中文摘要

锂离子电池是电动汽车供电的核心。准确预测电池剩余使用寿命(RUL)对于保障系统安全与可靠性至关重要。由于电池老化机制复杂,BMS进行RUL预测面临挑战。本文提出了一种基于新型退化指标的预测框架,结合分数阶灰色模型与无迹粒子滤波算法,有效提升了电池寿命预测的精度与鲁棒性。

English Abstract

The lithium-ion battery plays a crucial role in the power supply of the electric vehicles (EVs). Battery remaining useful life (RUL) is critically vital to ensure the vehicles' safety and reliability. Due to the complicated aging mechanism, predicting RUL for the battery management systems (BMSs) is challenging. In this article, a novel degradation indicator was constructed using the information e...
