Description

Technical Field

[0001] This invention relates to the field of new energy storage, and more specifically to a high-safety lithium-ion battery energy storage product with thermal management function based on new energy. Background Technology

[0002] Electricity has a significant impact on national industry and people's lives, and energy security is one of the key issues that the country needs to consider when formulating policies.

[0003] With the rapid development of new energy power generation, electric vehicles, and smart grid technologies, lithium-ion batteries have become the core carrier in the field of electrochemical energy storage due to their advantages such as high energy density and long cycle life. However, existing lithium battery energy storage systems still face significant technical bottlenecks in terms of safety: First, traditional battery module structure designs lack effective mechanisms to prevent the propagation of thermal runaway, and thermal runaway of individual cells can easily trigger chain reactions, leading to system-level safety accidents; second, the flammability of existing electrolyte systems and the insufficient thermal stability of electrode materials pose a risk of fire and explosion under conditions of overcharging, short circuits, or mechanical abuse; furthermore, the battery management system (BMS) module lacks sufficient accuracy in predicting early faults, making it difficult to implement effective intervention before the thermal runaway critical point. Although the industry has improved safety through enhanced thermal management and optimized separator coatings, the contradiction between protective measures and energy density remains, and the safety redundancy design under complex operating conditions significantly increases system costs. For lithium battery energy storage products that store a large amount of energy, when thermal runaway occurs and fire breaks out, the effect of using common fire extinguishers is limited. If fire water is used to extinguish the fire, it requires personnel with professional knowledge to operate. At the same time, these types of energy storage products often have high voltage, and firefighters are at risk of electric shock when sprayed with water.

[0004] Lithium iron phosphate (LFP) cells are widely used in lithium-ion batteries due to their low cost, long lifespan, and good safety. However, their disadvantages are also significant, namely poor low-temperature performance. For example, most LFP cells release about 70% of their energy at 0°C compared to room temperature, and only about 50% at -10°C. Many LFP cells cannot be charged below 0°C or discharged below -10°C, severely limiting their application range and hindering their expansion into the low-temperature climate market. Temperatures below 0°C exist throughout Russia and Canada, as well as in most parts of China, the United States, and Europe.

[0005] Currently, some lithium-ion battery energy storage products use air cooling technology to dissipate heat generated by the battery cells and internal inverters. A fan draws outside air over the surfaces of these components and exhausts it outside the product. However, when outside air enters the product, it carries dust inside. Over time, this dust accumulation affects the product's normal operation. While dust filters at the air inlet reduce dust entry, they also reduce airflow, impacting heat dissipation. Regular filter replacement is necessary, but this doesn't completely prevent dust from entering the product. Using an air conditioning system, with a sealed casing and internal air circulation within the energy storage product, and the outdoor unit located outside, solves both heat dissipation and sealing issues. However, this method has significant drawbacks. First, the overall cost of the air conditioning system is high, increasing product costs. Second, the system requires significant power to operate, consuming more electricity and increasing operating costs.

[0006] Therefore, developing a lithium-ion battery energy storage product that combines low-temperature resistance, high safety, and low cost would be ideal for use in environments with low temperatures and would be beneficial for opening up new markets for large-scale energy storage. Summary of the Invention

[0007] To overcome the aforementioned deficiencies of existing technologies, this invention provides a high-safety lithium-ion battery energy storage product with thermal management capabilities based on new energy sources. To address the thermal management issues of lithium-ion battery energy storage products, when the lithium battery temperature is low, a fan drives a heating film to heat the gas, thus heating the lithium-ion battery. When the lithium battery temperature is high, the product's heat dissipation shell transfers internal heat to the outside. Whether heating the lithium battery or dissipating heat, the gas circulates within the product, preventing dust from the outside air from entering and affecting product performance. Furthermore, the cost is low during use. In the event of thermal runaway and fire, the hot gas will break through the protective film, allowing water to enter the product. The system will automatically extinguish the fire without the need for firefighters, providing timely and rapid fire suppression to prevent the fire from spreading to surrounding flammable materials and reducing loss of life and property. It also reduces the safety risks associated with overcharging during firefighting and minimizes the need for fire trucks and other social resources.

[0008] The technical solution of this invention is as follows:

[0009] A high-safety lithium-ion battery energy storage product with thermal management function based on new energy includes a heat dissipation shell assembly 1, a heat insulation shell 2, a module fixing frame 12, a movable heat insulation block assembly 19, a threaded guide rail 20, and a base plate 14.

[0010] The heat dissipation housing assembly 1 includes a heat dissipation housing 1a, a main door 1c, and a small door 1d. The top of the heat dissipation housing has two water storage areas: a primary water storage area 1aa and a secondary water storage area 1ab. The central area is the primary water storage area, which is surrounded by a primary water storage wall 1ad. This wall has multiple drainage holes 1ah on its side, arranged in two rows along the height, with multiple holes in each row. The top of the side wall has multiple notches 1aj. Outside the primary water storage area is the secondary water storage area, which is surrounded by a secondary water storage wall 1ak.

