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
lized: used in gasoline
and diesel oil as power source of the
l: 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 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
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
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 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 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 old car is more
and more, oil prices more and
more expensive,
every car company began to research and
development of new
energy vehicles.
uction
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

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
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
prizeand 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
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 discharge4,
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
tation
The essay take about chery
Hybird car in kind of car is very useful for
every e 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.

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。
家用汽车越来越多,石油价格越来越昂贵,每汽车公司开始研究和开发新能源汽
车。

2.主要讨论
1.新能源汽车的优势(Strength)分析
国家信息中心预测,中国乘用车市场的增长情
况将至少再持续15年,年增长
需要大约相当于1.5倍左右的GDP增长。2009个汽车进入家庭(
中低收入家庭购
买能力)。从定性的角度,汽车市场也将有至少20年的快速增长。如果国内
g
dp2020年比2000年,约2020年我国将超过美国,汽车需求量将达到20000000辆,
成为世界最大的汽车市场。
自1988以来,在福建省,成为最大的经济特区,自海口市成为海
口市赢得了
十大城市,海南省的省会城市,国家环境保护模范城市,国家卫生城市,中国优
秀旅
游城市,国家园林城市,国家历史文化名城,全国文明城市先进城市工作,
城市环境综合整治,“中国优
秀城市人居环境奖”等城市的声誉。海南岛上的持
续发展,环境保护岛旅游健康岛,新能源汽车,是城市
的一个环境与健康。从经
济发展的前景和海口市汽车市场的发展规模,在城市看到的公共交通,出租车,
商业,环卫和邮政等公共服务和其他领域,新能源汽车,有一个很大的市场空间。
2.新能源汽车的缺点(缺点)分析
(1)交通拥挤,混乱。近五年来,海口的机动车和驾驶
员的数量持续增长,道路
交通管理带来了前所未有的压力。据了解,海口市859路和1797公里的总
长度现
有机动车250000辆,每天的所有权,并以200的速度增长,其中私家车的数量高
达26%,目前海口显然不能满足需求的交通网络机动车驾驶。第二,城市中心区
道路改造速度慢,对原
有道路改造是没有形成系统的工程,特别是年龄前,断头
路颈路还没有有效的改革。限制其他主要干线和
分散交通量的能力。再次,有纯
态道路交通和滞后的问题,如海口现有的停车场不能容纳下过多的车辆,
导致在
停车双方在一些路段驾驶员。这使得原本就不宽敞的道路变得更窄。有交通的发
展,公民
在海口旅行的一个单一的模式,摩托车,汽车,等等,使旅游已成为市
民的首选材料利用率降低。如果道
路sabafish中介海口摩托车和风采车最严重
的地方之一,洪水。在等候的商店,挤满了摩托车和
汽车的风采。他们占道抢客,
妨碍其他车辆正常通行,容易造成交通堵塞。海口的交通警察不足,盲区,
控制
点,人们的交通,太弱,公交线路的概念重叠严重,站点布局不合理。对严重的
交通堵塞的
某些部分,特别是节假日或繁忙,交通混乱。
(2)不停车。数据显示,目前,海口已超过16000
0辆,汽车保有量,与20000多辆
汽车一年的速度增加。目前海口平均每天有超过60的新车路,在
一天,如此多的
停车场之间的明显不太实际。在接下来的几年里,无论是公共或停车场的面积会
越紧张
3.读到的数据范围
混合动力汽车的优点是:1.混合动力可以根据平均需要
的功率来确定内燃机
的最大功率后,现在的石油消耗低,污染少的最优条件工作。需要大功率内燃机功率不足,电池来补充;一会儿,多余的电能发电的电池充电负载,由于内燃机,
电池可持续的工作
中能不断的,所以他们的旅行和普通汽车充电。2.因为有了电
池,可以十分方便地回收
制动能量,希尔和空闲时。3.在喧闹的城市里,可以通
过内燃机,电池关闭,实现“单独驱动零排放”
。4.内燃机可以很方便的解决空
调,采暖能耗,如纯电动汽车除霜问题。5.可以利用现有的加油站加
油,不必投
资。6.可让电池保持在良好的工作状态,不发生,充放,延长使用寿命,降低成

。
缺点:长距离高速基本不能节省燃料
4.介绍
本文以奇瑞混合动力汽车
在中国。这种车是非常有用的混合车每我家可以节
省汽油。所以它比其他车便宜。有时,这种汽车可以使
用的电能也能控制气候变
