Does “Wireless Power” is possible?

Does “Wireless Power” is possible?

When the notebook computer, PDA, cell phone networks have shaken off the shackles of cable, or even headphones and microphone are also Bluetooth, free wireless communications into a new era, we still have a trace of regret – not far from the power line “care.”

Computers, mobile phones are power-hungry, full well the power that they can not lasting, “life”, with a Bluetooth headset, GPS module these gadgets are not immune, Ge Jitian (sometimes daily) to remember to feed them power, otherwise does not work on the strike, then hyun, then also no use of high technology! This is indeed a piece exhausting chore, and completely contrary to our lazy nature.

Therefore, solving the power cord is only for the “tail” of the most important wireless issues, of course, the biggest problem. Because energy does not allow to pass through the electrical wire is really incredible things. But depends on human effort Mody. Lazy people always come up with lazy approach. Can not rely on the power line as possible, to arbitrarily with “mobile” roaming around without worrying about power shortage alert, apparently full of great appeal. Who can get this thing might get a Nobel Prize in Physics have mention it!

From the theoretical analysis, the “wireless power” may have the following three kinds of solutions -

① Large Capacity Battery

The same as installing a submarine, “inexhaustible” nuclear power plants? Joke! According to the current capacity of the human grasp of nuclear energy, so that everyone hides one or two “Chernobyl” is simply head is filled. However, imagine no limit. If you can develop a super sound and safe energy storage capacity of the material, then the problem will be solved. And several years ago, and now the battery technology has been rapid, a few years Do not leap to a new level?

Moreover, the problem can be simplified look, we do not require “permanent move.” Have any electrical service life, as long as their life cycle without charge, or stretched to the charge cycle in weeks or months as the unit of measurement, in fact, perfect enough.

② wireless charging method

Imagine cooker, put up the pot of water to grunt away. Microwave oven is almost. RF IC card (RFID) especially, the card chip run completely by electromagnetic waves to transmit power. So, if there is a “magnetic table”, laptop or mobile phone on the table will be able to “learn” to power, the hassle of a power cord plug!

③ wireless transmission of electrical energy

Has been studying the long-distance wireless power transmission technology, using laser or directed electromagnetic transmission means such as, but on the computer, phone, and more doubtful usefulness, on the one hand to “targeting” requirement is too high, not as Plug a power cable is more convenient, on the other hand did not eat two guts who would dare to close the “energy beam” ah!

The first program is designed to enhance the energy storage capacity, power transmission, and in fact there is no “wireless” technology, but extended the time without charging it, may also be able to solve our problems. The latter two programs face the problem directly, technically you can have different measures, but the most difficult is the energy of the “conversion efficiency” not satisfactory, power efficiency is very low, not only economic, environmental damage, and whether to support electrical power consumption are in doubt. In addition, electricity is the only “Tiger”, with a wire transmission was off like a tiger cage in the solid, there was no danger, but whether the wireless transfer of power will put out the tiger? High-density large-capacity space electromagnetic waves will hurt the body, affect health? I am afraid these are the problems require long-term in-depth study.

Battery maintenance and correct use of skills

Laptop Batteries Laptop may say that the main source of inspiration. No batteries provide energy, you can not meet the needs of mobile offices. Then we can better laptop in the hands of a laptop Bale. Keeping a laptop battery and use of skills was the hardest thing for most consumers. Now, I tell you some maintenance tips, I hope you can help

1. After buying prevent laptop battery for more than three consecutive years of 12 hours of continuous load ;memory effect With the gradual improvement of manufacturing processes, such as lithium-ion battery charging characteristics load, constant monitoring of their depth in the four hours it is not necessary to send mobile phone battery laptop to get the right laptop battery died on the filling of two weeks or every month, leading to a laptop battery from deep discharge, the term sounds a bit scary actually a battery, no electricity and used directly on the computer turns off for it. However, if the number of times the depth of discharge is not too often

2. using the AC adapter when the battery should be removed first in order to avoid the battery “full blast more fully be used in notebooks currently on the market lithium-ion battery can be 300-600 times (a few can data) of the charge We can discharge and what their own, and now on the market Centrino models of battery life, and generally charge for the 5-6 hours of official data, the Pentium 4 models battery life of 3 hours, then taking lithium-ion Charge the battery charged and discharged 600 times the standard, you can use your own laptop battery charge, how long out. Some of my friends on the adapter when the battery makes for the purchase of the battery inside is worried whether he has more power, AC adapter connector began in the outcome of the results to calculate what your battery is wasted in a charging cycles. ;Indeed, this concern is unnecessary, because laptop battery power in the state can certainly not one hundred percent, so the use of the power supply certainly a full shipment. But now many manufacturers of notebooks with battery protection measures, as designed, for example, IBM notebook battery is only less than 95% of electricity will be charged if, but not absolute, with no opportunity to complete the design of the notebook OEM Manufacturers can rely weak in this respect a number. If you are really desperate, that its batteries could to remove it inside!

