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.
