Plenary session

Plenary lecture "Vehicle electric drivetrains - evolution of technology" will be presented by prof. Lech M. Grzesiak

Vehicles with electric drive were built and used more than 100 years ago, before the automotive market got dominated by internal combustion engine vehicles. The production of electric drive vehicles was virtually stopped when Ford began making cars with internal combustion engine (early XX century). The new era of electric cars is the beginning of the 21st century. At first, hybrid cars appeared. During the last few years there has been a definite trend towards development of electric vehicles (EV). Electric drivetrains consist of an electric energy store (source of electric power), an electric drive, a power electronic converter and a control system allowing for the regulation of the moment and speed of the drive motor.

The lecture will be an overview of electric drivetrains in manufactured EVs. The current state of scientific research related to the development of new technologies in the area of electrical drives, power electronic converters and electrochemical energy sources will be presented.

Solutions with high-speed machines and mechanical transmissions will be discussed, as well as direct drives without additional mechanical transmission (eg drives placed in wheels). We will present advanced control structures and methods that provide precise traction control (analogy to ABS and DTC), energy flow management during engine and generator operation, and adaptation of on-board systems to use fast charging stations. Also converters characterized by high efficiency and overloading capability, which ensures high dynamics of the drive system and specific features of the electric machines will be presented.

Professor Lech M. Grzesiak is a graduate of the Electrical Department of the Warsaw University of Technology, a professor at the Institute of Control and Industrial Electronics. He is a Dean of the Faculty and Head of the Electric Drives Unit. Previously, he was the Deputy Director for Science (1991-2008), and then the Director of the Institute of Control and Industrial Electronics (2008-2012). He was Co-Director of the Center of Excellence (2003-2005) - "Power Electronics Intelligent Control for Energy Conservation" - PELINCEC. For many years he was the auxiliary editor in IEEE Transaction on Industrial Electronics, and currently in IEEE Transaction on Industrial Informatics. He completed long-term internships at ETH Zuerich and RWTH Aachen. He is a member of many international and national scientific organizations. In 2003, he obtained the Senior Member degree in IEEE.

His research and publications deal with the issues of electric and unconventional drives control, converter power generation systems, and more recently the use of artificial intelligence methods in drive systems and power electronic converters. He is a co-author of over 40 patents and author and co-author of over 200 scientific papers. He is a co-author of the academic textbook "Control of electric drives".
