popular battery

A recent survey revealed that in Shenzhen, a number of stores selling mobile phones battery price tag false, but also in Shenzhen has formed a clear division of labor radiation leaving the country battery mobile phone chain industry. Original price of mobile phone battery is typically between 100-300 yuan,    laptop battery rechargeable  while the secondary battery refurbished or even as long as a few dollars.

Experts said that as the current domestic ownership of mobile phones reached 400 million euros, the battery is the large number of accessories, and gradually around counterfeiting is rampant, if consumers buy mobile phone downloads not only do not mind the use of authentic products, it is likely to be victims of battery explosions.

Genuine Mobile phone battery will be sold to buy counterfeit batteries make the difference

Shenzhen Industrial and Commercial Bureau to start the fight against counterfeit mobile phone batteries for special actions, Saige Industrial Building, Huaqiang North, seized more than 6800 pieces of Samsung,   dell inspiron 8600 battery  Motorola, Sony Ericsson mobile phone batteries and other issues, including more than 4,000 pieces of batteries of Nokia mobile phones.

“At this moment we all thought it was wrong to mobile phone batteries.” The city of Shenzhen Industry and Commerce Bureau Chief Economic Inspection Xi Huang said, but the results of further tests have surprised more than 4000 pieces Nokia mobile phone battery went up all authentic. According to the confessions of suspects, these batteries are purchased from a wholesaler of northern China, came to Shenzhen to buy from the wholesaler will be real batteries of mobile phones sold, and purchase the counterfeit batteries to make a difference.

Huang Xi said earlier, for the network license, three decks of cards, ask for an invoice, identification of the new combined approach, now well known and used by consumers, but if it is original phone batteries portable goods are often neglected. As everyone knows, the sales of mobile phones of their own profits is not high on the door of the original battery,   sony vgp-bps13 battery has become an important activity of our days, some unscrupulous means to make money.

According to experts, the battery on the market today is divided into public, parallel imports, and three kinds of fakes. What is the licensed production of cell phone manufacturers original batteries, the price is usually between 100 yuan to 300 yuan; parallel imports is dedicated to a mobile phone manufacturers battery original batteries manufactured counterfeit batteries, the price is usually less than 100 yuan, and counterfeit goods is a waste of batteries used refurbished hand, the price is usually between 20 yuan to 30 yuan, but only a few dollars cheaper. By this calculation, if the trader to take such underhanded tactics, each mobile phone, you can earn 100 yuan profits.

The production of counterfeit batteries in Shenzhen has gone to town

As the largest center of China’s electronics distribution, Shenzhen Huaqiang North, computers, printing supplies, electronic components are famous throughout the country, including mobile phones and mobile phone batteries. Huaqiang North, along the distribution of Wang Yuan, Ming Tong, SED, etc. 31 large and small,   apple a1245 battery Electronic City phones, they are mobile, the main platform for commercial products.

Chen, Zhanjiang City, DVN Tung have stalls, the reporter as he entered and found the digital city, where the distribution of hundreds of thousands of stalls, each stall is only 12 square meters, only one shelter . Mr Chen told reporters he was four years ago, came to Shenzhen to make a living at home, primarily to OEM business is mobile, the price of this phone will not exceed 1,200 yuan, and rich in features, there is no licensing system.

OEM shipments of mobile phones is huge. Mr. Chen said that the peak of the day, it can be sold to more than 1,000 mobile phones, each earning 10 yuan trading. The buyers are mainly wholesalers, to return to the mainland and sold in rural areas. Northwest because of the level of consumption is not high, it was the sale of key areas.

As for cell phone batteries, Mr. Chen said that since the overall price of mobile phones sold is not high, it is difficult with a license, the general use of parallel imports on the drums, and sometimes used false. He said the production of counterfeit batteries in Shenzhen has been everywhere. Manufacturers start with some of the trash basket for a few cents per unit price of a mobile phone to redeem the old batteries through various means of spin-off cells inside the battery,   ibm thinkpad t40 battery look for a factory mold bought a new shell after a simple production and assembly, coupled with labor costs, the total cost of only a few dollars.

