[0056] [20 battery cells]

[0057] In a first embodiment of the battery cell 20, the battery cell 20 is implemented as a battery pack 20A, which preferably refers to the prior patent CN214848865U.

[0058] The battery pack 20A can supply power to the first electricity-using equipment 31 separately from the energy storage power source 10. A single battery pack 20A may supply power to the first electricity-using equipment 31, or multiple battery packs 20A may supply power to the first electricity-using equipment 31 simultaneously. The first electricity-using equipment 31 is usually provided with a dedicated space to accommodate the battery pack 20A, and the battery pack 20A is adapted to be attached to the first electricity-using equipment 31 and supply power directly thereto. The battery pack 20A differs from a mobile power source that cannot supply power directly to the electricity-using equipment and usually requires an adapter cable to achieve electrical connection with the electricity-using equipment. However, the battery pack 20A is a power source compatible with the first electricity-using equipment 31 and can supply power directly to the first electricity-using equipment 31 without the need for an adapter cable.

[0059] In some preferred embodiments, the battery pack 20A includes a charge / discharge connection unit that can cooperate with the charging unit 15 to charge the battery pack 20A from the energy storage power source 10, and the charge / discharge connection unit can also cooperate with the first electricity-consuming device 31 to supply power to the first electricity-consuming device 31 from the battery pack 20A. In other words, the battery pack 20A can be both charged and discharged via the charge / discharge connection unit, which is advantageous for simplifying the overall structure of the battery pack 20A.

[0060] Furthermore, the charging / discharging connection unit includes a plurality of second connection terminals, and the battery pack 20A is electrically connected to each of the first connection terminals 151 of the charging unit 15 via the second connection terminals, so that the battery pack 20A is electrically connected to the energy storage power source 10 by a cordless coupling. The battery pack 20A is adapted to be electrically connected to the first electricity-using equipment 31 by a cordless coupling via each of the second connection terminals, i.e., the battery pack 20A supplies power to the first electricity-using equipment 31 cordlessly.

[0061] Furthermore, the charge / discharge connection portion includes three second connection terminals spaced apart from each other. The provision of the three second connection terminals allows transmission of different types of electrical signals, and typically the multiple second connection terminals must include at least a positive connection terminal and a negative connection terminal. The third second connection terminal provides the possibility of establishing a communication connection between the energy storage power source 10 and the battery pack 20A.

[0062] Preferably, the plurality of second connection terminals include a second positive terminal and a second negative terminal, which are electrically connected to the first positive terminal and the first negative terminal of the charging unit 15, respectively.

[0063] Preferably, the plurality of second connection terminals includes a second communication terminal, the second communication terminal adapted to be communicatively connected to the first communication terminal in the charging unit 15, and the energy storage power source 10 adapted to controllably supply power to the battery pack 20A based on a communication code transmitted from the second communication terminal.

[0064] In the second embodiment of the battery cell 20, the battery cell 20 is an integrated pack 20B, which includes a mounting box 21 and a plurality of battery packs 20A removably mounted in the mounting box 21. For the battery pack 20A, refer to the previous embodiment.

[0065] The energy storage power source 10 is adapted to power the integrated pack 20B, and when the integrated pack 20B is powered, it also simultaneously powers each of the battery packs 20A provided in the mounting box 21. The multiple battery packs 20A in the integrated pack 20B may be the same or different.

[0066] The shape of the integrated pack 20B makes it possible to easily charge a larger number of battery packs 20A, and when the multiple battery packs 20A are removed from the energy storage power source 10, they can be stored in the mounting box 21, thereby solving the problem of storage after the multiple battery packs 20A are separated from the energy storage power source 10.

[0067] The mounting box 21 has a plurality of charging compartments 211 for detachably storing the battery packs 20A, and the charging compartments 211 have openings. When the integrated bag 20B is placed in the storage section 142, the openings of each charging compartment 211 communicate with the outside through the openings 1420 of the storage section 142. Therefore, even when the integrated bag 20B is placed in the storage section 142, the user can directly remove the battery pack 20A from the charging compartment 211 or directly insert the battery pack 20A into the charging compartment 211.

