Description

Technical Field

[0001] This article belongs to the technical field of energy storage power supply, specifically involving a novel portable energy storage power supply system structure. Background Technology

[0002] Portable power banks on the market are generally geared towards civilian use. Their design concept and functional configuration are centered on meeting the basic power needs of ordinary consumer electronic devices. These power products usually only have simple charging and discharging functions, with a low overall technical threshold and a relatively simple structural design.

[0003] Currently, the output voltage of most civilian portable power banks is concentrated in the range of 5V to 20V, and the output power is generally less than 100W. This makes them unsuitable for the high power and high stability requirements of special equipment such as special vehicles, industrial testing equipment, and emergency communication devices. In terms of power management, civilian products lack professional battery status monitoring and protection mechanisms, and can only achieve basic overcharge and over-discharge protection. They are unable to accurately control key parameters such as individual battery voltage, temperature equalization, and charge-discharge cycle life, and cannot meet the dynamic response requirements of special equipment under complex working conditions. At the same time, in pursuit of lightweight and portability, civilian portable power banks often use simple shell packaging, which has limited heat dissipation performance. They are prone to overheating during long-term high-load operation, affecting the lifespan and safety of the equipment. Moreover, these products generally lack standardized communication interfaces, making it impossible to achieve data interaction with external systems and failing to meet the functional requirements of special equipment in terms of intelligent management, remote monitoring, and fault early warning.

[0004] In addition, power systems in special fields usually need to have characteristics such as vibration resistance, shock resistance, and wide temperature adaptability. However, existing civilian mobile power supplies have not taken into account such harsh usage scenarios in terms of structural strength and environmental adaptability, making it difficult for them to play an effective role in scenarios such as special vehicle mobile operations, outdoor emergency rescue, and temporary power supply in industrial sites.

[0005] In summary, existing civilian portable power supplies have significant limitations in terms of power output, management accuracy, structural stability, and functional expandability, and cannot meet the professional and high reliability requirements of power systems for special vehicles and special equipment. Therefore, there is an urgent need to develop a new portable energy storage power system structure that is suitable for special scenarios. Utility Model Content

[0006] To address the aforementioned issues, this paper proposes a novel portable energy storage power system structure. This structure includes a cover handle, a toothed heat dissipation cover, a housing, an AC / DC converter, a battery pack, a battery management system, a selector switch, an operating status indicator, a power indicator, a charging interface, a discharging interface, and a communication detection interface. The cover handle is located on the outside of the toothed heat dissipation cover, which has heat dissipation teeth. The toothed heat dissipation cover is detachably connected to the housing. The housing is composed of a front panel, side panels, and a bottom panel vertically connected. The housing houses the AC / DC converter, battery pack, and battery management system. The battery management system is located between the AC / DC converter and the battery pack. The selector switch, operating status indicator, power indicator, charging interface, discharging interface, and communication detection interface are all located on the housing front panel. The housing is designed using a modular approach. The housing panel, side panels, and bottom plate are vertically connected to form a robust structure, enhancing the overall strength of the power system. The AC / DC converter enables efficient conversion between AC and DC power. The battery management system precisely monitors and manages the battery pack, ensuring safe use and optimal performance. The integration of components such as the conversion switch, operating status indicator, and power indicator allows users to intuitively understand the power system's operating status and power level. The inclusion of charging, discharging, and communication detection interfaces enables rapid charging, stable discharging, and data interaction with external systems, meeting the functional requirements of special equipment in areas such as intelligent management, remote monitoring, and fault early warning. All components work together to build an efficient, stable, and intelligent portable energy storage power system. This design not only optimizes the power system's performance but also significantly improves its adaptability and reliability in various complex environments.

[0007] A handle is provided at the center of the outer side of the toothed heat dissipation cover. Mounting holes are provided around the perimeter of the toothed heat dissipation cover. The heat dissipation teeth on the outer side of the toothed heat dissipation cover are elongated and arranged parallel and equidistantly along the length of the toothed heat dissipation cover. Through the reasonable design of the heat dissipation teeth, the air circulation area is effectively increased, heat dissipation is accelerated, thereby reducing the internal temperature of the equipment and extending the service life of the equipment. At the same time, the setting of mounting holes allows the toothed heat dissipation cover to be firmly connected to the shell, enhancing the stability of the overall structure. This not only improves the heat dissipation performance of the equipment, but also takes into account aesthetics and practicality, enabling the new portable energy storage power system to operate stably in harsh environments.

[0008] The top of each plate around the casing has mounting holes that match the mounting holes around the perimeter of the toothed heat dissipation cover. The casing and the toothed heat dissipation cover are detachably connected by fasteners. Rubber sealing rings are used at the joints of the casing, and waterproof plugs are added to the interfaces. The detachable connection facilitates the maintenance and replacement of parts. The use of rubber sealing rings and waterproof plugs effectively prevents external factors such as dust and moisture from entering the inside of the equipment, enhances the waterproof performance of the equipment, and ensures the stable operation of the equipment under various harsh conditions.

[0009] The AC / DC converter is configured to receive external 220V AC power and convert it to 24V DC power. The input terminal of the AC / DC converter is connected to the charging interface via a wire, and the output terminal is connected to the positive and negative terminals of the battery pack via a wire. Through this connection method, the conversion and transmission of external AC power to the DC power of the battery pack is realized, providing stable power support for battery charging. The AC / DC converter has high conversion efficiency, which can efficiently convert the input AC power to DC power in a short time, reducing energy loss and improving charging speed.

