Humanity is on the cuff of building the most advanced technology around wireless power that the world has ever seen and we are about to see the world of wireless charging unfold around us as the consumer electronics world embraces the concept.
But where can wireless power take us?
We already live in a very wireless world. We utilize Bluetooth, Radio, 3G and even 4. However one thing is sure, we still all need to plug in to get wireless power.
Stay tuned though – this is about to change.
At this time the focus is on inductive charging of common electronics like the mobile phone. Although the technology for an inductive charging pad is available today, what excites many is how this technology can be integrated in the everyday environments of where we live, sleep, drive, ride and work.
The day will come where wireless power is available to use through our desktops, table tops, vehicles , trains and will even support wireless charging of mobile devices in public areas such as coffee shops and waiting rooms.
Other areas of increased wireless charging interest is around the charging of vehicles and even house hold appliances like fridges and freezers.
How does the wireless power work?
It’s all about Electromagnetism. A current flowing through a copper coil creates a magnetic field which oscillates around the coil. When another coil is brought into the range of the magnetic field then current will begin to flow in the receiving coil, which can then be converted back into an electric current which we use in electronic devices.
The main issues around wireless charging have been around how to make this a more efficient technology. Does the efficiency of this technology been an issue in the past? Well, yes it has. In some cases we would see a lot of power consumption for not so much chargeable energy. As a result, we would probably see slower changing times which would only add to the frustrations.
A concern for many is the idea of interoperability, which is essentially the ability to charge multiple devices at a time from the same charging station or depot. This is why we currently have the debates around wireless standards. The leaders behind wireless standards like Rezence and Qi continue to battle on this one each with their own set of benefits and concepts around how the technology is to best work.
The concept of wireless power availability anywhere you go has definitely got the potential to occur very quickly. I think that in many cases we need to see a growth firstly in the number of devices that actually have wireless charging capabilities and further to that, the support from corporate entities to adopt the idea and provide the incentive to use the capabilities in public areas.
The wireless charging industry is potentially held up somewhat by efficiencies, standards and the adoption of wireless power. There is a lot to look forward to in the coming 12 – 24 months.
