Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to a battery and an electric device. BACKGROUND

[0002] In the related technical field, a battery is a device that converts chemical energy into electrical energy by internal chemical reactions to generate current. Common batteries include dry batteries, rechargeable batteries, and other types, which are widely used in remote controls, mobile phones, cars, and other devices.

[0003] However, the current battery heat preservation effect is not satisfactory, and the root cause is that the mechanism of temperature transfer of the battery cell is not thoroughly explored, and corresponding solutions are not taken. In most cases, the heat in the box is mainly transferred to the bottom of the liquid cooling plate through the battery cell, and then transferred to the metal box by the liquid cooling plate, and then exchanged with the external low temperature environment, which leads to the loss of the battery cell temperature, thereby adversely affecting the performance of the battery cell. Moreover, if the heat preservation measures are increased in the system, although the heat loss can be reduced to a certain extent, this method may have a negative impact on the temperature control effect of the liquid cooling plate, thereby weakening its temperature control ability and increasing the manufacturing difficulty and cost.

[0004] Therefore, there is an urgent need for a battery that can effectively block the loss of heat and simplify the battery manufacturing process. Invention content

[0005] The present application provides a battery and an electric device, which can effectively block the loss of heat, ensure that the heat preservation effect of the heat preservation structure is better, and simplify the manufacturing process of the battery and possibly reduce the cost.

[0006] In a first aspect, the present application provides a battery, which comprises a box, a heat preservation structure, and a battery cell assembly.

[0007] The box has a containing cavity. The heat preservation structure is installed in the containing cavity, and at least one partition groove is provided on the heat preservation structure.

[0008] The battery cell assembly comprises at least one battery cell unit, the battery cell unit is installed in the containing cavity, and the battery cell unit is embedded in the partition groove.

[0009] Among them, the heat preservation edge enclosing the partition groove at least partially extends between the adjacent two battery cell units.

[0010] Based on the above embodiment, the box is the shell of the entire battery, responsible for protecting the internal components from the external environment. The containing cavity is located inside the box and is used to place and fix other key components to ensure stable operation of the battery. The heat preservation structure is installed inside the containing cavity, and the heat preservation structure is an important part for reducing heat loss or preventing external heat intrusion.

[0011] The heat preservation structure is provided with at least one partition groove. The presence of the partition groove can not only improve the assembly stability of the battery cell unit, but also provide better heat preservation effect for the battery cell unit.

[0012] The battery cell assembly is the core part of the battery, which includes at least one battery cell unit. The battery cell units are precisely installed in the accommodation cavities, and each battery cell unit is embedded in the partition groove on the heat preservation structure. Such design ensures the stability of the battery cell units in the battery.

[0013] In addition, in order to further improve the heat preservation effect, the heat preservation edges enclosing each partition groove at least partially extend between the adjacent two battery cell units. This design can effectively block the loss of heat and ensure that the heat preservation effect of the heat preservation structure is better.

[0014] In some examples, the heat preservation structure includes a heat preservation body, a first heat preservation edge and a second heat preservation edge. The heat preservation body is arranged on one side of the battery cell assembly.

[0015] The first heat preservation edge is arranged on the heat preservation body, and the first heat preservation edge extends towards the direction of the battery cell assembly. The first heat preservation edge is located at the side of the battery cell unit, or the first heat preservation edge is located between the adjacent two battery cell units.

[0016] The second heat preservation edge is arranged on the heat preservation body, and the second heat preservation edge extends towards the direction of the battery cell assembly. The second heat preservation edge is located between the adjacent two battery cell units, and the height of the second heat preservation edge relative to the heat preservation body is greater than the height of the first heat preservation edge relative to the heat preservation body.

[0017] The first heat preservation edge and the second heat preservation edge cooperate with the heat preservation body to enclose the partition groove.

[0018] The heat preservation body is the core part of the heat preservation structure, which is usually composed of high-efficiency heat preservation material to ensure that the heat is well maintained in the device. The first heat preservation edge is located at one edge of the heat preservation body or as a partition edge to form a partition groove, which plays a role in strengthening the heat preservation effect and the structural strength. The second heat preservation edge is similar to the first heat preservation edge, which also serves to enhance the heat preservation effect and the stability of the structure. The partition groove is a part in the heat preservation structure for partitioning different areas, which helps to further improve the heat preservation performance.

