2. The control module according to claim 1, characterised in that, the control unit comprises a switch, which is arranged between the supply terminal and the energy store, wherein the control module is configured, when a connection is produced between the control module and the delimiting device, to connect the supply terminal to the energy store by closing the switch, and, when the connection is cancelled, to separate the supply terminal from the energy store by opening the switch.

3. The control module according to claim 2, characterised in that the switch comprises a mechanical switch, in particular a relay.

4. The control module according to claim 2, characterised in that the switch comprises a semiconductor switch, which is configured with at least one bipolar transistor, a field-effect transistor or an insulated gate bipolar transistor.

5. The control module according to claim 4, characterised in that the switch is configured as a unidirectional switch.

6. The control module according to claim 1, characterised in that the energy store comprises a chemical energy store, in particular a lead battery or an NiMH battery, or a capacitor module.

7. The control module according to claim 1, characterised in that the control module comprises an automatic actuation apparatus, wherein an actuation occurs upon connection of the control module to the delimiting device, and the control unit is configured, upon actuation of the actuation apparatus, to perform a rapid charging and/or a rapid discharging of the energy store.

8. The control module according to claim 7, characterised in that the actuation apparatus comprises a mechanical actuation element, which is configured in such a way that it is mechanically actuated by the connection of the control module to the delimiting device.

9. The control module according to claim 7, characterised in that the actuation apparatus comprises an electric actuation element, which is configured in such a way that it is electrically actuated by the connection of the control module to the delimiting device.

10. The control module according to claim 7, characterised in that the actuation apparatus comprises a data interface and is configured to receive from a corresponding interface of the delimiting device a signal via the interface when the control module is connected to the delimiting device.

11. The control module according to claim 1, characterised in that the control unit is configured to prevent a deep discharge of the energy store.
