Description

Technical Field

[0001] This utility model belongs to the field of outdoor communication technology, and specifically relates to a battery box for outdoor communication base stations. Background Technology

[0002] Outdoor communication base stations are a crucial infrastructure component of modern wireless communication systems. They primarily function to transmit, receive, process, and forward wireless communication signals, and are widely used in mobile communications, the Internet of Things (IoT), and emergency communications. Their core mission is to establish wireless connections with terminal devices within their coverage area, enabling the efficient transmission of various information types, including voice, data, and video.

[0003] With the rapid development of 5G communication technology, outdoor communication base stations are playing an increasingly important role in improving communication network coverage, enhancing user experience, and meeting the demand for massive connections. Especially in remote areas, emergency scenarios, industrial parks, and along highways where traditional communication infrastructure cannot be deployed, outdoor communication base stations, with their advantages of independent power supply, rapid deployment, and compact structure, have become a key means of achieving communication service coverage.

[0004] Existing outdoor communication base stations can be broadly categorized based on their functional characteristics and deployment methods as follows: Macro base stations: Larger in size, higher in power, and with wider coverage, suitable for urban main roads, rural areas, and mountainous regions. Micro base stations and pico base stations: Smaller in size, used in urban hotspot areas, etc. Integrated base stations: Integrate communication modules, power supply systems, heat dissipation systems, and antennas, suitable for rapid deployment scenarios. Portable / emergency communication base stations: Possess mobility and are often used for temporary communication support during emergencies.

[0005] Despite the wide variety of existing outdoor communication base stations, numerous technical bottlenecks remain in practical applications. For instance, the capacity requirements for battery power systems vary significantly across different application scenarios, while most current base station battery boxes employ a fixed-capacity design, lacking flexible modular expansion capabilities. When communication service loads increase or sites expand, the existing battery system often cannot meet the demands for higher power or longer battery life, necessitating the replacement of the entire power supply equipment. This increases maintenance costs and reduces system scalability and deployment efficiency.

[0006] Furthermore, some existing base stations have certain shortcomings in terms of environmental adaptability, protection level, intelligent monitoring, and remote operation and maintenance, making it difficult to meet the comprehensive requirements of high reliability and intelligence for 5G network construction. Therefore, there is an urgent need for a new type of outdoor communication base station battery box system that features scalable capacity, flexible installation methods, high security, and adaptability to complex environments to solve the above problems and promote the efficient and sustainable development of communication networks. Summary of the Invention

[0007] To address the aforementioned technical problems, this utility model provides a battery box for outdoor communication base stations. By modularizing the battery design, it supports multiple battery packs connected in parallel to expand capacity, achieving flexible capacity expansion to meet different power requirements.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A battery box for outdoor communication base stations includes a battery box body, which includes a battery box top cover and a battery box bottom cover, which are hinged together. Multiple battery packs are arranged inside the battery box body and are connected in parallel.

[0010] By adopting the above technical solution, this utility model employs a modular design for the battery pack, allowing multiple battery packs to be connected in parallel for capacity expansion. Compared to traditional communication base station battery boxes with fixed capacity designs, this utility model can flexibly configure the number of battery packs according to the power and backup time required by the actual usage scenario, improving the system's adaptability and economy, and avoiding the waste of replacing the entire system due to insufficient battery capacity. Because the battery packs adopt a standardized modular design, during system operation, when some batteries experience performance degradation or malfunction, only the corresponding module needs to be replaced, without replacing the entire system, reducing later maintenance costs and extending the overall service life. The parallel connection between multiple battery packs helps improve the stable discharge capability of the entire system under high load conditions, avoiding overload of a single battery pack, effectively reducing the risk of power outages, and improving the reliability and stability of the communication base station operation. Since the battery box structure uses a hinged upper and lower cover, it facilitates on-site installation and maintenance. Combined with the flexibility of parallel modules, it can adapt to different types of communication equipment such as macro base stations and micro base stations, as well as various installation methods such as wall-mounted, flag-mounted, and floor-standing installations, possessing good versatility and engineering application promotion value.