[0011] There is a small trough 1am on the inner side of the bottom of the water storage wall. When there is a small amount of water in the secondary water storage area, the small trough can be filled with water. In the secondary water storage wall, there are multiple gaps 1an at the top of the left side wall, right side wall and rear side wall, and multiple drainage holes 1ap at the bottom. These drainage holes are arranged in two rows in the height direction, and each row has multiple drainage holes. When the small trough is full of water, both rows of drainage holes can spray water outward. There is a blowout block 1aq on the outside of the drainage hole. The blowout block has a downward opening 1ar. When the water in the drainage hole 1ap is drained from the small trough 1am, if the water pressure is high, it will spray onto the blowout block and bounce back, flowing down along the side wall.

[0012] The main door 1c is installed on the outside of the door opening 1as and can be opened and closed. Above the door opening, there is a small hole on the front side of the heat dissipation shell. There are convex structures on the left and right sides of the main door. On the inside of the left convex 1au, there is a groove structure 1at. The inner wall of the groove has multiple small holes 1av. The groove structure contains a water-absorbing bag 17 and an oxygen-consuming bag 18. The water-absorbing bag contains calcium oxide. When there is water vapor inside the energy storage product, the water-absorbing bag will absorb it to prevent water vapor from affecting the performance of the energy storage product. The oxygen-consuming bag contains iron powder and sodium chloride. It is used to absorb oxygen inside the energy storage product. In a low-oxygen environment, even if thermal runaway occurs, the open flame and heat generated by the lithium-ion battery module will be much less than in ordinary air, which is beneficial to improving product safety. A small door 1d is installed on the outside of the convex 1as. When the small door is closed, water vapor will not be able to enter the product from the outside.

[0013] It also includes a fan 9, a fan mounting bracket 10, a lithium-ion battery module 11, and a module mounting bracket 12. The heat dissipation housing assembly contains a module mounting bracket 12, and multiple lithium-ion battery modules 11, a battery management system module 15, an inverter 16, and a fan mounting bracket 10 are fixed to the module mounting bracket. The fan 9 is fixed to the fan mounting bracket 10. The heat insulation housing 2 has a left wall, a right wall, a rear wall, and a top wall, wherein the rear wall has multiple ventilation holes.

[0014] The heat insulation shell 2 is arranged between the module fixing frame 12 and the heat dissipation shell 1a. Multiple first coil assemblies 7 are fixed to the heat insulation shell 2. Each coil assembly includes a permanent magnet 7a, a coil 7b, and a buffer cotton 7c. The coil is annular, with the permanent magnet fixed at its center. The buffer cotton is fixed to one side of the coil, which is the N pole of the permanent magnet, facing the heat dissipation shell. The coil has two power supply interfaces, one A and one B. When the positive power supply is connected to A and the negative power supply to B, the coil generates a magnetic field. One side of the buffer cotton is the N pole of the coil; when the negative power supply is connected to A... When B is connected to the positive terminal of the power supply, the coil generates a magnetic field. One side of the buffer cotton is the S pole of the coil. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet. Therefore, the buffer cotton side of the coil assembly exhibits S pole characteristics. Multiple threaded guide rails 20 pass through the holes of the movable heat insulation block assembly 19 and the heat insulation shell 2. One end is fixed to the module fixing bracket 12 by threads, and the other end is fixed to the inside of the heat dissipation shell 1a. The threaded guide rails serve to guide the movable heat insulation block assembly 19 and reinforce the heat dissipation shell. Water may be present on the outer side of the upper wall of the heat dissipation shell, which has a large mass. Support will help extend the life of the heat dissipation shell; the product has multiple movable heat insulation block assemblies 19, each of which includes a movable heat insulation block 19a and a permanent magnet 19b embedded in the movable heat insulation block, with the S pole of the permanent magnet facing the N pole of the permanent magnet in the first coil assembly 7; multiple second coil assemblies 8 are fixed to the inner wall of the heat dissipation shell, each coil assembly including a permanent magnet, a coil and cushioning cotton, the coil being annular with a permanent magnet fixed at its center, the N pole side of the permanent magnet in the second coil assembly being close to the inner side of the heat dissipation shell, and the cushioning cotton being fixed to the S pole side of the permanent magnet in the coil. In the second coil assembly, the S pole of the permanent magnet faces the N pole of the permanent magnet in the movable heat insulation block. The coil has two power line interfaces, one is the C interface and the other is the D interface. When the positive power supply is connected to C and the negative power supply is connected to D, the coil generates a magnetic field. One side of the buffer cotton is the N pole of the coil. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet. Therefore, the buffer cotton side of the coil assembly exhibits N pole characteristics. When the negative power supply is connected to C and the positive power supply is connected to D, the coil generates a magnetic field. One side of the buffer cotton is the S pole of the coil and its magnetic induction intensity is superimposed with that of the S pole of the permanent magnet.

[0015] Three air control plates 3 are arranged between the heat insulation shell and the heat dissipation shell assembly. They are all located on the rear wall of the heat insulation shell, with one side in close contact with the rear wall. One air control plate is in close contact with the line where the rear wall intersects with the upper wall, the second air control plate is in close contact with the line where the rear wall intersects with the left wall, and the third air control plate is in close contact with the line where the rear wall intersects with the right wall. Each of these air control plates has multiple ventilation holes with the same diameter but different center distances between the holes. This is to control the airflow after the gas exits from the rear wall of the heat insulation shell and to distribute the airflow through the upper, left, and right walls of the heat insulation shell. When the gas needs to dissipate heat, more flowing gas comes into contact with more inner surfaces of the heat dissipation shell, which is beneficial for heat dissipation.

