Extension systems for batteries

Battery extension systems for charging or discharging up to 4 batteries together.

The project consisted of the development and production of various extension systems integrated in robust housings.

These extension systems can be used to charge or discharge up to 4 batteries together. Charging and discharging current up to 30A is possible. Total charging and discharging current is up to 120A. The housing has an IP66 protection class.

The special challenge was to develop different extension systems that meet the high demands of the customer (up to 4 batteries in parallel or a switch box for charging and discharging) and are also provided with the necessary safety features.

Thanks to our well thought-out adapter system, we are able to provide the right connector for every battery pack.
 

If you wish, we can also configure a connection box for your application - Feel free to contact us!

Research focus


Our goal was to develop mobile extension systems that are optimally adapted to the needs of the industry. 
It was important for us to design the extension systems in such a way that they remain compact and mobile despite high load capacities.

During development, we paid special attention to the universal range of application and the diversity that is possible with the different connections and number of connections. 

Our solution


We have developed four different battery extension systems for this project, consisting of a switch box for four batteries, a 4-fold parallel connection box as well as a 3-fold and 2-fold parallel connection box.

Areas of application
