Tank and cell phone battery is empty: Pregnant freeze in car

Estenfeld - Empty tank, empty cell phone battery, empty wallet: A pregnant woman from Hesse had on the trip to her parents in three Hoechberg near Wuerzburg pitch. See what’s on it:

A pregnant woman is lying in her car in the cold.

It was not until she walked out of fuel and she remained in her car on the highway 19 are between Estenfeld and Würzburg. Refueling would not have been possible anyway, because the woman had no money. Shortly after she asked her friend via cell phone for help, was then also the phone battery is empty.

Because the pregnant woman nor her partner could not say at the last second that she is about ten miles from Wurzburg, gave the police after a call of a man on a quest. Two hours later, officials found the motorist shivering in her car. The police announced on Sunday Würzburg, lent the forces of the pregnant women a few bucks for a few gallons of gasoline. After the incident on Friday evening, the woman was finally able to still visit their parents.

Pitch is probably not the right word, rather, inability to master the little things of everyday life. As a father of two teenagers and a teacher I can see that many young people are less and less “get to the series, but demand for more and more understanding. You will find it increasingly normal to miss important appointments, forget important documents that do not meet accepted tasks. Irresponsibility is the rule, while it falls out of fashion, such tendencies call a spade! Anyone who does that came out as old-fashioned, as old-fashioned! Hey Age, stay loose!

I think that the general provision of the prosperity drugs, such as “mobile phone”, “navigation systems”, etc. .. define as a lot has to do with it: you need not make any more precise understandings ( “I am now at the XY place where art thou?”) you must not organize / ( “I stand here in front of the shelf, honey, look but please if there is time yogurt in the fridge “)
Well, when the battery from the phone once it is empty, because you like someone who goes solely by the Navi and he drops out or he finds it no longer an
Blessed is he who throws home BEFORE it moves off vielliecht still take a look at the route, especially if he does not know … or just take a look at the fuel gauge throws and has even a sense of how far is the distance around.

Sony batteries Pandora programs ineffective structural changes

Some people overseas have found that the Sony PSP-110 battery (the old version of the original PSP battery), is now writing brushes can use Pandora battery procedures. Amazon recently departed from battery manufacturing process was purchased Magic Battery (Pandora’s process IE) an error when the system will be soon. Still, there is EEPROM can not work.

Old and new batteries before the battery is the difference between China Khan (the root), from Amazon for a battery of Japanese origins of this piece is purchased.

In fact, it is not surprising that one’s worth, according to Sony’s common usage, battery new battery after a break is expected to introduce to resist was cracked. Finally, using magic PSP battery system, regardless of what kind of an older version can be easily shield. In addition, the market has spread so that the shield (the last year, sales of the original battery PSP batteries can randomly be used in making the magic battery).

Alone inside a button to replace watch battery, even earning an average of 1,500 yuan per month, which may cause not very confident, but it is indeed a true story.

5 years ago, from Chaohu, Anhui Province, a 20-year-old girl, in my district where placed in front of a button to replace watch batteries stalls next to also shore up a billboard that reads, “Please be assured of : The cabinet sold by certain licensing button batteries, purchased from approved sources to authentic, and each pill is approved purchase cost 5 yuan, plus a variety of fees to be paid, so the sale price set at 10 yuan. Welcome to presence of the cabinet to replace the battery, from the date of replacement, if the battery less than two years, I unconditionally to 10 times the original price to be compensation. “inducing effect of such advertising, this rapidly booming business pitch up. At the same time, everyone’s commitment to this girl is also very appreciated.

Well, this girl is how to fulfill its authoritative, it? Recently, I witnessed the unusual move of her: She watches every customer to replace a button battery, it will pocket out of a China brand pencil case back to the inner walls of the table to sign the name of his own mini - When will the day as well as a few minutes, and then tighten the table cover, calibration time Didao customer hands, and smiled and said: “You watch where have my mark, under normal circumstances, this grain button battery, if less than 2 year, please come to me, I will compensate your loss, believe me. “When the customer took delivery to 10 dollars later, she re-invoicing.

