Modern high-capacity lithium-ion battery systems rely on efficient liquid-cooling systems to maintain their safe operating temperature range under all conditions.
Among several technical solutions to provide the cooling for battery cells large brazed aluminium cooling plates have gained wide acceptance due to their balance of efficiency and cost.
The aluminium industry provides a wide range of material solutions for the manufacturing of brazed battery cooling plates from cost efficient standard materials to advanced high strength materials. In this paper the requirements for materials are discussed and a guideline for the material selection is given.
