Description

The invention relates to a depot for storing a vehicle and/or a battery, in particular a vehicle with an electric drive motor. Furthermore, the invention relates to an arrangement or a quarantine place for storing, securing, examining and dismantling a vehicle and/or a battery, in particular a vehicle with an electric drive motor, which has a suitable depot. The depot has a roof, a floor, side walls and a door opening that can be closed by a door element for bringing the vehicle in and out. The roof, floor, side walls and, in the closed state, the door element delimit a depot interior at least in a liquid-tight manner, with at least one controllable fluid inlet also being provided, through which at least one fluid can be directed when a definable event occurs, in particular if smoke, sparks and/or flames form can be introduced into the interior of the depot as an extinguishing agent.

The proportion of motor vehicles on the road that have an electric motor, either as a purely electric drive or as part of a hybrid drive, is constantly increasing. It must be taken into account here that the use of motor vehicles with electric drives results in special, previously non-existent requirements with regard to the procedure in traffic accidents to protect people and the environment. These new challenges are usually based on the use of battery cells in the vehicles, which require special treatment or a special procedure in the event of an accident or other breakdown. The manufacturer specifications currently in force from the major vehicle manufacturers stipulate that after an accident with deployed airbags, the entire battery unit must be removed and subjected to a visual inspection.

Furthermore, there is always the risk that parts of the energy supply, in particular the battery box units, have become deformed as a result of a traffic accident, so that the risk of short circuits occurring and thus a vehicle fire also exists a long time after the actual accident. This risk therefore also exists when the vehicle is parked and regardless of whether a vehicle was actively or passively involved in an accident, for example as a vehicle parked at the side of the road. For the above reasons, vehicle manufacturers require their contractual partners to provide so-called quarantine areas where vehicles involved in an accident or damaged in any other way can be parked. According to the regulations applicable in Germany, an area of 218.75 m ² is required for such a quarantine area. Since the vehicle manufacturers require that each contractual partner must provide two of these quarantine areas, this means that the contractual partners, especially vehicle workshops, must provide an area of almost 440 m ² for such quarantine areas. Especially in the inner-city area, this often means a comparatively high financial burden for the contractual partners.

In addition, it should be noted that the respective quarantine areas must also comply with the applicable regulations with regard to environmental and fire protection regulations. According to the currently applicable recommendations or regulations, it should be guaranteed that the areas are not visible to customers, are easily accessible for rescue vehicles, have a barrier to neighboring areas, offer protection against moisture, especially rain, have a solid subsoil and the comply with applicable water law provisions.

In addition to parking and storing accident vehicles with electric drives, the removal of such vehicles from the scene of the accident also requires a high level of security. Ultimately, it must also be expected that a vehicle will catch fire while it is being transported from the scene of the accident to the quarantine area.

There is therefore a general problem that vehicles which have an electric drive and were involved in an accident can catch fire at the scene of the accident, during transport or only after they are in a parking space, in particular a quarantine area. For this reason, it should be possible to monitor an accident vehicle with an electric drive as seamlessly as possible and to be able to extinguish it quickly and efficiently in the event of a fire during the entire period of time mentioned above, in order to reduce the risk of danger to people and objects in the vicinity and to the environment to minimize.

In this context, from the EP 3 744 406 A1 a special recovery device for vehicles with electric drive and batteries known as energy storage. The salvage facility described has a container that can be filled with extinguishing water and can be closed to accommodate a vehicle. One end of the container is designed as a watertight lockable door. Furthermore, the container has a cable winch to be able to pull a vehicle into the interior when the door is open and a movable lid with which the upper opening of the container can be closed tightly if necessary.

With the help of the recovery device described, it is possible to pull an accident vehicle, in particular a burning electric vehicle, into the open container using the winch, to close the door of the container and then to flood the interior with extinguishing water. Since special additives are often added to the fire-fighting water, it is possible after flooding to close the upper opening of the container with the movable lid and transport the container filled with the vehicle and fire-fighting water away from the scene of the accident. However, the problem with the recovery device described is that neither monitoring of a vehicle parked in the container nor extinguishing while driving is possible. Rather, it is always necessary for people to be present in order to detect the outbreak of a fire, to close the container and to flood the interior with extinguishing water.

