Electronics cooling research has been largely focused on high heat flux removal from computer chips in the recent years. However, the equally important field of high-power electronic devices has been experiencing a major paradigm shift from air cooling to liquid cooling over the last decade. For example, multiple insulated-gate bipolar transistors (IGBT) used in a power drive for motor used in electric vehicle. Motor drive system plays an important impact on electric vehicle’ performance, so thermal design should be considered in the early stages during the motor controller design and layout of the devices. In this paper, a new type of water-cooled cold plate for motor controller was designed, and its cooling ability was analyzed by using different material base on Fluent. The results provide reference on the optimization design of cold plate.

Wire System

In order to improve performances of a virtual prototype, modeling and analysis are necessary before a system is produced and put into use. Firstly, structure and control schematics of electric vehicle with the steer by wire system and brake by wire system integrated are analyzed. Then, dynamics models of brake by wire system including the motor, planetary gear reducer, ball screw, etc. are built using Matlab software. Finally, effects of brake by wire system parameters such as motor parameters on system performance such as time domain and frequency domain response characteristics are analyzed using modern control theory. The results show that the modeling and analysis helps to find the performance sensitive parameters ,which will be used for parameter optimization design of brake by wire system.
