Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0031] Outdoor battery cabinets are mainly used for energy storage and power supply, and can adapt to outdoor environments, such as outdoor emergency backup power supply, outdoor activity power supply, etc. However, in the prior art, a battery cabinet can only be customized for a specific scenario, and the customized battery cabinet cannot be combined and expanded at will, which limits the application conditions of a certain battery cabinet and cannot be applied to multiple scenarios, resulting in poor compatibility.

[0032] Combined with reference Figure 1 The utility model provides an outdoor battery cabinet for outputting battery energy. The outdoor battery cabinet includes a plurality of battery cabinets 100 and a functional cabinet 200.

[0033] In this embodiment, each battery cabinet 100 has a battery pack 110, and each battery pack 110 contains a battery 111. Each battery cabinet 100 is provided with a power interface 130, and the power interface 130 is electrically connected to the battery pack 110. In this embodiment, a plurality of conductive connection components 210 are provided in the functional cabinet 200. The plurality of conductive connection components 210 can be combined and selected to connect the battery packs 110 of a plurality of battery cabinets 100 in series or in parallel.

[0034] It should be noted that each battery cabinet 100 in this embodiment can be regarded as a single battery, and multiple conductive connection components 210 can serve as connection nodes for the positive and negative electrodes of the above-mentioned battery cells. By selectively connecting the power interface 130 of the battery cabinet 100 to the conductive connection component 210, multiple battery cabinets 100 can be connected in parallel or in series, and the energy or power of multiple battery cabinets 100 after series or parallel connection can be output. It can be understood that different numbers of battery cabinets 100 connected in series or in parallel can have different output power and energy, and the corresponding voltage platforms will also be different. Therefore, the series-parallel combination of this embodiment can be used to cope with various power requirements and voltage platform requirements during application, thereby improving the compatibility and flexibility of the outdoor battery cabinet.

[0035] Each battery cabinet 100 in this outdoor battery cabinet has 100KWH of energy. The functional cabinet 200 in this embodiment can realize parallel or series connection of multiple battery cabinets 100. When two battery cabinets 100 are connected in series or in parallel, the energy of the outdoor battery cabinet can be expanded to 200KWH, 300KWH or higher. Therefore, this embodiment has a strong energy expansion capability.

[0036] It can be understood that, ideally, energy is proportional to voltage and current, that is, E∝VI. The difference between two batteries connected in series and in parallel is that when two batteries are connected in series, the voltages of the two batteries are superimposed and the current remains unchanged; when two batteries are connected in parallel, the currents of the two batteries are superimposed and the voltage remains unchanged. Therefore, the energy expanded by connecting in series and in parallel is the same, that is, whether in parallel or in series, the outdoor battery cabinet can achieve the function of energy expansion.

[0037] In addition, the outdoor battery cabinet in this embodiment can be expanded in series. Since the series-connected batteries can add up the voltages of all batteries, it is compatible with multiple voltage platforms.

[0038] Similarly, multiple clusters can be connected in parallel, increasing the total current of the battery system to adapt to applications that require higher power output and being compatible with a variety of power levels.

[0039] It can be seen that the utility model realizes the series connection and parallel connection between the battery cabinets 100 through a functional cabinet 200, which plays a role in improving adaptability and the flexibility of the outdoor battery cabinet, so that it can adapt to different voltage requirements and different power requirements. This means that the battery system can be used in different application scenarios without being restricted by a specific voltage platform and a specific power level. Therefore, compared with some examples, this embodiment has higher compatibility and avoids the outdoor battery cabinet being used only for a specific scenario.

[0040] In this embodiment, there are multiple battery packs 110 in the battery cabinet 100. The multiple battery packs 110 are connected in series. After the batteries 111 are placed in the battery packs 110, multiple series-connected battery groups are formed.

[0041] It is understandable that multiple battery packs 110 connected in series can achieve energy selectivity of a single battery cabinet 100, and the total energy and voltage of the battery cabinet 100 can be controlled by the number of batteries placed. If a larger battery pack 110 is set to replace multiple relatively small battery packs 110, the structure will be bulky, unable to be adjusted accordingly according to needs, and poor compatibility.