Taking into account the solutions known from the prior art, both for parking and storing vehicles with electric drive or for their transport, it is a significant disadvantage that no preventive fire protection measures are taken. In particular, the known solutions do not allow a quick and effective reaction to an emerging fire. It is a regular problem here that vehicles with electric drives can still ignite long after an accident, sometimes even 48 hours later, due to a short circuit in the batteries and the sparks and heat generated as a result.

Proceeding from the technical solutions known from the state of the art and from the problems described above, the object of the invention is to create a depot and to provide an arrangement by which an accident vehicle with an electric drive can be safely parked, stored, transported, inspected and dismantled without the danger that there is a risk of persons and objects in the vicinity and the environment being endangered in the event of a fire to be brought. The area in which the vehicle is kept or parked should be relatively small compared to the known quarantine areas, so that there are advantages in terms of space requirements. Furthermore, the device to be specified should be designed with regard to preventive fire protection and thus ensure that an accident vehicle with an electric drive can be parked safely and isolated from the environment and also be quickly recognizable when there is a risk of fire. In the event of a fire, the fire on the vehicle parked in the depot should be extinguished as quickly and effectively as possible, with hazards to people, animals and plants in the vicinity of the depot and to the environment, in particular due to smoke development and/or the extinguishing agent used, being at least largely ruled out must. In this context, fire should be detected as quickly as possible and without the need for human intervention, and appropriate measures to extinguish or smother the fire should be taken. In addition, the requirements resulting from the applicable fire and immission control regulations and the water protection regulations should be able to be taken into account in a comparatively simple manner. Furthermore, the technical solution to be specified should be characterized by a relatively simple structural design, immunity to faults, even under different conditions, and user-friendliness, preferably with a high degree of automation.

Furthermore, a vehicle should preferably not only be parked and stored safely on a closed site, but should preferably also be able to be checked and dismantled using the arrangement according to the invention.

The object described above is achieved with a depot according to claim 1 and an arrangement according to claim 15. Advantageous embodiments of the invention are the subject matter of the dependent claims and are explained in more detail in the following description with partial reference to figures.

The invention initially relates to a depot for storing and/or transporting a vehicle that has at least one electric motor as the drive motor. The depot has a roof, a floor, side walls and a door opening that can be closed with a door element for bringing the vehicle in and out, which in the closed state of the door opening delimit a depot interior at least in a liquid-tight manner and has at least one controllable fluid inlet through which a definable event, in particular in the event of smoke, sparks, gas and/or flame formation, at least one fluid can be introduced into the depot interior in order to counteract the occurrence or development of a vehicle fire and/or an explosion as early as possible. According to the invention, the depot has been further developed in such a way that at least one sensor unit is provided, which is set up to generate at least one specific measured value for a temperature, a flame, a smoke, a pressure and/or a gas content in the interior of the depot and one for the measured value to transmit a representative measurement signal to a data processing unit, and that the data processing unit can carry out a comparison between the measured value and an adjustable, selectable, stored and/or transmitted to the data processing unit limit value and, if a limit value is violated, a control signal for actuating an actuating element of the fluid inlet can be generated in order to to conduct the fluid at least temporarily from the fluid supply into the interior of the depot. What is essential about the solution according to the invention is that a vehicle is kept in the closed interior of the depot and if a definable event occurs, in particular if smoke, sparks, flames and/or a specific gas develop, a targeted extinguishing and/or suffocation process can be initiated, without the extinguishing fluid routed into the interior of the depot for this purpose escaping unintentionally from the interior of the depot. With the help of a depot designed according to the invention, preventive fire protection can be implemented in a special way for accident vehicles with an electric drive, in which there is still a risk of ignition even a long time after an accident. Likewise, in the event of a vehicle explosion, it is possible to prevent vehicle parts from getting into the environment and causing a hazard.