[0068] Preferably, the integrated pack 20B includes two or more battery packs 20A, and accordingly, the mounting box 21 has two or more charging compartments 211. More preferably, the integrated pack 20B includes three or more battery packs 20A, and accordingly, the mounting box 21 has three or more charging compartments 211. Even more preferably, the integrated pack 20B includes four or more battery packs 20A, and accordingly, the mounting box 21 has four or more charging compartments 211. Even more preferably, the multiple charging compartments 211 are arranged in a substantially straight line in the mounting box 21.

[0069] In some preferred embodiments, the integrated pack 20B includes a general electrical connection that can cooperate with the charging unit 15 to enable the energy storage power source 10 to supply power to the integrated pack 20B. In some embodiments, the general electrical connection can also cooperate with the first electrical usage device 31 to enable the integrated pack 20B to supply power to the first electrical usage device 31.

[0070] Preferably, the overall electrical connection of the integrated pack 20B is provided in the mounting box 21 so that the overall electrical connection can be electrically connected to the charging section 15 when the mounting box is provided in the housing section 142.

[0071] Furthermore, a support electrical connection is provided in each charging compartment 211, and all of the support electrical connections in each charging compartment 211 are electrically connected to the general electrical connection, and the charging and discharging connections of the battery pack 20A are adapted to be electrically connected to each support electrical connection, so that the battery pack 20A provided in each charging compartment 210 can be electrically connected to the energy storage power source 10 through the support electrical connection and the general electrical connection.

[0072] In some embodiments, the integrated pack 20B further comprises a control circuit and an output port, the control circuit adapted to electrically connect to at least one battery pack 20A disposed within the charging compartment 211, and the control circuit also electrically connected to the output port such that the integrated pack 20B can power other electrical usage equipment via the output port.

[0073] [Housing 14]

[0074] In the first embodiment of the housing 14, the main body of the accommodating portion 142 is fixedly or removably provided inside the housing main body 141, i.e., the main body of the accommodating portion 142 is provided in the storage space of the housing main body 141, and the opening of the accommodating portion 142 is formed on the surface of the housing main body 141.

[0075] In some embodiments, the opening 1420 of the receiving portion 142 is located on one surface of the housing body 141 , for example, the first side surface 1413 or the top surface 1411 .

[0076] In some other embodiments, the opening 1420 of the receptacle 142 is located on at least two sides of the housing body 141. For example, the opening 1420 extends from the first side 1413 to the top surface 1411, or the opening 1420 extends from the first side 1413 to the second side 1412.

[0077] In some embodiments, the housing 14 includes at least two storage compartments 142, and the two storage compartments 142 are adapted to detachably store the same battery cells 20, so that when the power of one battery cell 20 is exhausted, the other battery cell 20 can be used to continue to supply power to the first electricity-using device 31. Note that the term "same battery cells 20" used in this application refers to two battery cells 20 that interchangeably supply power to the first electricity-using device 31, and typically have the same size and the same charge / discharge voltage.

[0078] The energy storage power source 10 can store and charge at least two battery cells 20 of the first electricity-using device 31, i.e., can store and charge at least one spare battery cell 20. As a result, when the power of one battery cell 20 of the first electricity-using device 31 is used up, the spare battery cell 20 can be quickly replaced to ensure continuous use of the first electricity-using device 31, effectively solving the problem of limited use range of the first electricity-using device 31 due to unreliable power supply. In other words, when the power of one battery cell 20 installed in the first electricity-using device 31 is used up, the battery cell 20 can be removed and directly installed in the energy storage power source 10 for charging, and the spare battery cell 20 can be attached to the first electricity-using device 31 to enable continuous operation of the first electricity-using device 31.

[0079] In a preferred embodiment, the plurality of receiving sections 142 are arranged in sequence in the height direction of the housing body 141, and the directions of the openings 1420 of the plurality of receiving sections 142 are aligned.

