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

Demonstartor 480s 0 – 1500 V AC/DC

Our Advantages

20%

Up to 20% lower cost

50%

Up to 50% longer lifetime

90%

Losses reduced by up to 90%

The integration of previously separate components into this 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, doubles 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 loss by up to 90%.

Positive

Negative

  • Default (off) state
  • All battery terminals
    disconnected
  • 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.
