Battery pack housing

Cooling battery housing that induces turbulence through electrode tab-accommodating protrusions and inter-module grooves

This technology features a structural design that incorporates protrusions and grooves within the housing, aligned with the anode and cathode tabs of battery modules. It increases the velocity and flow rate of the cooling fluid and generates turbulence to efficiently cool localized heat around the tabs.

Electrode tabs in battery modules are prone to heat concentration during charging and discharging. Conventional cooling fluid injection methods failed to account for these localized heat characteristics, resulting in low cooling efficiency and temperature deviations between cells.

This technology utilizes protrusions within the housing to accommodate electrode tabs, forcing the cooling fluid to strike them, while grooves acting as partitions are placed between modules to push the fluid upward. These structures are arranged alternately along the flow direction. Applicable to EV battery packs, immersion-cooled ESS racks, and high-power tool packs, it resolves heat concentration at the tabs and ensures temperature uniformity across cells.

Key Features:

• An internal space accommodating a plurality of battery modules, each equipped with anode and cathode tabs, in a spaced-apart configuration
• A plurality of protrusions extending from the internal space to accommodate the electrode tabs of the battery modules, with one side facing the direction of cooling fluid flow
• One or more grooves formed from the bottom surface toward the internal space and positioned between the battery modules
• A fluid inlet and a fluid outlet provided on one side and the other side of the housing, respectively, for the inflow and outflow of cooling fluid
