能量收集技術(shù)延長(zhǎng)電池壽命

　　消費(fèi)者對(duì)移動(dòng)電子產(chǎn)品的愿望進(jìn)行了長(zhǎng)期的電池壽命的默認(rèn)期望，無(wú)論任何功能增強(qiáng)。能量收集技術(shù)可以幫助工程師大大延長(zhǎng)原電池的壽命。對(duì)于設(shè)計(jì)師來(lái)說(shuō)，建立電池?cái)U(kuò)展電路的任務(wù)已經(jīng)從模擬設(shè)備，Cymbet，線性技術(shù)的專(zhuān)業(yè)集成電路的可用性變得相當(dāng)方便，德克薩斯文書(shū)，其中。

　　能量收集提供了一種手段，使許多應(yīng)用嚴(yán)格地從環(huán)境能源，包括太陽(yáng)能，溫差，振動(dòng)或射頻能量。對(duì)于這些“零功率”的設(shè)計(jì)，可用的環(huán)境能源超過(guò)設(shè)計(jì)功耗的要求-通常是因?yàn)閼?yīng)用程序帶來(lái)了最小的功能要求很容易滿足使用超低功耗元件。

　　For other applications， however， more complex application requirements can tip the power generation/consumption ratio away from zero-power solutions and instead dictate a need for one or more primary batteries. Even in these cases， designers can nevertheless find themselves facing a growing gap between power requirements and total-battery capacity. When the gap grows too large， consumers become dissatisfied with the product， perceiving it as too frequently requiring battery replacement or recharging.