[0080] In the second embodiment of the housing 14, the accommodating portion 142 is fixedly or detachably provided to the housing main body 141, i.e., the accommodating portion 142 is not housed in the housing main body 141. For example, the accommodating portion 142 may be provided on the top surface 1411 of the housing main body 141 or on a certain side surface of the housing main body 141.

[0083] [Procurement Department 142]

[0084] In the first embodiment of the storage section 142, the inner wall of the storage section 142 restricts the position of the battery cell 20 in the circumferential direction, allowing the battery cell 20 to move freely only in the first axial direction, that is, the direction extending from the opening 1420 of the storage section 142 to its bottom surface. The charging section 15 is provided on the bottom surface of the holding section 142 so that when the battery cell 20 moves along the first axial direction to the bottom surface of the storage section 142, it connects to the charging section 15 and starts charging.

[0085] In some embodiments, the opening 1420 of the housing 142 is perpendicular to the first axis.

[0086] In some embodiments, the housing 14 further includes an ejection mechanism (not shown) that is provided within the receptacle 142 and is used to retain the battery cell 20 within the receptacle 142 or to separate the battery cell 20 from the receptacle 142.

In other words, the ejection mechanism is provided in the accommodating section 142 toward the opening 1420, and after the battery cell 20 is attached to the accommodating section 142 from the opening 1420, the ejection mechanism can be switched between the locked state and the ejected state by pushing it straight in.

[0088] Transformably, the ejection mechanism is movably provided on the side wall of the accommodating portion 142, and the ejection mechanism is arranged to switch from a storage position to a release position when pressed, and when the ejection mechanism is in the release position, it does not protrude from the inner wall of the accommodating portion 142, and when the ejection mechanism is in the storage position, it protrudes from the inner wall of the accommodating portion 142 and is adapted to fit into a slot on the side of the battery cell 20 to lock the position of the battery cell 20.

[0089] In a second embodiment of the accommodating section 142, the inner wall of the accommodating section 142 confines the position of the battery cell 20 laterally while allowing the battery cell 20 to move freely in at least a first axial direction and a second axial direction, which are not parallel to each other. At least a portion of the opening 1420 is perpendicular to the first axial direction, and at least another portion is perpendicular to the second axial direction, so that the battery cell 20 may enter and exit the accommodating section 142 along the first axial direction or along the second axial direction. Preferably, the first axial direction and the second axial direction are perpendicular to each other.

[0090] In one specific embodiment, the opening 1420 of the housing 142 is L-shaped, and the battery cell 20 is movable in a first axis direction and a second axis direction that are perpendicular to each other. The charging part 15 may be provided on the bottom surface of the housing 142 along the first axis direction, or on the bottom surface of the housing 142 along the second axis direction. Preferably, an ejection mechanism is provided within the housing 142, but this ejection mechanism can be described above and will not be further described here.

The charging section 15 is provided on the bottom surface of the storage section 142 along the second axis direction.

[0092] In yet another embodiment, the accommodating portion 142 is planar, i.e., the opening 1420 of the accommodating portion 142 is open, and the battery cell 20 is restricted in position only in the plane where the accommodating portion 142 is located, but can move freely in all other directions. For example, the accommodating portion 142 may be provided on the top surface of the housing body 141.

[0093] [Charging part 15]

[0094] In the first embodiment of the charging unit 15, the charging unit 15 is electrically connected to the battery cell 20 and charged.

[0095] In some embodiments, the charging unit 15 includes a plurality of first connection terminals 151, and the battery cells 20 are adapted to be electrically connected to the respective first connection terminals 151 of the charging unit 15. When the battery cells 20 are provided in the accommodating portion 142, cordless coupling with the energy storage power supply 10 can be achieved by connection with the respective first connection terminals 151, which is advantageous in simplifying the structure of the energy storage power supply 10.

[0096] In one specific embodiment, the first connection terminal 151 is implemented as a needle-shaped or column-shaped connection terminal, so that the first connection terminal can be easily inserted into a corresponding terminal on a battery cell.