[0010] The battery management system is connected to the battery pack, AC / DC converter, transfer switch and indicator lights via wires. The battery management system can obtain the remaining power and usage status of the battery pack, and intelligently adjust the charging strategy to extend the battery pack's lifespan.

[0011] The selector switch is a rotary multi-position switch with charging, discharging and off positions. Different working modes can be switched by rotating the selector switch. This design allows users to flexibly select the working mode according to actual needs, improving the practicality and convenience of the equipment.

[0012] The operating status indicator and the power indicator are arranged side by side in the middle of the housing panel. Both the operating status indicator and the power indicator are LED lights. Different colors of LED lights convey various information. The operating status indicator can clearly display the current working status of the device. Whether it is normal operation, fault indication or standby mode, it can intuitively inform the user through specific colors and flashing patterns. The power indicator adopts a segmented display method, which intuitively reflects the remaining power of the battery pack through the illumination of the light. This allows the user to grasp the power status of the device and charge it in time or adjust the usage strategy to ensure the continuous and stable operation of the device.

[0013] The charging and discharging interfaces are vertically arranged on the side of the housing panel. The charging interface is equipped with reverse connection protection and overcurrent protection devices, and the discharging interface is equipped with overvoltage, overcurrent and short circuit protection devices. Through the coordinated action of these protection devices, circuit damage caused by misoperation or external factors can be effectively prevented, ensuring the safety of the equipment and the user's electricity use.

[0014] The communication detection interface integrates a signal isolation circuit module, which connects to the data transmission terminal of the battery management system via a data cable. This internal signal isolation circuit module effectively isolates external interference signals and prevents internal signals of the battery management system from interfering with external devices, ensuring the electromagnetic compatibility of the entire system. The close connection between the data cable and the battery management system enables real-time monitoring and data transmission of battery status, providing strong support for the safe use and efficient management of the battery.

[0015] Beneficial effects:

[0016] By implementing a modular design for the casing, a robust structure is built through vertical connections between the casing panel, side panels, and bottom plate, enhancing the overall strength of the power system. The AC / DC converter enables efficient conversion between alternating current and direct current. The battery management system precisely monitors and manages the battery pack, ensuring safe use and optimal performance. The integration of components such as the conversion switch, operating status indicator, and power indicator allows users to intuitively grasp the working status and power status of the power system. The inclusion of charging, discharging, and communication detection interfaces enables rapid charging, stable discharging, and data interaction with external systems, meeting the functional requirements of special equipment in terms of intelligent management, remote monitoring, and fault early warning. All components work together to build an efficient, stable, and intelligent portable energy storage power system. This design not only optimizes the performance of the power system but also significantly improves its adaptability and reliability in various complex environments.

[0017] The rational design of the heat dissipation fins effectively increases the air circulation area, accelerates heat dissipation, thereby reducing the internal temperature of the equipment and extending its service life. At the same time, the mounting holes allow the finned heat dissipation cover to be firmly connected to the shell, enhancing the stability of the overall structure. This not only improves the heat dissipation performance of the equipment but also takes into account aesthetics and practicality, enabling the new portable energy storage power system to operate stably even in harsh environments.

[0018] The detachable connection between the housing and the toothed heat dissipation cover facilitates equipment maintenance and component replacement. The use of rubber seals and waterproof plugs effectively prevents external factors such as dust and moisture from entering the equipment, enhancing its waterproof performance and ensuring stable operation under various harsh conditions.

[0019] By connecting the input of the AC / DC converter to the charging interface via wires and connecting its output to the positive and negative terminals of the battery pack, the external AC power is converted and transmitted to the DC power of the battery pack, providing stable power support for battery charging. The AC / DC converter has high conversion efficiency, which can efficiently convert the input AC power to DC power in a short time, reducing energy loss and improving charging speed.

[0020] The battery management system can obtain the remaining power and usage status of the battery pack, intelligently adjust the charging strategy, and extend the battery pack's lifespan.

[0021] Different working modes can be switched by rotating a selector switch. This design allows users to flexibly choose the working mode according to their actual needs, improving the practicality and convenience of the equipment.

[0022] The LED lights convey various information through different colors. The operating status indicator can clearly display the current working status of the device. Whether it is in normal operation, fault indication or standby mode, it can intuitively inform the user through specific colors and flashing patterns. The power indicator uses a segmented display method to intuitively reflect the remaining power of the battery pack by lighting up the lights. This allows the user to grasp the power status of the device and charge it in time or adjust the usage strategy to ensure the continuous and stable operation of the device.

[0023] Through the coordinated action of various protection devices, circuit damage caused by misoperation or external factors can be effectively prevented, ensuring the safety of equipment and users' electricity use.

[0024] The internal signal isolation circuit module of the communication detection interface can not only effectively isolate external interference signals, but also prevent the internal signals of the battery management system from interfering with external devices, ensuring the electromagnetic compatibility of the entire system. Through the tight connection with the battery management system via the data cable, real-time monitoring and data transmission of battery status can be achieved, providing strong support for the safe use and efficient management of the battery.

The housing 10 and the toothed heat dissipation cover 2 are detachably connected by fasteners. Rubber sealing rings are used at the joints of the housing 10, and waterproof plugs are added to the interfaces. The AC / DC converter 3 is configured to receive external 220V AC power and convert it to 24V DC power. The input terminal of the AC / DC converter 3 is connected to the charging interface 4 via a wire, and the output terminal of the AC / DC converter 3 is connected to the positive and negative terminals of the battery pack 11 via a wire. The battery management system 12 is connected to the battery pack 11, the AC / DC converter 3, the selector switch 5, and each indicator light via wires.
