Problems solved by technology
The disadvantage of this method is that, during the manufacturing and assembly process of the battery module or during the user's use, when a problem is found with a certain part of the module, the module cannot be disassembled for repair, replacement or maintenance measures, and finally The whole battery module is often scrapped by giving up
[0003] In addition, since the positive and negative terminals of the battery are made of aluminum-copper dissimilar metals, when the individual batteries are electrically connected through aluminum sheets, electrochemical corrosion is likely to occur between the aluminum-copper dissimilar metals, which affects the reliability and life of the product

The invention discloses an electrical connection device of a battery. The electrical connection device comprises adaptor members and a connection member, wherein the adaptor members are fixed on the battery and are electrically connected with battery terminals, the connection member is detachably connected with one or more than two adaptor members fixed on the battery, and detachable connection is also electrical connection. Compared with the prior art, the electrical connection device of the battery has the advantages that by the detachable design of the electrical connection device, the service lifetime of a battery module is remarkably prolonged, the reliability of the battery module is remarkably improved, and the production and assembly efficiency of the battery module is improved. Moreover, the invention also discloses the battery module, an electrical connection method of the battery and a battery module assembly method.
Description
technical field [0001] The invention belongs to the field of batteries, and more specifically, the invention relates to a battery module and a battery electrical connection device and an electrical connection method thereof. Background technique [0002] In the battery module in the prior art, the batteries are electrically connected through the connection piece, and the connection method between the connection piece and the battery terminal is welding connection. The disadvantage of this method is that, during the manufacturing and assembly process of the battery module or during the user's use, when a problem is found with a certain part of the module, the module cannot be disassembled for repair, replacement or maintenance measures, and finally The whole battery module is often scrapped by giving up. [0003] In addition, since the positive and negative terminals of the battery use aluminum-copper dissimilar metals, when the individual batteries are electrically connecte...