[0097] In some embodiments, each first connection terminal 151 extends from the bottom of the accommodating portion 142 to the opening 1420 independently of each other, and the inner wall of the accommodating portion 142 restricts the battery cell 20 in the circumferential direction, allowing the battery cell 20 to move only in the first axial direction. When the battery cell 20 is inserted inward from the opening 1420 to the bottom of the accommodating portion 142, it is connected exactly to each first connection terminal 151 located at the bottom of the accommodating portion 142, so that it is possible to ensure that the battery cell 20 is electrically connected to the charging portion 15 without any problems and that the battery cell 20 is fully accommodated in the accommodating portion 142 during charging.

[0098] In some embodiments, the charging unit 15 has three first connection terminals 151 spaced apart from one another within the accommodating portion 142, and by providing three first connection terminals 151, transmission of different types of electrical signals can be realized. Typically, the multiple first connection terminals 151 must include at least a positive connection terminal and a negative connection terminal, and the charging unit 15 of the present invention further adds terminals for making electrical connections to enable communication connection between the energy storage power source 10 and the battery cell 20.

[0099] Furthermore, the multiple first connection terminals 151 include a first positive terminal and a first negative terminal that are electrically connected to a second positive terminal and a second negative terminal on the battery cell 20, respectively, thereby realizing electrical connection between the charging unit 15 and the battery cell 20.

[0100] Furthermore, the plurality of first connection terminals 151 includes a first communication terminal that communicatively connects with a second communication terminal on the battery cell 20, and the energy storage power source 10 can controllably supply power to the battery cell 20 based on information about the battery cell 20 received by the first communication terminal. To avoid danger caused by the charging unit 15 supplying power to an incompatible battery, the plurality of first connection terminals 151 of the charging unit 15 are provided with terminals for achieving communication connection, and the first communication terminal can communicatively connect with a compatible battery cell 20, and the energy storage power source 10 receives a communication code transmitted from the battery cell 20 and only starts charging the battery cell 20 when it confirms that the communication code matches the requirements, thereby avoiding safety dangers caused by the energy storage power source charging an incompatible battery.

[0101] In the second embodiment of the charging unit 15, the charging unit 15 charges the battery cell 20 using wireless charging, that is, wireless charging can be performed when the battery cell 20 approaches the charging unit 15. The operating principle of the charging unit 15 for wireless charging is to transmit electrical energy to the battery cell 20 by a method such as, but not limited to, electromagnetic induction, magnetic resonance, microwave electrical transmission, etc.

[0102] [Electricity equipment (31, 32)]

[0103] The electricity-using equipment includes a first electricity-using equipment 31 that is adapted to the battery cell 20 and a second electricity-using equipment 32 that is adapted to the energy storage power source 10 .

[0104] The second electrical usage equipment 32 may be a DC electrical usage equipment or an AC electrical usage equipment, i.e., the second electrical usage equipment 32 is adapted to be directly powered by the energy storage power source 10 by electrically connecting to the DC output interface 121 or the AC output interface 122.

[0105] The first electricity-using equipment 31 is only DC electricity-using equipment including power-driven power tools (e.g., lawn mowers, electric drill drivers, vacuum cleaners, etc.) or non-power-driven electrical equipment (e.g., work radios, work lights, etc.). Note that the power drive can be implemented as a motor drive.

[0106] In particular, the first electricity consumption equipment 31 is cordlessly connected to the battery pack 20A and configured to receive power directly from the battery pack 20A.

[0107] The battery pack 20A generally refers to a power tool battery or battery pack having a nominal voltage, such as 4V, 12V, or 18V. The battery pack 20A includes a housing, a tool interface (i.e., a charging / discharging connection), and a latch that selectively locks the tool interface to the battery interface of the first electricity-using device 31. Specifically, the battery pack 20A supplies power to the first electricity-using device 31 from the cell core via the power terminal, and communicates and identifies with the first electricity-using device 31 via the communication terminal. Only when the handshake identification communication between the battery pack 20A and the first electricity-using device 31 is successful, does the first electricity-using device 31 receive power and operate.

