Electric vehicle batteries, buy or rent?

Electric vehicles, as gradually as bikes in public life popularized. Yangzhou city firm recently launched a rental battery battery service, has created quite a stir. Rent or buy? Many people began to plan together.

Trouble: several hundred dollars per year for battery

Mr. Home a year ago bought a electric car, but now how long the ride would not charge. “Merchant said I batteries are used improperly, leading to shorter battery life, and now need to replace the battery.” Mr. Habitat learned about electric car battery market, the average brand they have to several hundred dollars.

Firm in a battery electric vehicle, the reporter also met Ms. Shi to buy batteries, she said: “At home, three motor vehicles every year to this time we should change the batteries.” Ranks as Mr. and Ms. facilities such as electric vehicles Battery replacement lot of trouble many people.

Initiative: leasable electric car batteries

Urban, a battery firm, operating battery maintenance businesses, recently launched a battery electric car rental business. Section 4 yuan per month, including three 36-volt battery also only costs 12 yuan a month. The introduction of this service, so that both are fresh and some people did not understand, the batteries can also be rented?

Mr. Xu told reporters that the firm owner, launched the service less than a month, it made more than 60 single-business. He said: “limited tenure, pay some deposit fill in a procedure on the line, our quality control, customer ease of use, this approach very attractive to the public.”

Wondering: rent or buy, which is more cost-effective?

Mr. Xu boss calculations, calculated in accordance with 36-volt battery, new battery life generally 18 months, but most people are used improperly, this life is also reduced. He said that according to 12 yuan a month rent calculation, 18 months spent 216 yuan, but at least buy a new 400 yuan or so. Rent battery, allowing the public to reduce 1 / 3 battery investment.

Many people said that this new consumption patterns for the feeling of some incompatible. Mr Zhou said the public, rent the battery, after all, not their own, even bother keeping, say, rent the battery enough security? How to use the process of division of responsibilities? Many people hope that the details of the market can be more standardized.

Industrial battery industry market

Industrial battery industry market

The gap between technology and manufacturing a profound impact on the market, industrial battery industry

"The more you look, the less you know" is no doubt we are in the process of writing this report most experience.

We have been thinking, what is the power of the battery industry? We believe that every application of new materials for a qualitative leap in battery performance, each anode and cathode materials also contributed to the improvement or electrolyte batteries have a certain level of quality improvement.

History of the battery, it is a material advancement of technology history. Quantitative improvement of the battery technology, the invention of new materials to promote qualitative change in the battery. Can be expected, the use of conductive material containing the element lithium (ionic compounds, polymers) as the electrode material is the best choice for high-energy battery, but, multi-element compounds found in lithium-ion materials technology needed to continue to progress.

Enhance the energy storage potential, improve energy density, this battery technology is always evolving concept of one of the most direct. However, the perfect person does not yet exist, especially for high power and high energy is difficult to have both. Moreover, we will find that different products have diverse needs of the battery.

Thus, the development of battery materials is diverse.

Contrast the appearance of performance, safety, price, life are all indicators must be considered, which determines whether certain widely used battery. Because, superior performance lithium-ion battery, different cathode materials for lithium ion batteries to meet the cost differences between market demand for different applications, therefore, the formation of lithium-ion battery cells for other types of alternative trend is almost full.

Despite our impression that the battery is labor-intensive manufacturing, but the battery industry chain from the point of view, is also a technology-intensive, especially in resource mining and processing and battery materials preparation more involved in materials science. Lead-acid batteries through the icon, nickel hydrogen batteries, lithium-ion batteries manufactured by the main process areas, we pointed out the direction of development of the domestic battery industry and technical bottlenecks.

In the battery industry, China and Japan, there is a considerable gap between the United States, which ultimately can be reflected in the materials technology gap between the domestic and foreign industry. We believe that relying on imports of battery materials, the manufacture of small single cells are mature; But even solve the problem of battery materials, high-capacity high-power battery pack design and manufacturing continues to face many problems, which is the electric vehicles battery technology needs to break the key technical difficulties.

