The proposed strategy consists in regulate the EV battery charging current in function of the total home current, aiming to prevent overcurrent trips in the main switch breaker. Computational and experimental results were obtained under real-time conditions to validate the proposed strategy. For such purpose was adapted a bidirectional EV battery charger prototype to operate in accordance with the aforementioned strategy. The proposed strategy was validated through experimental results obtained both in steady and transient states. The results show the correct operation of the EV battery charger even under heavy load variations.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117230397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper presents a brief description of the proposed IPT system and magnetic core structure, the strategy for the converter operation and the design of the isolating transformer. It also analyses the impact of misalignments of the IPT system on the on-board charger behaviour and control in terms of charging capability.

With considering several hypothesis (linear magnetic modelling, only first and third harmonic terms in the back-emf and current spectrums), an optimization problem that aims to maximize the torque for given maximum voltage and RMS current is formulated: the optimal torque sharing among the two virtual machines (the two dq-axis subspaces) that represent the real five-phase machine is thus calculated for any mechanical speed. For an inverter and a DC voltage sized with only considering the first harmonic of back-emf and current, the problem is solved with changing the ratio between the two virtual machine back-emfs and changing the ratio between the two virtual machine inductances. The results are examined by introducing particular speed points.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123029007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of the infrastructure facilities date from the middle of last century and were not designed for today's energy concerns or energy-efficiency as is the case of \"Montarroio\" substation that still uses mercury arc rectifiers. Energy-efficiency substation's improvement is a key issue to maximize energy-savings. This paper describes the main studies and proposals made to achieve energy saving and cost reductions. One week long measurements at the two still active substations and the analysis of one year electricity bills were made. It was concluded that investments in new rectifiers are needed and that some of the studied options have a payback of just a few years. Implementing it can provide the rehabilitation of this means of transportation, assuming it as a real alternative to the currently mainstream systems, based on diesel bus.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133753381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is clearly the case, if the pedal input integrates the driver's brake demands. The challenge is to deal with vehicle safety and recovery efficiency. Thus, this work focuses on the implementation of a cooperative braking strategy, involving brake pressure control and regenerative brake control. The objectives are to trade, until limits, the rear wheel friction brake by regenerative brake and to improve the brake performance. To achieve this, this paper proposes a cooperative brake force distribution strategy. For design purpose, a simulator based on empirical results has been developed and the feasibility of the strategy is evaluated through experimentation.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115263197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrical drives with five-phase induction motors are considered for application in electric vehicles. Space vector modulation (SVM) is the most common options for controlling a five-phase inverter. However, if the battery level cannot ensure the controllability over a wide speed range of EV drive, the supply voltage has to be elevated. Bidirectional impedance source inverters (e.g. Z- source inverter, qZ-source inverter) have been presented suitable for EVs. The concept of Z-source inverters has been recently extended to transformer-based inverters (e.g. Trans-Z-source inverter, T - source inverter) which use coupled inductors with an appropriate turns ratio. Unfortunately, coupled inductors store significant portion of the energy during boost operation which tends their cores to saturate at higher currents. The use of four element LCCAt-source (inductor-capacitor-capacitor- autotransformer) network allows proposed switched- autotransformer inverter for obtaining high voltage gain while ensuring high modulation index and reduced volume of inductive elements. Simulation and experimental results using the laboratory model of switched-autotransformer inverter with designed 4.3 kW, 30V five-phase induction motor are shown to verify the effectiveness of the proposed system.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125275940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