[0019] In some examples, the height of the first heat preservation edge is M, the height of the battery cell unit is L, and 1mm≤M≤0.1L.

[0020] In the above structure, the height of the first heat preservation ridge is set as M, and the height of the battery cell unit is L. According to the design requirements, it is ensured that the height of the first heat preservation ridge is not less than 1mm, and the maximum height range of the first heat preservation ridge does not exceed one tenth of the height of the battery cell unit, that is, 1mm≤M≤0.1L. Through such size setting, the first heat preservation ridge can form a certain height difference between the adjacent two battery cell units. Such design neither causes interference to the subsequent liquid cooling assembly arrangement, nor effectively improves the heat preservation performance of the heat preservation structure, ensures that the temperature of the battery during operation is controlled within the ideal range, thereby improving the stability and safety of the entire battery system.

[0021] In some examples, the height of the second heat preservation ridge is N, the height of the battery cell unit is L, and 2 / 3L≤N.

[0022] In the above structure, the height of the second heat preservation ridge is set as N, and the height of the battery cell unit is L. According to the design requirements, there is a specific proportional relationship between the height N of the second heat preservation ridge and the height L of the battery cell unit, that is, 2 / 3L≤N. This design arrangement ensures that the second heat preservation ridge and the battery cell unit can have sufficient contact area. Such contact area can expand the heat preservation range of the second heat preservation ridge. Through such design, the heat preservation performance of the entire heat preservation structure can be effectively improved, ensuring that the battery cell unit can obtain more stable and efficient heat preservation effect during work, thereby protecting the normal operation of the entire system and prolonging the service life of the battery cell unit.

[0023] In some examples, the heat preservation structure is arranged at the bottom of the battery cell assembly.

[0024] After arranging the heat preservation structure at the bottom of the battery cell assembly, the bottom liquid cooling plate can be omitted, so that the heat preservation range of the heat preservation structure is larger and the heat preservation effect is improved. In winter, the temperature of the battery cell assembly can be better maintained at the working temperature, improving the use performance of the battery in cold environment.

[0025] In some examples, the heat conduction coefficient of the heat preservation structure is less than or equal to 0.05.

[0026] In the above structure, the heat conduction coefficient of the heat preservation structure is less than or equal to 0.05. Such design can ensure that the heat preservation structure has more outstanding heat preservation effect, thereby maintaining the stability and durability of the temperature in various application occasions.

[0027] The low heat conduction coefficient of the heat preservation structure means that the rate of heat transfer is significantly reduced, which helps to maintain the temperature of the internal environment.

[0028] In addition, the low heat conduction characteristic of the heat preservation structure also performs well in energy efficiency, because the loss of heat is reduced, thereby reducing the consumption of energy.

[0029] In some examples, the thickness of the heat preservation structure is b, and 1mm≤b≤3mm.

[0030] In some specific examples, the thickness of the heat preservation structure is set to b, and the thickness is in the range of 1mm to 3mm, i.e. 1mm≤b≤3mm. Through such a thickness design, it can be ensured that the heat preservation structure not only plays its heat preservation effect, but also gives the heat preservation structure a certain strength. The giving of such strength makes the heat preservation structure not only able to maintain temperature, but also able to provide certain support and positioning performance, so as to be more stable and reliable in actual application.

[0031] In some examples, the battery further includes a liquid cooling assembly including at least one side liquid cooling plate disposed on a side of the cell unit.

[0032] Through the cooperation of the liquid cooling assembly, the present application forms a new battery box heat preservation liquid cooling system for the battery pack structure mode. The main design scheme is to use a heat preservation foam (heat preservation structure) with a groove to embed each cell of the whole pack inside. The side of the cell and the side of the cell in contact with the heat preservation foam have a certain height, which replaces the traditional heat insulation pad under the action of heat preservation. The side or large surface of the cell is bonded with a side liquid cooling plate, which has a temperature control effect on the cell.

[0033] In some examples, the plurality of cell units are arranged in a row, and the battery includes a plurality of rows of cell units.

[0034] In each row of cell units, a second heat preservation rib of the heat preservation structure is arranged between two adjacent cell units.

[0035] A side liquid cooling plate is arranged between two adjacent rows of cell units, and a plurality of side liquid cooling plates are connected in parallel through a liquid cooling pipeline.

[0036] In the above structure, the plurality of cell units are arranged in a row, and the whole battery system is composed of a plurality of rows of such cell units.

