摘要

摘要: 以某电动汽车电池模组为对象，研究了模组放电倍率、汇流排接触面积和电流I/O位置等设计参数对模组温度场电场的影响。通过对温度场分布的分析，考察了设计参数对电池单体和汇流排的温度变化、温度的均匀性以及二者之间热交换情况的影响。研究表明：电流放电倍率不仅对温升影响较大，还会影响汇流排和电池单体之间的热交换，高倍率电流充放工况下电池发热应该考虑汇流排电热效应的影响。接触面积和电流I/O位置会对电池单体温升、度均衡性以及电流均衡性产生不同程度的影响。

Abstract: Taking the battery module of an electric vehicle with bus-bar as the research object, the effects of the design parameters such as the electric-discharge magnification, the bus-bar contact area and the current I/O position on the electric field and the temperature field of module are studied. Based on the analysis of the temperature field distribution, the influence in the battery monomer and the bus-bar of the design parameters on the temperature change, the uniformity of the temperature and the heat exchange between the two groups were investigated. The results show that the current discharge magnification not only affects the temperature rise, but also the heat exchange between the bus-bar and the cell. Therefore, the heat of the bus-bar on the effect of a cell should be taken into account in the high current charge-discharge conditions. The contact area and position of current I/O will have different effects on battery temperature rise, temperature balance and current balance.
