Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a heat-insulating power generation film, an energy storage system, a vehicle and a carrier. BACKGROUND

[0002] In recent years, in order to pursue better lighting effect and appearance visual effect, a large sunroof or panoramic sunroof design gradually appears in the carrier. For example, a car with a large sunroof, a yacht with a panoramic sunroof, etc. However, although the panoramic sunroof design realizes the excellent lighting effect and appearance visual effect of the carrier, in a strong light environment, the temperature inside the carrier is easily increased, which causes the discomfort of the people inside the carrier, and the existing carrier sunroof function is single and cannot realize the full use of the carrier assembly space. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a heat-insulating power generation film, an energy storage system, a vehicle and a carrier to solve the technical problem that the temperature inside the existing carrier is easily increased due to the sunroof design and the carrier space cannot be fully utilized.

[0004] An embodiment of the present application provides a heat-insulating power generation film. The heat-insulating power generation film is applied to a carrier. The carrier includes a light-transmitting area. The heat-insulating power generation film includes a heat-insulating film sheet and a connecting piece. The heat-insulating film sheet is configured to be flexible and deformable, and is used to convert light energy into electric energy and transmit the electric energy to an electric device. The connecting piece is arranged on the heat-insulating film sheet, and is configured to be connected with the carrier, so that the orthographic projection of the heat-insulating film sheet at least partially covers the light-transmitting area. The connecting piece is also configured to form a heat-insulating space between the heat-insulating film sheet and the part of the carrier having the light-transmitting area.

[0005] In the heat-insulating power generation film, when light irradiates on the heat-insulating power generation film, the heat-insulating film sheet can reflect the light and absorb solar energy, convert the solar energy into electric energy, and transmit the electric energy to the electric device. At the same time, the heat-insulating space can absorb a part of heat energy converted from the light not reflected by the heat-insulating film sheet. Therefore, not only the light-transmitting area in the carrier can be shaded, which is beneficial to reduce the heat transferred to the inside of the carrier and lower the temperature inside the carrier, but also the solar energy can be effectively utilized to convert into electric energy.

[0006] In some embodiments of the present application, the connecting piece is an adhesive tape, which is attached to the heat-insulating film sheet and forms the heat-insulating space together with the heat-insulating film sheet. The adhesive tape is configured to be attached to the carrier.

[0007] The skilled person only needs to attach the adhesive tape to the heat-insulating film sheet and attach the heat-insulating film sheet to the carrier through the adhesive tape, which is not only simple and convenient to operate and reduces the installation difficulty, but also the adhesive tape is low in price and is beneficial to reduce the cost.

[0008] In some embodiments of this application, the connector is a magnetic element, which is disposed on the heat-insulating diaphragm and together with the heat-insulating diaphragm forms a heat-insulating space. The magnetic element is configured to magnetically connect with the carrier.

[0009] The magnetic attachment facilitates the installation and removal of the heat-insulating and power-generating film, meeting the needs of different environments. In environments with strong external sunlight, technicians can use the magnetic attachment to install the heat-insulating and power-generating film onto the vehicle to block light and reduce the internal temperature of the vehicle. In environments with weak external sunlight, technicians can remove the heat-insulating and power-generating film from the vehicle to enhance the brightness inside the vehicle.

[0010] In some embodiments of this application, the connector is a flexible bracket with a mounting through hole. A heat-insulating diaphragm is installed within the mounting through hole, and the hole wall and the heat-insulating diaphragm together form a heat-insulating space. The flexible bracket is configured to be detachably connected to the carrier.

[0011] By installing the heat-insulating film within the through-holes of the flexible support, the heat-insulating film can be protected, extending its service life. When the vehicle is impacted or bumped, the flexible support can withstand some of the impact force, thus acting as a buffer and reducing the risk of the heat-insulating film breaking or being damaged due to excessive external force.

[0012] In some embodiments of this application, the heat-insulating film is located on the outside of the carrier.

[0013] Because the heat-insulating film is located on the outside of the vehicle, it can preferentially reflect most of the light. The remaining unreflected light is then converted into heat, and some of it is absorbed by the insulated space. Finally, the remaining heat is transferred to the interior of the vehicle, which helps to improve the heat insulation effect of the insulated space and reduce the temperature inside the vehicle.

