Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to an energy storage power supply. Background Technology

[0002] With the increasing popularity of portable electronic devices, the demand for portable power banks is growing. Due to their small size and light weight, portable power banks are frequently held or touched during use, making casing temperature control particularly important. Current technology relies primarily on natural heat dissipation for portable power banks; however, the internal components generate significant heat during operation, leading to excessively high casing temperatures and posing a risk of burns to users. Furthermore, the battery module's temperature can reach 60°C during discharge, further exacerbating the heat dissipation problem. Utility Model Content

[0003] The purpose of this invention is to provide an energy storage power supply that can effectively control the internal and external temperatures of a portable power supply, ensuring that the temperature of the external casing remains low even after prolonged operation, thus preventing burns to the user.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model discloses an energy storage power supply, including: a shell, a battery module, the battery module being disposed inside the shell; and a phase change heat insulation component, the phase change heat insulation component being installed inside the shell and covering the battery module, the phase change heat insulation component including a heat-conducting layer, a phase change material layer and a heat insulation layer stacked sequentially from the inside to the outside.

[0006] In some embodiments, the thermally conductive layer abuts against the outer wall of the battery module and is connected by adhesive or snap-fit.

[0007] In some embodiments, the insulation layer abuts against the inner sidewall of the housing and is connected by adhesive or snap-fit.

[0012] In some embodiments, the energy storage power supply further includes a control component, which is installed inside the phase change heat insulation component and electrically connected to the battery module. The control component includes a power board, a control board, a BMS board, and a charging board. The power board, the control board, and the BMS board are arranged sequentially above the battery module, and the charging board is installed below the battery module.

[0014] In some embodiments, the battery module includes an upper support, a lower support, and a plurality of individual batteries, wherein the upper support and the lower support are respectively supported at both ends of the plurality of individual batteries.

[0015] The beneficial effects of this energy storage power supply are as follows: During actual operation, the heat generated by the energy storage power supply is rapidly transferred to the middle phase change material layer through the internal heat-conducting layer. The phase change material layer absorbs heat through phase change, changing from a solid state to a molten state and storing a large amount of heat. The external heat insulation layer prevents the heat from the phase change material layer from being transferred to the outer shell, ensuring that the shell temperature remains within a safe range. This embodiment of the energy storage power supply achieves a comprehensive effect of heat conduction, heat storage, and heat insulation by incorporating a phase change heat insulation component. The temperature of the energy storage power supply is reasonably controlled, ensuring that the shell temperature remains low even after prolonged operation, thus preventing burns to users.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This utility model discloses an energy storage power supply, referenced... Figures 1-3As shown, the energy storage power supply includes a housing 100, a battery module 200, and a phase change thermal insulation component 300. The battery module 200 is disposed inside the housing 100, and the phase change thermal insulation component 300 is installed inside the housing 100 and covers the battery module 200. (Refer to...) Figure 6 As shown, the phase change thermal insulation component 300 includes a heat-conducting layer 310, a phase change material layer 320, and a thermal insulation layer 330 stacked sequentially from the inside out. It can be understood that during actual operation, the heat generated by the energy storage power supply is rapidly transferred through the inner heat-conducting layer 310 to the middle phase change material layer 320. The phase change material layer 320 absorbs heat through phase change, changing from a solid to a molten state and storing a large amount of heat. The outer thermal insulation layer 330 prevents the heat from the phase change material layer 320 from being transferred to the outer casing 100, ensuring that the temperature of the outer casing 100 remains within a safe range. In this embodiment, the energy storage power supply, by incorporating the phase change thermal insulation component 300, achieves a comprehensive effect of heat conduction, heat storage, and heat insulation. The temperature of the energy storage power supply is reasonably controlled, ensuring that the temperature of the outer casing 100 remains low even after prolonged operation, preventing burns to users.

[0033] Optionally, the thermally conductive layer 310, the phase change material layer 320, and the heat insulation layer 330 can be connected by bonding, or by coating the thermally conductive layer 310 with a phase change material to form the phase change material layer 320, and then coating the phase change material layer 320 with a heat insulation material to form the heat insulation layer 330. The connection method of the thermally conductive layer 310, the phase change material layer 320, and the heat insulation layer 330 can be determined according to actual needs, and there is no need to make specific restrictions on the connection method of the thermally conductive layer 310, the phase change material layer 320, and the heat insulation layer 330.

