Bidirectional inductive contactless energy transfer system topology for electric vehicles

Inductive Contactless Energy Transfer systems (ICET) are becoming commonplace in electrical and electronics equipment. Increased growth of interest in electric vehicles EV and renewable energy sources significantly changed the approach to vehicle. Not only is EV battery pack a vehicle for the drive tank, but it´s also power grid´s distributed energy storage. To ensure the automation of the flow of energy best fits is inductive contactless power supply system with bi-directional energy flow. These systems are based on inductively coupled resonant circuits and offer many properties that affect the high efficiency energy transfer. The paper presents selected simulation studies of the ICET system with power up to P = 100 kW, in use for electric vehicles.
