Hafiz M. Usman, Shayok Mukhopadhyay, Habibur Rehman

摘要:

提出了一种基于通用自适应稳定器(UAS)的400 V锂离子电池组参数在线估计方法。电池开路电压、建模瞬态响应的参数和串联电阻都在单个实时测试中估计。与早期基于单个电池组的UAS工作相比,这项工作不需要事先进行离线实验或任何后处理。以最小的实验努力实时快速收敛参数的估计,使得能够在运行时自我更新电池参数。所提出的策略进行了数学验证,并证明其性能上的400 V,6.6 Ah的锂离子电池组供电的感应电机驱动的原型电动汽车(EV)牵引系统。

英文摘要:

This paper proposes an accurate and efficient Universal Adaptive Stabilizer (UAS) based online parameters estimation technique for a 400 V Li-ion battery bank. The battery open circuit voltage, parameters modeling the transient response, and series resistance are all estimated in a single real-time test. In contrast to earlier UAS based work on individual battery packs, this work does not require prior offline experimentation or any post-processing. Real time fast convergence of parameters' estimates with minimal experimental effort enables self-update of battery parameters in run-time. The proposed strategy is mathematically validated and its performance is demonstrated on a 400 V, 6.6 Ah Li-ion battery bank powering the induction motor driven prototype electric vehicle (EV) traction system.
