资料介绍

针对高压大功率锂离子蓄电池组单体电压信号变换问题,提出了三种实用型模拟电子电路方案,分别为线性光耦隔离法、直接采样法、非线性光耦实现模拟信号线性隔离法.对其原理与性能进行分析与实验,比较了优缺点,证明线性光耦隔离法既实现了电池与测量电路的隔离,又有精度高、调试简单等优点,性能优良,适用于串联单体数较多的情况.

Three practical analog electronics circuit schemes were proposed for the cell voltage signal transform of high voltage and power lithium-ion battery pack,including linear optical coupler isolation,direct sampling and nonlinear optical couplers realizing analog signal linear principles and performance of these schemes were analyzed and comparing the advantages and disadvantages,scheme including linear optical coupler isolation can isolate cells and testing h precision and simple debugging process can be suits for the situation of series connection of large number of cells.