[0016] When the internal temperature of the product is high and heat dissipation is required, the A port of the first coil assembly is connected to the positive terminal of the power supply, and the B port is connected to the negative terminal. The coil generates a magnetic field, with the side with the buffer cotton being the N pole. The permanent magnet inside the first coil assembly also has an N pole on this side, resulting in a superimposed and strengthened magnetic field. At this time, the N pole is directly facing the S pole of the permanent magnet of the movable heat insulation block, exhibiting a strong attraction. Simultaneously, the C port of the second coil assembly, fixed to the heat dissipation shell, is connected to the positive terminal, and the D port is connected to the negative terminal. The coil generates a magnetic field, with the side closer to the buffer cotton being the N pole of the coil. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet, so the side of the coil assembly with the buffer cotton exhibits N pole characteristics. This pole is directly facing the N pole of the permanent magnet of the movable heat insulation block, exerting a repulsive effect. Under the combined action of the attraction force of the first coil assembly and the repulsion force of the second coil assembly, the movable heat insulation block assembly moves to the side of the heat insulation shell. During the contact process, the buffer cotton acts as a buffer to prevent violent collisions and damage to the movable heat insulation block assembly. The fan drives hot gas to contact the inside of the heat dissipation shell, dissipating the heat through the heat dissipation shell to the outside of the product, thereby achieving heat dissipation for the product.

[0017] Each lithium-ion battery module in the lithium-ion battery module 11 has a heating film 1f at its bottom. When the internal temperature of the product is low and the gas needs to heat the lithium-ion battery module, the A interface of the first coil assembly is connected to the negative terminal of the power supply, and the B interface is connected to the positive terminal of the power supply. The coil generates a magnetic field, with the side with the buffer cotton being the S pole and the permanent magnet inside the first coil assembly being the N pole. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet, so the side of the coil assembly with the buffer cotton exhibits S pole characteristics. At this time, this pole is directly opposite the S pole of the permanent magnet of the moving heat insulation block, exerting a repulsive effect. At the same time, the C interface of the second coil assembly, which is fixed inside the heat dissipation shell, is connected to the negative terminal, and the D interface is connected to the positive terminal. The coil generates a magnetic field, with the side near the buffer cotton being the N pole. The S pole of the coil and the S pole of the permanent magnet inside the second coil assembly are superimposed. At this time, the S pole is directly facing the N pole of the permanent magnet of the movable heat insulation sheet, and there is a strong attraction. Under the combined action of the repulsive force of the first coil assembly and the attractive force of the second coil assembly, the movable heat insulation block assembly moves to the inside of the heat dissipation shell and combines with the shell heat insulation block 1b fixed inside the heat dissipation shell. This results in more than 95% of the area inside the heat dissipation shell being covered by heat insulation material, which can effectively prevent heat from being transferred to the heat dissipation shell and reduce heat loss from inside the product to outside the product. During the contact process, the buffer cotton plays a buffering role to avoid violent collisions and damage to the movable heat insulation block assembly. When the product needs to be heated, the heating film heats up, and the fan drives the gas to heat the surface of the lithium-ion battery module.

[0018] The top of the heat dissipation housing 1a has multiple explosion-proof holes 22, and an explosion-proof film 23 is tightly attached to the explosion-proof holes.

[0019] A breather valve 24 connected to the inside of the heat dissipation shell 1a is installed at the front of the heat dissipation shell 1a to play a role in pressure balance and is suitable for small air pressure fluctuations.

[0020] It also includes a base plate 14, which has a recessed structure, namely a water tank 14a, at the bottom of the product. A small groove 14b is provided on the base plate 14 between the heat dissipation component and the heat insulation shell. The bottom of the groove has an inclined angle and is located at the lowest point on the bottom inside the door. There are two electrode plates in this area, one of which is a positive electrode 14c and the other is a negative electrode 14d. When water soaks the two electrode plates, the positive and negative electrodes are connected to form a current, which flows through the alarm bell to emit an alarm sound. At the same time, the alarm information is transmitted to the mobile phone, and the mobile phone receives the alarm information.

[0021] It also includes a water supply pipe 4, a water pump 5, and a faucet assembly 6. The faucet assembly 6 is located outside the heat dissipation assembly and includes a float ball 6a, a valve body part 6b, a handle 6c, and a water outlet pipe 6d. The float ball 6a is a hollow spherical structure that can float on the water surface. The valve body part 6b has a hemispherical structure 6ba, which works similarly to a ball valve and can rotate around an axis. This hemispherical structure is embedded in the tap water outlet pipe 6d. By rotating it, the water outlet pipe can be controlled to produce water and the amount of water. The float ball 6a floats on the water in the pool and is connected to the valve body part 6b through the handle 6c. Depending on the water level, the faucet can be controlled to be turned on or off and the water flow rate can be controlled by controlling the rotation angle of the valve body part 6b. The water pump 5 is located outside the heat dissipation housing assembly and is connected to two water pipes. One end of one water pipe extends into the pool formed by the bottom plate, and the other water pipe, through the pressure of the water pump, transports water to the first-level water storage area on the upper wall.

