Battery Management System

Intelligent control for maximum battery performance

The BMS is the “brain” of every battery unit and monitors all relevant parameters such as voltage, current, and temperature. It ensures optimal use of the battery and protects it from overload, overheating, and deep discharge.

Through precise cell balancing and state-of-charge calculation, the BMS ensures a long service life and maximum safety. It detects errors at an early stage and controls charging and discharging processes efficiently. Indispensable for applications ranging from home storage to high-performance energy systems.

For demanding energy storage solutions, the BMS also offers interfaces for communication and integration into higher-level systems. This ensures reliable control and safe interaction of all components. The basis for a sustainable energy supply.
