An inductive charging method for vehicles includes a power sourcing (PS) device using a first frequency converter PS sub-module to detect a power receiving (PR) device. The PS microprocessor can compare ID codes of the PR device and check power receiving status data codes. When finding an incorrect power supply, the PS microprocessor will mark it and make other first frequency converter PS sub-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.
