Pure
electric light off of the comparative advantage and disadvantage analysis with
the progress of Chinese society and the development of the times, electric cars
to energy-saving, environmental protection, lightweight, money, security, and
national and local governments at all levels of electric vehicle support
policies and the progress of science and technology, advantage, within a few
short years occupy one of new domestic energy market.
Cars
and human society as nearly a hundred years of machine of the reason that the
development and changes of the times to electrical era, the information age, and
now in the era of network. Network economy has brought the
development of urban and township logistics, and the whole social logistics
market also presents a prosperous scene.. The new energy vehicles especially
pure electric vehicles in energy-saving emission reduction (motor vehicle
exhaust emissions is one of the important pollution sources of urban PM2.5) and
urban and rural logistics distribution status began to increasingly rapid
highlights, the electric car logistics with comfortable and safe advantages,
broad space for development in the future and become a new force. At the same time, the government
gradually to the new energy logistics car tilt. At present, the new energy vehicle
subsidies and support policies, for the logistics aspects of the system of
systematic subsidies standards starting point is high.
Electric
vehicle mainly uses electric power car, the main battery, motor, control system
composition. The
difficulty lies in the power storage technology, the use of the power battery
does not have the large capacity, high power, high voltage, mileage long
characteristics. At
present, China's new energy vehicle technology bottlenecks still in battery
technology, battery technology still lags behind foreign, investment is a huge
battery technology research and development, related and supporting industries
technical support, battery quality, consistency and stability are to be
improved. Manufacturing cost is further reduced.
At
present, a pure electric car price is at least 2-3 times that of conventional
vehicles, general individual and private consumers is possible not to buy unless
institutions commuter car, large and medium-sized municipal vehicles or large
logistics company can afford. At the same time, the electric car
related facilities are still slightly inadequate, especially charging piles
layout and car enterprises after-sales service are somewhat lacking and not in
place. Also in the process
of operation, if the use of industrial use of electricity, the price at around
1.2-1.5 yuan, and civil electric price is only 0.4-0.5 yuan, if the long-term
use of industrial use of electricity, the use cost of electric vehicles will not
have the advantage.
It is
understood, electric vehicle annual electricity consumption of about 5000
degrees (according to the traveling 20000 kilometers), and per ton of coal can
be made approximately 2500 degrees electric, each car electric vehicle is
equivalent to 1.7 tons of coal burning. With the fuel engine car on the entire
chain generated by the carbon dioxide is basically the equivalent, thus, pure
electric car is neither a new energy vehicles, can really achieve zero emissions
". And pure electric
vehicle mileage is short, high cost, the energy from the power grid, power grid
is about 80% of the power generation by burning coal, and coal conversion and
the phone can not low emissions or zero emissions of new energy.
In
addition, pure electric vehicles in addition to the three pieces of battery,
motor, electric control and electric air conditioning, electric power steering
machine and electric brake three small outside, the key switch tube in tube, the
chip is not the same to their own brand manufacture, must also be a net
importer. More important
is the future of the Chinese government on the new energy automobile subsidies
will be gradually reduce and gradually to cancel, then new energy vehicles
especially pure electric vehicle market is relatively advantage will disappear
completely, we have to advance to face the not evade the reality.
