Abstract
The combination of batteries and ultracapacitors improves the peak current characteristics of the electrical energy storage system, minimizes battery degradation significantly, and ensures greater flexibility thanks to digital control. In a wide variety of applications, this technology additionally contributes to extremely high levels of reliability while enhancing the capacity of development effort.
In cooperation with an industrial research partner, engineers from the Faculty of Electrical Engineering at the University of Applied Sciences Zwickau have invented a novel kind of Hybrid Energy Storage System (HESS). By combining a battery and a double-layer capacitor stack (ultracaps), an electric energy storage system has emerged that improves peak current characteristics, extends the battery lifetime considerably, and ensures greater flexibility thanks to digital power control. It therefore improves reliability in the most diverse applications, especially, for high-load power tool drives, E-Bikes, electric vehicle applications or professional drones.
