Abstract

The present disclosure relates to a system for an energy store of a vehicle, comprising at least one carrying module which can be fastened to a vehicle, the at least one carrying module comprising an interior which is set up to accommodate at least one energy store of the vehicle; and at least one inlet, which is arranged on an outside of the at least one support module and is connected to the interior, wherein the at least one inlet is set up such that an extinguishing medium provided by a device can be introduced into the interior of the at least one support module.

Description

The present disclosure relates to a system for an energy storage device of a vehicle and a vehicle with such a system. In particular, the present disclosure relates to an extinguishing system for traction batteries, for example of trucks.

State of the art

Hydrogen, hybrid or electric vehicles are driven by an electric motor, with the necessary electrical energy being stored in an energy storage device, such as a high-voltage storage device. The energy storage device can be charged at a charging station in a house or at a special gas station.

If the hydrogen, hybrid or electric vehicle is involved in an accident, the energy storage device may catch fire. Extinguishing the fire is often only possible by withdrawing heat from the energy storage device. For example, a Li battery generates oxygen itself when heated, so that external oxygen in the air is not necessary to enable the Li battery to burn.

Electrically powered passenger cars that have caught fire can be completely immersed in a large container with extinguishing agent and remain there until the ignited energy storage device has burned out. The car can then be transported away in a container filled with extinguishing agent, for example.

However, deleting an ignited energy store in this way is complex and destroys the entire vehicle. In the case of larger vehicles, it may also be impossible to sink and/or transport them away in a container filled with extinguishing agent.

Disclosure of Invention

It is an object of the present disclosure to specify a system for an energy storage device of a vehicle and a vehicle with such a system, which can increase safety of a vehicle with an electric drive. In particular, it is an object of the present disclosure to enable energy stores that have caught fire to be extinguished.

This object is solved by the subject matter of the independent claims. Advantageous configurations are specified in the dependent claims.

According to an independent aspect of the present disclosure, a system for an energy store of a vehicle, in particular a truck, is specified. The system includes at least one support module that can be attached or is attached to a vehicle, wherein the at least one support module includes an interior space that is set up to accommodate at least one energy store of the vehicle; and at least one inlet, which is arranged on an outside of the at least one support module and is connected to the interior, wherein the at least one inlet is set up such that an extinguishing medium provided by a (e.g. external) device can be introduced into the interior of the at least one support module .

According to the invention, at least one inlet is provided on the support module of the energy store, through which the extinguishing medium or extinguishing agent can be introduced into the support module as required. The extinguishing medium can be introduced non-destructively and non-violently into the carrying module of the energy store. In addition, the extinguishing personnel, such as the fire brigade, can keep a distance from the energy storage device that has caught fire or greatly reduce the time spent in the vicinity of the burning energy storage device.

The vehicle is an electric vehicle, such as a hydrogen, hybrid, or electric vehicle. The term vehicle includes cars, trucks, buses, mobile homes, motorcycles, etc., which are used to transport people, goods, etc. In particular, the term includes trucks for transporting goods. Driverless vehicles, i.e. autonomous or partially autonomous vehicles, are also included.

The at least one support module is connected to the vehicle by at least one mechanical connection. For example, the at least one support module can be connected to a frame of the vehicle. The support module preferably forms an interior space and can also be referred to as a housing. In most cases, the interior is completely closed. However, it is also possible to use a support module which interacts with components of the vehicle in such a way that an interior space is formed, e.g. in which one side of the support module bears against a housing wall of the vehicle.

In some embodiments, the mechanical connection can include or be a form-fitting connection and/or a force-fitting connection. For example, the mechanical connection can be selected from the group consisting of a screw connection, a bolt connection, a clamp connection, a dovetail connection bond, a welded joint, and combinations thereof, or consists thereof.

The at least one support module is preferably a frame or housing, which at least partially, preferably completely, encloses the at least one energy store. In particular, the at least one support module can be a closed battery housing.