[0042] In this embodiment, the power interface 130 includes a positive terminal 131 and a negative terminal 132, the positive terminal 131 is connected to the positive pole of the series battery group, and the negative terminal 132 is connected to the negative pole of the series battery group, that is, the positive and negative terminals 132 of the power interface 130 of each battery cabinet 100 are integrated with the positive and negative poles of the corresponding series battery group, which helps to achieve faster series or parallel connection or connection switching, etc.

[0043] In this embodiment, a plurality of battery packs 110 are arranged in parallel along the vertical direction of the battery cabinet 100, so that the batteries 111 of the outdoor battery cabinet can be easily disassembled and can be more conveniently adapted to different situations.

[0044] In this embodiment, the conductive connection assembly 210 includes a plurality of conductive connection plates 220 and a connector 230. The plurality of conductive connection plates 220 are arranged in the functional cabinet 200. One end of the connector 230 is connected to the power interface 130 of the battery cabinet 100, and the other end is connected to the corresponding conductive connection plate 220. The connection mode is selected according to the needs, and can be selected in series or in parallel. It should be explained that the above is described by a simple circuit diagram, that is, the battery cabinet 100 is a power source, the connector 230 is a wire, and the plurality of conductive connection plates 220 are nodes. By combining and connecting the positive terminal 131, the negative terminal 132 and the plurality of conductive connection plates 220 of each battery cabinet 100, it is possible to connect the plurality of battery cabinets 100 in series or in parallel or in series and in parallel. Multiple wires are used to connect the battery cabinet 100 and the functional cabinet 200. One end of the wire is connected to the positive terminal 131 or the negative terminal 132 of the battery cabinet 100, and the other end is connected to the corresponding conductive connection plate 220 to achieve current diversion between the plurality of battery cabinets 100.

[0045] In this embodiment, the conductive connecting plate 220 is a first copper plate 221, a second copper plate 222, a third copper plate 223 and a fourth copper plate 224 arranged at intervals, and the connecting member 230 includes multiple wires. The four copper plates can realize connecting all the battery cabinets 100 in parallel, and can also realize connecting multiple battery cabinets 100 in parallel and then connecting a battery cabinet 100 in series, and can also realize connecting two battery cabinets 100 in series. Series connection or parallel connection can be achieved through different connection methods, and the connection method depends on the requirements of the scene. This design greatly improves the compatibility of this outdoor battery cabinet.

[0046] Combined with reference Figure 2 In this embodiment, the method for realizing parallel connection is: multiple wires connect the positive terminal 131 of each battery cabinet 100 to the first copper plate 221, and connect the negative terminal 132 of each battery cabinet 100 to the second copper plate 222. Thus, the energy of the battery cabinets 100 connected in parallel can be outputted from the first copper plate 221 and the second copper plate 222, realizing energy expansion and improving the compatibility of the voltage platform.

[0047] Combined with reference Figure 3In this embodiment, the method for realizing series connection is: multiple wires connect the positive terminal 131 of the power interface 130 of at least one battery cabinet 100 to the first copper plate 221, the negative terminal 132 to the second copper plate 222, connect the negative terminal 132 of the power interface 130 of at least one battery cabinet 100 to the third copper plate 223, the positive terminal 131 to the fourth copper plate 224, and the second copper plate 222 is connected to the fourth copper plate 224. Thus, the energy of the battery cabinets 100 connected in series can be output at the first copper plate 221 and the third copper plate 223, realizing energy expansion and improving the power compatibility of the outdoor battery cabinet.

[0048] Combined with reference Figure 4 In this embodiment, the method for realizing the series-parallel combination is: multiple wires connect the positive terminals 131 of at least two battery cabinets 100 to the first copper plate 221, the negative terminals 132 to the second copper plate 222, and the positive terminal 131 of at least one battery cabinet 100 is connected to the first copper plate 221, the negative terminal 132 is connected to the third copper plate 223, the negative terminal 132 of at least one battery cabinet 100 is connected to the second copper plate 222, the positive terminal 131 is connected to the fourth copper plate 224, and the third copper plate 223 is connected to the fourth copper plate 224. Thus, the energy of multiple battery cabinets 100 connected in parallel can be output by the first copper plate 221 and the second copper plate 222, and then connected in series, thereby realizing energy expansion and improving compatibility.

