Application: Battery module (Patent ID: US20240106028A1)
The patent filed by Samsung SDI Co Ltd describes a battery module that includes a series of cell stacks arranged in a module housing with receiving parts to accommodate the cell stacks. Each receiving part has a fixed wall with end walls that engage the cell stack surfaces. The module also includes a cooling channel below the floor surface of the housing for coolant flow to cool the cell stacks and receiving parts. Additionally, a cooling plate and coolant line are connected to the cooling channel to facilitate efficient cooling of the battery module.
The battery module further includes specific features such as a coupling part between adjacent modules, a cooling channel design with lateral walls and channel covers, and a separation wall within the module housing to partition the receiving parts. The end walls of the receiving parts are designed to create impact absorption spaces, and the cell stacks have end supports with ribs for structural support. The unique design elements of the battery module aim to enhance cooling efficiency, structural integrity, and overall performance of the battery system.
