ENERGY STORAGE THERMAL MANAGEMENT SYSTEM USING MULTI-TEMPERATURE PHASE CHANGE MATERIALS

摘要

A thermal management method and system for energy storage devices, such as devices including an array of electro-chemical cell elements. A first phase change material is in heat-transferring thermal contact with the electrochemical cell elements. A second phase change material in heat-transferring thermal contact with the first phase change material. A heat exchange path can be disposed between the first phase change material and the second phase change material.
