Description

[0001] The invention relates to a storage facility for a vehicle and / or a battery, in particular a vehicle with an electric drive motor. Furthermore, the invention relates to an arrangement or quarantine area for storing, securing, examining, and dismantling a vehicle and / or a battery, in particular a vehicle with an electric drive motor, which includes a suitable storage facility. The storage facility has a roof, a floor, side walls, and a door opening, closable by a door element, for loading and unloading the vehicle. The roof, floor, side walls, and, when closed, the door element, enclose a storage compartment that is at least liquid-tight, and at least one controllable fluid inlet is provided through which, upon the occurrence of a definable event, in particular the formation of smoke, sparks, and / or flames, at least one fluid can be selectively introduced into the storage compartment as an extinguishing agent.

[0002] The proportion of motor vehicles on the road equipped with an electric motor, either as a purely electric drive or as part of a hybrid drive, is steadily increasing. It is important to consider that the use of electric vehicles presents unique and previously unforeseen requirements regarding procedures for handling traffic accidents to ensure the safety of people and the environment. These new challenges generally stem from the use of battery cells in the vehicles, which require special handling and procedures in the event of an accident or other incident. Current manufacturer specifications from major vehicle manufacturers stipulate that, following an accident and if the airbags have deployed, the entire battery unit must be removed and visually inspected.

[0003] Furthermore, there is always a risk that parts of the power supply, especially the battery boxes, may have been deformed in a traffic accident, so that the risk of short circuits and consequently a vehicle fire persists even some time after the actual accident. This risk therefore also exists for a parked vehicle, regardless of whether the vehicle was actively or passively involved in an accident, for example, as a vehicle parked at the roadside.

[0004] For the aforementioned reasons, vehicle manufacturers require their dealers to provide so-called quarantine areas where vehicles involved in accidents or otherwise damaged can be parked. According to regulations in Germany, a quarantine area of ​​218.75 m² is required. Since vehicle manufacturers require each dealer to provide two of these quarantine areas, this means that dealers, particularly vehicle repair shops, must provide an area of ​​almost 440 m² for such quarantine facilities. Especially in city centers, this often represents a comparatively high financial burden for dealers.

[0005] Furthermore, it should be noted that the respective quarantine areas must also comply with the applicable regulations regarding environmental and fire safety. According to current recommendations or regulations, it should be guaranteed that the areas are not visible to customers, are easily accessible for emergency vehicles, have a barrier separating them from adjacent areas, offer protection from moisture, especially rain, have a paved surface, and comply with the applicable water law regulations.

[0006] Besides parking and storing damaged electric vehicles, transporting such vehicles from the accident site also requires a high level of safety precautions. Ultimately, the possibility of a vehicle catching fire during transport from the accident site to the quarantine area must also be considered.

[0007] The general problem is that electric vehicles involved in an accident can catch fire at the accident site, during transport, or even after they have been parked, particularly in a quarantine area. Therefore, it is essential to be able to continuously monitor an electric vehicle involved in an accident throughout all of the aforementioned periods and to extinguish any fire quickly and efficiently in order to minimize the risk of danger to people, property, and the environment.

[0008] In this context, EP 3 744 406 A1 discloses a special recovery device for vehicles with electric drive and batteries as energy storage. The described recovery device has a lockable container that can be filled with extinguishing water to hold a vehicle. One end of the container is designed as a watertight door. Furthermore, the container has a winch to pull a vehicle into the interior with the door open and a movable lid that can be used to securely close the top of the container when necessary. Documents EP 3 778 430 A1 and DE 10 2017 010960 A1 also disclose recovery devices for vehicles with electric drive and batteries as energy storage according to the prior art.

[0009] Using the described recovery device, it is possible to pull a wrecked vehicle, especially a burning electric vehicle, into the open container using the winch, close the container door, and then flood the interior with extinguishing water. Since special additives are often mixed into the extinguishing water, after flooding, the container's top opening can be closed with the movable lid, and the container, filled with the vehicle and extinguishing water, can be transported from the accident site. However, a problem with the described recovery device is that neither monitoring a vehicle parked inside the container nor extinguishing a fire while it is in motion is possible. Rather, the presence of personnel is always required to detect the outbreak of a fire, close the container, and flood the interior with extinguishing water.

