Assembly of battery systems and battery packs for electric vehicles

Final assembly lines for battery packs used in electric vehicles, buses and trucks

Strama-MPS offers turnkey assembly lines to finally assemble vehicle battery systems for electric and hybrid vehicle applications.

Many years of experience with battery modules

Whether BEV, REEV or PHEV, or passenger car, bus, municipal vehicle, lift truck, transporter or truck; the single battery modules provide the basis for complete high-voltage systems in all electric vehicles. Managing this process chain requires many years of experience in the sectors:

  • Automation
  • Connecting logistics workflows
  • Measuring and testing technology
  • High voltage technology.

Proven expertise

Strama-MPS has proven its expertise by globally established applications for well-known customers. We will also gladly offer processing of your battery modules to high quality, 100% tested and ready-to-install battery systems. High throughput rates, flexible assembly strategies, sophisticated test processes and monitored assembly steps are typical for our solutions.

Flexible integration of manual and automatic processes

By means of specifically developed provisioning systems the processed modules are manually or automatically taken from the delivery packaging and fed into the stations. Identification and sorting, but also the defined module positioning and fixing occurs on the assembly lines developed by Strama-MPS. These lines are able to assemble further parts automatically, such as cooling systems, connector plugs and cable harnesses as well as many other components, or we create worker stations for you which result in highly variable production possibilities by being flexibly linked to the automatic processes in the line.

Continuous quality inspection by advanced testing systems

As an expert in the field of testing systems and test equipment Strama-MPS integrates all necessary test steps giving them a full overview of the produced quality. For instance, End-of-Line-Testers (EoL) covering the following test criteria are integrated:

  • Cooler tightness
  • Housing tightness
  • SW checking and flashing, if necessary
  • Voltage test
  • Temperature test
  • HV test· Insulation test
  • Charge status, with recharging, if necessary

Individual assembly concept for your application

We will gladly prepare an assembly concept for your product with customized logistics solution. Whether robot, AGV, belt system or trolley: We provide the right solution for you.

Advanced simulation tools for maximum project safety

If required, we have advanced simulation tools available to check the production strategies already at the early stages of implementation. Thus, we give you best opportunity to plan ahead and reliable data on worker deployment, degree of self-containment and throughput rates.

Automatic data acquisition, evaluation and visualization

Production data are recorded, evaluations and statistics issued and the processes visualized by the process software connected to the host PC.

24/7 Service worldwide

Our service is staffed around the clock. 24 hours, 7 days a week. No matter from where you call, we are always at your service. Our worldwide agencies guarantee short response times and local contacts.
