中文摘要

针对电动汽车传感器因振动或连接松动导致数据采集异常的问题,本文提出了一种基于双向机制的状态估计方法。该方法在输入数据缺失的情况下,仍能实现对锂离子电池荷电状态(SOC)的准确监测与诊断,提升了储能系统在复杂工况下的运行可靠性。

English Abstract

Accurate states monitoring and timely diagnosis of energy storage device for electric vehicles are important, and they depend on the data collected by a large number of sensors. High-frequency vibration and loose connectors make the local sensors fail in the long term, which causes the abnormal collection of data and states monitoring. In this article, a state estimation method based on the bidire...
