Household 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 just
3 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

engineering technology research
center
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-

electric car key
components and core technology, the company has
formed a set of

the motor, motor drive system,
DCDC, 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

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,
environment prize
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
very convenient solve energy

and reduce

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
