Design optimization of liquid cooling system for titanium-based supercapacitor module in ultra high power scenarios of frequency regulation energy storage system
Abstract：The ultra high power characteristic of frequency regulation energy storage system poses severe challenges to the design of thermal management system. Based on numerical simulation technology, this study aims to minimize the temperature rise and temperature difference between the battery cells of titanium-based supercapacitor module. This study analyzes the effects of variables such as the number of coolant channels, channel layout, and channel width on the cooling performance of liquid cooling system under ultra high constant power conditions of 8 times the rated power (8P). Based on this, a liquid cooling plate is designed and optimized. This liquid cooling plate can achieve a maximum temperature difference of only 2.8 K between the battery cells of titanium-based super- capacitor module under continuous charging and discharging conditions at 8 times the rated power.
