1) Design a new configuration of energy-encrypted wireless power transfer (WPT) system for roadway-powered electric vehicles (EVs), which can selectively charge the authorized EVs while preventing the unauthorized EVs from stealing the energy; 2) Develop a novel energy encryption scheme for WPT, which can offer high security and high feasibility while maintaining efficient and effective power transfer; 3) Formulate new analytical models of the proposed system, with emphasis on power transfer efficiency and power delivery as well as steady-state and frequency responses; 4) Perform electromagnetic field analysis and dynamic simulation of the whole system to optimize the system parameters, and to assess the encryption performance, safety issue and electromagnetic compatibility; 5) Develop new control strategies of the proposed system to achieve energy encryption while optimizing the power transfer efficiency and power delivery; 6) Implement the whole system for experimentation, hence evaluating its technical performances and cost-effectiveness.
