Beijing issued a standard electric vehicle charging station and the space Bridge, Ma F, small business, benefits such as land to build four charging stations. 2010 Beijing Auto Show, the launch of 95 models of new energy vehicles. Beijing 1060 will be added this year, sanitation pure electric cars, 100 electric buses, and plans to promote electric taxis in the suburbs Demonstration. However -
2010 to 2020 the development of new energy automotive industry programmatic document – the “energy saving and new energy vehicle development plan,” the draft has been scheduled in preparation for the State Department reported in August, can be promulgated after the adoption, which relates to the development of new energy automotive industry approach, scale and key components of the R & D, marketing and supporting facilities. It is understood that technical line of new energy vehicles in order to present the basic identified as the main electric vehicles, a variety of new energy automotive technology development model of the coexistence line dell Vostro A840 battery .
Now, the development of new energy automotive industry has become the consensus of the global automotive industry. According to forecasts, by 2015, global sales of new energy vehicles up to 7 million. By 2020, electric cars and other “green” car sales in developed markets will reach one-third of total global sales.
The future of new energy vehicles how to “popular and critically acclaimed”? The industry believes that the current need to break through the three major difficulties: First, R & D, the second is to reduce the cost price, the three universal charging equipment and facilities.
Limited battery life of different interfaces
863 plan and new energy saving cars of major projects introduced supervision and consultant team leader Wang Binggang, “Power” is a new energy vehicle development, “Technical bottlenecks” to pure electric vehicles, for example, currently there are two main problems: First, the battery cost is still high, the lower the energy density of batteries, electric cars brought high prices, vehicle weight, mileage driving charge short follow-up issues; second charge for a long time yet to establish a convenient charging network dell Vostro A860n battery dell Inspiron XPS Gen 2 battery .
For ordinary consumers, electric cars and the largest difference between ordinary car, it is reflected in the battery life and cost. The current battery life are not like gasoline engines to achieve low maintenance costs, as under the lifecycle. This is also plagued electric vehicles to promote and popularize a major obstacle.
The batteries many problems, for example, the current cost of new energy vehicles battery is about 3,000 yuan / kwh, the cost of electric vehicle battery is the highest proportion around 33% of the cost for the complete vehicle -50% the cost of the battery must down, and the need to achieve mass production and the domestic production of raw materials; battery interface, different, as different brands of mobile phone charge port is different, “standard” of uncertainty, would have great impact on the development of electric vehicles; because of battery life with restrictions, whether each charge should have a counting device for easy battery replacement drivers; transformer which better use is 380 volts or 220 volts? It also requires higher voltage; and the current chaos in the market for electric bicycle battery compared to the birth of the future electric vehicle market in the true sense whether the battery and complete battery manufacturing giant rental, recovery, secondary manufacturing industry chain, etc. These are electric vehicles and charging stand the process of development problems dell XPS M1210 battery dell XPS M1330 battery .
Can not “call at any time” charging time-consuming
Worry about halfway power breakdown and can not find the charging station is that many potential users of electric cars common concern.
At present, China’s own production of new energy vehicles, power consumption per 100 km is about 16 degrees, according to different price and cost about 12 yuan. Fuel consumption of 8 liters and 100 km of conventional fuel vehicle compared to an estimated savings of 2 / 3 of oil costs. But the charging infrastructure is not mature and take shape in the car charging station only with the city of Shenzhen, Chengdu and Shanghai a few. How to build charging stations as soon as possible, while heavy traffic flow locations to install portable charging pile, built in the large parking lot with a pile of parking charge, so that electric cars to enjoy the “always calls” the feeling is critical.
On the other hand, each charge is also a problem for too long. Car charger with fast charge and slow charge two, usually 10 minutes fast charge to 70% of the charge, but detrimental to battery life. Charging car from scratch, you need 3 hours to full dell XPS M1530 battery dell XPS M140 battery .
“In the future, people walking, cars driving friction with the ground when the energy generated will be collected and converted into electrical energy stored in the roadside charging stations. Auto power is low, the driver if the car parked next to the charging station, set cars and charging stations in the radio frequency device will automatically sense, the completion of charging the car. “outlines the future of car showrooms in the picture, people long for.
Each other can not replace conventional cars
China’s new energy vehicles can be divided into new fuel, gas, bio fuel, ethanol fuel and electric five categories. Including oil, electric hybrid and pure electric vehicles, will be the largest concentration of new energy vehicles in the future development of type dell Inspiron XPS M170 battery dell Inspiron XPS M1710 battery .
Wang Binggang, said a new energy and drive technology can have a promotional advantage, need to have four elements: the availability of energy, environmental friendliness, economy and ease of use. For electric vehicles, the first two no doubt that the latter two are still a lot of current problems. For successful promotion of electric vehicles, car must be substantially reduced with the use of cost consumers as much as possible to improve the convenience charge.
Wang Binggang also believes that, by the battery energy density and price De restrictions, the same weight and cost of electric Qiche up less fuel vehicle performance Chuan Tong, Jishiqianglai have Tigao battery power density, but also may have security and cost challenges, also That is, with the practical development of the new system battery, not a short period of time can be achieved.
The hybrid technology and advanced internal combustion engine technology is a modern vehicle power system innovation are two important directions, are also present in Chinese automobile enterprises to increase investment in hybrid vehicles dell XPS M1730 battery .
Fuel cell vehicle technology has rapidly improved, but fuel cell vehicles need to build a dedicated hydrogen refueling station, hydrogen transport, storage, there are difficulties.
The above considerations, Wang Binggang suggest that, at and for a long period of time, new energy vehicles still can not fully replace traditional fuel vehicles, a reasonable proposal, several cars from each other, work together to build the future structure of the new road traffic. Such as the range of 10 kilometers, recommended bike, electric bike, mini electric tricycle; activities within the range of 50 km, proposed micro-or small-scale electric vehicle; dell XPS M2010 battery range of 100 kilometers, recommended plug-in hybrids or by electric vehicle program; the range of 100 kilometers or more, recommended fuel vehicles, fuel cell vehicles, liquefied natural gas vehicle.