“Proof of the pudding, something a long time see the people.” Sure enough, when the customers come back the next time when the replacement button batteries, unscrew a case back look at the dates, are more than two years, and some have even gone almost 3 years.

By contrast, some booths and even some stores to customers the same button to replace the battery, even though the price is relatively cheaper, but it can not be “launched” to two years, its authentic or not, find it difficult to distinguish. Eat a cutting wisdom, so more and more customers to vote in order to praise the girl’s attention, have let the girl inside the button to replace watch batteries. As a result, their business several times higher than others naturally. It is learned that since four years ago, this girl more than 10 pieces a day to replace watch battery button to remove a variety of costs, guaranteed profits, 50 yuan is not a problem.

Said is now difficult to do business, put it bluntly, it’s difficult to be in what state of mind and know-how to do that in good faith under the premise of how to use one’s opponent to tap the business, the details of the door, this might be the girl given the greatest inspiration.

Hybrid Intelligent Charger come Almighty Chong

Recently, an “all red” hybrid smart charger Industrial dslr battery grip Co., Ltd. in Shenzhen, the base earnings come out. This from the company’s “international Tong” brand successfully developed both to Ni-MH battery charger charging, is able to alkaline batteries, rewritten non-rechargeable alkaline battery technology gaps, but also solve the waste battery recycling and re-utilization problems.

The basic design be the same: the battery into a bottleneck in the development of electronic devices

Most consumers are now aware that engineers were well aware of for many years a problem: the battery can not keep up the development of other electronic devices. And, unfortunately, this situation not only can not be improved in the short term, there is likely to get worse before improving.

With the new mobile phones, music players, or notebook computers, most people would not put it down to it, wait for them to hold all day to play, provided that the battery Nengcheng put the situation. Thanks to ever-shrinking size of computer chips, consumer electronics industry for products to add more features, but this is far more than the battery industry can adapt to speed.

The famous Moore’s Law makes the computer chip capacity will double every two years or so. In the United States Menlo Park, California, Stanford Research Institute International (SRI International) chaired the study of physics, said Lawrence Dubois, battery capacity increase to almost 10% per annum. He said that improvements in battery performance is often gradual and orderly progress, these advances are very flat and even, such as design thinner and lighter battery casing, thereby saving space.

In this case, the equipment manufacturers to improve every point on the battery are extremely great importance, not surprising. “Even if only 20% increase in energy efficiency, can allow mobile phones thinner or larger and brighter screen.” Samsung’s vice president for mobile business Mouz Bo Kaen, said: “It will bring more opportunities. “

Shi Zhengrong: Solar cell prices will drop by half within a decade

Energy’s richest man, Zhengrong Shi, opened in Shanghai, “China International Industry Fair” on. He said a large number of Chinese companies flocking into the solar photovoltaic industry, the upstream product to make the polysilicon industry, strong demand, prices rise, but the homogenization of the result of competition would be to have shrunk by half a decade later the price of silicon. At the same time, he believed that the real competitor is the solar thermal power generation and other traditional industries, rather than the same industry with the ever-escalating price war.

Recently in Europe, a study reports that by mid-century solar power will account for 30% of the entire energy supply, while the end of this century the ratio will rise to 70%. Zhengrong Shi said: “The solar industry is the future of energy development.” However, when checked on this diagram, he was a bit worried frown and said: “This figure indicates that although the demand for solar energy grew by 5 years, 37%, but a few Chinese solar companies only have as many as 400-500. everyone has pushed up upstream polysilicon and other raw material prices. ”

Over the past 3 to 5 years, polysilicon prices rose by 165%, “and this price rise in China, reaching 200%. This is very normal.” Shi said that the second and third quarters of 2006, China’s solar cell has reached its highest price, that is, one-watt solar cells 4 to 5 dollars. The fourth quarter, there were obvious signs of decline, down 5% to 10%. “Next year, this figure will fall by 5% to 10%.”

