Producer: bulge is a common phenomenon

After running manufacturer sales personnel of the Ministry told reporters that the torrential rains and service charge the battery is discharged, part of the heat battery, battery a little flower, “while not affecting normal use, there is no threat to security is. Consumers can be sure that use.

12,315 Foshan: Flowers should return

Bureau of Trade and Industry accepted Foshan to 12.315 advisers, said that the battery warranty, there swelling, repair of consumer request the business plan, if can not recover, etc. If the place should be.

“For general use in battery case as an excuse for companies” can not be replaced is unfair. If the player does not change, the Consumer specified department or vendor specific sections of the test report, the agency requires companies to Can. If the company does not provide, consumer complaints from 12.315.

Reminder: do not use universal charger

Experts say that mobile phone battery is commonly used in lithium batteries, the battery exploded, there’s actually three: First, for battery reasons. Since internal flaws battery, battery charge batteries discharge explosion case but the other surcharges are. A certain temperature, humidity and poor contact, etc. or lithium battery in the atmosphere, significant transient discharge currents, leading to spontaneous combustion or explosion, the third small, is likely to be low.

, One particular brand of cell phone service personnel tell Foshan, call for using “balls to prevent mobile phone battery option” to change, we should try to choose well brand products, free go mobile phone model in Milan prosecutor who must choose, do not meet the present, based on non - uniform standards under the battery, charger not universal. In use, the battery will be placed in high temperature environment. There used batteries is damaged or inflamed, In addition, as possible, as some now call a long time Take the phone, you must use a headset. Also, it not the best phone on his chest.

Master Control Unit design and implementation: Master Control Unit is microcontroller PIC16F873 and keyboard controller chip ZLG7289A composition. The main task is responsible for communicating with the different costs today, and the processing of user input and LCD display information. The keyboard controller chip in here for six buttons and 12 LED control. ZLG7289A with a microcontroller through the SPI bus between the two-way communication. Main control unit charge per check every time unit, to obtain information about the current charging unit, as there is no battery, battery properties, the battery voltage. Followed by the LCD module to the user.

Design and Implementation of Charging Unit, LTC4002 Li-Ion Battery Charge Controller: LTC4002 is a high efficiency switching independent lithium-ion battery controller. The manager has two versions of 4.2V and 8.4V. LTC4002-8, 4 has a 500kHz switching frequency, is a high efficiency current mode PWM controller. This is an external P-channel MOSFET drives, it can provide 4A of current costs, while the efficiency can be as high as 90%. Output voltage is set at 8.4V, the final drive voltage with 1% accuracy, while the 5% charge accuracy. Furthermore, the handset can be 9V ~ 22V wide variety of wall adapter to run. In comparison with the hysteretic topology chargers, LTC4002-8, 4 of the fast operating frequency and current mode architecture to enable the use of small capacitors and inductor / capacitor combinations.

Lithium-ion / Ni-Cd battery loading unit of the overall design of the dual use: LTC4002 the face of an analysis of the past can see, the chip is for the lithium-ion battery controller, the nickel-cadmium batteries need to address the following issues: First, LTC4002 to monitor the battery voltage to ensure that the battery voltage does not exceed 8.4V. But for nickel-cadmium battery pack, charging cut-off voltages up to 9.2V. Secondly, the nickel-cadmium batteries come to an end, the need for batteries in the normal current 30% and 10% of the droplet charge. Thus, the second problem to be solved is how the size of the constant current charge current control. Moreover, nickel-cadmium batteries to charge pulse mode. Namely, 1s cycle, 95% of the time to 1% of the time charged the remaining time for the output is not paid leave. Finally, the court that a lithium-ion battery battery or nickel-cadmium batteries, lithium-ion batteries because if the miscarriage of justice for the nickel-cadmium batteries, will charge voltage higher than 8.4V, this lithium-ion batteries is very dangerous, but will nickel-cadmium batteries for lithium-ion battery miscarriage of justice, it may lead to insufficient battery loading. Therefore, we must ensure that a very low false positive rate.

The LTC4002 works partially based on the design of both the lithium-ion battery constant current - constant voltage load, they can nickel-cadmium battery pulse charging system. Charging the unit’s overall functional block diagram shown in Figure 2. Among them, signal-conditioning circuitry to both charger for 8.4V lithium battery load, but also may be 9.2V Ni-Cd battery load, but also play a role in controlling the size of the load current. LTC4002 use of micro-manager control work state, with the redundancy circuit that nickel-cadmium battery charger can be off loaded from pols run. Micro-controller through a certain communication protocols (HDQ16) and intelligent battery communication, to determine their capacity, the chemical nature of the key parameters.

