　　先进的集成电路简化了锂离子电池充电测量的精确状态

　　所有能源收集系统需要能源储存的时候，能量无法得到（例如，在夜间为太阳能供电系统）。可充电电池——通常称为“次级电池”，以区别于原电池或单用电池，通常是为这项任务指定的。

　　然而，对于可充电电池，电池管理依赖于电池电池充电状态（SOC）的最佳测量。对于锂离子电池来说，李离子电池的特性使SOC测量复杂化，可以挑战锂离子电池寿命最大化的工程师。为了简化锂离子电池管理系统的设计，工程师可以利用各种SOC测量技术在集成电路从ATMEL，支持线性技术，集成产品，意法半导体，德克萨斯文书。

　　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.
