考虑实际工况的锂离子电池增量容量曲线确定方法对比研究

Comparative Study of Incremental Capacity Curve Determination Methods for Lithium-Ion Batteries Considering the Real-World Situation

语言:

中文摘要

增量容量分析(ICA)是电池健康状态(SOH)评估的关键技术,但电动汽车在实际运行中充电条件不确定且数据不完整,限制了增量容量(IC)曲线的提取。本文针对真实工况下的IC曲线确定方法进行了深入对比分析,旨在提升复杂环境下电池状态评估的准确性与鲁棒性。

English Abstract

The incremental capacity analysis (ICA) method is a promising method in battery state of health (SOH) estimation studies. The incremental capacity (IC) curve determination is one of the critical parts of the ICA method. However, the uncertain and incomplete charging conditions of real-world electric vehicles (EVs) significantly limit the IC curve determination. This article provides a thorough ana...
