Energy storage system network topology

What is a D-Hest energy storage topology?

We suggest the topology class of discrete hybrid energy storage topologies ( D-HESTs ). Battery electric vehicles ( BEVs) are the most interesting option available for reducing CO 2 emissions for individual mobility. To achieve better acceptance, BEVs require a high cruising range and good acceleration and recuperation.

What are the four topologies of energy storage systems?

The energy storage system comprises several of these ESMs, which can be arranged in the four topologies: pD-HEST, sD-HEST, spD-HEST, and psD-HEST. Detailed investigations will be undertaken in future work to examine special aspects of the proposed topology class.

Are reconfigurable energy storage topologies possible without DC/DC converters?

Besides, reconfigurable topologies on cell level and module level, without the need of additional DC/DC converters, have been investigated in the literature and are also presented and reviewed. We then suggest a new topology class of discrete hybrid energy storage topologies, which combine both research topics.

What are the basic interconnection topologies of energy storage elements?

Basic interconnection topologies of energy storage elements having the same cell type and chemistry. (a) Serial interconnection, (b) parallel interconnection, and (c) parallel–serial interconnection to increase storable energy, capacity, or ampacity and/or achieve a higher output voltage.

What are the different types of hybrid energy storage topologies?

The topologies examined in the scientific literature to date can be divided into the passive hybrid energy storage topology ( P-HEST ), which is presented in Section 2, and the active hybrid energy storage topology ( A-HEST ), which is presented in Section 3.

What is the PSD-Hest topology?

The last sub-topology is an extension of the spD-HEST. First, the ESMs are connected in parallel via crossbars and are serially connected to each other ( Fig. 8 e). We therefore call this topology the psD-HEST. Again, the capacity, voltage level, ampacity, and characteristics of the energy storage system can be scaled almost arbitrarily.