[0108] [First aspect of the present invention]

[0109] According to a first aspect of the present invention, there is provided an energy storage power supply 10 comprising a housing 14, the housing 14 comprising at least two housing sections 142, the different housing sections 142 adapted to detachably house the same battery cells 20, and a charging section 15 for supplying power to the battery cells 20 provided within the housing sections 142, i.e., the energy storage power supply 10 charges the battery cells 20 via the charging section 15, and the battery cells 20 are adapted to supply power to a first electricity-using device separately from the energy storage power supply 10 when the power of one battery cell 20 is used up, using another different battery cell 20 to continue supplying power to the first electricity-using device.

[0110] According to a first aspect of the present invention, there is further provided an energy storage facility comprising an energy storage power source 10 and at least two identical battery cells 20, wherein the energy storage power source 10 detachably houses the battery cells 20 and is adapted to cordlessly power the battery cells 20, and each battery cell 20 is adapted to alternately power a first electricity-using device 31. Through cooperation between the at least two identical battery cells 20 and the energy storage power source 10, the first electricity-using device 31 can be continuously powered in a usage scenario away from the energy storage power source 10.

[0111] The energy storage power supply 10 of the present invention can provide charging and storage for at least two battery cells 20 of the first electricity-using device 31, i.e., can provide charging and storage for at least one spare battery cell 20, so that when one battery pack 20A of the first electricity-using equipment 31 runs out of power, it can be quickly replaced with another spare battery pack 20A to ensure continuous use of the first electricity-using equipment 31, thereby effectively solving the problem of the range of use of the first electricity-using equipment 31 being limited due to an inability to continue power supply.

[0112] During a wide variety of outdoor activities, such as outdoor barbecues, outdoor movie nights, and sports, electrical equipment such as induction furnaces, audio and video equipment, lighting, and communications equipment may be used. Since supplying electricity outdoors is inconvenient, energy storage equipment is needed to supply power to these electrical devices. Conventional energy storage devices typically require electrical wires to connect to electrical devices, which can be inconvenient outdoors. For example, when electrical connections are made using electrical wires, the electrical devices cannot be used remotely from the energy storage device. Furthermore, when electrical connections are made using electrical wires, the wires can be scattered on the ground, creating a risk of users tripping and falling, and potentially resulting in electric shock.

[0113] The application of the energy storage power supply 10 of the present invention will be further described using an outdoor usage scenario as an example. As shown in Figures 3 and 4, user A and user B are using a cooking appliance 32, and user C is using an entertainment device 31. The cooking appliance 32 is directly powered by the energy storage power supply 10, i.e., the cooking appliance 32 is electrically connected to the energy storage power supply 10 via an electric wire. Because the entertainment device 31 is powered by one battery pack 20A, user C's activity area is not limited by the energy storage power supply 10 and can be located away from the cooking appliance 32. After the entertainment device 31 has consumed power for a certain period of time, the user can remove the battery pack 20A from the entertainment device 31 and store it in the energy storage power supply 10 for charging, and can also take out the spare battery pack 20A stored in the energy storage power supply 10 and install it in the entertainment device 31 to ensure continuous use of the entertainment device 31.

[0114] The energy storage power supply 10 of the present invention, on the one hand, supports charging of the battery cells 20, and on the other hand, the energy storage power supply 10 itself has a DC output interface 121 and / or an AC output interface 122, so that it can directly satisfy the power demand of the second electricity-using device 32. Therefore, when a battery pack 20A is disposed on the energy storage power supply 10, the energy storage power supply 10 is adapted to supply charging for the battery pack 20A. When the battery pack 20A is removed from the energy storage power supply 10, the battery pack 20A is cordlessly coupled to and supplies power to the first electricity-using device 31, and the first electricity-using device 31 and the second electricity-using device 32 are adapted to operate independently of each other by the corresponding battery pack 20A and energy storage power supply 10. Here, the capacity of the energy storage 10 is greater than that of the battery pack 20A.