The battery will not explode

While the issue of lithium battery technology, there is no clear explanation lithium battery manufacturers, but it is clear that they also lithium-battery manufacturing technology and standards to improve.

laptop battery

Last year’s laptop battery recall incident, Apple, Dell, HP, IBM Lenovo, and several notebook manufacturers have already begun to consult together to create new standards for lithium battery development.

Before that, the field of mobile phone battery in a notebook, and there are various standards such as IEEE (Institute of Electrical and Electronic Engineers) in 1625 and 1725 laptop battery standard cell phone battery standard recognition rate is high. Dell’s recall after the incident, the IEEE announced that he would continue to review the standard laptop battery to change plans at the end of this year at the IEEE 1625 standard will be changed.

In the phone lithium battery recall incident, it was reported that Japan Electronics and Information Technology Industries Association, the battery business will be information and communication networking industry association, and video equipment operated for a few days ago, began working at work in the establishment of technical standards for the safe use of Lithium batteries. According to reports, the industry associations involved in notebook computers, cellphones and digital cameras and many other industries.

Changes are synchronized with the standard Lithium-Ion battery is that more and more new cells are developed.

Last year’s laptop battery recall after the incident, located in California, Zinc Matrix Power Inc., once activated, the enthusiasm of the outside world since the company invented a mixture of silver and zinc “will not explode the battery, and battery use of time longer than lithium. CNET technology news from the network, say 1999-2006, the company has received approximately 32 million dollars in venture capital investment. But because the company can resolve the zinc battery loading problems, which will not achieve short-term large-scale commercial application be.

Another type of an attempt to replace the thin-film lithium batteries are also attracted outside attention. It is clear that there are more thin-film batteries Lithium batteries are safer, and the number of repeated charge and discharge to thousands of times. Production of thin-film batteries Infinite Power Solutions Inc. announced that it is more than 34.7 million U.S. dollars investment company’s investment, it will enable the volume production in 2007, thin-film batteries are received.

Furthermore, as fuel cells and other types of battery are also being developed.

Fuel electric cars

Mercedes-Benz’s first hybrid electric car will use the Johnson Controls Battery - dell FK890 and dell GK479.

2009 Mercedes-Benz plans to launch a fuel and electric hybrid S-class sedan, and strive to become the first one to market devaluation use of lithium-ion dell RN873 battery hybrid vehicle manufacturers.

Earlier this week the opening of the Frankfurt International Motor Show, Mercedes-Benz an executive said the batteries would be Johnson - Saft (Johnson Controls-Saft) available. This joint venture last year by the United States, an automotive professional interior / battery suppliers, and a dell inspiron 1150 battery manufacturer in France joint venture. The enterprise plans to build a new plant for the production of lithium-ion batteries to customers in Europe. The plant is located in France’s Nicolas (Nersac). Johnson Controls - Saft has invested 15 million euros for this; new factory production lines will be operational in 2008.

Saft Management Committee Chairman John. Hill (John Searle), said: “I am pleased to see that Saft and Johnson Controls technology combined with each other to create this and other important levels of the first project.”

Mercedes, senior managers mentioned that the dell inspiron 1501 battery company’s 2009 models S 400 cars will be equipped with a medium-hybrid power system, the system’s electric motors can also act as a starter-generator role. But they did not talk about this car when it will enter the U.S. market.

Although the S 400 used car battery, its power supply than full-hybrid vehicle or a plug-in hybrid car batteries used in batteries, but Johnson Controls - Saft CEO Mary. An. Wright (Mary Ann Wright) said engineers were still full-hybrid vehicle in accordance with the test battery used by the stringent standards to test the battery. “We have our confidence in the design and safety measures,” Ms. Wright is responsible for oversight and management of battery design and development engineers. She said that the design of dell inspiron 1520 battery , dell inspiron 1521 battery life as long as the life of the car.

Said the manager of a Mercedes, S 400 hybrid sedan from 0 miles / h speed to 60 mile / h in just 7.3 seconds left. He also said that S 400 will become the world’s most fuel-efficient luxury cars. Ms. Wright said: “We are very pleased to participate in this project dell inspiron 1525 battery, Daimler, and we work together to develop an advanced hybrid vehicle systems.”

Lithium-ion batteries is expected to replace the current hybrid vehicles use nickel-metal hydride batteries.

Toyota Motor Corporation had plans to use powerful high-tech batteries to equip its next-generation cars and the company’s other hybrid vehicles dell inspiron 1526 battery. But the company’s one official recently claimed that their batteries until 2010 or 2011 in order to be ready.

Hunan Hengchang 1 # lead sales lead the industry dynamics dell inspiron 1545 battery.

Hengchang lead the industry today, # 1 quote for the lead in the mainstream of 23.15 thousand yuan / ton. The company said the current market situation has improved, more positive downstream receiving goods, transactions can still be. Company believes that the recent rise in lead prices sony VGP-BPS13 , sony VGP-BPS13EA should be moderate.

