Once the battery cells are joined together, they need to be reinforced with lateral braces, to protect the cell stacks from impact forces associated with a vehicle collision.
November 3, 2020
A major challenge identified in the EV battery assembly process was the critical requirement to join dissimilar cell stacks of different vehicles, as well as mixed material combinations, without generating heat or surplus waste material.
Common joining techniques such as drilling or spot welding are not suitable for battery module assembly because the heat generated and consequential metal fragments or welding splatter can harm and compromise the safety of the sensitive battery cells.
