However, such a risk only exists in some worst cases, and at most times unnecessary. Active gate drive is an emerging technology to solve this trade-off between efficiency and reliability. This paper propose an optimal gate drive current according to the operating condition to minimize switching loss on power devices. A simple and generalized prediction method is used to evaluate its effectiveness. It has two verification tests and one simplified loss calculation model. By a vehicle simulator, it is possible to get the impact of the proposed strategy on loss reduction in standard driving cycles.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"3 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":"133821277","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 forward-pumping circuit is integrated to the 262;uk-derived voltage source inverter (VSI) to achieve a much higher voltage conversion ratio, while avoiding the use of at larger duty ratio of dc-side switch and modulation index of inverter. The proposed inverter can operate oneself naturally to perform capacitive charging in parallel and discharging in series to give a higher voltage multiple, without increasing dc-side voltage stress and sacrificing ac output voltage step-up/down characteristics. Furthermore, one can adopt lower voltage rating devices to further reduce both switching and conduction losses of dc-side switch. The validity of the proposed inverter is be verified by means of some comprehensive results.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"7 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":"115448224","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}

This method supplies more shoot-through time than traditional space vector pulse-width modulation for z-source rectifier. So the proposed method has a wider range of output voltage. Besides, when the output voltage is same, the voltage stress across the switches is lower using modified ZSVPWM than using traditional ZSVPWM, which will decrease switching power losses. This paper mainly analyses the method of modified ZSVPWM and computer simulations are used to verify the proposed method.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"19 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":"114449399","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 addition, in electric vehicle (EV) applications, the IR provides essential information related with regenerative braking capabilities, dynamic charge and discharge efficiencies, or physical degradation of the battery. This work aims to provide the insight details of the IR of a battery under several testing conditions and methods, to present its practical implications on EVs. The experimental tests are carried out on lithium iron phosphate (LFP) batteries ranging from 16 Ah to 100 Ah, suitable for its use in EVs. We study the IR dependency with battery's capacity, SOC and the charge/discharge rate; also, the convenience of using a certain IR measurement method is evaluated. Furthermore, the main results are put into context for practical EV applications, to enhance the design of battery management systems (BMS) in relation with the system's energy efficiency.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"9 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":"115083184","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 first consists in a linear static zeroeth order battery model over a restricted operating window. The second is a non-linear static model, while the third takes into account first- order dynamics of the battery. Simulation results demonstrate that the adoption of a more accurate battery model in the sizing of hybrid ESS's prevents over-sizing, leading to a reduction in the number of cells of up to 29%, and a cost decrease of up to 10%.","PeriodicalId":133160,"journal":{"name":"2014 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"47 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":"123640354","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 main focus lies on how to model components to fit within the framework of convex optimization. The resulting convex models allow the energy-management problem to be formulated as a second-order cone program. Higher levels of a control hierarchy deliver an estimate of optimal costates to a lower level, where the problem is repeatedly solved with the recently developed Embedded Conic Solver (ECOS). The control law is verified and compared with a “standard” control law in simulations.","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":"125975018","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}

However, this technology is not yet completely ready for large scale market. As one of the hurdles, the life duration of PEMFC remains too limited [1]. To overcome this obstacle, the Prognostics and Health Management (PHM) field seems to be interesting. Indeed, the main objective of PHM is the estimation of the time before the failure in order to make the good decisions at the right time for the system to ensure increased durability. The SAPPHIRE EU project aims at developing this field for PEMFC. In a first step, on the prognostics side, it is necessary to develop a way to reproduce the behavior of the stack. A physics-based model seems to be an appropriate way for simulating the behavior. The model developed in this paper [3] [4] is based on an equivalent circuit approach that takes into account low frequencies evolutions through a quasi-static part and fast ones through a dynamic part. This model is developed and validated in order to study its suitability for prognostics purpose.","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":"127413388","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}

Since the application is intended for low-voltage (48V) mild- hybrid automotive traction, an additional major constraint arises: the compactness of the drive related to the size of the DC-bus capacitor.