[0037] In each row of cell units, it can be seen that a second heat preservation rib is arranged between two adjacent cell units, and the heat preservation rib is part of the heat preservation structure, which is used to maintain the temperature stability of the cell unit.

[0038] In addition, between two adjacent rows of cell units, the designer ingeniously arranges the side liquid cooling plates, which are connected to each other through a liquid cooling pipeline and are arranged in parallel. Such a design helps to effectively cool the battery and ensure that the temperature of the battery during operation is within a safe range.

[0039] In a second aspect, the application provides a battery and a device body, wherein the battery is arranged in the assembly cavity of the device body.

[0040] With the battery, the battery-powered device can effectively block the loss of heat, ensure that the heat preservation effect of the heat preservation structure is better, and simplify the manufacturing process of the battery and possibly reduce costs, thereby reducing the manufacturing cost of the battery-powered device.

[0041] Further, in the above structure, the battery-powered device is composed of several key parts. The device includes a battery, which is a power supply component. The device also includes a main body part, which has a space called an assembly cavity, and the battery is installed inside the assembly cavity. In addition, the battery-powered device also includes several other modules: a driving module, a control module, and tires. The driving module is responsible for providing power to the device, the battery can provide energy for the driving module, the control module is responsible for controlling the operation of the device, and the tires are the parts that contact the ground when the device moves, ensuring that the device can move stably on various ground surfaces.

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0056] In order to solve the above technical problems, please refer to Figures 1-9 The first aspect of the present application proposes a battery 1100 which can effectively block the loss of heat, ensure that the heat preservation effect of the heat preservation structure 200 is better, and simplify the manufacturing process of the battery 1100 and possibly reduce the cost.

[0057] Referring to Figures 1-3 In some examples, the present application provides a battery 1100, which includes a box body 100, a heat preservation structure 200 and a battery cell assembly 300.

[0058] The box body 100 has a containing cavity 110. The heat preservation structure 200 is installed in the containing cavity 110, and the heat preservation structure 200 is provided with at least one separation groove 240. The separation groove 240 can improve the assembly stability of the battery cell unit and can better preserve the battery cell unit.

[0059] The battery cell assembly 300 includes at least one battery cell unit, the battery cell unit is installed in the containing cavity 110, and the battery cell unit is embedded in the separation groove 240.

[0060] Among them, the heat preservation rib enclosing the separation groove 240 at least partially extends between the adjacent two battery cell units, which can further ensure the heat preservation effect of the heat preservation structure 200.

[0061] Based on the above embodiments, the box 100 is the outer shell of the entire battery 1100, responsible for protecting the internal components from the external environment. The accommodation cavity 110 is located inside the box 100, used to place and fix other key components, ensuring the stable operation of the battery 1100. The heat preservation structure 200 is installed inside the accommodation cavity 110, and the heat preservation structure 200 is an important part to reduce heat loss or prevent external heat intrusion.

[0062] The heat preservation structure 200 is provided with at least one groove 240. The presence of the groove 240 not only improves the assembly stability of the battery cell unit, but also provides better heat preservation effect for the battery cell unit.

[0063] The battery cell assembly 300 is the core part of the battery 1100, which includes at least one battery cell unit. These battery cell units are precisely installed in the accommodation cavity 110, and each battery cell unit is embedded in the groove 240 on the heat preservation structure 200. Such design ensures the stability of the battery cell unit inside the battery 1100.

[0064] In addition, in order to further improve the heat preservation effect, the heat preservation edge enclosing each groove 240 at least partially extends between the two adjacent battery cell units. This design can effectively block the loss of heat, ensuring that the heat preservation effect of the heat preservation structure 200 is better.

[0065] By adopting this groove type heat preservation structure 200, each battery cell unit in the whole package can be embedded into the groove 240. In this structure, the side surface of the battery cell unit in contact with the battery cell unit has a certain height, which not only plays a key role in heat preservation, but also can replace the heat insulation pad used in the traditional battery 1100 design, thereby simplifying the manufacturing process of the battery 1100 and possibly reducing the cost.

[0066] The shape of the heat preservation structure 200 is pre-set and shaped before assembly, which means that the battery cell can be precisely positioned through the groove 240, thereby significantly improving the assembly stability of the battery cell unit. Through the close cooperation between the carefully designed groove 240 and the battery cell unit, a more outstanding heat preservation effect can be achieved, ensuring the performance and safety of the battery 1100 in various working environments.

