Opto-inductive coupling system and method for wireless charging and data communications

摘要

A wireless recharging system and method in which, by means of direct optical coupling, a matrix of coils and their respective LED lights or lasers interact transmitting and receiving light pulses and wireless power bursts in a fast control loop scheme, allowing precise current control and efficient energy transmission rates with integrated optical data communications in the same interface. An alignment mechanism in which in the matrix of coil transmitters only those receiving direct pulsed light are activated, keeping other coils off, extending the active charging surfaces and improving the overall efficiency, avoiding the requirement of precisely positioning wireless power receptors. A range of power transmission rates and the possibility of recharging different devices with different power requirements simultaneously while laying on top of the charging surface, acting also as an optical communication hub. Charging of vehicles while in motion due to the fast responsiveness of the optical communication.