[0014] In some embodiments of this application, the connectors are arranged along the outline edge of the orthographic projection of the heat insulation film.

[0015] By arranging connectors along the contour edge of the orthographic projection of the thermal insulation film, not only can the thermal insulation space be maximized, thus improving the thermal insulation effect and reducing the temperature inside the carrier, but it also helps to improve the stability of the thermal insulation and power generation film installation and reduces the risk of the thermal insulation and power generation film falling off the carrier. For example, if the carrier moves too fast, the airflow flowing from both sides of the connectors and the resulting lift force can lift the thermal insulation and power generation film.

[0016] In some embodiments of this application, the heat-insulating power generation film further includes a flexible support member, which is installed in the heat-insulating space, with one side of the flexible support member abutting against the heat-insulating film and the other side abutting against the carrier.

[0017] By setting up flexible support components to support the heat insulation film, the risk of shrinkage of the heat insulation space due to the collapse of the heat insulation film is reduced, ensuring that the heat insulation effect of the heat insulation space is always in the best condition.

[0018] In some embodiments of this application, the heat-insulating power-generating film further includes a light reflector, which is mounted on the heat-insulating film and / or a carrier within the heat-insulating space.

[0019] When light shines on the heat-insulating and power-generating film, both the heat-insulating film and the light reflector can reflect the light, which helps to improve the reflectivity of the heat-insulating and power-generating film to light, thereby reducing the conversion of light into heat energy and better reducing the heat transferred to the interior of the vehicle, thus lowering the temperature inside the vehicle.

[0020] In some embodiments of this application, the thermal insulation space is configured as a negative pressure chamber.

[0021] By constructing the insulation space as a negative pressure chamber, the amount of air in the insulation space is reduced, which helps to reduce the transfer of heat from the air to the vehicle, thereby improving the insulation effect of the insulation space.

[0022] In some embodiments of this application, the height of the heat insulation space is 0.8mm-1.5mm along the orthogonal projection direction of the heat insulation film.

[0023] By limiting the height of the insulation space to 0.8mm-1.5mm, it is beneficial to reduce the overall wind resistance of the heat insulation and power generation film while ensuring that the insulation space has a better insulation effect. This reduces the risk of the heat insulation and power generation film falling off and improves the stability and installability of the heat insulation and power generation film.

[0024] One embodiment of this application provides an energy storage system. The energy storage system includes an energy storage device and a thermally insulating and power-generating membrane as described in any of the above embodiments. The energy storage device and the thermally insulating and power-generating membrane are electrically connected.

[0025] In the aforementioned energy storage system, the heat-insulating power generation film can not only convert solar energy into electrical energy and transmit the electrical energy to the energy storage device for subsequent use by users; at the same time, it can also block light from the light-transmitting areas in the vehicle and absorb some heat through the heat-insulating space, thereby reducing the temperature inside the vehicle.

[0026] One embodiment of this application provides a vehicle. The vehicle includes a vehicle body and an energy storage system as described above. The energy storage device is installed inside the vehicle body, and a heat-insulating and power-generating film is installed on the top of the vehicle body.

[0027] In the aforementioned vehicles, the heat-insulating and power-generating film can not only convert solar energy into electrical energy and transmit the electrical energy to the energy storage device for subsequent use by users, effectively utilizing the top space of the vehicle body; at the same time, it can also block light from the light-transmitting areas of the vehicle and absorb some heat through the heat-insulating space, thereby reducing the temperature inside the vehicle.

[0028] One embodiment of this application provides a carrier. The carrier includes a carrier body and an energy storage system as described above. The energy storage device is installed inside the carrier body, and a thermally insulating power generation membrane is installed on the top of the carrier body.

[0029] In the aforementioned vehicle, the heat-insulating power-generating film can not only convert solar energy into electrical energy and transmit the electrical energy to the energy storage device for subsequent use by users, effectively utilizing the top space of the vehicle body; at the same time, it can also block light from the light-transmitting areas in the vehicle and absorb some heat through the heat-insulating space, thereby reducing the temperature inside the vehicle.

