动力电池包的热管理系统仿真及其应用

Simulation and Application of Thermal Management System for Power Battery Pack

摘要: 由于动力电池包(电动大巴、电动轿车等应用情景)工作环境恶劣多变，影响电池充放电工作和使用寿命。为提高动力电池的利用率和使用安全等方面的考虑，进而进行动力电池包的热管理系统仿真及其应用。本文分别从系统原理构造，系统计算机仿真，实体实验等方面进行分析和研究，提出可行性方案，并进行相关的模拟工况实验，最终应用在动力电池包上。

Abstract: Because the working environment of power battery pack (electric bus, electric car, etc.) is bad and changeable, the battery charging and discharging work and service life are affected. In order to improve the utilization rate and safety of power battery, the thermal management system of power battery pack is simulated and applied. In this paper, the system principle, computer simulation, experiment and other aspects are analyzed and studied, feasibility scheme is put forward, and relevant simulation experiments are carried out and applied to power battery pack.