[0011] Furthermore, the battery pack includes multiple battery modules connected in series.

[0012] By adopting the above technical solution, the battery modules are connected in series, which improves the overall output voltage of the battery pack, thereby meeting the power supply requirements of various devices in outdoor communication base stations for different voltage levels and improving system compatibility and stability. By connecting multiple small-capacity unit modules in series to form a large-capacity high-voltage battery pack, the energy density per unit volume can be increased while maintaining the overall size of the battery box, providing longer battery life for base station equipment. This also helps to reduce the size of the battery box and adapt to more confined outdoor installation spaces.

[0013] As a further feature, the battery module is equipped with a safety valve.

[0014] By adopting the above technical solution, the safety valve, as the core protective component of the battery module, can automatically release pressure when the internal air pressure rises abnormally, preventing dangerous situations such as battery casing rupture and thermal runaway. Each battery module is equipped with an independent safety valve. When a danger such as overcharging, short circuit, or heat accumulation occurs inside a module, the pressure of that module can be locally released or its operation can be interrupted, preventing thermal runaway from being conducted to adjacent modules and preventing the chain reaction of failures, thereby ensuring the stable operation of the entire battery pack and even the communication base station system.

[0015] In a further configuration, the lower cover of the battery box is provided with an operation interface panel, which is located outside the lower cover of the battery box.

[0016] By adopting the above technical solution, the operation interface panel is located outside the battery box's lower cover. Maintenance personnel can perform daily connection, monitoring, and operation tasks without opening the battery box, significantly improving the equipment's operability. This makes it suitable for rapid deployment and maintenance in outdoor environments, avoiding sealing damage and structural aging issues caused by frequent opening. The external interface layout facilitates centralized management of power output ports, communication interfaces, maintenance interfaces, and other functional ports, standardizing wiring procedures and avoiding problems such as misconnections, short circuits, and electric shocks caused by opening the box, thus improving the overall system's operational safety and stability. The centralized layout of the interface panel outside the lower cover effectively isolates heat-generating components from the battery cell structure, reducing heat accumulation inside the box and optimizing the overall heat dissipation structure, thereby extending the lifespan of the battery and electronic components. The external operation panel provides sufficient wiring and structural space, suitable for integrating multiple functional interfaces such as power output ports, RS485 / RS232 communication interfaces, maintenance interfaces, and status indicator lights. It also facilitates the subsequent integration of intelligent devices such as remote control modules and data acquisition units, meeting the development needs of intelligent power supplies for 5G base stations. The external interface design of the lower cover is not constrained by the internal structure of the enclosure, and can adapt to different installation methods such as wall mounting, flag mounting, and floor mounting. Even if the enclosure is installed at a high place or in a corner, the plug-in connection and status can be completed through the control panel below, improving the flexibility and reliability of on-site deployment.

[0017] Furthermore, the operation interface panel is equipped with a power output port, a communication interface, a maintenance interface, status indicator lights, and a switch.

[0018] By adopting the above technical solution, all key functional interfaces are centrally located on a single panel, reducing the problems of cluttered external wiring and scattered equipment. This facilitates one-stop access and operation for on-site engineers, while also improving structural compactness and suitability for standardized installation and deployment. Through a standardized power output port, the battery box is compatible with communication base station equipment of different power levels without the need for additional adaptations, improving system versatility and deployment efficiency. It is particularly suitable for base station scenarios where multiple devices coexist, such as 5G and edge computing.

[0019] Further, the battery box body is equipped with handles, wall-mounted fixing brackets, and flag fixing brackets on its exterior.

[0020] By adopting the above technical solutions, the handle design facilitates manual lifting, moving, or adjustment of the battery box position by construction personnel during transportation, handling, and on-site setup. This is suitable for base station installation scenarios where manual labor is the primary method, reducing labor intensity and improving deployment efficiency and safety. The configuration of wall-mounted and flag-mounted brackets can adapt to different types of outdoor installation environments, such as mounting on base station cabinet walls, installing on poles, angle steel towers, communication towers, or flag-mounted brackets, effectively addressing the complex and diverse site requirements in urban, suburban, and mountainous areas.

