Definitions
- the present invention relates to a module cover hood for battery modules, which ensures that a hot gas stream enriched with conductive particles is safely discharged, which is released from the cell in the event of thermal failure of a battery cell, in order to prevent a short circuit with the formation of an arc between the battery housing ground and live components.
- rechargeable battery systems in particular lithium-ion battery cells
- a large number of battery cells are combined to form a battery module and a number of battery modules are combined to form a battery pack and are electrically connected to one another.
- DE 2018 125 618 A1 discloses a protective unit for the safe electrical interconnection of battery cells to form battery modules and battery stacks for a high-voltage battery for motor vehicles, with a cell contacting system being placed on the cell terminal side of the battery cells, which is formed from an electrically insulating frame and electrically conductive cell connectors introduced therein for the desired interconnection. Between the cell contact system and the cell terminal side of the battery cells there is an electrically insulating intermediate layer with cutouts for the cell terminals to pass through and a series of openings for dissipating hot gas that escapes from the safety valve of the battery cell in the event of a thermal failure of a battery cell located below. The hot gas escaping from the damaged battery cell is discharged via the openings in the intermediate layer and corresponding cutouts in the cell contacting system into a receiving space in the battery housing in which the battery module or battery modules are arranged.
- a strip-shaped, electrically insulating protective mat can extend along and above the openings in the intermediate layer, which protects the current-carrying components of the high-voltage battery from the hot gas and prevents fire or flames from escaping the battery housing.
- DE 102013220 778 A1 describes a battery housing for a vehicle battery, for example a lithium-ion traction battery, which is formed from a polymer composite material to reduce the weight of known such housings which are made of metal.
- a battery housing made from a polymer composite material also has the advantage that it is electrically insulating.
- the battery housing has a battery accommodation space and a cover for placing on the battery accommodation space.
- the cover can have at least one opening for filling the battery, two electrode feedthrough openings for feeding battery electrodes through and/or a predetermined breaking point for degassing the battery.
- the very hot gas also carries with it conductive particles such as graphitic carbon, metallic particles and other decomposition products of the cell contents.
- the avoidance of energy transfer to neighboring cells and modules is essential for the operational safety of the battery cells and in particular also of possible vehicle occupants in order to prevent the thermal runaway from spreading or at least to prevent it for as long as possible.
- the gas which is loaded with conductive particles, leads to a short circuit between the current-carrying components and the ground of the battery pack and from the formation of an arc that can generate temperatures of up to several thousand degrees Celsius. That high Temperatures can no longer be controlled with the insulation materials currently available and inevitably lead to a thermal runaway of the entire battery system within a very short time.
- a suitable protection concept for a battery pack must ensure that no sparks or flames occur outside the battery pack for a period of several minutes after the first sign of thermal runaway has been detected, i.e. become visible. This period of time before flames are visible outside the battery pack should preferably be no less than 5 minutes to meet safety standards.
- the present invention relates to a module cover hood with an integrated gas discharge structure having the features of claim 1.
- the module cover hood according to the invention with integrated gas discharge allows a hot gas flow, loaded with conductive particles, emerging from an overheated cell of a module to be discharged quickly and directly from the battery pack without causing a short circuit and arcing between current-carrying components and the ground of the battery pack.
- the occurrence of visible flames outside the battery pack can thus be prevented for a period of at least 5 minutes and in particular at least 7 minutes and longer, as required for compliance with safety regulations.
- module cover hood according to the invention has very good three-dimensional formability during production, with the advantage that a desired shape can be obtained precisely and without great effort.
- the hot gas loaded with conductive particles can be discharged from the point of origin via the modules out of the battery pack without the conductive gas making contact with it short circuit between the current-carrying components, such as busbars, cell connectors, module connectors, etc. and the ground of the battery pack. This avoids the formation of an arc caused by a short circuit between the housing ground and the current-carrying components via the electrically conductive gas phase formed during a thermal runaway.
- the current-carrying components such as busbars, cell connectors, module connectors, etc.
- the module cover hood according to the invention is intended in particular for the use of battery systems made up of prismatic battery cells, such as are often used in electric vehicles today.
- the module cover hood can easily be modified for other battery types such as pouch cells or cylindrical cells.
- Prismatic cells, battery modules and battery packs made from them and their production are generally known.
- Prismatic cells have a metallic housing, usually made of aluminum or stainless steel, with two electrical contacts on one side surface, with a safety valve being provided between the electrical contacts.
- the safety valve opens as soon as the internal pressure of the cell rises above a defined critical value in order to allow the gas to escape in a directed manner.
- a number of prismatic battery cells that varies as required is combined main surface to main surface one behind the other to form a battery module.
- the module cover according to the invention is placed on the module on the side with the safety valve.
- the module cover hood has a flat cover plate whose width and length correspond to the dimensions of the module.
- the cover plate can be adapted to the three-dimensional geometry of the bearing surface on the module, for example to compensate for unevenness on the bearing surface on the module.
- bursting cutouts are provided, which are through openings in the module cover.
- Gas can be discharged from the surface of the module with the safety valve or safety valves via these bursting cutouts escapes from the cell in the event of overheating of a cell and opening of the safety valve.
- the number and position of the bursting cutouts in a module cover depends on the number of battery cells in a battery module. In addition, it should be possible to discharge the gas escaping from the safety valve of the battery cell quickly with a short discharge path.
- Each safety valve should therefore expediently be assigned a bursting cutout in the module cover hood, which comes to lie above the safety valve or safety valves when the module cover hood is placed on the module.
- Circumferential shape and size of the bursting section should correspond to the dimensions of the safety valve or, preferably, be larger.
