Assembly lines for battery modules and battery packs
The range of electric vehicles is determined to a great extent by the performance of the energy storage systems used. Our assembly and testing systems broaden the horizon.
Strama-MPS supplies turnkey assembly lines for pre-assembly of battery modules and final assembly of battery systems for electric and hybrid vehicles. High throughput rates, flexible assembly strategies, sophisticated testing processes and monitored assembly steps characterize our solutions. We combine years of experience in the fields of automation, logistical linking, measurement and testing technology and high-voltage technology.
BATTERY MODULE ASSEMBLY LINES
In our battery module assembly lines, high-quality prismatic, cylindrical, and pouch cells are processed using state-of-the-art equipment. The modules are stacked and electrically connected at high speed. The product portfolio in this area includes: wire bonding, laser bonding, resistance welding, and laser welding. The length and width of the stacks are largely configurable. All modules undergo a 100% functional test before being passed on to subsequent processes. Industry 4.0 and end-to-end traceability are standard features in all our facilities.
The processing of battery cells requires specific process knowhow and a lot of experience. That is exactly what makes us a leader in engineering. We are thus achieving that finally the full power can be utilized in electric vehicles – at any time and permanently. Even critical issues, such as swelling, overheating, short circuits and salification can be consistently solved with our assembly systems.

BATTERY PACK ASSEMBLY LINES
In our assembly lines for battery packs the modules are fed into the stations either manually or via specifically developed supply systems. Identification, sorting, positioning, fixing and connecting of the modules carried out fully automatically. Other components, such as cooling systems, ventilation bodies, connectors, wiring harnesses, etc. can be mounted manually or automatically. This involves an inspection step after each assembly station to ensure a zero defect production.
Today’s battery systems are essential, complex and multi-functional modules in electric vehicles. With our assembly lines, the vehicle manufacturers and component suppliers may quickly and easily implement their development ideas. Also for the production of battery trays, we deliver efficient solutions that combine precision with effectiveness and fulfill the highest standards in terms of cleanliness, leak tightness and safety.
