Key Features to Look for in EV Battery Cell Cold Plates
What Are the Key Features to Look for in EV Battery Cell Cold Plates? Electric vehicles (EVs) are rapidly transforming the automotive landscape, with the efficiency and reliability of their batteries playing a pivotal role in this evolution. A critical component in maintaining the optimal performance of EV batteries is the cooling system, particularly the cold plates that manage thermal regulation. Choosing the right EV battery cell cold plate is essential for ensuring safety, performance, and longevity. In this article, we’ll explore the key features purchase managers and engineers should consider when selecting EV battery cell cold plates. Hydroformed cooling plates are widely preferred in the automotive industry due to their optimal balance between cost and mechanical strength, making them suitable for mass production. Key features include high thermal conductivity, strong material durability, and corrosion resistance, which ensure efficient heat transfer and long-term reliability in EV battery applications. Table of Contents Understanding Stamping Type Liquid Cooling Plates Definition and Overview Hydroforming cold plate means those plate manufactured using stamping processes, where thin metal sheets are formed into desired shapes and features through the application of high pressure. The stamping process enables the creation of intricate channels within the plate, through which a liquid coolant flows to absorb and dissipate heat away from the components. Material Selection One of the defining characteristics of stamping type liquid cooling plates is the material used in their construction. Typically, aluminum and copper are the materials of choice due to their excellent thermal conductivity. Aluminum is favored for its lightweight nature, corrosion resistance, and lower cost, making it suitable for automotive and consumer electronics applications. Copper, on the other hand, offers superior thermal performance but is heavier and more expensive, often reserved for high-performance or specialized applications. The choice of material directly impacts the cooling plate’s…