[0010] Considering the solutions known from the prior art for parking, storing, and transporting electric vehicles, the lack of preventative fire protection measures is a significant disadvantage. In particular, these solutions do not allow for a rapid and effective response to a developing fire. A recurring problem is that electric vehicles can ignite long after an accident, sometimes even up to 48 hours later, due to a battery short circuit and the associated sparks and heat generation.

[0011] Based on the prior art's known technical solutions and the problems described above, the invention aims to provide a depot and an arrangement that allows a wrecked electric vehicle to be safely parked, stored, transported, inspected, and dismantled without endangering nearby people, objects, or the environment in the event of a fire. The area in which the vehicle is stored or parked should be relatively small compared to known quarantine areas, thus offering advantages in terms of space requirements.Furthermore, the specified device should be designed with preventative fire protection in mind, ensuring that an electric vehicle involved in an accident can be parked safely and isolated from its surroundings, and that any fire hazards are quickly detectable. In the event of a fire, the fire in the vehicle parked in the depot should be extinguished as quickly and effectively as possible, minimizing risks to people, animals, and plants in the vicinity of the depot, as well as to the environment, particularly due to smoke development and / or the extinguishing agent used. In this context, fires should be detected as quickly as possible without requiring human intervention, and appropriate measures should be taken to extinguish or smother the fire.Furthermore, the requirements arising from applicable fire safety and emissions control regulations, as well as water protection regulations, should be able to be addressed in a comparatively simple manner. The proposed technical solution should also be characterized by a relatively simple design, reliability even under varying conditions, and ease of use, preferably with a high degree of automation.

[0012] Furthermore, preferably on an enclosed site, a vehicle should not only be able to be safely parked and stored, but preferably also inspected and dismantled using the arrangement according to the invention.

[0013] The problem described above is solved by a depot according to claim 1 and an arrangement according to claim 14. Advantageous embodiments of the invention are the subject of the dependent claims and are explained in more detail in the following description with partial reference to the figures.

[0014] The invention relates initially to a depot according to claim 1. A key feature of the solution according to the invention is that a vehicle is stored in the enclosed interior of the depot and, upon the occurrence of a definable event, in particular the generation of smoke, sparks, flames, and / or a specific gas, a targeted extinguishing and / or smothering process can be initiated without the extinguishing fluid introduced into the depot unintentionally escaping from the interior. With the aid of a depot designed according to the invention, preventive fire protection can thus be implemented in a special way for electrically powered vehicles involved in accidents, where the risk of ignition persists even for a considerable time after an accident. Likewise, in the event of a vehicle explosion, it can be prevented that vehicle parts escape into the surrounding area and cause a hazard.

[0015] In general, it is conceivable that the depot is a container with six boundary walls, at least one of which has a suitable door element or is designed as a door element, such as a swing or folding gate. It is also conceivable that the depot is designed in the form of a garage, in which the side walls, the roof, and the wall with the door element are attached to a suitable base, for example, a foundation slab, in such a way that no extinguishing fluid can unintentionally escape from the interior of the depot when it is closed.

[0016] In any case, at least one sealing element is provided between the movable door element and the adjacent storage area, which, when the door element is closed, ensures a fluid-tight seal between the interior and the environment. Depending on the extinguishing fluid used—that is, whether it is a liquid, foam, and / or a gas, particularly carbon dioxide—the seal is designed to be gas-tight and / or liquid-tight.

[0017] In a specific embodiment of the invention, the fluid inlet and a fluid supply connected to it are therefore designed in such a way that water with or without additives and / or a gas, in particular carbon dioxide, can be introduced into the depot interior as an extinguishing fluid, in particular to extinguish or smother developing or occurring flames.

