摘要

在电动汽车中，布线系统的作用对于电驱动的正确性能至关重要。电力的传输和机载系统的功能取决于所使用电缆的正确选择，这可以减少瞬态过电压和绝缘的快速老化。电缆尺寸的一个重要方面是确定和验证电容量，它受到许多因素的影响，如温度、安装和电压供应类型。本文分析了电池储能系统放电阶段由DC-DC变换器引入的电流波纹的热效应。采用基于磁有限元和热有限元的数值分析方法对电缆的性能进行了分析。

Thermal Analysis of Battery Cables for Electric Vehicles

The role of wiring system in an electric vehicle is very important for the correct performance of electrical drives. The transmission of power and the functionality of the onboard systems depend by the correct choice of the cables used, which permits to reduce the overvoltage during the transient and the rapid ageing of the insulations. An important aspect in cable sizing is the determination and verification of ampacity, which is influenced by many factors as the temperature, the installation, and the type of voltage supply. In the paper are analyzed the thermal effects of current ripples introduced by the DC-DC converter during the discharge phase of the battery storage system. A numerical approach based on magnetic and thermal finite element analysis is used with the aim to analyze the cable performance.