[0067] Referring to Figures 1-3 In some examples, the heat preservation structure 200 includes a heat preservation body 210, a first heat preservation edge 220, and a second heat preservation edge 230. The heat preservation body 210 is arranged on one side of the battery cell assembly 300.

[0068] The first heat preservation rib 220 is arranged on the heat preservation main body 210 and extends towards the direction of the battery cell assembly 300. The first heat preservation rib 220 is located at the circumferential side of the battery cell unit or between two adjacent battery cell units.

[0069] The second heat preservation rib 230 is arranged on the heat preservation main body 210 and extends towards the direction of the battery cell assembly 300. The second heat preservation rib 230 is located between two adjacent battery cell units, and the height of the second heat preservation rib 230 relative to the heat preservation main body 210 is greater than the height of the first heat preservation rib 220 relative to the heat preservation main body 210.

[0070] The first heat preservation rib 220 and the second heat preservation rib 230 cooperate with the heat preservation main body 210 to form a partition groove 240.

[0071] The heat preservation main body 210 is the core part of the heat preservation structure 200 and is usually composed of high-efficiency heat preservation materials to ensure that the heat is well maintained inside the device. The first heat preservation rib 220 is located at one edge of the heat preservation main body 210 or as a partition rib to form the partition groove 240, which plays a role in strengthening the heat preservation effect and structural strength. The second heat preservation rib 230 is similar to the first heat preservation rib 220 and also serves to enhance the heat preservation effect and structural stability. The partition groove 240 is a part of the heat preservation structure 200 for separating different areas, which helps to further improve the heat preservation performance.

[0072] The first heat preservation rib 220 is arranged at a specific position of the heat preservation main body 210 and extends towards the direction of the battery cell assembly 300. The position of the first heat preservation rib 220 is either located at the circumferential side of the battery cell unit or between two adjacent battery cell units, thereby ensuring the distribution of the heat preservation effect. Multiple first heat preservation ribs 220 can also be arranged, and the positions of the first heat preservation ribs 220 can be partially located at the circumferential side of the battery cell unit and partially located between two adjacent battery cell units.

[0073] The second heat preservation rib 230 is arranged on the heat preservation main body 210 and also extends towards the direction of the battery cell assembly 300. The second heat preservation rib 230 is at least partially located between two adjacent battery cell units, and its height relative to the heat preservation main body 210 is precisely calculated to ensure that it has a higher height than the first heat preservation rib 220. Such a design can further enhance the overall performance of the heat preservation structure 200.

[0074] The first heat preservation rib 220 and the second heat preservation rib 230 cooperate with the heat preservation main body 210 to form a partition groove 240. The partition groove 240 not only helps to maintain the temperature of the battery cell assembly 300, but also provides installation space for other auxiliary components, thereby optimizing the overall battery 1100 package design while maintaining the performance of the battery cell.

[0075] Referring to Figure 4 In some examples, the height of the first heat preservation ridge 220 is M, the height of the cell unit is L, and 1mm≤M≤0.1L. Such a setting can make the first heat preservation ridge 220 of the heat preservation structure 200 have a certain height between two adjacent cell units, and will not affect the arrangement of the subsequent liquid cooling assembly 400, and can also improve the heat preservation effect of the heat preservation structure 200.

[0076] In the above structure, the height of the first heat preservation ridge 220 is set to M, and the height of the cell unit is L. According to the design requirements, it is ensured that the height of the first heat preservation ridge 220 is not less than 1mm, and the maximum height range of the first heat preservation ridge 220 will not exceed one tenth of the height of the cell unit, that is, 1mm≤M≤0.1L. Through such size setting, the first heat preservation ridge 220 can form a certain height difference between two adjacent cell units. Such design will neither interfere with the arrangement of the subsequent liquid cooling assembly 400, nor effectively improve the heat preservation performance of the heat preservation structure 200, so as to ensure that the temperature of the battery 1100 during operation is controlled within the ideal range, thereby improving the stability and safety of the entire battery 1100 system.

[0077] Referring to Figure 4 In some examples, the height of the second heat preservation ridge 230 is N, the height of the cell unit is L, and 2 / 3L≤N. Such a setting can make the second heat preservation ridge 230 and the cell unit have sufficient contact area, so that the heat preservation range of the second heat preservation ridge 230 is larger, and the heat preservation effect of the heat preservation structure 200 is improved.

