[0066] The module-less battery product structure is an innovative battery pack design that abandons the traditional battery module hierarchy and directly integrates the battery cells into the battery pack shell or frame. It aims to improve the energy density of the battery system, reduce weight, reduce costs, and simplify the manufacturing and assembly process of the battery pack.

[0067] The module-less battery product structure directly fixes the battery cell to the casing, resulting in partial or complete exposure of the cell, posing challenges to the sealing of the battery pack. If the seal is poor or the seal is aged and damaged, water and other foreign matter may seep into the casing through the disassembly interface, causing problems such as cell short circuits and corrosion. The exposed portion of the cell is more likely to become a channel for water to penetrate.

[0068] In view of this, please see Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present application provides an energy storage power supply 100. The energy storage power supply 100 includes a housing 10, a seal 20 and a plurality of battery cells 30. The battery cells 30 include electrodes and / or explosion-proof valves 34. A housing 101 for accommodating the battery cells 30 is formed inside the housing 10. The housing 10 has a mounting wall 11. The mounting wall 11 is located on one side of the housing chamber 101 and is formed with a fixing structure for fixing the battery cells 30. A through-hole 111 is formed at a corresponding position of the fixing structure. The electrodes and / or explosion-proof valves 34 of the battery cells 30 are connected to the outside of the housing chamber 101 through the through-hole 111. The seal 20 is covered on a side of the mounting wall 11 away from the housing chamber 101 to isolate the battery cells 30 from the outside. A groove is formed on the periphery of one of the seal 20 and the mounting wall 11, and a protrusion is formed on the periphery of the other. The protrusion is inserted into the groove.

[0069] Thus, the energy storage power supply 100 of the present application accommodates the battery cell 30 via the housing 10's internal cavity 101. The through-holes 111 of the mounting wall 11 of the housing 10 are designed to connect the battery cell 30 to external devices. The design in which the protrusion of one of the seal 20 and the mounting wall 11 is inserted into the groove of the other ensures a tight fit between the seal 20 and the housing 10, effectively preventing water and other foreign matter from penetrating the interior of the housing through the joint.

[0070] Specifically, the energy storage power supply 100 is made of plastic, which has low density, high strength, and good insulation properties, and helps to ensure the safety of the battery cell 30 .

[0071] Alternatively, in one embodiment, the energy storage power supply 100 of the present invention can be used as an outdoor power supply for outdoor use. For example, when camping, the user can use the energy storage power supply 100 to power and charge electrical appliances, lighting, mobile phones, tablet computers, etc.

[0072] Alternatively, in one embodiment, the energy storage power supply 100 of the present invention can be used as an indoor power source for indoor use. For example, the user can charge the energy storage power supply 100 with an external power source. If the user's home power outage occurs, the energy storage power supply 100 can be used to power appliances, lights, mobile phones, tablet computers, etc.

[0073] The energy storage power supply 100 includes a housing 10, a seal 20, and a battery cell 30. The housing 10 defines a chamber 101 for accommodating the battery cell 30, providing a stable and secure storage environment for the battery cell 30. The housing 10 also securely secures the battery cell 30 and other internal components in place through its internal structure and fixtures, preventing them from loosening or shifting during transportation and use.

[0074] The seal 20 covers the mounting wall 11 of the housing 10 to isolate the mounting wall 11 from the outside, thereby effectively preventing external substances such as water and dust from entering the interior of the housing 10 through the mounting wall 11, protecting the battery cell 30 and other internal components from contamination and damage.

[0075] Furthermore, a groove is formed on the periphery of one of the sealing member 20 and the mounting wall 11, and a protrusion is formed on the periphery of the other. The protrusion is inserted into the groove, and the insertion can be in the following two forms:

[0076] Please combine Figure 4 The sealing member 20 is provided with a groove at its periphery, and the mounting wall 11 is provided with a protrusion at its periphery, thereby providing a more stable support and fixing effect.