Experts: Consumers should buy battery brand

Shenzhen B & K Electronics Co., Ltd Technical Director Huang Sui-yang said, batteries for cellular phones with batteries, circuit protection and allocation of three parts. Batteries base of the battery, due to problems of product quality caused by a short circuit, this will lead to high temperature and pressure, there is a risk of explosion. The reason for the high price of batteries original equipment, it is because of additional safety devices for protection.

The fake batteries usually cheap, have not reached the national standard batteries and materials, and some have even failed to protect the circuit or circuit weld joint protection, cold aging. Moreover the use of recycled materials, used batteries to the production. The use of such material, lighter batteries were damaged, cell phones, in severe cases May cause spontaneous combustion, explosion, caused considerable damage to the user.

In this regard, first of all CTTL Gui Li said that the country has long been to develop safety standards for cell phone batteries, the key is whether full compliance with the standards of the manufacturers do, and seriously applied. He said that following the standards of the imposition of cell phone charger, national authorities should develop uniform standards of mobile phone batteries, and should be launched late this year.

He Gui Li said that the Ministry of Information Industry to do now is cell phone batteries, as dry as the standard classification. As the battery There are several models of different sizes,   sony vgp-bps8 battery  such as cell phone batteries may also develop criteria for three or four different sizes, each size of the metal contacts on the battery compatible electrical parameters remain the same as in certain extent, be able to contain the market for mobile phone battery is currently chaotic.

Experts advise consumers to make full use original batteries, at least there is a problem can clearly identify the responsible party. As one of the shippers to buy, to the extent possible using the original charger, battery charger home can provide security.

Electrolyte can be used to find the “salt”   rechargeable laptop battery 

Experts predict that called ISP (FluoroSulfonylImide) of the TFSI anion is known to be a substitute material. This equipment and TFSI is different from the right and left with the non-CF3, but F. CF3 F ratio smaller, thus reducing the overall size. As mentioned above, small ions, the charge density will be larger,   dell inspiron 6400 battery easier to form crystals, but the magnitude of the size of ions, most of the viscosity the easier it is to reduce the effect best. The reason is that the ionic liquid through the ionic liquid itself, the performance of the viscous resistance of promoting the charge.

Above have been saying that the negative ions, in fact, positive ions are also a number of options. For example, you can use the name EMI (1-ethyl-3-methylimidazolium) substances. In the melting point is concerned, the use of salt TFSI -18 ℃, the use of salt as a ISP -12.9 ℃, the practical application there are no major differences. The viscosity at 25 ℃ different ISPs 32.6mPa * S fell 17.9mPa · s, reduced by about half. In addition, ISPs in the electrolyte,  sony vgp-bps10 battery  the ionic conductivity reflect the performance of 9.1mS/cm increased 16.5mS/cm, has raised almost doubled. These indicators, but not as an organic solvent widely used at present, but belong to the same level of organic solvent. In this way, ISPs should be applied to the battery.

In practice, the battery experiences of First Instance has achieved unexpected results: FSI and TFSI different, is not detrimental to the anode. The TFSI, there will be damage to the battery anode serious problems. And for reasons unknown.

Although still in the evaluation of the implementation stage, but not the anode corrosion, at least the performance of basic operation was confirmed. That any “rich” (Kansai University, Ishikawa), so that future performance will be constantly improved.

Make all the technology of solid coating particles, the battery

The second way to leave the organic solvent is the set of cells in the solid state. Original positive and negative is strong, then simply become a solid electrolyte can be. Osaka Prefecture University has studied the use of the class of sulphides all batteries, the solid electrolyte. For example, heating Li2S-P2S5 crystal glass after battery class, its conductivity at room temperature for more than 10-3S/cm reached. Has been achieved with the current use of the same level as the liquid electrolyte.  ibm fru 92p1141 battery In addition, the conductivity also increases in May are forecast to have reached a “seven times” the objective “dark horse”.