[0041] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0044] In recent years, in pursuit of better lighting and visual appeal, large sunroofs or panoramic sunroofs have gradually appeared in vehicle designs. Examples include cars with large sunroofs and yachts with panoramic sunroofs. However, while panoramic sunroofs achieve excellent lighting and visual appeal, they can also cause the interior temperature to rise in bright sunlight, leading to discomfort for occupants. Furthermore, existing vehicle sunroofs have limited functionality and fail to fully utilize the vehicle's interior space.

[0045] One embodiment of this application provides a heat-insulating and power-generating film. The heat-insulating and power-generating film is applied to a carrier. The carrier includes a light-transmitting area. The heat-insulating film is configured to be flexibly deformable and for converting light energy into electrical energy and transmitting the electrical energy to electrical equipment. A connector is disposed on the heat-insulating film and configured to connect to the carrier such that the orthographic projection of the heat-insulating film at least partially covers the light-transmitting area. The connector is also configured to form a heat-insulating space between the heat-insulating film and the portion of the carrier having the light-transmitting area.

[0046] In the aforementioned heat-insulating and power-generating film, when light shines on it, the film reflects the light and absorbs solar energy, converting it into electrical energy, which is then transmitted to the electrical equipment. Simultaneously, the insulated space absorbs some of the heat energy converted from light not reflected by the film. Therefore, it not only effectively blocks light from the translucent areas of the vehicle, reducing heat transfer to the interior and lowering the internal temperature, but also efficiently utilizes the vehicle space to convert solar energy into electricity.

[0047] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] One embodiment of this application provides a heat-insulating and power-generating film 10. The heat-insulating and power-generating film 10 is applied to a vehicle 2. The vehicle 2 can be a vehicle 1, a yacht, or other transportation equipment that carries people or goods.

[0049] In some embodiments, the vehicle 2 includes a light-transmitting area 300, through which external light can pass and enter the interior of the vehicle 2, which is beneficial to achieving better lighting effect inside the vehicle 2 and better visual appearance.

[0050] For example, the light-transmitting area 300 can be the sunroof of vehicle 1, the rear window of vehicle 1, or a window of a yacht. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0051] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the heat-insulating power-generating film 10 includes a heat-insulating film 11 and a connector 12. The heat-insulating film 11 is configured to be flexibly deformable and is used to convert light energy into electrical energy and transmit the electrical energy to an electrical device (not shown). The electrical device may be a video player, a refrigerator, or a power bank installed inside the carrier 2, etc.

[0052] By constructing the heat insulation film 11 as flexible and deformable, firstly, it is beneficial for the heat insulation film 11 to bend and adapt to the shape of the top of the carrier 2, thereby improving the adhesion between the heat insulation and power generation film 10 and the carrier 2; secondly, it is beneficial for the heat insulation and power generation film 10 to adapt to different types or models of carriers 2, thereby improving the versatility of the heat insulation and power generation film 10.

[0053] In some embodiments, the heat-insulating film 11 is a flexible solar panel. The flexible solar panel includes a flexible substrate (not shown) and a battery cell module (not shown) disposed thereon, the battery cell module being able to absorb light energy and convert it into electrical energy. In other embodiments, the heat-insulating film 11 can be other structures, which are not limited in this application.

[0054] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the connector 12 is disposed on the heat-insulating film 11 and is configured to connect to the carrier 2 such that the orthographic projection of the heat-insulating film 11 at least partially covers the light-transmitting area 300. In other words, the heat-insulating film 11 is attached to the carrier 2 via the connector 12, and the orthographic projection of the heat-insulating film 11 at least partially covers the light-transmitting area 300.

[0055] Understandably, when light shines on the heat-insulating and power-generating film 10, the heat-insulating film 11 can partially reflect the light shining into the light-transmitting area 300 to block the light from the vehicle 2, thereby reducing the temperature inside the vehicle 2. At the same time, the heat-insulating film 11 can also absorb some light and convert it into electrical energy, which is then supplied to electrical devices to power and charge in-vehicle electrical devices (such as refrigerators, air conditioners, and power banks).