The zinc supply and demand

The world’s refined zinc supply and demand gap gradually disappear with Laptop battery

International Lead and fujitsu fpcbp136 Zinc Study Group (ILZSG) released data show that in 2007 the world from January to October City, a shortage of 51,000 tons of zinc same period last year gap in the market of 44 million tonnes, an annual supply gap over the past three years are 30 million tons. In November 2007, December refined zinc consumption in winter is low season, while production continued to show inertial growth, it is expected that the global refined zinc production in 2007 will reach 11.3 million tons, compared with 2006, an increase of 7.4%; consumption will reach 11.25 million tons, up by growth of 1.9%, the global supply and demand balance in 2007, basically.

However, due to the supply fujitsu fpcbp136ap of high-speed growth will continue, and far higher than the consumption growth rate, since 2008 the world will be a shortage of refined zinc supply and demand patterns shift to a surplus. A substantial increase in world production of zinc concentrate zinc market trends led to the most fundamental reason for the surplus.

From the author collected in 2007 related to expansion of production capacity or re-start mining production statistics show that in 2008 the world’s zinc concentrate production will increase by more than 900 thousand tons fujitsu lifebook t4010 battery, which will enable refined zinc production in 2008 is likely to remain more than 7% growth rate is expected in 2008 refined zinc production will be more than 12 million tons.

The current consumption of refined zinc of around 4.5% growth rate calculations, we believe that in 2008 the amount of refined zinc surplus will reach 30 million tons. The UBS recently released a report that since 2007 there are 15 new projects put into operation in 2008, global zinc supplies will grow 11%, the market will 出现 60 fujitsu lifebook t4020 battery million tons of surplus.

Rebound in nickel prices

Rebound in nickel prices

Recently, such as DJ-AIG Commodity dslr battery grip Index adjustment of weights, driven by flow of capital to promote the sharp rebound in base metals started. However, the U.S. manufacturing sector weakness as well as the unemployment rate to 5% showed the risk of a recession increased last week, the Fed said it would take active measures to boost the economy, Bernanke’s speech to enhance the market this month, the Federal Reserve’s monetary policy meeting by 50 basis points rate cut expectations. Increase in market uncertainty makes base metals price movements rather repeatedly, while the short term a weaker dollar will remain supported by the basic metal prices to a certain extent.

Lead: Lead prices since the beginning of the performance is canon bg-e2n vertical-grip relatively stable, LME lead prices up to 2715 U.S. dollars / ton, the lowest 2502.5 U.S. dollars / ton, last Friday to close at 2615 U.S. dollars / ton. Lead prices fell due to losses caused by a larger, 12-months of about 600,000 tons in Yunnan region to stop production capacity. Spot due to smelters to reduce procurement lead-processing costs (TC) significant increase in Chinese imports of lead concentrates spot TC surged to 350 U.S. dollars / ton. It was also reported that residents and the health minister in Western Australia under the Magellan mine against Ivernia (accounting for 3% of global supply) from the Fremantle port of shipment of lead concentrates. Lead supply remains tight, the International Lead and Zinc Research Organization (ILZSG) 10 months of data showed that a shortage of 28,000 tons, the late lead canon bg-e3 vertical-grip prices rebound power still exist.

Tin: LME tin price of the recent overall trend showed a narrow range of finishing, the highest on January 3 touch 16,862.5 U.S. dollars / ton, followed by oscillating drop last Friday to close at 16,267.5 U.S. dollars / ton. Both China and Indonesia will be restricted the export of tin this year, China’s export quota of 37,000 tons, down from last year to 33.3 thousand tons, from January onwards non-alloy of tin, tin waste and scrap the export tax rate is raised to 10% from 0, coupled with tin concentrates 20% of the export tariffs, thereby also showed the country to further restrict the output of the determination of tin resources canon bg-e5 vertical-grip. Due to limited supply of tin consumption to grow steadily, the late tin price performance will be more firm.

Nickel: As the DJ-AIG Commodity Index increased weight of nickel, buying the active involvement of promoting a sustained rebound in nickel prices in the last red to 30.85 thousand U.S. dollars / ton in the vicinity suffered a strong sell-off last Friday to close at 28,525 U.S. dollars / ton. Consumption of nickel is still no obvious improvement, the International Stainless Steel Forum (ISSF) released preliminary data show that stainless steel production in 2007 had a clear downward trend in the third quarter stainless steel production fell 16.6% to 5.9 million tons. LME nickel stocks are still as high as 47,544 tons, while the cancellation of warrants is only 1860 tons, indicating that stocks may continue to rise later. As the commodity index weight adjustment fujitsu fpcbp205ap and fujitsu fpcbp205 will be the end of Monday, post-nickel prices will return to the fundamentals of supply and demand-led, demand weakness in nickel prices would rise weakness is expected short-term nickel prices will continue to repeated oscillations.
