摘要
在中国大学生电动方程式大赛(简称FSEC)中,动力电池箱作为赛车的核心,其内部的结构布置与整体设计尤为重要。在选取新箱体材料的基础上,利用Simulink对赛车进行动力系统仿真确定电池模组容量,然后用CATIA对赛车动力电池箱内部各部件进行精确建模,并且通过ANSYS对电池箱产热散热进行分析,最后再利用CATIA电池箱进行整体设计并优化内部布置。并对成品电池箱进行强度、散热、动力性、耐久性等试验测试,验证了设计的有效性。通过以上过程在确保动力电池系统的散热效率及可靠性和安全性的基础上,改进了动力电池箱内部结构的布局使得动力电池箱的空间利用率大大提高,电池包成组效率达到了0.723,实现了对动力电池包乃至整车的轻量化设计。
In Formula Student Electric China(referred to as FSEC),the power battery box is the core of the car and its internal structural layout and design are very important.Based on selecting the new box material,Simulink was used to simulate the power system of the racing car to determine the capacity of the battery module,followed by the use of CATIA to accurately model the internal components of the racing car power battery box and to analyze the heat generation and heat dissipation of the battery box through ANSYS.Finally,CATIA battery box was manipulated to carry out the overall design and optimize the internal layout.The strength,heat dissipation,power,and durability of the finished battery box were tested to verify the effectiveness of the design.Based on ensuring the heat dissipation efficiency,reliability,and safety of the power battery system,the layout of the internal structure of the power battery box are improved through exploiting the above procedures so that the space utilization rate of the power battery box is greatly improved and the group efficiency of the battery pack reaches 0.723;realizing the lightweight design of the power battery pack and even the whole vehicle.