[0018] Preferably, the side walls are connected to a depot floor on their respective sides opposite the roof in such a way that the side walls, the roof, and the depot floor form a self-supporting unit, which has a door opening on at least one side that can be closed by at least one door element. Preferably, the depot is designed in the form of a container or a swap body, which has a door or hatch in the area of ​​at least one side wall, so that when the door is open, a vehicle, in particular a vehicle with an electric drive, can be brought into the depot interior.

[0019] In a particular embodiment, the depot has at least one lifting eye, a gripping edge, a pin receptacle, a roller, and / or a movable or fixed support leg on at least one outer surface. Such a depot, designed as a container, offers the advantage of being suitable for both stationary storage of a vehicle and its transport, for example, from the accident site to a parking area. At the accident site, such a depot is loaded with the vehicle involved in the accident, transferred with the vehicle inside onto a transport or towing vehicle, secured in a transport position, and unloaded at the designated parking area. The vehicle used to transport such a depot can be a self-propelled vehicle, a trailer, or a semi-trailer.In a special way, it is conceivable that the depot is designed as a skip or roll-off container that can be picked up and transported by a suitable vehicle.

[0020] The depot designed according to the invention for storing a wrecked vehicle or a vehicle damaged in any other way enables early, automated detection of a vehicle fire, thus serving preventive fire protection and ensuring that if a fire starts inside the depot, it cannot spread to the surroundings and can be extinguished quickly without endangering the environment. At the same time, the depot allows for comparatively space-saving, secure, and concealed storage of electrically powered vehicles involved in an accident and requiring appropriate monitoring.

[0021] In a particular embodiment of the invention, the fluid supply is designed such that a gas, foam, and / or water, with or without additives, can be selectively introduced into the interior of the depot through the fluid inlet, which can be closed by an actuating element. The fluid inlet can have at least one sprinkler nozzle and / or a movable jet nozzle. The nozzles are preferably arranged on the side walls, the roof, and / or the floor in such a way that individual or multiple points or areas of the depot interior can be selectively treated with extinguishing fluid.

[0022] In this context, it is conceivable that the fluid supply itself can be connected to an external gas or water supply and / or has at least a liquid tank or pressurized gas storage tank in which the extinguishing fluid required for extinguishing operations is stored and, in the event of an alarm—i.e., upon detection of smoke, flames, sparks, gas, and / or increased heat generation—is automatically introduced into the depot interior through the fluid inlet when the actuator is open. It is particularly advantageous if the fluid supply has at least one tank and / or pressurized gas storage tank mounted on the roof and / or a side wall of the depot. Alternatively or additionally, it is conceivable that a tank with the required filling volume is located next to the depot and connected to the fluid supply via suitable fluid lines.

[0023] Preferably, the fluid supply system also includes means for pumping a fire extinguishing fluid, such as at least one pump and / or fan, which, together with the necessary supply lines (pipes and / or hoses), is mounted directly on the roof and / or on at least one wall of the depot. This creates a particularly compact unit that enables the safe storage of damaged electric vehicles and prevents extensive fire damage.

[0024] In a specific embodiment of the depot according to the invention, the fluid supply includes at least one heat exchanger and / or one fluid filter, making it generally possible to circulate extinguishing fluid used to extinguish a vehicle fire through the fluid inlet into the depot interior, discharge it through a fluid outlet, and, after appropriate material and / or thermal treatment, return it to the fluid inlet. Alternatively or additionally, it is conceivable that if smoke, sparks, fire, flames, and / or gas development initiating an extinguishing process is detected by the sensor unit in the depot interior, the depot interior is filled or flooded with the extinguishing fluid, at least to the extent that the vehicle located in the depot interior, preferably only the source of the fire, is completely covered by fluid and / or oxygen is displaced from this area.In a very special embodiment, the sensor system inside the depot is therefore designed in such a way that the amount of extinguishing fluid introduced into the depot interior is limited to the amount required to extinguish or smother the fire.

[0025] According to another embodiment, the roof, the floor, the door element and / or the side walls have at least partially a fire-retardant material and / or are provided with a fire-retardant coating, in particular on the side facing the interior of the depot.

