Battery Module: Manufacturing, Assembly and Test Process Flow. In the Previous article, we saw the first three parts of the Battery Pack Manufacturing process: Electrode Manufacturing, Cell Assembly, Cell Finishing. Article Link In this article, we will look at the Module Production part.
Correct cell assembly is crucial for safety, quality, and reliability of the battery, and an essential step in achieving complete efficiency of the battery. Here is a more detailed look at the battery cell assembly process: Cathodes: Lithium cobalt oxide, lithium manganese oxide, lithium nickel cobalt aluminum oxide, or lithium iron phosphate.
Fully automated battery assembly lines require machine vision technology to guarantee a collision-free assembly process. The ISRA VISION PowerPICK3D ensures a consistently high and reliable inspection quality based on 3D images that recognize very small parts, irrespective of their geometry or material.
The battery tray assembly consists of several production steps. Depending on the battery design and manufacturing processes, manual tightening with bolt positioning and process control, or flow drill fastening with K-Flow technology can bring the needed process quality, productivity and flexibility.
After the battery module is assembled, it needs to be placed into the battery tray. As this tray is a key structural component of the vehicle as well as integral in protecting the battery cells, it needs to be of the highest strength and stability.
The typical cell types on the market are currently cylindrical cells, prismatic cells, and pouch cells. Many manufacturers use prismatic cells since they can be stacked eficiently. We have outlined a complete battery assembly process for prismatic cells – from the single cell to the finished battery pack.