Business transformation from the perspective of the development of China Battery, Lithium-ion battery industry competitiveness in the market depends heavily on the accumulation of long-term development of the technology, rather than pure capital investment, and similarly, lithium battery materials with high technical barriers, the small sub-industry leaders who are mostly early entry into the industry. However, the small lithium ion battery business, technical threshold is low, the influx of a large number of small participants led to the rapid decline in industry profitability.

Changes ushered in the third mobile phone battery

Changes ushered in the third mobile phone battery

Recently, the State Council officially approved the 3G licensing program, which marks China's third generation digital communication network construction officially began. Coincidentally, most closely connected with the mobile phone battery also ushered in a historic breakthrough. Recently, China's leading battery manufacturer company officially announced the launch of Scud TP - China's "third-generation mobile phone batteries."

It is understood that the development of mobile phone battery has gone through two phases, the first generation of mobile phone battery is only a single model cell phones only for a single. After the second generation of the first generation of mobile phone battery to be improved on the basis of a single model battery can be applied to the same brand of a variety of mobile phones, such as the SL-BL-5C battery can be applied to more mobile phones such as Nokia 3310,3610. And now, Scud "third-generation mobile phone battery - TP Electric," the advent of innovative technologies to improve the previous generation, so that the "single model battery can be applied to a variety of multi-brand mobile phone" from the idea into a reality. Such as the SL-1112A-D30945 battery, in addition to more models for Nokia phones, but also can be used for a lot of the same size battery or other devices. Compared with the previous two generations of mobile phone batteries, the third generation mobile phone brand broke through the restrictions. When users buy cell phone batteries, mobile phone brands no longer have to worry about the restrictions.

Some experts said that the third generation of mobile phone battery TP advent of electricity, not only brings convenience to mobile phone users will also bring a different brand of mobile phone sales. It is understood that, at present, mobile phones on the market an unprecedented range of categories and models, coupled with an unprecedented hot cottage, creating a large number of different brands and models are generic cell, causing consumers can not buy many types of mobile phone batteries, dealers are also no sales, the original model developed by the battery dies way the market has been far behind the pace. The third generation of mobile phone batteries power the emergence of TP, just to solve this problem.

It is understood that Scud TP electric model is complete, almost all are still on the market supporting the use of mobile phones, models about models around 5000. This is 5000 not only covers a variety of mobile phone batteries, Nokia, Samsung, Motorola and other major international brands, but also covers the domestic Huawei, Lenovo, Jin and other domestic brands, but also includes domestic and international thirty-five yards brand.

Industry experts said the Scud this innovative research and development, not only for the optional battery offers consumers great convenience, it is a mobile phone battery in the history of the major changes, TP advent of electricity, mobile phone battery is a new milestone in the history of the development.

Garbage dump into a power station

Garbage dump into a power station

A New Jersey called "1-E" in the garbage dump a lot of rubbish buried in the past few decades. Now "1-E" landfill has been transformed into power stations. The waste generated by the decomposition of methane gas as fuel for generating electricity used in New Jersey thousands of families.

Energy transfer

"1-E" landfill in Kearny, New Jersey, the town, an area of nearly 1.62 square kilometers. Over the past few decades, a large number of buried garbage dump where garbage and construction waste.

Today, "1-E" landfill has been converted into power stations, members of management from the New Jersey Meadowlands. Waste generated by the decomposition of methane gas as fuel to produce electricity. These thousands of electricity for New Jersey families to use.

26, the Associated Press quoted Meadowlands Commission is responsible for solid waste and natural resources were the words of Tom reports: "It's like you buy in a different way to their own garbage."

New Jersey Public Utilities Commission, according to statistics, New Jersey, now a total of 21 garbage stations, "1-E" is one of them.

