ABSTRACT:

Range anxiety is a key reason that consumers are reluctant to embrace electric vehicles (EVs). To be truly competitive with gasoline vehicles, EVs should allow drivers to recharge quickly anywhere in any weather, like refueling gasoline cars. However, none of today’s EVs allow fast charging due to the risk of lithium plating, the formation of metallic lithium that drastically reduces battery life and even results in safety hazards. In this talk, we present a new approach enabling 10-minute fast charging of energy-dense Li-ion batteries in any temperatures (even at -50 °C) while still preserving remarkable cycle life. We further show that fast rechargeability is an economical answer to mass-market EVs, making possible a vehicle battery costing only $3,500 while eliminating range anxiety. Finally, we shall discuss why any fast charging solutions for EVs must be evaluated under three metrics simultaneously: charge time (<10 min), specific energy acquired by fast charge (>180 Wh/kg), and cycle number (>1000) under the fast charge condition.


ABOUT THE SPEAKER:

Dr. Chao-Yang Wang, Academician of National Academy of Inventors, is William E. Diefenderfer Chair Professor of Mechanical, Chemical, and Materials Science & Engineering at the Pennsylvania State University. He has 220+ journal publications, 34,000+ citations, an H-index of 101. He holds over 140 patents and has published two books, “Battery Systems Engineering” by Wiley and “Modeling and Diagnostics of Polymer Electrolyte Fuel Cells” by Springer. His work on all-climate battery (ACB) was selected by 2022 Winter Olympic Games to power electric vehicles serving the Games, as well as adopted by several carmakers. His latest inventions on fast charging batteries (FCB) and thermally modulated battery (TMB) were highlighted by journals Nature and Science as well as covered by mainstream media such as USA Today, Popular Mechanics, BBC, The Guardian, AFP, Daily Mail, etc. Dr. Wang’s expertise covers the transport, materials, manufacturing and modeling of batteries and fuel cells.

Chief Executive Officer, Siemens Mobility Hong Kong


DATE:

22 MAR 2021 (MONDAY)


TIME:

19:00 - 20:00


VENUE:

CBA, G/F CHOW YEI CHING BUILDING & VIA ZOOM

ABSTRACT:

With the mega trends such as urbanization, growing population, climate change, the demands for better transportation systems and services globally are rising. Thanks to the advanced development of digital and platform technologies, digitalization plays an increasingly important role in shaping the future of mobility industry, which is experiencing a paradigm shift.

In the process of digital transformation, a key question is not only about the technology itself, but also about people. To shape the future of mobility, how we can enable and empower different groups of people in the meantime? How can we build a more people-friendly, seamless, shared, reliable and sustainable transportation ecosystem that takes cares the first mile and the last?

As the CEO of Siemens Mobility Hong Kong, Mr. Brauner will share the latest industry trends and experience as well as smart mobility applications globally and locally from a people perspective.


ABOUT THE SPEAKER:

Peter is an expert in the transportation sector for 30 years. He has degrees in electrical engineering and economic psychology, because for him, technology and people belong together, especially when it comes to digital transformation and the application of artificial intelligence.

By living and working throughout Europe, America and Asia, he became passionate about diversity and leveraging cultural synergies for the development of disruptive innovations.

As the CEO of Siemens Mobility in Hong Kong, he is working with his team and local partners to turn Hong Kong into a smart city.

Holding patents by himself, he is always looking for bright ideas and supports talents and their visions. And still today he is dealing with latest technologies and is using AI for developing apps by himself, just for fun.


REGISTRATION:

Professor Kay W. Axhausen


DATE:

10 March 2021 (Wednesday)

ABSTRACT:

An active GPS tracking study gave the IVT ETH Zürich in collaboration with the WWZ, University Basel the chance to start a panel to observe the impact of the pandemic and of the local administrative measure on travel behaviour. The sample size varied between 1300 and 500 over the course of the last year. The presentation will address the changes in immobility, mileage, mode choice and activity space. Due to the socio-demographic information available from the fall 2019 and further updates in 2020 these analyses will be broken down the level of accessibility of the home location, work status, income, gender and age. It will highlight the rebound effects in VMT and trip making of working from home.


The second part of talk will discuss the longer term impacts of the pandemic and how this might impact the transport and settlement systems in the months/years to come. The basic dilemma of transport policy making will not broken up by its impacts.


ABOUT THE SPEAKER:

Dr. K.W. Axhausen is Professor of Transport Planning at the Eidgenössische Technische Hochschule (ETH) Zürich. He has been involved in the measurement and modelling of travel behaviour for the past 37 years contributing especially to the literature on stated preferences, micro-simulation of travel behaviour, accessibility, valuation of travel time and its components, parking behaviour, activity scheduling and travel diary data collection.Current work focuses on the agent-based micro-simulation toolkit MATSim (see www.matsim.org ). The current GPS tracking study (https://ivtmobis.ethz.ch/mobis/covid19/en/) is part of his work on modelling the COVID19 pandemic.
