First, avoid using unnecessary zoom operation, if it is to zoom, it is recommended to move the camera position to get the same zoom effect. Second is to avoid frequent use of flash, flash is a big power, unless forced to do the best to use. What is best to use when adjusting the viewfinder image, but do not use the LCD screen.
When the digital camera battery for some time, but also the necessary clean the battery. Many people may focus only on digital camera lens and body clean, but never thought the battery should be cleaned. To avoid power loss problems, be sure to keep the battery and battery contact points at both ends of the internal cleaner lid.

Digital camera battery charge in the process of the correct method of charging to pay attention. Best to use the original digital camera battery charger, which will help extend battery life. The charging time depends on the charger and battery, and the use of voltage stability of the other factors. If this is the first use of the battery (or batteries for months not used), to remember, lithium battery charging time must be more than 6 hours, Ni-MH battery must be more than 14 hours, otherwise, will be shorter battery life .

If there is residual power digital camera battery, try not to repeat the charge to ensure battery life. If you are a nickel-cadmium battery, a charge will only stop charging, and then recharge it, doing so is the battery can not be filled. This is what they call the “memory effect”, this effect would reduce the total capacity of the battery and the use of time. Over time, less and less stored charge, the battery will also use the faster and faster.

If you plan a long time do not use digital camera, digital camera must be from the digital camera or battery charger taken out, and it is completely discharged, and then stored in a dry, cool environment, and the battery with metal objects in general stored together. For a long time stored in the digital camera battery or charger may leak and damage other.

Obama is scheduled to fly to Michigan the same day Holland city to participate in ground-breaking ceremony of a battery factory.

The facility will be GM’s Chevrolet “Volt” series and the Ford Motor Company, “Focus” series hybrid battery production.

The federal government expects that by 2011, this project can promote plug-in hybrid electric vehicle battery to increase annual output to 50,000 to reach 500,000 by 2014.

White House spokesman Robert? Gibbs 14, said: “We intend to produce these products in the U.S. (electric vehicles and battery), we need to create jobs for Americans.”

Although there are many domestic enterprises to vigorously promote the lead-acid batteries, but because of high pollution, this feature makes this product not to be optimistic, when the development of more than a helpless feeling. “Lead metal refining, manufacturing batteries, battery recycling process are pollution, cars on the road only when there is no pollution. Can not say that this is clean energy. Lead-acid battery is not a technology should be vigorously promoted. Currently Lead batteries in China has 45% of the production, Europe and the United States will use, but not manufacturing, not recycling, pollution in China. “Sha Yong Kang said.

In contrast, fuel cell is the number of experts look for direction, there are many international giants continue to send forces in this area. Fuel cell is the hydrogen and oxygen in the air into water by combination of electrochemical process and generate electricity plant. Fuel cell work without combustion, no moving parts, with the energy conversion efficiency (actual use efficiency as an ordinary internal combustion engine 2 to 3 times), no noise, long operating life, high reliability and good maintainability; it’s the only a product is water that is really clean, renewable requirement. From 1994 a fuel cell vehicle came to just over a decade now, technology is growing very rapidly.

Action, the current world countries the development of fuel cell, fuel cell vehicle technology to a very high concern. Toyota has announced that the first one fuel cell vehicles will be available in 2015. Last year in September, Toyota, Honda, Hyundai, Ford, General Motors, Daimler, Kia Motors and other well-known joint statement, called upon the Government by 2015 to build more hydrogen fuel infrastructure. If this goal can be achieved, from 2015, worldwide there are hundreds of thousands of hydrogen-powered vehicles will be gradually achieved commercial production. Although the cost of fuel vehicles still very high, but yes Zhenzheng meet clean standard technology, industry believes that with expanded its production scale, reduced costs a matter of when.

At the same time, hydrogen has become the safety of all concerned that the focus of this, Zi-Feng Ma replied that the security issues around the world on hydrogen technology very hard, hydrogen as petrochemical, metallurgical and pharmaceutical industries important raw materials, their storage and transport arrangements have a very good solution. We are 973 project team is involved in the development of national standards board hydrogen storage and international standards, the current laboratory of the hydrogen cylinder had reached 70 MPa, while only about 35 when commercial MPa greatly enhanced the safety factor. In addition, the hydrogen source is diversified. Currently in Shanghai, very different peak and valley power, tight supply in summer, while spring and autumn off the power supply, use of peak and valley power to electrolysis into hydrogen. As for the Shanghai Baosteel, Shanghai Petrochemical and other large enterprises, the hydrogen product is already a large-scale, so that future prospects are bright.

