New energy vehicles
New 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.Introduction
Chery 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 \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.

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 \conservation and environmental protection technology platform construction project\get \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 business 2.Main discussion
1. The advantages of new energy vehicles (strength) analysis
The 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, \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 160000
vehicles 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 strained 3.Wide range of reading up to data
Hybrid 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 \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 fuel 4.Presentation

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。
广义：使用了除汽油和柴油等石油能源作为动力来源的汽车。
狭义：采用非常规的车用燃料作为动力控制和驱动方面的先进技术，形成的 技术原理先进，具有新技术，新结构的汽车。 新能源汽车包括燃料电池汽车、混合动力汽车、氢能源动力汽车和太阳能汽车等。 混合动力汽车是指车上装有两个以上动力源：蓄电池、燃料电池、太阳能电池、 内燃机车的发电机组。
当前混合动力汽车一般是指内燃机车发电机，再加上蓄电池的汽车。
优点：
车辆启动停止时，只靠蓄电池带动，不达到一定速度，发动机就不工作，因此，便能使发动机一直保持在最佳工况状态，动力性好，排放量很低，而且电能的来源都是发动机，只需加油即可。其原理简单来说就是电动机和发动机的合理安排组合输出动力。
缺点：有两套动力，
再加上两套动力的管理控制系统，结构复杂，技术较难，价格较高且长距离高速行驶基本不能省油。纯电动汽车是完全由可充电电池（如铅酸电池、镍镉电池、镍氢电池或锂离子电池）提供动力源的汽车。
纯电动汽车以电动机代替燃油机，噪音低、无污染，且因使用单一的电能源，电控系统相比混合电动车大为简化。降低了成本，也可补偿电池的部分价格。纯电动车主要用于机场、社区、球场等地方。
缺点：仅限于某些特定范围内应用，市场较小。主要原因是由于各种类别的蓄电池，普遍存在价格高、寿命短、外形尺寸和重量大、充电时间长等严重缺点。 燃料电池汽车是指以氢气、甲醇等为燃料，通过化学反应产生电流，依靠电机驱动的汽车。其电池的能量是通过氢气和氧气的化学作用，而不是经过燃烧，直接变成电能的。燃料电池的化学反应过程不会产生有害产物，因此燃料电池车辆是无污染汽车，燃料电池的能量转换效率比内燃机要高2～3倍，因此从能源的利用和环境保护方面，燃料电池汽车是一种理想的车辆。
