摘要

锂离子电池(LiBs)已成为电动汽车(ev)等应用的主要储能化学材料。用于电池管理系统(BMS)在线运行的锂离子电池的高保真物理模型尚未实现，并且正在进行研究。提出了一种利用有限体积法和欧拉法实现LiB伪二维(P2D)模型的新算法。我们提出的方法使用了一种新颖的寻根算法，该算法以与市售求解器相同的精度求解P2D模型，但求解速度要快得多，使我们的方法适用于实时应用。

A Novel Root-Finding Algorithm to Solve the Pseudo-2D Model of a Lithium-ion Battery

Lithium-ion Batteries (LiBs) have become the main energy storage chemistry for applications like electric vehicles (EVs). High-fidelity physics model of LiBs for online operation of a battery management system (BMS) is yet to be achieved and is ongoing research. In this paper, a novel algorithm is proposed to implement a pseudo-two-dimensional (P2D) model of a LiB using the Finite Volume and Euler Methods. Our proposed approach uses a novel root-finding algorithm that solves the P2D model with the same degree of accuracy as commercially available solvers but with much faster solving speeds, making our approach suitable for real-time applications.
