Herein, the term battery assembly refers to cell, module and pack that are sequentially assembled for EV fields. The individual electrochemical cell can be applied in portable electronics such as cellphones, cameras and laptops [4, 5].
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.
Although there are only two companies from Korea to enter the top 10 assignees, they have a total global share of 66.9, 76.3 and 80.9% for cell, module and pack, respectively, indicating that Korean companies have the leading R&D for battery assembly.
Aside from Korean companies, Japanese companies also account for a significant portion of battery assembly, such as Toyota, Hitachi, Panasonic, Nissan, Sanyo, Sony, Daikin and Toshiba. Among them, Toyota and Hitachi are representative companies, and they both enter into the top 10 assignees in the design of battery assembly.
Expect new battery chemistries for electric vehicles and a manufacturing boost thanks to government funding this year. BMW plans to invest $1.7 billion in their new factory in South Carolina to produce EVs and their batteries. AP Photo/Sean Rayford Every year the world runs more and more on batteries.
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.