The general direction, new energy vehicles will inevitably introduce new technology to promote the expansion of the battery. Zi-Feng Ma believes that the future will be fuel cells and batteries or fuel cells and capacitors to mix the advantages of combining the two is a good direction. “We know that a good power rating for the design of fuel cells, electrochemical hydrogen reaction by restricting its output power is stable, such as loading 60 kilowatts of fuel cell vehicles, slow down or stop when the fuel cell is always at work, then electrical storage devices give the extra charge, when the vehicle acceleration or hill climbing, the fuel cell power can not become 70 kilowatts from 60 kilowatts, this will be supplemented with the electrical storage device, this combination is conducive to the improvement of dynamic performance . short, we should select some more direction, more cutting-edge place to look. For instance, we present and Michigan University to lithium – air batteries such as the latest technologies, this relatively remote, only after 15 years to have a big development. ”

Sha Yong Kang believes that the technology of new energy vehicles is very diverse, do not have to put all eyes are focused on the battery itself. The concept of new energy sources must be wide, with broad concepts have new ideas. Perhaps in the near future will be able to find a new liquid fuel that can replace the methanol and ethanol. Another example is the wireless power technology used in the car. Although there are some problems of remote applications, but the Massachusetts Institute of Technology in 2007, when the technology can be lit by 2 meters outside the 60-watt bulb, which gives people unlimited reverie. The future of the wireless power technology combined with the car might be a viable option, save the plug so cumbersome steps.

New energy vehicles is undoubtedly the future direction of development, after 50 years is likely to fade out of traditional diesel when the stage of history. But as the sand Yongkang said: “The development of new energy vehicles thought to be widened, staring at an immature technology can not blindly launched production. Can not see the market engaged in the project only to the research funding, subsidies to state action.” Japan Toyota, Honda and other manufacturers, such as the 1st decade of painstaking research of a technology, once mature, strong market, other companies can only be far behind to catch up. In contrast, Chinese companies want to bend to overtake the field of new energy vehicles, still need to calm down.

U.S. local time on June 7, Apple Worldwide Developers Conference (WWDC) in San Francisco MosconeCenter opening, Apple CEO Steve Jobs officially announced Apple’s iPhone, the fourth generation of products – iPhone4. High-definition screen, the unique design of the square body and many bright spots to be those who are so excited.

Square for iPhone4 unique body, MiLi the use of patented technology and unique design, will build its clamshell PowerSpring4 turnkey plug-in battery. PowerSpring4 original Apple interface, stylish and simple design style can be described as a perfect match iPhone4. Will PowerSpring4 hold in your hand, it is more like a fashion iPhone4 case, yes, PowerSpring4 is the thinnest on the market iPhone4 external battery; ABS material plus piano paint, fashion, comfortable feel and iPhone4 fine even take the same.

MiLi, well-known brands as Apple authorized, the information in iPhone4 has a unique advantage; and its subsidiary excellent R & D team has rich experience of Apple’s product plug-in battery research and development; It is not difficult to explain why the can so quickly launched MiLi the world’s first iPhone4 plug the battery – PowerSpring4. Currently MiLiPowerSpring4 has limited sales, with general availability in July MiLiPowerSpring4 will be brought to Apple fans more surprises.

So far, the United States, many families have installed their own solar energy, because solar energy can replace those who will soon be exhausted traditional energy, without fear of its binding. In fact, solar panels can be installed on the roof, so from Natural sunlight will be a constant supply of electricity. and then can promote the formation of a clean environment, but also reduce the threat of global warming. If the Cumbria and Cheshire in England has installed solar panels, then the two regions will become more environmental protection is more green, but different from the current situation.

The electricity bill for those who are firmly bound to people, this is undoubtedly great news, because the solar panels can significantly reduce the energy consumption of the user in the traditional time, then, electricity prices also drop down.