Suntech Power Co., Ltd Sales Director, Mr Yip told the “First Financial Daily” to the 2016 one watt of solar cells will sell for under 2 dollars, when the market will change significantly.

The quality of the

In a growing number of products cases, ensure that the new energy products, quality is very important. Shi Zhengrong, said that if the price of solar cells down to 2 dollars or 1.5 U.S. dollars of the time, then it will be close to the basic cost of thermal power generation, then a large number of expansion is also necessary.

Many companies are suddenly in an area can be understood, is also normal, but not all companies are suitable for coming, Shi Zhengrong that the different energy products and daily consumer goods, which may be the better quality and more expensive prices, but only got to have good energy products the quality, but also a suitable price. “You finally found a customer, but this product can not maintain long-term life span, the price even lower had lost its credibility.”

Not long ago, the world’s leading companies an accident that occurred at BP, the company ignored the quality of testing, a sudden combustion-related products. “If your product can not have 30 years of quality guarantee period, a 100-year life, I advise you not to do the battery.” Shi said.

Polysilicon battery is a long industrial chain. Start with a general refine silicon in high purity polysilicon, and then through the cutting processing, and then create a package, good battery piece. At present, because the refining equipment and technology is not mature, so this part of the Chinese companies are less capable in general for the international monopoly of a few enterprises.

The control of silicon ingots and cutting links, as well as film and battery components, battery manufacturing, China have become in the world.

In order to end products can be declining price of the battery must be carried out technological innovation and transformation equipment. And technological innovation on the one hand, is the use of thin-film batteries, that is, the original battery replaced with 300-micron thinner battery, can generally reach 2 to 3 microns, so that not only cost savings, also be applied to a wider range of industries . Shi Zhengrong, said: “Suppose the mature thin-film batteries with the existing conversion rate of polycrystalline silicon cells, it means more than 15%, then the future market will be dominated by thin-film batteries.”

Battery protection chip: Semiconductor makers compete for the hot spot

Recently, Cirrus Logic Inc. announced the acquisition of local IC design company, Caretta, thereby extending their reach to the field of power protection IC. And traditional IC manufacturers, such as NS, TI, Maxim, and other long lithium battery just a few years ago began to develop, on the set of the Battery Protection IC research and development.

With the portable market continues to heat up, lithium-ion battery market has also followed suit, giving rise caused by the increasing number of battery protection IC vendor’s attention.

The market of several billions of dollars a year

Cirrus Logic for audio and industrial applications and embedded mixed-signal IC products is known for the industry. The Cirrus Logic acquisition, Caretta is a Shanghai-based fabless IC design company, mainly for single-cell lithium-ion battery battery protection IC market development.

As the environmental requirements and portable video cameras, notebook computers and multimedia equipment, such as the popularity of rechargeable batteries are widely used, together with today’s rechargeable batteries being environmentally friendly, thin, small energy, high density, direction, makes rechargeable batteries, especially high-capacity lithium battery market share is growing.

Data show that in 2003 -2006 the global lithium-ion battery production scale compound annual growth rate of 23.2%, sales revenue compound annual growth rate of 12.25%; 2007 -2,010 years, lithium-ion battery industry will enter a relatively stable growth stage, is expected to produce the size of compound growth rate of 9.85%, sales compound annual growth rate of 5.85%. Mobile phone market as an example, according to iSuppli forecasts and other authoritative bodies in 2006, the global mobile phone shipments reached 950 million more than in 2007 to more than one billion. China’s mobile phone industry and market development faster than the global level, in 2006 domestic production more than 400 million handsets, accounting for 40% global share. According to Sino Market’s survey and projected 2006 sales of the domestic market is expected to total 120 million mobile phones. To each cell phone battery with a piece of the calculation, we can easily calculate the next year or two the market size of mobile phone batteries. The other portable consumer electronics products to the demand for rechargeable batteries is also increasing.

