摘要

本文主要研究一阶Randles模型对应频带的阻抗测量。提出了基于波德相图的电池荷电状态估计技术。阻抗相位特性的局部最小值的频率使得在寿命早期评估电池容量的损失成为可能。所提出的实验装置可作为现场阻抗测试仪的原型。

Impedance measurements for battery state of health monitoring

This work is devoted to impedance measurements in the frequency band corresponding to the Randles model of the first order. There was proposed the estimating technique of the battery SOC based on the Bode phase diagram. The frequency of the local minimum on the impedance phase characteristic makes it possible to assess the loss of the battery capacity at early stages of life. The proposed experimental setup may serve as a prototype for impedance testers in the field.
