摘要
针对大规模蓄电池组内阻测试中的旁流误差问题,提出一种阻抗因子的测试与计算方法,实验结果表明,利用该方法可以有效消除旁流误差,达到与离线测试一致的结果,从而有效提高蓄电池健康监测的准确度和效率.
In order to eliminate the bypass flow error during the measurement of the internal impedance of each battery cell within a battery pack system, we initially make measurements of two battery cells within each string to calculate the internal impedance of each battery cell and to calculate a common impedance multiplier term for the rest of the battery cells in each string. The results indicate that this method achieves consistent results with the off-line test and effectively eliminates the bypass flow error,which improves the accuracy and efficiency of the battery health monitoring.
