本文对锂离子电池的12种等效电路模型进行了比较研究。这12个模型选自文献中报道的最先进的集总模型。所使用的测试数据是从具有气候室的电池测试系统获得的。测试计划的目的是测量高度动态激励下的关键细胞属性。数据集是从两种类型的锂离子电池在三个不同的温度下收集的。采用多群粒子群优化算法对两种锂离子电池的模型参数进行了优化辨识。然后通过将模型应用于从相同化学类型的其他细胞获得的数据集来检查模型复杂性、模型准确性和模型的鲁棒性，通过综合评估来研究这些模型的有用性。(C)2011 Elsevier BM. All rights reserved.
This paper presents a comparative study of twelve equivalent circuit models for Li-ion batteries. These twelve models were selected from state-of-the-art lumped models reported in the literature. The test data used is obtained from a battery test system with a climate chamber. The test schedule is designed to measure key cell attributes under highly dynamical excitations. The datasets were collected from two types of Li-ion cells under three different temperatures. The multi-swarm particle swarm optimization algorithm is used to identify the optimal model parameters for the two types of Li-ion cells. The usefulness of these models is then studied through a comprehensive evaluation by examining model complexity, model accuracy, and robustness of the model by applying the model to datasets obtained from other cells of the same chemistry type.
