At the time, tesla is a series of experiments are carried out using coil, created the wireless power transmission. In 1990, and tesla began his research, and try to make electricity like broadcast across oceans, afterwards because of huge investment, the technology of "death". Although tesla research ultimately no results, but his original wireless power technology idea is bold enough.Second, the development of wireless charging technology tesla coil at the time didn't get, but in the mid - 1920 - s, Japanese H.Y agi and S.U da theoretically confirmed this solution is a completely different from special power supply way of cable transmission, the wireless power supply technology, photoelectric coupling, electromagnetic coupling main magnetic resonance, etc. Three different ways.A power supply, the current wireless power supply technology, photoelectric coupling, electromagnetic coupling main magnetic resonance, etc. Three different ways. 1, electromagnetic coupling, electromagnetic coupling for power engineers, in the familiar, the transformer is to use this principle to transfer energy. If separate two winding transformer, is something of a wireless power supply. Rechargeable electric toothbrush is a typical case, but the use of electromagnetic coupling way has a lot of disadvantages, not high magnetic permeability of magnetic core as a medium, the lines of magnetic force can lead to serious spread into the air, resulting in a decline in transferring efficiency, especially when two coil from down badly. So this way is only suitable for small power, close communication, for high-power, long-distance wireless power supply is not so good this way. 2, photoelectric coupling photoelectric coupling is to convert electrical energy to light energy, such as laser, energy transfer to the destination by light into electricity. The wireless power supply technology is more intuitive, photoelectric coupling also can well restrain interference, and the application of the photoelectric conversion technology is relatively wide. The unidirectional, but made by light transmission determines its transfer path has certain defects, there can be no obstacles in the transfer path. So this kind of technology, also has the corresponding defects. 3 people on magnetic resonance and magnetic resonance coupling has a noun is unknown, its principle is similar to the principle of sonic resonance, if the two media have the same resonance frequency, can be used to transfer energy. Magnetic resonance chamber are currently studying a way of power transmission. In 2008, Intel engineers had to the technology as the foundation, in according to the power three feet lit a 60 w light bulb.In September 2010, Fujitsu, wireless charging technology using magnetic resonance between the charger and the device of the air transport charge, the coil and capacitor in resonance between the charger and the device. Fujitsu said the system can be widely used in the future, such as for electric car charging area and the power chip, power transmission, adopting the technology of the charging system the required charging time is only about one over one hundred and fifty of the current. At present, Japan plans to set the charging points in 2012.Also developed by Fulton eCoupled technology originated in the 19th century Faraday discovered electromagnetic induction principle, when the current through the coil generates magnetic field, the corresponding equipment will be affected by magnetic field creates an electric current, electric transmission is completed in "wireless" way, and eCoupled technology can also be from of different functions of the same electrical appliances, and the corresponding power adapter. Initially, Fulton will develop eCoupled technology used in parent company amway water purifier, water purifier for bulb wireless power supply. According to the Protable Design, 10th, 2010, is expected in 2013, the potential markets in the world of wireless charging equipment capacity is close to $14 billion, to 2014, wireless charging equipment shipments will reach 250 million units.Current wireless charging alliance enterprises include: Atmel, Callpod, LG electronics, national semiconductor, nokia, samsung, Olympus, philips, Rohm, SangFei communications, SONY Ericsson, Texas instruments, such as photoelectric in the 60 companies. China as the world's largest mobile communications market, huge application demand. China SangFei communication is one of the 10 member enterprises alliance of wireless charging, the chairman of the board of directors of the company, according to the standard, will surely push for wireless charging market to develop in the direction of depth.Four, the status quo of wireless charging technology wireless charging technology in foreign countries a lot of research institutions and enterprise groups is still in a lot of energy research and demonstrates the feasibility and industrialization, but China in tsinghua university, Beijing university of science and technology, Harbin institute of technology, north university and some other scientific research institutions and in some cities such as shenzhen, Shanghai high-tech enterprise has fully into the hot and forward industry, in the electronic information products such as mobile phones, laptops, and widely used in life such as small home appliance is beauty skin care products, and small-scale production Current wireless charging technology is becoming more and more frequently appear in each big communication technology on the power of new technology, companies have also launched their own research. In June 2007, the United States at the Massachusetts institute of technology research group released "to the distance of about 2 m from 60 w light bulb carry electricity, and lit it" experiment report, make the attention of the world. To start, as numerous manufacturers and research institutions in order to achieve the "wireless power" practical, also began to actively research and development. In August 2008, wireless charging union held a press conference in Beijing, announced the wireless charging international standard introduced to China, bret lewis, vice President of wireless charging alliance, nearly 60 members including energizer, LG, nokia, etc. Windows 7 in 2009 conference, Microsoft CEO Steve ballmer is brought in the latest wireless video output and wireless power supply technology. Wireless charging technology in city transport, also in March 2010, the wireless charging of electric cars in Seoul, South Korea, large amount of the first trial run in the park.Fiver 1 wireless charging technology outlook, wireless charging on a mobile phone application is one of the biggest mobile phone market in China, and 60% of the world's mobile phones are made in China, so the wireless charging technology is bound to take root in China. To realize wireless charging mobile phone, the current must have two parts: transmitter, connected to the power supply, to the vast space launch power; Receiver, general installation on the electronic products, used to receive electrical energy. At present only part of the mobile