The terms “extinguishing medium” or “extinguishing agent” as used within the scope of the present disclosure designate a medium that is suitable for extracting heat from the at least one energy store. The extinguishing medium can be, for example, a solid extinguishing medium (e.g. sand, extinguishing powder), a liquid extinguishing medium (e.g. water), a gaseous extinguishing medium (e.g. nitrogen), a foam or gel-like extinguishing medium (e.g. extinguishing foam) and/or a coolant (e.g. to non-burning batteries in a hot environment to prevent a chain reaction (thermal runaway) as a precaution).

In some embodiments, the erasing medium may exhibit electrically conductive properties or electrically non-conductive (i.e., electrically insulating) properties. The electrically insulating properties can reduce the risk of an internal short circuit, e.g. in the event of a battery damaged in an accident.

The extinguishing medium is preferably provided externally, e.g. by the fire brigade. In this case, the device that provides the extinguishing medium can be an external device, such as a tanker truck or a hydrant, which is connected with a hose to the extinguishing agent connection on the battery side. It can thereby be ensured that the extinguishing medium can be provided in sufficient quantity to withdraw heat to a sufficient extent from the at least one energy store.

In other embodiments, the extinguishing medium can be carried on the vehicle. In this case, the device that provides the erasing medium may be an internal device. The internal or on-board device can, for example, be a container in which the extinguishing medium is stored or stored. In some embodiments, the container can be connected via an extinguishing line to the at least one support module for introducing the extinguishing medium into its interior. This enables the container to be installed at a suitable installation site on the vehicle, regardless of the position of the at least one energy store.

The at least one inlet can be temporarily connected to the external device, such as a fire hose, in order to flood the at least one energy store with the extinguishing medium.

Alternatively, the at least one inlet can be permanently connected to the internal device, such as the container and/or the extinguishing line connected to the container, in order to flood the at least one energy store with the extinguishing medium during an emergency.

The at least one inlet can preferably be built into the vehicle as standard or retrofitted.

The at least one inlet is preferably designed as a connection. For example, the connection can be in the form of a thread, C connection, GK connection, quick coupling, etc., but is not limited to these examples.

Preferably, the at least one inlet is arranged to be detachably connected to the external device, such as a fire hose. The at least one inlet and the fire hose may be configured according to DIN 14811 in some embodiments.

The at least one inlet is preferably designed as a one-way valve. In some embodiments, the one-way valve may be a check valve, for example to prevent gas leakage. The check valve can be a spring-loaded check valve, for example, in order to prevent dust and/or moisture and/or liquids from penetrating into the interior of the at least one support module under normal operating conditions.

The at least one inlet is preferably set up such that the extinguishing medium impinging on the at least one inlet from the outside can pass through the at least one inlet. For example, the at least one inlet can be designed as a one-way valve with a flap that swings in one or two directions, similar to a "cat flap". This means that the extinguishing medium can be injected through the flap into the interior of the carrying module, e.g. using an “extinguishing agent cannon” such as a water cannon.

The one-way valve is easily accessible from the outside and can be hit by an "extinguishing agent launcher". Thus, firefighters do not have to approach the vehicle to connect the fire hose to the extinguishing agent connection, thereby endangering the fire firefighters can be reduced or even avoided altogether

The at least one inlet, in particular the “cat flap”, can preferably be secured or closed by a breaking element. If necessary, the rupture element can be destroyed by applying a mechanical force, e.g. by the pressure jet of the "extinguishing agent cannon". In some embodiments, the rupture element may comprise or be a sheet of glass.

The system preferably further comprises at least one outlet, which is arranged on the at least one support module and is connected to the interior. The at least one outlet is set up so that the extinguishing medium introduced into the interior can be led out of the interior. As a result, the extinguishing medium can be selectively introduced through the at least one inlet and discharged through the at least one outlet, so that a flow through the at least one energy store can be achieved.

An extinguishing agent circuit can be provided by the at least one inlet and the at least one outlet, as a result of which heat can be efficiently extracted from the at least one energy store. For example, after flowing through the energy store, the extinguishing medium can be cooled again and reintroduced into the interior of the energy store. A quantity of the required extinguishing medium can thus be reduced.