[0077] Please combine Figure 5 , the periphery of the seal 20 forms a protrusion and the periphery of the mounting wall 11 forms a groove, so that it is more convenient to remove the seal 20. In either case, as long as the design of the protrusion and the groove is reasonable and the fit is tight, a good sealing effect can be achieved.

[0078] The battery cell 30 can be a secondary battery or a primary battery cell. The battery cell 30 can be a lithium-sulfur battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell. The battery cell 30 can be cylindrical, flat, rectangular, or in other shapes. In this embodiment, the battery cell 30 can be described as a cylindrical shape. One or more battery cells 30 are provided in the accommodating cavity 101. The multiple battery cells 30 can be electrically connected in series, in parallel, or in a mixed manner. Mixed connection can refer to both series and parallel connection between the multiple battery cells 30. Each battery cell 30 includes two electrodes and an explosion-proof valve 34. The electrodes are respectively provided at both ends of the battery cell 30. One of the electrodes and / or the explosion-proof valve 34 can be connected to the outside of the accommodating cavity 101 through the through hole 111.

[0079] In some embodiments, the groove is filled with glue.

[0080] Specifically, there may be water accumulation or wet ground, and moisture may enter from the gap between the groove and the protrusion. To this end, the groove can be filled with glue. On the one hand, the glue can bond the seal 20 and the shell 10, and on the other hand, it can also play a waterproof function.

[0081] The material used for adhesives should be characterized by excellent waterproofing, moisture resistance, corrosion resistance, and insulation properties. Polyurethane adhesive or acrylate adhesive can be used. Polyurethane adhesive is a commonly used adhesive with excellent bonding properties and water resistance. Polyurethane adhesive contains a large number of urethane bonds in its molecular structure, which gives it high cohesion and adhesion, enabling it to firmly bond to a variety of materials, including metals, plastics, and rubber. Polyurethane adhesive also exhibits excellent water and weather resistance, maintaining long-term adhesion in humid or harsh environments. Acrylate adhesives also offer excellent bonding properties and waterproofing. The molecular structure of acrylate adhesives contains a large number of acrylate groups, which give them high reactivity and adhesion, allowing them to cure quickly and form strong chemical bonds with the adherend surface. Acrylate adhesives also have excellent water and chemical resistance, maintaining stable adhesion in water and various chemical media.

[0082] See also Figure 10 and Figure 11 In some embodiments, an elastic seal 13 is placed in the groove, and the protrusion abuts against the elastic seal 13.

[0083] Specifically, the main function of the elastic seal 13 is to provide a sealing effect to prevent external substances such as water and dust from entering the interior of the housing through the gaps, thereby protecting the internal battery cells 30 and other components from contamination and damage.

[0084] The elastic sealing member 13 is placed in the groove and fits tightly against the wall of the groove. This design ensures a gap-free connection between the sealing member and the housing 10, thereby improving the reliability of the seal.

[0085] The protrusion abuts against the elastic seal 13. When the groove and the protrusion are engaged, the protrusion squeezes the elastic seal 13 in the groove, causing it to further deform and tightly fill the tiny gap between the groove and the protrusion. This abutment not only enhances the sealing effect, but also improves the stability of the connection.

[0086] The elastic sealing member 13 can be made of a material with good elasticity and aging resistance, such as rubber, silicone, etc. These materials can maintain stable performance during long-term use and are not prone to aging and hardening.

[0087] See also Figure 2 In some embodiments, the seal 20 is a cover plate, and a mounting groove 112 is formed on the side of the mounting wall 11 away from the accommodating cavity 101, a through hole 111 is formed at the bottom of the mounting groove 112, the seal 20 covers the mounting groove 112, a groove is formed around the periphery of the mounting groove 112, and a protrusion is formed around the periphery of the seal 20.

[0088] Specifically, a groove is formed around the mounting groove 112 of the mounting wall 11 , and its shape and size match the shape and size of the protrusion of the seal 20 , so that the seal 20 can be accurately placed in the mounting groove 112 , thereby achieving positioning and fixation.

