The state of health (SOH) estimation for sodium-ion batteries is crucial for their safe and efficient applications, which is also a key to large-scale energy storage implementations. However, sodium-ion batteries exhibit usage-induced degradation with unclear mechanisms and are sensitive to operating conditions and environmental factors, posing a challenge to the accurate SOH estimation. In this paper, a data-driven SOH estimation method for sodium-ion batteries is proposed. The charging data is correlated with capacity degradation, and variance filtering, grey relational analysis and recursive feature elimination are integrated for feature selection. In addition, four machine learning methods including multiple linear regression, support vector machine, Gaussian process regression and error back propagation neural network are applied to formulate the corresponding estimation methods. Test results reveal that the root mean square errors for the four methods are all less than 1.6%, with Gaussian process regression showing an error rate below 0.8%, indicating a precise SOH estimation for sodium-ion batteries.

钠离子电池健康状态估计是其安全高效应用的基础,也是钠电池规模化储能应用的关键。然而,钠离子电池即用即衰,衰退机理不明晰,老化过程受工况和场景影响,准确的健康状态估计极其困难。为此,提出了数据驱动的钠离子电池健康状态估计方法,探究了钠离子电池的充电数据与容量衰退的映射关系,提出了结合方差筛选、灰色关联分析和递归特征消除的特征选择方法,应用多元线性回归、支持向量机、高斯过程回归和误差反向传播神经网络4类机器学习方法估计钠离子电池的健康状态。验证结果表明,4类方法的健康状态估计均方根误差小于1.6%,其中高斯过程回归的误差小于0.8%,实现了钠离子电池健康状态精准估计。
