Abstract
本发明涉及一种电池安全态势感知及老化状态估计方法及系统。方法包括：获取电池运行过程中的多维运行数据，包括电池温度数据、电流数据、电压数据、荷电状态和冷却工况参数；从多维运行数据中识别运行片段并对其进行可辨识性判定，评估运行片段中的温度响应对电池内部产热参数的敏感程度；将可辨识运行片段输入至预先训练好的温度响应代理模型，反演得到电池当前包括熵热系数在内的产热机理参数；构建安全态势特征向量，计算安全态势指数；基于产热机理参数，结合老化参数数据库，评估电池老化状态。本发明充分利用现有BMS采集的数据，无需增加额外硬件成本，实现了基于电热机理约束的老化状态在线估计，兼具实时性与物理可解释性。