Preferably, the at least one inlet is located higher than the at least one outlet, for example with respect to a vertical direction. The term "vertical" is to be understood differently from "horizontal". The term "vertical" refers in particular to a vertical alignment of the at least one inlet with respect to the at least one outlet, with a deviation of a few degrees, e.g. up to 5° or even up to 10°, from a precise vertical alignment still being considered considered "substantially vertical". The vertical direction may be substantially parallel to gravity.

In some embodiments, the at least one inlet is exactly one inlet. Alternatively, the at least one inlet can be two or more inlets. For example, there can be one inlet or two or more inlets per support module and/or per energy store.

Additionally or alternatively, the at least one outlet is exactly one outlet. Alternatively, the at least one outlet can be two or more outlets. For example, there can be one outlet or two or more outlets per support module and/or per energy store.

Preferably, a number of inlets is equal to a number of outlets.

Preferably, the system further comprises at least one pressure equalization valve that is set up to let air out of or in from the interior, e.g. In this way, it can be achieved that the extinguishing medium flows more quickly to the energy stores and is not forced back or slowed down by counter-pressure within the interior. Such a back pressure could, for example, be caused by air in the cavities of the energy store or be increased when the energy store is burning, for example by generating gases.

The interior of the at least one support module is preferably set up to accommodate two or more energy stores of the vehicle. The extinguishing medium can be fed to the two or more energy stores individually or simultaneously.

The at least one support structure preferably comprises two or more support modules, each support module of the two or more support modules being set up to support or accommodate one or more energy stores of the vehicle. In other words, the system according to the embodiments of the present disclosure can comprise a support structure with a multiplicity of support modules, with each support module carrying at least one energy store.

For example, a total of six batteries can be installed on a truck. Two batteries each can be arranged on the left and right of the vehicle frame, between the two axles, and protected by side impact protection. Two further batteries can be arranged in the middle of the vehicle, whereby one battery can be arranged in front of, behind or at the height of the front axle and another battery can be arranged between the front and the rear axle of the vehicle.

The two or more support modules can preferably be flooded together or simultaneously with the extinguishing medium. In other embodiments, the two or more support modules can be flooded with the extinguishing medium independently of one another, in particular one after the other.

The system can preferably include a triggering mechanism which is set up to trigger or start the introduction of the extinguishing medium from the container into the interior of the at least one carrying module.

According to a further independent aspect of the present disclosure, a vehicle, in particular a truck, is specified. The vehicle includes the system according to the embodiments of the present disclosure and the at least one energy store.

The vehicle is an electric vehicle, such as a hydrogen, hybrid, or electric vehicle. The hydrogen, hybrid, or electric vehicle may be a pure electric vehicle (BEV) or a plug-in hybrid vehicle (PHEV) according to embodiments. The energy store (e.g. battery or traction battery) is provided as the energy supply for the electric drive and can, for example, be connected to a charging station and charged via a charging device in the vehicle.

The term vehicle includes cars, trucks, buses, mobile homes, motorcycles, etc., which are used to transport people, goods, etc. In particular, the term includes trucks for transporting goods.

Embodiments of the Disclosure

Unless otherwise noted, the same reference symbols are used below for the same elements and those with the same effect.

1 1 shows a front perspective view of a system 100 for an energy storage device 10 of a vehicle according to exemplary embodiments of the present disclosure. 2 10 shows a rear perspective view of a system 100 for an energy storage device 10 of a vehicle according to example embodiments of the present disclosure.

The vehicle may be a truck, but the present disclosure is not so limited.

The system 100 includes at least one support module 110 that can be attached or is attached to a vehicle, wherein the at least one support module 110 includes an interior space that is configured to accommodate at least one energy store 10 of the vehicle; and at least one inlet 120, which is arranged on an outside of the at least one support module 110 and connected to the interior, wherein the at least one inlet 120 is set up so that an extinguishing medium provided by a (e.g. external) device can enter the interior of the at least one Support module 110 can be introduced.

