基于参数关联矩阵的电子控制模块健康状态评估方法
By constructing a parameter correlation matrix and using bus current and voltage data to calculate transient characteristics, the dynamic impedance evolution inside the electronic control module is identified. This solves the problem that existing technologies cannot identify microsecond-level transient disturbances in energy storage units, and enables accurate assessment of module health status and elimination of potential risks.

Abstract
本发明涉及电路装置监控技术领域，公开了一种基于参数关联矩阵的电子控制模块健康状态评估方法，包括：获取充电阶段的母线电流、母线电压及能量变化序列，计算瞬态功率相对于电压平方的导数响应轨迹；将该导数响应轨迹映射至包含功率、电压及充放电时序参数的多维参数空间，构建反映储能单元内部动态阻抗演进过程的参数关联矩阵；通过计算实测轨迹与标准健康轨迹的曲率特征差异来确定特性缺陷，本发明基于能量转换维度的归一化处理，有效隔离电源纹波对阻抗特征提取的干扰，能够精准识别由封装微裂纹或焊点空洞诱发的隐性故障，建立起覆盖模块全寿命周期的数字化健康评价基准。
