85% Power Utilization

According to foreign media reports, the Japanese electronics maker Fujitsu has recently developed a wireless charging system in using magnetic technique, they plan to build in 2012 and introduce to the market. Within two years, people no longer need cable when charge to a cell phone or other equipment.

Fujitsu's new charging system that can simultaneously charge multiple devices to include: mobile phones, digital cameras, notebook computers and other mobile electronic devices, they will no longer charge the need for wires. As long as the specified range, the device can be charged. Therefore, we expected to see wireless recharging after "hot spots", which stores and cafes in the Wi-Fi wireless Internet access area is very similar.

Fujitsu also try the system for electric vehicles. China announced the company, this technology is the world's first, it works by magnetic energy is sent from the wireless charger to the electronic device. It uses a roll of wire and a capacitor charger and power to the wireless receiver to be transferred between the resonance, Fujitsu to this method is called "magnetic resonance method." Fujitsu said, "This technology has opened up a new path, it will be small, wireless charging capabilities into mobile phones, making a variety of mobile devices can also charge the charger without the location restrictions. Researchers also found that more potential uses of this technology, thereby including the mobile electronic equipment and various equipment, including electric vehicles to recharge. "

It is reported that the company has designed a slim, lightweight power receiver, and has produced a prototype for charging built-in wireless cell phones. Fujitsu claims that the prototype cell phone can charge anywhere within the electricity transmitters, the energy utilization rate of 85%. The company claims that they pass the test found that the size of the transmitter coil may cause the different performance of the charger. They have found a coil size that required for optimal effective charging for three devices (cell phone battery charging), the charging time is less than 10 minutes (cell phone accessories for less), 150 times faster than usual charging speed.