[0078] In the above structure, the height of the second heat preservation ridge 230 is set to N, and the height of the cell unit is L. According to the design requirements, there is a specific proportional relationship between the height N of the second heat preservation ridge 230 and the height L of the cell unit, that is, 2 / 3L≤N. This design arrangement ensures that the second heat preservation ridge 230 and the cell unit can have sufficient contact area. Such contact area can make the heat preservation range of the second heat preservation ridge 230 be expanded. Through such design, the heat preservation performance of the entire heat preservation structure 200 can be effectively improved, so as to ensure that the cell unit can obtain more stable and efficient heat preservation effect during work, thereby protecting the normal operation of the entire system and prolonging the service life of the cell unit.

[0079] In some examples, the heat preservation structure 200 is arranged at the bottom of the cell assembly 300. After arranging the heat preservation structure 200 at the bottom of the cell assembly 300, the bottom liquid cooling plate can be omitted, so that the heat preservation range of the heat preservation structure 200 is larger, and the heat preservation effect is improved. In winter, the temperature of the cell assembly 300 can be better maintained at the working temperature, thereby improving the use performance of the battery 1100 in cold environment.

[0080] By ingeniously arranging the heat preservation structure 200 at the bottom of the battery cell assembly 300, the need for installing a liquid cooling plate at the bottom can be effectively avoided. Such a design not only simplifies the structure, but also significantly expands the heat preservation range of the heat preservation structure 200, thereby further improving the heat preservation effect. Especially in the cold winter conditions, such a design can effectively help the temperature of the battery cell assembly 300 to be maintained within the ideal working temperature range, thereby significantly improving the use performance and efficiency of the battery 1100 in cold environments.

[0081] The main purpose of arranging the heat preservation structure 200 is to reduce heat exchange between the battery 1100 and the external environment. In the cold winter, the heat preservation structure 200 can effectively reduce the dissipation of the internal temperature of the battery 1100, and in the hot summer, it can also effectively block the infiltration of external high temperature. Such a double protection mechanism ensures that the battery 1100 can maintain high and relatively stable use performance under various environmental conditions, thereby providing more reliable and durable power support for users.

[0082] In some examples, the thermal conductivity of the heat preservation structure 200 is less than or equal to 0.05. This can have better heat preservation effect.

[0083] In the above structure, the thermal conductivity of the heat preservation structure 200 is less than or equal to 0.05. Such a design can ensure that the heat preservation structure 200 has more outstanding heat preservation effect, thereby maintaining the stability and durability of the temperature in various application occasions.

[0084] The low thermal conductivity of the heat preservation structure 200 means that the rate of heat transfer is significantly reduced, which helps to maintain the temperature of the internal environment.

[0085] In addition, such a low thermal conductivity of the heat preservation structure 200 also performs well in terms of energy efficiency, because the loss of heat is reduced, thereby reducing the consumption of energy.

[0086] Specifically, the thermal conductivity of the heat preservation structure 200 can be 0.04 or 0.05. Both of these two values belong to the category of low thermal conductivity, which can ensure that the heat preservation structure 200 provides excellent heat preservation performance in actual application.

[0087] The heat preservation structure 200 between the battery cells is usually made of a material with a low thermal conductivity, such as polyurethane foam, mineral wool, or vacuum insulation panels, etc. These materials can effectively insulate heat transfer while maintaining temperature uniformity inside the battery 1100 group. In addition to considering the thermal conductivity, factors such as mechanical strength, chemical resistance, aging resistance, and cost-effectiveness should also be considered when selecting materials to ensure the long-term stability of the heat preservation structure 200 and the overall performance of the battery 1100. Such materials can effectively slow down the transfer of heat through the heat preservation structure 200 between the battery cells, thereby maintaining the battery cells within the ideal operating temperature range, ensuring stable operation of the device and prolonging the service life of the battery cells.

[0088] The heat preservation structure 200 can be at least one of polystyrene foam, polyurethane foam, rock wool, and slag wool.

[0089] There are several common types of heat preservation materials. One is mineral fiber materials such as rock wool and slag wool, which have a thermal conductivity of 0.03 to 0.05, making them very suitable for heat insulation. Another is foamed plastic materials such as polystyrene foam and polyurethane foam, which have a lower thermal conductivity of about 0.025, making them widely used in building insulation and refrigeration equipment.