[0056] For example, the heat insulation film 11 is attached to the top of the vehicle 1 via the connector 12, that is, to the roof (top of the vehicle 2). The orthographic projection of the heat insulation film 11 at least partially covers the sunroof on the top of the vehicle 1.

[0057] It should be noted that the top of vehicle 1 usually refers to the position on the side away from the ground between the front and rear windshields and between the left and right doors.

[0058] It is worth noting that this application does not limit the installation sequence of the heat insulation film 11 and the connector 12.

[0059] In some embodiments, a technician may first install the connector 12 onto the heat insulation film 11, and then install the heat insulation film 11 with the connector 12 onto the carrier 2.

[0060] In some embodiments, a technician may first install the connector 12 onto the carrier 2, and then connect the heat insulation film 11 to the connector.

[0061] Please see Figure 1 In some embodiments, the connector 12 is also configured to form a heat-insulating space 13 between the heat-insulating film 11 and the portion of the carrier 2 having a light-transmitting area 300. Understandably, when light shines on the heat-insulating and power-generating film 10, the heat-insulating film 11 can reflect most of the light, while the light not reflected by the heat-insulating film 11 will be converted into heat energy.

[0062] The heat energy converted from light that is not reflected by the heat insulation film 11 is partially absorbed by the heat insulation space 13, and the remaining heat energy is eventually transferred to the interior of the vehicle 2. The heat insulation space 13 helps to reduce the heat transferred to the interior of the vehicle 2, thereby better reducing the temperature inside the vehicle 2.

[0063] The heat-insulating and power-generating film 10 provided in this application can not only block the light-transmitting area 300 in the carrier 2, which helps to reduce the heat transferred to the interior of the carrier 2 and lower the temperature inside the carrier 2, but also effectively utilize the space of the carrier 2 to convert solar energy into electrical energy.

[0064] In some embodiments, the connector 12 is an adhesive strip, which is attached to the heat insulation film 11 and together with the heat insulation film 11 forms a heat insulation space 13. The adhesive strip is configured to be bonded to the carrier 2.

[0065] Using adhesive strips as connectors 12 reduces the difficulty of installing the heat-insulating and power-generating film 10, making the operation simple and convenient. Furthermore, the adhesive strips are inexpensive, which helps reduce costs.

[0066] For example, the adhesive strip is a 3M adhesive strip. The 3M adhesive strip is attached to the heat insulation film 11 and surrounds it to form a heat insulation space 13. The heat insulation film 11 is bonded to the carrier 2 by the 3M adhesive strip.

[0067] In other embodiments, the adhesive strip may also be a double-sided adhesive strip or other adhesive strips, and this application does not limit this to any particular type.

[0068] It is worth noting that in order to improve the bonding stability of the heat insulation and power generation film 10, before pasting the heat insulation and power generation film 10 onto the carrier 2, it is necessary to ensure that the bonding area of ​​the carrier 2 is clean, dry, and free of a large amount of contaminants, such as dust and fallen leaves.

[0069] In some embodiments, the connector 12 is a magnetic connector. The magnetic connector is disposed on the heat insulation film 11 and together with the heat insulation film 11 forms the heat insulation space 13. The magnetic connector is configured to magnetically connect with the carrier 2. The magnetic connector facilitates the installation and removal of the heat insulation and power generation film 10, meeting the needs of different environments.

[0070] Understandably, when in a brightly lit environment, technicians can use magnetic attachments to install the heat-insulating and power-generating film 10 onto the carrier 2 to block light and reduce the temperature inside the carrier 2. When in a dimly lit environment, technicians can remove the heat-insulating and power-generating film 10 from the carrier 2 to enhance the brightness inside the carrier 2 and meet the lighting requirements inside the carrier 2.

[0071] For example, the connector 12 is a magnetic strip, which is installed on the heat insulation film 11 and surrounds it to form a heat insulation space 13. The heat insulation film 11 is attracted to the carrier 2 by the magnetic strip.

[0072] In other embodiments, the magnetic attractor may also be a magnetic metal strip or other magnetic attractor, and this application does not limit this to any particular type.

