Thermal management of an electrochemical cell by a combination of heat transfer fluid and phase change material

摘要

The invention is directed at devices, systems, and processes for managing the temperature of an electrochemical call including a device 10 comprising an inlet for receiving a heat transfer fluid; one or more electrochemical cell compartments 12 for receiving one or more electrochemical calls 20; one or more thermal energy storage material compartments 14 containing one or more thermal energy storage materials 18; and one or more heat transfer fluid compartments 16 for flowing the heat transfer fluid through the device; wherein the space between the one or more heat transfer fluid compartments 16 and the one or more electrochemical cell compartments 12 preferably includes one or more first regions 22 (i.e. portion) that are substantially free of the thermal energy storage material 18; and the space between the one or more heat transfer fluid compartments 16 and the one or more thermal energy storage material compartments 14 preferably includes one or more second regions 24 (i.e. portion) that are substantially free of an electrochemical cell 20; so that the heat transfer fluid compartment 16 is in direct thermal communication with both the thermal energy storage material compartment 14 and the electrochemical cell compartment 12.