- the bursting cut-outs are sealed with a bursting disc that only opens when the temperature and pressure of the hot gas affect it.
- the bursting cutouts above the cells that are not propagated remain closed in order to avoid contamination with the electrically conductive particles from the hot gas in these areas and to prevent the hot gas discharged from the module from bypassing back into the module through additional open bursting cutouts.
- the bursting cutout should be as close as possible above the safety valve in order to keep the escape path of the gas from the battery cell to the bursting cutout as short as possible.
- a dent or lowering can be provided in the area of the cover plate of the module cover hood, so that this lowered area comes to lie just above the safety valve.
- the module cover hood consists of a high-temperature-resistant material so that the hot gas can be safely discharged without the module cover hood itself catching fire or becoming deformed due to thermal effects.
- the module cover hood expediently has a temperature resistance of up to at least 1400 °C.
- the material for the module cover itself should not be electrically conductive.
- the module cover hood is obtained from a layered structure made of layers of fiber composite material. High-temperature-resistant fibers are used for the layers of fiber composite material.
- mineral fibers can be used, such as basalt fibers, glass fibers, silicate fibers and oxide ceramic fibers.
- the fibers can be in the form of a fabric such as a woven fabric or scrim, where the fabric itself can be made from rovings or yarns made from these fibers.
- the fiber flow is preferably bidirectional, e.g. in particular 0790°, but the fiber flow can vary as required, e.g. also be multidirectional, such as 0790745° etc.
- the plastics used as matrix material also have high temperature resistance.
- silicone resins in particular silicone resins with a high SiO content, in particular an SiO content of 50 to 90%, and particularly preferably 75% and higher.
- Silicone resins with an SiO content of at least 80% have proven to be particularly suitable.
- Difunctional and/or trifunctional polysiloxanes can be used as the silicone resin, preferably with methyl and/or phenyl substituents.
- SILRES® MK a trademark marketed by Wacker.
- the total thickness of the module cover hood should be as small as possible with regard to the desired space saving, preferably the total thickness should not exceed 1.5 mm. A thickness of 1 mm or less is preferred in order to take account of the desired compact, space-saving design of battery arrangements.
- the individual layers of the module cover can have different fibers and/or different fiber orientations.
- a layered structure can consist of one or two cover layers made of a first fiber composite material with one or more intermediate layers made of a second fiber composite material, depending on requirements.
- the layers of different fiber composite materials can be arranged alternately.
- each layer should be as thick as necessary but as thin as possible.
- a fiber composite material can also be used as the material for the bursting disk.
- suitable fibers are glass fiber or fibers made of plastic fabric, for example made of aramid, polyphenylene ether (PPE) and polypropylene (PP), and an epoxy resin as a matrix, for example based on bisphenol A.
- plastic fabric for example made of aramid, polyphenylene ether (PPE) and polypropylene (PP), and an epoxy resin as a matrix, for example based on bisphenol A.
- the module cover according to the invention with integrated gas discharge can delay the occurrence of flames and sparks outside a battery module for a period of at least 5 minutes and in particular at least 7.5 minutes and longer.
- the module cover hood according to the invention has excellent three-dimensional formability during production, so that a desired shape can be obtained precisely and without great effort.
- It can be three-dimensionally contoured in order to adapt the cover plate and/or edges to the surface structures of the bearing surfaces on the batteries.
- Figure 1 shows an embodiment of a module cover according to the invention with integrated gas discharge, the module cover being arranged over a battery module made of prismatic battery cells,
- FIG. 2 shows a plan view of a module cover according to the invention
- Figure 3 is a view from below of the module cover according to Figure 2.
- FIG. 1 shows the module cover 1 according to the invention with bursting cutouts 2 on a battery module 3 made up of a large number of prismatic battery cells 4 in an exploded view.

- a downward-pointing edge 9 is provided along the longitudinal sides of the cover plate 8 in order to be able to hold the module cover hood 1 securely on the module 3 .
- the cover plate 8 rests on the contacts 5 as the highest elevation on this side of the battery module 3, and the edges 9 rest on the side surfaces.
- the area of the cover plate 8 with the bursting cutouts 2 can be lowered in order to keep the distance between the bursting cutout 2 with the safety valve 6 as small as possible and the escape path of the gas as short as possible.
- the middle area of the cover plate 8 with the bursting cutouts 2 can be lowered in comparison to the adjacent areas of the cover plate 8 and form a channel that extends along the longitudinal axis.
- FIG. 1 shows the situation of the thermal runaway of the foremost battery cell 4 of the module 3, with the hot gas flow 7 emerging from the safety valve 6 being discharged directly and unhindered through the bursting cutout 2 above it from the area of the battery module 3.
- the bursting cutouts 2 are sufficiently large, so that the hot gas stream 7 flowing out of the underlying safety valve 6 can be discharged from the module 3 quickly and unhindered.
- the bursting cutouts 2 are approximately twice as large in length and width as the safety valve 6.
- exiting hot gas stream 7, enriched with electrically conductive particles is quickly discharged from the module 3 in order to avoid contact with neighboring electrically conductive components and thus a possible short circuit, which can lead to the thermal runaway spreading to neighboring cells.

- FIG. 1 shows the use of the module cover 1 for battery modules 3 made of prismatic battery cells 4 in which the safety valve 6 is provided between the electrical contacts 5 to illustrate the present inventive module cover 1 with integrated gas discharge.
- module cover hood 1 can also be used without further ado for battery cell designs that deviate from it, for example in which the safety valve 6 is in a different position than between the contacts 5, for example on a different surface of the battery housing.
- the module cover hood 1 according to the invention can also easily be adapted to construction-related irregularities such as differences in height or the like on the contact surfaces on the battery cells or modules.