[0026] Furthermore, it is advantageous if at least one of the aforementioned walls and / or the door element is equipped with a thermal insulation element, so that in the event of a fire inside the depot, the resulting heat is not directly conducted to an outer shell of the depot, thus preventing the risk of burns to people or animals touching the depot from the outside. In a further development, a platform suitable for receiving a vehicle is provided inside the depot, which is movable relative to the door opening, at least when the door element is open. Such a platform makes it possible to move it out of the depot, place a vehicle on the platform, and then move the platform and the vehicle back into the depot.Preferably, rollers, rails, and / or hinges are provided on the platform and / or the depot to allow the platform to be moved appropriately, with or without a vehicle parked on it, relative to the door opening. Regardless of whether a platform is provided, it is advantageous if the depot includes a ramp element, for example, in the area of ​​the door opening, over which a vehicle can be rolled relatively easily into the depot interior. Ideally, at least one ramp element in the area of ​​the door opening is attached to the depot via a hinge or joint and can be folded up or down or pivoted as needed.

[0027] Furthermore, a specific embodiment of the invention provides that at least one cable of a manually and / or motor-driven winch is arranged inside the depot. Such a winch, which is preferably operable from the outside and particularly preferably remotely controlled, enables the easy insertion of a vehicle into the depot. Preferably, the cable drum with a drive motor is located, preferably encapsulated, inside the depot, optionally with or without a power supply, while the control of the motor and thus of the drum connected to the motor for winding and unwinding the cable is implemented remotely via a wireless connection.

[0028] According to the invention, it is provided that the at least one sensor unit for detecting smoke, gas, flame and / or spark formation and / or the data evaluation unit each have at least one interface for wireless data transmission, so that these two units can preferably exchange data unidirectionally or bidirectionally.

[0029] Furthermore, according to the invention, the data evaluation unit and a data storage device are designed for unidirectional or bidirectional data transmission, and the data evaluation unit is coupled to the data storage device, in which preferably vehicle-specific data is stored. The stored data optionally includes data relating to the type and design of a vehicle's drive unit, its dimensions, in particular external dimensions, as well as the type, design, and spatial location of potential fire sources, especially energy storage devices such as batteries. In principle, it is conceivable that a data storage device containing the corresponding data is arranged in the immediate vicinity of the depot or in a central data storage unit or a central server.It is particularly advantageous if the data evaluation unit and the data storage unit each have an interface for wireless data transmission, via which the two units can exchange data, preferably encrypted.

[0030] In general, it is conceivable to design a depot according to the invention in different sizes, i.e., to accommodate passenger cars as well as trucks or commercial vehicles. It is particularly advantageous in this context if the depot has at least one adjustable element, so that the size of the depot, especially the interior space, can be changed as needed, for example by extending at least one side wall.

[0031] According to a further embodiment of the invention, a fluid discharge system with a fluid outlet is provided for conveying the fluid introduced into or located within the depot interior from the depot interior into the surrounding environment. Preferably, the fluid discharge system is at least indirectly connected to a pipeline of a wastewater system. Preferably, the fluid discharge system also has at least one pump that enables automated and / or demand-based pumping of extinguishing fluid from the depot. Depending on the extinguishing fluid used and the applicable regulations, it is also conceivable in this context that the fluid discharge system, either within or outside the depot interior, preferably attached to at least one depot wall, includes a filter element that enables at least partial filtration and / or even thermal or chemical treatment of the fluid conveyed from the depot interior.

[0032] Furthermore, a flue gas discharge system is advantageously provided, through which a flow channel can be established, at least temporarily, between the interior of the depot and its surroundings for the removal of gases or vapors generated within the depot. Such a flue gas discharge system advantageously allows smoke, vapor, and / or gas generated within the depot to be removed, with at least one filter element preferably being arranged in the flue gas discharge system to prevent harmful or environmentally hazardous gases or particles from entering the depot's surroundings. The design of the flue gas discharge system is adapted to the regulations applicable at the installation site of a depot constructed according to the invention.

