Abstract

The invention provides a battery module and a welding system and relates to the technical field of battery modules. The battery module comprises a plurality of battery cells, a battery cover, a first current collector plate and a second current collector plate, wherein the battery cover and the first current collector plate are matched with the battery cells; the battery cover is arranged at two ends of the battery cells in a sleeving manner; the first current collector plate is contacted with a conductive part of the battery cover so as to converge current of the battery cells; the second current collector plate is welded on the first current collector plate to form a wiring terminal of the battery module used for outputting electric energy. Due to the battery cover and the first current collector plate, the battery cells are conveniently connected in parallel or series so as to form a battery pack. A hollow gap is formed in the second current collector plate, so that welding current can be centralized, the welding time is further shortened, and the welding efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of battery modules, in particular to a battery module and a welding system. Background technique [0002] With the rapid development of the advantages of the new energy industry, the new energy industry will become an important breakthrough for countries all over the world to cultivate new economic growth points. In the field of new energy battery module industry, the welding of battery modules is mainly divided into: ultrasonic welding, laser welding and resistance welding. At present, there are many deficiencies in the existing battery modules. For example, when welding the voltage acquisition line (also known as the second current collector or current collector plate) in the battery module, the existing battery module takes a long time to heat up, and the The formation of nuclei requires filler metals such as welding wire or electrodes, and oxygen, acetylene, hydrogen, etc. are also required as w...
