Abstract: Presented are thermal management systems using coolant flow distribution plates for immersion cooling of battery cells, methods for making/using such systems, and vehicles equipped with such systems for cooling the vehicles' battery packs. A battery assembly includes multiple battery cells arranged in adjacent, mutually parallel cell rows. The battery cells are stored inside a protective battery housing that includes inlet and outlet fluid ports for receiving and evacuating therethrough dielectric coolant fluid. A pair of (first and second) separator plates is located between each neighboring pair of cell rows. Each plate includes coolant channels that are arranged in mutually parallel channel bands. The separator plates are in face-to-face contact with each other such that each channel band of the first separator plate is aligned with a respective channel band of the second plate so the coolant channels cooperatively distribute coolant fluid onto and vertically upward between the battery cells.
