Due to the varying complexity to match the balance between economics of scale and economics of scope in the development of electric vehicle components, the role played by driving cycles in determining lifetime, performance, thermal behavior is highly substantial. Federal Test Procedure 72 (FTP 72), FTP 75, Highway Fuel Economy Test (HWFET), and New European Driving Cycle (NEDC) are a few driving cycles used for emission and range tests for light duty vehicles. This paper discusses a methodology to derive driving cycles from the road load data. A large quantity of data collected from multiple trips are combined and compressed to make a driving cycle that represents the trip characteristics. It is important that the final compressed cycle of short duration should represent the complete data collected from the road. The recorded data were divided into several micro-trips based on the stops. The algorithm then calculates 17 parameters including average speed, maximum speed, average acceleration, and dynamic index for each micro-trip. The candidate micro-trips for final compressed driving cycles are selected comparing the weighted sum of the parameters. Statistical parameters for the collected data are compared and the final driving cycle is created to make sure that it best represents the actual collected data. The driving cycles derived are typically limited to 3600 to 5400 seconds and meticulously customized to cover varied applications of city, highway, and countryside usages. The paper also covers the electric vehicle simulation results of the generated load cycles using a forward-facing simulation model. Test bench-based durability studies with the drive cycle is not included in the paper","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115485160","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}

Pedestrian detection is an important segment of object detection, which is one of the the trending issues of computer vision and self-driving cars. Deep learning techniques furnished significantly enhanced results in the area of pedestrian detection. However, most of the literature reveals that the models used for addressing either speed or accuracy. In this paper, we addressed the speed and accuracy in pedestrian detection for autonomous cars. Manual inspection is replaced with a deep learning method, augmented images are exposed to You Look Only Once version 5 (YOLOv5) with activation function which creates a tradeoff between speed of detection and accuracy. This model is the best influential object detection algorithm at the moment to detect pedestrians in public places. The proposed pedestrian detection model is trained with the dataset of 'CityPersons' with 2975 images out of total 5000 images. The experimental analysis proves that the proposed algorithm remarkably improvises the detection speed with 0.011sec/image which can apply to the real time environment with a 46.2% Miss-Rate (MR) on highly occluded city persons dataset among various occlusion levels of it.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129860330","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 presented charging system employs a single switch positive output bridgeless Cuk high power factor converter (HPFC) at the front end and a full bridge current doubler circuit at the back end, to carry out ripple free charging of the battery. Unlike conventional bridgeless Cuk HPFCs, the presented bridgeless Cuk HPFC ensures zero circulating current through antiparallel diode of the switch, zero capacitive coupling loop current, positive output voltage polarity, and incorporates single gate drive circuitry. Further, the current doubler configuration at the battery end, greatly simplifies the transformer design, and reduces the diode conduction losses while maintaining low current ripples in the charging current. Considering these advantages, the charger topology is comprehensively analyzed, and its performance is tested under various operating conditions. Finally, the relevant results are presented for performance verification.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116974157","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}

Inappropriate placement of CSs may adversely affect the distribution system in terms of losses, thermal loading, and power quality, increasing operating costs, etc. A CS does not continuously operate at its full capacity, and therefore, the unused capacity of CS can be used to provide reactive power support. The paper proposes the utilization of unused EV chargers as static synchronous compensators (STATCOM) to enhance system performance. This paper aims to optimally locate the EV CSs with the objective of system power loss minimization utilizing unused chargers as STATCOMs. To evaluate the effectiveness of the proposed approach, two different studies are conducted. The first case deals with the planning stage to find optimal bus locations for CSs. The second case conducts the operational performance in which an optimal power flow study is performed with the different number of available unused chargers at random locations within the optimally selected CSs. The proposed work is validated on the modified IEEE-33 bus radial distribution system.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126979783","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 noise and vibration behavior in hybrid vehicle is significantly different from the conventional vehicle. In conventional vehicles, certain noise phenomena are masked by the engine noise. However, when the combustion engine is turned off in hybrid vehicle, these noise components can become dominant and annoying. While driving, the low frequency interior noise below 2000 Hz causes the main component that irritates the auditory acoustic sense. In order to remove this low frequency noise, passive noise control methods were used using sound absorbing materials or isolating the noise source. However, it is found that the sound absorbing materials are effective only for high-frequency noise compared to low frequency noise. The present work deals with the sound absorption properties of open-porous Polylactic acid (PLA) material structures that were produced using 3D printing technology. The material's ability to damp sound was evaluated based on the normal incidence sound absorption coefficient and the noise reduction coefficient, which were experimentally measured by the transfer function method using an acoustic impedance tube. The present investigation showed that the 3D printed openpore structure are efficient to reduce the noise by absorbing sound.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127092996","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}