[0115] In particular, when battery pack 20A is placed on energy storage power source 10, energy storage power source 10 is adapted to charge battery pack 20A at an average charging current of 4 A or more. Alternatively, battery pack 20A will be charged from energy storage power source 10 at a rate of at least 1 C.

[0116] According to a first aspect of the present invention, the housing 14 includes at least two storage compartments 142, each adapted to detachably store the same battery cell 20. In this case, two identical battery cells 20, for example, two identical battery packs 20A, can be removed and simultaneously cordlessly connected to the first electrical usage device 31, which is a double-pack electrical usage device configured with two mounting sections for cordlessly connecting the battery packs 20A. In this case, the two identical battery packs 20A are connected in series or parallel via electrical circuits, and examples of this double-pack electrical usage device include a double-pack car wash (see CN114512761A) and a double-pack grass cutter (see CN2162188791U).

[0117] [Second Aspect of the Present Invention]

[0118] According to a second aspect of the present invention, there is provided an energy storage power supply 10 comprising a housing 14, the housing 14 comprising an accommodating portion 142 adapted to detachably accommodate an integrated pack 20B, the accommodating portion 142 being provided with a charging portion 15 for powering the integrated pack 20B, the integrated bag 20B comprising a mounting box 21 and a plurality of battery packs 20A removably mounted in the mounting box 21, the battery packs 20A being adapted to supply power to a first electricity-using device 31 separate from the mounting box 21.

[0119] According to a second aspect of the present invention, there is further provided an energy storage facility comprising an energy storage power source 10 and an integrated pack 20B, wherein the energy storage facility 10 detachably houses the integrated pack 20B and is adapted to power the integrated pack 20B by cordless power supply or wireless charging, and the integrated pack 20B comprises a mounting box 21 and a plurality of battery packs 20A removably arranged on the mounting box 21, wherein when the integrated pack 20B is powered, the individual battery packs 20A arranged on the mounting box 21 are powered, and the battery packs 20A are adapted to power a first electricity-using device 31 in isolation from the mounting box 21.

[0120] The energy storage power supply 10 of the present invention can provide charging and storage for a plurality of battery packs 20A of the first electricity-using device 31, i.e., can provide charging and storage for at least one spare battery pack 20A, so that when one battery pack 20A of the first electricity-using device 31 runs out of power, it can be quickly replaced with the other spare battery pack 20A to ensure continuous use of the first electricity-using device 31, effectively solving the problem of limited range of use of the first electricity-using device 31 due to unreliable power supply. Furthermore, the integrated pack 20B allows for easy centralized charging of the plurality of battery packs 20A, and the plurality of battery packs 20A can be stored together in the mounting box 21, solving the problem of storage after the plurality of battery packs 20A are removed from the storage power supply 10.

[0121] According to a second aspect of the present invention, the energy storage power supply 10 of the present invention is adapted to charge the battery cells 20 on the one hand, and on the other hand, the energy storage power supply 10 itself has a DC output interface 121 and / or an AC output interface 122 and can directly satisfy the power demand of the second electricity-using device 32. Therefore, when a battery pack 20A is disposed on the energy storage power supply 10, the energy storage power supply 10 is adapted to supply charging for the multiple battery packs 20A in the integrated pack 20B. When the battery pack 20A is removed from the integrated pack 20B, the battery pack 20A is cordlessly coupled to and powers the first electricity-using device 31, and the first electricity-using device 31 and the second electricity-using device 32 are adapted to operate independently of each other by the corresponding battery pack 20A and energy storage power supply 10. Here, the capacity of the energy storage 10 is greater than the sum of the capacities of the individual battery packs 20A in the integrated pack 20B.

[0122] In particular, when the storage power source 10 supplies power to the integrated pack 20B via cordless power supply or wireless charging, it prioritizes identifying the current power amount of each battery pack 20A and charges the battery pack 20A with the highest current power amount first to fully charge it in the shortest time possible, followed by charging the battery packs 20A with the lowest power amounts sequentially, allowing the user to obtain a fully charged battery pack 20A in a shorter time. Thus, when the user uses up the power of this fully charged battery pack 20A, the power amount of the other battery pack is also fully charged, allowing for efficient power exchange by the user.

