ease of using , sustainability, reliability is better than that of other new energy cars, but its still use gasoline, diesel oil as a source of energy, so the hybrid vehicle can't represent the future type of car. And because the power can be obtained from a variety of one-off energy, do not worry aboutenergy draining, so pure electric vehicle has broad application prospects. At the same time, pure electric vehicles has no pollution, makes lower noise, is high efficiency. These advantages make this type of electric car research and application is being a hot spot of the car industry, and our country also take electric vehicles as the main orientation of auto industry strategic transformation. Fuel cell vehicles, with its efficient green cleaning and life advantage to get the attention of many countries to continuously invest devotion, therefore the fuel cell car will also be important form of the cars of the future. For other types of new energy vehicles, because of the limitations of fuel supplying, can't be used in the large scale all over the world. And this kind of alternative fuel in the engine power performance, corrosion, storage and transportation difficulties, such as obvious shortings. This kind of new energy vehicles may will be the future regional auto supplement type. paring the above list of various types of new energy vehicles, pure electric vehicles will be the mainstream of future automobiles, fuel cell vehicles will act as an important ponent in the future , and a hybrid car is the transition models before exhausting of petrochemical resources, other types of cars are supplement adjust measures to local conditions. Pure electricvehicles is the most promising new energy vehicles, and is strongly supported by the state.Now some electric vehicles is used in the urban public transport, major activities.We look forward to the clean traffic early arrival of the era.References[1]邹政耀,王假如平.新能源汽车技术.:国防工业书版社,2012[2]石川宪二.新能源汽车技术与未来.康云龙,余开江译.:科学,2012[3]冯景毅.基于48V电压平台解读比亚迪绿混技术.汽车之家网,2013[4]黄正桥.陈斌波:电动汽车是未来汽车开展的方向.汽车之家网,2011[5]Sperling, Daniel.Two Billion Cars:Driving Toward :Oxford University Press,2009[6].Ranjan K.

New energy vehiclesNew energy vehicles is a new automotive product type, because the development time is not long, the technology is still not mature, so has not yet formed a widely accepted concept, but it certainly is new energy automobile is compared to the traditional fuel vehicles, the new energy vehicles, according to the definition of the scope of the concept size, there are two types of narrow and broad statement.Generalized: used in gasoline and diesel oil as power source of the car.Special: a non conventional vehicle fuel as the advanced technology of powercontrol and drive, the formation of technology has advanced principle, new technology, new structure of automobile.New energy vehicles, including fuel cell cars, hybrid cars, hydrogen powered cars and solar car etc..Hybrid electric vehicle is a vehicle equipped with more than two source:battery, fuel cell, solar cell,Turbine locomotive.The current hybrid vehicles generally refers to the diesel generator, plus battery cars.Advantages:Vehicle starting and stopping, driven only by the battery, do not reach a certain speed,The engine will not work, therefore, can make the engine has been maintained in the best condition, good dynamic performance, very low emissions, and the source and power are the engine, gas can only. Its principle is simply the motor and engine the reasonable arrangement of power output machine.Disadvantages:There are two sets of power,Management control system plus two sets of dynamic,Complex structure,Difficult,The price is high and long distance speed is not fuel-efficient.Pure electric vehicle is composed entirely of rechargeable battery (such as lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries or lithium ion batteries provide power source for car).Pure electric vehicle motor fuel to replace machine, low noise, no pollution,and by the use of electrical energy single, electric control system of hybrid electric vehicle is greatly simplified compared. Reduces the cost, the price also can compensate the battery. Pure electric vehicle is mainly used for the airport, community, courts and other places.Disadvantages: only in certain range, the market is smaller. The main reason is because of various categories, the prevailing prices high, life is short, the size and weight of the large, long charging time, serious shortcomings.Fuel cell vehicles refers to the hydrogen, methanol as the fuel, the current through the chemical reaction, depending on the electric motor driven vehicles. The battery power is through the chemical reaction of hydrogen and oxygen, rather than through the combustion, directly into electrical energy.The chemical reaction process of fuel cell does not produce harmful products,therefore the fuel cell vehicle is a car without pollution, energy conversion efficiency of the fuel cell of high 2 ~ 3 times than the internal combustion engine, so