In general, it is conceivable that the depot is a bin or container with six boundary walls, at least one of which has a suitable door element or is designed as a door element, for example as a pivoting or folding door. as well it is 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 floor, for example a foundation plate, in such a way that no extinguishing fluid can escape unintentionally from the interior of the depot when it is closed can escape.

In any case, at least one sealing element is provided between the movable door element and the adjoining depot area, which in the closed state of the door element signifies a fluid-tight seal of the interior space from the environment. Depending on the extinguishing fluid used in each case, ie depending on whether a liquid, foam and/or a gas, in particular carbon dioxide, is used, a seal is designed to be gas- and/or liquid-tight.

In a special development of the invention, the fluid inlet and a fluid supply connected to it are designed in such a way that water with or without additives and/or a gas, in particular carbon dioxide, can be introduced into the interior of the depot as the extinguishing fluid, in particular to extinguish developing or existing flames delete or suffocate.

The side walls are preferably 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. The depot is preferably designed in the form of a container or a swap body that has a door or flap 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 interior of the depot.

In a particular embodiment, the depot has at least one crane eyelet, a gripping edge, a pin receptacle, a roller and/or a movable or non-movable stand on at least one outside. A depot designed in this way in the form of a container offers the advantage that the depot is suitable both for storing a vehicle stationary and for transporting it, for example from the scene of an accident to a parking area. Such a depot is at the Load the accident site with the vehicles involved in the accident, take the vehicle inside onto a transport or towing vehicle, fasten it in a transport position and unload it in the area provided for parking the vehicle. 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 drop-off or roll-off container that can be picked up and transported by a suitable vehicle.

The depot designed according to the invention for storing a vehicle that has been involved in an accident or a vehicle that has been damaged in any other way enables early, automated detection of a vehicle fire, thus serving preventive fire protection and ensuring that if a fire breaks out in the depot interior, the fire cannot spread to the surroundings and can be quickly extinguished without endangering the environment. At the same time, the depot enables vehicles with electric drives that were involved in an accident and require appropriate monitoring to be stored in a comparatively space-saving, protected and non-visible manner.

In a special embodiment of the invention, the fluid supply is designed in such a way that a gas, a foam and/or water with or without additives can be introduced into the interior of the depot in a targeted manner through the fluid inlet that can be closed with an adjusting 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 extinguishing fluid can be applied to one or more points or areas of the interior of the depot in a targeted manner.

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 one liquid tank or compressed gas reservoir in which the extinguishing fluid required for an extinguishing process is stored and in the event of an alarm, i.e. when smoke is detected, flames , sparks, gas and/or increased heat generation, is introduced automatically through the fluid inlet into the interior of the depot when the actuating element is open. It is of particular advantage if the fluid supply has at least one tank and/or pressurized gas reservoir attached to the roof and/or a side wall of the depot. Alternatively or in addition, it is conceivable for a tank with the required filling volume to be parked next to the depot and connected to the fluid supply via suitable fluid lines.

The fluid supply preferably also has means for conveying an extinguishing fluid used to extinguish a fire, such as at least one pump and/or a fan, which, together with the required conveying lines, i.e. pipelines and/or hoses, directly on the roof and/or on at least attached to a wall of the depot. In this way, a particularly compact unit is created that allows accident vehicles with an electric drive to be safely stored and prevents major fire damage.

In a special development of the depot according to the invention, the fluid supply has at least one heat exchanger and/or a fluid filter, so that it is generally possible to discharge an extinguishing fluid used to extinguish a vehicle fire in a circulation process through the fluid inlet into the depot interior, through a fluid outlet and after a appropriate material and / or thermal processing to supply the fluid inlet again. Alternatively or in addition, it is conceivable that if smoke, sparks, fire, flames and/or gas initiating an extinguishing process has been developed by the sensor unit in the interior of the depot, the interior of the depot is filled or flooded with the extinguishing fluid, at least in this way far that the vehicle arranged in the interior of the depot, preferably only the seat of the fire, is completely covered by fluid and/or oxygen is displaced from this area. In a very special embodiment, the sensors in the interior of the depot are therefore designed in such a way that the amount of extinguishing fluid introduced into the interior of the depot is limited to the amount required to extinguish or smother the fire.

