| Main Objective: Inductive power transfer (IPT) technology solves both the limited range of an EV and electric hazard risks associated with power cord chargers. An EV IPT system enables the transfer of energy without any contacts between the off-board and on-board sides by means of a loosely coupled transformer, also known as Magnetic Coupler (MC). Each side of the MC (power pad), comprises one or more coil structures magnetically linked with the coils in the opposite pad. The benefits of such configuration include galvanic isolation, operation under different weather conditions and energy transfer capabilities with a fixed (static) or moving (dynamic) receiver. The purpose of this project is to investigate how to maintain the air gap between transmitter and receiver pads of the MC to a minimum and independent of the vehicle type by using the wheels for an embedded IPT system and making them as an intermediary stage between the off-board and on-board sides. The development of new airless tire designs with sustainable materials (glass fiber and resins), like the Uptis model (Michelin), strengthen the viability and applicability of in-wheel IPT (inWIPT) systems. These new airless tire designs also eliminate the risk of pressure increase in the tire caused by Joule losses in the receiver coils within the tire. In addition, the aluminium rim shields the leakage flux lines above the receiver coils and avoids the use of additional shielding. Moreover, the proposed inWIPT technology would offer several installation configurations to mitigate stray fields and tolerance to horizontal displacements or other misalignments. |