[0021] Furthermore, the battery box is formed by die-casting aluminum alloy.

[0022] By adopting the above technical solutions, the structure boasts high strength. The die-cast aluminum alloy parts possess excellent strength and rigidity, effectively resisting external impacts, vibrations, and mechanical stresses generated during handling. This ensures the overall stability and structural integrity of the enclosure in harsh outdoor environments, reducing operational failures caused by damage to the casing. Aluminum alloy itself exhibits excellent corrosion resistance, and the die-cast surface can undergo further protective treatments such as anodizing and electrophoretic coating to enhance its resistance to salt spray, rain, and ultraviolet radiation, making it highly suitable for outdoor communication base station scenarios under various complex climatic conditions, including high humidity, high temperature, and extreme cold. Aluminum alloy has excellent thermal conductivity, allowing for natural heat dissipation through the enclosure without relying on additional cooling components such as fans. This rapidly transfers heat generated during battery operation to the external environment, reducing cell temperature rise and improving battery life and safety. The die-casting process enables high-precision, high-complexity integrated molding, ensuring dimensional consistency and interface alignment accuracy across all parts. This facilitates efficient assembly and standardized production of components such as battery modules, panels, and brackets, reducing manual adjustments and rework costs. Compared to traditional steel or iron enclosures, aluminum alloy materials are lighter while maintaining strength, which helps to reduce the overall load on the equipment, improve transportation efficiency, and reduce the installation strength and structural burden in high-altitude or wall-mounted scenarios.

[0023] Furthermore, a battery management system is installed inside the main body of the battery box.

[0024] By adopting the above technical solutions, the battery management system (BMS) can monitor key parameters such as voltage, current, and temperature of each cell in real time, accurately grasp the battery's operating status, prevent abnormal states such as overcharging, over-discharging, overcurrent, and short circuits, and effectively avoid safety accidents such as thermal runaway, combustion, or explosion caused by battery runaway.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. This utility model adopts a modular battery pack structure, which supports parallel connection between multiple battery packs. The battery capacity can be flexibly configured according to the actual power and battery life requirements of the communication base station, which significantly improves the system adaptability and economy. It is suitable for different application scenarios such as macro base stations and micro base stations. The modular structure also facilitates maintenance and expansion, improves system reliability and extends service life.

[0027] 2. The safety valve in the battery module of this utility model can prevent risks such as thermal runaway and explosion; together with the built-in battery management system (BMS), it can realize real-time monitoring of battery operating status, fault early warning and equalization management, improve the intrinsic safety level and intelligent operation and maintenance capabilities of the whole machine, and meet the operation requirements of unattended communication base stations.

[0028] 3. This utility model adopts a hinged box structure, equipped with handles, wall-mounted brackets and flag-mounted fixing brackets, which can adapt to various installation environments; the external operation interface panel integrates power output, communication interface, maintenance interface and status indicator light, which facilitates wiring and monitoring and reduces the risk of misoperation; the aluminum alloy die-cast shell has the characteristics of high strength, corrosion resistance and excellent heat dissipation, ensuring stable operation of the equipment in harsh outdoor environments.

[0045] like Figure 2-6 As shown, the battery box body 1 is externally equipped with a handle 1-1, a wall-mounting bracket 1-2, and a flag-mounting bracket 1-3. The battery box is formed by die-casting aluminum alloy. A battery management system 6 is installed inside the battery box body 1.

