according to the daily telegraph of september 15, fujitsu, a japanese technology company, has created asystem capable of simultaneously charging multiple portable electronic devices such as mobile phones, digital cameras and laptop computers without the need for cable connections。

　　electric cars users may also eventually be able to charge their vehicles wirelessly using the same technology，said the company, which unveiled a prototype system at the institute of electronics, information and communication engineers conference at osaka prefecture university. claiming to be the world's first of its kind, the technology works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device。

　　the system enables wireless charging at distances of up to several metres, with the ultimate aim of installing public "charging spots" on the streets in order to enable easy charging around the clock. scientists at fujitsu laboratories are planning to commercially sell products incorporating the new wireless charging system as early as 2012 but did not disclose how much they would cost。

　　"this technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position with respect to the charger," the company said in a statement。

　　mobile phone users in japan can currently top up their batteries using disposable portable plug-in battery-operated devices, available at most train stations and convenience stores. however, phone companies warn prolonged use can damage the phones。

　　the company added: "we are also looking at applying the results of this work to fields other than portable electronics, including power transmission between circuit boards or computer chips, and providing mobile charging systems for electric cars."

　　据《每日电讯报》9月15日报道，日本富士通公司研制出一套可以同时为多个便携式电子产品(如手机、数码相机和笔记本电脑)无线充电的系统。

　　富士通公司在大阪府立大学电子信息通讯学会的会议上推出这一原理系统。该公司称，电动汽车的使用者未来也可以利用这种无线充电技术为汽车充电。富士通公司称，该系统是世界上首个无线充电系统。这项技术利用充电系统和电子产品之间的磁场传输电能。

　　该系统可以在距离电子产品几米远的地方进行无线充电。研究人员的最终目标是在公路旁建公共的“充电站”，以提供便捷的充电服务。富士通公司实验室的研究人员计划最早于2012年让采用这种系统的产品上市，但他们未透露这些产品的售价。

　　富士通公司在一份声明中说：“这项技术为无线充电技术与手机的整合铺平了道路，并使多种便携式电子产品不受其与充电系统的距离限制同时进行充电。”

　　现在，日本的手机用户可以使用一次性便携式充电器为电池充电。在大多数火车站和便利店都可以购买这种产品。但手机公司警告说，长期使用这种充电器可能对手机造成损害。

　　富士通公司还表示，希望将这项技术应用于便携式电子产品以外的领域，包括电路板或电脑芯片之间的电能传输，以及为电动汽车提供移动充电系统。