Osaka Prefecture University in April 2009, published jointly with the Toyota battery technology for all-solid coating particles. All semiconductor state thin film lithium battery type and accumulation-type. To use the car, the capacity is the decisive factor, if the University of Osaka Prefecture may improve the ability of the accumulation type launched a vigorous development. Specific approach of the negative active material, the cathode active material and solid electrolyte particles composed of three samples, respectively, according to the levels of bias of the law is gradually changing the mixing ratio, mixing and overlapping.

The difficulty lies in the method of grain contact resistance limit. This case, if the central government of the liquid electrolyte can be used “phenomenon” wet to ensure solid contact and liquid.   apple macbook 15 inch unibody While the differences between solids, micro-view of a single contact. In response, industry has been taken to put pressure on the deformation of tiny particles occurs as a means to increase the contact surface of the evolution of ideas.

Osaka Prefecture University, was chosen as a starting point in another direction, by the use of solid electrolyte thin film coating of electrode active material particles on the surface to reduce contact resistance. Electrode active material LiCoO2 used (cobalt oxide, lithium), the solid electrolyte Li2S used P2S5 types of material particles coated with PLD (filing of pulsed laser ablation) method.

PLD is one of the methods of thin film deposition. Objective is to use laser ablation, so the target material sputtered thin film formed on the bottom. Here, the practice is located in the above objective, located in the lower floor. Side of the floor vibrating, so the particle flux LiCoO2, hand, and the solid electrolyte particles are deposited on the surface to form a thin film. The particles are made from ALL-strong unit and the use of coated particles avoiding manufacturing time compared to a larger unit capacity. Confirmed the effectiveness of coated particles, so that all semiconductor battery state practice, a major breakthrough.

“Each year there are 100 million cell spent all that recycling is a big problem.”  laptop battery , laptop battery rechargeable  Days of power may be [4.13 0.98%] (00819.HK) Wang Zhi-kun head investor relations for battery electric bike is deeply concerned about environmental issues

Although electric bikes can achieve zero emission, but it is the “heart” – lead-acid recycling system battery is not perfect, the environment has been severely affected.

Recovery process confusing

Wang Zhi-kun told CBN reporter that current holdings of China for electric cars around 68 million, the annual growth rate of 20 million, it is estimated that in 2010 the total electric vehicles almost 90 million euros. Each vehicle equipped with 12 kg to 16 kg of batteries, the battery is only a year or two,  dell inspiron e1405 battery,dell inspiron e1505 battery,dell inspiron e1705 battery which country will produce 1.08 million tonnes per year to 144 million tons of waste lead-acid batteries .

Electric car is not only environmentally friendly, energy saving, but also a natural price advantage. Shanghai Xinzha recommendation of a sales person with electric cars the CBN said: “Every day, you pay only 1 dollar charge fee, will be able to manufacture electric cars walked 50 kilometers, spending on vehicle fuel is three – four times. ”

However, such a lead content of more than 50% of battery lead-acid by the state as “hazardous wastes”, sales of electric cars, maintenance, retail trade and the use of “how to recovery.

“Currently, the Shanghai region is about 2.5 million electric cars, recycled 2 million tons, but most recycling companies are small businesses do.” Operating in the manufacture of color wheel Shanghai lead second merger (hereinafter “flywheels Plant”) is responsible for Feng Guxiu man told reporters that these small retailers to waste batteries sold in Shandong, Jiangsu and Anhui, lead smelters to draw profits.

Another central inertia technical director said CBN journalist engaged in lead-acid battery waste collection, disposal, etc. of the company should have qualifications, small merchants,   hp pavilion dv9000 battery,hp pavilion zd7000 battery,hp pavilion zv5000 battery not the regular lead smelter has certainly not.

“In addition, a number of vendors selling process to reduce the transport weight of sulfuric acid directly down into urban and rural occupies a highly polluted environment.