[0022] Multiple water guide plates are fixed on the left, right, and rear sides of the heat dissipation shell 1a. These water guide plates are divided into multiple layers in the height direction, with multiple plates in each layer. Each water guide plate has multiple small holes 1ava at the bottom and small water-blocking walls 1avb on the outside. Long water-blocking plates 1ax are present at the intersection of the front, rear, left, and right sides of the heat dissipation shell 1a. These structures facilitate water to have more contact with the surface of the heat dissipation shell during the flow process, thus carrying away more heat. When the water flows to the water guide plates, it often tumbles and splashes, allowing the water to have more contact with the air, which is beneficial for heat dissipation. At the same time, the long water-blocking plates 1ax can prevent water from splashing away from the heat dissipation shell and hitting people.

[0023] The technical effects and advantages of this invention are as follows:

[0024] It has an excellent thermal management system. When the lithium battery temperature is low, the fan drives the heating film to heat the internal gas of the product, which in turn heats the lithium battery, while very little heat is transferred to the outside of the product. When the internal temperature of the product is high, it can transfer heat to the outside of the product, ensuring normal use of the product.

[0025] Dust will not get inside the product, protecting the internal components, especially electronic components, thereby extending the product's lifespan.

[0026] If the product overheats abnormally, it will issue an alarm and prompt for handling according to different situations. Even if a thermal runaway fire occurs, the system can automatically extinguish the fire, reducing the likelihood of surrounding items catching fire due to thermal runaway of the product, minimizing losses and casualties.

[0027] When in operation, there is no need to use a high-power air conditioning system, thus reducing operating costs. Attached Figure Description

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0049] A high-safety lithium-ion battery energy storage product with thermal management function based on new energy includes a heat dissipation shell assembly 1, a heat insulation shell 2, a module fixing frame 12, a movable heat insulation block assembly 19, a threaded guide rail 20, and a base plate 14.

[0050] The heat dissipation housing assembly 1 includes a heat dissipation housing 1a, a main door 1c, and a small door 1d. The top of the heat dissipation housing has two water storage areas: a primary water storage area 1aa and a secondary water storage area 1ab. The central area is the primary water storage area, which is surrounded by a primary water storage wall 1ad. This wall has multiple drainage holes 1ah on its side, arranged in two rows along the height, with multiple holes in each row. The top of the side wall has multiple notches 1aj. Outside the primary water storage area is the secondary water storage area, which is surrounded by a secondary water storage wall 1ak.

[0051] There is a small trough 1am on the inner side of the bottom of the water storage wall. When there is a small amount of water in the secondary water storage area, the small trough can be filled with water. In the secondary water storage wall, there are multiple gaps 1an at the top of the left side wall, right side wall and rear side wall, and multiple drainage holes 1ap at the bottom. These drainage holes are arranged in two rows in the height direction, and each row has multiple drainage holes. When the small trough is full of water, both rows of drainage holes can spray water outward. There is a blowout block 1aq on the outside of the drainage hole. The blowout block has a downward opening 1ar. When the water in the drainage hole 1ap is drained from the small trough 1am, if the water pressure is high, it will spray onto the blowout block and bounce back, flowing down along the side wall.

[0052] The main door 1c is installed on the outside of the door opening 1as and can be opened and closed. Above the door opening, there is a small hole on the front side of the heat dissipation shell. There are convex structures on the left and right sides of the main door. On the inside of the left convex 1au, there is a groove structure 1at. The inner wall of the groove has multiple small holes 1av. The groove structure contains a water-absorbing bag 17 and an oxygen-consuming bag 18. The water-absorbing bag contains calcium oxide. When there is water vapor inside the energy storage product, the water-absorbing bag will absorb it to prevent water vapor from affecting the performance of the energy storage product. The oxygen-consuming bag contains iron powder and sodium chloride. It is used to absorb oxygen inside the energy storage product. In a low-oxygen environment, even if thermal runaway occurs, the open flame and heat generated by the lithium-ion battery module will be much less than in ordinary air, which is beneficial to improving product safety. A small door 1d is installed on the outside of the convex 1as. When the small door is closed, water vapor will not be able to enter the product from the outside.

[0053] It also includes a fan 9, a fan mounting bracket 10, a lithium-ion battery module 11, and a module mounting bracket 12. The heat dissipation housing assembly contains a module mounting bracket 12, and multiple lithium-ion battery modules 11, a battery management system module 15, an inverter 16, and a fan mounting bracket 10 are fixed to the module mounting bracket. The fan 9 is fixed to the fan mounting bracket 10. The heat insulation housing 2 has a left wall, a right wall, a rear wall, and a top wall, wherein the rear wall has multiple ventilation holes.

