Wireless Charging Essay

To make the charging stations more convenient for tesla vehicle users, the company aims to build more charging stations in the future and tries to improve the battery technology so that there is less electric consumption.

The Motorola Corporation was founded in 1928 when its’ Owners Paul and Joseph Galvin decided to start a business in the area of battery storage. Paul was interested in improving on the technological advances that had taken place to date in that field. As a result, his motivation and hard work allowed investments to be made in the manufacturing industry toward the promotion of that product. The first device made and marketed by the company was a power converter designed to allow battery-powered radios to run on household

Wireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past. The concept exploits century-old physics and could work over distances of many metres. Consumers desire a simple universal solution that frees them from the hassles of plug-in chargers and adaptors."Wireless power technology has the potential to deliver on all of these needs."However, transferring the power is the important part of the solution.

Abstract— Near Field Communication (NFC) is a set of protocols and specifications for the wireless exchange of information over a short range and is the next technological stepping towards ubiquitous computing. It builds upon the existing RFID technology. NFC is a set of technical specifications and standards for transferring information between two proximate objects via the inductive coupling of radio frequency fields at 13.56 MHz. This technology will save the time. NFC technology allows people to integrate their daily-use loyalty cards, credit cards etc. into their mobile phones. In addition to integrating those cards into mobile devices, NFC technology brings innovation opportunities to mobile communications. It enables two users to easily communicate and exchange data simply by touching two two NFC enabled devices to each other.

There is an extensive amount of science break-through and amazing technology being discovered and researched on a daily basis; but unless that technology has a purpose, it will never surpass the research stage. Wireless power has been pushed aside in the past by researchers due to the fact that there was not a large market for a system like this. Within the past 20 years, portable electronics – i.e. mP3 players, PDAs, cell phones, digital cameras, video game systems, laptops – have become household items. With the amount of portable electronics that are being frequently used, batteries that are used are either quickly disposed of or need to be recharged often.

Wireless technology has become an increasingly crucial part of today's world. From health care and retail to academia across the world, wireless systems are improving the rate and ease with which data is sent and received. Two specific examples of the wireless technology used today personally and professionally are local area networks (LAN) and personal area networks (PAN).

The advancement in technology has made the automobiles very safe, fast moving and efficient. Yet, the development in this field has not stopped, more and better ways for using the full potential of the automobiles are being discovered or invented. Nowadays, the latest development in this field is the use of Electromagnetic energy. Scientists and researchers

Wireless data has become the technology of the future. Data is being passed from one location to another without the human eye detecting this transaction. Wireless data is transferred in many forms from home networks, business networks, and cellular networks. Each of these networks operates on a different scale and technology.

In the field of telecommunications wireless communication is the most advanced and widely used method for long distance communication. Wireless Communication today faces various

In the current wireless networking standards, omni-directional antennas are used to establish connection between the base station and the user. The radiation emitted from this antenna is spread uniformly in a horizontal manner. These antennas are employed because the base station is not aware of the location of the user. Hence most of the radiated beam is lost or dispersed. Furthermore radiation from neighboring base stations with the same frequency will cause interference. If it is possible to concentrate the beam/radiation only the user and introduce nulls in the area of the interference, most of the radiated power can be made useful and gives users with extended range.

In this paper, authors conducted a survey of RF power density in urban environment in order to design a rectenna for harvesting ambient RF energy from free space. Although, RF energy spread out in free space have very low power density levels of 36nW/cm2 at GSM 900 (BTx) and 84nW/cm2 at GSM 1800(BTx) which is a three times the MTx power therefore only power density of base station is considered. By the knowledge of the power available in free

The projections of the usage of electric vehicles, as well as the projections for renewable sources, show that there would be an increasing number of people using electric vehicles in the near future [3]. In order to avoid problems related to high peaks of demands due to simultaneous charging of batteries, usually in the evenings after work, it would be necessary to manage their charging through the use of smart charging technology.

Communication of data between tags and a reader is by wireless communication. Two methods distinguish and categories RFID systems, one based upon close proximity electromagnetic or inductive coupling and one based upon propagating

Gathering ambient energy from radio frequency is called RF Energy harvesting [1-2]. This includes designing of antenna and some additional circuit that convert EMF radiation into DC voltage so that it can be used to drive low power devices. The concept of wireless power transmission is the basic principle behind RF Energy radiation in free space. The wireless transmission includes Bluetooth, GPS, Satellite communication, Wi-Fi, DTV. The wireless technology reduces cost of installation by eliminating wired transmission thus it is easy for us to carry wireless

The Automatic Power factor Correction device is a very useful device for improving efficient transmission of active power. If the consumer connect inductive load, then the power factor lags, when the power factor goes below 0.97(lag) then the Electric supply company charge penalty to the consumer. So it is essential to maintain the Power factor within a limit.