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

Furthermore, it is advantageous if at least one of the aforementioned walls and/or the door element is provided with a thermal insulation element, so that if a fire breaks out in the interior of the depot, the resulting heat is not directly dissipated to an outer skin of the depot and there is a risk as a result that persons or animals who touch the depot from the outside suffer burns.

In a particular development, a platform suitable for receiving a vehicle is provided in the interior of the depot, which platform can be moved relative to the door opening at least when the door element is open and the door is therefore open. Such a platform makes it possible to move it out of the interior of the depot, park a vehicle on the platform and move it together with the platform into the interior of the depot. For this purpose, rollers, rails and/or hinges are preferably provided on the platform and/or the depot in order to move the platform in a suitable manner relative to the door opening with or without a vehicle parked on it. Irrespective of whether a platform is provided, it is advantageous if the depot provides a ramp element, for example in the area of the door opening, over which a vehicle can be rolled into the depot interior comparatively easily. The at least one ramp element is preferably attached to the depot in the area of the door opening via a hinge or joint and can be folded or pivoted up or down as required.

Furthermore, a special development of the invention provides that at least one traction cable of a cable winch that can be driven manually and/or by a motor is arranged in the interior of the depot. Such a cable winch, which can preferably be operated from the outside and particularly preferably by remote control, enables a vehicle to be brought into the interior of the depot in a simple manner. The cable drum with a drive motor is preferably encapsulated in the interior of the depot, optionally with or without a power supply, while the motor and thus the drum connected to the motor for winding and unwinding the traction cable is controlled remotely via a wireless connection.

According to a further embodiment of the invention, it is conceivable that the at least one sensor unit for detecting a 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.

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

In general, it is conceivable to design a depot according to the invention in different sizes, ie to accommodate passenger cars as well as trucks or commercial vehicles. In this context, it is particularly advantageous if the depot has at least one adjustment element, so that the size of the depot, in particular the interior of the depot, can be changed as required, for example by pulling out at least one side wall.

According to a further embodiment of the invention, a fluid discharge with a fluid outlet is provided for discharging the fluid introduced into the depot interior or located in it from the depot interior into a depot environment. In this case, the fluid discharge is preferably connected at least indirectly to a pipeline of a sewage system. The fluid discharge preferably also has at least one pump, which enables extinguishing fluid to be pumped out of the depot in an automated manner and/or as required. Depending on the extinguishing fluid used and the applicable regulations, it is also conceivable in this context that the fluid discharge should take place in the area of the interior of the depot or outside of the Depot interior, preferably attached to at least one depot wall, has a filter element which enables at least partial filtration and/or even thermal or material processing of the fluid discharged from the depot interior.

Furthermore, a flue gas discharge is advantageously provided, via which a flow channel can be produced at least temporarily between the interior of the depot and an area surrounding the depot for discharging smoke in the interior of the depot. Smoke, steam and/or gas formed in the interior of the depot can be removed in an advantageous manner via such a smoke gas discharge, with at least one filter element preferably being arranged in the smoke gas discharge so that no harmful or environmentally hazardous gases or particles get into the environment of the depot. In this case, the smoke gas evacuation is designed depending on the regulations applicable at the installation site of a depot designed according to the invention.

It is also advantageous if the data processing unit, in which in particular the processing of the measured values generated in the depot interior and a limit value comparison is carried out, is set up to generate an alarm signal and send it to an alarm element when a limit value violation is determined. Such an alarm element is preferably a horn, a loudspeaker, a horn, a signal lamp and/or a screen. Alternatively or in addition, it is conceivable that the alarm element has an external data processing unit, a pager, a mobile phone and/or at least one output unit of a remote monitoring system. According to this special embodiment of the invention, there is not only an automated extinguishing process based on the detection of smoke, sparks, gas and/or flames in the interior of the depot, but also a corresponding alarm, in order to summon any necessary helpers. An alarm signal generated in this way can be sent both to a central control room, in particular the control room of a fire brigade, or distributed to specifically selected or selectable recipients. In addition, it is conceivable for different locations to be alerted as a function of priorities stored in the data processing unit, so that the responsible and required locations are always immediately informed of the occurrence of a fire in the depot. Advantageously, together with the alarm signal, information about the condition of the depot and specific parameters of the atmosphere in the depot interior, such as temperature, pressure and gas composition.

