Description

Technical Field

[0001] The present invention relates to the technical field of battery modules, and in particular to an energy storage battery module. Background Art

[0002] With the extensive application of batteries in production and life, battery safety has become a topic of concern. If the heat is not dissipated in time during the battery charging and discharging process, it may lead to reduced battery performance and shortened lifespan, or even cause battery breakage, smoking, and explosion. Currently, the thermal management of batteries mainly adopts air cooling, which has low efficiency; or liquid cooling is carried out by coil cooling at the bottom of the battery pack, which has a long heat dissipation path and leads to low heat dissipation efficiency.

[0003] The existing energy storage battery modules cannot provide a constant temperature environment and protection for safe operation, and are prone to burst or explode directly in abnormal situations. The safety and high-voltage resistance of the battery modules are poor. They cannot provide abnormal warnings when sudden abnormalities occur inside the battery modules, and cannot remind users in advance to escape danger urgently, and cannot delay the process of battery module mutations. The overall explosion-proof strength of the battery modules is low, and they cannot isolate open flames and high temperatures. The safety and explosion-proof performance are poor, and the main shell is prone to moisture or short circuits. The autonomous heat dissipation and cooling function is weak, and it cannot effectively discharge the suddenly increased high-temperature air pressure inside. Summary of the invention

The ejected and diffused colored smoke bombs are used to remind the user in advance that an abnormality has occurred inside the battery module, thereby helping the user to escape from danger urgently.

[0012] Preferably, a baffle plate is fixedly connected to the edge of the arched flat tube away from the heat inlet to ensure that the hot air flow is smoothly introduced into the inner cavity of the arched flat tube, and the other end is fixedly connected to the inner wall of the integrated shell. An inlet is provided at one end of the arched flat tube close to the heat inlet, which is used to guide the hot air flow entering the inner side of the integrated shell through the heat inlet to the inner side of the arched flat tube, wherein the arched flat tube is connected to the inner cavity of the guide tube through the double wrist joints, the bending tube and the long expansion tube.

[0013] Preferably, the heat dissipation assembly includes a bell mouth that penetrates and is opened on the short wall plate of the main shell, and the large opening faces the outside, and the small opening faces the inside of the main shell. A baffle is fixedly connected to the inner wall of the large opening of the bell mouth facing the outside, and is symmetrically arranged in the bell mouth. A copper cold conduction plate is installed on the side of the baffle plate close to the heat conduction assembly. The whole is thickened to play an explosion-proof and damage-proof role, and is limitedly installed in the short wall plate of the main shell, and is limitedly blocked on the inside of the bell mouth by two baffle plates that are symmetrically arranged in the upper and lower parts, and is also limitedly installed between the baffle plate and the small opening;

[0014] Among them, the working state of the copper cold conduction plate when evacuating the heat inside the main shell is, that is, the initial state: it is installed obliquely between the baffle plate and the small opening with the diagonal axis as the axis. At this time, a heat dissipation gap is left between the copper cold conduction plate and the small opening, so that the hot air flow can pass through the gap between the copper cold conduction plate and the small opening, as well as the guiding effect of the large opening, to evacuate the hot air flow to the outside.

[0015] Preferably, memory alloy rods are fixedly connected to the middle parts of both ends of the copper cold conduction plate, and are straightened by heat, and a plate receiving cavity is opened at the position where the copper cold conduction plate is installed corresponding to the position in the short wall plate of the main shell, so that the copper cold conduction plate can be quickly pulled back into the plate receiving cavity under the straightening effect of the memory alloy rod after being heated, and a falling gate plate is installed in the short wall plate of the main shell, and the bottom side is blocked by the top edge of the copper cold conduction plate inclined with the diagonal axis as the axis, thereby blocking the hot air flow from diagonally diagonally diffusing to the outside.

[0016] Preferably, a one-way filter membrane is fixedly connected to the middle of the two long sides of the copper cold conduction plate to block external water vapor, and one end of the one-way filter membrane away from the copper cold conduction plate is fixedly connected to the middle of the top wall of the plate receiving cavity, and heat collecting grooves are opened at equal intervals on the inner side of the short wall plate of the main shell and are located on the side of the small opening, so that the battery can operate normally within a safe temperature range.

[0017] Preferably, a Z-shaped groove is penetrated through the short wall plate of the main shell and is located directly below the bell mouth, and provides an outward passage together with the breaking plate and the near baffle plate at the air outlet of the integrated shell, further providing a buffering and deceleration effect, wherein the outlet end of the Z-shaped groove penetrates the outer side surface of the short wall plate of the main shell, and a breaking seal plate is embedded on the inner side of the outlet end of the Z-shaped groove, which is used to block dust and water vapor and prevent them from entering the inner side of the main shell.

