Abstract:
      To solve the problems of inconvenient charging and short mileage in the development of electric vehicles(EVs), the research on dynamic wireless power transfer(DWPT) on the basis of wireless power transfer(WPT) has attracted more and more attention. The construction of a timely, high speed and stable data communication network is important for the coordinated control of EV and power source in a sectional DWPT system, the real-time sharing of battery's state of charge and locations of EVs, and the assurance that the power source can switch timely thus the system can provide an orderly and efficient power supply. In this paper, the requirements of communication network in the sectional DWPT system, and the relationship between the primary layout and the communication network frame, were introduced. The network communication architecture in an example system was built through the primary CAN bus communication and the wireless communication module nRF24L01 configured by SPI interface; meanwhile, the proposed communication network was experimentally verified on the constructed small-power DWPT demonstration platform.