[0089] A through hole 111 is formed at the bottom of the mounting groove 112 for electrical connection. The through hole 111 allows current to pass through to meet the working requirements of the battery cell 30 in the housing 10 .

[0090] A plurality of pillars 12 are further provided in the housing 10 to provide support and protect the battery cells 30 and other electronic components inside the housing from damage due to squeezing.

[0091] The raised portion on the periphery of seal 20 naturally aligns with the groove and embeds within it. As seal 20 is pressed further downward, the raised portion is squeezed by the groove and deforms to a certain extent, thereby forming close contact with the wall of the groove. This contact not only establishes a physical connection between seal 20 and housing 10, but also enhances the stability and sealing of the connection through the compressive force between the raised portion and the groove. The close contact and compressive force between the raised portion and the groove achieve a good sealing effect, effectively preventing foreign matter such as water and dust from entering the interior of housing 10.

[0092] See also Figure 1 and Figure 3In some embodiments, the mounting wall 11 and the seal 20 form an accommodating space 40, the electrodes of the battery cell 30 are connected to the accommodating space 40 through the through hole 111, and the accommodating space 40 is provided with a bus 50, which is electrically connected to the electrodes of the battery cell 30.

[0093] Please combine Figure 7 and Figure 8 The battery cell 30 can be a cylindrical battery cell. The battery cell 30 includes a body 31, a first pole 32, and a second pole 33. The first pole 32 and the second pole 33 are respectively provided at the ends of the length direction of the body 31. The battery cell 30 can be placed vertically in the accommodating cavity 101, with its vertical direction corresponding to the length direction of its body 21.

[0094] The busbar 50 is a metal bar or plate used to collect and distribute electrical current. It can be made of copper, aluminum, nickel, or an alloy. After the busbar 50 is secured in place using a work fixture, it can be laser welded to the first or second pole 32, 33 of the battery cell 30. It is understood that the electrical connection between the busbar 50 and the poles of the battery cell 30 can also be achieved through other connection methods, such as twisting or pressing.

[0095] The busbar 50 connects the electrodes of multiple battery cells 30 to form an integrated current transmission network, which ensures that current can flow evenly through each battery cell 30, thereby improving the overall performance and safety of the battery module.

[0096] The energy storage power supply 100 may also include an acquisition board 60, a circuit board specifically designed to collect status information from the battery cells 30. Using high-precision sensors or measurement circuits, the acquisition board 60 collects analog signals such as the voltage, current, and temperature of the battery cells 30 and converts them into digital signals for subsequent processing. By monitoring and collecting status information from the battery cells 30 in real time, the operating status of the battery cells 30 can be accurately understood, allowing timely implementation of appropriate control measures, thereby avoiding potential safety risks such as overcharging, over-discharging, and overheating of the battery cells 30, and improving the battery cells' 30 lifespan and performance.

[0097] The busbar 50 includes a first busbar 501 and a second busbar 502, and the acquisition board 60 includes a first acquisition board 601 and a second acquisition board 602. The first acquisition board 601 can be secured to a corresponding position on the first busbar 501 using screws, and the second acquisition board 602 can be secured to a corresponding position on the first busbar 502 using screws. After securing the acquisition board 60, the nickel strip of the first acquisition board 601 can be connected to the first busbar 501 using an electrical connection method such as laser welding, thereby achieving an electrical connection between the first acquisition board 601 and the first busbar 501. The acquisition assembly can be used to collect status information of the battery cells 30. This status information of the battery cells 30 may include information such as the voltage, current, and temperature of each battery cell 30.

[0098] See also Figure 3 A sealing ring 70 is provided between the sealing member 20 and the outer wall of the housing 10 to enhance the sealing effect and thereby isolate the bus from external moisture.

