• • • COVER STORY • • • * First: The connection platform is suitable for
all standard assembly processes (wire bonding, ribbon bonding, ultrasonic welding and laser welding) and it allows an assembly process that is up to four times faster than conventional welded connections with cables or ribbons. * Second – and this is what makes the new
InfiniCell generation special: Due to a patented process, the bus bar allows connection of plus and minus poles of the battery cells on the same side. This further simplifies the connection of the cells in the production shape and also offers advantages in the architecture. The bottom of the module remains completely free, so that the temperature management system can be installed there. That not only simplifies and accelerates the assembly process, but also reduces the space needed for the module. Electric vehicles require ever more storage
applications with increasing requirements for power density. Technologies are therefore needed that reduce space requirements without restricting efficiency. “InfiniCell is an ideal tool for this,” Mr Gueguen emphasised.
Safety at different levels “The issue of battery safety can be approached at several different levels,” Mr Gueguen said, “at the level of the single battery cell, the battery module or the battery pack.” That is a matter of the safety strategy and requires different safety tool modules. The modular concept is also retained with InBat Fuse and InfiniCell, which of course can also be used in combination.
“Mersen has long assumed the role of developing exactly the safety tools that are needed for the different safety architectures and strategies of its customers,” he added. Manufacturers and suppliers therefore work
together to set new developments in battery technology in motion, thus giving a powerful boost to continuing progress in the electric vehicle sector overall.