[0054] The heat insulation housing 2 is arranged between the module fixing frame 12 and the heat dissipation housing 1a. Multiple first coil assemblies 7 are fixed to the heat insulation housing 2. Each coil assembly includes a permanent magnet 7a, a coil 7b, and a buffer cotton 7c. The coil is annular, with the permanent magnet fixed at its center. The buffer cotton is fixed to one side of the coil, which is the N pole of the permanent magnet, facing the heat dissipation housing. The coil has two power supply interfaces, one A and one B. When the positive power supply is connected to A and the negative power supply to B, the coil generates a magnetic field. The buffer cotton is the N pole of the coil, and when the negative power supply is connected to A... When B is connected to the positive terminal of the power supply, the coil generates a magnetic field. One side of the buffer cotton is the S pole of the coil. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet. Therefore, the buffer cotton side of the coil assembly exhibits S pole characteristics. Multiple threaded guide rails 20 pass through the holes of the movable heat insulation block assembly 19 and the heat insulation shell 2. One end is fixed to the module fixing bracket 12 by threads, and the other end is fixed to the inner side of the heat dissipation shell 1a. The threaded guide rails serve to guide the movable heat insulation block assembly 19 and reinforce the heat dissipation shell. There may be water on the outer side of the upper wall of the heat dissipation shell, which has a large mass. Support will help extend the life of the heat dissipation shell; the product has multiple movable heat insulation block assemblies 19, each of which includes a movable heat insulation block 19a and multiple permanent magnets 19b embedded in the movable heat insulation block, with the S pole of the permanent magnet facing the N pole of the permanent magnet in the first coil assembly 7; multiple second coil assemblies 8 are fixed to the inner wall of the heat dissipation shell, each coil assembly including a permanent magnet, a coil, and cushioning cotton, the coil being annular with a permanent magnet fixed at its center, the N pole side of the permanent magnet in the second coil assembly being close to the inner side of the heat dissipation shell, and the cushioning cotton being fixed to the S pole side of the permanent magnet in the coil. On the other side, the S pole of the permanent magnet in the second coil assembly faces the N pole of the permanent magnet in the movable heat insulation block. The coil has two power line interfaces, one is the C interface and the other is the D interface. When the positive power supply is connected to C and the negative power supply is connected to D, the coil generates a magnetic field. One side of the buffer cotton is the N pole of the coil. At this time, the magnetic induction intensity generated by the coil is greater than the magnetic induction intensity generated by the permanent magnet. Therefore, the buffer cotton side of the coil assembly exhibits N pole characteristics. When the negative power supply is connected to C and the positive power supply is connected to D, the coil generates a magnetic field. One side of the buffer cotton is the S pole of the coil and is superimposed with the magnetic induction intensity of the S pole of the permanent magnet.

[0055] Three air control plates 3 are arranged between the heat insulation shell and the heat dissipation shell assembly. They are all located on the rear wall of the heat insulation shell, with one side in close contact with the rear wall. One air control plate is in close contact with the line where the rear wall intersects with the upper wall, the second air control plate is in close contact with the line where the rear wall intersects with the left wall, and the third air control plate is in close contact with the line where the rear wall intersects with the right wall. Each of these air control plates has multiple ventilation holes with the same diameter but different center distances between the holes. This is to control the airflow after the gas exits from the rear wall of the heat insulation shell and to distribute the airflow through the upper, left, and right walls of the heat insulation shell. When the gas needs to dissipate heat, more flowing gas comes into contact with more inner surfaces of the heat dissipation shell, which is beneficial for heat dissipation.

[0056] When the internal temperature of the product is high and heat dissipation is required, the A port of the first coil assembly is connected to the positive terminal of the power supply, and the B port is connected to the negative terminal. The coil generates a magnetic field, with the side with the buffer cotton being the N pole. The permanent magnet inside the first coil assembly also has an N pole on this side, resulting in a superimposed and strengthened magnetic field. At this time, the N pole is directly facing the S pole of the permanent magnet of the movable heat insulation block, exhibiting a strong attraction. Simultaneously, the C port of the second coil assembly, fixed to the heat dissipation shell, is connected to the positive terminal, and the D port is connected to the negative terminal. The coil generates a magnetic field, with the side closer to the buffer cotton being the N pole of the coil. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet, so the side of the coil assembly with the buffer cotton exhibits N pole characteristics. This pole is directly facing the N pole of the permanent magnet of the movable heat insulation block, exerting a repulsive effect. Under the combined action of the attraction force of the first coil assembly and the repulsion force of the second coil assembly, the movable heat insulation block assembly moves to the side of the heat insulation shell. During the contact process, the buffer cotton acts as a buffer to prevent violent collisions and damage to the movable heat insulation block assembly. The fan drives hot gas to contact the inside of the heat dissipation shell, dissipating the heat through the heat dissipation shell to the outside of the product, thereby achieving heat dissipation for the product.

