Method and supplying-end module for detecting receiving-end module
First Claim
1. A method of detecting a receiving-end module, for a supplying-end module of an induction type power supply system, the supplying-end module comprising a supplying-end coil, the method comprising:
- detecting a resonant frequency of the supplying-end coil;
determining a coil distance of the receiving-end module and the supplying-end module according to the resonant frequency;
obtaining a maximum resonant voltage and a minimum resonant voltage corresponding to the coil distance; and
determining whether there is a deviation between the supplying-end module and the receiving-end module according to the maximum resonant voltage and the minimum resonant voltage and an input current of the supplying-end coil.
