In electric vehicles, advancements are being done for better performance and safety. The safe operation of the battery pack is one of the critical concerns for the safe operation of an electric vehicle. With the limited number of voltage and current measurement points, the method proposed in this paper ensures safe operation of the battery pack during all the vehicle operating modes, i.e. key on, key off, drive and charge. The method proposed provides an efficient and cost-effective solution to perform contactor weld check operation and diagnosis of short circuit fault during Precharge of the DC bus capacitor. The proposed solution can also be extended to other high voltage applications like static power banks.","PeriodicalId":316015,"journal":{"name":"2019 IEEE Transportation Electrification Conference (ITEC-India)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121225107","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 is known that battery needs to be operated at defined operating temperature range for maximum performance and hence battery thermal management plays a vital role. In a tropical country like India, the major source of heat is the ambient, which in general remains hot (>35°C) throughout the year, summer being exceptionally hot (>45°C) at few locations. To mitigate thermal issues or to design a thermal management strategy, it becomes really important to understand the effect of heat load due to direct sun exposure of electric vehicle battery packs. To evaluate the effects, experiments are done. Further, a methodology is developed to model this solar heating on electric vehicles using StarCCM+ simulation software.","PeriodicalId":316015,"journal":{"name":"2019 IEEE Transportation Electrification Conference (ITEC-India)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126755748","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 introduction of EV fleets for transportation can be considered to be the most applicable solution to promote the electric vehicles and its acceptance from the consumer end. So an optimal allocation of the charging station for the electric vehicles based on the distance and duration from the source to destination and cost needed for charging is proposed in this paper. The Integer linear programming is used for the optimal distribution of electric vehicles to the charging stations available.

Based on ownership and user preferences, light duty and local delivery medium-duty EVs are typically connected to grid distribution networks whereas larger medium duty and heavy-duty EVs are typically connected to distribution or even sub-transmission networks. Challenges with at-scale EVs and charging infrastructure supporting them include interoperability, distribution network upgrades, surge in demand charges, power quality issues, voltage stability, etc. Based on real-world data, steady-state and dynamic assessments of light-duty EV charging with a focus on DC Fast Charging (DCFC) for weak distribution grids is presented. Three main areas of contributions in this paper include - steady state and dynamic power quality measurements and assessments using real world data, transient assessments of light duty EV integration with weak distribution networks (IEEE 13 node feeder system) under grid-connected and microgrid modes, and formulation of an intelligent charging decision algorithm to enable an impact-minimal charging.","PeriodicalId":316015,"journal":{"name":"2019 IEEE Transportation Electrification Conference (ITEC-India)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115996416","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 this paper, we discuss a geometric optics approach to model LIDAR system. The various control parameters of modeling LIDAR system such as cone release angle, the number of rays launched, and angular step size of elevated and azimuthal angle step are discussed. The effect of these control parameters on the error of mapped image are also discussed. The error of the mapped image of the car and pedestrian with 10,000 released rays, cone angle of 5°, and angular step size of 2° was reported with an error of 18% ± 3%.","PeriodicalId":316015,"journal":{"name":"2019 IEEE Transportation Electrification Conference (ITEC-India)","volume":"2023 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116238842","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 provides the buck-boost conversion features along with improved profile of the source current and hence lower source current ripple content. Establishment of the elaborate time-domain analysis is also done for understanding the performance traits exhibited by the proposed converter along with converter component design equations. The proposed converter control scheme yields two different circuits for which the corresponding state-space models are derived, and small-signal analysis is performed to obtain the relevant transfer functions. Using these transfer functions obtained, a digital voltage-mode controller has been designed. To demonstrate the buck-boost conversion along with low source current ripple profile, a 36 Watt, 50 kHz laboratory prototype converter is designed to test the proposed converter’s power supplying capacity at constant load voltage. A 24 V battery input voltage, 15/36 V as load voltage is considered in the experimentation. The effectiveness of the performance of the proposed converter in terms of reduced source ripple content, voltage buck-boosting feature is performed on simulation and also validated experimentally.","PeriodicalId":316015,"journal":{"name":"2019 IEEE Transportation Electrification Conference (ITEC-India)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114274592","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}

Split phase machine is a multi phase machine with two-three phase windings phase shifted by 30° which helps in reduction of sixth harmonic torque pulsations. In this paper, two series connected split phase synchronous motors connected with proper phase sequence are supplied with single six phase VSI. The same is modeled and is implemented experimentally. Series connected synchronous motors are difficult to operate under open circuit fault. Post fault MMF (magneto-motive force) equations are developed to obtain rotating magnetic field with constant magnitude.