[0090] In addition to the above materials, there is also a vacuum insulation panel, which greatly reduces the thermal conductivity of the internal gas by vacuumizing, so its thermal conductivity can be as low as 0.004, making it one of the lowest thermal conductivity insulation materials. In addition, some special composite materials can also achieve very low thermal conductivity by combining different materials in a specific way, meeting the insulation needs of specific fields.

[0091] In some examples, the thickness of the heat preservation structure 200 is b, and 1mm≤b≤3mm. Such thickness can make the heat preservation effect of the heat preservation structure 200 better, and can make the heat preservation structure 200 have a certain strength, and can have a certain supporting and positioning performance.

[0092] In some specific examples, the thickness of the heat preservation structure 200 is set to b, and the thickness is in the range of 1mm to 3mm, i.e. 1mm≤b≤3mm. Through such thickness design, the heat preservation structure 200 can not only play its heat preservation effect, but also give the heat preservation structure 200 a certain strength. The strength of the heat preservation structure 200 not only maintains the temperature, but also provides certain support and positioning performance, so as to be more stable and reliable in actual application.

[0093] That is, the thickness of the foam filled between the battery cell and the box 100 is between 1mm and 3mm. Correspondingly, the thickness of the foam filled between the battery cell and the box 100 can be in the range of 1mm to 3mm. Such a design not only ensures that the foam can effectively isolate the loss of heat and maintain the temperature of the battery cell, but also ensures that the foam has sufficient strength and rigidity in structure to support the battery cell and keep it in the correct position in the box 100.

[0094] Referring to Figure 5 In some examples, the battery 1100 also includes a liquid cooling assembly 400, which includes at least one side liquid cooling plate arranged on the side of the battery cell unit.

[0095] Through the cooperation of the liquid cooling assembly 400, the present application forms a new battery 1100 box heat preservation liquid cooling system for the battery 1100 package structure. The main design scheme is to use a heat preservation foam (heat preservation structure 200) with a partition groove 240 to embed each battery cell in the whole package. The side heat preservation foam that contacts the battery cell has a certain height, which replaces the traditional heat insulation pad under the action of heat preservation. The side or main surface of the battery cell is bonded with a side liquid cooling plate, which has a temperature control effect on the battery cell.

[0096] The liquid cooling assembly 400 is composed of at least one side liquid cooling plate, and these side liquid cooling plates are installed at the side of the battery cell unit.

[0097] With the cooperation of the liquid cooling assembly 400, the present application proposes an innovative battery 1100 box heat preservation liquid cooling system, which is particularly suitable for the CTP (Cell To Pack, i.e. battery 1100 package) structure. The core design concept is to use a heat preservation foam structure with a partition groove 240, which allows each battery cell in the battery 1100 package to be embedded in the corresponding groove. In this design, the side heat preservation foam that contacts the battery cell has a certain thickness, which not only provides effective heat preservation effect, but also replaces the heat insulation pad used in the traditional battery 1100 design to some extent. In addition, the side or main surface of the battery cell is bonded with a side liquid cooling plate, which can effectively control the temperature of the battery cell and ensure that the temperature of the battery 1100 during operation is within a safe and efficient range.

[0098] Referring to Figures 6-8 The side liquid cooling plate can be provided with three, and the three side liquid cooling plates can be connected in parallel, Figure 7 A liquid flow direction diagram of the liquid cooling assembly 400 in the battery 1100. It does not represent that the liquid cooling assembly 400 of the present application can only adopt this liquid flow mode, and the specific setting is based on actual needs.

[0099] In some examples, the plurality of battery cell units are arranged in a row, and the battery 1100 comprises a plurality of rows of battery cell units.

[0100] In each row of battery cell units, a second heat preservation rib 230 of the heat preservation structure 200 is arranged between two adjacent battery cell units.

[0101] A side liquid cooling plate is arranged between two adjacent rows of battery cell units, and a plurality of side liquid cooling plates are connected by liquid cooling pipes in parallel.

[0102] In the above structure, the plurality of battery cell units are arranged in a row, and the entire battery 1100 system is composed of a plurality of rows of such battery cell units.

[0103] In each row of battery cell units, a second heat preservation rib 230 is arranged between two adjacent battery cell units, and the heat preservation rib is part of the heat preservation structure 200, which is used to maintain the temperature of the battery cell units stable.