the use of environmental protection and energy, fuel cell vehiclesand is an ideal vehicle.Household car is more and more, oil prices more and more expensive, every car company began to research and development of new energy vehicles.1.IntroductionChery since 2000 we have engaged in the research and development of the new energy vehicles, through more than ten years of independent innovation, the new energy vehicles business experienced three important stages of development; From 2001 to 2005, the company with the national 863 project for the carrier, joint top Chinese universities and research institutes, undertake and completed a number of national 863 electric vehicle research subject, the major projects in just3 years time, complete the ISG moderate hybrid and pure electric vehicles of the rational development model. From 2005 to 2008, approved by ministry of a "by national energy conservation and environmental protection automotive engineering technology research center", based on the basic completion of the new energy vehicles of the industrialization of the research and development, the establishment of a sound energy saving and new energy vehicle development system, the world first-class new energy test center, trial-produce center, in the electric car key components and core technology, the company has formed a set of key parts research, testing, application and industrialization of calibration ability, in the motor, motor drive system, DC/DC, advanced power battery, the battery management system, the vehicle controller, initially forming a batch production ability, have the new energy vehicles, the core technology of the calibration technology and experiment technology. New energy vehicles special vehicle accessories system, including: electric air conditioning, the electric steering (EPS), electric vacuum, electric heating, electronic brake system has been formed series products, with the bulk production ability. The first paragraph A5-BSG hybrid cars in 2008 listed in wuhu, batch, dalian city, as the taxi are greatly welcomed by customers, but also become henan, guangdong, xinjiang, shanxi, fujian, zhejiang and other private user's private cars. Moderate hybrid (ISG) car has entered the small batch production stage, which is DuoGe new energy vehicle demonstration pilot city, as the lease, the first choice of state-owned cars models. Miniature pureelectric vehicles and intermediate pure electric vehicles and miniature electric buses, pure electric taxies, pure electric bus industrialization development also has made a great progress. At the same time, we also pay more attention on high efficiency and energy saving the gasoline engine, the diesel engine technology, flexible fuel automobile technology, strong hybrid technology, fuel cell vehicle technology, comprehensive development, a number of technical are in the leading domestic level. Since 2009, the company launched a new comprehensive energy car large-scale industrialization and application, chery A5ISG, A5BSG, S11EV and S18EV has got a letter issued by the department work products in the country the announcement and saving energy and environmental protection products recommended directory; In January 2009, chery automobile company "energy conservation and environmental protection technology platform construction project" get "country" first prize progress prize in science and technology. In March 2010 the first batch of economical pure electric car delivery customers use and chery new energy vehicle technology Co., LTD. was set up, marked the new energy vehicle company opened a new chapter in the business2.Main discussion1. The advantages of new energy vehicles (strength) analysisThe state information center forecast, China's passenger car market growth situation will continue for at least a further 15 years, annual growth needs roughly equivalent to GDP growth in the 1.5 times or so. In 2009 a car into the family (middle-income families buy have ability). From the qualitative Angle, car market at least will also have 20 years of fast growth. If domestic GDP2020 years than in 2000, around 2020 words to quadruple our country will more than the United States, automobile demand will reach 20 million cars, as the world's largest car market.Since 1988, in fujian province, and become the largest of the special economic zone, the provincial capital of hainan province since the haikou city become haikou city won the top ten cities, and national environmental protection model city, national sanitary city, China excellent tourist city, national garden city, national historical and cultural city, a national civilization city advanced city, the work the comprehensive improvement of the urban environment, "China excellent city living environment prize" and so on the city reputation. Hainan consistent development of the island, environmental protection island is travel health island, new energy, cars are the city's another environmental and health. From the economic development prospects and haikou