The forecast of IPhone 5 join solar charging function is concreted gradually. According to the data released by the United States Patent and Trademark Office, Apple has obtained a patent named portable device with multiple power interfaces for its fourth term solar energy patent. Which display that Apple is positive development in the solar energy supply of mobile device technology.
According to news reports, Apple is proposed the Numbers 7868582 of the patent in February 2009. The patent points out that the focus of this invention is the battery charging technology for mobile devices. Through a voltage converter, integration of the use of various of power sources, including solar energy.
The patent also points out that this battery charging technology can be used in the media player, notebook computer, tablet computer, mobile phone, image processing device and handheld operation device. This also sparked speculation that the future apple products will be fully equipped with solar charging function.
According to AppleInsider website reported that apple proposed this patent with the same name in 2006. But it has not been approved by the case. Apple proposed the patent with the same name in 2009 for approve.
The website of Intellectual property reports that Apple’s previously patent application is not successful, mainly because of the patent is similar with a solar charging battery holster and a solar connecting wire. But Apple finally has the patent due to the use of plug and play function, which has distinguished with the use of the device to adjust the power characteristics.
According to the content of the patent, we analyze and judge that the flexible film material will be used to meet the requirements of the mobile and portable device. As far as consider the anti-impact performance, we cannot sure which can be used at this time between metal substrate and plastic substrate.
Consider with the conversion rate of the solar cell, which is most possibly serve as the auxiliary power supply system and conform to the patent.
