DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to the attached Figure 1 , the embodiment of the present invention provides an energy storage power supply for outdoor operations, including: Modular LiFePO4 battery pack, consisting of more than 4 hot-swappable battery cells, with a total capacity of 4kWh - 20kWh that can be expanded; Composite protective shell, made of carbon fiber reinforced polypropylene matrix and meeting the IP68 protection level; Multi-protocol output interface group, including USB-C or PD3.1 fast charging interface, XT60 DC interface and IEC60309 AC interface; Heat dissipation device, which controls the fan speed based on the internal temperature of the energy storage power supply to adjust the heat dissipation capacity; Rotatable lighting module, integrated with a COB LED array with adjustable color temperature from 3000K to 6000K, supporting 270° three-dimensional adjustment.

[0023] Specifically, the modular LiFePO4 battery pack can be adjusted according to the actual power consumption requirements of outdoor operations. When facing small outdoor projects with less power demand, a lower-capacity combination can be used; while in the face of large and complex outdoor operations with numerous electrical devices and high power consumption, the capacity can be expanded by adding battery cells. The battery cells can be replaced, added or reduced without interrupting the power supply, ensuring the continuity of operations; The composite protective shell is made of carbon fiber reinforced polypropylene matrix and has excellent mechanical properties. The addition of carbon fiber significantly improves the shell strength, enabling it to withstand external impacts such as collisions and frictions that may be encountered during outdoor operations, effectively protecting the internal battery and electronic components. At the same time, with the IP68 protection level, it can block the intrusion of water and dust in outdoor scenarios with heavy rain or sandy environments, ensuring the normal operation of the internal electronic devices of the energy storage power supply, extending the service life of the power supply, and enabling it to work stably under harsh outdoor conditions; The rich interface types of the multi-protocol output interface group meet the power consumption requirements of different devices, facilitating outdoor operators to keep the device batteries fully charged at all times.

The IEC60309 AC interface is suitable for devices that need to access alternating current, improving the versatility and practicality of the power supply; The fan in the heat dissipation device can intelligently adjust the speed according to the temperature information feedback by the internal temperature sensor. When the temperature is low, the fan runs at a low speed, reducing energy consumption and noise. As the temperature rises, the fan speed increases, enhancing the heat dissipation effect and quickly removing heat, ensuring that the inside of the power supply is always within the appropriate working temperature range, maintaining the stable and efficient operation of the power supply, and ensuring the reliability of the power supply during outdoor operations; The rotatable lighting module can flexibly adjust the color temperature in outdoor scenarios with complex and changeable light conditions. At the same time, when performing delicate operations, it can provide clear and bright lighting, facilitating accurate operation by the operator. The three-dimensional adjustment function enables the lighting direction to be adjusted omnidirectionally, providing sufficient and flexible lighting support for outdoor operations and improving operation efficiency and safety.

[0024] The composite protective housing includes: An outer bulletproof polycarbonate housing; A middle Kevlar fiber buffer layer; An inner electromagnetic shielding aluminum-magnesium alloy frame.

[0025] Specifically, the outer layer uses a bulletproof polycarbonate housing, which has extremely high strength and toughness and can resist high-intensity external force impacts, ensuring that the housing always serves as the first protective barrier against external hazards under complex outdoor conditions and enhancing the overall durability and reliability of the energy storage power supply; The Kevlar fiber buffer layer in the middle layer can effectively absorb and disperse the impact force, preventing the impact force from being directly transmitted to the inner layer structure and sensitive components such as batteries, avoiding damage to internal electronic components due to vibration, and reducing the risk of equipment failure caused by mechanical shock; The inner electromagnetic shielding aluminum-magnesium alloy frame. Aluminum-magnesium alloy has good electrical conductivity and low density, which can effectively shield external electromagnetic interference. At the same time, the shielding layer formed by the aluminum-magnesium alloy frame can block these external electromagnetic interferences outside, ensuring the stable operation of the internal circuit.

[0026] The multi-protocol output interface group meets the following requirements: DC output, adjustable at 12, 24, and 48 VDC, with a maximum continuous current of 100 A; AC output, automatically recognizes 110 VAC or 220 VAC, THD < 3%; Wireless output, supports the Qi2.0 protocol, with a maximum transmission power of 30 W.

It quickly detects the working status of the device, and judges information such as device type, starting current, operating parameters, etc. Based on these detection results, it preferentially tries to use DC power supply because DC power supply has advantages such as high efficiency and energy saving in some cases. If the device has abnormal startup or unstable operation under DC power supply, the device status detection unit will immediately trigger the switching mechanism to convert the power supply mode to AC power supply to ensure that the device can work normally, effectively improving the compatibility between the device and the power supply system, and ensuring that various devices can be successfully connected and operate stably in the complex outdoor environment.

[0039] Specifically, during the charging stage, the charge and discharge control logic intelligently adjusts the charging current and voltage based on the current battery charge, health status, and characteristics of the external power source to achieve fast and safe charging. When the battery charge is low, the charging current is appropriately increased to accelerate the charging speed. When approaching full charge, the current is decreased to prevent overcharging and extend the battery life. During discharging, the discharge power is dynamically adjusted according to the changes in the power consumption requirements of the device to ensure stable output power. The device priority control logic divides the electrical devices into priorities according to their importance in outdoor operations and requirements for power supply stability, and reasonably allocates limited power resources, ensuring the smooth progress and safety of outdoor operations. The environmental factor control logic fully considers the impact of environmental factors such as temperature and humidity on the performance of the battery and the device. By means of heat dissipation devices, it controls the temperature inside the power source to overcome stable operation in high-temperature environments, expands its applicable range, ensures the normal operation of the device in harsh environments, and extends the service life of the energy storage power source and electrical devices. The fault and exception handling logic is based on monitoring the operating status of the power supply system and electrical devices, and promptly discovers abnormal situations such as battery faults, circuit short circuits, and device overloads.
