Description

[0001] A PROTECTIVE CASE CONFIGURATION

[0002] Technical Field

[0003] The invention relates to a case that prevents damage to the driver or the individuals inside and outside in adverse and dangerous situations such as accidents, fire and explosions that may occur in energy storage devices such as batteries and cells.

[0004] State of the Art

[0005] In the present art, adverse and dangerous situations can occur in electric vehicle batteries as a result of complications due to internal and external factors. In more detail, thermal leaks can occur due to excessive wear, improper charging, over-discharging, over- temperature or mechanical damage of the battery cells. Overcharging or discharging of batteries leads to increased internal stresses and damage to the cells. This increases the risk of explosion and chemical reactions inside the battery getting out of control. Also, in the event of a short circuit between the cells in the battery, internal heating and excessive energy flow can occur. This causes the battery to overheat, burn or even explode. Batteries can also be damaged as a result of traffic accidents or damage to the exterior of the vehicle. Such damages cause the cells in the batteries to be compromised and the internal electrolytes to leak, posing a risk of fire or explosion. It is necessary to protect the driver and the individuals inside or outside in dangerous and adverse situations such as accidents, fire and explosions that may occur with said batteries. At the same time, the batteries must be safely protected to avoid such dangerous situations.

[0006] In the present art, the batteries are not only used in electric vehicles, but also in many areas such as aviation, space, defense industry and fire brigades. For example, it is necessary to protect the internal systems and electrical components of said batteries against adverse and dangerous situations that may occur during logistics.

[0007] There is a need to develop new battery cases to overcome the disadvantages of the state of the art and those mentioned above. Summary of the Invention

[0008] In order to eliminate the above-mentioned disadvantages and to offer new advantages to the relevant technical field, the present invention relates to a case that prevents damage to the driver or the individuals inside and outside in adverse and dangerous situations such as accidents, fire and explosions that may occur in energy storage devices such as batteries and cells.

[0009] With the case according to the invention, the energy generated in dangerous situations such as fire and explosion that may occur in energy storage devices such as batteries and cells is trapped in the case. This prevents harmful factors such as heat, fire, force (explosion) and shrapnel that may occur from the inside to the outside. In addition, the case serves as a preventive barrier against various negative factors that can damage the device from the outside to the inside, such as crashing, hitting, explosion from the outside and fire contact from the outside.

[0010] The invention provides protection to the external environment, especially from the internal effects of electric vehicle batteries. It also protects the battery from external effects. By preventing heat transfer, the case according to the invention prevents shrapnel scattering and energy transfer, for example in the event of an explosion. At the same time, the layers thereof are made of stone wool and aluminum alloy material, preventing the battery from being damaged in dangerous situations such as fire and explosion. In summary, the invention is a battery protection case that completely encloses the battery to protect people and the environment from the damage caused by electric vehicle batteries to the environment and human beings, and to protect the battery from the environment.

[0011] The case according to the invention prevents thermal permeability and fire permeability with its resistance to fire and heat conditions by means of the first insulation layer and the second insulation layer thereof.

[0012] The case according to the invention prevents damage to the external environment by the battery and to the battery by the external environment through resilience and resistance against external and internal explosion, impact, and other energy and power transfers since the first layer, second layer, third layer and fourth layer are made of a metal alloy material, preferably an aluminum alloy material. The invention prevents malfunctions and problems that may occur within the device and against the device by means of enclosing and engaging in energy storage devices such as batteries and cells. It does not expose the effects of fire and explosion with the transfer prevention method and protects the device in case of external impact.

[0013] The sensors included in the case notify the driver and passengers with a warning about fire and similar situations that occur in the battery via a mobile application, wired or wireless communication methods, electrical, audio or WIFI methods in case of a temperature rise. Thus, possible accidents are prevented.

[0014] The case according to the invention is used in the battery industry and especially in electric vehicle battery systems. In addition, it is not only used in the automotive industry, but can also be used in many areas such as aviation industry, space industry, defense industry and fire brigades. Thus, the invention eliminates the need for a separate configuration for each application and provides an alternative for use in many areas. In addition, the case can be integrated into each part with an electric battery system outside the vehicle to protect the battery systems and electrical components during transportation and logistics activities of said parts. In summary, the case according to the invention is a precautionary and protective mechanism.

[0053] The case (100) according to the invention comprises at least one sensor. Said sensors are positioned inside the case (100). In an embodiment of the invention, the sensors are positioned in the second layer (3) and / or the third layer (5), but the embodiment is not limited thereto. Due to the case (100) that prevents the transfer of energy to the outside, the sensor notifies parties such as the driver, passenger, the user of the energy storage unit or the owner of the vehicle of situations such as fire or explosion that will not be noticed in the external factor. Furthermore, the sensor notifies the driver, passengers or users of any malfunctions that may occur in the case (100), e.g. for the battery. In a preferred embodiment of the invention, the sensors are at least one temperature sensor and / or at least one humidity sensor and / or at least one pressure sensor, but the embodiment is not limited thereto. With the sensors in the case (100), the drivers, passengers or users are notified with a warning via a mobile application, wired or wireless communication methods about situations such as fire, etc. that occur in the energy storage devices such as batteries and cells. The warning referred to herein is communicated in the form of electrical, audio, GSM waves, WIFI, bluetooth or internet notifications. Thus, possible accidents are prevented.

