| 摘 要： | 分析了锂离子电池组的电流采样误差较大的原因,并通过电压叠加电路的设计来解决充放电电流的区分问题。对电流采样值进行了分段插值方法校正,并对温度进行了直线校正。实验证明:校正后的电流值最大误差为0.02 A。

| Abstract: | The reason of large errors in current sampling of Li-ion batteries was analyzed.The problem of distinguishing charge-discharge current was resolved by the voltage superposition circuit design.The value of current sampling was corrected by the subsection interpolation method,and temperature was corrected by the linear correction.The tests demonstrated that the maximum error of the corrected current value was 0.02 A. |
