The method according to claim 15, wherein one item of the at least one item of information is a maximum noise limit value, and wherein the maximum noise limit value is indicative of the maximum noise emissions that the motor vehicle or the at least one electrical energy storage device are allowed to emit during the charging.

18. The method according to claim 17, wherein one item of the at least one item of information is an identification number of the charging point, and wherein the maximum noise limit value is determined using the identification number.

19. The method according to claim 18, wherein the maximum noise limit value is determined in the motor vehicle.

20. The method according to claim 18, wherein the motor vehicle receives the maximum noise limit value from a server.

21. A method for charging at least one electrical energy storage device of a motor vehicle, the method comprising: specifying at least one maximum charging limit parameter corresponding to maximum noise emissions to the motor vehicle for the charging; and using a specification to limit the maximum noise emissions that the motor vehicle or the at least one electrical energy storage device are allowed to emit during the charging.

22. The method according to claim 21, wherein the at least one maximum charging limit parameter is a maximum charging power or a maximum charging current.

23. The method according to claim 21, wherein the at least one maximum charging limit parameter is determined taking into consideration a motor vehicle type or a motor vehicle class of the motor vehicle.

24. The method according to claim 21, wherein the maximum noise emissions are limited using at least one of a day of a week, a time of the day, or a date on which the motor vehicle is charged.

25. The method according to claim 21, further comprising: acquiring at least one surroundings value, wherein: the at least one surroundings value is indicative of noise emissions present in the surroundings, and the at least one surroundings value is used to limit the maximum noise emissions.

26. A method for charging multiple motor vehicles at multiple charging points, the method comprising: in each of the motor vehicles, limiting the maximum noise emissions that the motor vehicles are allowed to emit during the charging using the method according to claim 15, wherein at least one of maximum noise limit values or charging limit parameters are selected such that noise emissions jointly emitted by the multiple motor vehicles, or noise emissions jointly emitted by the multiple motor vehicles and the multiple charging points do not exceed a limit value for surroundings noise emissions.

27. A motor vehicle comprising: at least one energy storage device, wherein the motor vehicle configured to carry out the method according to claim 15.

28. A motor vehicle comprising: at least one energy storage device, wherein the motor vehicle is configured: to acquire at least one item of information from a charging point, and to limit maximum noise emissions that the motor vehicle or the at least one energy storage device are allowed to emit during a charging process using the at least one item of information; and wherein the at least one item of information: is a maximum noise limit value, wherein the maximum noise limit value is indicative of the maximum noise emissions that the motor vehicle of the at least one energy storage device are allowed to emit during the charging process; or is an identification number of the charging point, wherein the maximum noise limit value is determined using the identification number.

29. A computer product comprising a non-transitory computer readable medium having stored thereon program instructions that, when executed by a processor, carries out the method according to claim 15.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0071] FIG. 1 shows a method according to an exemplary embodiment of the invention.

DETAILED DESCRIPTION OF THE DRAWING

[0072] The technology disclosed here is now explained with reference to FIG. 1. In step S100, the method is started. In step S200, the motor vehicle acquires the identification number of the charging point. This may be achieved for example through wired communication. Based on the identification number, the motor vehicle may then determine the maximum noise limit value in step S300, for example by receiving the noise limit value corresponding to this identification number through a server query. Provision may likewise be made for the motor vehicle to receive multiple noise limit values that are linked to this identification number. By way of example, various noise limit values for various times of day may be transmitted. Based on the one or more received noise limit values, in step S400, the maximum noise emissions that the motor vehicle or the electrical energy storage device emit are limited. Provision may be made for the steps to be repeated during charging.

[0073] For the sake of legibility, the expression “at least one” has been omitted in some cases by way of simplification. If a feature of the technology disclosed here is described as being singular or undefined, then a plurality thereof is intended to be jointly disclosed at the same time.

[0074] The above description of the present invention serves only for illustrative purposes and not for the purposes of restricting the invention. Various changes and modifications are possible within the scope of the invention without departing from the scope of the invention and its equivalents.
