1. An inductive charging system for vehicles, comprising:
a power receiving (PR) device, disposed in a vehicle and comprising:
a signal control circuit; anda plurality of first frequency converter power sourcing (PS) sub-modules, wherein each of the plurality of first frequency converter PS sub-modules comprises a PS microprocessor coupled to the signal control circuit; and a PS device, disposed in a charging equipment separated from the vehicle and comprising a first PR sub-module; wherein the inductive charging system for vehicles performs an inductive charging method, and the inductive charging method comprises:
(A01) the PS device standby, switch off power output from the first frequency converter PS sub-modules and eliminate system status markings in the PS microprocessor;(A02) the PS device detects if there is any PR device in an induction range by using the first frequency converter PS sub-module that corresponds to the first PR sub-module of the PR device; proceed to step (A03) if a startup code is received from the PR device; otherwise, proceed to step (A01);(A03) the PS microprocessor of the first frequency converter PS sub-module corresponding to the first PR sub-module checks an ID code of the PR device and decides if it is on a list of authorized power receivers; if yes, proceed to step (A04); otherwise, proceed to step (A08);(A04) the PS microprocessor of the first frequency converter PS sub-module corresponding to the first PR sub-module decides if the PR device is in a state of normal power supply by checking its power receiving status data code; if yes, proceed to step (A07); otherwise, proceed to step (A05);(A05) mark system status of the PR device as incorrect in the PS microprocessor of the first frequency converter PS sub-module corresponding to the first PR sub-module;(A06) deliver the incorrect system status in the PS microprocessor of the first frequency converter PS sub-module via the signal control circuit to the PS microprocessors of other first frequency converter PS sub-modules for handling;(A07) check other system status markings delivered by the signal control circuit in the PS microprocessors of other first frequency converter PS sub-modules and decide if other first frequency converter PS sub-modules supply power normally; if yes, proceed to step (A09); otherwise, proceed to step (A08);(A08) cut off power output from the first frequency converter PS sub-modules and proceed to step (A01);(A09) the PS microprocessors of the first frequency converter PS sub-modules check the power currently received by using power status data codes from the PR device and compare it with a preset power; if the currently received power is larger than the preset power, proceed to step (A10); if the currently received power is smaller than the preset power, proceed to step (A11); if it equals the preset power, proceed step (A12);(A10) increase working frequency of output that should be adjusted from the corresponding PS microprocessor to the PS driving unit to reduce output frequency through frequency conversion, and then proceed to step (A12);(A11) reduce the working frequency of the output that should be adjusted from the corresponding PS microprocessor to the PS driving unit to increase the output frequency through frequency conversion;(A12) the PS microprocessors check if output power of the corresponding first frequency converter PS sub-modules has reached a preset upper limit; if yes, proceed to step (A13); otherwise, proceed to step (A14);(A13) the PS microprocessors of other first frequency converter PS sub-modules mark the system status of the PS device as incorrect if the output power has reached the preset upper limit, and then proceed to step (A06);(A14) the PS microprocessors continue to supply electricity and proceed to step (A03). |
