Modeling and Analysis of a Hybrid PV/Second-Life Battery Topology Based Fast DC-Charging Systems for Electric Vehicles

Integration of vehicle charging infrastructures into the existing tram networks has gained a strong interest to tackle the lack of the charging infrastructures for Electric Vehicles (EVs) and Plug-in Hybrid Electric Vehicles (PHEVs). This article proposes a hybrid PV/Second-Life (SL) battery system that cannot only be used as a fast DC charging system for EVs or PHEVs, but also as an energy-storage system for tram network towards more green mobility. In this paper, the proposed hybrid PV/Second-Life (SL) battery system is designed and investigated in detail. The dynamic models of the PV and SL battery are developed and analyzed by using Matlab/Simulink. To efficiently integrate the proposed system into the tram network, advanced multiport interleaved power-converter (MIPC) and its control strategy are developed. Moreover, the simulation results are shown in this article to verify the dynamic performance of the proposed topology in different operating modes.
