Hybrid energy storage system of batteries and double layer capacitors (EDLC) System analysis, circuit topologies and practical implementation in a digitally controlled system for the low-voltage range.
One of the sticking points in Electro mobility as well as in Renewable Energies is the energy storage. Lithium-ion batteries are at that time the most interesting option among the storage technologies. Battery powered tools or other highly reliable battery powered systems are typical applications where the life span and the robustness play a significant role.
But with progressive technological development double layer capacitors (EDLC, depending on manufacturer also ultra-capacitors, super-capacitors also named green cap) are more and more often advisable for battery replacement.
