摘要

本文介绍了一种数据驱动的锂离子电池建模方法,其中包括开路电压和充电状态的估算。利用所提出的方法,无需明确的理论模型,就能捕捉到电池单元的动态变化。这种方法只需要获取两个易于测量的变量:放电电流和端电压。获取的数据用于建立线性微分系统,通过代数处理形成电池单元的空间状态表示。由此产生的模型经过了测试,并与实际放电曲线进行了比较。初步结果表明,使用考虑恒定开路电压的模型,可以以有限的精度计算出电池的充电状态。为了提高确定模型的精确度,在数据驱动方法中采用了改进的递归最小二乘算法来估算电池的开路电压。最后的结果表明,该方法能非常精确地跟踪真实的电池放电动态,包括端电压和充电状态。所提出的数据驱动方法可以简化自适应控制策略在更大规模解决方案和多电池单元互联的电池管理系统中的实施。

Data-Driven Modeling and Open-Circuit Voltage Estimation of Lithium-Ion Batteries
This article presents a data-driven methodology for modeling lithium-ion batteries, which includes the estimation of the open-circuit voltage and state of charge. Using the proposed methodology, the dynamics of a battery cell can be captured without the need for explicit theoretical models. This approach only requires the acquisition of two easily measurable variables: the discharge current and the terminal voltage. The acquired data are used to build a linear differential system, which is algebraically manipulated to form a space-state representation of the battery cell. The resulting model was tested and compared against real discharging curves. Preliminary results showed that the battery’s state of charge can be computed with limited precision using a model that considers a constant open-circuit voltage. To improve the accuracy of the identified model, a modified recursive least-squares algorithm is implemented inside the data-driven method to estimate the battery’s open-circuit voltage. These last results showed a very precise tracking of the real battery discharging dynamics, including the terminal voltage and state of charge. The proposed data-driven methodology could simplify the implementation of adaptive control strategies in larger-scale solutions and battery management systems with the interconnection of multiple battery cells.