[0033] Furthermore, it is advantageous if the data processing unit, in which the processing of the measured values ​​generated inside the depot and a limit value comparison are performed, is equipped to generate an alarm signal and send it to an alarm element when a limit value violation is detected. Such an alarm element is preferably a horn, a loudspeaker, a signal light, and / or a screen. Alternatively or additionally, it is conceivable that the alarm element includes an external data processing unit, a pager, a mobile phone, and / or at least an output unit of a remote monitoring system.According to this specific embodiment of the invention, not only is an automated extinguishing process initiated upon detection of smoke, sparks, gas, and / or flames inside the depot, but a corresponding alarm is also triggered to summon any necessary emergency services. Such an alarm signal can be sent to a central control center, particularly a fire department control center, or distributed to specifically selected or selectable recipients. Additionally, it is conceivable that different agencies could be alerted based on priorities stored in the data processing unit, ensuring that the responsible and necessary agencies are always immediately informed of any fire in the depot.In an advantageous way, information about the condition of the depot as well as special parameters of the atmosphere inside the depot, such as temperature, pressure and gas composition, are transmitted together with the alarm signal.

[0034] According to another specific embodiment, it is conceivable to capture an image or a sequence of images of the depot interior and to provide corresponding images for monitoring the depot. In this context, it is conceivable that at least one image of the depot interior is transmitted together with the alarm signal, so that monitoring personnel can quickly obtain current information about the condition of the vehicle inside the depot. Generally, capturing and providing images has the advantage that information from the depot interior can be obtained without having to open the door. For this purpose, a suitable camera or detector, which could also be an infrared detector, is provided.When using a suitable detector, it is also conceivable that it could be used as an alternative or supplement to at least one other sensor unit inside the depot to detect an alarm, i.e., the formation of smoke, sparks, gas, and / or flames inside the depot. In this case, the data evaluation unit preferably has suitable image processing capabilities and can decide, based on the image data transmitted from inside the depot and the measured values ​​generated by at least one sensor unit, whether an alarm has occurred.

[0035] Furthermore, in this context it is advantageously conceivable that the data processing unit, which has at least one sensor unit and / or one camera unit, has an interface for unidirectional or bidirectional data communication with a remote monitoring system.

[0036] As the above explanations show, a depot designed according to the invention offers the possibility of ensuring preventative fire protection for parked vehicles involved in accidents. To ensure that such a depot can be used safely even during a power outage, it preferably has both an internal power supply and a fire extinguishing agent supply, so that the depot can be operated safely even during a brief interruption of the power or water supply. Likewise, the essential components, such as the door element or the provided actuating elements, such as inlet and outlet valves, can also be operated manually in an emergency.

[0037] The invention further relates to an arrangement or quarantine area for storing, securing, examining, and dismantling a vehicle, in particular a vehicle with an electric drive motor, wherein the arrangement comprises at least one storage area configured according to at least one of the previously described embodiments. In particular, the further invention relates to an arrangement for storing, examining, and dismantling a vehicle with an electric drive motor, comprising at least one exterior area and at least one interior area, wherein the exterior area and the interior area each comprise at least one coalescing separator and a base plate, the base plate being impermeable to hazardous substances, characterized in that the arrangement comprises at least the following elements: i) Depot according to claim 1, ii) Immersion tank containing a fire extinguishing fluid for the rapid submersion of a vehicle having an electric drive motor, iii) Dismantling workshop for the dismantling of battery units of a vehicle having an electric drive motor.

[0038] The arrangement therefore includes at least one depot for storing the vehicle, at least one immersion tank containing or fillable with extinguishing fluid for the rapid submersion of the vehicle, and at least one dismantling workshop for dismantling battery units.

[0039] The arrangement according to the invention comprises a dipping tank, wherein the dipping tank is preferably designed with four walls and a bottom and has a depth of at least 100 cm, particularly 120 cm. The dipping tank is filled with, or can be filled with, a fire extinguishing fluid. Preferably, the dipping tank includes an outlet and an inlet for the fire extinguishing fluid.

[0040] The arrangement according to the invention further comprises a dismantling workshop for removing the battery units from the electric vehicles and for any subsequent inspection of the damaged vehicles. In particular, the dismantling workshop is equipped with non-conductive floors and may include high-voltage work platforms, electromobility-specific equipment including special tools and / or general fire protection and safety precautions or combinations thereof.