In addition to the work of recovery is not in place, the decomposition of waste batteries internal to the fusion process is not standardized, seriously affect the environment. Scrap lead batteries, PVC housing, waste acids, etc., must all crushing, sorting. Flywheel Plant has purchased more than 10 million yuan of equipment to implement this step.

Decomposition of merger non-standard

Weak technical capacity of small foundries because of limited financial resources, using the artificial decomposition of lead and other contaminants can easily leak.

Smelting areas, the steam plant is regularly and want to lead dust, secondary smelting, but also contains large amounts of lead in the mud if buried, we would like to landfill a ton of fees landfill waste to pay 2300 yuan. ” Flywheel Plant technical director who said, “and started a small foundry of the night, will not do more to address issues of direct external, producing a large number of harmful gases and residues.”

Wang Zhi-kun said that due to annual growth rate of electric cars soon, the Company realized that the battery recycling is an important issue, day in office in June this year, compaq presario 2500 battery,compaq presario r3000 battery  has invested 200 million yuan building a particular type of recycling plant battery should be completed in 2012, will be capable of recycling 150,000 tons of batteries.

Shanghai climbing industry, company deputy general manager Shi Tao Hydrogen Energy, said that in Europe there is a requirement, manufacturers of batteries and electric vehicles have a responsibility to focus on recovery, so the European price of lead electric bicycle acid up to 400 euros to 1,000 euros, more than 2 to 4 times more expensive in China, “selling 1 dollar battery, companies must pay 2 yuan for the cost management the environment. ”

The Chinese government has also to do more to reduce waste batteries and various environmental challenges.

In 2007, the National Development and Reform Commission issued the “lead and zinc industry access” to further enhance the access threshold to prevent blind investment and construction of low-level redundancy, the State Environmental Protection Department has also directed the preparation of the series’ Waste and disposal of lead-contaminated battery acid specification control technology (draft) “and” Spent Lead-Acid Battery Standard Recycling Industry Cleaner Production (draft) “on the recycling of scrap batteries, sony pcga-bp71 battery,sony vgp-bps2 battery  and treatment of each session have strict requirements.

Shi Tao, said hazardous wastes – lead acid battery recycling in theory, should be a “closed loop” system, which is the cycle of the battery line is sellers – buyers – sellers (or depending on qualifications plant secondary lead) the future parties to a greater effort must be made.

New energy vehicles in China has brought a wave of enthusiasm,  laptop battery , rechargeable laptop battery  making mobile communications and mobile has had a huge convenience of audio-visual aspects of lithium batteries to become the competition’s most popular and one of the concerns. However, when more people living on the odometer, the battery life and even how to deal with waste batteries and so their brains, a very important fundamental problem seems to have been overlooked, is – simply secure?

March 1978, served in the pharmacy of the United States Exxon (engineer) invented Stanley • Weitinghanmu lithium, probably does not think the next 30 years the invention of science and technology to life in a huge change, and lithium, the lightest metal known the natural world has become more intimate and human together.

At that time, the sulfur compounds Weitinghanmu to the titanium anode, lithium metal as the anode in the first prototype of a global lithium battery.

It works by lithium-ion battery positive and negative cycle formed between the current movement to achieve load and discharge process. Therefore, lithium batteries, also known as lithium-ion batteries.

A few decades thanks to constant improvements to the anode and cathode materials, smaller and more energy density of lithium batteries, as well as lower prices were made, the advent of mobile phones, sony vgp-bps8 battery , sony vgp-bps9 battery , sony vgp-bps9a battery , sony vgp-bps9/b battery , sony vgp-bps9a/b battery   to further promote its miniaturization, lightweight, and later universal access to micro-electronic products, such as music players, today, is even regarded as a wave of strong electric cars inevitable choice.

Things, however, in recent years, mobile phones and the explosion of the music player’s battery is common, it seems that once again sounded the alarm – which brings convenience to people’s lives are not imaginary seem less secure. The relaxation of the manufacturer’s quality control it? R & D are elements of the battery changed? Or are they reserve power and neglects the importance of security?

