General electric car preemption Chevrolet Volt sold $41 thousand

In 2009 China power installed capacity of 870 million kilowatts, the same year the Chinese car ownership to 76 million 190 thousand, if all these cars electric vehicles to 10 kilowatts, then a year only these electric vehicles will require 760 million kilowatts of installed capacity of electric power facilities, in other words, in the estimation of car ownership in our country now the era of electric vehicles, China, electric power installed capacity will be doubled in order to cope with the challenges of the popularization of electric vehicles. The electric car seems to be the consensus to replace the traditional automobile, automobile enterprises, experts and consumers have been exploring the human era of electric cars what time will come, but few people noticed that when the human vehicle energy conversion into electrical energy, the power we can bear?

China grid is facing four major challenges

July 27th; “ direct 2030” sustainable transportation series forum third “ electrification — future driving force ” held in Expo Park SAIC GM pavilion. At this forum, a power grid affordability problem that has been easily overlooked by the automotive industry has surfaced. Attended the forum of China Electric Power Research Institute of superconducting power research institute director to well-off, said at the Forum: the arrival of the era of electric cars, will bring great challenges to the grid.

Challenge: electric vehicles the number and type of

To come to a well-off society, the future of the number and type of electric vehicles will bring the most direct challenge to the grid, the increase in the number of electric vehicles, resulting in the increase of grid pressure will be an inevitable phenomenon.

To give off one of the most simple example, he said, Chinese power after more than half a century of development and accumulation, to reach 870 million kilowatts of installed capacity, but in 2009 2009, the Chinese car ownership to 76 million 190 thousand, if the electric vehicle car for all 10 kilowatts, then a year only these electric vehicles will need 7.6 installed capacity of 100 million kilowatts of power. In other words, the accumulation of China's power grid construction for more than half a century, the development of electric vehicles for several years may be depleted, therefore, the increase in the number of electric vehicles, the pressure on the grid is self-evident.

The type of electric vehicles will also bring great challenges to the power grid. In the field of electric vehicles, there are electric vehicles, electric buses, electric cars and other different electric vehicles, these different types of electric vehicles for the power grid, but also a huge challenge.

Challenge two:
In addition, the electric car driving characteristics of the power grid is also a huge challenge, such as travel times, each electric car average daily travel distance, travel time of … … these characteristics are the need to seriously study the issue of power grid companies. To well-off, said, in fact, Power Grid Corp has begun to study the future characteristics of electric vehicle owners of the car, through data analysis, do a good job.

To well-off, revealed that the most concentrated issue of Power Grid Corp research is the impact of electric vehicles on Taiwan area (a substation service area). He said: the Power Grid Corp to enter the &ldquo in Chinese city; the era of air conditioning ” has had a hard time, because of the use of air conditioning is relatively concentrated, so in the early due to inadequate preparation, air conditioning users often encounter in the burning fuse need to use the air conditioning of the phenomenon, that is the problem of Power Grid Corp District planning.

Challenge three: charging habits > The future charging habits of electric vehicle owners are also a huge challenge for Power Grid Corp. As everyone knows, even if it did not encounter the problems of electric vehicles, in the peak period, users often encounter power shortage, if the future popularity of electric vehicles, electric vehicle owners charging time and the peak time of coincidence, so for the grid, will be an insurmountable challenge. To a charging time said that the ideal situation is the owners of electric cars and electricity peak staggered, “ &rdquo, the valley filling effect; the charging time of the owner of the concentrated in the 11 pm to 6 am the next day.

Challenge four: charging facilities layout and construction of

Come off said that the layout and construction of charging facilities also need to take seriously the problem, each regional centralized electric vehicle types, large capacity, are planned in advance, otherwise, if the average distribution in some electric buses, electric car rental concentrated area, there will be charging infrastructure construction lags behind the problem, which brings hidden trouble to the operation of the entire society.

To come to a well-off society, the arrival of the era of electric vehicles is not as easy as we imagined, it requires the whole society supporting, especially the follow-up of the grid supporting facilities. Including the upgrading of the existing distribution network, the number of new installed capacity, are issues that need to be seriously considered.

