Combination of double-layer capacitor and battery

By combining double-layer capacitors and batteries, the advantages of both technologies can be used to optimize the efficiency and service life of the energy storage system. A hybrid system increases reliability, as double-layer capacitors can support batteries with fast energy requirements. This is particularly effective for vehicles with regeneration brakes, as double-layer capacitors can quickly store the recovered energy, while batteries provide long-term energy requirements. If an application is mainly supplied by double-layer capacitors, a battery can support unplanned scenarios, such as recovering a vehicle in the event of a malfunction.
