The CIPF method can realize the bi-directional and active-tracking elimination of harmonics from the nonlinear load and the generators at the source-side. The three-phase circuit and mathematical models of the CIPF system are established. By means of the theoretical analysis on the harmonic distribution characteristics, the operating mechanism of the CIPF method is revealed. To further improve the filtering performance, an advanced control strategy to replace the conventional resistive control is designed. Finally, based on the prototype system in the laboratory, the proposed CIPF system applied in the SPS is validated.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127201849","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 integrated converter, capable of operating in both traction and charging modes, can be reconfigured as an interleaved boost or a dual active bridge (DAB) converter. The existing contactors of the battery management system (BMS) are used for reconfiguration between the boost and DAB modes. To maximize overall power conversion efficiency during traction operation, the converter is dynamically reconfigured to operate in the mode with highest efficiency at the present operating point. A switching transition control approach is developed for fast and seamless switching, ensuring zero-voltage turn-on and zero-current turn-off of the BMS contactors. The smooth transitions minimize switching-induced degradation of the BMS contactors, and allow uninterrupted power delivery during mode transitions. The experimental results of the prototype are presented to verify the functionality of the proposed control approach.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127333780","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 major concerns about a BEV battery pack is the process of aging, and the loss of driving range over the years of utilization. The phenomenon of capacity loss of lithium-ion batteries has been under scientific investigation for many years. Meanwhile, it is commonly accepted that the effects of temperature play an important role in this context [1–6]. Moreover, among others, the dynamic temperature behavior dictates the performance of the battery pack. The dimensioning of the cooling plays an important role in this manner [7]. In the early concept phase of a BEV and in this case the battery pack, many decisions must be made which have a major influence on the aforementioned aspects. Normally, simulation models are created to answer essential initial questions and to assist the cell selection process, as well as more general conceptual questions regarding the whole battery pack. More complex simulation models like 3D electrochemical or electrothermal finite element models require a great deal of computational power, especially when transient simulations are needed to answer important questions [8]. Therefore, a method is developed, which can speed up those simulations by a factor of more than 1,000 without losing to much accuracy of result. By creating metamodels with standardized pre-simulations of the models, the dynamic behavior can be emulated. It is shown, that by evaluating these meta-models in sequence, transient simulations can be executed without the time-consuming solving process of finite element models. Hence, it is possible to investigate a multitude of possible configurations in a much shorter and less computational expensive way.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133615683","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 converter is described in a sum and difference (ΣΔ) framework. It is shown that the formulation is useful to model the inverter and derive design-specific equations. The Σ component is responsible for the inductor current, i.e. the power flow, and the Δ component is used to balance (or unbalance) the DC-link capacitor voltages. It is shown that there are cross-coupling terms between the Σ and Δ axes that can be compensated. The proposed model is validated using high fidelity simulations with a proportional-integral controller. Two- and three-level converter operation is shown and it is proven that the passive components can be reduced by 50% to 75% using three-level operation without affecting the control performance. The control is verified by introducing load current and DC voltage steps.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133103770","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 order to estimate the rotor speed, a new back-electromotive-force (back-EMF) based-model reference adaptive system (MRAS) estimator is proposed. The new back-EMF MRAS is independent from the stator resistance and stator inductance parameters. Hence the proposed scheme is immune to these parameters variations. It also is robust against inverter nonlinearity and shows consistency at starting from standstill. The proposed scheme has been experimentally implemented and tested on a 19-kW induction motor (IM), of a type used for the automotive industry for EV applications. A comparison is carried out between the performance of the conventional and the proposed back-EMF MRAS. Tests include sensitivity to stator resistance variation and capability to start from standstill. Experimental results show the improved performance achieved using the proposed sensorless control scheme and its suitability for EV applications.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115744332","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 relies on a manual, or robotized manual transmission together with a BLDC motor coupled at the output for filling the torque hole between gear changes. In order to keep manufacturing cost low and improve commercial attractiveness, it incorporates gearshift strategies that deliver high-quality gear shifts. A deliberate downsizing of componentry is implemented as far as possible to reduce cost, and control strategies are employed to exploit the maximum potential of the architecture using methods including torque-fill, ICE-assist, and ICE start-stop. The architecture is developed in simulation using an existing conventional platform to investigate system properties and their effect on performance. In particular, we discuss the gear-shift control algorithm design. Until the cost of full hybrids and fuel cell vehicles is significantly reduced, such a mild hybrid may have the potential to provide the right cost-benefit balance to achieve strong market penetration.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116487912","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}