[0034] Optionally, the thermally conductive layer 310 abuts against the outer wall of the battery module 200. It is understood that by directly abutting the outer wall of the battery module 200, the contact area between the thermally conductive layer 310 and the battery module 200 is increased. This allows the heat generated during the operation of the battery module 200 to be quickly transferred through the thermally conductive layer 310 to the phase change material layer 320, which helps control the operating temperature of the battery module 200 and reduces the probability of thermal runaway.

[0035] Optionally, the thermally conductive layer 310 is attached to the outer wall of the battery module 200 by adhesive or snap-fit. The thermally conductive layer 310 can be adhered to the outer wall of the battery module 200 using thermally conductive adhesive, or it can be fixed to the outer wall of the battery module 200 using clips. This ensures a stable connection between the thermally conductive layer 310 and the battery module 200, thereby ensuring a large contact area between the thermally conductive layer 310 and the battery module 200, and ensuring rapid heat transfer. Of course, in other embodiments of this invention, the thermally conductive layer 310 can also be fixed to the outer wall of the battery module 200 using other connection methods as needed, such as screw connections.

[0036] Optionally, the insulation layer 330 abuts against the inner wall of the outer casing 100. It is understood that by abutting against the inner wall of the outer casing 100, the insulation layer 330 can cover the entire inner wall of the outer casing 100, preventing heat from leaking to the outer casing 100 and allowing the outer casing 100 to have a higher temperature.

[0037] Optionally, the heat insulation layer 330 is connected to the inner wall of the outer casing 100 by adhesive or snap-fit. The heat insulation layer 330 can be bonded to the inner wall of the outer casing 100 with high-temperature resistant adhesive, or it can be fixed to the inner wall of the outer casing 100 by snap-fit. This ensures a stable connection between the heat insulation layer 330 and the outer casing 100, thereby ensuring a large contact area between the heat insulation layer 330 and the outer casing 100, and minimizing heat leakage from the phase change material layer 320 to the outer casing 100. Of course, in other embodiments of this invention, the heat insulation layer 330 can also be fixed to the inner wall of the outer casing 100 by other connection methods as needed, such as screw connections.

[0038] Optionally, the thermal conductivity of the thermally conductive layer 310 is 200 W / (m·K)-400 W / (m·K). This ensures that heat can be quickly transferred to the phase change material. Specifically, the thermal conductivity of the thermally conductive layer 310 can be 200 W / (m·K), 210 W / (m·K), 220 W / (m·K), 230 W / (m·K), 240 W / (m·K), 250 W / (m·K), 260 W / (m·K), 270 W / (m·K), 280 W / (m·K), 290 W / (m·K), 300 W / (m·K), 310 W / (m·K), 320 W / (m·K), 330 W / (m·K), 340 W / (m·K), 350 W / (m·K), 360 W / (m·K), 370 W / (m·K), 380 W / (m·K), 390 W / (m·K), or 400 W / (m·K). The thermal conductivity of the thermal conductive layer 310 can also be selected from other values ​​within the range of 200W / (m·K) to 400W / (m·K), or a value outside the above range can be selected according to actual needs.

[0039] Alternatively, the thermally conductive layer 310 can be made of copper foil or aluminum foil. Of course, in other embodiments of this invention, the thermally conductive layer 310 can also be made of other materials as needed.

[0040] Optionally, the phase change material layer 320 has a phase change point of 40℃-50℃. This ensures effective heat absorption within the operating temperature range of the energy storage power supply. Specifically, the phase change point of the phase change material layer 320 can be 40℃, 40.5℃, 41℃, 41.5℃, 42℃, 42.5℃, 43℃, 43.5℃, 44℃, 44.5℃, 45℃, 45.5℃, 46℃, 46.5℃, 47℃, 47.5℃, 48℃, 48.5℃, 49℃, 49.5℃, or 50℃. The phase change point of the phase change material layer 320 can also be selected from other values ​​within the 40℃-50℃ range, or values ​​outside the above range can be selected according to actual needs.

[0041] Optionally, the phase change material layer 320 may be a mixture of paraffin wax or brine. Of course, in other embodiments of this invention, the phase change material layer 320 may be made of other materials as needed.

[0042] It should be noted that the weight of the phase change material layer 320 can be confirmed based on the thermal simulation data of the energy storage power supply, and no specific weight of the phase change material layer 320 is specified here.

