Description

BACKGROUND OF THE INVENTIONThe invention relates to a service station having a housing and a control. The interior of the housing has a first compartment, wherein the first compartment has a closable cover or flap / door. A standardized electrical connection interface, in particular a socket, is arranged in the first compartment. A user with access to the interior of the first compartment, for example by means of a key, code or an access card, can use the connection interface in order to charge an accumulator, for example an accumulator of his e-bike.The problem with known service stations is their erection inside buildings, since their use can pose an increased risk of fire.Object of the InventionIt is therefore an object of the invention to further develop a service station such that it can also be used in the interior of a building.DESCRIPTION OF THE INVENTIONThis object is achieved according to the invention by a service station according to claim 1.The object is thus achieved according to the invention by a service station described at the beginning, which has a plurality of fire protection devices for the first compartment, which fire protection devices differ from one another. This creates redundant fire safety, which makes it possible to erect and operate the service station also in the interior of a building.The terms ", "under", "ceiling", etc., refer to the assembled state of the service station.A fire protection device can be designed in the form of a voltage disconnection of the connection interface. A control provided for this purpose can be designed to switch off the voltage whena voltage output from the port exceeds a predetermined value;a current output by the connection interface exceeds a fixed value; and / orthe temperature measured in the interior of the first compartment exceeds a defined value, wherein the temperature is measurable by a temperature sensor of the service station. The temperature sensor is preferably arranged in the first compartment.In a particularly preferred embodiment of the invention, a fire protection device is designed in the form of an extinguishing device. The extinguishing device has an extinguishing material which can be released in the event of a fire.The extinguishing material can be present in particular in the form of a gas, a powder and / or a liquid. The extinguishing material is preferably in the form of a mineral wool, in particular a glass wool or a rock wool, in the form of vermiculite, hollow glass granules, in particular nitrogen-filled hollow glass granules, and / or expandable graphite.The extinguishing material can be released by means of the controller. The controller can be connected to a sensor, in particular a smoke and / or temperature sensor, preferably the temperature sensor described above, in order to detect a fire. The fire protection device can have a / e spray device, pump and / or valve controllable by the controller in order to release the extinguishing material into the interior of the first compartment.Preferably, however, the extinguishing material is releasable without an electrical control. For example, a film can be arranged in the ceiling of the first compartment, on which film or behind the extinguishing material is arranged. If, in the event of a fire, the film melts, softens and / or tears, the extinguishing material is released into the interior of the first compartment under the load and / or the pressure of the extinguishing material.Generally, a gaseous extinguishing material, e.g. carbon dioxide or nitrogen, may be present in a compartment connected to the interior of the first compartment, which compartment is separated from the interior by a film. If the film melts due to a fire, the gaseous extinguishing material flows into the interior and can extinguish the fire.The film can comprise polyethylene (PE), in particular low-density polyethylene (LDPE), for example according to the B1 certification according to DIN 4102. The film preferably has no fire protection, so that it quickly releases the extinguishing material in the event of a temperature increase. The film's fire load is typically in the gram range and is negligible for many applications.The foil is preferably arranged on a grid, in particular a metal grid. If the film melts in the event of a fire, the film remains at least partially on the grid and the extinguishing material, in particular in liquid or solid form, falls or flows onto the fire in the interior of the first compartment.The connection interface is preferably designed in the form of a household socket or a USB interface, so that a large number of conventional batteries can be charged.In the first compartment, a plurality of connection interfaces of the service station, which can be switched off in particular by the controller, can be arranged. The connection interfaces can be constructed identically or-preferably-differently.The service station may include a second compartment. Preferably, the service station has a further compartment or a plurality of further compartments.The service station can each have a plurality of different fire protection devices for different compartments, which are designed in particular as described above.The object according to the invention is furthermore achieved by a method for preventing or extinguishing a fire in a service station described here, having the following method steps, at least two of which are carried out: A) detection of a voltage by a controller which exceeds a predefined voltage and switching off the connection interface by the controller; B) detection of a current by a controller which exceeds a predefined current and switching off the connection interface by the controller; C) detection of a temperature by a temperature sensor connected to a controller which exceeds a predefined temperature and switching off the connection interface by the controller; D) release of an extinguishing material after detection of smoke by a smoke sensor and / or from an elevated temperature by a temperature sensor and / or by at least partial destruction of a part of a fire protection device which retains the extinguishing material.Before, after or between method steps A) to D), a further method step or further method steps can be carried out.Further advantages of the invention will become apparent from the description and the drawing. Likewise, the features mentioned above and those set out further below can be used according to the invention individually or together in any desired combinations. The embodiments shown and described are not to be understood as a final enumeration, but rather have exemplary character for describing the invention.DETAILED DESCRIPTION OF THE INVENTION AND DRAWINGFig. 1 shows a schematic perspective view of a part of a service station according to the invention.

The service station 10 can be configured to switch off exclusively for the connection point 20 or for a plurality of connection points, in particular for all connection points, of the service station 10.In the present case, a fourth fire protection device 22 d, which functions in particular independently of the connection point 20 and / or controller 24, is additionally provided in the service station 10. The fourth fire protection device 22 dcomprises a film 28 on which an extinguishing material 30 is arranged. The film 28 is preferably arranged on a grid 32. The grid 32 may represent a ceiling 34 of the interior 16.The film 28 may be in the form of a film that melts at temperatures of less than 200° C. The film 28 can be formed, for example, from polyethylene (PE), in particular low-density polyethylene (LDPE). If the temperature in the interior 16 exceeds the melting temperature of the film 28, the film 28 melts and the extinguishing material 30 falls into the interior 16. the fourth fire protection device 22 dmay be provided exclusively for the first compartment 14 aor for a plurality of compartments (e.g. 14 a, 14 b), in particular all compartments (e.g. 14 a, 14 b), of the service station 10.