However, although the era of electric vehicles will bring great challenges to the grid, but in the view of well-off, the arrival of the era of electric vehicles, the development of the grid also has great positive.

Off to say: “ we all know that unlike other electrical products easy to store, the Power Grid Corp also for how to store electricity to the electric vehicle is an opportunity, because the electric car battery is natural.
To off that electric cars can help power storage, because of different car air conditioning, TV and other household appliances, it is actually a battery battery, can help the Power Grid Corp of the power reserve, if the future popularity of electric vehicles, the electric vehicle storage power is very considerable.

It is for this reason, to the well-off said: “ electric car era will bring disruptive problems to the power grid, the grid will only bring to more efficient operation, the smart grid era may be with the electric car era, coming together.
General Motors announced last week that some Chevrolet dealers in the United States have begun to accept orders from Chevrolet Volt range - added electric vehicles. Chevrolet Volt range based electric vehicle retail sales in the United States is 4.1 million U.S. dollars (about 280 thousand yuan), in addition, consumers can get the highest $7500 individual income tax credit amount from the U.S. Federal government. GM also announced that Chinese and Europe in the fourth quarter of 2011 formally introduced by the industry as “ electrification of the automobile pioneer Chevrolet models ” Volt extended range electric vehicle, they will also become the world's first foreign market by Chevrolet Volt.

In the United States market, Chevrolet Volt extended range electric vehicle will be available later this year, the first in California, New York, Michigan, Connecticut, Texas, New Jersey and Washington state limited sale. GM also offered a 36 month, $2500, down to $360 monthly rental program for Volt consumers in the United states. GM will also provide an unprecedented 8 million mile (160 thousand km) warranty period for Volt electric vehicles for the next /10 years. In the United States, Chevrolet Volt owners can directly use standard home 120 volt power supply for Volt charging. In addition, the top 4400 customers who buy Chevrolet Volt will also get a free 240 volt charging station, and enjoy free installation of home service.

Chevrolet Volt is the only one in the market that can be all-weather, all road traffic models, and eliminate the limited battery mileage mileage restrictions. Through the continuous power supply of vehicle mounted generator, the maximum mileage of Volt is more than 500 kilometers. When the mileage is less than 60 kilometers, the Volt electric vehicle can be driven by the power of the 16 kwh lithium-ion battery on board, and can realize “ zero fuel consumption and zero emission ”.

When the Volt vehicle battery power consumption reaches the minimum critical limit, the vehicle mounted generator will automatically start to provide power for the Volt, so as to achieve the driving capacity of up to 480 kilometers or more.

In fact, in the ongoing 2010 Shanghai World Expo, Chevrolet Volt as a VIP reception car has been put into use. And Chinese consumers will also be in the fourth quarter of 2011 to achieve the Chevrolet Volt range of electric vehicles desire. But GM says it will not produce this car in China for the time being.

The day before, the first car Chinese for individual consumers of pure electric vehicles sold in Hangzhou Zotye 5008EV. The car uses a lithium ion power battery, the maximum power 27KW, maximum speed up to 110km/h, the use of ordinary civilian power 220V 6~8 hours to full charge, fast charge mode using 380V special power, in 20 minutes 80% of full power. The driving range of one charge is more than 200 kilometers, and the power consumption is 12 degrees per hundred kilometers. After enjoying the state subsidy of 60 thousand yuan and Hangzhou local subsidies, consumers actually pay the price is 108 thousand yuan.

4 driverless Piaggio Porter van from Italy Milan, all the way up to Shanghai for World Expo. This is a real test of artificial vision and intelligence systems, led by VisLab technology. In order to ensure safety, in the road, the electric automatic driving MPV will not really drive under unmanned supervision, an engineer will sit in front of the steering wheel, monitoring the action of the vehicle, in order to prepare for accidents. Team trip is about 1.3 million kilometers, is expected by the end of October arrived in Shanghai in World Expo.
