In order to achieve a good separation between the coils, magnetic resonance coupling instead of conventional inductive coupling is used in these systems. The frequency characteristics of the wireless power transfer efficiency for different offsets between the transmitting and receiving coils of such a resonance-based wireless charging system were investigated both theoretically and experimentally. It was seen that if a fixed frequency is used, the resonance coupling system is very sensitive to imperfect positioning of the vehicle, leading to significant deterioration in efficiency. But by allowing for the transmit frequency to adapt to the position of the coils, the maximum efficiency can be maintained even for relatively large deviations of more than 20cm. Hence, in this work, a frequency agile resonance-based wireless charging system is proposed. The design senses the current in the transmitting coil and adapts the frequency such that maximum efficiency is maintained. The proposed system will provide significantly better power transfer efficiency than conventional fixed frequency designs when applied to EV charging under practical real-world scenarios.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129147023","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}

One of the electric powertrain of fuel cell electric vehicle consists of fuel cell, rechargeable energy storage device, boost chopper and bidirectional chopper. The smaller size of the power converter on fuel cell hybrid electric vehicle is expected. Thus, interleaved configuration has advantage in converter size. This paper shows driving characteristics of an interleaved boost chopper connected to fuel cell and of a bidirectional chopper connected to electric double layer capacitor (EDLC). It is required that the bidirectional chopper is controlled by control method which considers state of charge (SOC) on EDLC. This paper proposes a control method which considers SOC on EDLC, and shows driving characteristics of the choppers for FCHEV in three states. As results of experiment, it is verified that two DC-DC converter converters can be operated adequately. In order to verify the power flow in three states in FCHEV, it is necessary to limit current value or duty ratio and to propose control method which considers SOC on EDLC.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127555570","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}

Americans driving habits are based on a century of experience with gas tanks. This experience of run-until-empty followed by a fill-up-to-full at a public gas station is not how EV's will be used. This legacy places too much emphasis on public high-speed Level-2 (L2) charging. All EV's are designed to be charged overnight from standard 115v outlets, Level-1 (L1), which can give about 32 miles of range for 8 hours charge[1]. The overnight charge plus another 8 hour charge from 115v at work, gives the EV driver a daily range of at least 64 miles. This is well above the national average commute (32 miles round trip) and actually satisfies more than 90% of USA commute distances. In addition, mid-range L1 charging to not-fully-full and daily use to not-fully-empty is the best long-life profile for EV batteries. The EV is not intended to out-right replace all gasoline vehicle usage, but is ideal for the commuter who can plug-in at home and plug-in at work. An EV is more like a laptop or cell phone that expects to be plugged in at home and at work when not in use. The commuter vehicle spends at least 16 hours a day just sitting at home and at work, where low-speed L1 charging can exceed 90% of all USA commuter distances. The paper concludes with a list of recommendations for the EV infrastructure rollout.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131377796","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}

A power architecture is proposed for megawatt multifunctional EV charging stations to get over the disadvantages of the existing technologies. The power architecture is integrated with grid energy storage, renewable energy sources and it can carry bidirectional power flows. The proposed power architecture cannot only charge EVs but also simultaneously achieve grid support functions. The proposed power architecture can also achieve high efficiency and high reliability. Bidirectional DC/DC converters, medium frequency transformer design and control scheme are also briefly discussed in the paper. Finally, simulations are conducted to verify the proposed technical approach.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133866875","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}
