This is largely due to air quality and environmental laws, as well as customer demand and reducing price of rechargeable energy storage solutions. Furthermore, considerable advancements have made many storage devices, particularly those in Li-ion family, suitable for automotive use. As more lithium batteries powered vehicles become operational around the world, their contribution in traffic incidents are expected to increase. The risks associated with conventional automobiles are well known; nonetheless, it will take time and education to achieve this comfort level for electric vehicles. This article examines the issues that the electric vehicles sector has in terms of high-density lithium battery technology. The study then delves into the role of original equipment manufacturer and cell makers in ensuring a safer future for electric vehicles.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"23 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":"125462500","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}

Thermal design of a battery pack is one of the critical and time-consuming topics during development, as the designer needs to perform multiple tasks - select the thermal concepts, perform simulations, and evaluate them against the requirements within the given boundary conditions. Therefore, transforming the requirements and cell thermal characteristics into inherent thermal design metrics will help the design engineer to objectively approach the design problem and simplify the evaluation process. The metric-based approach is effective in choosing a thermal concept and help evaluate the extent to which each of the requirements are met and achieve trade-offs. An equivalent thermal conductance can be a suitable design metric to derive from the thermal requirements of a battery. The metric-based approach will accelerate the design process and can be used to objectively track effectiveness of future thermal design iterations.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"52 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":"126569720","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 passive system continuously monitors the rate of change of frequency and islanding condition is detected whenever it crossed a preset threshold value. Since transients in grid may also results in frequency deviation a higher threshold is desirable which increases the non-detection zone for passive islanding technique. An active islanding detection scheme is proposed where a linearly time varying reactive power in injected following an islanding detection by passive islanding method. Unlike conventional active islanding technique where change of frequency is compared with a threshold value, the proposed scheme evaluates correlation between the estimated rated of change of frequency (ROCOF) and measured ROCF. The value of this correlation function provides the threshold value for detection of islanding condition. Since the value of this correlation function in independent of the magnitude of the reactive power injection the proposed technique can work with lower injection of reactive power and hence distortion in power quality introduced by the proposed active islanding technique will be smaller","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"35 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":"124132395","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 motivation behind this article is the less or no visibility of electric scooters in hilly region cities of India. The information of hill angle is essential for road load analysis of hilly roads. This paper presents a cost-effective and straightforward procedure to find the road grade from the data (speed, altitude, time, distance) collected from an ICE scooter using a GPS-based app on a smartphone in Shillong city. Further, from the data collected, the road load characteristic is studied for synthesizing the power and torque requirement of electric scooters for such hilly roads. The results show that the torque demand increases with the increase in the hill angle value, leading to trade off some scooter speed for a given power. For an electric scooter to be suitable for such an aggressive road, it should have a high-power motor with a high current rating and high current capacity battery banks.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"31 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":"123292984","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 vector control scheme is used to operate the machine in both motoring and generating mode. During braking operation, the PMSM is operated in generating mode to obtain the required braking torque. The power developed by PMSM during braking action is absorbed by a supercapacitor through a bidirectional synchronous buck converter. The power stored in the supercapacitor during braking is used to drive the motor or to charges the battery as per the operating condition of the EV. In case the supercapacitor is fully charged during braking operation, the battery is directly charged with the maximum allowable charging current while dissipating the rest of the power in a braking resistance. Since the fluctuating component of power generated during braking or rapid acceleration is mostly absorbed or delivered by the super-capacitor, the battery supplies a steady power which increases the life expectancy of the batteries. The performance of the proposed scheme is validated through a simulation study in Matlab/ Simulink.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"1 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":"131773468","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}

Input current drawn by these boost stages is high at higher power rating, as these stages process power from a low input voltage. This results in very high power loss in the active elements of the inverter, hence lowering efficiency of the system. In this paper, an Interleaved Switched Boost Topology with ‘n’ phases (n-phase ISBT) as a front-end dc-dc boost stage is proposed to deal with the abovementioned limitation. In order to facilitate the ‘n’ phase interleaving, a novel Pulse Width Modulation (PWM) scheme is proposed. Proposed converter in its steady-state is analyzed with various operating modes and gain characteristics. Steady-state operation of ISBT with two interleaved phases is validated using PLECS simulation as well as through experiments on an experimental prototype.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"127 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":"134015415","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}

Range primarily is defined by the battery pack's available energy. However, considering the same vehicle, the range depends on the user or the driving pattern. Recent controversies regarding range claimed by the EV manufacturers have raised many questions. The claimed range of any EV is usually based on standard drive cycles. Some of the standard drive cycles need to be modified as the customer requirements are changing. Driving pattern also varies depending on the vehicle segment. At the same time in a country like India as driving cycle and pattern varies across demography, how a new standard driving cycle can be generated is a question to be answered. In order to predict the driving range of any EV, as well as the battery lifetime and warranty of battery pack, real world driving profile needs to be considered. Therefore, selection of right driving profile is crucial for EV. In this review article, the generation of driving profile and its different characteristics, especially for EVs, are discussed in detail.","PeriodicalId":162261,"journal":{"name":"2021 IEEE Transportation Electrification Conference (ITEC-India)","volume":"17 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120837372","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}

Zero-emission powertrains like Battery Electric Vehicles (BEVs) and Fuel Cell Electric Vehicles (FCEVs) are being evaluated and implemented in various vehicular segments in India. Already the two-wheeler, three-wheeler and small passenger car segments are moving swiftly towards electrification. Due to the battery capacity limitations of BEVs and the resulting range as well as charging issues, FCEVs are of increasing interest for vehicle applications with long driving ranges. The presented study targets to find an optimized zero emission powertrain solution for a 42-ton truck for the Indian market. The Heavy Commercial Vehicle (HCV) segment in India has requirements like long driving range, low cost of ownership and equivalent payload carrying capacity/space compared to conventional vehicles. An evaluation of FCEV vs. BEV is done for the selected truck by performing powertrain simulations considering Indian driving conditions using GT Suite. With the longitudinal dynamics simulation models developed in GT Suite, components sizing of the powertrain subsystems like the Fuel Cell System (FCS), battery system etc. are performed for the FCEV and BEV architectures.
