METHODS, SYSTEMS, AND APPARATUSES FOR HARVESTING WIRELESSENERGYCROSS REFERENCE TO RELATED PATENT APPLICATIONS
[0001] This Application claims priority to U.S. Provisional Application No. 63 / 622,246, filed January 18, 2024, which is hereby incorporated by reference in its entirety.BACKGROUND
[0002] Electric vehicle (EV) deployment has steadily increased in recent years. In 2018, the global stock of electric passenger vehicles exceeded 5 million, and the global EV forecast is for a compound annual growth rate of 29 percent over the next ten years. With EVs expected to secure approximately 32 percent of the total market share for new car sales, EV owners require easy access to a charging infrastructure. Traditional means of charging require EV owners to visit a charging station and connect their vehicle to the charger. One method of charging EVs requires the use of an adapter that couples the EV to a charging station or charging source in order to charge the EV’s battery. However, this method of charging an EV’s battery involving a wired connection requires cables or similar connects that are physically connected to a power supply and may be inconvenient or cumbersome. In addition, wireless methods have been developed for charging the batteries of the EVs. However, conventional wireless charging methods simply rely on induction by generating a current based on the magnetic field created by the electricity flowing through one or more wires. Furthermore, these conventional wireless charging methods require vehicles to remain stationary while being charged.SUMMARY

The vehicle may further include a computing system for determining usage information associated with an amount of energy consumed to charge the battery via the transmission line and location information associated with charging the vehicle via the transmission line.

For example, the current may be generated by the vehicle based on the magnetic field. As an example, the vehicle may comprise an inductive coupling device. The inductive coupling device may generate the current based on the magnetic field produced by the transmission line. For example, the transmission line may comprise a utility power line.

As an example, the vehicle may further comprise a charger or charger assembly comprising a converter. The converter may be configured to convert the current to the first voltage. The first voltage may comprise a first steady state DC voltage. For example, high voltage transmission lines may vary between multiple voltages such as 128 kV, 345 kV, and 765 kV based on the location of the transmission lines. A vehicle harvesting the magnetic field to generate a current would need to be configured to handle multiple inputs based on the multiple voltages. The converter may be configured to receive multiple current inputs and generate a steady state DC voltage.
[0056] At step 540, a second voltage may be generated based on the electrical charge and the first voltage. For example, the vehicle may generate the second voltage based on the electrical charge and the first voltage. The second voltage may comprise a second steady state DC voltage. For example, the vehicle may increase the first voltage to the second voltage based on the electrical charge. As an example, the charger or charger assembly may further comprise a capacitor. Based on the electrical charge generated by the antenna assembly, the capacitor may not provide sufficient capacitance to charge the current generated by the inductive coupling device. The capacitor may be configured to increase the steady state DC voltage (e.g., charge the electrons of the charger assembly to a higher voltage) based on the electrical charge generated by the antenna assembly.
[0057] At step 560, the battery of the vehicle may be charged based on the current and the second voltage. For example, the charger or charger assembly may charge the battery based on the current and the second voltage. In an example, usage information associated with charging the battery may be determined. For example, the charger may be in communication with a computing device of the vehicle. The charger may provide the usage information to the computing device. The computing device may be in further communication with a GPS unit / device. For example, the computing device may receive location information associated with charging the battery via the transmission line. For example, the GPS unit / device may provide location information to the computing device. The computing device may associate location information with the times the vehicle charged the battery via the transmission line. For example, the computing device may determine that the vehicle charged its battery at a first location at a first time point, a second location at a second time point, and a third location at a third time point. The computing device may associate the different locations with each time the vehicle charged its battery. The usage information may comprise the amount of energy consumed to charge the batteryvia the transmission line and the location information associated with charging the battery via the transmission line. The computing device may send the usage information, wherein the usage information (e.g., the amount of energy consumed and the location information) may be used to determine an amount to debit an account of an owner of the vehicle. For example, the computing device may send the usage information to a second computing device (e.g., server, service provider computing device, etc.), wherein the second computing device may determine the amount to debit the account of the owner of the vehicle based on the usage information.