The connection between the at least one inlet 120 and the interior is a fluid connection, so that the extinguishing medium can enter the interior essentially unhindered and flow around the at least one energy store 10 of the vehicle.

The extinguishing medium can be, for example, a solid extinguishing medium (e.g. sand, extinguishing powder), a liquid extinguishing medium (e.g. water), a gaseous extinguishing medium (e.g. nitrogen), a foam or gel-like extinguishing medium (e.g. extinguishing foam) and/or a coolant (e.g. to non-burning batteries in a hot environment to prevent a chain reaction (thermal runaway) as a precaution).

The erasing medium may have electrically conductive properties or electrically non-conductive (i.e. electrically insulating) properties. The electrically insulating properties can reduce the risk of an internal short circuit, e.g. in the event of a battery damaged in an accident. The electrically conductive properties can create an internal (high resistance) short circuit of the modules and discharge the electrical storage, reducing the potential risk of ignition.

In some specific embodiments, the interior of the at least one carrying module 100 is set up to accommodate two or more energy stores 10 of the vehicle. The extinguishing medium can be supplied to the two or more energy stores 10 individually or simultaneously.

The at least one support module 110 is connected to the vehicle by at least one mechanical connection. For example it can at least one support module 110 can be connected to a frame 20 of the vehicle by the at least one mechanical connection.

In some embodiments, the mechanical connection can include or be a positive connection and/or a frictional connection. For example, the mechanical connection may be selected from the group consisting of or consisting of a screw connection, a bolt connection, a clamp connection, a dovetail connection, a welded connection, and combinations thereof.

The at least one support module 110 can be a frame or housing which encloses the at least one energy store 10 . The at least one support module 110 can at least partially, preferably completely, enclose the at least one energy store 10 . In particular, the at least one support module 110 can be a battery housing.

In some embodiments, the at least one support module 110 comprises two or more support modules, each support module of the two or more support modules being set up to accommodate one or more energy stores 10 of the vehicle. In other words, the system 100 can include a support structure with a large number of support modules, with each support module 110 accommodating at least one energy store 10 in its interior.

The two or more support modules 110 can be flooded together or simultaneously with the extinguishing medium. In other embodiments, the two or more support modules 110 can be flooded with the extinguishing medium independently of one another, in particular one after the other.

In some embodiments, each support module 110 comprises two main sides 112 and four secondary sides 114. Preferably, the two main sides 112 and/or two secondary sides 114 are arranged on opposite sides of a respective support module 110.

The at least one inlet 120 can be arranged on a secondary side of the four secondary sides 114 , and in particular on the secondary side facing away from the frame 20 . The secondary side facing away from the frame 20 and on which the at least one inlet 120 is provided can be a substantially vertical secondary side of the support module 110 . The at least one inlet 120 can thus be easily reached by the extinguishing personnel from the outside.

In some embodiments, the system 100 further includes at least one outlet 130 disposed on the at least one support module 110 and connected to the interior. The at least one outlet 130 is set up so that the extinguishing medium introduced into the interior can be guided out of the interior. As a result, the extinguishing medium can be introduced into the interior in a targeted manner through the at least one inlet 120 and discharged through the at least one outlet 130, so that an efficient flow through the at least one energy store 10 can be achieved.

An extinguishing medium circuit can be provided by the at least one inlet 120 and the at least one outlet 130, as a result of which heat can be efficiently extracted from the at least one energy store 10. For example, the extinguishing medium can be cooled again after flowing through the energy store 10 and reintroduced into the interior of the energy store 10 . A quantity of the required extinguishing medium can thus be reduced.

In some embodiments, the at least one inlet 120 and the at least one outlet 130 can be arranged on the same secondary side 114 of the support module 110 . In other embodiments, the at least one inlet 120 and the at least one outlet 130 can be arranged on different sides 112 and/or 114 of the support module 110 . The inlet 120 and/or outlet 130 may also be mounted on the vehicle for easy accessibility, e.g., both at the front or both at the rear of the vehicle, or one port at the rear and the other port at the front. An arrangement on one or both outer sides, e.g. the side panels or the side impact protection, is also possible.

