Energy storage battery assembly process

Battery module made of cylindrical cells ● Battery modules made of pouch cells are designed so that the cells are stacked on top of each other and then interconnected. ● Due to their flexible envelope, the individual pouch cells can be placed in a frame beforehand. ● Gap filler for volume compensation or active and passive cooling elements can be inserted between the cells. ● The cell stack is braced in different ways and placed in the module housing. ● The volume expansion ("breathing") of the pouch cells during charge or discharge cycles must be taken into account in the module design.