[0018] Preferably, two fans are symmetrically installed on the top of the porous heat collecting plate, and the bottom air outlet of the fan is connected to a downpipe to transport the heat collected in the porous heat collecting plate downward. A block is installed at the front end of the guide pipe that passes through the short wall plate of the main shell to seal the outlet of the guide pipe to prevent the colored smoke bomb from being directly exposed to the outside air or accidentally falling. Guide bevel portions are provided at the corners between the short wall plate and the bottom plate on the inner side of the main shell to improve the overall explosion-proof strength of the main shell.

[0019] The present invention provides an energy storage battery module, which has the following beneficial effects:

[0020] First, the energy storage battery module temporarily blocks the rushing speed of the high-pressure hot air flow by locating the near baffle plate in the forward direction of the breaker plate being impacted, and buffers and slows down the high-pressure hot air flow again. With the help of the colored smoke bomb filled in the guide tube, and under the condition that the blocking strength of the colored smoke bomb in the guide tube is lower than the bonding strength of the breaker plate and the long expansion tube, when the high-pressure hot air flow impacts the inner side of the long expansion tube, the colored smoke bomb will be pushed out from the outlet of the guide tube in advance, and the pushed out and diffused colored smoke bomb is used to remind the user in advance that an abnormality occurs inside the battery module, so as to help the user escape from danger urgently.

[0021] Second, the energy storage battery module can provide two buffer points through the double wrist joints when the hot air violently impacts the inside of the bending pipe, and buffer the hot air flow that is about to impact twice. The long expansion pipe can provide more release space for the high-pressure hot air flow that impacts the outlet of the bending pipe, thereby alleviating the local pressure of the hot air flow, reducing the speed at which the high-pressure hot air flow impacts outward, and delaying the process of battery module mutation.

[0022] 3. When the energy storage battery module is in normal working condition, part of the hot air flow entering the integrated shell is indirectly dissipated through heat transfer through the cooperation of the arched flat tube, double wrist joints, long expansion tube, breaking plate, near baffle, guide tube, baffle plate and breaking seal plate, so as to assist the heat dissipation and cooling of the interior of the main shell. At this time, when the battery module is in normal working condition, the heat dissipation assembly serves as the dominant component for the normal heat dissipation of the battery module.

[0023] Fourth, the energy storage battery module uses these six batteries as a supporting structure for mounting the porous heat collecting plate on the inner side of the main shell. On the one hand, the batteries located in the middle of the main shell are integrally bound and restrained, while the porous heat collecting plate can be located in the middle of the inner side of the main shell. The edge sealing uses a fan and a downpipe to transfer the heat collected at the top of the inner side of the main shell downward, that is, to the top of the heat conducting bottom plate. With the help of the rounded edge of the heat conducting bottom plate, part of the hot air flow is transported into the inner side of the integrated shell, and part of the hot air flow is guided to the inner side of the trumpet mouth by the heat collecting groove, the small opening and the copper cold conducting plate. Finally, the Z-groove and the trumpet mouth are used to transport, guide and diffuse the heat inside the main shell outward, so as to dissipate heat and cool the inner cavity of the main shell.

[0024] 5. The energy storage battery module is constructed by embedding the heat conduction assembly between the limit block and the heat conduction base plate, and embedding the three together on the base plate inside the main shell, and then stacking the mounting frame as a whole on the top of the heat conduction base plate, so that the bottom of the six-claw bottom cover fits on the heat conduction base plate, and then a corresponding number of batteries are correspondingly inserted into the frame through the battery jacks, and then the porous heat collecting plate is integrally embedded in the middle of the six batteries in the middle, and then the positive and negative poles of each battery are connected by wires, and a connector that can support power input and output is exposed from the top of the packaging cover, thereby realizing the charging and discharging functions of the battery module.

[0025] 6. The energy storage battery module is made of a glass-magnesium hollow color-coated steel composite plate as a whole, through the main shell and the packaging cover, so that the wires can be arranged inside the wall panels constituting the main shell and the packaging cover without destroying the integrity of the battery module shell structure. The glass-magnesium hollow color-coated steel composite plate has the advantages of good moisture-proof performance, dry and wet deformation rate, and thermal dimensional expansion rate, which are better than other products. Even in the hygroscopic state, the strength is very high and the composite plate will never be deformed. The overall explosion-proof strength of the battery module is greatly improved, and it can also isolate open flames and high temperatures to improve the safety and explosion-proof performance of the battery model, as well as the self-protection performance of isolating open flames.