According to industry experts, the rechargeable batteries during use, over-charge, over discharge and over-current will affect the battery life and performance, for the safe design, battery batteries, especially lithium-ion batteries to be installed to protect plate, in order to to prevent overcharge, over discharge and short circuit caused by combustion, explosion and other dangers. This safety protection board is a dedicated IC and several external components form. Rechargeable battery protection IC loop through the protection of effective monitoring and to prevent damage to the battery produces.

Tianjin Nanda strong core technical director Zhang Xing In an interview with “China Electronics News” interview, said, as each lithium-ion batteries required to install a battery protection IC, so mobile phones, laptops and electric bicycles, and other markets, driven by Battery Protection IC market will grow continuously, the current global battery protection IC has been billions of dollars a year market.

Public companies actively involved in competition

For a certain in analog IC technology-based companies in terms of, intervention into this area is not a difficult task. Although many large international companies, such as TI, Maxim and others have some power solutions, but each company should focus on different fields, therefore, faced with the huge market, as long as identify the entry point, the opportunity is always there.

Cirrus Logic President and CEO David D. French, said: “Cirrus Logic’s core products, we benefited from the success of analog and mixed-signal expertise. From this perspective, the acquisition will help us, Caretta the mixed-signal knowledge extended to areas of power management. In addition, this acquisition will enhance our local Chinese engineers and customer support teams, to Cirrus Logic’s long-term development in the Chinese market for long-term assistance. Acquiring Caretta expands Cirrus Logic in the analog integrated circuit aspects of the field of professional competence and diversity. “in 2005, Cirrus Logic out of digital video SoC market, focusing on the company’s core areas of strength and development for audio and industrial applications and embedded mixed-signal IC products. The acquisition by virtue of their accumulation in mixed-signal IC technology, a smooth transition to the analog IC the most important part - the power management area, to strengthen their own competitiveness.

Maxim Market Leader told the “China Electronics News” reporter, Maxim had several years ago to develop lithium-ion battery protection IC, and that the battery management products as an important part of product line and remains subject to the company’s emphasis on constant there are new products coming to market.

TI has also continued to strengthen protection of lithium battery charger IC product performance, they introduced a product bq24060, enhanced thermal fold-back regulation and low dropout power management features.

Strong core of Tianjin Nanda-hing, said Zhang, the original Tianjin Nanda strong core machine just for large foreign firms to provide design services, but see how power management IC market outlook, they also developed a corresponding battery protection products, with a view to enter the domestic market.

So many have not previously been involved in the design of power management IC market, are turning to the field, combined with the traditional power management IC vendors intensive, I believe it will be more intense competition in the market.

The truth about notebook battery

It’s one of the most important and least understood parts of your notebook—and it provokes so many unanswered questions. Why do laptop batteries gradually lose their ability to hold a charge? Why does it takes longer for a charging notebook to go from 80 to 100 percent charge than it does to go from zero to 80 percent? What’s the difference between a three-cell and a six-cell battery? Rather than shrug our shoulders for another day, we demanded answers from two experts, Matt Kohut, worldwide competitive analyst at Lenovo; and John Wozniak, Ph.D. distinguished technologist at HP.

LAPTOP: At what point during Presario 2100 battery life cycle does a typical notebook battery last longest?

Kohut: The industry average is about 30 percent degradation per year. You’ll probably start to notice after about six months.

John Wozniak: Batteries tend to fade pretty quickly over the first 10 or 20 cycles, and then capacity levels off.

How long does a typical notebook battery last?

Kohut: Roughly, 350 charge cycles. A cycle is cumulative use that reaches 70 percent degradation, or seven times when 90 percent of the battery capacity was used.

What causes a battery to lose capacity over time?

Wozniak: Think of a Presario 2500 battery as having pores, where the electrons flow back and forth between the cathode and the anode. When those pores get clogged, you can’t move the electrons as efficiently anymore. Then the lithium gets bound up on one side or the other, and it no longer contributes to the movement of electrons. It gets backed up.

Do you need to build up a battery memory, or condition it, to get the best performance?