[0073] Please see Figure 3 In some embodiments, the connector 12 is a flexible support 14, which has a mounting through hole 141. The heat insulation film 11 is installed in the mounting through hole 141, and the hole wall of the mounting through hole 141 and the heat insulation film 11 together form a heat insulation space 13. The flexible support 14 is configured to be detachably connected to the carrier 2.

[0074] When the carrier 2 is impacted or bumped, the flexible support 14 can withstand part of the impact force, thus playing a buffering role and reducing the risk of the heat insulation film 11 breaking or being damaged due to excessive external force. By installing the heat insulation film 11 in the through hole of the flexible support 14, it is beneficial to protect the heat insulation film 11 and extend the service life of the heat insulation and power generation film 10.

[0075] For example, the flexible support 14 is a rubber collar, the heat insulation film 11 is installed on the rubber collar, and the inner ring wall of the rubber collar and the heat insulation film 11 together form a heat insulation space 13. The rubber collar can be detachably installed on the carrier 2.

[0076] In other embodiments, the flexible support 14 may also be other flexible supports 14 such as silicone rings, and this application does not limit it.

[0077] Please see Figure 4 In some embodiments, the heat insulation film 11 is located on the inner side of the carrier 2 (specifically, the inner wall of the carrier 2, such as the inner wall of a sunroof). By placing the heat insulation film 11 on the inner side of the carrier 2, it is beneficial to reduce the risk of damage to the heat insulation film 11 due to external forces, thereby protecting the heat insulation film 11 and improving the service life of the heat insulation and power generation film 10.

[0078] Understandably, when light shines on the heat-insulating and power-generating film 10, the light passes sequentially through the light-transmitting area 300 and the heat-insulating space 13, and then shines onto the heat-insulating film 11. The heat-insulating film 11 reflects the light and converts solar energy into electrical energy, which is then transmitted to the electrical equipment. The heat-insulating space 13 absorbs a portion of the heat converted from the unreflected light.

[0079] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the heat-insulating film 11 is located on the outside of the vehicle 2 (specifically, the outer wall of the vehicle 2, such as the outer wall of the roof). By placing the heat-insulating film 11 on the outside of the vehicle 2, it can preferentially reflect most of the light. The remaining unreflected light is then converted into heat, and a portion of it is absorbed by the heat-insulating space 13. Finally, the remaining heat is transferred to the interior of the vehicle 2, which helps to better improve the heat insulation effect of the heat-insulating space 13 and reduce the temperature inside the vehicle 2.

[0080] In some embodiments, the connector 12 is arranged along the outline edge of the orthographic projection of the heat insulation film 11. By arranging the connector 12 along the outline edge of the orthographic projection of the heat insulation film 11, not only can the heat insulation space 13 be maximized, thus improving the heat insulation effect and reducing the temperature inside the carrier 2, but it also helps to improve the stability of the heat insulation and power generation film 10 installation and reduces the risk of the heat insulation and power generation film 10 falling off the carrier 2. For example, if the carrier 2 moves too fast, the airflow flows from both sides of the connector 12, and the resulting upward force lifts the heat insulation and power generation film 10.

[0081] In other embodiments, the connector 12 may not be arranged along the outline edge of the orthographic projection of the heat insulation film 11. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0082] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the heat-insulating power generation film 10 further includes a flexible support member 15, which is installed in the heat-insulating space 13, with one side of the flexible support member 15 abutting against the heat-insulating film 11 and the other side abutting against the carrier 2.

[0083] Understandably, when the heat insulation film 11 tends to collapse towards the vehicle 2 under the action of external force (such as wind pressure), the flexible support 15 can support the heat insulation film 11, hinder the movement of the heat insulation film 11, that is, prevent the heat insulation film 11 from collapsing.

[0084] It should be noted that by setting up a flexible support 15 to support the heat insulation film 11, it is beneficial to reduce the risk of shrinkage of the heat insulation space 13 due to the collapse of the heat insulation film 11, and ensure that the heat insulation effect of the heat insulation space 13 is always in a better state.

[0085] For example, the flexible support 15 is a 3M adhesive strip, with both ends of the 3M adhesive strip bonded to the heat insulation film 11 and the carrier 2, respectively. In other embodiments, the flexible support 15 may also be a rubber strip, etc., and this application does not limit it to this.