A mobile phone battery contains lithium metal, lithium less than 5 g, a mini-electric cars more original, if rechargeable batteries 30kwh above, the battery contains lithium metal is about 50 kg or more,  dell inspiron 1420 battery,dell inspiron 1501 battery cell phone batteries will cause the explosion is still afraid of a group of mini-cars in case the battery if it happens, the consequences would be unthinkable.

China has held in lithium batteries installed in electric vehicles, parking in the garage during the night suddenly caught fire and the vehicle burned and the situation a few months ago, there was the phenomenon of spontaneous combustion of hybrid buses, but the discovery and elimination of too early, before major damage is not brewing. Obviously, the planning is the battery, the liability of the electric vehicle industry.

Indeed, the lithium there is an explosion of potential safety problems, many reasons to be broken, but apparently all the elements of its own can not avoid involvement.

Is usually a cathode of lithium battery, the anode, membrane, electrolyte, monomer packing five major components. At that time, Sony has developed the first commercial lithium batteries, the cathode of lithium compounds from lithium cobalt oxide is made, but because of cobalt are rare, then use more of manganese, iron, vanadium, hp 371785-001 battery,hp 372772-001 battery  nickel, etc., and synthetic polymer materials, and even the air electrode of the medium, different cathode materials, energy, security, operating voltage ranges.

Negative graphite and various hybrids, synthetic composite materials to play. Elements Graphite space, storage space for lithium-ion lattice.

Load, the cathode of lithium-ion transfer at the most negative of the box, where the negative electrode on the excessive accumulation of lithium-ion batteries to a certain limit, lithium-ion overflow, generating growth dendritic crystals and the spread of these crystals, the perforated diaphragm, so that positive and negative contacts, thus short-circuit occurs, this time short-circuit at the instant release a lot of heat, so easy to heat and combustion of the electrolyte boils, the final explosion, called “hot fail.” In addition, high temperature, piercing, ventilation chip connectivity, and vehicle collisions caused by compression of the battery became positive and negative short-circuit in case of causes of insufficient heat.

Thus, although there are some problems such as using lithium solid polymer electrolyte, which does not reduce the possibility of leakage of an explosion, but because of the lithium battery is the outside world by a chemical reaction internal electrical charge into chemical energy stored in the battery Similarly,  compaq presario 2100 battery chemical energy by chemical reaction in the production of electrical energy, so that the process will produce temperatures, once the temperature is too high, Hazard was also followed.

In addition, the lithium battery itself has a self-discharge characteristics is that the battery is not charging the outside world, the release conditions is in chemical reactions under varying degree of speed, battery-performance self-discharge rate is low, and vice versa, “self-discharge” rate is high. This internal chemical reaction on the table would make a music player, since the explosion took place in the OFF state.

Heat load and discharge the heat-absorbing characteristics of a lithium battery, but sometimes too fast charging will be the phenomenon of fever, because the chemical reaction is too late to chemical energy electric discharge the battery temperature is too late to chemical energy into electrical energy caused by the pricing if the management system generally safe, but there could be problems at the landfill.

Based on this principle, the discharge of the lithium battery  current should not be too large if the current is too large, too long May cause a chemical reaction and heat of the intense heat,toshiba pa3384u-1brs battery,toshiba pa3399u-1brs battery  and even caught fire and exploded.

In fact, advertising on the lithium battery can be a fast charge, rapid discharge of this concept is relatively lead-acid batteries, just a little faster, but if the charge and discharge of lithium across limits the danger could be hiding nearby.

As for lithium batteries in the end how appropriate discharge should be practical to decide, but for the vehicle driving cycle, the instantaneous high-current discharge are common, this is a test for lithium batteries.

Wages Now, load-discharge process is controllable, you can handle the manufacturing, metal powder, dust, and reduce the risk, but their chemical reactions inside the battery, but difficult to control.