[0049] It should be explained that the above are only three embodiments for realizing series-parallel connection, which does not mean that the outdoor battery cabinet can only realize the above three connection methods, nor does it mean that series-parallel connection can only be realized by the means of the above embodiments. By reasonably designing the circuit and connecting the wires, an outdoor battery cabinet that is compatible with the application scenario can be designed.

[0050] In addition, the plurality of conductive connecting plates 220 may be more than four copper plates. More than four copper plates provide greater design flexibility for the outdoor battery cabinet, so that the battery system can better meet the requirements of different application scenarios, and more complex battery pack connection methods can be achieved through more than four copper plates, thereby improving the adjustability and adaptability of the system.

[0051] In this embodiment, the wire is provided with a protective outer layer. The wire is often exposed to various environments, including moisture, chemicals, ultraviolet rays, etc. The protective outer layer can resist the influence of these environmental factors on the performance of the wire, ensuring that the wire can operate normally under different conditions, thereby indirectly improving the performance of the outdoor battery cabinet.

[0052] In this embodiment, the first copper plate 221, the second copper plate 222, the third copper plate 223 and the fourth copper plate 224 are respectively installed in the functional cabinet 200 through insulating seats. The use of the insulating seats can effectively isolate the copper plates to prevent electrical short circuits between them, which is very important for ensuring the stability and safety of the battery system, especially in the case of high voltage or high power.

[0053] In this embodiment, if Figure 1 As shown, the function cabinet 200 is combined with one of the battery cabinets 100 into a main battery cabinet, that is, one battery cabinet 100 is selected as the main battery cabinet, connected to the function cabinet 200, and unified output is achieved from the main battery cabinet, simplifying the output management of the battery system. And the confluence part is integrated in the main cabinet. Such a design reduces the required electrical connection components and cables, simplifies the physical structure of the system, and thus improves the overall economy.

[0054] In this embodiment, multiple battery cabinets 100 are formed by a first shell, and the multiple battery cabinets 100 are spaced apart along the vertical direction of the first shell, and the functional cabinets 200 are formed by a second shell, and the first shell and the second shell are arranged side by side and connected to each other; or, multiple battery cabinets 100 and multiple functional cabinets 200 are formed by a third shell, and the multiple battery cabinets 100 are spaced apart along the vertical direction of the third shell.

[0055] It can be explained that the shell provides outer protection for the battery cabinet 100 and the functional cabinet 200 , and also determines the shapes of the battery cabinet 100 and the functional cabinet 200 .

[0056] In this embodiment, the shells of the battery cabinet 100 and the functional cabinet 200 have anti-corrosion and protection functions. The shells of the battery cabinet 100 and the functional cabinet 200 in this outdoor battery cabinet have an IP54 protection level and a C3 anti-corrosion level, and have strong environmental adaptability. They can not only operate stably under a variety of environmental conditions, but also extend the life of the equipment and reduce maintenance costs. The IP54 protection level means that the equipment has a 5-level dustproof level and a 4-level waterproof level, and has a good dustproof and waterproof effect. It can effectively prevent fine particles from entering the interior of the equipment, and can also ensure that the equipment can maintain a good operating state in rain or humid environments, and is not easily damaged by moisture and water. The C3 anti-corrosion level indicates that the shells of the battery cabinet 100 and the functional cabinet 200 have a certain corrosion resistance, can work in a mildly corrosive environment without being damaged, and effectively resist corrosive substances that may exist in the outdoor environment, such as salt spray or chemical vapor, and extend the service life of the equipment.

[0057] In this embodiment, each battery cabinet 100 also includes a high-voltage box 120, which serves as a high-voltage power supply control and protection unit, and provides functions such as charge and discharge control, power-on control of high-voltage components, circuit overload and short-circuit protection, high-voltage sampling, low-voltage control, and battery temperature regulation for the outdoor battery cabinet, and protects and monitors the operation of the high-voltage system. In this embodiment, the positive terminal 131 and the negative terminal 132 of the battery cabinet 100 are arranged in the above-mentioned high-voltage box 120, which can better protect the batteries in the battery cabinet 100 and can also more conveniently realize line switching.

[0058] It is understandable that the high voltage box 120 provides multiple functions for the battery cabinet 100 to ensure stable, safe and efficient operation of the high voltage system. This integrated design helps to simplify the system structure and improve the reliability and performance of the system.
