摘要
随着电动汽车的设计、研发和推广,电池技术已然成为全球电动汽车行业发展的主要趋势。电动汽车因电池系统易受外界环境以及行驶工况的影响,动力电池散热系统极易发生出现电池系统过热或电池散热不良等现象。本文重点分析了金属锂离子材料动力电池的生热机理和空气传热控制规律,并选取18650型锂离子动力电池系统作为本文研究主要对象,深入研究了利用隔板改变冷却空气流道对该型动力电池及动力电池组风冷系统的散热控制效果并对其热管理性能进行优化分析。
With the development of electric vehicles,battery technology has become the main trend in the development of the global electric vehicle industry.Because the battery system of electric vehicles is easily affected by the external environment and driving conditions,the power battery cooling system is prone to overheating of the battery system or poor battery cooling.This paper focuses on the analysis of the heat generation mechanism and air heat transfer control law of the metal lithium-ion material power battery,and selects the 18650 lithium-ion battery system as the main object of this paper.The heat dissipation control effect of the power battery and the power battery pack air cooling system and the optimization analysis of its thermal management performance.
