Abstract

A battery pack includes an electrical energy store, a data memory and an interface for the alternative connection of the battery pack to a data source or a data sink. The data memory is designed to receive data from the data source while the interface is connected to the data source, and to supply the data in the data memory to the data sink while the interface is connected to the data sink.

Claims

1. A battery pack, comprising:

an electrical energy store;

a data memory; and

an interface for selective alternative connection of the battery pack to one of a data source or a data sink;

wherein the data memory is configured to (i) store data from the data source while the interface is connected to the data source, and (ii) provide the data from the data memory to the data sink while the interface is connected to the data sink.

2. The battery pack as recited in claim 1, wherein the data memory includes a protected memory to hold identifying information.

3. The battery pack as recited in claim 1, wherein data are transmitted between an electrical machine and a central control unit, the electrical machine including one of the data source and the data sink, and the central control unit including the other one of the data source and the data sink.

4. A method for transmitting data from a data source, which is part of one of an electrical machine or a central control unit, to a data sink which is part of the other one of the electrical machine or the central control unit, the method comprising:

transmitting data from the data source to a data memory of a battery pack while the battery pack is connected to the data source; and

transmitting data from the data memory to the data sink while the battery pack is connected to the data sink.

5. The method as recited in claim 4, further comprising:

transmitting identifying information between the battery pack and one of the data source or the data sink, data being transmitted one of into or out of the data memory only if the transmitted identifying information indicates a permitted information partner.

6. The method as recited in one claim 5, wherein usage information of the electrical machine is transmitted to the central control unit with the aid of the battery pack, and wherein usage comments are transmitted, in response to the usage information, from the central control unit to the electrical machine with the aid of the battery pack.

7. The method as recited in claim 6, wherein the response is based on multiple items of usage information from different electrical machines.

8. The method as recited in claim 6, wherein a function of one of the battery pack or the electrical machine is deactivated in response to the usage information if, on the basis of the usage information, the one of the battery pack or the electrical machine is determined to have been previously used without authorization.

9. The method as recited in claim 6, wherein additional information is compiled in the battery pack, and the compiled additional information data are appended to the data transmitted to the data sink.

10. A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for transmitting data from a data source, which is part of one of an electrical machine or a central control unit, to a data sink which is part of the other one of the electrical machine or the central control unit, the method comprising:

transmitting data from the data source to a data memory of a battery pack while the battery pack is connected to the data source; and

transmitting data from the data memory to the data sink while the battery pack is connected to the data sink.