[0104] In addition, between two adjacent rows of battery cell units, the designer ingeniously arranges side liquid cooling plates, which are connected by liquid cooling pipes and arranged in parallel. Such design helps to effectively cool the battery 1100 and ensure that the temperature of the battery 1100 during operation is within a safe range.

[0105] The liquid cooling assembly 400 and the heat preservation structure 200 described above can be staggered. The second heat preservation rib 230 in the heat preservation structure 200 can be provided with a recess groove matched with the liquid cooling assembly 400.

[0106] Referring to Figures 6-8 The fluid channel 410 in the side liquid cooling plate is a U-shaped channel, and a plurality of U-shaped channels are arranged in parallel.

[0107] Each side liquid cooling plate is provided with at least two openings, all of which are on the same side of the side liquid cooling plate. The opening on the upper side is the fluid inlet 420, and the opening on the lower side is the fluid outlet 430; or, the opening on the upper side is the fluid outlet 430, and the opening on the lower side is the fluid inlet 420.

[0108] At least two openings are carefully designed and arranged on each side of the liquid cooling plate, and all of them are located on the same side of the side liquid cooling plate. Specifically, the opening on the upper side is designated as the fluid inlet, and the opening on the lower side is designated as the fluid outlet; of course, this design can also be reversed, that is, the opening on the upper side is designated as the fluid outlet, and the opening on the lower side is designated as the fluid inlet.

[0109] This design ensures that the cooling fluid can flow effectively within the side liquid cooling plate, achieving uniform cooling of the battery cell units. After entering from the inlet, the fluid flows along the U-shaped channel, taking away heat, and then exits from the outlet. In this way, the heat generated by the battery 1100 system during operation can be effectively conducted and dissipated in a timely manner, avoiding local overheating and prolonging the service life and safety of the battery 1100. In addition, this design also allows the fluid to form a good circulation within the liquid cooling plate, further enhancing the cooling effect.

[0110] In a second aspect, referring to Figure 9 The application also provides an electrical equipment 1000, which comprises the above-mentioned battery 1100 and a device main body, and the device main body has an assembly cavity, and the battery 1100 is arranged in the assembly cavity.

[0111] With the above battery 1100, the electrical equipment 1000 can effectively block the loss of heat, ensure that the heat preservation effect of the heat preservation structure 200 is better, simplify the manufacturing process of the battery 1100 and possibly reduce the cost, thereby reducing the manufacturing cost of the electrical equipment 1000.

[0112] Further, in the above structure, the electrical equipment 1000 is composed of several key parts. The device includes a battery 1100, which is a component that provides power. The device also includes a main body part, which has a space called an assembly cavity, and the battery 1100 is installed inside the assembly cavity. In addition, the electrical equipment 1000 also includes several other modules: a driving module 1200, a control module 1300, and tires 1400. The driving module 1200 is responsible for providing power to the device, the battery 1100 can provide energy for the driving module, the control module 1300 is responsible for controlling the operation of the device, and the tires 1400 are the parts that contact the ground when the device moves, ensuring that the device can move stably on various ground surfaces.

[0113] In this application, the driving module 1200 of the electrical equipment 1000 is designed to be efficient and reliable, ensuring that the device can operate stably under various working conditions. The control module 1300 integrates advanced control algorithms, which can accurately respond to operation instructions and monitor and adjust the running state of the device in real time. The tires 1400 part, this application particularly emphasizes its durability and adaptability to adapt to different ground conditions, ensuring the stability and safety of the device. Overall, the electrical equipment 1000 provided in this application embodies innovation and practicality in terms of structural design and functional configuration, aiming to provide users with a more efficient, safer, and more convenient use experience.

[0115] The scheme of the present application aims to solve the problem of the battery 1100 running in a low-temperature environment through a specific design. Specifically, the scheme reduces the temperature drop speed of the battery 1100 in a low-temperature environment by adding thermal insulation materials between the battery 1100 cell and the external box 100. This prevents the battery 1100 cell from being damaged due to excessively low temperature and ensures that the cell can work normally. The side cold plate mentioned in the scheme is an effective thermal management tool that can heat or cool the cell according to the overall temperature requirements of the battery 1100 package. In this way, the battery 1100 cell can be kept within a better working temperature range, which helps to prolong the service life of the cell. The flow channel design of the side cold plate is to reduce the temperature difference of the heat exchange medium in and out, so as to ensure the uniformity of the cell temperature and avoid local overheating or overcooling.
