<br /><br />如果您繪制能力在主場(chǎng)迎戰(zhàn)改變電壓的變化，您會(huì)獲得一個(gè)高峰代表在放電容量（50姊空）與代表的能力，每單元的電壓變化量斜坡，中點(diǎn)。對(duì)于手機(jī)使用的鋰離子電池為例，在洪峰流量的能力，正值約3.6伏特。 <br /><br />但是，更高的高峰，更大的每單位電池的電壓變化的能力。換句話說(shuō)，更大容量的變化，將電池放電速度更快。如果你壓扁的斜率（和較低的峰值），它可能只出現(xiàn)您已降低您的，說(shuō)的能力，3.6或3.5五 <br /><br />但減少排放率，您可能會(huì)增加，比如說(shuō)電池的能量提供給您，2.8，2.5，甚至2五 <br /><br />為什么重要？ <br />對(duì)于系統(tǒng)，以此作為對(duì)充電電池狀態(tài)指示燈電池電壓，在閱讀過(guò)程中的電池電壓放電小錯(cuò)誤可能導(dǎo)致大的錯(cuò)誤估計(jì)能力。此外，山頂向下移動(dòng)的排氣溫度降低。 <br /><br />因此，系統(tǒng)運(yùn)行時(shí)間將在較低的溫度大大縮短，但仍然有一個(gè)很大的電池容量可供操作的制度，雖然在較低的電壓。 <br /><br /><br />這個(gè)問(wèn)題的一種解決方案是有一個(gè)自適應(yīng)功率拓?fù)浠A(chǔ)上的鋰離子電池的剩余容量低電池截止，并能允許放電電壓低于典型的3 - 或3.3V fixed cutoff電壓。 <br /><br />使用此方案，系統(tǒng)運(yùn)行時(shí)可以更對(duì)cell' s循環(huán)壽命和不同的使用溫度可預(yù)測(cè)的。 <br /><br />對(duì)于許多消費(fèi)電子產(chǎn)品，這種解決方案將允許在各種環(huán)境中的使用更加一致的行動(dòng)和對(duì)系統(tǒng)的壽命。這是特別有用，在系統(tǒng)的電池是不太可能被刪除或如移動(dòng)電話或MP3播放器定期更換。 <br /></p>本文引用地址：<a
