Description

Technical Field

[0001] The present invention relates to the field of power supply technology, and in particular to a multifunctional equipment power supply collaborative integration system. Background Art

[0002] With the improvement of social production and living standards, the demand for power supply systems in team work scenarios is becoming increasingly diversified and complex. In industrial sites, field construction, emergency rescue, military battlefields and other environments, the power supply of teams usually needs to support a variety of equipment and tools, including communication equipment, lighting equipment, monitoring devices, power tools, etc. At the same time, due to the differences in voltage, power and interface requirements of different devices, the traditional single power supply method often cannot meet the diversified power demand. In addition, these scenarios may face power outages or insufficient external power supply, so higher requirements are placed on the stability and flexibility of the power supply system. At present, common power supply solutions on the market mainly include fixed power supplies and portable power supplies. Fixed power supplies have high power supply capacity, but their use scenarios are limited. They need to rely on fixed power networks and are difficult to meet the needs of mobility and decentralization. Portable power supplies, such as ordinary power banks or small power generation devices, although they have certain flexibility, often have defects such as insufficient power, short battery life, and single interface, and are difficult to support the continuous operation of high-power consumption equipment. In addition, the existing power supply equipment has low utilization efficiency of multiple input energy sources. Especially in the case of multiple energy inputs or multiple device outputs, energy distribution and management often rely on manual adjustment, which is inefficient and complex to use. As typical representatives of clean energy and emergency energy, flexible photovoltaic modules and hand-cranked generators have been widely used in the field of power supply in recent years. However, the technology to integrate them with high-energy batteries and combined battery packs and realize intelligent management is not yet mature. The current power supply system generally lacks the ability to uniformly manage multiple energy inputs, and it is difficult to achieve compatibility of multiple energy input methods (such as photovoltaic input, hand-cranked generator input, and high-energy battery power supply) with the output requirements of multiple devices in a single system. In addition, the existing power supply system also has obvious deficiencies in energy distribution and conversion efficiency, which is particularly evident in emergency and extreme environments.

[0003] Patent document CN118826218A discloses a multifunctional power supply device for outdoor emergency rescue. Through a central processing unit, a charging / discharging module, a lithium battery, an air pump module, a DC12V output module, an AC output module, a USB output module, a car emergency start module, etc., it can provide DC / AC power to individual users during outdoor activities, inflate car tires, and vacuum cleaners, etc. However, the power supply of the invented device can only rely on charging and replenishing the battery, and there is no design for handling battery failure. The application objects are also limited to individual users. Therefore, it still cannot achieve stable and efficient power output, nor can it meet the application requirements under emergency and extreme conditions and the diversified power demand in team work scenarios. At the same time, it lacks adaptability considerations to scenes requiring high mobility such as field construction, emergency rescue and military battlefields, and also lacks considerations on portability for human movement.

[0004] Therefore, there is an urgent need for a multifunctional equipment power collaborative integration system that can adapt to a variety of complex scenarios. The system should be able to effectively integrate multiple energy input methods, provide stable and efficient energy management and output capabilities, and thus meet the diverse power needs in team work scenarios.