The number of garbage power plant in New Jersey and Texas, the same. However, Georgia, Mississippi, Louis Arizona, Arkansas, and Oklahoma, the number of garbage power plant in New Jersey less than the sum of the number of garbage power plant.

New Energy

New Jersey, an authority in accordance with the idea of environmental protection experts, in order to make full use of landfill space, the United States the future of garbage power plant will also introduce wind and solar power.

U.S. Environmental Protection Agency, "Mountain Club" administrative charge said: "We see landfills as potential New Age energy plants. Because the comprehensive utilization of waste power stations can be wind, solar and waste to form a stable power source. "

Meadowlands Board said the establishment of wind farms in the garbage power plant will take some time, because the open space area of landfill constantly change. But the Meadowlands Commission has planned to "1-E" landfill in the southern area of 80,000 square meters to install solar panels.

New Jersey Governor Jon Corzine in the energy control program, said the waste methane produced by the treatment of renewable energy is an important one. State government hopes that by 2020 30% of New Jersey, electricity provided by the biogas power generation.

Environmental benefits

Microorganisms in the garbage to eat organic matter and produce methane. Biogas as a new energy, good environmental protection.

Mare estimate, "1-E" landfill gas will continue to collect more than 20 years. He said the Meadowlands District 4 garbage power plant to provide electricity to 2.5 million households.

Federal Environmental Protection Agency said that at present there are 455 U.S. landfills provide power using biogas generated. Environmental Protection Department in the waste gas expansion project, plans to establish more than 500 in the United States this type of garbage power plant.

New Jersey Clean Energy Public Utilities Commission head Michael temperature card, said new landfills in New Jersey must have a gas collection facilities.

Mare said that people used to think that is a waste landfill space, but they are becoming able to contribute more to society.

Lithium Battery Energy saving Upsurge

Lithium Battery Energy saving Upsurge

With the constant fluctuations in international oil prices, energy saving environmentally friendly lithium battery in the limelight once again a hot topic. From 6 months, the number of international auto companies and electronics companies are using large-scale lithium battery joint investment. Including Toyota and Matsushita, Nissan and NEC, Volkswagen and Sanyo, Bosch and Samsung, they believe that lithium batteries in the next few years will gradually replace the nickel-metal hydride batteries, lead the direction of development of hybrid vehicles. Li-ion battery in the heat of global investment background, China's automotive enterprises in this research work is in what kind of? Experts on the lithium battery is holding what kind of attitude? Recently, the reporter interviewed specifically on this issue who has studied the domestic lithium battery, several experts.

Beijing Institute of Electric Vehicle Engineering Center Deputy Director Lin Cheng

Study of lithium iron phosphate has been a breakthrough

Lin Cheng told reporters, demanding automotive lithium batteries. It requires that the vehicle used in a variety of conditions, must protect the security, can not occur fire, explosions and other accidents. The first was for battery electric vehicles, in this country has made great breakthroughs have begun to take industrial scale. But 5,6 years ago, with the battery powered vehicles are often some accidents, such cells will gradually be diluted. Now, the domestic lithium battery research progress quickly, especially in the battery safety issues, has made great progress.

Lin Cheng told reporters, lithium batteries include lithium manganese oxide and lithium iron phosphate batteries. At present, the development of the domestic lithium manganese oxide has begun to take shape. Lithium iron phosphate as safer, longer life, will become an important direction for future development of lithium batteries, but also abroad, the focus of research and development of the automobile. At present, lithium iron phosphate studies of good progress, especially in some of the patent on a breakthrough, this time for the Beijing Olympic Games is a passenger car with a self-developed lithium iron phosphate lithium battery.

"Of course with the study abroad compared to lithium batteries, the domestic lithium battery research still lags far behind, but the domestic lithium battery emphasis on increasing, the future will be the R & D focus." Lin Cheng told reporters.