According to a further specific embodiment, it is conceivable to record an image or an image sequence of the interior of the depot and to provide corresponding images for monitoring the depot. In this context, it is conceivable that at least one image of the interior of the depot is transmitted together with the alarm signal, so that monitoring personnel can quickly obtain up-to-date information about the condition of the vehicle in the interior of the depot. In general, the recording and provision of images has the advantage that information can be obtained from the interior of the depot without having to open the door element. A suitable camera or a suitable detector, which can also be designed as an infrared detector, for example, is provided for this purpose. When using a corresponding detector, it is also conceivable that this is used as an alternative or in addition to at least one other sensor unit in the interior of the depot in order to detect an alarm, i.e. the formation of smoke, sparks, gas and/or flames in the interior of the depot. In this case, the data evaluation unit preferably has suitable image processing and can make a decision as to whether an alarm is present on the basis of the image data transmitted from the interior of the depot and the measured values generated by at least one sensor unit.

Furthermore, it is advantageously conceivable in this context 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 system for remote monitoring.

As the above statements show, a depot designed according to the invention offers the possibility of ensuring preventive fire protection with regard to parked accident vehicles. So that a corresponding depot can also be used safely in the event of a power failure, the depot preferably has both an internal energy and extinguishing agent supply, so that a depot can be operated safely even if the power or water supply is briefly interrupted. Likewise, the essential components, such as the door element or the control elements provided, such as inlet and outlet valves, can also be operated manually in an emergency.

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 which is folded down slightly more than 90° from the vertical and in the closed state closes off the depot interior 7 in a fluid-tight manner. In the open state, it is possible to bring a vehicle into the depot interior 7 via the lowered flap, which at the same time forms a ramp for the vehicle to be brought in. If the vehicle, which is usually a motor vehicle with an electric drive and which was actively or passively involved in an accident, i.e. parked on the side of the road, for example, is no longer roadworthy, it can be pulled into the interior 7 of the depot using a traction cable of a cable winch 20 . For this purpose, a cable winch 20 driven by an electric motor is fastened to the rear side wall 4 in the depot interior 7 . As soon as the traction cable has been unwound from the drum of the cable winch 20 to the required length, it can be attached to the accident vehicle and pulled into the interior 7 of the depot 1 via the door element 6 designed as a flap, which in this case forms a ramp. After the accident vehicle is in a parking position inside the depot 1, the flap of the depot 1 is pivoted upwards and the door opening 5 is thereby fluid-tight.

The type of vehicle parked in the depot interior 7 is entered via a data input unit, so that associated vehicle data, such as dimensions and capacity and position of a built-in battery, are read from a data memory 15 and made available to a data evaluation unit. In addition, the data evaluation unit has permissible values, in particular for the temperature in the depot interior 7 and the gas composition.

Furthermore, various sensor units 9 are arranged in the depot interior 7, with which the actual temperature, the formation of flammable gas atmospheres and the formation of smoke, flames and sparks can be detected. The measured values generated by these sensor units are transmitted via a wireless data transmission link to the data evaluation unit 10, in which a comparison is carried out between the measured values obtained and the frontier markets available to the data evaluation unit. When evaluating the data, essential parameters prevailing in the environment, in particular the outside temperature, are taken into account.