[0099] See also Figure 9 In some embodiments, the mounting wall 11 and the sealing member 20 form an accommodating space 40 , and the explosion-proof valve is connected to the accommodating space 40 through the through hole 111 .

[0100] The explosion-proof valve 34 is installed on the battery cell 30 and communicates with the storage space 40 via the through-hole 111. The primary function of the explosion-proof valve 34 installed on the battery cell 30 is to automatically release pressure when the internal pressure of the battery cell 30 is too high, thereby preventing the battery cell 30 from exploding. When the internal pressure of the battery cell 30 exceeds a set value, the explosion-proof valve 34 automatically opens or ruptures, allowing the internal gas or liquid to quickly escape from the storage space 40, thereby reducing the pressure within the battery cell 30. Therefore, in the event of thermal runaway in the battery cell 30, the material ejected from the explosion-proof valve 34 can be sprayed into the storage space 40 through the through-hole 111, thereby preventing the spread of thermal runaway to a certain extent.

[0101] Specifically, during operation, the battery cell 30 may release gas, causing the pressure inside the battery cell 30 to increase. When the pressure is high, the explosion-proof valve 34 can rupture to release the substances (such as gas, liquid, etc.) inside the battery cell 30. The explosion-proof valve 34 is connected to the accommodating space 40 through the first through hole 111. The substances ejected from the explosion-proof valve 34 can be sprayed into the accommodating space 40. The accommodating space 40 isolates the substances ejected from the explosion-proof valve 34 from the other battery cells 30 in the accommodating chamber 101, thereby preventing the thermal runaway of a battery cell 30 from spreading to other battery cells 30 to a certain extent, thereby improving the safety of the energy storage power supply 100.

[0102] In some embodiments, the accommodating space 40 is further provided with a pressure relief channel communicating with the accommodating cavity 101 or the outside of the housing 10 .

[0103] To further ensure safety, the accommodating space 40 is also provided with a pressure relief passage that communicates with the accommodating chamber 101 or the outside of the housing 10. This passage allows the gas or liquid in the accommodating space 40 to be smoothly discharged to the external environment after the explosion-proof valve 34 releases pressure, thereby preventing accumulation in the accommodating space 40 and potentially causing danger.

[0104] In some embodiments, the mounting wall 11 is disposed at the bottom of the housing 10 .

[0105] The mounting wall 11 is located at the bottom of the housing 10 and provides a stable support for the battery cell 30 or other mounted components. This design helps ensure the stability of the battery cell 30 during operation and reduces the risk of damage caused by vibration or impact.

[0106] The bottom of the housing 10 is provided with a mounting wall 11 . On one hand, the joint formed between the sealing member 20 and the housing 10 is not easily visible. On the other hand, the gravity of the entire product can make the joint between the sealing member 20 and the housing 10 more stable.

[0107] The bottom mounting wall 11 may also be provided for heat dissipation design. If the battery cell 30 generates a large amount of heat during operation, the bottom of the housing 10 may be designed with a heat sink, heat dissipation holes, or a structure connected to other heat dissipation systems to effectively dissipate the heat to the external environment.

[0108] See also Figure 8 In some embodiments, the fixing structure is a receiving groove 102 , one end of the battery cell 30 is inserted into the receiving groove 102 , and a through hole 111 is provided at the bottom of the receiving groove 102 .

[0109] Optionally, the receiving slots 102 may include multiple receiving slots 102, which are arranged in a matrix, so that the multiple battery cells 30 are also arranged in a matrix accordingly. As a result, the arrangement of the multiple battery cells 30 is more regular, which is conducive to improving the space utilization of the energy storage power supply 100. The shape of the receiving slot 28 is adapted to the shape of the battery cell 30, so as to more effectively fix and limit the battery cell 30. Figure 6 In the embodiment, the battery cell 30 is cylindrical, and the receiving groove 102 is also cylindrical accordingly.

[0110] In this way, the receiving groove 102 can restrict the battery cell 30 to prevent the battery cell 30 from shaking during the use of the energy storage power supply 100 and affecting the normal use of the energy storage power supply 100.