[0026] 7. The energy storage battery module utilizes the Z-shaped groove to guide the corresponding breaking plate and the near baffle at the air outlet of the integrated shell, provides a passage for the breaking plate and the near baffle to be transported outward, and can utilize the Z-shaped groove to further provide a buffering and deceleration effect for the breaking plate and the near baffle when they are impacted to the outside by the high-pressure airflow, and utilizes the breaking sealing plate embedded in the inner side of the outlet end of the Z-shaped groove to block dust and water vapor to prevent them from entering the inner side of the main shell, so as to keep the main shell dry and not damp, so as to prevent the battery from being damp and unusable or short-circuited.

[0027] 8. For the energy storage battery module, when the battery module suddenly becomes abnormal and the temperature rises rapidly locally, or when individual batteries are naturally damaged, the heat absorption of the copper cold plate itself and the heat collection auxiliary effect of the heat collecting tank make the memory alloy rod quickly heated, and autonomously deform and rebound to the initial state, so as to quickly pull the copper cold plate to completely fit and seal in the receiving plate cavity, block the gap between the copper cold plate and the small opening, and prevent the high-pressure hot air flow from flowing out of the bell mouth. Instead, it is completely blocked by the copper cold plate that is completely enclosed in the receiving plate cavity, and all the high-pressure hot air flows are all in the heat-conducting bottom plate and the side inverted Under the guidance of the rounded corner, the colored smoke is transported into the inner side of the arched flat tube through the heat inlet and the inlet, and further transported to the inner side of the long expansion tube along the guidance of the double wrist joints and the bending tube, and combined with the air column originally on the inner side of the bending tube, the colored smoke bomb sealed on the inner side of the guide tube is ejected outward together with the plug. In this process, the colored smoke bomb is dispersed by the high-pressure hot air flow and mixed with the outside air to produce colored smoke. This form of spraying colored smoke from the side of the main shell is used to warn the user in advance that an abnormality has occurred inside the battery module, which plays a good visual warning role, reminding the user to quickly stay away from the battery module to avoid danger.

[0028] 9. For the energy storage battery module, after the colored smoke bomb is ejected, the breaker plate and the near baffle are continuously delayed and buffered, and the high-pressure hot air flow with a certain pressure is pressed open, and under the guidance of the Z-shaped groove corresponding to the near baffle, the breaker plate is finally impacted to release the pressure accumulated inside the main shell. In this process, through the heavy obstruction and buffering of the double wrist joints, the breaker plate, the near baffle, the Z-shaped groove and the breaker plate, the high-pressure hot air flow is relaxed in the process of being guided outward, on the one hand, the process of direct ejection of the high-pressure hot air flow is slowed down, and on the other hand, a safe warning time is provided for the colored smoke bomb ejection alarm, and a good elastic buffer release port is provided for the main shell that is about to be filled with high-pressure energy. With the help of the high-strength fire-resistant and high-temperature resistant materials used in the main shell and the packaging cover itself, the rapidly generated high-pressure energy can be effectively output stably from the Z-shaped groove vent, avoiding direct bursting or explosion when an abnormality occurs inside the battery module, providing users with sufficient response, and improving the safety and high-pressure resistance of the battery module.

[0029] 10. When the energy storage battery module is in normal use, the heat is collected near the small opening and diffused outward from the bell mouth, thereby assisting the internal heat dissipation and cooling of the main shell, so that the battery can work normally within a safe temperature range. Combined with the transfer and outward guidance of part of the heat by the heat conduction assembly, the heat at the bottom of the battery can be guided and diffused toward the two short wall plates through the heat conduction assembly and the heat dissipation assembly, thereby achieving two-way continuous cooling of the bottom of the battery module and maintaining the constant temperature inside the battery module. The downward guidance of the hot air flow by the porous heat collecting plate, fan, down pipe and heat conduction bottom plate can further accelerate the heat dissipation efficiency of the battery module itself, and ensure that the inner side of the main shell is always in a constant temperature state under normal use, thereby providing an effective constant temperature environment and guarantee for the safe operation of the battery module.