As soon as the data evaluation unit 10 detects a limit violation, an extinguishing fluid, for example extinguishing water or carbon dioxide, is introduced from an extinguishing agent reservoir 13 of a fluid supply 12 arranged on the roof 2 through the fluid inlet 8 into the interior of the depot. Depending on the type of vehicle and the detected limit value violation, either the depot interior 7 is completely flooded or the extinguishing fluid is discharged in a targeted manner through nozzles in towards the seat of the fire. At the same time, an alarm signal is generated, informing the person responsible for monitoring that the vehicle fire has broken out.

With the help of the in 1 Depots 1 shown can thus be taken in a particularly effective way preventive fire protection measures. This is particularly important in accident vehicles with an electric drive and batteries provided for this purpose, since deformation of the battery box caused by an accident can lead to a short circuit, which in turn can lead to smoke formation or a fire. Furthermore, the depot 1 has rollers 21 in the rear area and a lifting eye so that this depot 1 can be pulled onto a transport vehicle in the form of a roll-off container if required and can therefore be used both for safe stationary storage and for the safe transport of an accident vehicle is.

Supplementary shows 2 a view of the open depot interior 7, in which different 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, on the basis of which a limit value violation is determined in the data evaluation unit 10, the data evaluation unit 10 generates a control signal for activating an actuating element 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 released.

Depending on the vehicle parked in the interior 7 of the depot, extinguishing water with or without additives for extinguishing agents, foam and/or an incombustible gas, preferably carbon dioxide, is fed into the interior 7 of the depot. It is generally conceivable here to completely flood the depot interior 7 or at least the seat of the fire of the parked vehicle with the extinguishing fluid or to direct this to specific points or areas of the depot interior 7 .

Simultaneously with the detected exceeding of the limit value, an alarm signal is generated in the data evaluation unit 10 and transmitted both to the control room of a neighboring fire brigade station and to the operator of the depot 1.

The sensor units 9 arranged in the depot interior 7 have temperature sensors, gas detectors, smoke sensors, flame detectors and pressure gauges. Furthermore, a camera unit 19, which takes a three-dimensional image of the depot interior 7 and/or creates infrared images, is provided to determine the position of the sources of fire in the interior of 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 here with corresponding limit values. Depending on the type of vehicle that is parked in the interior of the depot, the limit values are transmitted from a data memory 15 to the data evaluation unit 10 .

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

In addition, the depot has a fluid discharge 16 in the floor 3, through which extinguishing fluid that is no longer required can be drained from the interior of the depot or pumped out with the aid of a conveying unit. Depending on the applicable local regulations, in particular the water law and waste water law regulations, one or more filter elements can be provided so that the extinguishing fluid can be disposed of according to regulations, for example in a sewage system. The same applies to the figures 1 and 2 The depot shown each has a smoke gas outlet, via which smoke gas that forms in the depot interior 7 in the event of a fire can be safely discharged into the environment, preferably using suitable filter elements. The smoke gas discharge preferably takes place in a pressure-controlled manner as a function of an overpressure prevailing in the depot interior 7 .

It is essential that the depots shown can be operated completely independently, at least for a certain time, since they have an extinguishing fluid reservoir 13, an energy store and all the necessary pipe and have power supply lines. The depots shown can also be operated at least temporarily if no external power supply is available.

3 shows a perspective view of an arrangement designed according to the invention (quarantine area) with a large number of depots 1, a plunge pool 23 filled with extinguishing fluid and a dismantling workshop 24. All three inner areas are connected to one another via an outer area 25.

Battery in the sense of the present description is the generic term for energy storage. In electric cars, the energy required is stored in particular by so-called accumulators, or batteries for short. The electric motor converts this electric energy into kinetic energy. In particular, the term “battery” in connection with the present description means lithium-ion rechargeable batteries (Li-ion), lithium-polymer rechargeable batteries and/or nickel-metal hydride rechargeable batteries. A lithium ion accumulator (also called lithium ion accumulator, lithium ion accumulator, lithium ion secondary battery or lithium accumulator for short) is the generic term for accumulators based on lithium compounds in all three phases of the electrochemical cell. The reactive materials - both in the negative and in the in the positive electrode as well as in the electrolyte - contain lithium ions.
