中文摘要

锂离子电池广泛应用于储能系统(BESS)和电动汽车。数据驱动方法通过测量特征估计电池健康状态(SOH),但过多特征会降低精度并增加人工成本。本文提出了一种多目标优化方法,旨在通过精简特征集提升SOH估计的准确性与效率。

English Abstract

As a favorable energy storage component, lithium-ion (Li-ion) battery has been widely used in the battery energy storage systems (BESS) and electric vehicles (EV). Data driven methods estimate the battery state-of-health (SOH) with the features extracted from the measurement. However, excessive features may reduce the estimation accuracy and also increases the human labor in the lab. By proposing ...
