EV Wireless Charger

Abstract

As electric vehicles of all sizes become more popular, the demands for convenient ways of powering them grow as well. Wireless chargers have become a preferred alternative to conventional wired chargers for their convenience and safety features. This thesis covers the design and testing of a wireless charger suitable for a small electric vehicle such as an E-bike. An inductive based power transfer is used along with key electronics including inverters, rectifiers, buck and boost converters. Another important element to this design is its ability to use either a DC or AC primary source. This makes the charger more versatile than single source designs by allowing for the choice of a power grid connection or an off-grid power such as through a solar panel. The design process for all components will be discussed and followed with simulation results showing ideal performance. A prototype is also constructed to provide real life analysis of the design and to determine effects of misalignment.