Henan Huanyu Group lithium battery industry technology Deng Lun-ho, deputy chief engineer

Large-scale lithium batteries for electric cars need some time

Henan Huanyu Group is a component from the battery to the battery cell manufacturing plastics and related hardware, equipment manufacturing, electronics manufacturing, a complete industrial chain of the Enterprise Group, has undertaken the project of Science and Technology Li-ion battery research and development.

"At present the domestic lithium battery research and abroad, the gap is mainly reflected in the battery control system and power management systems." Deng Lun-ho told reporters that now the domestic lithium battery research for development in their respective state. Currently, some companies have been able to provide the corresponding lithium battery electric vehicle accessory products, supporting the general lithium batteries can run 200 to 500 km.

Deng Lun-ho told reporters that now the price is too high the domestic lithium battery, power management system problem has not yet been well resolved. Charging electric vehicles also face the problem. Currently, the general line at home can not charge lithium batteries for electric vehicles must be equipped with a small dedicated charger, and charging time is very long and very troublesome. Abroad, in order to solve this problem, generally regarded charging stations and gas stations together. China is now charging stations have not established a large scale.

Deng Lun-ho believes that the current consumer acceptance of electric vehicles equipped with lithium batteries it still more difficult: "the price of an ordinary electric car is about twice the same configuration or even higher gasoline locomotives, domestic consumers have not enough economic prepared to accept the power and electric vehicles. "

China Electric Power Research Institute engineer Chuang Feng

Optimistic about the prospects for the development of lithium iron phosphate

Chong Tong, told this reporter, the electric vehicle battery research and development work has gone from lead-acid batteries, nickel-metal hydride batteries to the development of lithium batteries, each battery advantages and disadvantages.

The earliest to appear in lead-acid batteries, used in the longest time, belonging to the battery series. The best safety performance lead-acid batteries, rare explosion, fire and other phenomena, energy storage effect is not ideal. Later, people developed a nickel-metal hydride batteries, store energy and power than the effect of the ideal lead-acid batteries, but due to nickel-metal hydride battery in the charging of hydrogen generated in the process prone to explosion, so the nickel-metal hydride batteries in a business may or may not state.

To the year 2000, people developed a lithium battery. Lithium batteries are lead-acid storage battery of power 2 to 3 times, but because it contains lithium-ion active in the metal layer surface, prone to spontaneous combustion in the air, explosions, etc., higher risk. So now the major countries is to control the development of lithium batteries is safety and stability.

"Charging a lithium battery would be able to cycle around 1000, in which the stored energy of lithium iron phosphate is better than lithium cobalt oxide and lithium manganese oxide effects worse, but it's the best safety performance, than lead-acid battery energy storage much higher, so now the most promising lithium iron phosphate. "Chuang Tong said.

Society of Automotive Engineers of China, director Chen Quanshi branch of electric car

Three problems of domestic lithium battery research

Quan-Shi Chen said in an interview: "Now the state attaches great importance to the study of lithium batteries, '863 'project, the state invested a total of 66 million yuan, all development work for the lithium battery. We and Japan, the United States such as walking in the lithium battery research and development in the forefront of the developed countries, China's lithium battery manufacturing precision, equipment, standards, etc. there is a certain gap between R & D details. "

Quan-Shi Chen told reporters that at present there are three issues of domestic lithium battery research. The first is the consistency of manufacturing. Since the lithium battery manufacturing technology and equipment there is a gap, the domestic lithium battery production technology mixed, manufacturing standards has not yet reached agreement. Lithium batteries used in electric vehicles are connected in series or in parallel, if the consistency issues are not well, then the large-scale production of lithium batteries used in electric vehicles will not be able.

Followed by the intellectual property rights. Currently in the study of lithium iron phosphate has made a breakthrough, but the U.S. patent in this area, so although some of our links to independent research and development, but in intellectual property issues, but also do not know how to respond.

The third issue is the selection of raw materials. Now the production of raw materials used in lithium batteries can not all imported, mainly from China, but domestic raw materials, through international certification, to produce lithium-ion batteries in order to be internationally recognized, so the link in the certification of raw materials and also some problems.
