Application of Lithium-ion Battery Power Metering Method in Cochlear Speech Processor

锂离子电池的可用剩余容量是电池管理系统(BMS)中的一个重要参数,针对基本恒流放电的系统,为相对精确的计算出电池的可用剩余容量,提出了一种新型的估算锂离子电池可用剩余容量的方法,利用电池电压查表法和库仑计(coulomb count)方法结合估测电池的SoC,得到锂离子电池SoC的估测值。通过本方法可以很好的相对精准的以百分比的显示方法预测锂离子电池的剩余容量。

Lithium ion battery remaining capacity are available battery management system （BMS）, one of the important parameters for the basic constant exile electric system, for a relatively accurate to calculate the residual capacity of battery is available. This paper proposes a new method of estimating the residual capacity of lithium ion battery available, using the battery voltage look-up table method and the coulombmeter （coulomb count） method combined with estimates of the SoC of the battery, and getting the lithium ion battery SoC estimation value. By this method, the residual capacity of lithium ion batteries can be predicted accurately and accurately.
