Abstract

This paper proposes the design of dual-output wireless power transmission including backup mode operation for electric scooter applications. The study considers two modes of power transmission, where the power is delivered either from the adjacent battery or from the main power source to charge the scooter battery. Three inductive coils and three sets of full-bridges inverters are implemented in the circuit. The study first evaluates the geometrical structures of three inductive coils that include one transmitting coil and two receiving ones. The system is designed to operate at two frequencies to achieve different modes of operation using the same compensated capacitors. To validate the effectiveness of the propose configuration, the hardware realization is made with an achievement of efficiency of 92.7 % at the power delivery mode and 85.2%, at the backup mode. Test results support the practical value of the method for dual-output wireless charging, benefiting the development of transportation electrification.
