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

Demonstrator 480s 0 – 1500 V DC

Your Advantages

0 %

Up to 20 % lower costs

0 %

Up to 50 % longer lifetime

0 %

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 %.

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
