Electric connecting sheet and battery module using same

Abstract

The invention relates to the technical field of electric connecting pieces, and particularly provides an electric connecting piece and a battery module using the same. The battery module comprises a battery cell and electric connecting sheets connected between different poles, the electric connecting sheets are formed by overlapping more than two sheet bodies, at least one sheet body has the following characteristics: at least one side surface of each sheet body is provided with a concave-convex structure for increasing the heat dissipation area of the side surface, and the side surface is adjacent to other sheet bodies. The extending direction of a channel formed by each concave-convex structure is parallel to the adjacent side surfaces between the sheet bodies and is perpendicular to thethickness direction of the electric connecting sheets, and in the direction, a structure influencing gas flow does not exist, so that the concave-convex structures can form a complete channel for gasflow, the heat dissipation effect of the electric connecting sheets is improved, the temperature rise of the electric connecting sheets is effectively controlled, and the battery module is more stable during working.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an electrical connector and a battery module using the electrical connector. Background technique [0002] In the field of power cells, in order to obtain a larger output current and output voltage, multiple cells are often assembled into one body to form a battery module. The cells in the battery module are connected in series or in parallel and then discharged together. In the above structure, electrical connecting sheets are often used to realize the conductive connection between adjacent cells and between the battery module and the connecting wire harness. [0003] At present, in the battery module, the electrical connecting piece connected between the two batteries includes connecting parts located at both ends of the strip-shaped main body of the electrical connecting piece, and the connecting parts are connected to the battery cells by welding, such as the pa...