[0046] This preferred embodiment comprises a battery box body 1, multiple battery packs 4, a battery management system 6, an operation interface panel 5, a safety valve system, and a mounting bracket structure. It adopts a modular design and intelligent control technology, making it suitable for complex and variable outdoor communication base station application environments. The battery box contains multiple battery packs 4, each consisting of 16 battery modules connected in series. Each module is equipped with a safety valve, which can actively or passively release pressure in the event of abnormal internal air pressure or increased temperature, improving the intrinsic safety level of the battery system and preventing systemic failures caused by thermal runaway of a single module. This safety structure significantly enhances the operational stability of the entire product in extreme environments and the safety protection capabilities for personnel and equipment. Each battery module uses high-performance cell materials, possessing advantages such as high energy density, stable discharge platform, and long cycle life. Combined with the parallel structure design of the battery packs 4, it effectively improves the overall output capacity and discharge current capability, widely adapting to the power consumption requirements of different communication devices and ensuring signal continuity and service quality. The entire system supports the parallel operation of multiple battery packs on demand, possessing excellent capacity expansion capabilities. It can be flexibly configured with single or multiple packs to meet the load requirements of different sites, achieving customized power supply solutions. Modular design not only improves product maintainability and standardization but also facilitates production, transportation, and subsequent replacement and maintenance. The internally integrated battery management system features comprehensive alarm protection functions, including overcharge, over-discharge, short circuit, overload, overcurrent, high temperature, low temperature, equalization management, and sleep control. It can monitor and dynamically adjust the status of each cell in real time, enhancing the system's intelligent operation.

[0047] The main body of the battery box 1 is integrally formed using an aluminum alloy die-casting process, possessing excellent structural strength and impact resistance, while also exhibiting superior corrosion resistance, waterproofing, dustproofing, UV resistance, and heat dissipation performance. Even in harsh outdoor environments such as exposure to sunlight, rain, dust, icing, and high humidity, it can maintain long-term stable operation, ensuring the normal power supply for communication equipment.

[0048] The lower cover 3 of the battery box is equipped with an operation interface panel 5. This panel integrates a power output port 5-1, a communication interface, a vent valve 5-3, a status indicator light 5-4, and a switch. It supports bottom plug-in connection, which is convenient for on-site wiring and maintenance operations. It is suitable for working in locations where it is inconvenient to open the cover, such as high altitude, corners, and towers.

[0049] A handle 1-1 is provided on the outside of the battery box body 1 for easy transportation and handling; at the same time, it provides a variety of installation options such as wall-mounted brackets, flag brackets, and angle steel tower fixing structures, which can meet various deployment needs such as wall-mounted, pole-mounted, flag-mounted, and ground-mounted, with good structural adaptability and installation flexibility, and is particularly suitable for various communication scenarios such as 5G communication base stations, micro base stations, and edge nodes.

[0050] This preferred embodiment is based on a modular design of battery cells. Multiple battery modules are connected in series to form a battery pack 4, and multiple battery packs 4 are connected in parallel to form an overall power supply system to achieve high capacity and high voltage output, so as to meet the needs of communication base stations for different power levels.

[0051] Multiple battery modules are connected in series to form a single battery pack 4, increasing the output voltage of the single pack; multiple battery packs 4 are connected in parallel to increase the overall system capacity and discharge current capability; the output power is supplied to the communication equipment through the power output port 5-1 in the operation interface panel 5.

[0052] The safety valve equipped in the battery module can effectively isolate faulty cells and prevent the fault from spreading to the entire battery pack.

[0053] The workflow is as follows: After the communication base station power supply system is started, the battery management system 6 first checks whether the status of each module is normal; if all parameters are within the safe range, the system closes and begins to discharge power. The series module provides high voltage output, and multiple parallel battery packs 4 share the load; electrical energy is stably output to the communication equipment through the power output port 5-1; the status indicator light 5-4 reflects the working status of the battery box in real time (such as operation, alarm, fault, etc.). The battery management system 6 continuously collects the status parameters of each module and analyzes and judges them; if abnormal temperature, voltage, or current is detected, an alarm signal is issued and protection measures are activated; if a potential runaway risk is predicted, the battery management system 6 can control the safety valve to release pressure in advance to achieve active protection. Once a module fails, the system isolates it, and other modules continue to operate normally; maintenance personnel can read data and determine the fault location through the external operation interface; only a single faulty module needs to be replaced, without replacing the entire battery box, reducing maintenance costs.

[0054] The battery box body 1 is made of die-cast aluminum alloy, which is lightweight and high-strength, suitable for high-altitude installation; it is equipped with handle 1-1 for easy manual handling; it can be quickly installed on communication poles, walls or flag-mounted equipment through wall-mounted fixing bracket 1-2 and flag-mounted fixing bracket 1-3.
