➀ Fraunhofer IEE, in collaboration with Skeleton Technologies and AVL, has developed simulation tools for hybrid storage systems that can extend battery life by up to 20%. ➁ The core of these tools is a degradation model based on the BaSiS simulation environment, which predicts battery aging under realistic conditions. ➂ These tools allow for optimized configurations and control algorithms to find the best combination of supercapacitors and batteries for specific system designs and operational scenarios.