[0048] Among them, by using these six batteries 10 as a supporting structure for mounting the porous heat collecting plate 7 on the inner side of the main shell 1, on the one hand, the batteries located in the middle of the main shell 1 are bound and restrained as a whole, so that the porous heat collecting plate 7 can be located in the middle of the inner side of the main shell 1, and the edge sealing is used with the help of a fan 8 and a downpipe 9 to transport the heat collected at the top of the inner side of the main shell 1 downward, that is, to the top of the heat conducting bottom plate 4, and with the help of the rounded edge of the heat conducting bottom plate 4, part of the hot air flow is transported into the inner side of the integrated shell 51, and part of it is guided to the inner side of the trumpet mouth 61 through the heat collecting groove 67, the small opening and the copper cold conducting plate 63, and finally the Z-groove 68 and the trumpet mouth 61 are used to transport, guide and diffuse the heat inside the main shell 1 outward, so as to dissipate heat and cool the inner cavity of the main shell 1.

[0049] Among them, under the normal working state of the battery module, part of the hot air flow entering the integrated shell 51 is indirectly dissipated through heat transfer through the arched flat tube 53, the double wrist joint part 55, the long expansion tube 56, the breaking plate 57, the near baffle plate 58, the guide tube 59, the baffle plate 510 and the breaking plate 69, to assist the heat dissipation and cooling of the interior of the main shell 1. At this time, under the normal working state of the battery module, the heat dissipation assembly 6 serves as the dominant component for the normal heat dissipation of the battery module.

[0050] The second embodiment is based on the first embodiment.

[0052] A near baffle 58 is fixedly connected to the inner side of the integrated shell 51 and is located in the forward direction of the breaker plate 57 being impacted, and is used to temporarily block the rushing speed of the high-pressure hot air flow and buffer and slow down the high-pressure hot air flow again. A guide tube 59 is fixedly connected to the side of the end of the long expansion tube 56 away from the bending tube 54, and the inside is filled with a colored smoke bomb, and the blocking strength of the colored smoke bomb in the guide tube 59 is lower than the bonding strength of the breaker plate 57 and the long expansion tube 56, so that when the high-pressure hot air flow impacts the inside of the long expansion tube 56, the colored smoke bomb will be pushed out from the outlet of the guide tube 59 in advance, and the pushed out and diffused colored smoke bomb is used to remind the user in advance that there is an abnormality inside the battery module, so as to help the user escape from danger urgently. A baffle plate 510 is fixedly connected to the edge of the arched flat tube 53 away from the heat inlet 52, which strengthens the connection strength between the arched flat tube 53 and the integrated shell 51 while preventing the hot air flow from directly entering the middle of the inner cavity of the integrated shell 51 from both sides of the arched flat tube 53, ensuring that the hot air flow is smoothly introduced into the inner cavity of the arched flat tube 53, and the other end is fixedly connected to the inner wall of the integrated shell 51, and an inlet port 511 is provided at one end of the arched flat tube 53 close to the heat inlet 52, which is used to guide the hot air flow entering the inner side of the integrated shell 51 through the heat inlet 52 to the inner side of the arched flat tube 53, wherein the arched flat tube 53 is connected to the inner cavity of the guide tube 59 through the double wrist joint 55, the bending tube 54 and the long expansion tube 56.

[0053] During use, when the battery module suddenly becomes abnormal and the temperature rises rapidly locally, or when individual batteries 10 are naturally damaged, the heat absorption of the copper cold plate 63 and the heat collection auxiliary effect of the heat collecting groove 67 make the memory alloy rod 64 quickly heated, and autonomously deform and rebound to the initial state, so as to quickly pull the copper cold plate 63 to completely fit and seal in the receiving plate cavity, block the gap between the copper cold plate 63 and the small opening, and prevent the high-pressure hot air flow from flowing out of the bell mouth 61. Instead, it is completely blocked by the copper cold plate 63 that is completely enclosed in the receiving plate cavity, and all the high-pressure hot air flows are all directed to the heat-conducting bottom plate 4 and the rounded corners on the sides. The colored smoke is guided down and transported into the inner side of the arched flat tube 53 through the heat inlet 52 and the inlet 511, and further transported to the inner side of the long expansion tube 56 along the guidance of the double wrist joints 55 and the bending tube 54, and combined with the air column originally on the inner side of the bending tube 54, the colored smoke bomb blocked on the inner side of the guide tube 59 is ejected outward together with the plug 11. In this process, the colored smoke bomb is dispersed by the high-pressure hot air flow and mixed with the outside air to produce colored smoke. This form of spraying colored smoke from the side of the main shell 1 is used to warn the user in advance that an abnormality has occurred inside the battery module, which plays a good visual warning role, reminding the user to quickly stay away from the battery module to avoid danger. After the colored smoke bomb is sprayed out, the breaker plate 57 and the near baffle plate 58 are continuously delayed and buffered, and the high-pressure hot air flow with a certain pressure is pressed open, and under the guidance of the Z-shaped groove 68 corresponding to the near baffle plate 58, the sealing plate 69 is finally impacted to release the pressure accumulated inside the main shell 1. In this process, through the heavy obstruction and buffering of the double wrist joints 55, the breaker plate 57, the near baffle plate 58, the Z-shaped groove 68 and the sealing plate 69, the high-pressure hot air flow is relaxed in the process of being guided outward, which slows down the high-pressure hot air flow. The process of direct airflow ejection, on the one hand, provides a safety warning time for the colored smoke bomb ejection alarm, and provides a good elastic buffer release port for the main shell 1 that is about to be filled with high-pressure energy. With the help of the high-strength fire-resistant and high-temperature resistant materials used in the main shell 1 and the packaging cover 2, the rapidly generated high-pressure energy can be effectively output stably from the Z-groove 68 vent, avoiding direct bursting or explosion when an abnormality occurs inside the battery module, providing users with sufficient response realization, and improving the safety and high-pressure resistance of the battery module.