[0057] Each lithium-ion battery module 11 has a heating film 1f at its bottom. When the internal temperature of the product is low and gas is needed to heat the lithium-ion battery module, the A interface of the first coil assembly is connected to the negative terminal of the power supply, and the B interface is connected to the positive terminal of the power supply. The coil generates a magnetic field, with the side with the buffer cotton as the S pole. The permanent magnet inside the first coil assembly also has the N pole on this side. At this time, the magnetic induction intensity generated by the coil is greater than that generated by the permanent magnet. Therefore, the side of the coil assembly with the buffer cotton exhibits the characteristics of the S pole. This pole is directly opposite the S pole of the permanent magnet of the moving heat insulation block, resulting in a repulsive effect. At the same time, the C interface of the second coil assembly, which is fixed inside the heat dissipation shell, is connected to the negative terminal, and the D interface is connected to the positive terminal. The coil generates a magnetic field, which is close to the side with the buffer cotton. The first coil assembly has its S pole, and the permanent magnet inside the second coil assembly also has its S pole on the same side. The magnetic fields are superimposed, and the S pole is directly opposite the N pole of the permanent magnet in the movable heat insulation block, resulting in a strong attraction. Under the combined action of the repulsion from the first coil assembly and the attraction from the second coil assembly, the movable heat insulation block assembly moves to the inside of the heat dissipation shell and combines with the shell heat insulation block 1b fixed inside the heat dissipation shell. This forms a situation where over 95% of the area inside the heat dissipation shell is covered by heat insulation material, effectively preventing heat transfer to the heat dissipation shell and reducing heat loss from inside the product to the outside. During contact, the buffer cotton acts as a buffer to prevent violent collisions and damage to the movable heat insulation block assembly. When the product needs to be heated, the heating film heats up, and the fan drives gas to heat the surface of the lithium-ion battery module.

[0058] The top of the heat dissipation housing 1a has multiple explosion-proof holes 22, and an explosion-proof film 23 is tightly attached to the explosion-proof holes.

[0059] A breather valve 24 connected to the inside of the heat dissipation shell 1a is installed at the front of the heat dissipation shell 1a to play a role in pressure balance and is suitable for small air pressure fluctuations.

[0060] It also includes a base plate 14, which has a recessed structure, namely a water tank 14a, at the bottom of the product. A small groove 14b is provided on the base plate 14 between the heat dissipation component and the heat insulation shell. The bottom of the groove has an inclined angle and is located at the lowest point on the bottom inside the door. There are two electrode plates in this area, one of which is a positive electrode 14c and the other is a negative electrode 14d. When water soaks the two electrode plates, the positive and negative electrodes are connected to form a current, which flows through the alarm bell to emit an alarm sound. At the same time, the alarm information is transmitted to the mobile phone, and the mobile phone receives the alarm information.

[0061] It also includes a water supply pipe 4, a water pump 5, and a faucet assembly 6. The faucet assembly 6 is located outside the heat dissipation assembly and includes a float ball 6a, a valve body part 6b, a handle 6c, and a water outlet pipe 6d. The float ball 6a is a hollow spherical structure that can float on the water surface. The valve body part 6b has a hemispherical structure 6ba, which works similarly to a ball valve and can rotate around an axis. This hemispherical structure is embedded in the tap water outlet pipe 6d. By rotating it, the water outlet pipe can be controlled to produce water and the amount of water. The float ball 6a floats on the water in the pool and is connected to the valve body part 6b through the handle 6c. Depending on the water level, the faucet can be controlled to be turned on or off and the water flow rate can be controlled by controlling the rotation angle of the valve body part 6b. The water pump 5 is located outside the heat dissipation housing assembly and is connected to two water pipes. One end of one water pipe extends into the pool formed by the bottom plate, and the other water pipe, through the pressure of the water pump, transports water to the first-level water storage area on the upper wall.

[0062] Multiple water guide plates are fixed on the left, right, and rear sides of the heat dissipation shell 1a. These water guide plates are divided into multiple layers in the height direction, with multiple plates in each layer. Each water guide plate has multiple small holes 1ava at the bottom and small water-blocking walls 1avb on the outside. Long water-blocking plates 1ax are present at the intersection of the front, rear, left, and right sides of the heat dissipation shell 1a. These structures facilitate water to have more contact with the surface of the heat dissipation shell during the flow process, thus carrying away more heat. When the water flows to the water guide plates, it often tumbles and splashes, allowing the water to have more contact with the air, which is beneficial for heat dissipation. At the same time, the long water-blocking plates 1ax can prevent water from splashing away from the heat dissipation shell and hitting people. Example