From this, the process of lithium batteries in use, is a miniature “Volcano”, discarded after the lithium appears to be an “off”. After dismantling deleted as long as the body perplexed, ibm fru 92p1141 battery,ibm thinkpad r32 battery  the “five elements” is completed, the chemical reaction will not be interrupted, but the level drops, and thus the recycling of lithium batteries alone the seal as dangerous goods .

After analyzing the principle of lithium, resulting in a failure factors, R & D, manufacturers need to understand the lithium Angels & Demons double-sided, and the need to find a way to minimize security risks .

Performances such as lion, tiger stadium, the trainer must be animal control, the current lithium batteries, “animal” was not that people understand and master, applied to batteries of high capacity rechargeable and operating conditions of vehicles, poor working conditions should be cautious of the transaction.

Held recently in 2009 at the annual meeting of the China Society of Automotive Engineers, Society of Executive Vice President and General Secretary, said Fu-Yu Wu,  dell gd761 battery China is forming a strategic alliance of electric vehicles. Just this short time before, the China Association of Automobile Manufacturers also reported news for the implementation of the objectives defined at national level the development of new energy vehicles, SAIC, FAW, Dongfeng, Chang’an, Guangzhou Automobile, Beijing Automotive, Heavy Truck, Brilliance, Chery, JAC 10 automotive companies in North America have jointly established the “Electric Vehicle Industry Alliance”, and signed the “joint development of electric vehicles, the Platform of Action, aims to overcome all the energy saving and new energy vehicles in the industrialization of various difficulties encountered in the process.

The so-called alliance of the electric motor industry, including both pure electric, hybrid, fuel cell and other forms of new energy vehicles. It is understood that in “electric vehicles to develop a common platform for action”, signed, each electric utility vehicle project leader is also the leading group of industry,  rechargeable laptop battery  electric vehicles, electric vehicles set up working groups to carry out special research of electric vehicles, preparing plans of action, the establishment of Standard Electric Vehicle project working group to carry out joint development of electric vehicles, the standard preparation. The companies of the alliance on key elements, the main issues of developing the assembly joint research will form a unified planning. For the future development of the track, the track alliance has not yet unified, both may be part of the technical issues of common research, investment and production is also possible to their own research, sony vgp-bps9/b battery  the results of the WHO is good share other companies Zaiqu much as possible the search for efficiency, the joint development.

The last two years, the development of new energy vehicles in China has made great progress. Only the electric car is concerned, our country did not start late. If the overall level with the advanced international level that there is always a gap, but in some basic components, batteries, spare motor control, there are already some companies doing well, such as BYD, BAK companies. Currently, electric vehicles, industrial development of China’s problems are mainly embodied in three aspects: First, lack of product research and development capabilities;  hp 398876-001 battery second part the unstable product quality, consistency, poor 3 due to small scale and lead to production costs are higher. China still faces in the field of electric vehicle batteries, motors, control systems, lightweight technology, in areas such as the absence of the common core technology.

According to the “restructuring of the auto industry and the revitalization plan” propose development goals by 2011, China should put up 500 miles of pure electric plug into common type and hybrid energy sources hybrid and other new Qijuchanneng, car sales were energized by car sales total about 5%.

Faced with such an objective, which in recent years, the council runs through the basic technology has begun to break, for example, led by the Association of Chinese auto manufacturers, China’s production and research, and the Cross -industry, multidisciplinary coalition, while the strategic alliance of electric vehicles is also in training. 2009 The recently held China Automotive Industry Development International Forum on Science and Technology Minister Wan Gang said that the electric car as a new cycle of economic growth and achieving a breakthrough in the fundamental way to transport transformation of energy, has become the major countries of the world carmakers and common strategic choices,  China will continue to increase investment, the overwhelming support for electric vehicles as the representative of the new energy automotive R & D and market applications, will continue to support the common vehicle for technological upgrading, and exploit the potential of conventional cars, while saving energy to reduce emissions, accelerate the implementation power-processing engine technology strategy to further accelerate the industrial development of electric vehicles. The specific point of view, will the one hand, the core technology, key components,  toshiba pa3478u-1brs battery systems integration and infrastructure in an integrated approach on the implementation of national R & D programs, increase R & D investment from others, with small and medium cars and buses as a breakthrough, the implementation of incentive policies to further promote the industrialization of electric vehicles and marketing. At the same time will also actively promote the standardization of work, establish and improve standards of electric vehicles and regulations.

