为解决锂离子电池剩余容量预测中非线性特征提取不足、参数寻优易陷入局部最优、预测精度偏低的问题,提升电池健康管理的可靠性,本文提出混沌步长粒子群(CSPSO)优化多核支持向量机的电池容量预测算法,构建拉普拉斯核函数与径向基函数(RBF)核函数融合的多核SVM 模型,利用CSPSO算法实现模型关键参数全局寻优,采用均方误差倒数法自适应分配核函数子模型权重。结果表明:相较于传统PSO多核SVM预测方法,混沌步长粒子群算法凭借混沌动态调整学习因子与步长的特性,有效避免陷入局部最优,提升参数寻优精度。相较于单一核SVM预测方法,拉普拉斯核凭借适配高维稀疏数据的特性,可精准捕捉电池退化全局特征,RBF核凭借对局部非线性波动敏感的特性,可高效拟合容量衰减局部规律,二者融合大幅提升非线性特征提取能力。均方误差倒数法具备自适应权重分配的特点,避免等权重融合带来的性能平均化缺陷,提升模型整体预测精度与鲁棒性。CSPSO优化多核支持向量机的容量预测算法可有效提取电池退化多维非线性特征,参数寻优精度高、预测结果稳定,为锂离子电池剩余容量精准预测与健康状态管理提供了一种可靠的新途径。
To address the problems of insufficient nonlinear feature extraction
susseptibility to local optimum trapping in parameter optimization and low prediction accuracy in lithium-ion battery remaining capacity prediction
and improve the reliability of battery health management
this paper proposes a battery capacity prediction algorithm based on multi-kernel support vector machine (SVM) optimized by chaotic step particle swarm optimization (CSPSO). A multi-kernel SVM model integrating Laplacian kernel and radial basis function (RBF) kernel is constructed. The CSPSO algorithm is adopted for global optimization of key model parameters
and the reciprocal mean square error method is used to adaptively assign weights to sub-models of kernel functions. The results show that
compared with the traditional PSO-based multi-kernel SVM prediction method
CSPSO dynamically adjusts learning factors and step sizes via chaos theory
which effectively avoids local optima and improves parameter optimization accuracy. In contrast to single-kernel SVM
the Laplacian kernel adapts well to high-dimensional sparse data and accurately captures global battery degradation characteristics
while the RBF kernel is sensitive to local nonlinear fluctuations and efficiently fits local capacity fading rules. The fusion of the two kernels greatly enhances nonlinear feature extraction capability. The reciprocal mean square error method realizes adaptive weight allocation
eliminates the performance averaging defect caused by equal-weight fusion
and boosts the overall prediction accuracy and robustness of the model. The proposed CSPSO-optimized multi-kernel SVM capacity prediction algorithm can effectively extract multi-dimensional and nonlinear battery degradation features with high parameter optimization precision and stable prediction performance. It provides a novel and reliable approach for accurate remaining capacity prediction and health state management of lithium-ion batteries.
