   Electric and Hybrid Vehicles Battery Charger Cluster Locations in Urban Areas
By Vladimir KATIC [View]
[Download]

Abstract: The cluster of EVs' battery chargers is expected to become reality in many European cities in the near future. The strategy for positioning these chargers on the streets, especially in the urban city centres should include numerous parameters, where some of them may not be technical. The paper presents a proposal of procedure for placing the set of battery charger clusters in a city centre. Two examples are presented in a case where there are restrictions on building the new electricity infrastructure and expectation that charging time is short. The main concern is placed on power quality issues, as current harmonic distortion may be very high. It is shown that clusters with 2 to 6 chargers are found to be the most suitable. It is also noticed that current distortion is getting lower as number of chargers is increasing.

   Investigation on Power Electronics Topologies for Inductive Power Transfer (IPT) Systems in High Power Low Voltage Applications

Abstract: In this contribution the optimal power electronics topology in SS-compensated IPT systems for Electric Vehicles (EVs) is investigated in terms of required rated semiconductor power and efficiency. The novelty of this paper is the focus on high power (sup. 1 kW) and low output voltage (inf. 100 V) applications. It is shown that the required semiconductor power which can be assumed to be proportional to the chipsize and thus the costs of a semiconductor device is roughly 10\% lower for the topology with primary DC/DC conversion than with secondary DC/DC conversion. Furthermore it is found that the topology with primary DC/DC conversion shows the highest overall efficiency, while the topology with secondary DC/DC conversion results in a better worst case efficiency. A general rule can be derived that the winding ratio for both topologies should be chosen as high as possible.

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

Abstract: Integration of vehicle charging infrastructures into the existing tram networks has gained a stronginterest to tackle the lack of the charging infrastructures for Electric Vehicles (EVs) and Plug-in HybridElectric Vehicles (PHEVs). This article proposes a hybrid PV/Second-Life (SL) battery system that cannotonly 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.
