John Rizzo, Chief Strategy Officer, InductEV

The race to net zero carbon emissions depends critically on the reduction of carbon from the transportation sector.   Inductive wireless charging is a key technology to help accelerate battery electric vehicle charging but do so in a way that doesn’t put additional pressure on the grid, during peak times, when electricity is produced with fossil fuels. The traditional approach of depot wired charging of commercial fleets is counter-productive to carbon reduction and on-route wireless charging is the solution.

Dr. Alexander Kuhl, Director of Research, Center for Electromechanical Engineering

Dr. Kuhl will give a European perspective on the progress of Electrified Roadway Systems (ERS) projects. He will briefly introduce the Friedrich-Alexander-University (FAU) and the Mechanical Engineering Institute for Factory Automation and Production Systems (FAPS) of the School of Engineering.  He will review the currently running projects related to ERS, and especially those connected to E|Road Center Bavaria. This will give attendees an opportunity to compare what is the focus in a European context and how that compares to similar initiatives in the United States.

Scott Trimboli, Associate Professor of Electrical and Computer Engineering, University of Colorado Colorado Springs and Greg Plett, Professor of Electrical and Computer Engineering, University of Colorado Colorado Springs

Battery packs require careful supervision and management to ensure safety and longevity, and to maximize performance. State-of-art battery-management methods generally use empirical circuit-based models of battery cells to guide their estimates and decisions. However, these models cannot describe the electrochemical state inside the battery cells, and it is precisely this state that indicates unsafe operating conditions, predicts rates of cell degradation, and limits performance. Physics-based models of cells can instead be used with battery-management methods to estimate this state and enhance operation, but there are a number of challenges that impede using these models in practical applications. This presentation proposed methods to overcome these challenges. Download the PDF

Khurram Afridi, Cornell University

Road transportation, which accounts for 22 percent of greenhouse gas emissions, is undergoing a major transformation with the advent of ridesharing, autonomous driving, and vehicle electrification. Collectively these technologies, in conjunction with renewable sources of electricity, have the potential to dramatically reduce the negative impact of road transportation on the health of the planet. The successful convergence of these technologies will require electric vehicles that are low cost and fully autonomous. These attributes can be realized through dynamic wireless charging. However, this will require wireless charging technology that is well beyond current capabilities, and opens new areas of research related to power and transportation infrastructure. Using examples from his current research on capacitive wireless charging (as opposed to the more common inductive techniques), which leverage very high frequency power electronics, Dr. Afridi’s presentation highlighted several opportunities and challenges in dynamic wireless charging of electric vehicles.

Rick Meyer, Western Michigan University

Power system modeling and optimal control for electric transportation applications involves switched systems, i.e., the system has components with dynamics that change based upon the direction of power flow. Control of switched power systems typically requires consideration of integer variables associated with the directions of power flow in the system, requiring specialized numerical solvers. Rick Meyer presented power flow-based component modeling that treats each component as a power converter with some efficiency. Models are oriented toward control development and can include dynamics at different time scales. Components are connected together into systems using power as a connection variable. Further, to solve the power system management control problem using traditional solvers rather than specialized ones, an embedding method is described that embeds the original switched problem into a traditional problem. Application of the power system modeling and embedding method for switched system control will be presented for ground vehicles and hybrid electric propulsion for general aviation aircraft.
