Promising technologies to improve wireless charging
At Pepcom's Digital Experience exhibition held in the CES 2013, the company PowerbyProxi New Zealand has demonstrated a wireless technology that allows you to recharge AA batteries at the same time, smartphones and even helmets.
PowerbyProxi says its wireless technology standard improves the Qi (pronounced "tchi") currently used in systems of wireless charging for tablets or audio systems. According to the Wireless Power Consortium, the origin of the Qi standard, the products of nearly 140 manufacturers are currently certified to this standard. According to Greg Cross, founder and president of PowerbyProxi, "wireless technology developed by his company uses loose coupling load, which, unlike the Qi standard more restrictive, does not impose a strict settings to devices to receive a maximum load efficiency. The President announced that PowerbyProxi chargers and other products compatible with the technology would be available within a year to 18 months.
During his demonstration, Greg Cross has evolved a Nokia smartphone over a charging mat to show how to work this wireless technology, regardless of the place where the instrument. Then he placed three mobile in different areas around the charger to show that they were all loaded at the same time, the same power as that provided by a wall outlet.
Charging box
Fady Mishriki, founder and CEO of PowerbyProxi has demonstrated AA minirécepteurs integrating wireless (they occupy about 10% of the height of the stack). CEO of PowerbyProxi inserted the batteries in electric truck that was then placed in a box load. LED battery equipped mini receiver began to flash, indicating that the charge was underway. The box can load up to eight stacks of multiple devices simultaneously. "It works with all types of batteries, rechargeable AA batteries, but also lithium-ion batteries or even custom," said Fady Mishriki.
As technology Qi, PowerbyProxi uses techniques based on load magnetic induction. For this to work, the loading apparatus must be in contact with a surface load, like a carpet of charge. Or, in the case of the load box, they must be surrounded by a load surface on three sides. To date, Duracell is the first and leading provider of carpet charge. They are equipped with Powermat technology developed by Duracell.
Recharge cars like computers
Magnetic resonance technology, which allows you to recharge devices placed near a charger should be available very soon. For example, magnetic resonance technology developed by WiTricity can be used to charge batteries as well as car laptops. This technology is based on the same technology to transmit / receive coil from the magnetic induction, but it can transmit energy at a greater distance.
To make its demonstration at CES PowerbyProxi created his own material, but in the long term, the company does not intend to manufacture and sell its own products. It plans to license its technology to manufacturers of charging systems and mobile devices. "They may decline as multiple technology," said Tony Francesca, senior vice president of business development at PowerbyProxi.
The technology developed by the company in New Zealand has an intelligent processor for controlling the transfer of energy. If metal objects do not comply are placed on a carpet or in the load box, no energy is transmitted. According to Tony Francesca, "the ability to distinguish between compatible devices and devices containing metals (especially iron) is important, particularly for wireless charging technology used in the armrests of motor vehicles or charging mat" .
PowerbyProxi technology can be fully integrated into the motherboard of a smartphone. The receiver and the coil can be placed inside the mobile devices in addition to other components without changing the device itself. This is not the case in receivers compatible with the Qi standard. "In smartphones, they must be installed outside the motherboard to avoid overheating," said Greg Cross. Low Fransen, Chief Marketing Officer of Wireless Power Consortium (WPC), which created the Qi standard, confirmed today the technology was present in many smartphones, but it was not installed on the motherboard.
Greg Cross said a charging mat incorporating its technology allow simultaneous charging of up to three devices at full capacity (5 watts), or a total load of 15 watts. Qi standard currently allows a load of 5 watts, but it should go to 15 watts in a year.