As the installation of solar panels on the appearance of the original house does not produce any damage, so worried about the battery plate will make a house become ugly just superfluous. At the same time, solar panels not only operate under sunny conditions, even in the often appear cloudy uninterrupted use of the weather will only run off from that a little sunshine.

    First, we all know that when the lithium battery from overcharging, over-discharge or charge and discharge current is too large, the capacity of the battery life and has tremendous damage and even cause cell deformation or explosion, it is generally in the internal lithium battery are set to protect the electronic circuit batteries. When the battery from overcharging, over-discharge current is too large, will be cut off and the external connections. As some friends, as reflected in: cell phone charger in the boot when a call come in automatic shutdown will cause problems. In other words, the initial battery charge, low voltage, and when a call comes in, the phone to ring, it must maintain a certain amount of power. In the case of low voltage, battery current will increase, excessive current caused by the battery protection circuit moves to cut off the battery and the external connection, causing the phone to automatically shut down.

    Second, in order to improve the charging efficiency, lithium first constant current charging with high current to power 90%, the battery voltage of 4.2V, it almost takes about 2 hours; and then to a small constant current charging until the battery is fully charged action until the internal protection circuit, it takes about half an hour, taking into account the battery, charger, individual differences in the products, lithium battery to charge 3 to 4 hours is appropriate.

    Taking into account the phone battery indicator error and other factors, when a green light when the charger can charge 1.5 hours more. Another point we should note that lithium batteries will not impose long-term place to sleep, normally require activation before use. Usually after 3 to 5 charge and discharge cycles can be activated. Known under the first two reasons, the lithium batteries expect for sleep through the long charge to activate no sense. Because after the battery is full (about 2 ~ 4 hours), has been movement on the lithium battery protection circuit, cutting off the external power supply. As the role of protection circuits, long charge on lithium Although there is no harm, but the protection circuit will start the energy consumption of batteries, if the protection circuit to lose effect, ranging from damage to the battery, and at the damaged phone, again the idea of the consequences of not . Therefore, taking into account cell phones, lithium batteries and chargers, individual differences, charging three times before and after the charge are the same, only 3 to 4 hours.

Survey results show that, after the patent score and enterprise rollup, the overall average or above on account of patent total score Zhi Jin Xing’s “Syndicated news power rankings” in, NEC ranked first, the second is the Sanyo Dian Ji, the third bit is Mitsubishi Chemistry. NEC to 34 the number of patents, ranked in the top five companies in the fourth, but has a number of concerns due to the higher degree of patent, the comprehensive strength ranks the first. The largest number of patents is the comprehensive strength ranks fourth is the GS Yuasa, a total of 84.

Common lithium-ion rechargeable battery’s PA3399U-1BAS，PA3399U-2BAScathode adopt cobalt oxide (LiCoO2), but the problem is the high price of cobalt. To solve this problem, manganese lithium-ion rechargeable battery using lithium manganese oxide cheap (LiMn2O4). Compared with cobalt, manganese and relatively low prices and more readily available, thus it can reduce battery costs.

       The product is expected to be used in TV remote controls, LED lighting, and other low-power products. FK890 Using this battery remote control until the remote control can be eliminated or the generator damage do not need a new battery.You just need to shake it and then it will supply sufficient electricity to change the programme.

     VpGB battery will be on display in Tokyo Techno-frontier from July21 to 23. Then, they will cooperate with TV manufacturer first and launch the TV  products of “never have to replace the remote control batteries”. Hope that this product access to China, and they should not costs too much, or Chinese consumers will not buy them.

Thinking about getting a netbook but concerned that people will spot you carrying a computer all over town? Not to worry. One chinese company has the perfect camouflage for its netbook. The mini-laptop has a built-in handle and a case that basically makes it look like a handbag when the lid is closed. Oh yeah, there’s also a sparkly red heart shape on the pink cover. This one’s clearly not for everyone.

All the company’s innovative ideas went into designing the outside of this netbook though. Under the hood, this netbook has all the usual components… from about two years ago. it’s available with either a VIA C7-M processor or Intel Atom CPU. You also get 1Gb of RAM, a 160GB hard drive and WiFi and Ethernet connectivity.

The handbag netbook should sell for about $300 in China.
