Our FREQCON BESS second-life battery storage system is an energy storage solution that reuses batteries from previous applications, such as electric vehicles.

Even after years of use, batteries from electric vehicles often retain 70–80% of their original capacity. While this is typically no longer sufficient for automotive applications, it remains highly suitable for stationary energy storage systems. Instead of being directly recycled and leaving their remaining capacity unused, these batteries are given a “second life” in our energy storage system.

The applications are identical to those of our BESS MAX battery storage system.

Second-life systems are particularly attractive for sustainable applications and cost reduction. The increasing number of electric vehicles will lead to a growing availability of suitable replacement batteries in the long term. It is expected that costs will continue to decrease accordingly in the future. Furthermore, as electromobility advances, greater standardization of battery modules is anticipated, which will significantly simplify replacements. This will also have a positive impact on cost trends.
