  • Publication number: 20130038277
    Abstract: The present invention relates to an inductive charging method for vehicles, in which the PS device uses a first frequency converter PS module to detect the PR device. The PS microprocessor can compare ID codes of the PR device and check power receiving status data codes. When finding incorrect power supply, the PS microprocessor will mark it and make other first frequency converter PS modules to cut off power supply through the signal control circuit, and even adjust output power based on power status data codes from the PR device. As total voltage of the PR module is increased by series connection, it is not necessary to use components of high-voltage specifications and water cannot go into sockets, thus preventing electricity leakage. Besides, no wired connection is required and operations concerning identification, stored value or deductions can be carried out.

  • Publication number: 20120314745
    Abstract: The present invention provides a method of time-synchronized data transmission in induction type power supply system, comprising timers and programs installed in a supplying-end module and a receiving-end module to predict the time for generating the trigger signal at the receiving-end end and perform steps for detecting signals to avoid omission. Under the condition of high power transmission, power output on the supplying-end coil is pre-reduced prior to the time expected for receiving trigger data, making the main carrier wave amplitude decrease in a short time period. In every process of data transmission, timers are mutually calibrated and synchronized again to transmit power without detecting and receiving in the period when no data are expected to be transmitted, thus preventing interference of power load noise and enabling the induction type power supply system to transmit data code stably.