city car market development scale, in the city to see public transport, taxi, business, environmental sanitation and postal and other public service and other fields, new energy vehicles have a large market space.2.New energy vehicles disadvantages (weakness) analysis(1) the traffic congestion, chaos. Nearly five years motor vehicles and drivers haikou number to sustained growth, road traffic management brought unprecedented pressure. According to information, haikou city road 859 existing with a total length of 1797 km, motor vehicle ownership of 250000 vehicles per day, and are at a 200 rate, of which the amount of private cars is as high as 26%, to the current haikou is obviously can't meet the transportation network of motor vehicle driving demand. Second, the city center area road reconstruction speed slow, to the original road reconstruction is not form system engineering, special is ages ago, DuanTouLu neck road has not been effective reform. Constrain the other major trunk and disperse traffic volume ability. Again, there are pure state road traffic and the lagging problems, such as haikou existing parking lot for cannot accommodate next overmuch vehicles, lead to the driver in some sections on both sides of the parking. This makes originally not wide road become more narrow. There is traffic development, citizens behind haikou travel a single pattern, motorcycles, cars, etc, make travel has become the public preferred way material utilization rate reduced. If the road is sabafish intermediary haikou motorcycles and elegant demeanour car most serious place one of the flood. In the waiting by the shop, packed with motorcycles and elegant demeanour car. They ZhanDao rob guest, obstruct the other vehicles, normal traffic caused easily traffic jam. Haikou traffic police is insufficient, the control points, blind area, people's traffic, too weak, the bus lines concept overlap serious, site layout is not reasonable. Some sections of the serious traffic jam, especially holidays or rush, traffic is chaos.(2) for less than for parking. Data shows, at present, haikou has more than 160000vehicles auto possession, and with more than 20000 cars a year speed increases. The current haikou on an average day with more than 60 new car the road, in a day and added between so many parking obviously is not very practical. In the next few years, whether public or parking garage area will be more strained3.Wide range of reading up to dataHybrid cars advantage is: 1, the hybrid power may according to the average need after the power to determine the maximum power of internal combustion engine, right now in oil consumption is low, less pollution the optimal conditions work. Need high power internal combustion engine power shortage, the battery to supplement; Load for a little while and surplus power can power generation to recharge the battery, due to the internal combustion engine, the battery and sustainable work can constantly, so their trip and charging as ordinary cars. 2, for there is a battery, can be very convenient recycling braking, hill and idle when energy. 3, in the noisy city, can shut by internal combustion engines, battery, to achieve "drive alone zero discharge". 4, with internal combustion engines can be very convenient solve energy consumption of the air conditioning, heating, such as pure electric vehicle defrosting problems met. 5, can use the existing gas station come on, don't have to investment. 6, can let the battery to keep in good working condition, not happened, filling put, prolong the service life, and reduce the cost.Faults: long distance high-speed basic can't save fuel4.PresentationThe essay take about chery Hybird car in china.This kind of car is very useful for every family.because of Hybird car can save petrol .so it’s cheaper than other cars. Sometimes,this kind of cars can use electric it can protect environment also can control the climate change. This very accord with China's national conditions. In the future green cars are very popular to use in the world.翻译新能源汽车作为一种新的汽车产品类型,由于发展时间还不长,技术还不成熟,所以尚未形成一个被广泛认可的概念,但是肯定的是新能源汽车的提出是相对于传统燃料汽车而言的,目前关于新能源汽车的概念根据其定义范围的大小,有狭义和广义两种说法。

Characteristics and Development of Some Kinds of New Energy VehiclesAbstractNow the global automotive industry is facing the challenge of energy and environment,and developing new energy vehicles becomes many global automotive groups’s same plan.But not all of various types of new energy vehicles which have their own advantages and disadvantages can become the most promising future vehicles.I will introduce features and development of Pure Electric Vehicles 、Hybrid Electric Vehicle (HEV)、Fuel Cell Electric Vehicles (FCEV)、Natural Gas Vehicles、Hydrogen Engine Vehicles and DME Vehicles Etc. At last we will know which kind of the new energy vehicles will become mainstream in the future of the car by comparing.Key Word: New Energy Vehicles Future cars HybridHybrid cars is hybrid electric vehicles which use more than one kind of energy provides power to drives the car .