Laptop battery explosion after explosion of the battery appears likely to matter little. But take a load to an absolute No, Lithium-ion batteries, lithium batteries, a control circuit between them and guanli board and unloaded when the control circuit some features of the original Lingmin You will lose Huo Zhe direct failure, it can not effectively control the current, internal power core temperature led to an explosion. Or explode a battery short circuit inside the battery. But good thing is now on the market for notebook products are high quality batteries with foreigncountries, or direct people bought batteries, the quality is relatively better. The domestic part of the lithium-ion battery manufacturers arealso many imported from abroad and then connect to batteries. Such an old proverb says, if the selection of notebooks, as many as possible to prepare a number of manufacturers of products that consider the budget, not wrong

3. does not meet official standards of battery life, definitely a problem with the battery

If the battery standby time friends have reached less than ;official battery life standard,” then we can extend the number of ways:

Battery Life

How To Extend Laptop Battery Life

In fact, how to make good use of laptop batteries, how to extend their use of time and life issues,that is a big problem in the laptop users heart .laptop computer battery has a variety of methods and techniques, this requires that we use in peacetime more learning and application

when laptop battery use a long time ,It’s often sufficient dissatisfaction or even show damage.so that when we using ,we must take some measures to prevent. no matter your use of lithium or NiMH laptop power,as Possible after the exhaustion of charge to the basic power(Power less than 5%),This is the best way to avoid the memory effect. In fact, Lithium-ion battery has some memory effect,Is much smaller than the Ni-MH battery Bale.but,note that, when charging the battery, avoid too long , General control within 12 hours.

Battery life is not the length of time by the general use,But by the determined charge and discharge times. If you always loaded to the laptop without the battery down and then shut down the machine and even after removing AC power, the battery will not like the thought of it has to fully charged state.notebook batteries due to the battery control integrated ciruit,so even when the power is also shut down the computer power.As one connected to the AC power source,the battery begins to charge ,when turned on or off the power ,the battery would repeatedly charge and discharge,affect battery life.

To do this,use an external power supply when AC is best to unplug the battery, or battery state of their life exposed to heat affected.If the long-term without the battery, please charge and discharge at least once a month to ensure its activity.In the custody of the battery also has a need attention.Currently,most notebooks used in lithium ion batteries do not use if the time is often prone to the phenomenon of excessive discharge, may no longer be able to charge.But you are not careful dell laptop battery will happen.In order to prevent over-discharge,charge state in half to save it in a cool dry place ,and then once every six months ,then half of tis electricity to the state of charge .

In addition,Factors that affect battery life include the use of environmental temperature(Proposed use under 30 ℃),Battery storage temperature and the size of the battery suffered shock. battery will be old after use a long time,specific manifestations of resistance become large,when the voitage across the charge rising faster than,so easy to charge control circuit judge to have full capacity has naturally decreased.battery calibration is an effective way to deal with aging batteries,A small number of notebook battery calibration software will be dedicated. If you laptop does not discharge specific software ,you can follow these steps:

• Disable the screen saver.
• In the windows power management power scheme will be set to “always open”.
• In the alert tab will be “insufficient power waring”is set to 10%,the operation set to “no operation’.
• In power shortage alert”,set to 3%,operating as “pending”.
• The screen brightness set to maximum.
• Confirmed that all the windows closed, and save all the data before work.
• Sure the batteries aye charging more than 80%aften the power and unpiug all extemal devices.

After the discharge end of the notebook will automatically shut down after the power plug for laptop charging ,This process can be repeated 2 to 3 times, aim is to continuous low current discharge battery,And this discharge state in our daily use can not be achieved, the effect of discharge and those dedicated basically the same software.

Ener1 Inc help to develop new opportunities to use high-performance battery systems

american lithium-ion battery architect Ener1, Inc. active a announcement of compassionate (MOU) today with Russia’s Federal Filigree Company (MICEX: FEES) to advice advance new opportunities to use high-performance Dell RN873 battery systems to advance the believability and achievement of the Russian electricity system, which is adverse almanac ambience appeal on an crumbling grid.

“Compared to any of the alternatives, filigree accumulator is a quick, awful amount able way to break believability and adeptness superior challenges on any network, and abnormally one that is already operating at its limit,” said Ener1 CEO Charles Gassenheimer. “Russia and added arising markets accept the befalling to leapfrog the affectionate of systems that abide abroad because the charge for avant-garde solutions is so acute, and their absolute grids are already continued thin. The adeptness to abundance activity to use area and if it’s bare is a big allotment of that.”

To armamentarium the massive undertaking, FGC was accustomed ascendancy by the Russian federal government to access prices it accuse electricity generators by 51 percent in adjustment to reflect with absolute apple supply costs. Overall investment in Russia’s electricity area has added added than eight-fold back 2005, according to the Ministry of Energy, which predicts that the country will absorb $20 billion in 2010 abandoned to advance breeding and manual VGP-BPS10 systems.

Cooperation amid U.S. and Russian companies on activity ability and acute filigree development is aswell a focus of the mutual Presidential Working accumulation formed endure year by President Barack Obama and President Medvedev. That accumulation is co-chaired by U.S. activity Secretary Steven Chu and Russian activity Minister Sergei Shmatko, and will authority its next affair in Washington, D.C. in July.

“These improvements are a top antecedence footfall in Russia’s efforts to body up a adapted top tech abridgement that absolutely reflects the apprenticeship and engineering aptitude that abide there,” Gassenheimer said, acquainted that the country is aswell gearing up to host the 2014 Winter Olympic Games. “That all-around VGP-BPL13 spotlight has consistently been a above disciplinarian of new basement investment.”

FGC was formed in 2002 in affiliation with a about-face of Russia’s civic electric adeptness industry. FGC is listed on Russian banal exchanges and is about 78 percent endemic by the Russian federal government.