Kohut: This was true in the lithium-metal hydride days, however, with a standard lithium-ion battery, you just need to make sure you charge it fully. Most batteries ship from the manufacturers with an 80 percent charge.

Conditioning, meaning draining the battery to zero and then charging HP ZE4400 battery fully while Windows monitors it, resets the curve. It doesn’t prolong the battery’s life, but it improves accuracy [of the battery monitor]. Over time, the accuracy drifts in the Windows program that measures battery life. That is why it can say that you suddenly went from 80 to 20 percent in five minutes.

How much can you trust the charge status that Windows gives you?

Kohut: If the battery reports full, Windows says it is full. Windows periodically checks the battery, but it is more of a thumbs-up/thumbs-down than a real assessment. Windows is crude; trust it if it’s full, trust it if it’s empty. But know that it doesn’t have the communication to know that the Pavilion DV2000 battery degrades over time. We recommend the Lenovo Power Manager, because it has a lot more smarts. It knows the status of each individual cell, whether it’s balanced, imbalanced, charging, not charging, etc.

John Wozniak: If the BIOS is written correctly, Windows is really accurate; within 1 to 2 percent. The problem is how often it updates.

When charging a notebook, why does the last 5 to 10 Percent take longer than the first 85 to 90 percent?

Kohut: If the EVO N400C battery is low, we will charge it at a faster rate. But when the battery fills up, we back off, because it’s the last bit of charging that causes the issues to form. Other vendors that do rapid charge still back off around the last 10 percent. Dell, for example, does fast charge, pedal to the metal, from zero to 80 percent. Then backs off and coasts into the finish line. Lenovo starts fast, but backs off more and more through the entire charge. This allows for a more even rate of charge. It takes longer overall, but it helps the battery’s longevity.

Some notebooks won’t start charging unless the battery is below a certain level, SAY, 95 percent. Why is that?

Kohut: Charging it to 100 percent every time adds cycles that cause the inspiron 1525 battery to wear out faster. In the typical office situation, you’re plugged in 100 percent all day. Then you take it home, and plug it in again, after losing maybe only 2 percent. If you charge to 100 percent again, you start adding cycles that wear out the battery because you’re initiating a full charge cycle. The thought behind our process is that unless the battery gets below a certain percentage, don’t put it through the stress of charging.

How important is the number of cells in determining battery capacity?

Kohut: The three-, six, nine-celled battery is shorthand for explaining how much laptop battery life a machine has, but watt-hours hours determine capacity. The average consumer has no clue that a nine-cell battery has around 84-watt-hours of power, they just know it’s a nine-cell. One of Lenovo’s competitor’s has two six-cell batteries—a 53-watt-hour and a 47-watt-hour. The second doesn’t deliver the same capacity. To really understand how much power a battery will hold, you need to look at the watt-hours.

Some vendors are advertising two- or three-cell batteries that claim a longer life than six-cell models. Is that possible?

Kohut: There is a fine line. Ibook G3 Battery VGP-BPS2C capacity has gone up in the past few years by making the cells more energy-dense. There used to be 2 amp hour (Ah) cells, but now cells go up to 2.9 amps. If you can control the higher concentration of energy in the smaller space, it’s not a problem. But sometimes this results in violent reactions such as overheating and over-charging. [If a vendor claims its battery lasts a long time with fewer cells,] you want to ask how many watt-hours the pack holds, and about the kind of cells (2.6, 2.9 Ah, etc.).

Should consumers trust third-party batteries?

Kohut: We’ll warranty our own batteries, but if you put a third-party battery in, you void the warranty. That’s because there are good Powerbook G4 battery manufacturers and there are bad ones. Some of the good ones are Panasonic, Sanyo, and Sony. A less reputable company will buy whatever is cheapest, and just drop it in there. The reason a lot of the battery incidents occur in this industry is because of quality control.

We always say that you are taking [the life of your notebook] into your own hands when you buy a third-party battery pack. Yes, you are saving some money up-front but you don’t have the backing of the company behind it.