In order to ensure easy or safe access to the inlet 120 and/or the outlet 130 in as many situations as possible in the event of an accident, it is advantageous to arrange connections for the inlet 120 and/or the outlet 130 on different or all sides of the vehicle. The connections are normally closed and can be opened if necessary. It is thus also possible to introduce and/or discharge extinguishing agent from different sides of the vehicle.

The extinguishing agent is then routed to the carrying module or into the interior of the carrying module via one or more pipelines which are connected to the at least one inlet 120 and/or outlet 130 . This makes it easier for the fire brigade to bring the extinguishing agent into the carrying module. When using several carrier modules, extinguishing agent can be supplied centrally to all carrier modules. little At least the inlet of a support module should be routed to the outside in order to create a quick connection option. If necessary, the outlet can also remain directly on the support module. When using a circulation of the extinguishing agent or a closed circuit of the extinguishing agent, the outlet should also be accessible easily or if possible on the same side in order to feed the extinguishing agent removed from the carrying module again via the inlet. If necessary, the extinguishing agent can be cooled down and/or processed before it is fed in again. It is also possible to connect several support modules sequentially one behind the other in order to introduce the extinguishing agent sequentially from a first support module to the subsequent support module, etc. A parallel supply of extinguishing agent to several carrying modules is more efficient.

Typically, the at least one inlet 120 is located higher than the at least one outlet 130, e.g., with respect to the vertical direction. As a result, the extinguishing agent can be discharged from the interior of the support module 110 solely by the effect of gravity.

In some embodiments, the at least one inlet 120 may include a connection line 122 or be connected to the connection line 122 . For example, the connection line 122 can have a first end and a second end. The first end can be connected to the support module 110, for example welded. The second end may be connected, eg welded, to the inlet 120 . In this way, the inlet 120 can be arranged in a position that is accessible to the extinguishing personnel, even if the support module 110 is in an inaccessible position on the vehicle (e.g. between two supports 20, as in the example in FIG 1 and 2 shown) is arranged.

Additionally or alternatively, the at least one outlet 130 can include a connecting line 132 or can be connected to the connecting line 132 . For example, the connection line 132 can have a first end and a second end. The first end can be connected to the support module 110, for example welded. The second end may be connected, eg welded, to the outlet 130 . As a result, the outlet 130 can be arranged in an accessible position, even if the support module 110 is in an inaccessible position of the vehicle (e.g. between two supports 20, as in the example in FIG 1 and 2 shown) is arranged.

According to some embodiments, the extinguishing medium is provided externally, e.g. by the fire department. In this case, the device that provides the extinguishing medium can be an external device, such as a fire hose. It can thereby be ensured that the extinguishing medium can be provided in sufficient quantity to withdraw heat to a sufficient extent from the at least one energy store 10 . The at least one inlet 120 can be temporarily connected to the external device, such as the fire hose, in order to flood the at least one energy store 10 with the extinguishing medium in an emergency.

For this purpose, the at least one inlet 120 can be designed as a connection. For example, the connection can be in the form of a thread, C connection, GK connection, quick coupling, etc., but is not limited to these examples.

Additionally or alternatively, the at least one inlet 120 can be designed as a one-way valve. For example, the one-way valve can be set up so that the extinguishing medium impinging on the one-way valve from the outside can pass through the one-way valve. For example, the one-way valve can be formed with a flap swinging in one or two directions. This means that the extinguishing medium can be shot through the flap into the interior using an "extinguishing agent cannon", such as a water cannon.

In some embodiments, the at least one inlet 120 may be secured or closed by a rupture element. If necessary, the rupture element can be destroyed by applying a mechanical force, e.g. by the pressure jet of the "extinguishing agent cannon". In some embodiments, the rupture element may comprise or be a sheet of glass.

According to other embodiments, the extinguishing medium can be carried on the vehicle, ie not provided externally. In this case, the device that provides the erasing medium may be an internal device. The internal or on-board device can, for example, be a container in which the extinguishing medium is stored or stored.