Carbon emissions from China after the United States
“China is now carbon emissions in the world, just behind the United States, countries, global warming is also increasing pressure on the issue,   dell latitude d505 battery so they will have greater use of fuels with low carbon. D ‘ According to Japanese statistics, the GPL to the same calorific value of emissions of carbon dioxide 15% less than diesel. ”
- National “863 Program” of the high energy saving and new energy vehicles special ad hoc expert Wang Binggang
Information Times News (see Zhang YQ) Guangzhou introduced LPG (liquefied petroleum gas) project on the environment caused by air pollution more? Recently, the South China University of Technology, laptop battery commissioned by a transport fuel made by a different relationship of bus exhaust emission test was after the media exposure has provoked strong reactions. Therefore, it was also recommended the promotion of electric vehicles yesterday, the reporter interviewed the national “863 Program” energy saving and new energy vehicles Wang Binggang experts hired by large projects, he said electric cars really more environmentally friendly, but not suitable for large-scale promotion.
Do not clean energy is a severe shortage of oil
Wangbing Gang said that China than any other country in the world to promote cleaner vehicles Alternative energy is more urgent, first, the growth rate of our vehicles is the world’s fastest, The car retains the current volume is 60 million, consumes about 120 million tons of gasoline and diesel, which represents the total annual consumption of China’s oil over a third by 2020, conservative estimates, the motorization of the country will be over 150 million, we do not promote clean vehicles energy alternative, it would be a serious shortage of oil supply, the second is the growth of vehicle,  hp hstnn-lb31 battery,hp pb992a battery environmental degradation caused by excessive pressure of major cities are attributable to air pollution from motor vehicles accounted for more than 60% contribution rate, if the promotion of clean energy can reduce emissions of pollutants, it is to reduce pollution of ‘air effect, thirdly, the CO2 (carbon dioxide) emission reduction requirements. China is now carbon emissions in the world after the United States, pressure on the issue of global warming are also bigger, so they will have greater use of fuels with low carbon. According to Japanese statistics, the GPL to the same calorific value of emissions of carbon dioxide 15% less than diesel.
Do not replace the energy system
Studies have shown that emissions of electric vehicles that LPG is good, greener, then, Guangzhou City Bus currently have the widespread introduction of electric vehicles? In this regard, Wang Binggang, said electric cars really more environmentally friendly, but large-scale development of electric cars, there are still problems: first, the price of the battery is relatively high, and therefore the high cost of electric cars, hybrid buses, with the same configuration more gas or fuel cars, the price is 2 to 3 times a car with pure electric gas configuration or even passenger cars fuel-price five times,  toshiba pa3191u-1bas battery which are difficult to support public transport companies or local governments; 2 also improved the reliability of the battery, its life expectancy is shorter, but also increased the share of costs ; bus power, the third as the emphasis on the use of car batteries, and safety issues should pay attention to current security problems still an experimental evaluation. Therefore, he suggested: first, Guangzhou, the current energy system must continue to improve the GPL, so that protection of the environment and the economy improved further, the second is the development direction of electric vehicles , electric vehicles should pay particular attention to technological development should strengthen its R & D and work in testing technology, the choice of routes, combined with the practice of Guangzhou, it is recommended that LPG and Li-ion battery hybrid bus trial, three of these energy systems existing LPG have been built and a concern over time as other new energy technologies is not yet mature cases do not easily scale other alternative energy systems, which will bring high costs and enormous risks. Development of the electric car is a gradual process, it is recommended Guangzhou active support of scientific experiments,  ibm thinkpad r32 battery  anxious to promote the development of electric vehicles.
