先進的集成電路簡化了鋰離子電池充電測量的精確狀態(tài)

　　所有能源收集系統(tǒng)需要能源儲存的時候，能量無法得到（例如，在夜間為太陽能供電系統(tǒng)）。可充電電池——通常稱為“次級電池”，以區(qū)別于原電池或單用電池，通常是為這項任務(wù)指定的。

　　然而，對于可充電電池，電池管理依賴于電池電池充電狀態(tài)（SOC）的最佳測量。對于鋰離子電池來說，李離子電池的特性使SOC測量復(fù)雜化，可以挑戰(zhàn)鋰離子電池壽命最大化的工程師。為了簡化鋰離子電池管理系統(tǒng)的設(shè)計，工程師可以利用各種SOC測量技術(shù)在集成電路從ATMEL，支持線性技術(shù)，集成產(chǎn)品，意法半導(dǎo)體，德克薩斯文書。

　　Battery SOC is defined as the percentage of charge remaining in a battery， and thus ranges from 0% to 100%. Because SOC measurement fills the same purpose as a gas gauge in an automobile， ICs that provide SOC measurement are typically called “gas gauge” or “fuel gauge” ICs.

　　SOC measurement underlines intelligent battery management systems. As SOC changes， battery management systems calculate optimum charging voltage and current values. Consequently， SOC measurement ICs are typically paired with battery charger ICs in designs or included as functionality within more comprehensive charge management and battery protection designs.
