Abstract
The invention discloses a battery pack welding process which comprises the following steps: forming a battery pack according to a design process and a connection requirement of a product, and fixing the battery pack; determining welding process parameters according to the determined welding type and the structural characteristics of the battery pack; selecting and assembling a connecting aluminumbusbar; according to the selection specification of the battery cell and the connection mode of the aluminum busbar, hollowing the contact part welded to the battery cell and the aluminum busbar, andreserving a preset welding range; reserving a welding area and a welding width; and debugging a welding machine according to preset welding requirements, and performing point-to-point welding by combining a welding fixture. According to the scheme, the welding process of the product is optimized; the overall power of the welding machine is reduced, the thickness of a welding point of a large and medium power battery pack connecting piece is reduced, the welding firmness and reliability of a large and medium power battery pack product are ensured, the current bearing capacity is ensured, the cost is reduced, and the process difficulty and waste caused by quality redundancy in the production process of small and medium-sized enterprises are solved.
Description
technical field [0001] The invention relates to the technical field of battery pack welding, in particular to a battery pack welding process. Background technique [0002] At present, due to the large volume and power of the high-current battery pack, the welding process is not perfect, resulting in the thickness of the welding point of the battery pack connection piece being too large, which cannot guarantee the ability of the battery pack to carry current, nor can it guarantee the firmness and reliability of the welding, which affects the product. quality, resulting in product redundancy and waste. Contents of the invention [0003] The main purpose of the present invention is to propose a battery pack welding process, aiming at optimizing the welding process of products, solving the welding problem of high-current battery packs, and realizing high-current discharge of power batteries. [0004] To achieve the above object, the present invention provides a battery pack w...
