Deep Dive into the Hyundai Ioniq 5 Battery Pack

🔋The Hyundai Ioniq 5 battery pack features an integrated cold plate for efficient cooling.

🔩The pack utilizes aluminum extrusion and rivnuts to secure the lid, providing a service-friendly design.

🧲A large injection-molded seal with compression limiters is used to seal the pack, allowing for pressure relief in case of thermal venting.

💦The pack does not have internal coolant runs, simplifying module removal but requiring thermal interface material for heat dissipation.

⚙️The pack's construction and sealing methods strike a balance between cost, serviceability, and safety considerations.

Why does the pack use an integrated cold plate?

—The integrated cold plate allows for efficient cooling of the battery pack, ensuring optimal performance and longevity.

What is the advantage of using rivnuts for securing the lid?

—Rivnuts provide a service-friendly design, allowing for easy lid removal and access to the pack's components.

Why is a large injection-molded seal used for sealing the pack?

—The seal is costlier but provides an effective method for pressure relief in case of thermal venting, enhancing safety.

Why is thermal interface material necessary in the pack?

—The pack does not have internal coolant runs, so thermal interface material is used to transfer heat from the modules to the pack's base for dissipation.

What factors were considered in the pack's construction and sealing methods?

—The construction and sealing methods aim to balance cost, serviceability, and safety, incorporating features like service access panels and thermal venting strategies.