[0123] Of course, if the charging power is allowed, the average charging current of each battery pack 20A can preferably be 4 A or more. Alternatively, each battery pack 20A will be charged from the energy storage power source 10 at a rate of at least 1 C.

[0124] According to a second aspect of the present invention, each battery pack 20A in the integrated pack 20B of the present invention is the same, i.e., has the same specifications, size, and voltage. In this case, the integrated pack 20B can also be provided with a discharge interface such as a USB interface or a Type-C interface. Multiple battery packs 20A are arranged in parallel with each other in the mounting box 21 of the integrated pack 20B, and the entire integrated pack 20B can be used as a mobile power source. Removing any one battery pack 20A from the mounting box 21 of the integrated pack 20B will not affect the discharge output of the entire integrated pack 20B.

[0125] [Third aspect of the present invention]

[0126] According to a third aspect of the present invention, there is provided an energy storage power supply (10) comprising a housing (14), the housing (14) comprising at least two accommodation sections (142), the at least two accommodation sections (142) including at least one first accommodation section (142A) and at least one second accommodation section (142B), the first accommodation section (142A) adapted to separably accommodate a first battery cell, and the second accommodation section (142B) adapted to separably accommodate a second battery cell, the first battery cell and the second battery cell being different. A charging section (15) is provided within each accommodation section (142) for supplying power to the first battery cell or the second battery cell, and the first battery cell and the second battery cell are adapted to supply power to the same or different first electrical device (31) separate from the energy storage power supply (10).

[0127] The structures of the first and second battery packs can be referred to in connection with the battery pack 20A, and will not be further described here.

[0128] Note that the first battery cell and the second battery cell being different means that the first battery cell and the second battery cell are different battery cells 20, and the two may have different shapes, different charging / discharging methods, different assembly formats, etc.

[0129] Preferably, the first battery cell is a first battery pack, which is adapted to power a first electricity-using device 31 separate from the energy storage power source 10. The second battery cell is an integrated pack 20B, which includes a mounting box 21 and a plurality of second battery packs removably arranged on the mounting box 21, which are adapted to power the first electricity-using device 31 separate from the mounting box 21.

[0130] The structures of the first and second battery packs can be referred to in connection with the battery pack 20A, and will not be further described here.

[0131] The first battery pack and the second battery pack are different, i.e., the first battery pack and the second battery pack are different battery packs 20A, and the two may have different shapes, different charging / discharging methods, or different capacities. The different battery packs 20A are adapted to supply power to different first electricity-consuming devices 31.

[0132] According to a third aspect of the present invention, there is further provided an energy storage device comprising an energy storage power source 10, at least one first battery cell, and at least one second battery cell, wherein the energy storage power source 10 detachably houses the first battery cell and the second battery cell and is adapted to cordlessly power the first battery cell and the second battery cell, and the first battery cell and the second battery cell are adapted to power the same or different first electricity-using equipment separately from the energy storage power source 10.

[0133] The energy storage power supply 10 of the present invention can charge different battery cells compatible with different first electricity-using equipment 31, and after charging is complete, each battery cell can be removed from the energy storage power supply 10 and attached to the corresponding first electricity-using equipment 31, allowing the different first electricity-using equipment 31 to be used separately in locations away from the energy storage power supply 10. In addition, different battery cells of different first electricity-using equipment 31 can be stored in and powered by the energy storage power supply 10, thereby expanding the application range of the energy storage power supply 10, i.e., the energy storage power supply 10 can charge battery cells of more types of first electricity-using equipment 31.