[0086] In some embodiments, the heat-insulating and power-generating film 10 further includes a light reflector 16, such as aluminum foil or tin foil. When light shines on the heat-insulating and power-generating film 10, both the heat-insulating film 11 and the light reflector 16 can reflect the light, which helps to improve the reflectivity of the heat-insulating and power-generating film 10 to light, thereby reducing the conversion of light into heat energy and further reducing the heat transferred to the interior of the carrier 2, thereby reducing the temperature inside the carrier 2.

[0087] In some embodiments, a light reflector 16 is mounted on a heat-insulating film 11 within the heat-insulating space 13. By mounting the light reflector 16 on the heat-insulating film 11, it is beneficial to achieve the integration of the heat-insulating power-generating film 10 and improve the assembly efficiency of the heat-insulating power-generating film 10 on the carrier 2.

[0088] In some embodiments, a light reflector 16 is mounted on a carrier 2 within the heat-insulating space 13. By mounting the light reflector 16 on the carrier 2, technicians can mount the light reflector 16 on the carrier 2 while mounting the connector 12 on the heat-insulating film 11, which helps to shorten the assembly time between the heat-insulating power-generating film 10 and the carrier 2.

[0089] In some embodiments, light reflectors 16 are mounted on the heat insulation film 11 and the carrier 2 within the heat insulation space 13. Since both the heat insulation film 11 and the carrier 2 are equipped with light reflectors 16, the heat insulation film 11, the light reflectors 16 on the heat insulation film 11, and the light reflectors 16 on the carrier 2 can all reflect light, which helps to better improve the reflectivity of the heat insulation and power generation film 10 to light, thereby reducing the conversion of light heat energy and further reducing the heat transferred to the interior of the carrier 2.

[0090] In some embodiments, the heat insulation space 13 is configured as a negative pressure chamber. For example, after the heat insulation film 11 is installed on the carrier 2 via the connector 12, a technician uses an air pump to extract the gas in the heat insulation space 13 to create a negative pressure state, that is, the heat insulation space 13 is a negative pressure chamber.

[0091] By constructing the heat insulation space 13 as a negative pressure chamber, the amount of air in the heat insulation space 13 is reduced, which helps to reduce the transfer of heat by the air, that is, to reduce the transfer of heat to the carrier 2, thereby improving the heat insulation effect of the heat insulation space 13.

[0092] In some embodiments, the height of the heat insulation space 13 along the orthogonal projection direction of the heat insulation film 11 is 0.8mm-1.5mm. By limiting the height of the heat insulation space 13 to 0.8mm-1.5mm, it is beneficial to reduce the overall wind resistance of the heat insulation and power generation film 10 while ensuring that the heat insulation space 13 has a better heat insulation effect, thereby reducing the risk of the heat insulation and power generation film 10 falling off and improving the stability and installability of the heat insulation and power generation film 10.

[0093] Optionally, the height of the heat insulation space 13 is 1.2mm, which helps to reduce the overall wind resistance of the heat insulation and power generation film 10 while ensuring that the heat insulation space 13 has a better heat insulation effect. That is, it takes into account both the wind resistance of the heat insulation and power generation film 10 and the cooling effect of the heat insulation space 13.

[0094] In other embodiments, the height of the heat insulation space 13 may also be other values ​​such as 0.9mm, 1.0mm or 1.4mm. This application does not limit this value, and those skilled in the art can choose according to the actual situation.

[0095] Please see Figure 5 One embodiment of this application provides an energy storage system 100. The energy storage system 100 includes an energy storage device 20 and a thermal insulation and power generation membrane 10 as described in any of the above embodiments, wherein the energy storage device 20 and the thermal insulation and power generation membrane 10 are electrically connected.

[0096] The energy storage device 20 has the functions of storing and discharging electricity. The energy storage device 20 includes a power conversion module (not shown). The power conversion module is housed within a housing (not shown). The housing protects the power conversion module.

[0097] The power conversion module is electrically connected to the battery pack. The power conversion module is used to control the AC / DC conversion of the battery pack's output current. An energy storage device 20 equipped with a power conversion module can be a small portable power bank, etc.