[0043] Optionally, the thermal conductivity of the insulation layer 330 is 0.02 W / (m·K) to 0.05 W / (m·K). This ensures that heat transfer to the outer casing 100 is effectively prevented. Specifically, the thermal conductivity of the insulation layer 330 is 0.02 W / (m·K), 0.025 W / (m·K), 0.03 W / (m·K), 0.035 W / (m·K), 0.04 W / (m·K), 0.045 W / (m·K), and 0.05 W / (m·K). The thermal conductivity of the insulation layer 330 can also be selected from other values ​​within the range of 0.02 W / (m·K) to 0.05 W / (m·K), or other values ​​outside the above range can be selected according to actual needs.

[0044] Alternatively, the thermal insulation layer 330 can be made of aerogel or mica sheets. Of course, in other embodiments of the present invention, the phase change material layer 320 can also be made of other materials as needed.

[0045] refer to Figures 3-4 As shown, the outer casing 100 has a first perforation, and the phase change heat insulation component 300 has a second perforation corresponding to the first perforation. The energy storage power supply also includes a lamp panel 400 installed within the first and second perforations. It is understood that the added lamp panel 400 is used to provide lighting functionality for user convenience. The lamp panel 400 can be an LED lamp, or other light-emitting structures can be selected according to actual needs.

[0046] refer to Figure 3As shown, the energy storage power supply also includes a control component 500. The control component 500 is installed inside the phase change heat insulation component 300 and is electrically connected to the battery module 200. The control component 500 includes a power board 510, a control board 520, a BMS (Battery Management System) board 530, and a charging board 540. The power board 510, control board 520, and BMS board 530 are arranged sequentially above the battery module 200, and the charging board 540 is installed below the battery module 200. It is understood that the BMS board 530 monitors the temperature of the battery module 200 in real time to ensure that the temperature of the battery module 200 is between 55℃ and 65℃, avoiding overheating. A temperature sensor can be installed on the control board 520 to monitor the internal temperature of the energy storage power supply in real time, ensuring that the temperature is between 80℃ and 90℃, preventing damage to electronic components. The power board 510 controls the output power. When the temperature sensor detects that the internal temperature of the energy storage power supply exceeds the set threshold, the system automatically reduces the output power or enters protection mode to prevent thermal runaway. The charging board 540 is used to charge the battery module 200 for user convenience.

[0047] It should be further explained that the power board 510, control board 520, BMS board 530, and charging board 540 all generate heat during operation. In this embodiment, the power board 510, control board 520, BMS board 530, and charging board 540 are all installed inside the phase change heat insulation assembly 300. The heat generated by the power board 510, control board 520, BMS board 530, and charging board 540 during operation can also be transferred to the phase change material layer 320 through the heat-conducting layer 310 for storage, thus preventing the working heat of the power board 510, control board 520, BMS board 530, and charging board 540 from being transferred to the outer casing 100.

[0048] Optional, see reference Figure 1 and Figure 3As shown, the housing 100 includes a housing body 110 and a base 120. The housing body 110 defines a mounting cavity with an open lower end. The battery module 200 and the phase change heat insulation component 300 are both disposed within the mounting cavity. The base 120 is mounted on the open end of the housing body 110. Understandably, in the actual installation process, the charging board 540 is mounted on the base 120, and then the battery module 200, power board 510, control board 520, and BMS board 530 are installed sequentially from bottom to top. Next, the phase change heat insulation component 300 is placed over the battery module 200 and the control component 500. Finally, the housing 100 is connected to the base 120. Disassembling the housing 100 into the housing body 110 and the base 120 facilitates assembly and promotes automated assembly. It should be noted that the shell body 110 and the base 120 can be connected by screws, snaps, or other means, depending on the actual needs. No specific connection method between the shell body 110 and the base 120 is specified here.

[0049] Alternatively, the housing 110 may be provided with a rotatable handle 111. Users can lift the entire energy storage power supply using the handle 111, which helps improve user satisfaction.

[0050] Optional, see reference Figure 5 As shown, the battery module 200 includes an upper support 210, a lower support 230, and multiple individual batteries 220. The upper support 210 and the lower support 230 respectively support the two ends of the multiple individual batteries 220. It can be understood that mounting the multiple individual batteries 220 on the upper support 210 and the lower support 230 and fixing the two ends of the individual batteries 220 can ensure the stability of the individual batteries 220, thereby preventing the individual batteries 220 from shaking inside the casing 100 when handling or transporting the energy storage power supply.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