[0134] According to a third aspect of the present invention, the first battery pack and the second battery pack are different, i.e., the battery pack 20A is different from the first battery pack and the second battery pack, and there are multiple first battery packs and multiple second battery packs, all of which can be charged from the energy storage power source 10 by cordless power supply or wireless charging, and the different battery packs 20A are adapted to supply power to different first electricity-using devices 31. Therefore, according to the third aspect of the present invention, on the one hand, the power demand of the second electricity-using device 32 can be met through the DC output interface 121 and / or the AC output interface 122 possessed by the energy storage power source itself, and on the other hand, different first electricity-using devices 31 can be supplied with power by different battery packs 20A, thereby expanding the application scope of the energy storage power source 10, enriching the power usage scenarios, and also meeting different power usage needs of users.

[0135] Specifically, the energy storage power source 10 can satisfy the power demand of a DC type second electricity-using device 32 via the DC output interface 121 and / or can satisfy the power demand of an AC type second electricity-using device 32 via the AC output interface 122.

[0136] The first battery pack and the second battery pack are different battery packs 20A, such that the first output voltage (e.g., 20V) of the first battery pack is greater than the second output voltage (e.g., 4V) of the second battery pack, thereby allowing the first battery pack to meet the power demand of the first electricity-using equipment 31 that uses the first output voltage (e.g., 20V) as its driving voltage type, and the second battery pack to meet the power demand of the first electricity-using equipment 31 that uses the second output voltage (e.g., 4V) as its driving voltage type.

[0137] [Fourth aspect of the present invention]

[0138] According to a fourth aspect of the present invention, there is provided an energy storage device comprising a housing body 141 and an accommodating portion 142. The housing body 141 has a front surface, and a plurality of output interfaces are provided on the front surface of the housing body, and the second electricity-consuming device 32 is adapted to be electrically connected to the output interfaces so as to be directly powered by the energy storage power source 10. The accommodating portion 142 is used to detachably accommodate the battery cells 20, and the battery cells 20 are adapted to supply power to the first electricity-consuming device 31 separately from the energy storage power source 10, and the accommodating portion 142 is provided in the housing body 141, and an opening of the accommodating portion 141 is exposed to the front surface of the housing body 141, so that the battery cells 20 in the accommodating portion 142 can be removed from the front surface of the housing body 141.

[0139] A first side surface 1413 of the housing body 141 is the front surface. A third side surface 1415 of the housing body 141 is not provided with an interface for outputting a current.

[0140] Since the front of the energy storage power supply 10 is the surface that is frequently used, when the user places the energy storage power supply 10, the user normally places the front of the energy storage power supply 10 facing the user, and by providing the opening 1420 of the storage section 142 on the front, it becomes easy for the user to observe the charging state of the battery cell 20, remove the battery cell 20 from the storage section 142, and insert the battery cell 20 into the storage section 142.

[0141] [Fifth aspect of the present invention]

[0142] According to a fifth aspect of the present invention, there is provided an energy storage power supply 10 including a housing body 141, an accommodating portion 142, at least one DC output interface 121, and at least one AC output interface 122. The housing body 141 has adjacent first and fourth side surfaces 1413 and 1416. The accommodating portion 142 is used to separably accommodate battery cells 20, and the battery cells 20 are adapted to supply power to a first electricity-using device 31 separately from the energy storage power supply 10. The body of the accommodating portion 142 is provided in the housing body 141, and an opening 1420 of the accommodating portion 142 is formed in a surface of the housing body 141.

Each DC output interface 121 is provided on the first side surface 1413, and each AC output interface 122 is provided on the fourth side surface 1416.

[0143] The third side surface 1415 of the housing body 141 is not provided with an interface for outputting a current.

[0144] The DC output interface 121 of the energy storage power supply 10 is mainly provided on the first side surface 1413, and the AC output interface 122 is mainly provided on the fourth side surface 1416. By providing the accommodating section 142 at the joint between the first side surface 1413 and the fourth side surface 1416, the internal space of the housing body 141 can be utilized more effectively and the components inside the housing body 141 can be installed more compactly, which is advantageous for miniaturizing the energy storage power supply 10.

[0145] [Example 1]

[0146] 1 and 2, the energy storage facility of Example 1 includes an energy storage power supply 10 and two battery packs 20A.