phone supports wireless charging and the dimensions of the charger is still a little big, it was reported that in recent two years, wireless charging receiver will fully "lean", become the wireless charging accept chip embedded in the mobile phone products, the size of your fingernail. "At present, nokia, philips, samsung, SONY Ericsson, and research in motion (RIM), and many other international well-known mobile phone manufacturer is to support the technology, wireless chargers are also likely to be bundled with mobile phones for sale." Mobile phone is just the first goal, after PMP/MP3 players, digital cameras, laptops, etc all can use the new low energy consumption, high compatible wireless charger. Is expected to realize long-distance wireless charging within five years. How in the future, wireless charging technology will change our lives? Convenient since needless to say, in addition, wireless charging is more secure, without connector leakage, leakage, electric leakage and other security hidden danger can be completely avoided. Someone worry about radiation, this technology was first used in water purifiers, until now already has eight years time, security has been validated by the 36 countries, will not bring harm to the human body and environment. According to introducing, wireless charging generally is through the electromagnetic field energy, and human and the human side of the majority of items are magnetic. At present, the efficiency of the accept rate continues to improve, will soon be able to achieve 98%. 2, wireless charging technology application in medical equipment power supply of implantable medical device at present rely mainly on implanted battery, its biggest drawbacks is to deal with the problem after the battery runs out, whether replacement batteries or buy permanently, there exist hidden danger, therefore, the portable external for wireless charging can be implemented as low power wireless sensor network (WSN), can be recharged and patients medical devices implanted in the body, also can recharge under the special circumstance of automatic test system. Some implants volume is very small, can't accommodate the battery. Such as cochlear, it needs to be surgically inserted instead of inner ear hair cells play a role of an electronic device. The use of external power wireless charging methods for continuous provide high can for implantable medical electronics. Using radio frequency links, not only can achieve energy transfer, also can control and query for implantable medical devices. In addition, implantable medical electronics the service life and storage life are no longer limited by the battery. For example, a cardiac pacemaker (necessary power supply signal activation of cardiac recovery and maintain normal), at present, the cardiac pacemaker implantation in the human body, after 8 to 10 years or so need to replace the battery. That is to say, although installed pacemakers, then every eight to ten years will also need to be an operation to replace pacemaker cells. Imagine if a pacemaker used the wireless charging technology, it is more convenient? More don't happen surgical failures, chest infection, etc., the postoperative quality of life of patients could get great improvement. 3, the wireless charging technology application in mobile intelligent terminal equipment in the league of wireless charging technology planning, the future of around 125 w high power electronic equipment will also support.4, wireless charging technology in electric vehicle application along with the rapid development of economy in our country, the national corresponding preferential policies, the subsidy policy, still in the new policy and a series of policies introduced gas energy, further promoted the private cars increase, the international energy and environment has become the world's most current concerns, and alternative energy shortage, environment pollution and protection to the developing of the new environmental protection. The electric car is the first developed a kind of environmentally friendly new energy vehicles, including battery electric vehicles, hybrid electric vehicles and fuel cell electric cars. The battery electric vehicle technology has matured, many manufacturers have begun to production, around also in the construction of charging stations. But the battery charging issue has been the researchers have a headache, and, therefore, solution of charging technology, will greatly promote the development of battery electric vehicles. Wireless charging technology to be applied in electric cars, on the one hand, during the construction of roads and buildings, by the power supply unit according to plan in advance in the intersection, public parking lot parking, parking space and garages unit or village below embedded wireless charging the charger, and make the charger connected to the grid or solar panels; Car manufacturers, on the other hand, want to install in car at the bottom of the acceptance of wireless charging device, and electromagnetic devices such as xu and connectivity; In addition, the relevant state departments to the same emission and receiving signal frequency, can make its are general.On the application of wireless charging technology applied to electric vehicles, should also pay attention to the following questions 1) countries should publish relevant policy, encourage, support and standardize the development of the wireless charging car and the construction of the charging infrastructure, wireless charging is a fledgling can even calculate is not start field, its effective development can be largely solved the electric car development a bottleneck. 2) no matter which way eventually to take charge, using what kind of battery, state and local relevant departments should be on its frequency, safety, environmental protection, energy saving, etc, do research, avoid the harm to human body and environment. 3) in the actual use process, because the transmitter on the ground, want to protect, so much rain in the place of waterproof facilities must be used.Influence, significance and wireless charging technology has the advantage of portability and versatility, and can make a variety of devices using a charging station, perhaps in the near future, all kinds of power adapter cut hard also disorderly situation will disappear, and the use of public charging stations mobile devices become a reality. Its significance and influence to the public were remarkable. (1) portable due to waves transmission has nothing to do with the charging interface equipment, so if the wireless charging technology once popular, not only will make electronics from the plug and cable tie, charging more convenient, and it will make different brands, different interface charger incompatible problem is resolved. In the near future, global wireless charging infrastructure will be in every home, coffee shops, airports and other public places, consumers can use the wireless charging equipment charging anytime and anywhere. All this has become very convenient because of the existence of wireless charging. (2) beautiful sex wit
