WIPO Patent Application WO/2019/174086
Kind Code:
A1
Abstract:
The present utility model relates to an output electrical connection piece and a battery module comprising the output electrical connection piece. The output electrical connection piece comprises: a first welding portion, and a second welding portion connected to the first welding portion, wherein the second welding portion comprises a plate-shaped body and a boss disposed on the plate-shaped body; the plate-shaped body comprises a first surface and second surface that are arranged opposite to each other; and the boss is formed by the plate-shaped body protruding along a direction from the first surface to the second surface. The output electrical connection piece that comprises a boss and that is provided in an embodiment of the present utility model has strong high current capabilities, a simple structure and a low cost. In addition, the battery module adopts the output electrical connection piece, the output electrical connection piece may be pre-welded onto an output pole of an individual battery assembly, then the boss is extended out from an end plate of the battery module and is welded and connected to an output terminal. Compared to existing technology, the transfer connection process between the output pole and the output terminal is simplified, thereby reducing the complexity of the assembly process of the battery module.
