Customised power electronic solutions for a wide range of battery storage applications

Demonstrator 480s 0 – 1500 V DC

Your Advantages

20 %

Up to 20 % lower costs

50 %

Up to 50 % longer lifetime

90 %

Losses reduced by up to 90 %

The integration of previously separate components into one platform has the dual benefit of reducing costs by up to 20 % while also increasing the efficiency and reliability of the overall system.

The use of intelligent charging and discharging processes, which are individually tailored to each cell in the system, prolongs the service life compared to existing solutions.

The use of compact and efficient power electronics at the cell level has the potential to reduce energy losses by up to 90 %.

  • Individual support:
    With the integration of our solution

Principle of operation





  • Default (off) state
  • All battery terminals
  • Maximized safety:
    system output is 0 V
  • Stage does not contribute
    to system output voltage
  • Longer lifetime: weak cells
    are loaded less, defective
    cells are bypassed
  • System not limited by weak
    or defective cells
  • Stage switched for positive
    output voltage
  • Stage switched for negative
    output voltage

For a complete system, many battery cell
stages are connected in series.
Our power electronics platform controls all
stages to deliver the desired system output.
