Optimizing Thermal Management of Battery Systems in Electric Vehicles
Power storage engineers place high priority on finding solutions that optimize the safety and lifetime performance of a battery, while also increasing production efficiency and minimizing costs. Thermal Interface Materials (TIMs) and Thermally Conductive Adhesives (TCAs) make important contributions to these areas of vehicle design and production.
Battery systems account for approximately 20 percent of the weight of an electric vehicle, and as much as 50 percent of the cost. These factors are causing OEMs and Tier 1 suppliers to place a laser-sharp focus on getting the maximum possible value from batteries. Thermal management is a key factor in their efforts to achieve this, because it is vital to dissipate the heat produced by battery cells within battery packs efficiently. This requires highly conductive materials that fill the air gaps between elements within the battery. There are a variety of solutions available that can improve heat transfer from the battery cell modules to the cooling plate, and engineers are seeking to identify the most effective and cost-efficient solution, or combination of solutions, for their unique design or assembly process. This article focuses on two of these solutions: Thermal Interface Materials (TIMs) and Thermally Conductive Adhesives (TCAs).
