A study on wireless charging and iX Quad offerings

  • blog_image

We are in the midst of a digital world where we are not hindered by cables. Everything has become wireless. Wireless communication has revolutionized the way we do business and keep in touch with our loved ones. Many studies was being carried out for wireless transfer of energy. Although the wireless transfer of energy has not reached great distances, it has made an impact.

Wireless charging of mobile devices attracted a lot of attention when it was first introduced. As the days progressed, it became commonplace. However, the technology has a lot of potentials to evolve since the devices rolling out are compliant with Qi-standard. In this discussion let us look into what goes inside wireless charging and what iBUX has to offer.

An introduction to wireless charging

The question arises why the need for wireless charging when it is not so efficient compared to wired charging. However, wireless charging has a great set of benefits and can be spanned to other domains. For instance, research in wireless charging is being taken over to charge electric vehicles. Research is also being done to support wireless charging over great distances.

We can summarize wireless charging with their set of pros and cons. This innovative form of charging is very convenient and fosters a tidier desktop. Wireless charging does not have any mechanical moving parts and poses no threat of electric shock. However, as a downside, there are risks associated with heating and slower charging time.

Standards in wireless charging

As with any technological novelty, wireless charging matured by co-existing with many standards. However, the most widely accepted standard is Qi. The Qi standard was developed by the Wireless Power Consortium (WPC). The other standard that was in force for a short period was Powermat.

Qi is currently the only standard prevalent among the masses. Technically, Qi applies to inductive charging over distances up to 40mm. Many mobile device manufacturers have embraced the Qi standard. The giants in this list include Samsung, Apple, Nokia, LG, Sony and Huawei.

Qi has also been defined with power ratings. Beginning with minimum power amounting to 5W, the ratings extend way up to 25W. In between the extremes are the support for 7.5W and 10W. The medium and high specifications of power delivery amount to 120W and 1kW. These specifications are for computer peripherals and other accessories respectively.

Wireless charging explained at length

Essentially, there are three types of wireless charging - non - radiative charging, radiative electromagnetic resonant charging, and uncoupled radio frequency (RF) wireless charging.

Non - radiative charging: These are charging pads that use tightly-coupled electromagnetic inductive technology.

Radiative electromagnetic resonant charging: These are charging bowls or through-surface type chargers that can transmit a charge over a few centimeters.

Uncoupled Radio Frequency (RF) wireless charging: This form of charging allows energy flow over a few feet.

Wireless charging operates on the principle that a time-varying magnetic field induces a current in a closed loop of wire. A copper coil is used to create a fluctuating magnetic field, that can create a current in one or more receiver antennas. The amount of power induced in the receivers increase with an appropriate capacitance added.

FAQ

  1. Is wireless charging fast catching up? Will we see a mass acceptance of this technology in the coming years?

Yes, wireless charging is fast catching up. We will definitely see a wide section of the people adopting this technology. Since wireless charging is a major productivity gain wherein the presence of cables is overcome, people appreciate the technology.

        2. Is Qi the most widely accepted standard? Are there any other standards that are coming up?

For now, Qi is the most widely accepted standard. Qi standard evolved over a period to incorporate the latest and the best. For the moment Qi has virtually monopolized the market and there is no scope of other standards arising.

    3. What are some future innovations of wireless charging that we can expect?

There is steady research going on to introduce wireless charging into areas like electric vehicles. The scope for applications of wireless charging is virtually unrestricted and we may expect many innovations coming along.

4. Does wireless charging pose any health risks?

No, wireless charging has so far not posed any health risks. Wireless charging with high power may be dangerous if we are directly in the path but by default they are harmless.

Conclusion

Be actively aware that wireless charging is here to stay. You must not be overwhelmed when this technology is widely in use. Rather, you must make an effort to learn about the fundamentals and make full use of what technology has to offer. Currently Qi is the widely accepted standards and you must endeavour to understand its internals.

There are several content available online which will inform you on the pros and cons of wireless charging. Please note that wireless charging is by far very much an advantage. Its high points far outweigh its misses and in the coming future you would surely embrace this novelty. The iBUX product iX Quad delivers well on power and safety standards.