[0041] The arrangement according to the invention can further comprise a separate workshop for official inspections, preferably an enclosed, inaccessible interior area of ​​the arrangement. In particular, the workshop for official inspections is equipped with non-conductive floors and can include high-voltage work platforms, electromobility-specific equipment including special tools and / or general fire protection and safety precautions or combinations thereof.

[0042] The arrangement according to the invention can further comprise a training room as an additional element. This could be office space for administration and further training opportunities for, for example, workshop personnel, fire brigades and other authorities.

[0043] The arrangement according to the invention can further comprise an interior area for battery capacity tests. This can, in particular, be a separate testing and inspection hall, where individual measurements of electric vehicle batteries can be carried out to determine their storage capacity or any damage.

[0044] The arrangement according to the invention can further comprise a storage space for removed batteries as an additional element.

[0045] The invention will now be explained in more detail with reference to specific embodiments and the figures, without limiting the general concept of the invention. The figures show: Fig. 1: Perspective view of a depot designed according to the invention with the door element open; Fig. 2: Frontal view into the interior of a depot designed according to the invention through the door opening with the door element open; and Fig. 3: Perspective view of an arrangement designed according to the invention (quarantine space).

[0046] Fig. 1Figure 1 shows a perspective view of a depot 1 designed according to the invention, with a door element 6 in the form of a flap that is folded downwards by slightly more than 90° from the vertical and, in the closed position, seals the depot interior 7 in a fluid-tight manner. In the open position, it is possible to bring a vehicle into the depot interior 7 via the lowered flap, which simultaneously forms a ramp for the vehicle to be brought in. If the vehicle, which is usually a motor vehicle with an electric drive, that was actively or passively involved in an accident (e.g., while parked at the roadside), is no longer roadworthy, it can be pulled into the depot interior 7 using a winch cable 20. For this purpose, an electrically driven winch 20 is attached to the rear side wall 4 inside the depot interior 7.Once the towing cable has been unwound to the required length from the drum of the winch 20, it can be attached to the wrecked vehicle, which can then be pulled into the interior 7 of depot 1 via the door element 6, which in this case forms a ramp. After the wrecked vehicle is in a parked position inside depot 1, the depot 1 flap is swung upwards, thereby sealing the door opening 5.

[0047] The type of vehicle parked in depot interior 7 is entered via a data input unit, allowing relevant vehicle data, such as dimensions, capacity, and the location of any installed battery, to be read from a data storage device 15 and made available to a data evaluation unit. Furthermore, the data evaluation unit has access to permissible values, particularly for the temperature in depot interior 7 and the gas composition.

[0048] Furthermore, seven different sensor units 9 are arranged inside the depot, which can detect the current temperature, the formation of flammable gas atmospheres, and the generation of smoke, flames, and sparks. The measured values ​​generated by these sensor units are transmitted via a wireless data transmission link to the data evaluation unit 10, where a comparison is made between the received measured values ​​and the boundary markets available to the data evaluation unit. During data evaluation, key parameters prevailing in the environment, in particular the outside temperature, are taken into account.

[0049] As soon as the data evaluation unit 10 detects a limit violation, a fire extinguishing fluid, for example, water or carbon dioxide, is introduced from a fire extinguishing agent reservoir 13 located on the roof 2 into the depot interior via the fluid inlet 8. Depending on the vehicle type and the detected limit violation, either the depot interior 7 is completely flooded or the fire extinguishing fluid is directed towards the source of the fire through nozzles. Simultaneously, an alarm signal is generated, thus informing the responsible monitoring person of the outbreak of the vehicle fire.

[0050] With the help of the in Fig. 1The illustrated depot 1 thus allows for particularly effective preventive fire protection measures. This is especially important for accident vehicles with electric drives and corresponding batteries, as accident-related deformation of the battery box can lead to a short circuit, which in turn can cause smoke or fire. Furthermore, depot 1 has rollers 21 at the rear and a crane eye, so that this depot 1, in the form of a roll-off container, can be pulled onto a transport vehicle as needed and is therefore suitable for both the safe stationary storage and the safe transport of an accident vehicle.