[0063] When the lithium-ion battery module 11 and inverter inside the energy storage product generate heat and need to dissipate it, water from the tap flows into the pool formed by the recessed structure of the base plate 14. The water pump draws the water from the pool into the primary water storage area of ​​the heat dissipation shell. The side wall of the primary water storage area has multiple drainage holes arranged in two rows along the height, with multiple holes in each row. When the water in the primary water storage area overflows the lowest row of drainage holes, the water will flow from this row to the secondary water storage area. Because this row of drainage holes is relatively small and has limited drainage capacity, the water quickly rises to the higher row of drainage holes. The top of the primary water storage wall has multiple gaps. When one... After the water in the primary water storage area overflows the two rows of drain holes, it will continue to flow upwards to these gaps. The water then flows from these gaps to the secondary water storage area. Therefore, even if the upper wall of the heat dissipation casing is slightly tilted relative to the horizontal plane during installation, it ensures that water drains from each drain hole, allowing water to flow over most of the surface of the secondary water storage area. The flowing water carries away heat from the upper wall of the heat dissipation casing. Simultaneously, even when the primary water storage area is not full, good heat dissipation can still be achieved. The size of the primary water storage area and the height of the primary water storage wall can be adjusted based on specific test data to achieve optimal heat dissipation and water storage capacity, and to balance the entire primary water storage area... Compared to filling the entire area with water, this design also reduces the weight of the primary water storage area. After the water enters the secondary water storage area, it flows into a small trough located at the bottom inner side of the secondary water storage wall. This trough holds a very small amount of water. The secondary water storage wall has multiple notches at the top of the left, right, and rear walls, and multiple drainage holes at the bottom. These drainage holes are arranged in two rows along the height, with multiple holes in each row. The height of these drainage holes does not exceed the height of the main surface of the secondary water storage area. When the small trough is full of water, both rows of drainage holes can spray water outwards. This ensures that even if the upper wall of the heat dissipation casing is slightly tilted to the horizontal plane, as long as a small amount of water enters the secondary water storage area, water will be released. The system allows the small tank to be filled with water, and the drain holes at the bottom of the secondary water storage wall next to the small tank can drain water outwards. This means that the secondary water storage area does not necessarily need to store a lot of water, reducing the weight of water stored on the upper wall of the heat sink casing and reducing the design difficulty and cost of the heat sink casing. There is a blow-off block on the outside of the drain hole. The blow-off block has a downward opening. When water is drained from the small tank outwards from the drain hole, if the water force is strong, it will spray onto the blow-off block and bounce back, flowing down along the side wall. There is a door hole on the front of the heat sink casing. The large door is installed on the outside of the door hole and can be opened or closed. Above the door hole, there is a small front hole on the front side of the heat sink casing.The large hole has convex structures on both sides. Inside the left convex structure is a groove with multiple small holes on its inner wall. The water-absorbing bag and oxygen-consuming bag are placed inside this groove. The water-absorbing bag contains calcium oxide; when there is water vapor inside the energy storage product, the water-absorbing bag absorbs it, preventing water vapor from affecting the product's performance. The oxygen-consuming bag contains iron powder and sodium chloride; its main purpose is to absorb oxygen inside the energy storage product. This ensures that even if thermal runaway occurs in a low-oxygen environment, the lithium-ion battery module will generate significantly less open flame and heat than in normal air, improving product safety. A small door (1d) is installed on the outside of the convex structure; closing the door prevents water vapor from entering the product from the outside. Example

[0064] The internal fan must be on whenever the product is in normal charging or discharging mode. The product contains a temperature control unit that controls whether the heating film starts heating, whether the water pump is on, and whether the coil in the coil assembly is energized and the direction of the current. Depending on the temperature, the following situations apply:

[0065] When the internal temperature of the product is very low (e.g., below 0°C), the heating film activates, the water pump does not start, and the coil in coil assembly 1, fixed to the heat insulation shell, receives the negative power input at interface A and the positive power input at interface B. The coil generates a magnetic field, with the S pole on the side of the buffer cotton, while the permanent magnet on this side is the N pole. Because the magnetic induction intensity of the S pole generated by the coil is greater than that generated by the permanent magnet in coil assembly 1, this side exhibits S pole characteristics. In the permanent magnet of the moving heat insulation block assembly, the side facing coil assembly 1 is S, thus repelling the magnetic field generated by coil assembly 1. In coil assembly 2, which is close to the heat dissipation shell, the side of the permanent magnet near the buffer cotton is the S pole, facing the moving heat insulation block. The coil receives the negative power input at interface C and the positive power input at interface D. At this time, the coil near the buffer cotton is the S pole. At this time, the magnetic fields generated by the permanent magnet and the coil are in the same direction, and the magnetic induction intensity is superimposed. The side of the buffer cotton of coil assembly 2 facing the permanent magnet in the movable heat insulation block assembly is the N pole. Therefore, the force of coil assembly 1 pushes the movable heat insulation block assembly outward, and the force of coil assembly 2 attracts the movable heat insulation block assembly and makes it stick to the heat dissipation shell, combining with the shell heat insulation block 1b. More than 95% of the inner side of the heat dissipation shell is covered with heat insulation material (movable heat insulation block assembly and shell heat insulation block). It is difficult for the heat of the hot gas to dissipate to the outside of the product. The gas is driven by the fan to circulate and heat the lithium-ion battery module. After the movable heat insulation block sticks to the heat dissipation shell for a certain period of time (such as 10 seconds), the power supply to coil assembly 1 and coil assembly 2 is disconnected to save energy. The movable heat insulation block is attracted by the permanent magnet in coil assembly 2 and continues to work.

