摘　　要：介绍一种采用普通数字光耦实现了蓄电池组的每一节单体电池电压的无源耦合,利用软件二次曲线补偿的方法解决了因普通数字光耦的信号耦合引起的非线性问题,利用线性光耦对电池组整体电压进行采样,可以计算出电池每伏电压的补偿量,从而解决了普通数字光耦的温度漂移,为实际工程应用提供了一种可行的方案。Introduce a scheme of solveing the temperature drift of ordinary digital optocoupler ,The process as follows. Adopting ordinary digital optocoupler achieves passive coupling about the voltage of per haploid batteries which belongs to accumulator battery. The nonlinear signal coupling problem is solved by the conic compensation of software. The voltage of the battery bank is sampled by linear optocoupler. Through the upper steps, we can calculate the compensation rate of the per voltage, In order to solve a common digital optocoupler temperature drift,the scheme provides the feasibility of actual projects.
