BENNING CMS Technology GmbH and PEM Motion GmbH have created MATLAB software that simulates their jointly developed ETA Leveling algorithm for battery management systems (BMS). According to the companies, this solution simplifies integration into industrial BMS without requiring additional hardware or extensive system modifications.
Slower aging process
ETA leveling is based on the observation that the efficiency and state of charge of individual battery cells change over time. These deviations lead to uneven aging of the cells, decreasing the overall capacity. The algorithm compensates for these differences, thereby slowing down the aging process. This can extend the service life of battery blocks. In second-life storage systems, the algorithm can help bring cells with different states back to a comparable level.
Module available for select collaborations
The MATLAB Simulink-based simulation model is used to test the algorithm before it is integrated into real systems. This allows users to test how the ETA leveling approach behaves under various operating conditions and evaluate its impact on battery life. The module is currently available to select collaborators for a limited time. According to both companies, the ETA leveling module can be directly integrated into existing development processes. It is intended for use in both new battery systems and aged or used battery blocks.
