Abstract

This article presents an integrated control strategy for optimal fast charging and active thermal management of lithium-ion batteries (LiBs) in extreme ambient temperatures, striking a balance between charging speed and battery health. A control-oriented thermal-nonlinear double-capacitor (NDC) battery model is proposed to describe the electrical and thermal dynamics, incorporating the effects of both an active thermal source and ambient temperature. A state-feedback model predictive control (MPC) algorithm is then developed for optimal fast charging and active thermal management. Numerical experiments validate the algorithm under extreme temperatures, showing that the proposed algorithm can energy-efficiently adjust the battery temperature, thereby balancing charging speed and battery health. In addition, an output-feedback MPC algorithm with an extended Kalman filter (EKF) is proposed for battery charging when states are partially measurable. Numerical experiments validate the effectiveness under extreme temperatures.

锂离子电池在极端环境温度下的集成优化快速充电和主动热管理

本文提出了一种锂离子电池在极端环境温度下优化快速充电和主动热管理的集成控制策略，在充电速度和电池健康之间取得平衡。提出了一种面向控制的热非线性双电容（NDC）电池模型来描述电池的电动力学和热动力学，同时考虑了主动热源和环境温度的影响。然后提出了一种状态反馈模型预测控制（MPC）算法，用于优化快速充电和主动热管理。在极端温度下的数值实验验证了该算法的有效性，结果表明该算法能够高效地调节电池温度，从而平衡充电速度和电池健康。此外，针对电池充电状态部分可测的情况，提出了一种带扩展卡尔曼滤波（EKF）的输出反馈MPC算法。数值实验验证了该方法在极端温度下的有效性。

期刊介绍： The IEEE Transactions on Control Systems Technology publishes high quality technical papers on technological advances in control engineering. The word technology is from the Greek technologia. The modern meaning is a scientific method to achieve a practical purpose. Control Systems Technology includes all aspects of control engineering needed to implement practical control systems, from analysis and design, through simulation and hardware. A primary purpose of the IEEE Transactions on Control Systems Technology is to have an archival publication which will bridge the gap between theory and practice. Papers are published in the IEEE Transactions on Control System Technology which disclose significant new knowledge, exploratory developments, or practical applications in all aspects of technology needed to implement control systems, from analysis and design through simulation, and hardware.
