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.
