Problems solved by technology

[0002] In the prior art, the cover plates of the battery are all one-piece cover plates. When the one-piece cover plate is connected to other structures, welding is mostly used, so that there are many welding positions on the cover plate. When welding inside one side of the cover plate , the heat generated by welding will also generate thermal shock on the other side of the cover, causing damage to plastic parts such as seals, thereby reducing the reliability of the connection between the cover and the shell

Abstract

The invention relates to the technical field of batteries, and discloses a high-capacity battery which comprises a cover plate and a shell, a containing cavity with one open end is defined in the shell, the cover plate is arranged at the open end of the shell, at least one battery cell is arranged in the containing cavity, the cover plate comprises at least two cover plate bodies, and each cover plate body is suitable for being fixedly connected with the shell, every two adjacent cover plate bodies are connected in a welded mode, each cover plate body is provided with a pole capable of being electrically connected with a pole lug of at least one battery cell, and the at least two cover plate bodies comprise at least one positive electrode cover plate and at least one negative electrode cover plate. The cover plate of the high-capacity battery disclosed by the invention comprises at least two cover plate bodies, and heat generated when one cover plate body is welded with other structures does not impact the other cover plate bodies, so that damage to plastic parts such as sealing parts is reduced, and the reliability of connection between the cover plate and the shell is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a large-capacity battery. Background technique [0002] In the prior art, the cover plates of the battery are all one-piece cover plates. When the one-piece cover plate is connected to other structures, welding is mostly used, so that there are many welding positions on the cover plate. When welding inside one side of the cover plate , The heat generated by welding will also generate thermal shock on the other side of the cover plate, causing damage to plastic parts such as seals, thereby reducing the reliability of the connection between the cover plate and the housing. Contents of the invention [0003] Based on the above, the purpose of the present invention is to provide a large-capacity battery, which reduces damage to plastic parts such as seals during welding inside the cover plate, and improves the reliability of the connection between the cover plate and the casing. ...
