energy storage systems (BESS)

You manufacture home storage, commercial storage or grid battery systems? We help you streamline your production of lithium-ion or sodium-ion batteries.

lithium-ion battery assembly with cell stacking process

tailor-made to your needs

customized battery assembly lines for energy storage systems

Our battery production equipment can automatically adapt to your product. The interaction by the employee via the HMI is no longer necessary. Depending on the requirements, the production system can process different battery types or sizes, both lithium-ion or sodium-ion based. 

Our core goals are 

  • higher quality
  • better process stability and a
  • lower scrap rate. 

We cover all processes in battery assembly such as: initial testing and identifying, cleaning, cell handling, stacking, compressing, framing, welding, gluing, filling, checking, screwing EOL testing, etc.
