Protective structure for pouch cell battery

Abstract

A protective structure for a pouch cell battery, comprising a base 30, a top cover 50, and two terminal covers 50. The base supports a battery cell module, the top cover is connected to the base, and

Claims

A protective structure for a pouch cell battery, designed to protect a battery cell module and two bus structures of the pouch cell battery, wherein the battery cell module is positioned between the bus structures, each bus structure comprising a supporting seat and multiple busbars, each supporting seat being formed of an insulating and thermally conductive plastic material, and each busbar being a plate made of conductive material; each supporting seat being connected to the multiple busbars on the side opposite to the battery cell module, and each busbar being electrically connected to the battery cell module;the protective structure comprising a base, a top cover, and two terminal covers, wherein the base supports the battery cell module, while the top cover is connected to the base and positioned on the side opposite to the base, enclosing the battery cell module between the base and the top cover; each terminal cover connecting the base and the top cover at their respective ends and enclosing the battery cell module and the bus structures between the terminal covers; each terminal cover consisting of an outer shell and an insulating interface; the base, the top cover, and the outer shells being made of a flame-retardant, thermally conductive, and impact-resistant metal material;each outer shell having a central through-hole, each insulating interface being a shell-like structure made of an insulating and thermally conductive plastic material; each insulating interface being positioned adjacent to the supporting seat on the side connected to the busbars such that the insulating interface isolates the outer shell from the busbars; each insulating interface including a thermal conduction element protruding inwardly toward the adjacent bus structure and aligned with the through-hole, enabling the heat generated by the battery cell module to be transferredexternally through the thermal conduction elements and the through-holes to enhance the heat dissipation efficiency through the terminal covers; anda thermally conductive adhesive being applied between each terminal cover and the adjacent bus structure.Application No: GB2418157.0Examiner: Dr Andrew WilliamsClaims searched: 1Date of search: 17 June 2025Patents Act 1977: Search Report under Section 17Documents considered to be relevant:Category Relevant to claims Identity of document and passage or figure of particular relevance A - CN 218498211 U (SUNWODA ELECTRIC VEHICLE CELL CO LTD) Figure 1; description.