[0054] The case (100) according to the invention comprises at least one removable chamber (10). At least one desiccants material is placed in said removable chamber (10) to absorb the moisture that may be formed in the case (100), thereby preventing the pressure that may be generated in the case (100). Said desiccants are dry silica, silica gel, bentonite clay, calcium chloride, calcium sulphate or activated alumina, but the embodiment is not limited thereto. In an embodiment of the invention, the removable chamber (10) has a form that can be opened and closed manually by hand, but the embodiment is not limited thereto.

[0055] The case (100) according to the invention comprises at least one connection slot (9). Said connection slot (9) allows the energy storage devices such as batteries and cells in the case (100) to be inserted into the sockets. The connection slot (9) is positioned on the first layer (1 ), the first insulation layer (2) and the second layer (3). In an embodiment of the invention, said connection slot (9) is positioned on the layers with at least one part (not shown in the figures). Said part is welded to the first insulation layer (2) and positioned to be embedded in said layer. Furthermore, the part is positioned to be embedded in the face of the first insulation layer (2) facing the second layer (3). The connection slot (9) thus acts as a capsule. The connection slot (9) comprises at least one protrusion (9.1 ). Said protrusion (9.1 ) ensures the sealing of the connection slot (9), which is the energy slot. In an embodiment of the invention, the connection slot (9) has an “H”-form. With said “H” form, the power sources of the vehicle batteries are integrated into the vehicle engines. In another embodiment of the invention, there are provided two connection slots (9), but the embodiment is not limited thereto.

[0056] In the invention, the protective part (8) prevents the passage of shrapnel or fire (flame) to the case (100) in cases such as fire or explosion that may occur in the external environment. It also ensures protection of the edges of the layers and sealing of the case (100). In an embodiment of the invention, the protective part (8) is at least one strip sealer. In another embodiment of the invention, the protective part (8) has a “U”-form, but the embodiment is not limited thereto. The protective part (8) is positioned on each edge of the first layer (1 ), the first insulation layer (2), the second layer (3), the third layer (5), the second insulation layer (6) and the fourth layer (7), i.e. each layer. Said protective part (8) is made of a metal material, but the embodiment is not limited thereto. In another embodiment of the invention, the protective part (8) is made of metal alloy or metal- nonmetal alloy materials. In another embodiment of the invention, the protective part (8) is made of an aluminium material, steel material, iron material, titanium material, stone wool (rock wool) material or turbo blanket (thermal insulation blanket) material. The protective part (8) helps to mount all layers to each other. Said protective part (8) comprises at least one hole. Said holes allow the case (100) to be mounted with connecting elements such as bolts, screws, nuts or shafts, so that the case (100) remains in a secured form.

[0057] In an embodiment of the invention, the protective part (8) of the case (100) according to the invention is positioned on at least one edge of each layer. In another preferred embodiment of the invention, it is positioned on all edges of a layer. For example, it is positioned on all four sides of the first layer (1 ).

[0058] The case (100) completely encloses the battery or energy storage devices and allows the insertion and removal of the input and output sockets to and from the device, which have an energy connection with the device.

[0059] The material types of the components contained in the case (100) according to the invention may vary according to the sector, industry and requirements. In the fire simulations performed for the invention, the case (100) transferred heat from a temperature of 1000°Cto the outermost layer such that the temperature was 50°C in 3 minutes. In said simulations, the protective part (8) located on the sides of the case (100) ensures that the parts of the case (100) are held together. This shows that the effect to the external environment in cases of explosion or fire and from the external environment to the internal environment in case of impacts has been isolated and the damage to be caused has been prevented. The aluminium alloy in the case (100) ensures precautions and measures against explosion situations with its resilience and metal structure. In the explosion simulations, a 20 kg TNT was detonated inside the case (100) and in the external environment, the case (100) stretched but did not disintegrate, and only a 25 cm high stretch occurred. In addition, heat transfer is prevented due to the fact that the layers of the case (100) are made of rock wool.

[0060] In the impact simulations performed for the invention, an object made of steel with a mass of 67 kg was released from a height of 10 m and impacted the case (100) at a speed of 36 km per hour. No fractures or cracks were observed in the case (100) as a result of the impact. In addition, a car chassis impacted the case (100) at a speed of 60 km / h and there were no consequences that would cause the case (100) to lose its function. Also, no cracking has occurred.
