Learn MoreMechanical fastening is another method of joining electrical components in the BEV's powertrain, but in the context of battery pack assembly, it is mainly used for the assembly of modules. The following paragraphs provide some brief but informative descriptions of each of the four most commonly used welding methods for battery module assembly.
applicability of joining methods is discussed with hierarchical levels of battery manufacturing. material, metallurgical, and mechanical challenges. technologies is quantified. Recommendations for further investigation of joining technologies are made based on Pugh matrix scores, MRLs, and application potential.
Other joining methods such as micro-tungsten-inert-gas welding (micro-TIG), micro-clinching, soldering, and magnetic-pulse welding exist and have been proposed for battery assembly applications, but they are not well established, and therefore their feasibility is still being evaluated, or they are not widely used in the industry.
Welding processes applied in the battery manufacturing process include ultrasonic welding and laser welding, among others. The laser welding process offers control over heat input between dissimilar materials, allowing for high-speed welding and automation, making it well-suited for mass production .
This paper reviews the applicability of major and emerging joining techniques to support the wide range of joining requirements that exist during battery pack manufacturing. It identifies the advantages, disadvantages, limitations, and concerns of the joining technologies.
Process optimisation is by far the most researched area of quality assurance for battery welding applications. Most of the studies have been carried out either as pure experimental investigations to find the process parameters that optimise one or more KPIs of a joint, suppress defects, or validate a process model.
