But the main bottle neck for such deactivation process is excitation of mechanical systems which affects the reliability of sensitive mechanical components. Hence the investigation of cylinder deactivation condition with components modelled with sufficient accuracy will be beneficial for the design of the system. The diesel engine generator system can be simplified as a 7 inertia-6 stiffness system. The mechanical driveline system subjected to engine cylinder deactivation have torsional stresses developed between individual components. An electrical control solution is developed to alleviate torsional stresses. The proposed solution damps the torsional oscillation and hence improves the reliability of the system under engine transients.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"1 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":"123255225","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 proposed multilevel topology reduces the voltage stress across the switches which enables utilizing eGaN HEMT technology in the powertrain of the EVs.

Two approaches for solving a mixed-integer energy flow optimization problem using nonlinear and linear programming algorithms and their implementation in MATLAB/Simulink will be proposed. The use of the developed simulation model for energy management systems allows the analysis of power net designs, the validation of safety requirements and the design of system fault reactions.

Optimizing the control and operation of the APM is an important component of minimizing vehicle energy consumption. Characterizing the performance of the APM requires extensive testing of APM under different operating conditions. However, in the state-of-the-art experimental validation testing using industry standard modeling practices, addressing uncertainties in the test results is not very common. A consequence of this shortcoming is the propagation of uncertainty from test to simulation, which can cause simulated results to diverge significantly from real world performance. In this paper we present test procedures and results for a Delphi Auxiliary Power Module (APM) that was installed in a 2011MY Chevrolet Volt. Experimental uncertainty in the measurand of efficiency is modeled using Scheffe confidence intervals as a function of APM output current. Uncertainty is then propagated through a vehicle fuel economy simulation to understand the role of APM experimental uncertainty in vehicle fuel economy prediction.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"68 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":"116976632","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 can recharge EVs in direct current in a short period of time. In recent years, the increasing penetration of EVs and their charging systems are going through a series of changes. This paper addresses the design of a new DCFCS for EVs coupled with a local Battery Energy Storage (BES). DCFCS is equipped with a bidirectional AC/DC converter for feeding power back to the grid, two lithium batteries and a DC/DC converter. This paper proposes an optimal size of the BES to reduce the negative impacts on the power grid through the application of electrical storage systems within the DC fast charging stations. The proposed solution decreases the charging time and the impact on the low voltage (LV) grid significantly. The charger can be used as a multifunctional grid-utility such as congestion management and load levelling. Finally, an optimal design of the DCFSC has been done to evaluate the feasibility and the operability of the system in different EVs load conditions.","PeriodicalId":228690,"journal":{"name":"2017 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"49 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":"134484150","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}
