A multi-point acquisition battery cover structure
By designing a multi-point acquisition battery cover structure, and using a cylindrical flange and trapezoidal groove combined with guide plates and structural adhesive, the problem of signal transmission from the embedded temperature sensor in the lithium-ion battery disrupting the seal was solved. This achieved high sealing performance and effective signal transmission for the lithium-ion battery, and improved the battery's thermal runaway early warning capability.

Abstract
This invention relates to a multi-point acquisition battery cover structure, comprising a battery cover, terminals, and enameled wires. The battery cover has two cylindrical flange structures, each with a cylindrical through-hole. Symmetrical structures are designed at both ends of the cylindrical through-holes. Each symmetrical structure includes trapezoidal grooves at both ends of the cylindrical through-holes, a circular groove along the waistline of the trapezoidal groove, and a groove at the outermost edge of the trapezoidal groove for installing guide plates. The symmetrical structure enhances the battery cover's ability to withstand pressure differences between internal and external surfaces. The guide plates have multiple circular holes, with each enameled wire passing through one of these holes. The battery cover flange structure is sealed by injecting structural adhesive into the inner cavity of the flange structure.
