Abstract

A method for charging a battery of a vehicle with electrical energy using a charging station which includes at least one source for generating flashes. At least one flash is generated using the at least one source, an amount of electrical energy is provided via the air using the at least one receiver of the vehicle. The received amount of electrical energy is provided to the battery by the at least one receiver.

First claim

The invention claimed is:

1. A method for charging a battery of a vehicle with electrical energy using a charging station, the charging station includes at least one source for generating electrical flashes, wherein at least one flash is generated using the at least one source, using which an amount of electrical energy is provided via the air to at least one receiver of the vehicle, wherein the received amount of electrical energy is provided to the battery by the at least one receiver, wherein an amount of electrical energy is requested at the charging station at an agreement time by the vehicle located at an agreement location, communicating how much electrical energy is required by the battery, wherein a charging time is agreed, at which the receiver of the vehicle will have at most a target distance to the source at a charging location, wherein as soon as the vehicle reaches the charging location at the charging time and the receiver has at most the target distance to the source, the at least one flash having the amount of electrical energy is generated by the source, is transported to the receiver via the air, and is received by the receiver.

2. The method as claimed in claim 1 , wherein charging occurs when the vehicle passes the at least one source, wherein the at least one receiver has at most the target distance to the at least one source.

3. The method as claimed in claim 2 , wherein the charging station is provided an item of information about the amount of electrical energy to be provided from the vehicle via a communication connection before generating the at least one flash.

4. The method as claimed in claim 1 , wherein the charging station is provided an item of information about the amount of electrical energy to be provided to the vehicle via a communication connection before generating the at least one flash.

5. A system for charging a battery of a vehicle with electrical energy, which includes a charging station, which includes at least one source for generating electrical flashes, wherein the at least one source is designed to generate at least one flash, which provides an amount of electrical energy via the air to at least one receiver of the vehicle, wherein the at least one receiver is designed to provide the received amount of electrical energy to the battery, characterized in that an amount of electrical energy is requested at the charging station at an agreement time by the vehicle located at an agreement location, wherein the vehicle communicates how much electrical energy is required by the battery, wherein a charging time is agreed, at which the receiver of the vehicle will have at most a target distance to the source at a charging location, wherein as soon as the vehicle reaches the charging location at the charging time and the receiver has at most the target distance to the source, the at least one flash having the amount of electrical energy is generated by the source, is transported to the receiver via the air, and is received by the receiver.

6. The system as claimed in claim 5 , in which the at least one source is designed as a Tesla coil.

7. The system as claimed in claim 6 , wherein the at least one receiver is arranged on an outer wall of the vehicle and is designed as an antenna, lightning conductor, and/or part of a vehicle body of the vehicle.

8. The system as claimed in claim 6 wherein at least one transformer is arranged in the vehicle and is designed to transform a value of at least one electrical parameter of the amount of electrical energy received via the flash and to provide it to the battery.

9. The system as claimed in claim 6 , wherein a communication module is associated with the charging station, and a further communication module is arranged in the vehicle.

10. The system as claimed in claim 6 , wherein the at least one source of the charging station is arranged adjacent to and/or above a roadway for the vehicle.

11. The system as claimed in claim 5 , wherein the at least one receiver is arranged on an outer wall of the vehicle and is designed as an antenna, lightning conductor, and/or part of a vehicle body of the vehicle.

12. The system as claimed in claim 11 , wherein at least one transformer is arranged in the vehicle and is designed to transform a value of at least one electrical parameter of the amount of electrical energy received via the flash and to provide it to the battery.

13. The system as claimed in claim 11 , wherein a communication module is associated with the charging station, and a further communication module is arranged in the vehicle.

14. The system as claimed in claim 11 , wherein the at least one source of the charging station is arranged adjacent to and/or above a roadway for the vehicle.

15. The system as claimed in claim 5 , wherein at least one transformer is arranged in the vehicle and is designed to transform a value of at least one electrical parameter of the amount of electrical energy received via the flash and to provide it to the battery.

16. The system as claimed in claim 15 , wherein a communication module is associated with the charging station, and a further communication module is arranged in the vehicle.

17. The system as claimed in claim 15 , wherein the at least one source of the charging station is arranged adjacent to and/or above a roadway for the vehicle.

18. The system as claimed in claim 5 , wherein a communication module is associated with the charging station, and a further communication module is arranged in the vehicle.

19. The system as claimed in claim 18 , wherein the at least one source of the charging station is arranged adjacent to and/or above a roadway for the vehicle.

20. The system as claimed in claim 5 , wherein the at least one source of the charging station is arranged adjacent to and/or above a roadway for the vehicle.
