Upcoming Webinars

Advanced Health-Conscious Fast Charging Schemes and Battery Management Systems for Autonomous E-mobility

Sponsored by the IEEE Power Electronics Society Technical Committee on Sustainable Energy Systems

Presenter:  Sheldon Williamson, Ontario Tech University, Canada
Date:  Tuesday, June 15, 2021, 11:30 am New York Time (Please note new time)

Abstract: It has become imperative to find a solution to manage energy production and usage accurately, especially within the context of future electric energy storage for aerial vehicles and autonomous e-transportation systems. Enhancing the life of Lithium-ion (Li-ion) battery packs has been the topic of much interest. In this framework, the role of on-board cell voltage balancing of Li-ion batteries will be highlighted in this talk. This is a very important topic in the context of battery energy storage cost and life/state-of-charge, SOC/state-of-health, SOH monitoring. Li-ion batteries, although popularly proposed for electric transport, have been highly uneconomic for energy storage, overshooting cost requirements by a large margin.

This talk will also introduce a first-of-its-kind closed-loop cell charge (voltage) balancing and extreme fast charging technique. The technique uses instantaneous cell voltage and/or temperature rise (ΔT) as a control parameter. Existing charging techniques for Li-ion batteries use a largely open-loop approach, where the charge profile is pre-decided, based on apriori knowledge of cell parameters. There is a need for closed-loop charging techniques that use instantaneous cell voltage and/or temperature to modulate the charging current magnitude. This seminar addresses this gap by proposing for the first time ever a constant-temperature constant-voltage (CT-CV) charging technique, considering cell temperature as a key degradation metric. This talk will also establish the benefits of the proposed CT-CV charging at cell level and increases the possibility of extending it to the pack level by integrating it with battery management systems.

Testing Inverters using Electric Motor Emulators:  Benefits, Challenges

Sponsored by the IEEE Power Electronics Society Technical Committee on Electrical Machines, Drives and Automation

Presenter:  Dr. Uday Deshpande, D&V Electronics, USA
Date:  Tuesday, June 29, 2021, 11:00 am New York Time

Abstract: In this webinar, the presenter will his experience and thoughts on the use of electric motor emulators for testing and validation of inverters.

The first part of the presentation will cover an overview of typical test and validation elements and steps and some of the trends considering increasing electrification and growth of electric vehicles. The second part of the presentation will discuss the essential elements of an electric motor emulator, how it can be used for testing an inverter in lieu of a conventional dyno, typical tests that can be done using an emulator test system including performance, durability, environmental, that address functionality and compliance. The third part of the presentation will cover challenges and considerations that need to kept in mind as people consider using emulator-based test systems. We will look at motor models and real-time implementation, considerations to ensure high fidelity representation of motor behavior, means and mechanisms to study faulted behaviors. Through this webinar, the audiences can expect an in-depth overview of this fast-growing approach to improve test efficiency and effectiveness and spark ideas and discussions to continuously improve design and development cycles.
