The study is focused on the air supply management with the objective to optimize the inlet air pressure and stoichiometry given by the compression system. A simple optimization method is given to maximize the voltage gain including the voltage drop due to the compression process. The optimization has to take into account the outlet relative air humidity (optimization constraint) leaving the fuel cell to avoid drying or flooding problems. The optimization results show that working at fully humidified air at the inlet is not always a good solution especially for low air mass flow rates because of the high level of air stoichiometry to avoid flooding of the polymer membrane. On the other hand, it is better to work at fully humidified air at the inlet at high air mass flow rates. In all the cases, the optimal pressure is less than 2.5 bar which gives an indication for the design of air compressor for fuel cells.","PeriodicalId":430886,"journal":{"name":"2005 IEEE Vehicle Power and Propulsion Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123087104","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 discusses the design, prototype realisation and test validation of a switched reluctance (SR) machine for a mild-hybrid power assist, starter/alternator application that has performance requirements of both high starting torque and a wide speed range at full power. Whilst a number of papers have published on SR machine design for automotive starter/alternator applications, a comprehensive case study discussing the design and application issues has not been published. The paper focuses on the impact of performance requirements and volumetric and environmental constraints on the machine design. It is shown that a higher number of stator and rotor poles are more appropriate for utilisation of the available active volume. Whilst various operation and fault scenarios have been presented for SR drive-systems, the paper also discusses test observations that suggest the potential for transient self-excitation of the SR generator via residual magnetisation of the machine rotor, a fault scenario that has only been briefly reported upon.","PeriodicalId":430886,"journal":{"name":"2005 IEEE Vehicle Power and Propulsion Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123582090","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}

Long-term laboratory tests have been conducted to characterize these cells. The results address state-of-charge measurement and characterization, input-output charge efficiency, and needs and results with charge equalization. The results show that open-circuit voltage can provide a basis for state-of-charge measurement. High input-output energy storage efficiency is a key benefit of Li-ion technology-a vital performance parameter for hybrid vehicles. Charge equalization is an important consideration for Li-ion applications, and active equalization is needed to insure safe operation and deliver long life. Present commercial devices vary significantly among manufacturers.","PeriodicalId":430886,"journal":{"name":"2005 IEEE Vehicle Power and Propulsion Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123735030","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}

In the structure of the electric power system of modern EVs/HVs, more than one of these units may be employed to improve the performance and efficiency; hence utilization of a multi-input DC-DC converter is inevitable to obtain a regulated bus DC voltage. In this paper, a review of multiple input DC-DC power electronic converters (MI-PEC) devoted to combine the power flow from several on-board energy sources of an EV/HV is presented. Several multi-input DC-DC converters based on various topologies are studied and analyzed.

Such changing trends have increased the use of switch mode DC-DC converter that would require very low conversion/duty ratios. Duty ratios close to zero greatly deteriorate O/P voltage/current and hence affect control signals. The use of cascaded DC-DC converters increases this conversion ratio. Different modeling techniques based on averaged, sampled-data and detailed model are discussed. Based on these modeling approaches, cascaded system behavior and dynamics are observed and the importance of hierarchical modeling is emphasized.","PeriodicalId":430886,"journal":{"name":"2005 IEEE Vehicle Power and Propulsion Conference","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122035199","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 water pump was driven by a controlled electric motor. A battery was used as power source for the electric motor. In the proposed application the thermal behaviour of all components in the cooling circuit (engine, pipes and cooler) is modelled.

For example, the number of power converter varies from a few converters in a conventional car to hundreds in a international space station. A multi-converter power system is composed by the presence of different solid-state power converters integrated together in order to form an interconnected system, generally very complex. In this work stability conditions are investigated, starting at first from a conventional mathematical model derived using state-space averaging method. Preliminary experimental tests, however, proved the importance of parasitic parameters on the stability of the whole system. A more complete model that takes into account real parameters is then introduced, in order to obtain more precise predictions on critical load values. Final experimental test verified the validity of the model and the accordance with predictions.","PeriodicalId":430886,"journal":{"name":"2005 IEEE Vehicle Power and Propulsion Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116272602","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}

High torque pulsation is the major disadvantage of most IPM motor configurations. Choosing proper number of stator slots as well as winding distribution and increasing number of phases are among the possible solutions for reducing torque pulsation. In this paper, five-phase interior permanent magnet motor with fractional-slot stator is studied. It is shown that despite other IPM motors; the proposed five-phase IPM motor with fractional slot has a very low torque pulsation. The mathematical model of five phase interior permanent magnet motor is given. Also it is shown that the MMF of the five-phase motor can remain unchanged by applying proper control algorithm in case of loss of up to two phases. A prototype four pole, IPM motor with 15 stator slots has been built and is used for experimental verification.","PeriodicalId":430886,"journal":{"name":"2005 IEEE Vehicle Power and Propulsion Conference","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132813598","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}