[0051] Additionally, it shows Fig. 2A view of the open depot interior 7, in which various sensor units 9 and a camera unit 19 are arranged for visual monitoring. If these sensor units 9 and / or the camera unit generate measured values ​​based on which a limit value is exceeded in the data evaluation unit 10, the data evaluation unit 10 generates a control signal to actuate an actuator 11, so that a flow channel between the extinguishing agent reservoir 13 on the roof 2 and the fluid inlet, for example in the form of a sprinkler or a movable extinguishing nozzle, is opened.

[0052] Depending on the vehicle parked in the interior of depot 7, extinguishing water with or without extinguishing agent additives, foam, and / or a non-flammable gas, preferably carbon dioxide, is selectively introduced into the interior of depot 7. It is generally conceivable to completely flood the interior of depot 7, or at least the source of the fire in the parked vehicle, with the extinguishing fluid, or to direct it specifically to certain points or areas within depot 7.

[0053] Simultaneously with the detected exceedance of the limit value, an alarm signal is generated in the data evaluation unit 10 and transmitted both to the control center of a neighboring fire department and to the operator of depot 1.

[0054] The sensor units 9 arranged in the interior of the depot 7 are equipped with temperature sensors, gas detectors, smoke detectors, flame detectors, and pressure gauges. Furthermore, a camera unit 19, which captures a three-dimensional image of the depot interior 7 and / or takes infrared photographs, is provided to determine the location of fire sources within the depot. The measurement data generated by these sensor units 9 and the camera unit 19 are transmitted to the data evaluation unit 10 and compared there with corresponding limit values. These limit values ​​are transferred from a data storage device 15 to the data evaluation unit 10, depending on the type of vehicle parked in the depot.

[0055] On the roof 2 of depot 1 is a fire extinguishing fluid reservoir 13, which has tanks for extinguishing water and foam on one side and pressurized gas cylinders for storing carbon dioxide on the other. In the event of a fire, the required fire extinguishing fluid is introduced from the fire extinguishing fluid reservoir 13 into the interior of the depot 7 via suitable fluid inlets 8. The fire extinguishing fluid is introduced in such a way that it is directed primarily into an area where the vehicle's batteries are located.

[0056] Furthermore, the depot has a fluid drain 16 in the base 3, through which excess fire extinguishing fluid can be drained from the depot interior or pumped out using a pumping unit. Depending on the applicable local regulations, in particular water and wastewater regulations, one or more filter elements may be provided to ensure that the fire extinguishing fluid can be disposed of properly, for example in a wastewater system. The depot also features [the following features / devices / etc.]. Figure 1 and 2 The depot shown is each equipped with a smoke extraction system through which smoke gases forming in the depot interior 7 in the event of a fire can be safely discharged into the environment, preferably via suitable filter elements. Preferably, the smoke gas extraction is pressure-controlled depending on an overpressure prevailing in the depot interior 7.

[0057] It is essential that the depicted depots can be operated completely autonomously, at least for a certain period of time, as they are equipped with a fire extinguishing fluid reservoir 13, an energy storage system, and all necessary piping and power supply lines. The depots shown can therefore be operated, at least temporarily, even when no external power supply is available.

[0062] For the purposes of this description, "battery" is the generic term for energy storage devices. In electric cars, the required energy is stored primarily in so-called accumulators, or simply accumulators. The electric motor converts this electrical energy into kinetic energy. Specifically, the term "battery" in this context refers to lithium-ion (Li-ion) batteries, lithium-polymer batteries, and / or nickel-metal hydride batteries. A lithium-ion accumulator (also lithium-ion battery, lithium-ion secondary battery, or simply lithium accumulator) is the generic term for accumulators based on lithium compounds in all three phases of the electrochemical cell. The reactive materials—in both the negative and positive electrodes as well as in the electrolyte—contain lithium ions. Reference symbol list
