6 FAQs about [Digital energy storage system topology reconstruction]

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.

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 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.

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.

What is a reconfigurable energy storage system?

The framework was developed for the reconfigurable energy storage system suggested by Kim and Shin which consists of energy storage cells each surrounded by six on/off switches so that the interconnection of these storage cells could be reconfigured in series, parallel, or combinations ( Fig. 7 e) .

Can network structure optimization improve energy storage capacity?
