1、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 ene
2、rgy 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 f
3、ormation 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,Turbi
4、ne 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 conditio
5、n, 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,Compl
6、ex 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 elec
7、tric 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
8、 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 refer
9、s 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 pr
10、ocess 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 v
11、ehicle. 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 independe
12、nt 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
13、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 resear
14、ch 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
15、 key components and core technology, the company has formed a set ofkey 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
16、 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
