Battery pack

Abstract

A battery pack includes a battery module (3010), which includes a liquid-limiting housing (0080) formed in a tubular structure and at least one battery holder (0050). The liquid-limiting housing (0080) has a battery holder stop structure (0140) protruding from an inner wall surface (0101) to limit vertical movement of the battery holder (0050). The liquid-limiting housing (0080) further includes a battery holder fixing structure (0150) to structurally limit displacement in each direction by fasteners (0152), thereby ensuring that the battery holder (0050) and the battery cell (0020) can be securely held in an immersion environment from all directions. The inner wall surface (0101) may be formed to conform to the curvature of the battery cell (0020) to reduce the module volume. A battery pack includes a battery module (3010) comprising a liquid-limiting casing (0080) configured as a tubing structure and at least one cell holder (0050). The liquid-limiting casing (0080) features a cell-holder stopping structure (0140) protruding from an inner wall surface (0101) to restrict vertical movement of the cell holder (0050). The liquid-limiting casing (0080) further comprises a cell-holder fixing structure (0150) that is configured to mechanically limit displacement in every direction via a fixing fastener (0152). This combination ensures robust, omni-directional retention of the cell holder (0050) and the plurality of battery cells (0020) within the immersion environment. Inner wall surfaces (0101) may be formed as curved surfaces conforming to the battery cells (0020) to reduce module volume.
