Title:
SYSTEM AND METHOD FOR WIRELESS POWER TRANSFER AND DATA MODULATION FOR VEHICLE
Document Type and Number:
Japanese Patent JP2022117955
Kind Code:
A
Abstract:
To provide a system and a method for wireless power transfer for a vehicle.SOLUTION: A wireless power transfer system can include a transmitter for wirelessly transmitting a HFAC power signal to at least one device of a vehicle such as a sensor (e.g., LiDAR, GPS etc.) and a camera, and a high frequency alternating current (HFAC) inverter electrically coupled to a power source. The HFAC power signal supplies wireless power and a data signal to at least one device of the vehicle. The wireless power transfer system can eliminate a need for a cable and wiring to supply power to the device. Wireless power transfer can include a use of a data modulation circuit and a pulse current source to inject a pulse current to the HFAC power signal as superimposed data. A system configuration can supply power to a plurality of devices. The system can include a plurality of HFAC inverters and transmitters to supply power to multiple sets of devices.SELECTED DRAWING: Figure 1A
