Over the next decade, the most vibrant Wireless Power Transmission (WPT) markets will be the contactless charging of portable and mobile equipment, in particular consumer electronics and electric vehicles. This is the focus of a new report, "Wireless Power Transmission for Consumer Electronics and Electric Vehicles 2012-2022." The research carried out for this report describes technologies that will be a stepping stone to contactless power for a high proportion of static consumer, industrial and military electronics and electrics.
For now, it primarily concerns wireless charging of batteries in portable consumer electronics and in electric vehicles. Both travel considerable distances and ready availability of standard, convenient, contactless, charging capability are key to their further growth in adoption. For example, the user will enjoy ever greater functionality and longer hours of use of mobile phones despite the on-going shortcomings of their batteries.
Our research, highlighted in the report, concerns transfer of Watts up to high power of the order of kilowatts at ranges of about one millimeter to about 60 centimeters. The WPT of concern usually involves static transmitters and a larger number of receivers incorporated in what is usually portable or mobile equipment.
The transmitters are usually hard wired to AC mains or energy harvesters such as photovoltaics, there being a trend towards multiple energy harvesting. It will only become a mass market if more comprehensive standards are widely adopted and the manufacturers of the portable and mobile equipment incorporate the receivers during manufacture. We forecast the demand by power level and consider other criteria such as technology, range, and region of adoption.
For success in the automotive area, those using pure electric cars seek to avoid range anxiety in some other convenient way. Standing in the rain to plug in an electric cable which then trips off for safety reasons does not qualify though almost all the investment in vehicle charging infrastructure is currently going into just that.
Convenient electric top up of hybrid electric cars is also an important market driver as they become capable of all electric range of more than 100 kilometers, creating the opportunity to pay one fifth as much for "fuel" due to a quirk in the taxation system (electricity is cheap) and to save the planet as power stations get cleaner. And it has been established that, as with gasoline pumping, a high proportion of women in particular find it unpleasant and even dangerous to get out of the vehicle and plug in for electricity. With WPT they stay clean and safe inside the vehicle.