In some embodiments, the container can be connected to the at least one support module 110 via an extinguishing line in order to introduce the extinguishing medium into its interior. This enables the installation of the container at a suitable installation location of the vehicle regardless of a position of the at least one energy storage device 10. In this case, the at least one inlet 120 can be permanently connected to the internal device, such as the container and/or the container connected Extinguishing line to be connected to the at least one Energiespei cher 10 with the extinguishing medium during an emergency.

In some embodiments, the system 100 includes a triggering mechanism that is set up to trigger or start the introduction of the extinguishing medium from the container into the interior of the at least one carrying module 110 . The triggering mechanism can be a manual triggering mechanism and/or an automatic triggering mechanism.

For example, the manual trigger mechanism may be operable by a driver or firefighter. For this purpose, in some embodiments, an actuating element such as a button or switch can be present in the interior and/or exterior of the vehicle, which can be actuated by the user in order to trigger or start the introduction of the extinguishing medium into the interior of the at least one carrying module 110 .

The automatic triggering mechanism may be operable by a controller such as a vehicle on-board computer. For this purpose, the system 100 can include at least one emergency detection unit that is set up to detect an existing and/or impending emergency. The emergency may be a vehicle fire, for example. If the emergency detection unit recognizes the existing and/or imminent emergency, the emergency detection unit can actuate the triggering mechanism or instruct it to trigger or start the introduction of the extinguishing medium into the interior of the at least one carrying module 110 .

For example, the emergency detection unit can include one or more sensors that are suitable for detecting the existing and/or impending emergency. For example, the one or more sensors may be selected from or consisting of the group consisting of a temperature sensor and a vehicle speed sensor. The temperature sensor can, for example, detect a temperature in and/or on the energy store.

In some embodiments, the emergency detection unit can actuate or instruct the triggering mechanism to trigger or start introducing the extinguishing medium into the interior of the at least one carrying module 110 when a vehicle speed of zero (e.g. 0 km/h) and/or a temperature is detected equal to or higher than a threshold value.

In some embodiments, the system 100 further includes at least one pressure equalization valve 140 configured to let air in or out of the cabin. This is particularly helpful when the air inside the cabin expands due to temperature fluctuations. However, the pressure compensation valve 140 can also let out the air that is displaced when the extinguishing medium is introduced into the interior of the at least one support module 110 . In this way, it can be achieved that the extinguishing medium flows more quickly to the energy stores 10 and is not pushed back or slowed down by counter-pressure within the interior. Such a back pressure could arise, for example, due to air in the cavities in the support module 110 or when the energy store 10 is burning, for example due to the generation of gases.

In one embodiment, the pressure compensation valve can ensure atmospheric or heat-related pressure compensation. For this purpose, the pressure compensation valve can have a gas-permeable membrane that prevents the ingress of foreign bodies or atmospheric moisture under normal operating conditions. In the event of outgassing or a fire in the battery, the membrane can rupture and expose the full or a larger cross-section.

According to the invention, at least one inlet is provided on the support module of the energy store, through which the extinguishing medium or extinguishing agent can be introduced into the support module as required. The extinguishing medium can be introduced non-destructively and non-violently into the carrying module of the energy store. In addition, the extinguishing personnel, such as the fire brigade, can keep a distance from the energy storage device that has caught fire or greatly reduce the time spent in the vicinity of the burning energy storage device.

Although the invention has been illustrated and explained in more detail by means of preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by a person skilled in the art without departing from the protective scope of the invention. It is therefore clear that a large number of possible variations exist. It is also understood that the embodiments given by way of example are really only examples and should not be construed as limiting in any way the scope, applications or configuration of the invention. Rather, the preceding description and the description of the figures enable the person skilled in the art to concretely implement the exemplary embodiments, whereby the person skilled in the art, knowing the disclosed inventive concept, can make a variety of changes, for example with regard to the function or the arrangement of individual elements mentioned in an exemplary embodiment, without departing from the scope of protection defined by the claims and their legal equivalents, such as further explanations in the description.