[0066] When the internal temperature of the product is moderate (e.g., 0℃ to 25℃), the heating film and water pump do not start. The coil in coil assembly 1, fixed to the heat insulation shell, receives the positive power input at interface A and the negative power input at interface B. The coil generates a magnetic field, with the N pole on the side of the buffer cotton, and the permanent magnet also having an N pole on that side. The magnetic fields generated by the permanent magnet and the coil are in the same direction, and their magnetic induction intensities are superimposed. In the permanent magnet of the moving heat insulation block assembly, the side facing coil assembly 1 is the S pole, thus attracting the moving heat insulation block with the magnetic force generated by coil assembly 1. In coil assembly 2, which is close to the heat dissipation shell, the side of the permanent magnet facing the buffer cotton is the S pole, facing the moving heat insulation block. The C interface of the coil receives the positive power input, and the D interface receives the negative power input. When the power supply is connected to the negative terminal, the coil is N-pole on the side closest to the buffer cotton. Since the magnetic induction intensity of the N-pole generated by the coil is greater than that generated by the permanent magnet in coil assembly 2, this side exhibits N-pole characteristics. At this time, the side of coil assembly 2 facing the permanent magnet in the movable heat insulation block is N-pole. Therefore, the presence of coil assembly 1 attracts the movable heat insulation block, and the presence of coil assembly 2 pushes the movable heat insulation block outward and presses it against the heat insulation shell. Gas flows in the air duct inside the movable heat insulation block and the heat dissipation shell. Since the inverter and lithium-ion battery module generate heat during the operation of the product, the heat dissipation shell will dissipate heat from the product. Therefore, the internal heat of the product is in a state of equilibrium.

[0067] When the internal temperature of the product is moderate (e.g., above 25℃), the heating film does not start, the water pump starts, and the coil assembly and the moving heat insulation block work in the same way as in case 2. At this time, the water pump starts, and the external flowing water carries away the heat from the heat dissipation shell, accelerating the product's heat dissipation.

[0068] When the explosion-proof valve is accidentally opened or fails, water will enter the product. The water will flow along the outside of the insulation shell, into the small groove on the bottom plate, and then flow along the inclined direction of the groove to the inside of the door, triggering an alarm. This indicates that the product has water ingress and needs to be dealt with as soon as possible. The situation requires careful inspection to find the root cause of the problem. Once repaired, the product may be able to be used normally.

[0069] When an energy storage product generates a large amount of heat within a very short time, and the gas breaks through the explosion-proof membrane and flows a large amount of water into the explosion-proof vent, this situation generally indicates that the lithium-ion battery is experiencing thermal runaway and will soon catch fire. The explosion-proof vent continuously flows into the heat dissipation shell. At this time, the water flowing from the upper wall to the bottom water tank will decrease, the water level in the tank will drop, and the floating parts on the valve body will also sink. This allows the water tap to be opened or the tap valve to be opened further, replenishing the water tank and providing a continuous flow of water into the energy storage product to extinguish the fire. The entire process is timely and rapid, requiring no human intervention, reducing the risk of nearby items catching fire due to thermal runaway, minimizing property damage, and reducing the possibility of injury or death to firefighters and ordinary personnel.

[0070] Under normal operating conditions, the heat generated by the lithium-ion battery modules and inverters on the module mounting bracket inside the product is driven by a fan fixed to the fan mounting bracket. The gas flows over the surfaces of the heat-generating components such as the battery pack and inverter, and flows through the holes on the rear side of the heat insulation shell to the space between the heat insulation shell and the heat dissipation shell. This allows the heat of the gas to be transferred to the heat dissipation shell and then flows back to the fan. The water flowing on the outer side of the heat dissipation shell carries away the heat from the heat dissipation shell. The water evaporates and cools down during the flow, thus continuously cooling the energy storage product.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Above the door opening, there is a small hole on the front side of the heat dissipation shell. There are convex structures on the left and right sides of the main door. On the inside of the left convex bulge (1au), there is a groove structure (1at). There are multiple small holes (1av) on the inner wall of the groove. The groove structure contains a water-absorbing bag (17) and an oxygen-consuming bag (18). The water-absorbing bag contains calcium oxide. When there is water vapor inside the energy storage product, the water-absorbing bag will absorb it to prevent water vapor from affecting the performance of the energy storage product.

Each of these air control plates has multiple ventilation holes with the same hole diameter but different center distances between the holes. This is to control the airflow after the gas comes out from the rear wall of the heat insulation shell and to reasonably distribute the airflow through the upper wall, left wall and right wall of the heat insulation shell. When the gas needs to dissipate heat, more flowing gas comes into contact with more inner surfaces of the heat dissipation shell, which is beneficial for heat dissipation.

When the lithium-ion battery module needs to be heated, the heating film heats up and the fan drives the gas to heat the lithium-ion battery module more evenly. At the same time, the movable heat insulation block assembly (19) moves to the side of the heat dissipation shell and is closely attached to the inside of the heat dissipation shell. It is combined with the shell heat insulation block (1b) attached to the inside of the heat dissipation shell (1a). This forms a heat insulation material covering more than 95% of the area inside the heat dissipation shell, which can effectively prevent heat from being transferred to the heat dissipation shell and reduce the heat loss from inside the product to outside the product.

By rotating, it can control whether the water outlet pipe is dispensing water and the amount of water dispensed. The float (6a) floats on the water in the pool and is connected to the valve body part (6b) through the handle (6c). It can control whether the faucet is open or closed and the amount of water flow by controlling the rotation angle of the valve body part (6b) according to the water level. The water pump (5) is located outside the heat dissipation shell assembly and is connected to two water pipes. One end of one water pipe extends into the pool formed by the bottom plate, and the other water pipe, through the pressure of the water pump, delivers water to the first-level water storage area on the upper wall.

10. A high-safety lithium-ion battery energy storage product with thermal management function based on new energy sources, as described in claim 1, characterized in that: Multiple water guide plates are fixed on the left, right and rear sides of the heat dissipation shell (1a).
