Electricity Consumption and Battery Lifespan Estimation for Transit Electric Buses: Drivetrain Simulations and Electrochemical Modelling
Electricity consumption and battery lifespan estimation for transit electric buses: drivetrain simulations and electrochemical modelling by Ana¨ıssiaFranca B.Eng, University of Victoria, 2015 A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of MASTER OF APPLIED SCIENCE in the Department of Mechanical Engineering c Anaissia Franca, 2018 University of Victoria All rights reserved.

The underlying goals of the project were to develop analytical tools to support the integration of battery electric buses. ECONS-M projects the operating costs of electric bus and the potential emission reductions compared to diesel vehicles for a chosen transit route. CFM aims to predict the battery pack lifetime expected under the specific driving conditions of the route. A case study was run for a transit route in Victoria, BC chosen as a candidate to deploy a 2013 BYD electric bus. The novelty of this work mainly lays in its application to battery electric buses, as well as in the coupling of the ECONS-M and the electrochemical model to predict how long the batteries can last if the electric bus is deployed on a specific transit route everyday. -

Policy imperatives and government support could ensure three-fold volume growth by 2020, which would make China half of this developing global market. New entrants are proliferating, with few clear winners as yet, but we conclude that Yutong and BYD have the scale of NEV sales today to support Buy ratings. ________________________________________________________________________________________________________________ Deutsche Bank AG/Hong Kong Deutsche Bank does and seeks to do business with companies covered in its research reports.

Analysis of the Reduction of CO2 Emissions in Urban Environments by Replacing Conventional City Buses by Electric Bus Fleets: Spain Case Study
Article Analysis of the Reduction of CO2 Emissions in Urban Environments by Replacing Conventional City Buses by Electric Bus Fleets: Spain Case Study Edwin R. Grijalva 1,2 and José María López Martínez 1,* 1 University Institute for Automobile Research (INSIA), Universidad Politécnica de Madrid, 28031 Madrid, Spain; [email protected] 2 Facultad de Ciencias de la Ingeniería e Industrias, Universidad UTE, Bourgeois N34-102 & Rumipamba, Quito 171508, Ecuador * Correspondence: [email protected]; Tel.: +34-913-365-304 Received: 14 December 2018; Accepted: 29 January 2019; Published: 7 February 2019 Abstract: The emissions of CO2 gas caused by transport in urban areas are increasingly serious, and the public transport sector plays a vital role in society, especially when considering the increased demands for mobility. New energy technologies in urban mobility are being introduced, as evidenced by the electric vehicle. We evaluated the positive environmental effects in terms of CO2 emissions that would be produced by the replacement of conventional urban transport bus fleets by electric buses. The simulation of an electric urban bus conceptual model is presented as a case study. The model is validated using the speed and height profiles of the most representative route within the city of Madrid—the C1 line. We assumed that the vehicle fleet is charged using the electric grid at night, when energy demand is low, the cost of energy is low, and energy is produced with a large provision of renewable energy, principally wind power. For the results, we considered the percentage of fleet replacement and the Spanish electricity mix. -

Alberto Faveto February 2021 Acknowledgment I would like to express my special thanks of gratitude to my supervisor Prof. Giulia Bruno as well as Dott. Alberto Faveto for giving me the opportunity to make research on this interesting subject and for providing guidance and help throughout this research. I am also thankful to all my friends who shared their supports with me all the time. Seren, Nogay, Musa, and Togrul are the ones who deserve a special thanks for being always there for me. Lastly, I would like to acknowledge with gratitude, the support, and love of my family. 1 2 Abstract Nowadays, the automotive industry faces one of the biggest transformations ever. As the concerns about greenhouse gas emissions and global crude oil demand grow, the automotive industry undergoes a change towards the use of electric vehicles (EVs) over traditional internal combustion engine vehicles. For a greater revolution, EVs need to point out issues such as long charging times, insufficient charging infrastructure, low battery performance, high price, fleet electrification, as well as powering renewable energy-based charging grids. As a result of these problems, vehicle manufacturers have started to investigate and invest in more cost-efficient and innovative solutions to engage with the issues related to using electric vehicles. For instance, in order to overcome the long battery charging times, the battery swapping systems (BSS) have been introduced. -