[0054] The third embodiment, based on the first and second embodiments, please refer to Figures 1 to 8As shown, the heat dissipation assembly 6 includes a bell mouth 61 that penetrates and is opened on the short wall plate of the main shell 1, and the large opening faces the outside, and the small opening faces the inside of the main shell 1. A baffle plate 62 is fixedly connected to the inner wall of the large opening of the bell mouth 61 facing the outside, and is symmetrically arranged in the bell mouth 61. A copper cold conduction plate 63 is installed on the side of the baffle plate 62 close to the heat conduction assembly 5. The whole is thickened to play an explosion-proof and damage-proof role, and the limit is installed in the short wall plate of the main shell 1 and is symmetrically arranged in the upper and lower parts. The plate 62 is limited and blocked on the inner side of the bell mouth 61, and is also limited and installed between the baffle plate 62 and the small opening; wherein, the working state of the copper cold conduction plate 63 when evacuating the heat inside the main shell 1 is, that is, the initial state: it is installed obliquely between the baffle plate 62 and the small opening with the diagonal as the axis. At this time, a heat dissipation gap is left between the copper cold conduction plate 63 and the small opening, so that the hot air flow can pass through the gap between the copper cold conduction plate 63 and the small opening, as well as the guiding effect of the large opening, to evacuate the hot air flow to the outside.

[0055] The middle parts of both ends of the copper cold conducting plate 63 are fixedly connected with memory alloy rods 64, which are stretched straight by heat, and a plate-receiving cavity is provided at the position where the copper cold conducting plate 63 is installed in the short wall plate of the main shell 1. Under the straightening effect of the memory alloy rods 64 after being heated, the copper cold conducting plate 63 can be quickly pulled back into the plate-receiving cavity. A drop gate 65 is installed in the short wall plate of the main shell 1, and the bottom side is blocked by the top edge of the copper cold conducting plate 63 inclined with the diagonal axis as the axis. After the copper cold-conducting plate 63 is pulled back to the plate-collecting cavity by the memory alloy rod 64, it can fall down quickly. In combination with the baffle plate 62, the copper cold-conducting plate 63 is positively clamped between the baffle plate 62 and the falling gate plate 65 to block the hot air flow from the bell mouth 61 to the outside. The middle parts of the two long edges of the copper cold-conducting plate 63 are fixedly connected with a one-way filter membrane 66 for blocking the external water vapor, and the end of the one-way filter membrane 66 away from the copper cold-conducting plate 63 is fixedly connected to the top wall of the plate-collecting cavity. The short wall plate of the main shell 1 is evenly spaced with heat collecting grooves 67 on the inner side, and is located on the side of the small opening, so as to collect heat near the small opening when the battery module is in normal use, and diffuse it outward from the bell mouth 61, so as to assist the internal heat dissipation and cooling of the main shell 1, so that the battery 10 can work normally within a safe temperature range. Combined with the transfer and outward guidance of part of the heat by the heat conducting assembly 5, the heat at the bottom of the battery 10 can be guided and diffused to the two short wall plate sides through the heat conducting assembly 5 and the heat dissipation assembly 6, so as to achieve two-way continuous cooling of the bottom of the battery module, maintain the constant temperature inside the battery module, and with the help of the porous heat collecting plate 7, the fan 8, the down pipe 9 and the heat conducting bottom plate 4 to guide the hot air flow downward, so as to further accelerate the heat dissipation efficiency of the battery module itself, and can ensure that the inner side of the main shell 1 is always in a constant temperature state under normal use, so as to provide an effective constant temperature environment and guarantee for the safe operation of the battery module.