[0111] See also Figure 8 and Figure 13 In some embodiments, the energy storage power supply 100 includes a fixing bracket 80 , which is connected to the inner wall of the accommodating cavity 101 to fix the battery cell 30 to the fixed structure.

[0112] Specifically, the fixing bracket 80 is arranged in the accommodating cavity 101 and is fixedly connected to the inner wall of the accommodating cavity 101. The fixing bracket 80 is arranged at one end of the battery cell 30 away from the fixed structure. The fixing bracket 80 and the fixed structure can clamp the battery cell 30 in the up and down directions so that the battery cell 30 is more stably fixed in the accommodating cavity 101. Therefore, the fixing bracket 80 can further enhance the stability of the battery cell 30.

[0113] In some embodiments, the energy storage power supply 100 further includes an inverter, which is disposed in the accommodating cavity 101 and electrically connected to the battery cell 30 , and is fixedly disposed on the fixing bracket 80 .

[0114] Specifically, the inverter is one of the core components of the energy storage power supply 100. It is located within the housing 101, allowing the housing 10 to protect the inverter. The inverter 16 is electrically connected to the battery cells 30 and can convert the DC power from the battery cells 30 into AC power to power AC-powered appliances. Optionally, the energy storage power supply 100 can also output DC power to power electronic devices that use DC power.

[0115] Furthermore, the inverter 16 can be arranged on the side of the fixing bracket 80 away from the battery cell 30, so that the fixing bracket 80 can be used to fix the inverter 16, which can reduce the number of additional components for fixing the inverter, and can reduce the volume and weight of the energy storage power supply 100 to a certain extent, thereby improving the portability of the energy storage power supply 100 and reducing the manufacturing cost of the energy storage power supply 100.

[0116] As can be understood, the performance of the inverter directly affects the output quality and efficiency of the energy storage power supply 100. Therefore, in design and selection, priority is given to inverters with high conversion efficiency, high stability, and good heat dissipation performance. The inverter is fixed to the fixed bracket 82 to ensure its stable position within the energy storage power supply 100 and facilitate heat dissipation and maintenance.

[0117] See also Figure 1 and Figure 12 In some embodiments, one of the mounting wall 11 or the sealing member 20 is provided with a support structure, the support structure abutting against the other of the mounting wall or the sealing member 20 .

[0118] In the battery module, the seal 20 is a large plastic plate secured only by its perimeter. This can cause the center to collapse or bulge, affecting the overall stability and sealing of the energy storage power supply 100. To address this issue, a support structure can be installed on either the mounting wall 11 or the seal 20 to ensure the flatness and stability of the seal 20.

[0119] The support structure is mounted on the mounting wall 11 or the seal 20 to ensure a tight abutment between the mounting wall 11 and the seal 20. When installing the support structure on the mounting wall 11, it is necessary to ensure that the support structure does not interfere with the battery cells 30 or other internal components. When installing the support structure on the seal 20, it should be designed to match the corresponding portion on the mounting wall 11 to ensure a tight fit during assembly.

[0120] The support structure can be designed as multiple point supports, columnar supports or mesh supports to disperse and support the weight of the seal 20. Point supports are suitable for smaller, irregularly shaped parts of the model, and can provide stable support points at key positions to effectively prevent local collapse. The point support design is flexible and can be precisely adjusted according to the shape and weight distribution of the seal 20. By precisely arranging the support points, the point support can minimize the impact on the overall appearance and structure of the seal 20, maintaining the aesthetics and functionality of the product. However, point supports may have certain limitations in the support range, and the strength requirements for the material are also relatively high. The columnar support is composed of a plurality of cylindrical arrays, has greater structural strength and rigidity, and can withstand greater pressure and loads. The mesh support is formed by a grid interwoven with multiple sheet supports, and performs well in terms of structural strength, material saving and heat dissipation, but the production and installation process of the mesh support is relatively complicated.

[0121] See also Figure 12-14 In some embodiments, the supporting structure is a support column 21, one of the mounting wall 11 or the seal 20 is provided with the support column 21, and the other of the mounting wall 11 or the seal 30 is provided with a support groove 113, and the support column 21 is inserted into the support groove 113.

[0122] In this embodiment, support columns 21 are evenly distributed on the seal 20, and support grooves 113 are evenly distributed on the mounting wall 11 to cooperate with the support columns 21. The abutment between the support columns 21 and the support grooves 113 provides a support function, preventing the seal 20 from collapsing and pressing against the busbar or causing deformation of the seal 20 that would affect its appearance.

[0123] See also Figure 13 and Figure 14 In some embodiments, the seal 20 is provided with reinforcing ribs, and the supporting structure is provided on the reinforcing ribs.

[0124] It should be noted that reinforcement is a structural element added to the interior or exterior of a structure. Reinforcement usually takes the form of plates, strips, or other shapes, and is used to increase the load-bearing capacity and stability of the original structure.

[0125] The reinforcing ribs protrude from the seal 20 toward the housing 10 and are in a grid or honeycomb shape. The specific shape is not limited. For example, see Figure 13 The reinforcement ribs are in a grid shape, and the reinforcement ribs include multiple transverse reinforcement ribs 23 and multiple longitudinal reinforcement ribs 24. The extension direction of the transverse reinforcement ribs 23 is perpendicular to that of the longitudinal reinforcement ribs 24, and the support structure is set at the intersection of the transverse reinforcement ribs 23 and the longitudinal reinforcement ribs 24. Among them, the transverse reinforcement ribs 23 extend along the width or short side direction of the structure, and their main function is to enhance the rigidity and strength of the structure in the transverse direction. The transverse reinforcement ribs 23 can effectively resist pressure or shear force from the side and prevent the structure from being excessively deformed or damaged in the transverse direction. The longitudinal reinforcement ribs 24 extend along the length or long side direction of the structure, and their main function is to enhance the rigidity and strength of the structure in the longitudinal direction. The longitudinal reinforcement ribs 24 can withstand tension or pressure from both ends of the structure to ensure that the structure remains stable in the longitudinal direction. When the extension direction of the transverse reinforcement ribs 23 is perpendicular to that of the longitudinal reinforcement ribs 24, the transverse reinforcement ribs 23 and the longitudinal reinforcement ribs 24 together form a grid-like structural system. The grid-like structural system can more effectively disperse and bear loads from all directions, thereby improving the bearing capacity and stability of the overall structure.

[0126] Thus, providing reinforcing ribs on the seal 20 increases the rigidity and strength of the seal 20, enabling the seal 20 to better resist external forces such as bending and impact. Providing support structures on the reinforcing ribs further enhances the load-bearing capacity of these areas, allowing the seal 20 to withstand greater weight and pressure.

[0127] In some embodiments, a buckle is provided on one of the sealing member 20 or the mounting wall 11 , the supporting structure is a hook, and the buckle is locked and connected with the hook.

[0128] The use of a snap-on and hook-on connection method to achieve fixation between the seal 20 and the mounting wall 11 is a convenient and reliable assembly method, which enables the energy storage power supply 100 to quickly install and remove the seal 20.

[0129] The buckle is a resilient structure mounted on either the seal 20 or the mounting wall 11. It has a groove or hole inside that accommodates and locks the hook. When the buckle and hook engage, they generate a preload to ensure a secure connection.

[0130] The hook is part of the supporting structure and is provided on the other of the seal 20 or the mounting wall 11. The shape and size of the hook match those of the buckle and can be easily inserted into the groove or hole of the buckle and locked by the elastic action of the buckle after insertion.

[0131] The clamping connection mode of the buckle and the hook makes the installation and removal process of the sealing member 20 very simple and quick, without the need for additional tools or complicated operating steps.
